Problems solved by technology

[0002] In the pixel circuit of an organic light emitting diode (OLED) display, due to process factors, the transistors in each pixel circuit may have different threshold voltages, resulting in inconsistent currents driving the organic light emitting diodes, resulting in uneven brightness of the display. average problem
However, the traditional pixel compensation circuit requires too many components and requires a long compensation time, so the compensation effect is very limited

Abstract

A display device includes a compensation signal line, a plurality of drive circuits and a plurality of pixel circuits. The drive circuits are coupled to the compensation signal line. The compensationsignal line is used for providing compensation signals. A first drive circuit of the drive circuits is used for receiving the compensation signals and outputting the compensation signals according toa first control signal. A first pixel circuit of the pixel circuits includes an OLED and is used for receiving the compensation signals and data signals, and adjusting current volume flowing through the OLED according to the compensation signals and the data signals.

Description

technical field [0001] The disclosure is a display technology, and particularly relates to a display device. Background technique [0002] In the pixel circuit of an organic light emitting diode (OLED) display, due to process factors, the transistors in each pixel circuit may have different threshold voltages, resulting in inconsistent currents driving the organic light emitting diodes, resulting in uneven brightness of the display. average problem. However, the traditional pixel compensation circuit requires too many components and requires a long compensation time, so the compensation effect is very limited. Contents of the invention [0003] An aspect of the present disclosure is a display device including a compensation signal line, a plurality of driving circuits, and a plurality of pixel circuits. The driving circuit is coupled to the compensation signal line. The compensation signal line is used for providing compensation signals. The first driving circuit of th...
