Abstract:
1. A driving system for use in a displaying device capable of gradation display with respect to each of pixels, wherein: input data for producing grayscales is k-bit data, where k is an integer and 6≦k<m (where m is an integer not less than 9); when k≦7, 0 is added to lower-(8−K) bit of the input k-bit data, and data obtained by adding 0 is stored in a frame memory; when k≧8, upper-8-bits of the k-bit data is stored in the frame memory; the input k-bit-data is converted into m-bit-data in an independent γ-processing block; overshoot-driving is carried out based on current frame data and previous frame data wherein the current frame data is upper-8-bit data of the γ-processing data, and the previous frame data is data stored in the frame memory; lower-(m−8) bit data of the current frame data is added to data resulted from the overshoot-driving so that m-bit overshoot-driving data is created; and the m-bit overshoot-driving data is processed in a pseudo bit-depth extension block, and is outputted in the form of 8-bit data.
