摘要： In order to reduce power consumption of a display device when a still picture is to be displayed, a display area of the device is subdivided into a plurality of Still Picture Refresh Groups (SPRGoP's), with each SPRGoP consisting of n pixels. All n of the pixels are charged in every one of sequential frames when a motion picture mode is in effect. Less than all of the n pixels of each SPRGoP are refreshed in each frame of an N-frame refresh cycle when a still picture mode is in effect. Different schemes for cycling through the n pixels of each SPRGoP are disclosed.

摘要： A signal processing device includes a memory in which a color correction data is stored. The memory stores a first color correction data having the same number of bits as an input image data and a second color correction data having fewer number of bits than the input image data. The number of color correction data corresponding to a low gray-scale range increases and the number of color correction data corresponding to a high gray-scale range decreases by the same amount that the number of the color correction data corresponding to the low gray-scale range increased. Thus, a color characteristic corresponding to the low gray-scale range may be improved without changing the total number of color correction data.
