DISPLAY DEVICE AND DRIVE METHOD FOR SAME

摘要

In the present invention, a display device having data signal lines driven by a plurality of driver ICs is made such that even when pause drive is carried out, display offsetting during image refreshing and other abnormalities do not arise. Provided is a liquid crystal display device wherein a master IC (300L) sends a refresh control signal (RfC) to a slave IC (300R) if the master IC detects a refresh initiation timing by REF (Half) thereof, or sends a refresh control signal (RfC) to the slave IC (300R) if the master IC receives a refresh detection signal (RfD) indicating the refresh initiation timing detected by the REF (Half) of the slave IC (300R), and also initiates refreshing for a left active area on the basis of data within 1/2 RAM (306L). The slave IC (300R) initiates refreshing for a right active area on the basis of data within 1/2 RAM (306R) if the slave IC receives the refresh control signal (RfC).
