Abstract

The invention relates to the field of display technology, and provides a display substrate and a preparation method thereof, a display panel, and a display device. The preparation method of the display substrate includes: forming an optical compensation control thin film transistor on one side of the base substrate; forming a conductor protection layer on the side of the optical compensation control thin film transistor away from the base substrate; Form an optical detection device material layer on one side; pattern the optical detection device material layer to form an optical detection device, and pattern the conductor protection layer to form a conductor pattern; wherein, the optical detection device controls the source of the thin film transistor through the conductor pattern and optical compensation pole or drain electrical connection. After using this method, the display effect of the display panel is better.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display substrate and a method for preparing the display substrate, a display panel mounted with the display substrate, and a display device mounted with the display panel. Background technique [0002] An organic light emitting diode (English: Organic light emitting diode; OLED for short) display panel is a new type of display panel on the market. Compared with liquid crystal display panels, OLED display panels have many advantages such as wide color gamut, high contrast ratio, and ultra-thinness due to the self-luminous properties of OLED display panels. [0003] Since the OLED display panel works in a state of high contrast and high brightness for a long time, the luminous brightness of the organic light-emitting layers in each sub-pixel in the OLED display panel is inconsistent, which will cause the OLED display panel to emit unevenly. The sub-pixels in the d...
