CSTN LCD Frame Rate Controller For Image Quality Enhancement

This thesis is mainly focused on FRC (Frame Rate Control) method which can be used for LCD
panels, where a new algorithm is proposed to improve the flicker problem. The proposed algorithm can
be implemented by simple digital circuits with low power consumption.
The proposed design can be applied in both mono- and color- STN panels. It can generate 32768
colors in a panel without any flicker and motion line problems, which can only allow 8 colors
originally.
The major contribution in this thesis is to add a location number to each pixel of the panel.Notably, the numbers for all the pixels can not be a regular pattern. Otherwise, the flicker problem is
resolved at the expense of a serious motion line issue. The consequence is poor display quality. To
resolve both the flicker and motion line problem, we propose to employ a PRSG (Pseudo Random
Sequence Generator) which generates a non-regular number sequence for all the pixels. Therefore, all
the ON pixels can be dispersed on the panel in all frames.
