Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0038] Meanwhile, the drawings and descriptions of the embodiments are illustrative rather than restrictive. Like reference numerals refer to like elements throughout the specification. Also, for understanding and ease of description, the thickness of some layers, films, panels, regions, etc. may be exaggerated in the drawings. Also, it will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or interv...

Abstract

The invention discloses a method for improving color cast, a display panel and a display device. The display panel comprises a pixel limiting layer which is arranged on an underlayment substrate and comprises separation bodies and a plurality of opening areas used for accommodating sub-pixel units, and at least one photosensitive device which is arranged on the separation bodies and is used for collecting optical signals sent by the sub-pixel units, converting the optical signals into electrical signals and sending the electrical signals to an IC chip of the display panel to enable the IC chipto adjust the brightness of the sub-pixel units. According to the display panel, the brightness of light of different colors can be adjusted, and the problem of low grayscale color cast of the display panel after high-temperature reliability test is solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method for improving color shift, a display panel, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display technology is a display technology with great development prospects. The organic light-emitting display panel produced by this technology has the characteristics of self-illumination, ultra-thin, wide viewing angle, fast response speed, and low power consumption. It is widely used in the field of display due to its advantages of low power consumption and flexible display. [0003] Organic light-emitting display panels will experience low grayscale color shift after high-temperature reliability tests. The existing solutions are to improve this by changing the host material / guest material of the light-emitting layer, or adjusting the thickness / doping ratio of the light-emitting ...
