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

[0046] 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.

[0047] In order to solve the above problems, the present invention provides a pixel structure, including: a white light backplane for emitting white light, the surface of the white light backplane for emitting white light is the front side, and the front side of the white light backplane has a plurality of The white light sub-pixel layer provided, the white light sub-pixel layer is used to provide white light sub-pixels; the optical sensor located on the front of the white light backplane, the optical sensor is used to obtain the brightness of each white light sub-pixel; and the white light sub-pixel The optical filter arranged opposite to the front of the back plate, the optical filter includes a plurality of sub-pixel layers arranged side by side, and each sub-pixel laye...

Abstract

The invention discloses a pixel structure, a display screen and a method for adjusting luminance uniformity of the display screen. The pixel structure comprises a white-light backboard, an optical sensor and an optical filter, wherein the white-light backboard is used for emitting white light; the side, from which the white light is emitted, of the white-light backboard is regarded as a front side; a plurality of white-light sub-pixel layers, which are arranged side by side, are arranged on the front side of the white-light backboard, and the white-light sub-pixel layers are used for offeringwhite-light sub-pixels; the optical sensor is arranged on the front side of the white-light backboard; the optical sensor is used for acquiring luminance of the various white-light sub-pixels; the optical filter is arranged in a mode of being opposite to the front side of the white-light backboard; the optical filter comprises a plurality of sub-pixel layers which are arranged side by side; each sub-pixel layer is opposite to the position of each white-light sub-pixel layer; and the plurality of sub-pixel layers are different in color. According to the invention, the luminance uniformity of the display screen is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel structure, a display screen and a method for adjusting brightness uniformity of the display screen. Background technique [0002] In the production process of the existing OLED (Organic Light-Emitting Diode) display or micro LED display, there may be a serious problem of uneven brightness of the light-emitting point, so it is necessary to adjust the display brightness to deal with the uneven brightness . 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 the ...
