Detailed Description

Features and exemplary embodiments of various aspects of the present application will be described in detail below, and in order to make objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

It will be understood that when a layer, region or layer is referred to as being "on" or "over" another layer, region or layer in describing the structure of the component, it can be directly on the other layer, region or layer or intervening layers or regions may also be present. Also, if the component is turned over, one layer or region may be "under" or "beneath" another layer or region.

In electronic devices such as mobile phones and tablet computers with high screen ratio, a front-facing camera is usually disposed below a display screen, and the display screen is divided into a main screen area and an auxiliary screen area. In order to ensure the image pickup effect of the front-facing camera, the pixel density of the secondary screen area in the electronic equipment is generally lower than that of the primary screen area.

Because the main screen area and the auxiliary screen area have the difference of pixel density, the difference can cause the sudden change of pixel distance at the junction of the main screen area and the auxiliary screen area, thereby enabling human eyes to observe an obvious boundary and influencing the experience.

In order to solve the above problem, embodiments of the display panel and the display device are provided, and the following description will be made with reference to the accompanying drawings.

The Display panel provided in the embodiment of the present application may be a Liquid Crystal Display panel (LCD for short), an Organic Light-Emitting Diode (OLED) Display panel, a Quantum Dot Light-Emitting Diode (QLED for short), or a Micro flat Display panel (Micro-OLED or Micro-LED). The description will be given taking the display panel as an OLED display panel as an example.

For better understanding of the present application, the display panel and the display device according to the embodiment of the present application are described in detail below with reference to fig. 1 to 5.

Referring to fig. 1, an embodiment of the present application provides a display panel having a first display area AA1 and a second display area AA2 surrounding the first display area AA 1. In order to improve the screen ratio, a scheme of arranging a camera below the display screen may be adopted, that is, the light transmittance of the first display area AA1 is greater than that of the second display area AA2, and it can also be understood that the first display area AA1 is a transparent display area, and the transparent display area may be used for arranging optical elements such as a camera, and thus may be regarded as a sub-screen area of the display panel, and the second display area AA2 may be regarded as a main screen area of the display panel. In addition, the pixel distribution density of the second display area AA2 is greater than that of the first display area AA 1.

The embodiment of fig. 1 is illustrated by taking the first display area AA1 as a square area and being located at the upper part of the display panel, but is not limited thereto. For example, in other embodiments, the first display area AA1 may take other shapes, and the position of the first display area AA1 may be adjusted. For example, in other embodiments, the display panel may be adjusted to have other shapes.

Referring to fig. 1 and fig. 2, the display panel according to the embodiment of the present disclosure includes a first pixel unit 11 and a second pixel unit 12, wherein a plurality of first pixel units 11 are arranged in an array in a first display area AA1 and are spaced apart from each other, a plurality of second pixel units 12 are arranged in an array in a second display area AA2 and are spaced apart from each other, a distance between two adjacent first pixel units 11 increases from a boundary h between the first display area AA1 and the second display area AA2 to a direction away from the boundary h, and a distance between two adjacent first pixel units 11 is less than or equal to twice a distance between two adjacent second pixel units 12. When the distance between two adjacent first pixel units 11 increases from the boundary h between the first display area AA1 and the second display area AA2 to a direction away from the boundary h, the pixel distance in the first display area AA1 and the second display area AA2 tends to increase, so that the main and sub-screen areas are prevented from having obvious boundaries due to the abrupt change of the distance; and the pitch between two adjacent first pixel units 11 is less than or equal to twice the pitch between two adjacent second pixel units 12, it is possible to further prevent the pixels in the first display area AA1 and the second display area AA2 from being not in the same array, which may cause the phenomenon of image misalignment when displaying.
