Problems solved by technology

[0003] However, for electronic display products using organic light-emitting diode technology, they are highly dependent on temperature. Under the same driving voltage, their brightness will change with temperature. Therefore, when the ambient temperature changes, OLED display will produce color cast. As a result, the display image of the electronic display product is distorted and the user experience is reduced.

Embodiment Construction

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0047]The display area of ​​the display substrate is distributed with a plurality of pixels (which can be called large pixels), which can emit light of different colors and different brightness. Each pixel includes multiple sub-pixels (which can be called sub-pixels), and each sub-pixel emits light For light of a specific color, the light-emitting brightness of each sub-pixel can be adjusted. By adjusting the light-emitting b...

Abstract

The invention provides a display substrate and a display panel. The display substrate comprises a substrate, a pixel defining layer, a plurality of light emitting devices and an expansion layer. The pixel defining layer is located on the substrate and comprises a plurality of openings. A plurality of light emitting devices are defined in the opening, and a portion of the plurality of light emitting devices are color cast light emitting devices. The expansion layer is located on the side, away from the substrate, of the pixel defining layer, and at least part of the expansion layer surrounds and defines an opening of the color-cast light-emitting device. At a high temperature, the expansion layer expands to shield the emergent light of the color cast light-emitting device, so that the emergent light brightness of the sub-pixel corresponding to the color cast light-emitting device is reduced, and the high-temperature color cast problem of the display substrate and the display panel is relieved or eliminated.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display substrate and a display panel having the display substrate. Background technique [0002] Organic Light-Emitting Diode (OLED) has many advantages such as simple preparation process, low cost, low power consumption, high brightness, wide viewing angle, high contrast ratio and flexible display, so it is widely used in various electronic display products. . [0003] However, for electronic display products using organic light emitting diode technology, the temperature dependence is high. Under the same driving voltage, the brightness will change with the temperature change. Therefore, when the ambient temperature changes, the OLED display will produce color cast, As a result, the display image of the electronic display product is distorted, and the user experience is reduced. SUMMARY OF THE INVENTION [0004] A first aspect of the present application pr...
