In the embodiments of the present disclosure, as shown inFIG.1, the first display area100and the second display area200are combined to form at least a part of the display area of the display panel, and optionally, form the entire display area of the display panel.

Optionally, the display panel is an OLED display panel, the light-emitting device unit210is an OLED light-emitting unit in an OLED pixel unit, and the light-emitting driving unit310is a driving unit for driving the OLED light-emitting unit to emit light.

In the embodiment of the present disclosure, optionally, the display panel includes a transparent base substrate, the pixel unit110, the light-emitting device unit210, and the light-emitting driving unit310are all formed on the transparent base substrate, and the light-emitting device unit210is made of a light-transmitting material and is formed to have a light-transmitting structure, so that the second display area200is formed as a transparent display area. Optionally, the light-emitting device unit210is not limited to only being made of light-transmitting materials, and may also utilize the light transmittance function of the gap between the spaced light-emitting device unit210to form the light transmitting effect of the second display area200.

In the embodiment of the present disclosure, optionally, the first display area100surrounds the second display area200, or the second display area200is provided on one of the edges of the first display area100. Optionally, the pixel unit110provided in the first display area100may be made of a light-transmitting material, or may not be made of a light-transmitting material, which is not limited herein.

In the display panel adopting this implementation structure, a camera can be provided on the side of the second display area200far away from the display panel. By using the light-transmitting function of the second display area200, light incident on the display panel can be transmitted to the camera for image capturing. In addition, since the second display area200is further provided with the light-emitting device unit210, the light-emitting driving unit310of the pixel auxiliary area300can drive the light-emitting device unit210to emit light, so the second display area200can also be used to realize image display.

Since in this embodiment, the light-emitting driving unit310for driving the light-emitting device unit210of the second display area200to emit light is provided external to the first display area100and the second display area200, so that the area for providing the corresponding camera includes only the light-emitting device unit210, and the distribution density of the connecting wires that connect the light-emitting device unit210and the light-emitting driving unit310in the display area is reduced. Therefore, with the same area, the display panel according to the embodiment of the present invention can increase a number of the light-emitting device units210and can prevent the light transmittance from being affected by the setting of the connecting wires, so that the requirements for light transmission and display resolution can be simultaneously satisfied.

The embodiments of the present disclosure further provide a display device, which includes the display panel as described in any one of the above.

With reference toFIGS.1to11and referring to the above detailed description, those skilled in the art should be able to understand the specific structure of the display device adopting the display panel of any one of the above embodiments, which will not be described in detail here.

Another aspect of the embodiments of the present disclosure further provides a manufacturing method of the display panel as described above, the method includes:providing a transparent base substrate;preparing a plurality of pixel units in a first area of the base substrate to form the first display area; preparing a plurality of transparent light-transmitting device units in a second area of the base substrate to form the second display area; and preparing a plurality of light-emitting driving units in a third area of the base substrate to form the third display area, and the light-emitting driving units are used to drive the connected light-emitting device units to emit light. In the embodiments of the present disclosure, when a plurality of pixel units are prepared in the first area, the light-emitting device unit in the second area and the light-emitting driving unit in the third area can be prepared at the same time, as well as the connection between the units.

The specific structures of the pixel unit, the light-emitting device unit, and the light-emitting driving unit, as well as the mutual structural relationship and the forming process relationship, can refer toFIG.1toFIG.11and the above detailed description, which will not be described here.

In the display panel, display device and manufacturing method thereof, by providing the light-emitting driving unit for driving the light-emitting device unit of the second display area to emit light in the area outside the first display area and the second display area, the area set corresponding the camera area only includes the light-emitting device unit, and the distribution density of the connecting wire for connecting the light-emitting device unit and the light-emitting driving unit in the display area is reduced, thereby solving the problem that in a display panel using an under-screen-camera in the prior art, it is difficult for the transparent display area corresponding to the camera to simultaneously satisfy the requirements for light transmission and display resolution.

Unless otherwise defined, the technical or scientific terms used in the present disclosure shall have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure belongs. The terms “first”, “second”, and the like used in this disclosure do not indicate any order, quantity, or priority, but are only used to distinguish different components. The terms “include”, “have” or any variations thereof are intended to mean that an element or article followed by such a term encompasses a list of elements or articles preceded by such a term, or equivalents thereof, without precluding other elements or articles. Expressions such as “connection” or “connected” are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Such words as “on”, “under”, “left” and “right” are merely used to represent relative position relationship, and when an absolute position of the object is changed, the relative position relationship will be changed too.

It will be understood that when an element, such as a layer, film, area or substrate, is referred to as being “on” or “under” another element, it can be directly on or directly under the other element, or intervening elements may also be present.

The specific features, structures, materials or characteristics in the description of forgoing implementations may be combined in any one or more embodiments or examples in proper manners.

The above descriptions merely describe specific implementations of the present disclosure, and the scope of the present disclosure is not limited thereto. Any modifications or substitutions easily occurring to a person of ordinary skill in the art without departing from the principle of the present disclosure shall fall within the scope of the present disclosure. Therefore, the scope of the present disclosure is defined by the scope of the claims.
