  • Apparatus and method for gray-scale and brightness display control
    Patent number: 6288698
    Abstract: Frame-rate control electronic provides gray-scale display control algorithm for STN LCD devices and constant brightness display with randomized pattern algorithm. Even distribution control of phase number reduces screen flicker and stabilizes gray-scale display. Randomized and scrambled phase number control eliminates screen beating artifacts, such as when image includes dither and checker patterns. Programmable parameters, such as tuning value, phase number matrices, and frame offset numbers, may be chosen flexibly to optimize conditions to certain display.
