This thesis deals with the design of module for control of biaxial cartesian manipulator. Control module recieves signals STEP and DIR from PLC - these signals can have frequency up to 100 kHz. They are processed by the module and send to inputs of drivers, which control motors of biaxial manipulator. Both axis of manipulator are driven simultaneously. PLC is not able to manage this process without this module. Adjusted parameters are displayed on LCD display. Control module is disturbance-resistant. All signals are isolated by fast optocouplers, which guarantee minimum distortion of signals. Data are processed by microprocessor ATXMEGA. Program of microprocessor is written in the C language. It is possible to switch module to NPN or PNP logic and it is also possible to select output voltage 5 or 24 V according to the type and adjustment of used driver for motor control.

This thesis describes the design of portable multi-purpose measuring device with Microcontrollers from Microchip running on battery power, for displaying the measured signal uses a graphical LCD with a resolution of 240x128. The device is equipped with an oscilloscope and multimeter with auto range.

This paper deals with design and implementation of the information table control system. It is designed using UML model language and Rational Rose development tool. System implementation is based on the modern Microsoft .NET Framework component.

The concept of "visual fatigue" has been studied for 70 years or more. In that time, no single metric of measuring visual fatigue nor one agreed-upon set of tasks to induce visual fatigue has been settled upon. Not even a robust definition of visual fatigue has been established. This research worked to solve some of those problems. This research first set out to develop an index of visual fatigue that could be used effectively in quantifying the subjective experience of visual fatigue. Then it sought to create a set of measurable tasks, representative of office work, that would induce visual fatigue. Taking these two developments, an experiment using human participants was conducted to validate these developments and work toward solving two issues in the visual fatigue field: how visual display technology and ambient illumination affect the onset of visual fatigue. A 4x4 within-subjects design was developed and executed to study how these two independent variables affected ratings of visual fatigue, performance on the task battery, subjective image quality judgments, and contrast sensitivity shifts. Two cathode ray tube (CRT) and two active-matrix LCD (AMLCD) monitors were used in this study. While many instances of the monitors as a whole caused significant differences in reports of visual fatigue, performance, subjective image quality, and contrast sensitivity loss, only a slight effect of display technology was found. Four of eleven visual fatigue and two of eight subjective image quality dimensions showed that the LCD monitors induced more visual fatigue and were rated poorer than the CRT monitors. Ambient illumination levels of 0, 300, 600, and 1200 lux affected all four groups of dependent variables. On the whole, lighting caused visual fatigue, with "watery eyes" and "glare from lights" being adversely affected by brighter lighting. The 0 and 1200 lux were associated with the worst performance, while 300 lux was associated with the best performance. Subjective image quality was affected by lighting, with increasing lighting causing bothersome screen reflections and more temporal (e.g., flicker and jitter) distortions; 600 lux induced more reports of image sizing anomalies. Finally, it caused significantly worse shifts at the 6.0 c/deg spatial frequency on the contrast sensitivity test. The data show that lighting of 300 lux is the best of these four illumination levels. The results of this study not only contribute to the body of research in the areas of display technology and ambient illumination, but several developments of this research are offered to the research community: a complete survey metric of visual fatigue, a standardized battery of tasks for studying visual fatigue and image quality, and a comprehensive subjective image quality survey. / Ph.

