This is a kind of image processing algorithm in order to realize a seamless video wall and improve the quality of images. / Nowadays, screens are very common in our daily life. There are several di erent
kinds of screens, LCD, LED, OLED, ULED and so on. LCD screens can display
high-resolution pictures while LED has advantages of low energy consumption and
wider color range. This project has two goals. The rst one is to achieve a seamless
display screen which consists of 9 LED backlit LCD boards. The second goal is to
improve image quality, which is enabled by the combination of LED and LCD. There
are two main problems that need to be solved in this project. The rst problem is
brightness correction. Because of the projection method and the distance between
lights and nal screen, there are di erent kinds of overlapping situations and distinct
lines on screen. The other one is the combination of LED and LCD. The algorithms
need to be developed to ensure that RGB LEDs and LCD panels display the same
picture and to address some problems caused by the LCD module. / Thesis / Master of Applied Science (MASc)
