METHOD OF DRIVING ELECTROOPTIC DEVICE, ELECTROOPTIC DEVICE AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To surely prevent appearance of unevenness (longitudinal streak) in a boundary between adjacent display areas corresponding to the respective ICs in driving an electrooptic device using a plurality of driving ICs. SOLUTION: A first gradation voltage generating circuit 110a of a first driving IC 10 performs generation of gradation voltage using a first power supply voltage VA and generation of gradation voltage using a second power supply voltage VB received by a first power supply voltage receiving terminal VRin alternately in a predetermined cycle. A second gradation voltage generating circuit 110b of a second driving IC 20 performs generation of gradation voltage using the second power supply voltage VB and generation of gradation voltage using the first power supply voltage VA received by a second power supply voltage receiving terminal VLin alternately in the above predetermined cycle. The predetermined cycle is set to a cycle shorter not to be recognized by vision of human being. COPYRIGHT: (C)2011,JPO&INPIT