The immersive virtual reality (VR) and the optical see-through augmented reality (AR) are expected to revolutionize human lives in work, education, entertainment, healthcare, spatial computing, and digital twins, just to name a few. Next-generation VR/AR devices should exhibit a wide field-of-view (FoV), crisp image without screen-door effect, high dynamic range, compact form factor and lightweight, and low power consumption. Such demanding requirements pose a significant challenge to traditional direct-view display panels. To address these technical challenges, novel approaches need to be proposed. This dissertation is devoted to developing next-generation high-performance display light engines toward high resolution density, high optical efficiency, wide color gamut, and small form factor. These emerging solutions will fuel the growth and accelerate the widespread applications of VR/AR devices. In Chapter 2, we propose practical measurement methods to characterize the halo artifacts of miniature light-emitting diode (mini-LED) backlit liquid crystal displays (LCDs). After measuring and characterizing a high dynamic range (HDR) light engine, we propose and develop field sequential color (FSC) LCDs for high-end virtual reality (VR) devices in Chapter 3. Such an FSC LCD can triple the resolution density and optical efficiency via eliminating color filters. To further mitigate the color breakup (CBU), we also propose to combine mini-LEDs with FSC LCDs to enable progressive emission and achieve a higher frame rate (~ 600 Hz). To quantitatively compare the CBUs corresponding to simultaneous emission, progressive emission, and stencil algorithm, we adopt the CIEDE2000 color difference as a metric. Quantitative simulation results of the CBU indicate that a 600-Hz subframe rate can help mitigate the CBU dramatically. Micro organic light-emitting diode (micro-OLED) exhibiting high-resolution density and high contrast ratio is another type of display for high-end VR devices. More specifically, white micro-OLED is currently employed because it helps ease the manufacturing difficulty. In Chapter 4, we optimize the layer thicknesses to achieve a maximum efficiency while keeping a decent color gamut. We also push the limit of color gamut toward ~ 95% Rec. 2020. Lastly, liquid-crystal-on-silicon (LCoS) offers great potential for achieving high-efficiency and high-resolution waveguide-based AR displays. In Chapter 5, several strategies are proposed and developed to improve the performance of LCoS microdisplays and enable a small pixel size. In Chapter 6, we briefly summarize our major accomplishments.

電子產業為台灣主流產業，相關化學品使用量很大，過去多仰賴國外進口，是台灣傳統化學化工產業可用以轉型並切入的利基點。但台灣電子產業製造廠對本土化學材料供應商卻信心不足，有時根本連上線測試的機會都沒有。D公司是作者曾經任職的電子化學材料公司，也是A光電公司(LCD面板製造商)與E化學公司合資的公司，A公司的策略考量為掌握面板的上游原物料，E公司之策略則為穩定下游產品出海口。A光電公司知道要做什麼樣的產品，E化學公司則在過去累積了許多特用化學品的專業知識，所以D公司事實上是所謂know-what and know-how的結合，是電子化學材料公司轉型成功的一個案例。 本研究為導入邱志聖（2014）的4C架構，並分析D公司如何以產業的後進者，卻能克服日本競爭者的先行者優勢，而成功的關鍵點，並以此作為後續其他進入此領域或相類似產業公司的參考。藉由D公司與此產業主要競爭對手日本化學材料公司的4C比較分析可以看出，外顯單位效益成本涵蓋範圍廣，大家各有勝負，很難點出問題的核心及思考解決的策略；又日本化學材料公司的道德危機成本低於D公司，很難立即改變；但D公司的資訊交易成本比日本競爭者低(因為客戶A公司是同集團公司)。這也許是一個很好的切入點，所以D材料公司的行銷策略方向與順序為先利用降低交易成本的方式(與客戶建立合資公司)，進而提升技術與成本降低等外顯單位效益成本的競爭力，並藉著產品導入的機會與實績，逐漸提升與建立聲譽(降低道德危機成本)，再利用時機點的掌握與對手的可能犯錯，有策略的解決及導入有高替換成本的產品，最後再以此更強化道德危機成本。 本研究案例可提供傳統化工公司轉型之行銷策略參考，亦可適用於其他行銷門檻較高的產業。 / The electronic industry is one of the major industries in Taiwan. The chemicals consumption in this industry are huge and most imported from abroad. This could be the right industry or relative new area that the traditional chemical company in Taiwan can transform to. “D” company is a joint venture of “A” optoelectronic company (LCD panel maker) and “E” chemical company. “A” company knows the electronic products and technology trend, while “E” chemical has experience and professional knowhow in specialty chemical domain. “D” company possesses the knowledge of “know-what” and “know-how”, and is a successful chemical company in electronic industry. This study introduced the “4C Framework of Strategic Marketing Analysis” (Chiou 2014) and analyzed the key points that how the “D” company can succeed as a latecomer in the electronic chemical industry. By means of 4C analysis, it is clear to identify that the C2 (cost of information search) in “D” company is much lower than competitors due to belonging to the same group with major customer. By this, “D” company has the platform and advantages to further reduce the cost of utilities, such as technology learning curve and cost structure. By successfully introducing the products to customer one by one and build-up the credibility and reputation step by step, this can reduce the cost of moral hazard. However, the cost of asset specific is difficult to overcome. Sometime it needs to wait for the opportunity and/or the mistakes made by the competitors. With the overcome of cost of asset specific can bring more credit and reputation to further reduce the cost of moral hazard. This case study can be applied as the reference of strategic marketing analysis for transformation of traditional chemical company to electronic chemical company. It is also suitable in the area with high marketing barrier.

