DISPLAY DEVICE AND METHOD OF DRIVING THE SAME

摘要

In a display control circuit (60) of an RAM through type, RGB data generated based on a command conformed to the DSI standard transmitted from a host (1) is supplied to a checksum circuit (33). The checksum circuit (33) obtains a checksum value of the RGB data and determines whether the RGB data is updated or not based on the obtained checksum value. In the case where the RGB data is updated, the RGB data is supplied to a latch circuit (34) and checksum process data indicating that the RGB data is updated is supplied to a timing generator (35), thereby immediately forced-refreshing an image displayed in a display unit (15).

主权项

1. A display device comprising:
a display unit including a plurality of pixel formation portions each having a switching element and a pixel capacitance connected to the switching element; a drive circuit that drives the display unit; and a display control circuit that controls the drive circuit based on image data transmitted from the outside, wherein the display control circuit includes an image detection circuit that detects updating of an image expressed by the image data, and when updating of the image expressed by the image data is detected during a pause driving performed in predetermined cycles such that a refresh period for refreshing a screen of the display unit and a non-refresh period for pausing refreshing of the screen appear at a predetermined rate, the image detection circuit interrupts the pause driving and forcedly refreshes the screen of the display unit.
