Abstract

The invention discloses a display compensation circuit, a display substrate, a display device and a driving method, and belongs to the field of display technology. The display compensation circuit includes: a switch subcircuit; each of the switch subcircuits has an input terminal, an output terminal and a control terminal; the output terminal of the switch subcircuit is electrically connected to one of the first common electrodes; the switch subcircuit The circuit is configured to be turned on under the control of the control signal received by the control terminal, and to provide the compensation voltage signal received by the input terminal to the corresponding first common electrode when it is turned on. The display uniformity problem caused by the load difference between the first common electrode and the second common electrode is solved.

Description

technical field

[0001] The present invention relates to the field of display technology, and in particular, to a display compensation circuit, a display substrate, a display device and a driving method. Background technique

[0002] With the technological development of mobile terminals, the screen ratio of mobile terminals is increasing. When the screen ratio of the mobile terminal reaches a certain size, a slot or a hole needs to be formed on the screen of the mobile terminal to set the front camera.

[0003] For touch screens and other screens that divide the common electrodes into multiple common electrodes for function multiplexing, since most of the slots or holes on the screen where the front camera is set are U-shaped or circular, when the screen is fabricated, the holes or holes located in the slots or holes are mostly U-shaped or circular. The nearby common electrode needs to be shaped to match the shape of the slot or hole.

[0004] Compared with the normal comm...