Because the industry is situated in a competitive environment that changes drastically, there exist several important issues that deserve further study, including how to identify core resources and core competences of the companies, consider development of enterprise resource bases, help management formulate the most adequate competitive strategies, and allow companies to continuously grow and develop in the competitive environment. This study adopts the qualitative case study method, where it uses three leading manufacturers that have the largest production output in Taiwan’s large-size TFT-LCD industry in 2006 (AU Optronics, Chi Mei Optoelectronics, and Chunghwa Picture Tubes, LTD.) as the subjects of this case study to conduct in-depth research on contents of and correlation among their core resources, core competences, competitive strategies, and competitive advantages. By induction from reference materials such as existing TFT-LCD-related data and the resource-based theory, as well as case study and analysis, this study presents main findings as follows: 1. The core resources owned by Taiwan’s TFT-LCD manufacturers come from combinations of unique heterogeneous resources owned by the companies, where their most important resource is intangible resource, their most important core competence is organization capability, their main competitive strategy is the cost leadership (or concentration) strategy, and their main corporate competitive advantage is organization capability. 2. Every TFT-LCD manufacturer in Taiwan is a combination of unique heterogeneous resources, so that each company performs differently from its competitors. 3. Correlation can be found in core resources, core competences, competitive strategies, and competitive advantages of Taiwan’s TFT-LCD manufacturers: core resources and core competences of the companies are the basis of formulation and execution of competitive strategies; corporate competitive advantages result from core resources and core competences, and the main resource is core competence; when a company makes profits, it is going to continuously develop company resources and competences, in order to maintain corporate sustainable competitive advantages.

Depuis les années 50, la récupération de la phase d’un faisceau optique diffracté par un objet quelconque, est un sujet important dans plusieurs domaines scientifiques, comme la microscopie, l’astronomie et bien d’autres. Généralement, les méthodes qui le permettent se divisent en deux grandes catégories : les méthodes interférométriques et les méthodes itératives basées sur la propagation du faisceau. L’intérêt de ces dernières, réside dans le fait qu’elles sont moins sensibles au bruit, et leur implémentation expérimentale est plus simple. Aussi, le développement des techniques informatiques a rendu cette approche plus rapide et plus intéressante. Cependant, même si l’efficacité de ces méthodes a été démontrée dans plusieurs domaines, leur utilisation est restée limitée à cause de certaines exigences sur les conditions expérimentales, et à la non-convergence de leur algorithme vers une solution unique dans un grand nombre de cas. Ceci est encore plus vrai pour les objets dits "objets complexes", possédant une amplitude et une phase, ce qui réduit fortement leur champ d’application. Afin de surmonter ces problèmes de convergence, diverses stratégies expérimentales ont été développées. Elles ont toutes comme principe d’introduire de nouvelles contraintes bien connues dans le plan de l’objet. Cela permet d’augmenter le nombre de spectres acquis, et donc accroitre et diversifier les sources d’informations sur l’objet de base, ce qui va aider l’algorithme itératif à converger plus rapidement vers une solution finale et unique. Comme exemple de ces stratégies expérimentales, on peut acquérir plusieurs spectres provenant de différentes zones de l’objet, ou moduler la longueur d’onde du faisceau incident, ou même enregistrer les spectres dans des plans parallèles, connectés entre eux par la transformée de Fresnel. Dans ce contexte, le présent travail vise à démontrer expérimentalement une technique connue sous SSPR (Spread Spectrum Phase Retrieval), proposé en 2007 par Zhang, tout en lui introduisant un certain nombre de modifications, afin de la rendre plus pratique. L’idée consiste à moduler le front d’onde de l’objet par M phases aléatoires, générées avec un modulateur spatial de lumière à base de cristaux liquides (LC-SLM), puis enregistrer dans le plan de Fourier les M spectres correspondants. Ces M spectres seront ensuite utilisés dans un algorithme itératif permettant de remonter au front d’onde de l’objet initial, en simulant la propagation du front d’onde entre les deux espaces, spatial et fréquentiel.La première partie de cette thèse comporte une étude détaillée sur les modulateurs spatiaux de lumière, afin de pouvoir choisir le mieux adapté à notre application. Une fois que le modulateur à base de cristaux liquides (LC-SLM) est sélectionné, on présentera ses