Document Type and Number:
WIPO Patent Application WO/2018/205321
Kind Code:
A1
Abstract:
A display device and a power saving method therefor, the display device comprising: a display panel (10, 120); a plurality of data driving chips (30, 116), which are electrically connected to the display panel; a plurality of gate driving chips (40, 118), which are electrically connected to the display panel; a power source chip (320), which is electrically connected to the data driving chips and the gate driving chips respectively so as to control the power supply to the data driving chips and the gate driving chips; a display data detection unit (310) used to detect the data driving chips so as to generate a control signal; and a time sequence controller (110), which is electrically connected to the data driving chips, the gate driving chips, the power supply chip and the display data detection unit respectively so as to control the operations thereof. The time sequence controller receives the control signal from the display data detection unit and controls whether the data driving chips, the gate driving chips and the power supply chip enter a power saving mode or not on the basis of the control signal, wherein the power saving mode indicates reducing the normal voltage to a preset update voltage.
