example 1

[0147]With the development direction of high frame rate and high resolution of OLED display screen, the power consumption is also rising. The existing method of dynamically adjusting ELVSS to reduce power consumption is to dynamically adjust the ELVSS voltage according to the display content, thereby reducing the difference between ELVDD and ELVSS. The voltage difference between them (hereinafter referred to as △EL=ELVDD-ELVSS=Vdtft+Vdiode) to reduce power consumption, but this method will greatly affect the display effect, because if figure 1 , the Dtft triode characteristics of each pixel are different due to the process deviation of each display screen. When encountering a display screen with a large difference in the Dtft triode characteristics of each pixel, the brightness will become darker and the Mura will become heavier if the △EL is reduced. The reason is that according to the output characteristic curve of the triode, the worse the performance of the triode needs a b...

Abstract

The invention relates to an OLED display screen display control method and device and a storage medium. The OLED display screen display control method comprises the following steps: acquiring optical compensation data of uneven brightness of a display screen; comparing the optical compensation data with a preset threshold value; when the optical compensation data is smaller than the preset threshold value, under the condition that a controlled switch of a pixel unit of the OLED display screen works in a saturation region range, decreasing the driving voltage of the pixel unit in the OLED display screen, wherein the reduced driving voltage is used for controlling the phenomenon of uneven brightness caused by display of the pixel unit, and the display effect is improved; and the display of the pixel units is controlled by the reduced driving voltage, so that the display power consumption can be reduced.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a display control method and device for an OLED display, and a storage medium. Background technique [0002] The display screen includes a pixel array, and a pixel array includes a plurality of pixel units. Whether the pixel units emit light or not, and the light emitted by the pixel units of different colors, provides a display of various colors through the phenomenon of light mixing. [0003] However, with the development of display technologies, high frame rate displays appear, for example, high frame rate displays up to 120 Hz. The higher the frame rate, the higher the power consumption generated by the display. [0004] Various display methods for reducing display power consumption have been proposed in the related art. However, in some cases, it is found that the brightness of the display is uneven (mura) in these display methods that reduce power consumpti...
