Abstract


As a kind of LCD panel color enhancement technique, FRC pixels dithering algorithm is widely used, it can use relatively low wide driver IC achieve high width, colour more rich display effect. Existing FRC algorithm pixel jitter can be subdivided into FRC algorithm and Hi - FRC algorithm, for 6 - bit driver IC, the former can be realized on the basis of grade 64 gray-scale level 253 gray-scale display, while the latter can achieve full 256 level gray scale display. But Hi - FRC algorithm will Hi - FRC algorithm will cause uneven gray level difference problem, and aggravate the FRC noise. This article will discuss the Hi - FRC algorithm generated by these two problems, to understand its mechanism. Based on this, advances based on five frames loop Fi - FRC algorithm and demonstrates the rationality of the algorithm, and algorithm for the Fi - FRC pixel dithering algorithm can graphics and its output are expounded, and the design of the algorithm. Through theoretical derivation and experimental design and verification, confirmed the Fi - FRC algorithm is a feasible FRC pixel jitter. Can solve the problem of uneven gray level difference and reduce the noise of FRC.
