Patent ID: 7164415

Claim:
A display device for displaying according to display data from an outside, comprising: a display panel; a driver circuit which receives a driving data signal and drives said display panel according to said driving data signal; a memory which stores said display data; and a display data conversion circuit which compares display data of an n-th (n is a natural number) frame from outside with display data of an (n−1)-th frame temporally stored in said memory, generates said driving data signal for displaying the n-th frame, based on a comparison result, and produces said driving data signal to said driver circuit, wherein: said display data conversion circuit corrects said display data of the n-th frame based on said comparison result and generates said driving data signal based on the corrected display data of the n-th frame for displaying the n-th frame, when a difference between said display data of the n-th frame and said display data of the (n−1)-th frame is larger than a predetermined value that is not equal to zero, and said display data conversion circuit generates said driving data signal based on said display data of the n-th frame without correcting for displaying the n-th frame, when a difference between said display data of the n-th frame and said display data of the (n−1)-th frame is less than or equal to said predetermined value.
