The present disclosure relates to a pixel circuit, a driving method thereof, and a display device. The pixel circuit includes: a first output module, including a first output terminal and a second output terminal, for selecting the first output in response to a first data signal terminal or the second output terminal to output the second data signal; the first selection control module is used to output the first selection control signal in response to the signal output by the first output terminal of the first output module; the second selection control module is used to output the first selection control signal outputting a second selection control signal in response to a signal output from the second output terminal of the first output module; the first selection module is configured to select and output the first voltage signal or the second voltage signal to the first node in response to the first selection control signal; The second selection module is used to select and output the third voltage signal or the fourth voltage signal to the second node in response to the second selection control signal; the third selection module is used to select and output the first node or the first node in response to the first data signal. Two-node voltage signal.
Description
technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a pixel circuit, a driving method thereof, and a display device. Background technique [0002] With the development and progress of technology, more and more devices need to be equipped with display devices, and in some application scenarios, the power consumption requirements of the display devices are relatively strict, for example, wearable display terminals. In a display device, reducing the refresh frequency can effectively reduce the operating power consumption. [0003] At present, the data signal can be latched by adding a memory unit (MIP, Memory In Pixel) circuit in the pixel circuit, thereby reducing the refresh frequency of the data signal, but the MIP circuit in the related art can only output two levels signal, that is, each sub-pixel has only two gray-scale voltages, so that the display device can display fewer colors, resulting in poor display qual...
