Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel compensation circuit, a driving method thereof, and a display device with the pixel compensation circuit. Background technique [0002] Compared with traditional liquid crystal displays, organic light-emitting display panels have the advantages of fast response, high contrast, brilliant colors, higher resistance to high and low extreme temperatures, and thinner and lighter weight. Therefore, they have gradually become the mainstream technology in the display field and are widely used in mobile phones, Tablet PCs, TVs, virtual reality, and more. [0003] Although the organic light-emitting display panel has the above-mentioned advantages, many problems arise during its application. For example, since the luminance of an organic light-emitting display device is related to the magnitude of the current flowing through the organic light-emitting display device, the e...
