Abstract

The invention discloses a method for reducing power consumption of a display panel. The method comprises a display panel providing step, a current picture brightness counting step, a static picture judging step and an energy-saving adjusting step. A brightness adjustment coefficient corresponding to a current picture is obtained through brightness statistical information, and target brightness operation of the current picture is carried out through the brightness adjustment coefficient to obtain the adjusted picture with reduced brightness, so that the purposes of good energy-saving effect andgood display quality can be achieved.

Description

technical field [0001] The present invention relates to a method for reducing power consumption, in particular to a method and device for reducing power consumption of a display panel, which can maintain the display quality of a display screen while reducing the power consumption of an organic light emitting diode display panel. Background technique [0002] In order to improve the lifespan of an organic light emitting diode (Organic Light Emitting Diode, OLED) display panel, there is an existing energy-saving (Economy, ECO) algorithm. After the OLED display panel displays a static image for a period of time, the OLED display device will enter the energy-saving mode ( ECO Mode) to automatically reduce the brightness of the display screen. [0003] Please refer to figure 1 and figure 2 , figure 1 It is a line graph of the energy-saving rate and time of the existing energy-saving method of the display panel, wherein eco_target is the brightness adjustment coefficient (targ...
