Display panel, display device and reference voltage value determination method and device

Abstract

The invention discloses a display panel, a display device and a reference voltage value determining method and device. The display panel is provided with a first display area and a second display area, the light transmittance of the first display area is larger than that of the second display area, and the display panel comprises a first pixel circuit electrically connected with a first sub-pixelof the first display area and a second pixel circuit electrically connected with a second sub-pixel of the second display area. The second pixel circuit is electrically connected with the second sub-pixel of the second display area; the plurality of reference voltage signal lines extend along the first direction and are distributed at intervals in a second direction intersected with the first direction; wherein the reference voltage signal lines comprise a first reference voltage signal line and a second reference voltage signal line, the first reference voltage signal line is electrically connected with the first pixel circuit and the first level voltage end, and the second reference voltage signal line is electrically connected with the second pixel circuit and the second level voltage end. According to the display panel provided by the embodiment of the invention, the display uniformity of the display panel can be improved.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel, a display device, a method for determining a reference voltage value of the display panel, and a device for determining the reference voltage value of the display panel. Background technique [0002] With the rapid development of electronic devices, users have higher and higher requirements for screen-to-body ratio, so that the full-screen display of electronic devices has attracted more and more attention from the industry. [0003] On electronic devices such as mobile phones and tablet computers, photosensitive components such as front cameras, infrared light sensors, and proximity light sensors need to be integrated on one side of the display panel. In some embodiments, a light-transmitting display area may be provided on the above-mentioned electronic device, and a photosensitive component may be arranged on the back of the light-transmitting display area, so as t...

AI Technical Summary

Problems solved by technology

[0004] However, due to structural differences between the light-transmitting display area corresponding to the photosensitive component and other display areas, the uniformity of display in different areas of the display panel is affected.
