Problems solved by technology

[0004] Since the display screen usually has a certain life span, it is difficult for each device in the display screen to attenuate at the same time as time goes by. The problem of unevenness will appear again

Embodiment Construction

[0043] It can be seen from the background art that it is urgent to provide a dynamic brightness uniformity adjustment method to obtain the display status of the display screen in real time for compensation.

[0044] In order to solve the above problems, the present invention provides a pixel structure, an RGB backplane for emitting colored light, the side of the RGB backplane for emitting colored light is the front, and the front of the RGB backplane has three pixels arranged in sequence. A light-emitting material layer, including a red light-emitting material layer, a green light-emitting material layer and a blue light-emitting material layer, the red light-emitting material layer is used to provide red sub-pixels, the green light-emitting material layer is used to provide green sub-pixels, the The blue luminescent material layer is used to provide blue sub-pixels; the optical sensor located on the front of the RGB backplane is used to obtain the brightness of the red sub-pix...

Abstract

The present invention provides a pixel structure, a display screen and a method for regulation of brightness uniformity of a display screen. The pixel structure comprises: a RGB backboard configured to emit colorful light, wherein a surface, emitting the colorful light, of the RGB backboard is a front surface, the front surface of the RGB backboard has three luminescent material layers arranged inorder, the three luminescent material layers comprise a red luminescent material layer, a green luminescent material layer and a blue luminescent material layer, the red luminescent material layer isconfigured to provide red subpixels, the green luminescent material layer is configured to provide green subpixels, and the blue luminescent material layer is configured to provide blue subpixels; and an optical sensor located at the front surface of the RGB backboard and configured to obtain the brightness of the red subpixels, the brightness of the green subpixels and the brightness of the bluesubpixels. The brightness uniformity of the display screen is improved.

Description

technical field [0001] The invention relates to the field of display technology, and particularly designs a pixel structure, a display screen and a method for adjusting brightness uniformity of the display screen. Background technique [0002] During the production process of the existing OLED (Organic Light-Emitting Diode) display or micro LED display, there may be a relatively serious problem of uneven brightness of the light-emitting point, so it is necessary to adjust the uneven brightness of the display. . For adjusting the uniformity of the brightness of the display screen, there are usually the following three methods: a voltage compensation circuit type, a current compensation circuit type, and a device optical supplementary type. [0003] Specifically, the voltage compensation circuit type uses 7 MOS tubes to realize voltage compensation through positive and negative voltage drops to ensure that the display screen is in a state of uniform brightness; however, for t...
