Embodiment 1

[0045] like figure 1 As shown, the method for reducing display power consumption provided by this embodiment includes the following steps:

[0046] S1: calculate multiple average color level values ​​ARL, AGL, ABL of multiple sub-pixel input data of the display screen of the display;

[0047] Specifically, such as figure 2 As shown, the specific method for realizing the step S1 includes the following steps:

[0048] S101: Extract input data of a plurality of sub-pixel RGB respectively, the sub-pixel input data of the display screen includes the input data of the sub-pixel RGB;

[0049]In step S101 , since the display picture seen by human eyes on the display panel is composed of pixels, each pixel is composed of three sub-pixels of red R, green G, and blue B. Therefore, when the sub-pixel input data is input data of a plurality of sub-pixel RGB, the input data of a plurality of sub-pixel RGB of the display screen can be extracted as R(i, j), G(i ,j), B(i,j). Since the wh...

Embodiment 2

[0070] like Figure 8 As shown, this embodiment provides a device 100 for reducing power consumption of a display, including an average color level calculation module 10 , an average image level calculation module 20 , a brightness adjustment value output module 30 , and a brightness adjustment module 40 .

[0071] The average color level calculation module 10 is configured to obtain the average color level value of a plurality of sub-pixel input data of the display screen of the display, wherein the average color level calculation module 10 includes a sub-pixel input data extraction unit 101, Sub-pixel luminance data calculation unit 102, sub-pixel average color level calculation unit 103;

[0072] The average image level calculation module 20 is configured to calculate the average image level value of the display picture according to the average color level value of the sub-pixel data of the display picture;

[0073] The brightness adjustment value output module 30 is confi...

Abstract

The invention provides a method and device for reducing the power consumption of a display. The method comprises the following steps of S1, calculating to obtain the average color level values ARL, AGL and ABL of a plurality of sub-pixel input data of a display picture of the display; s2, calculating according to the average color level values ARL, AGL and ABL to obtain an average image level value APL of the display image; s3, outputting a brightness adjustment value according to the average image level APL value of the display image; and S4 adjusting the display brightness of the display image according to the brightness adjustment value, calculating to obtain an average image level APL value of a display picture by using the brightness information of the sub-pixels R, G and B, and adjusting the brightness according to the APL value, so that the detail loss caused by the fact that the dark part details are not prone to being shown when the brightness adjustment is carried out throughgray scale information is solved, the color information of all the sub-pixels is reserved, the image details are richer, and the layer of the image is clearer.

Description

technical field [0001] The disclosure relates to the field of display technology, and in particular to a method and device for reducing power consumption of a display. Background technique [0002] Displays such as OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) displays are increasingly important in the display field because of their wider viewing angle, higher refresh rate and thinner thickness. However, when the average image level of the image displayed by the OLED display increases, which means that the pixel display grayscale increases, as the pixel display grayscale increases, the current flowing through the organic light-emitting diode of the pixel increases, thus causing the power of the organic light-emitting diode to increase. Consumption increases. [0003] The traditional method of reducing the power consumption of organic light-emitting diodes usually uses the Max(R, G, B) method, that is, the maximum value of the gray scale value of the sub-...