caractéristiques techniques, ainsi que les tests et les étapes de calibrations nécessaires pour assurer son fonctionnement linéaire et optimal. Ensuite, on montrera plusieurs types d’applications possibles avec ce composant, et dans divers domaines scientifiques, comme l’holographie, la microscopie, l’optique adaptative ainsi que les méthodes interférométriques permettant de reconstruire la phase d’un faisceau lumineux. Dans la deuxième grande partie, on concentre notre travail autour de la méthode itérative SSPR. On montrera comment on peut rendre l’application de cette méthode plus simple en utilisant un modulateur spatial de lumière à base de cristaux liquides, et en travaillant dans le plan de Fourier à la place du plan de Fresnel. Cependant, après avoir appliqué expérimentalement cette méthode, on remarque que les résultats obtenus sont très mauvais par rapport aux résultats des simulations. On effectue donc, une étude détaillée concernant les sources de bruits pouvant être responsable de la dégradation de la qualité des reconstructions obtenues. [...] / Since the 50s, recovering the phase information of a diffracted beam has a major interest in several fields such as microscopy, astronomy and many others. Generally, the solutions fall into two broad categories: interferometric methods and iterative methods based on beam propagation. The advantage of the latter is that they are less sensitive to noise, and their experimental implementation is simpler. Also, the progress in computer technologies as well in digital imaging devices makes the application of this approach easier and more interesting. However, even if the effectiveness of these methods has been demonstrated in several fields, their use remained limited because of certain requirements on the experimental conditions and the non-convergence of their algorithm to a single solution in many cases. This is even more true for the so-called "complex objects", having an amplitude and a phase, which can greatly reduce their field of application. To overcome the convergence problems and improve the robustness of these methods, many experimental strategies have been employed. They are all based on the same principle, which consists of introducing new well-known constraints in the object plane. This increases the number of acquired spectrum, and therefore diversifies the sources of information about the starting object, which will help the iterative algorithm to converge more quickly towards the final solution. As examples of such experimental strategies, one can record several spectra from different areas of the object, or modulate the wavelength of the incident beam, or also acquire the spectrums across two or more parallel planes connected through Fresnel or Fourier transform.In this context, the present work aims to experimentally demonstrate a technique known as SSPR (Spread Spectrum Phase Retrieval), proposed in 2007 by Zhang, while modifying it in order to make it more flexible. The idea is to introduce, using a liquid crystal spatial light modulator M strong phase modulation into the object field, then record in the Fourier plane the M corresponding spectrums. These M acquisitions will then be used in an iterative algorithm what will allow us to recover the object wavefront by simulating the propagation of the light between spatial and frequency spaces. The first part of this thesis includes a complete study on spatial light modulators; in order to select which one will be best suited for our application. Once liquid crystal spatial light modulators are selected, we present their technical characteristics, as well as the calibration tests needed to ensure their linear and optimal functioning. Then we show several possible applications with this type of component, in various scientific fields, like holography, microscopy, adaptive optics and interferometric methods to reconstruct the phase of a beam.In the second part, we focus our work around the SSPR iterative method. We will show how to make the application of this method simpler by using a liquid crystal spatial light modulator, and by working in Fourier plane instead of Fresnel plane. However, after applying SSPR we have noticed that the quality of experimental results is very inferior to the quality of simulation results. Therefore, a detailed study of the noise sources is conducted. Each of these noise sources adds its own contribution, yet modulator cross-talk remains the factor that deteriorates the most the quality of reconstruction. In fact liquid crystal spatial light modulators are known to have a strong cross-talk between their pixels commonly recognized as fringing field effect. As the pixels are micrometric, each addressed one affects its neighbors, and thus, the phase retardation obtained from a pixel will not be uniform over its entire surface. This will result in a blurring effect of the desired sharp edge between the pixels; therefore, the real displayed phase map will be very different from the addressed one. [...]

