Example Embodiment

[0040]下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。

[0041]正如背景技术所述，现有显示装置存在屏下摄像头区域的大小受限，以及屏下摄像头区域和正常显示区域的显示画面存在差异的技术问题。经发明人研究发现，出现上述问题的原因如下：现有显示装置通常将摄像头放置于屏幕下方，为避免影响摄像头的成像质量，将屏幕划分为透明显示区域(屏下摄像头区域)和正常显示区域。透明显示区域的下方放置摄像头，透明显示区域与正常显示区域单独驱动，独立显示。现有技术中，透明显示区域与正常显示区域之间还包括过渡区，透明显示区域的像素电路一般放置在过渡区。过渡区的存在，使得透明显示区域的大小受限，影响摄像头的成像质量。并且若过渡区和透明显示区域的面积之和过大，将不利于全面屏的实现。此外，由于透明显示区域与正常显示区域单独驱动，导致透明显示区域与正常显示区域的显示画面存在差异，影响了显示效果。

[0042]针对上述问题，本发明实施例提供了一种显示面板。图1是本发明实施例提供的一种显示面板的结构示意图，图2是本发明实施例提供的一种显示装置的结构示意图。结合图1和图2，该显示面板100具有显示区AA和非显示区NAA，显示区AA包括第一显示区A1和第二显示区A2，第二显示区A2的透光率大于第一显示区A1的透光率，显示面板100包括：驱动信号线、发光器件、多个第一像素电路10和多个第二像素电路20；发光器件包括位于第一显示区A1的第一发光器件D1和位于第二显示区A2的第二发光器件D2；第一像素电路10位于第一显示区A1，第一像素电路10连接驱动信号线，第一像素电路10用于驱动第一显示区A1中的第一发光器件D1发光；第二像素电路20位于第二显示区A2，第二像素电路20连接驱动信号线，每个第二像素电路20用于驱动第二显示区A2中的至少两个第二发光器件D2发光(图1示出了第二像素电路20连接两个第二发光器件D2的情况)。

[0043]其中，第一显示区A1为正常显示区，第二显示区A2为透明显示区，显示装置400中，在显示面板100的非显示侧对应于第二显示区A2的区域，可以设置感光器件，例如屏下摄像头。在显示模式下，第一显示区A1和第二显示区A2均进行正常的...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a first display area and a second display area, the light transmittance of the second display area is larger than that of the first display area, and the display panel comprises a driving signal line; the light-emitting devices comprise a first light-emitting device located in the first display area and a second light-emitting device located in the second display area; the first pixel circuit is located in the first display area, and the first pixel circuit is connected with the driving signal line and used for driving the first light-emitting device to emit light; the second pixel circuits are located in the second display area, the second pixel circuits are connected with the driving signal lines, and each second pixel circuit is used for driving at least two second light-emitting devices to emit light. According to the technical scheme, the area of the transparent display area can be increased, and the full-screen design without a transition area is achieved.

Description

Technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the continuous development of display technology, the screen-to-body ratio of smartphone displays is getting larger and larger, and full screens will become the mainstream of future display screens. The existing full-screen design usually uses an Under Display Camera (UDC), that is, the camera is placed under the display screen. [0003] In the display screen, the pixel circuit of the camera area under the screen is usually arranged in the transition area. The existence of the transition area limits the size of the camera area under the screen, which affects the imaging quality of the camera. In addition, there is a difference between the display screen of the camera area under the screen and the normal display area, which affects the display effect. Contents of the invention ...
