Abstract

The invention provides an OLED pixel and a drive circuit and method of the OLED pixel. The OLED pixel comprises three sub-pixel units. Each sub-pixel unit comprises two sub-pixels, wherein the area ratio of the two sub-pixels is 2:1. Each sub-pixel unit is driven by two gate electrode wires. The drive circuit of the OLED pixel is a simple circuit of a 2T1C structure, and multiple colors can be achieved by controlling drive current of the gate electrode wires. The OLED pixel and the drive circuit and method of the OLED pixel have the advantages that no compensation circuit is required, the complexity of the drive circuit and the overall cost are lowered, and the yield of the drive circuit is improved; meanwhile, each OLED pixel at least can achieve 4,096 colors by controlling drive scanning frequency and the drive current of the gate electrode wires.

Description

technical field [0001] The invention belongs to the technical field of semiconductors, and in particular relates to an OLED pixel, a driving circuit and a driving method of the pixel. Background technique [0002] The OLED display technology has the characteristic of self-luminescence, and the viewing angle of the OLED display screen is large, and it can save power, so the OLED is widely used in fields such as panel display. Existing OLED drivers use compensation circuits, which complicates the driving circuit and reduces yield. Moreover, OLED drivers are all analog drivers, resulting in an increase in the overall cost. [0003] Therefore, while improving the yield rate of the driving circuit, it is urgent to reduce the cost and simplify the complexity of the driving circuit. Contents of the invention [0004] To solve the above problems, the object of the present invention is to provide an OLED pixel, a driving circuit and a driving method for the pixel. [0005] The p...
