COMMON VOLTAGE ADJUSTMENT CIRCUIT AND METHOD, DISPLAY DRIVER CIRCUIT, DISPLAY APPARATUS

摘要

Provided are a common voltage adjustment circuit and a method thereof, a display driver circuit and a display apparatus, the common voltage adjustment circuit being used in a display panel, and the display panel comprising: a pixel electrode and a common electrode, and the common voltage adjustment circuit comprising: a first adjustment sub-circuit, used to provide a signal of a second signal input terminal (INPUT2) to a first signal output terminal (OUTPUT1) under control of an enabling signal terminal (EN) when the display panel is in a startup phase; a first signal input terminal (INPUT1) being configured to be used to input a signal provided to the common electrode during a display phase of the display panel, the second signal input terminal (INPUT2) being configured to be used to input a signal provided to the pixel electrode when the display panel is in a startup phase, and the first signal output terminal (OUTPUT1) being connected to the common electrode. It is possible to prevent startup ghosting caused by a difference in voltage between a signal of a common electrode and a signal of a pixel electrode, improving display results of a display panel.
