ABSTRACT:
A display provided to reduce flicker by a driving method of using a sub field drive.One field is divided into plural sub fields on a time axis, each of which is a control unit to drive a pixel. A code storing ROM stores a code to give a sub field drive pattern based on display data. With respect to adjacent pixels within a control area, a data encoder writes pixel data by using a sub field drive pattern read from the code storing ROM and a pattern delayed by the predetermined sub field period. Hence, adjacent pixels are driven by different sub fields drive patterns each other so that timing of flickering among adjacent pixels is differentiated.
