Abstract:
1. An overdrive computation apparatus for generating a desired overdrive gray-level value, the apparatus comprising: a first addition/subtraction device for receiving a first overdrive gray-level value OD a priority encoder for generating a first decision signal according to the one of the intervals in which the difference value lies; a computation device for receiving first gray-level data and converting the first gray-level data to operated gray-level data by at least one of a bit-shifting operation and a first adding/subtracting operation, by the respective corresponding computation according to the first decision signal, wherein the first gray-level data indicates a value lying between the ith first gray-level index value X(i) and the (i+1)th first gray-level index value X(i+1); and a second addition/subtraction device, for receiving the operated gray-level data and the first overdrive gray-level value OD
