Embodiment Construction

[0041] In order to achieve full screen display, such as Figure 2a with Figure 2b as shown, Figure 2a with Figure 2b They are schematic structural diagrams of the display panels provided by the embodiments of the present invention; generally, devices such as a camera and an earpiece are arranged in the middle area A of the display panel, so that the number of pixels in a row of pixels in the first display area B1 of the display panel will be less than The number of pixels in a row of pixels in the second display area B2 is large, wherein the second display area B2 is divided into a first sub-area B21, a second sub-area B22 and an intermediate area A, and the first sub-area B21 and the second sub-area B22 are divided into The middle area A is arranged at intervals, resulting in different loads on the driving signal lines connected to the pixels in the first display area B1 and in the second display area B2, resulting in uneven data writing and display unevenness. In addit...

Abstract

The invention discloses a display panel and a display device. By connecting at least one of the driving signal lines connected to each row of pixel circuits in a second display area to a compensation capacitor, the driving force for connecting the compensation capacitor can be increased. The load of the signal line reduces the load gap with the driving signal line in the first display area, thereby improving the uneven data writing due to the different load of the driving signal line, thereby alleviating the problem of uneven display, and compensating the capacitor and the circuit unit Overlap at least partially in the direction perpendicular to the display panel. Since the display panel must be provided with circuit units to drive the normal display of the display panel, the compensation capacitor is set to at least partially overlap with the circuit unit in the direction perpendicular to the display panel, thereby compensating The capacitor does not need to occupy the frame area of ​​the display panel alone, but occupies the width of the frame of the display panel together with the circuit unit, thereby facilitating the realization of a narrow frame design of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of display technology, the full screen has a large screen-to-body ratio and an ultra-narrow bezel. Compared with ordinary display screens, it can greatly improve the visual effect of the viewer, and thus has received widespread attention. At present, in a display device with a full screen such as a mobile phone, in order to realize the functions of Selfie, video call and fingerprint recognition, a front camera, an earpiece, a fingerprint recognition area or physical buttons are usually arranged on the front of the display device. Such as figure 1 As shown in the structural diagram of the display panel, the front camera 10, the earpiece 20, etc. are generally arranged in the uppermost non-display area of ​​the display panel, and the fingerprint identification or physical buttons 30 are gener...
