摘要： PROBLEM TO BE SOLVED: To convert data read from a RAM to be input to an analog-digital conversion circuit into a gradation bit number/pixel by making the gradation bit number/pixel variable and storing data of designated gradation bit numbers of the maximum gradation bit number or less in a display data RAM as they are.
SOLUTION: A driver IC for supplying a data signal corresponding to the gradation bit number/pixel of a display panel to the display panel and driving it has a line address circuit for designating RAM and a line address of the RAM. The RAM regards the maximum gradation bit number as n1 (n1: an integer of 2 or more) and the designated gradation bit number as n2 (1≤n2≤n1) and stores display data of n2 by dividing it into 2k (k: 0 or a natural number) frames satisfying k=log
2 (n1/n2). The line address circuit generates the line address of M (M: an integer of 2 or more) bits corresponding to n1 and outputs a line lead address of the M bits offset in response to a frame address of k bits being an offset value.
