Problems solved by technology

[0004] In order to integrate more functions of electronic equipment, it is necessary to set slots on the display panel for setting functional electronic components. For example, in the display panel of an existing smartphone, the upper end needs to be set for the receiver and camera slots, and the lower end needs to be set It is used to set the slot of the fingerprint sensor, which will lead to the change of the load of the gate line, so that the charging voltage of the pixel electrode will deviate, which will affect the image display quality of the display panel

Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] As mentioned in the background art, in order to integrate more functions in electronic devices, it is necessary to provide slots on the display panel for arranging functional electronic components and / or multiplex the components in the display panel that perform the first function to perform the second function.

[0044] refer to Figure 1-Figure 3 , figure 1 It is a top view of a common low-screen-to-body ratio mobile phone in the prior art, and FIG. ...

Abstract

The present invention discloses a display panel and a control method. The display panel has a first display area and a second display area; first gate lines in the first display area and second gate lines in the second display area have different loads. In the display phase, common electrodes located in the first display area and common electrodes located in the second display area respectively receive different common voltages, so that data signals of pixel electrodes do not need to be changed, different common voltages are provided for the common electrodes to solve the problem of poor imagequality due to the deviation of the charging voltages of the pixel electrodes, and the image display quality of the display panel is improved.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a display panel and a control method. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work. essential tool. [0003] The main component of an electronic device to realize a display function is a display panel. The liquid crystal display panel is a mainstream display panel at the present stage. When performing display driving, the common electrode of the pixel unit inputs a common voltage, and it is necessary to turn on the thin film transistor of the pixel unit through the gate line, so as to charge the pixel electrode of the pixel unit through the data line, and control the pixel through the electric field of the common electrode and the pixel electrod...
