Abstract

The invention provides a display substrate, a display panel and a manufacturing method of the display substrate. The display substrate comprises a substrate body and a metal shading layer located on the substrate body. The first thin film transistor, the photodiode and the second thin film transistor are positioned on the metal shading layer; wherein the output end of the first thin film transistor is electrically connected with the pixel electrode, the photodiode comprises a first electrode, a second electrode and a photosensitive layer, the second electrode of the photodiode is connected with the second thin film transistor, and photocurrent generated by the photodiode is sent to the second thin film transistor; the output end of the first thin film transistor is electrically connected with the metal shading layer, and the grid electrode of the first thin film transistor is electrically connected with the first electrode. Due to the fact that the first electrode is connected with thegrid electrode of the first thin film transistor, and the metal shading layer is electrically connected with the source electrode of the first thin film transistor, different voltages of the upper layer and the lower layer of the double-grid structure are achieved, the influence of hydrogen on a lower-layer channel region is reduced, and the array backboard with good characteristics can be obtained.

Description

technical field [0001] The invention relates to the display field, in particular to a display substrate, a display panel and a method for manufacturing the display substrate. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display technology has the advantages of low power consumption, fast response, wide viewing angle, thin thickness, and flexibility. Currently, OLED displays have been widely used. In order to improve the display effect of the OLED display panel, it is necessary to compensate the OLED display panel according to the display state. The commonly used compensation method is electrical compensation, but the effect of electrical compensation is very limited, and it is difficult to further improve the display effect. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a display substrate, a display panel, and a method for manufacturing a displ...
