Detailed Description

Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.

The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

In order to further improve the display effect of the display panel with the notch area, the inventors conducted the following studies on the display panel:

fig. 1 is a schematic structural view of a display panel, as shown in fig. 1, which includes a notch area NA ', a display area AA ', and a bezel area BA ' surrounding the display area AA ', wherein the bezel area BA ' includes a first bezel area BA1' and a second bezel area BA2' oppositely disposed in a first direction x ', and a portion of the first bezel area BA1' is recessed toward the display area AA ' to form the notch area NA '. The display panel further includes a first scan driving circuit SR1', a second scan driving circuit SR2', a plurality of scan lines S ' and a plurality of data lines D ', wherein the scan lines S ' extend along a first direction x ', the data lines D ' extend along a second direction y ', the first direction x ' intersects the second direction y ', the first scan driving circuit SR1' is disposed in the first frame area BA1', the second scan driving circuit SR2' is disposed in the second frame area BA2', the first scan driving circuit SR1' includes a plurality of sequentially cascaded first scan driving units SR1U ', the second scan driving circuit SR2' includes a plurality of sequentially cascaded second scan driving units SR2U ', the first scan driving unit SR1U ' and the second scan driving unit SR2U ' are connected to two ends of the scan lines S ', so as to implement dual-edge driving of the display panel.

Due to the arrangement of the gap area NA ', a portion of the data lines D ' may be blocked by the gap area NA ', and thus, the display panel is provided with two types of data lines D ', one is the first data line D1', the first data line D1' is wound around the frame area BA ' at the gap area NA ', and the other is the second data line D2 '.

As can be seen from fig. 1, in the frame area BA 'at the gap area NA', the first data line D1 'and the first scan driving circuit SR1' need to be disposed at the same time, so that the width of the frame area BA 'at the gap area NA' is wider, which affects the display effect of the display panel.

In order to solve the problem, a technical idea is to change a double-side driving mode of the display panel to a single-side driving mode, and the first scan driving circuit SR1 'is not disposed at the first frame area BA1', so that the frame area BA 'at the gap area NA' only needs to be disposed with the first data line D1', and the width of the frame area at the gap area NA' is reduced. However, in the one-side driving method, in order to avoid the thrust problem of the scan driving circuit of the one-side driving, the size of the electronic components in the scan driving circuit needs to be increased, so that the width of the second frame BA2 'in which the second scan driving circuit SR2' is disposed is increased. Therefore, the width of the frame area BA ' at the notch area NA ' is reduced by adopting the conventional technical idea, and the problem that the width of the frame area BA ' at the other side is increased is brought.

Based on the above technical research, the invention provides a display panel and a display device, which can realize unilateral driving in the display panel, and simultaneously divide a scanning driving unit driven in a scanning driving circuit into two module groups respectively arranged in two side frame areas, and only partial scanning driving units are arranged in the two side frame areas.
