Abstract
Disclosed herein is a display device in which input data is written to a RAM as current frame data and read from the RAM as preceding frame data. Then, the current frame data and the preceding frame data are added up in a correction circuit and the result is subjected to an overdriving processing. After this, the processed (over-driven) data is assumed as current frame corrected data, which is then written to the RAM. The written corrected data is read from the RAM and subjected to a double-speed driving processing.
