Abstract
The present invention can realize better display of a dynamic image, and in addition, can make storage capacity of a memory smaller. A data conversion circuitcompares display dataof an n-th frame from the outside and display dataof the (n−1)-th frame stored in the memoryto generate a driving data signalto deliver to a driver. Each time when a memory control circuitreads display data q, q, q, qcorresponding to 20 pixels out of the display dataof the (n−1)-th frame, the memory control circuitcompresses display data d–dof 20 pixels out of the display dataof the n-th frame from the outside to generated d, d, d, d, and stores the generated data into the same area where the display data q, q, q, qof the display data of the (n−1)-th frame have been stored.
