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 the way of connecting, to a compensation capacitor, at least one of the driving signal lines connected to each row of pixel circuits ina second display region, the loads of the driving signal lines connected with the compensation capacitors can be increased, the load difference with the driving signal lines in a first display regionis reduced, thus the uneven writing of data due to the different loads of the driving signal lines is improved, the problem of display unevenness is further alleviated, the compensation capacitors and the circuit units at least partially overlap in a direction perpendicular to the display panel, since the normal display of the display panel requires the arrangement of the circuit units in the display panel, the compensation capacitors are arranged to at least partially overlap with the circuit units in the direction perpendicular to the display panel, so that the compensation capacitors occupy the width of the frame of the display panel together with the circuit unit in steady of occupying the frame area of the display panel alone, and thus, the realization of the narrow frame design of the display panel is facilitated.

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...