台灣最早投入TFT LCD是在1991年。發展早期只有兩家小公司，且受困於日本的技術屏障以及經營規模，一直無法有大格局的突破。直到1998年起，由於經濟開始衰退，日本方才開始陸續釋出TFT LCD相關技術，以授權或技轉方式讓技術開始擴散，此時方有多家台灣廠商開始陸續投入TFT LCD這個行業。 經過多年的努力，政府也漸漸開始重視TFT LCD產業，並且在2003年提出「兩兆雙星」五年國家經濟發展計畫，提供各種資源，全力扶植IC與TFT LCD兩項產業，其中TFT LCD被看好是台灣下一個產值破兆的產業，繼晶元代工之後下一個延續國家科技命脈的蓬勃生機。 從早期多數人連什麼是LCD都沒聽過，迄今八年時間，台灣LCD產業已經蓬勃發展，不僅擁有多家世界級大廠，亦成為全球平面顯示器重鎮。2007年也是台灣TFT LCD面板廠自成立以來最賺錢的一年，台灣整體平面顯示器產值首次超越韓國，整體產值並首度破兆，達到1兆2,849億台幣，其中台灣TFT LCD的產值就佔1兆2,149億台幣，佔全球TFT LCD總產值的44.5%。截至2007年為止，台灣本土TFT LCD上下游產業相關廠商共超過九十家，貢獻台灣GDP超過13%。 本文希望以TFT LCD上游材料行業背光模組為例，進行智慧財產與產業調查之工作，試著審視台灣TFT LCD關鍵零組件「背光模組」主要參與者之專利，藉由連結傳統專利分析與產業分析，從中找到能結合產業事實、專利品質和重要性的研究方法與結果，期能為台灣的背光模組行業，甚至是廣義的TFT LCD零組件行業提出一點意見與貢獻。 / Taiwan first engaged in TFT LCD industry in 1991. Only two small companies involved in the early stage; because of technical barriers established by Japan and insufficient economic scale of operation, there had been no breakthrough. Until 1998, the recession began, so that Japanese began to release the TFT LCD-related technologies by licensing or technology transfer, and resulting in the spread of technology. At this stage there are several Taiwanese manufacturers began to actively engage in TFT LCD industry. After years of efforts, the government has gradually begun to pay attention to TFT LCD industry. In 2003 the government put forward the "Two Trillion, Twin Stars" five-year national economic development plan, said plan provides resources to fully support both IC and TFT LCD industry, wherein TFT LCD is deemed next trillion industry, like Foundry, and may continue the lifeline of national science and technology. In the beginning, most people never heard of LCD. After eight years, Taiwan's LCD industry has flourished, not only has a number of world-class factories, but also has become a global center for flat panel displays. 2007 is also the most profitable year for Taiwan TFT LCD panel makers since their establishment. Taiwan's overall output value of flat panel displays exceed Korea for the first time; the overall revenue is about one trillion 2,849 billion Taiwan dollars, wherein Taiwan's TFT LCD accounted for 1 trillion 2,149 million Taiwan dollars, which also accounts for 44.5% share of the global TFT LCD output value. As of 2007, there are over 90 Taiwan companies related to TFT LCD industries, said companies contribute over 13% of GDP in Taiwan. This author wishes to take TFT LCD backlight industry as an example, performing investigation of intellectual property and industrial work, and try to examine the key patents of key players in the industry. The author looks forward to finding a new way to combine traditional patent analysis and industry analysis method, and make some contribution to the industry.

