Embodiment 2

[0070] This embodiment provides a display method, which is applied to the display substrate according to Embodiment 1 of the present invention. The display methods include:

[0071] Step 1: Obtain the display detection data of the first type of light-emitting diodes and the corresponding expected light intensity of the light passing through the light-transmitting region 112 .

[0072] The display detection data is derived from the image data that the display substrate needs to display. The image data at this time may correspond to a specific detection image, or may correspond to any display image. The coordinates of the first type of light-emitting diodes are determined, so that the display detection data of the first type of light-emitting diodes can be obtained from the image data, and of course, the light intensity of the first type of light-emitting diodes passing through the light-transmitting area 112 can also be known. Expected light intensity.

[0073] Step 2: Drive...

Embodiment 3

Abstract

The invention provides a display substrate, a display method and a display device, which belong to the technical field of display, and can at least partially solve the problem that the uniformity of the color and the brightness of an existing light-emitting diode type display device is poor along with time. The display substrate comprises a reflection structure and a plurality of light-emitting diodes, wherein the reflection structure has a light reflection area; the light reflection area is used for reflecting light emitted by the light-emitting diodes in a first direction to be displayed; the reflection structure further has a light-transmitting area; at least part of the light-emitting diodes are first light-emitting diodes; part of light emitted by the first light-emitting diodes can penetrate through the light-transmitting area; and the light penetrating through the light-transmitting area is used for detecting the light intensity of the first light-emitting diodes.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display substrate, a display method and a display device. Background technique [0002] The light-emitting elements in one type of existing display devices are light-emitting diodes, including organic light-emitting diodes (OLEDs) and inorganic micro-light-emitting diodes (Micro LEDs). With the passage of time, each light emitting diode will age, and the degree of aging is different. In addition, the threshold voltage of each light emitting diode will also drift, and the degree of drift is also different. This results in non-uniform colors and brightness displayed by the display device. Contents of the invention [0003] The present invention at least partly solves the problem of non-uniform color and brightness over time of use of existing light-emitting diode display devices, and provides a display substrate, a display method and a display device. [0004] Ac...
