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 herein 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, the drawings only show some but not all structures related to the present invention.

[0038] At the same time, the drawings and descriptions of the embodiments are illustrative rather than restrictive. The same reference numbers refer to the same elements throughout the specification. Additionally, the thickness of some layers, films, panels, regions, etc., may be exaggerated in the drawings for understanding and ease of description. It will also 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 int...

Abstract

The invention discloses a method for improving color shift, a display panel and a display device. The display panel includes: a pixel defining layer arranged on a base substrate, the pixel defining layer comprising a separator and a plurality of opening regions for accommodating sub-pixel units; at least one photosensitive device arranged on the separator, the photosensitive device is used for It collects the optical signal emitted by the sub-pixel unit, converts the optical signal into an electrical signal and sends it to the IC chip of the display panel, so that the IC chip can adjust the brightness of the sub-pixel unit. The display panel can adjust the brightness of light of different colors, so as to improve the problem of low gray-scale color cast after the high-temperature reliability test of the display panel.

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 (OLED) display technology is a very promising display technology. The organic light-emitting display panel produced by this technology has self-luminous, ultra-thin, wide viewing angle, fast response speed and low power consumption. The advantages of low power consumption and flexible display are widely used in the display field. [0003] The organic light-emitting display panel will appear low gray-scale color shift after high temperature reliability test. The existing solution is to change the host material / guest material of the light-emitting layer, or adjust the thickness / doping ratio of the light-emitting layer to improve this. questionable. However, the existing solutions cannot completely solve the problem of lo...
