Embodiment Construction

[0071] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe in detail the embodiments of the present invention in conjunction with the accompanying drawings.

[0072] The transistors used in all the embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics, and the transistors used in the embodiments of the present invention are mainly switching transistors according to their functions in circuits. Since the source and drain of the switching transistor used here are symmetrical, the source and drain are interchangeable. In the embodiments of the present invention, the source is called the first pole, and the drain is called the second pole; or, the drain is called the first pole, and the source is called the second pole. According to the form in the accompanying drawings, it is stipulated that the middle terminal of...

Abstract

The invention discloses a pixel circuit, a display substrate, a display device and a driving method. The pixel circuit comprises a data writing sub-circuit and a driving sub-circuit, the data writingsub-circuit is connected with a scanning signal end, a control signal end, a data signal end and the driving sub-circuit. The data writing sub-circuit needs to respond to a scanning signal provided bythe scanning signal end and a control signal provided by the control signal end to output the data signal to the driving sub-circuit, so that the potential of the control signal provided by the control signal end can be controlled, the pixel circuit only located in the area of the to-be-refreshed image drives the light-emitting element connected with the pixel circuit to emit light, and the imagerefreshing of the local area is further realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel circuit, a display substrate, a display device and a driving method. Background technique [0002] Organic light emitting diodes (organic light emitting diodes, OLEDs) are widely used in high-performance display substrates due to their advantages of thinness, light emission, high contrast ratio, and wide operating temperature range. [0003] In the related art, an OLED display substrate includes a plurality of gate lines, a plurality of data lines and a plurality of pixel units, and each pixel unit includes a pixel circuit and a light emitting element. Each gate line is connected to a row of pixel units, and each data line is connected to a column of pixel units. The pixel circuit in each pixel unit can respond to the gate driving signal provided by the gate line, and drive the light emitting element connected to it to emit light according to the data signal provided by...