TFT-LCD（薄膜電晶體液晶顯示器）是台灣全力發展的重點產業。TFT-LCD 產業特徵是專業分工產業，LCD產業價值鏈可分成上游材料廠商、中游面板廠商、下游應用廠商。主要的上游零件及材料包括玻璃基板(glass substrate)、彩色濾光片(color filter)、偏光板/膜(polarizer)、背光模組(backlight module)、驅動IC(Driver IC)、配向膜(alignment layer)。 LCD面板生產所需要的這些原材料占面板生產總成本的70％以上。對面板製造商來說，透過整合減少成本成為一個重要的議題。許多面板的關鍵零組件是設計導入(design in)的產品，對於面板設計，需要配合製造商的要求和規格。所以面板廠商和關鍵零組件廠商之間的快速溝通和反應是非常重要。 目前部分材料是從國外進口的，其中配向膜是日商擁有90%的市佔率。雖然LCD面板成本結構中的比重不高，但是液晶配向膜是決定液晶顯示器面板品質的關鍵材料。主要的配向膜廠商分別是日產化學和JSR。雙方都是日商的化學公司。JSR是2005年投入台灣市場，設立JSRmicro(台灣捷時雅邁科股份有限公司)，日產化學則是2010年才進入台灣市場。而且日產化學是液晶配向膜的先鋒者，10年前的市占率大約80%，但是今年降低到50%。日產化學進來台灣時，透過日系綜合商社來交易。而JSR在台灣則是透過台灣的中間商(華立通路商)來交易。 本研究以日系液晶顯示器關鍵材料配向膜廠商「台灣日產化學」為實例，進行專業訪談。探討台灣日產化學之中游面板廠商的產業鏈，並希望運用邱志聖(2010)之策略行銷4C架構分析，進行深入探討日產化學在台灣市場中，如何降低台灣LCD面板廠商的交易成本包含外顯單位效益成本、資訊搜尋成本、道德危機成本、專屬陷入成本，進而了解此公司的競爭優勢，繼而進行跟競爭對手的4C成本比較分析，提供個案公司建議。 本研究目的為了解： 1.日產化學跟客戶之間的4C關係 2.日產化學與通路商之間的關係 3.日產化學跟競爭對手(JSR)的作法比較 研究結果發現： 1.中間商的選擇、數量、提供的產品種類多寡，以及中間商提供的服務都會影響到日產化學對面板廠商的交易成本。 2.相同產業內供應商提供的產品種類多寡會影響到對面板廠商以及中間商的交易成本。 3.製造商之知名度的高低會影響到中間商的選擇權力。 / TFT-LCD (thin film transistor liquid crystal display) is one of the key industries in Taiwan. TFT-LCD industry is characterized as a specialization industry. The LCD industry value chain can be divided into upstream materials manufacturers, the midstream panel manufacturers, and downstream application vendors. Upstream material parts include glass substrate, color filter, polarizer film, backlight module, the driver IC, and alignment layer. These essential components needed in LCD panel production account for more than 70% of the total cost in panel production. Therefore an important issue for panel makers is to reduce costs through integration. As many of the key components of the panel is the “design in product”, which need to be designed according to manufacturer's requirements and specifications, rapid communication and response between panel manufacturers and key components manufacturers is very important. Some materials are imported from abroad; Japanese companies have 90% market share in the alignment film market. Although the proportion of the cost structure of the LCD panel is not high, but the alignment layer is the key material to determine the quality of liquid crystal display panel. Two main alignment film makers are Nissan Chemical and JSR. They both are Japanese chemical companies. JSR devotes into Taiwanese market in 2005, and established JSRmicro. Nissan Chemical started its business in Taiwan at 2010, by establishing Taiwan Nissan Chemical. Nissan Chemical is the pioneer in liquid crystal alignment film and once had approximately 80 percent of market share 10 years ago, but it has declined to 50% as of now. Nissan Chemical transact through Japanese Sogo Shosha in Taiwai. JSR transact through Taiwanese intermediaries (Wahlee distributor) in Taiwan. In this study, Japanese liquid crystal alignment layer manufacturer Taiwan Nissan Chemical were professionally interviewed, then explored between Taiwan Nissan Chemical and the panel manufacturers’ industry chain. This study will also apply strategic marketing 4C framework for analysis, then conduct an in-depth investigation on how Taiwan Nissan Chemical reduces transaction costs for Taiwan LCD panel manufacturers, illustrate the company's competitive advantage through the transaction costs analysis, including buyer utility cost, information searching cost, moral hazard cost, and asset specificity cost, and lastly compare with the competitor’s transaction cost. The purposes of this research are: 1. The 4C relationship between Nissan Chemical and the client 2. The relationship between Nissan chemical and the distributors 3. The 4C comparison between Nissan Chemical and the competitor (JSR) The results of study show that: 1. A choice of intermediaries, the number of intermediaries, the number of product that intermediaries offer, and the services intermediaries provide will affect the transaction costs of Nissan Chemical for panel makers. 2. The product range provided by the suppliers within the same industry would affect the transaction costs of panel makers and intermediaries, 3. The well-known level of the manufacturer will affect the power of choice for intermediaries.
