Embodiment Construction
[0048]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0049] As mentioned in the background art, in actual use, it is found that organic light-emitting diode displays have non-uniform light emission. Specifically, refer to figure 1 Shown is a circuit diagram of an existing pixel circuit in an organic light emitting diode display. Most of the existing pixel circuits adopt a 2T1C structure, that is, include two transistors and a capacitor. Wherein, the transistor M20 is used as a current driving transistor to provi...
