Abstract

The embodiment of the invention provides a pixel circuit, an array substrate, a display panel and electronic equipment. The pixel circuit comprises a data writing-in unit, a first data storage unit, asecond data storage unit and a light-emitting control unit. The data writing-in unit writes data signals of the data signal input end into the first data storage unit under control of input signals of the first control signal input end and writes the data signals of the data signal input end into the second data storage unit under control of input signals of the second control signal input end. The light-emitting control unit controls connecting and disconnecting of corresponding thin film transistors by referring to the data signals output through the first data storage unit and the second data storage unit, accordingly, different gray values are presented, compared with an existing pixel circuit, the more gray values can be presented, and the current requirement of industry for high definition is met.

Description

technical field [0001] The present application relates to the field of display technology, in particular, the present application relates to a pixel circuit, an array substrate, a display panel and electronic equipment. Background technique [0002] If an animated image or a static image is input to the liquid crystal display panel, the voltage of the data signal of the input image will be input into each sub-pixel during each frame, and displayed. Since data signals are input to each sub-pixel in each frame, the power consumption of the source driving circuit and the gate driving circuit cannot be reduced below a certain level. [0003] In order to reduce the power consumption of the liquid crystal display panel, MIP (memoryin pixel, in-pixel memory) technology is currently proposed. The MIP technology is to set a circuit containing a storage unit in each sub-pixel. When a static image is input, the source drive circuit In the disabled state, the data signal is re-input th...
