The sub-pixels 31 are used for emitting light, so that the display panel 10 is used for displaying an image to be displayed.
For example, the sub-pixel 31 may be an organic light emitting unit or other light emitting units known to those skilled in the art, and the embodiment of the invention is not limited thereto.
For example, the light emitting color of the sub-pixel 31 may be red, green, blue, white, yellow, orange, or other colors known to those skilled in the art, and the embodiment of the invention is not limited thereto.
The sub-pixel reservation region 30 can be divided into two parts, wherein one part of the sub-pixel reservation region 30 is used for disposing the sub-pixels 31, i.e. forming the light emitting region 122 in the second display region 112, and forming the first display region 111; the sub-pixels 31 are not disposed in the other part of the sub-pixel reserved area 30, the part of the sub-pixel reserved area 30 is used as a light transmitting area 121, and the light transmitting area 121 can allow light to pass through, so that ambient light can be incident to a sensor module disposed on the backlight side of the display panel 10 through the display panel 10, and the sensor module can detect ambient environmental information.
It is also understood that all the sub-pixel reservation regions 30 in the first display region 111 are used to set the sub-pixels 31, i.e., are used to emit light, so that the first display region 111 is used only to display an image; the reserved sub-pixel area 30 in the second display area 112 can be divided into two parts, wherein one part of the reserved sub-pixel area 30 is used for arranging the sub-pixels 31, i.e. forming the light emitting area 122, and the light emitting area 122 is used for displaying the image to be displayed together with the first display area 111, so that the display panel can realize real full-screen display; the sub-pixels 31 are not arranged in the other part of the sub-pixel reserved area 30, that is, the light transmitting area 121 is formed, and the light transmitting area 121 can allow light to pass through, so that the sensor module can be integrated with the display panel 10, and the sensing detection of environmental information can be realized while the display device formed subsequently realizes full-screen display.
By setting the number of the sub-pixel reserved areas 30 in the first pixel unit 310 and the second pixel unit 320 to be N, the same process can be used to form the sub-pixel reserved areas 30 in the first display area 111 and the second display area 112 simultaneously in the actual manufacturing process of the display panel 10, thereby facilitating simplification of the process. Regarding the structural difference between the light-transmitting region 121 and the light-emitting region 122, it can be understood that the light-transmitting region 121 only lacks several functional film layers than the light-emitting region 122, and it can be understood by combining the process, that in the manufacturing process of the display panel, a part of the functional film layer is not formed at the corresponding position of the light-transmitting region 121, so that the light-transmitting region 121 has higher light transmittance relative to the light-emitting region 122, and the sensor module disposed at the corresponding position can normally operate.
For example, the value of N may be 1, 2, or 3 or other selectable positive integers, which may be set according to actual requirements of the display panel 10, and this is not limited in this embodiment of the present invention.
For example, the number of the second pixel units 320 in the second pixel unit 320, in which the light-transmitting regions 121 are disposed, and the ratio of the number of the light-transmitting regions 121 in each pixel unit 320 to the sub-pixel reserved area 30 may be set according to actual requirements of the display panel 10, which is not limited in the embodiment of the invention.

For example, when the value of N is 3, the value of M may be 1, as shown in fig. 1. Alternatively, M may also take the value of 2, as shown in fig. 2. In other embodiments, each of the second pixel units 320 including the light transmissive regions 121 may further be arranged, where the number of the light transmissive regions 121 is different, for example, when the value of N is 3, the value of M in a part of the second pixel units 320 is 1, and the value of M in a part of the second pixel units 320 is 2, which is not limited in this embodiment of the present invention.

When the display panel 10 is an organic light emitting display panel, the light emitting layer 420 is an organic light emitting layer, and the auxiliary light emitting layer 430 may be a carrier auxiliary functional layer, which may exemplarily include a hole injection layer, a hole transport layer, an electron blocking layer, an electron injection layer, an electron transport layer, a hole blocking layer, and other auxiliary light emitting functional layers known to those skilled in the art, which is not limited in the embodiment of the present invention; the driving circuit layer 410 is used for forming a pixel driving circuit, and may include a thin film transistor, a storage capacitor, and other circuit elements known to those skilled in the art, which are not limited by the embodiments of the present invention.
The light emitting layer 420 and the auxiliary light emitting layer 430 are usually made of materials with high light transmittance, the structure of the pixel driving circuit in the driving circuit layer 410 is complicated, and the driving circuit layer 410 usually includes materials with low light transmittance, even opaque materials; therefore, the light emitting layer 420 and the auxiliary light emitting layer 430 may remain in the light transmitting region 121, and the driving circuit layer 410 may be removed. Thus, while ensuring that the light-transmitting region 121 has a light transmittance satisfying the sensor module, the process of the display panel 10 is simplified, thereby reducing the difficulty in manufacturing the display panel 10.
In addition, in order to increase the light transmittance of the light-transmitting region 121, the light-emitting layer 420 and/or the auxiliary light-emitting layer 430 may be removed together. At this time, the removed film layer in the light-transmitting region 121 may be filled with a material having a relatively high transmittance, so that the display panel 10 may be relatively flat, which is favorable for ensuring the overall stability of the display panel 10 and improving the reliability of the display panel 10.
Optionally, fig. 8 is a schematic cross-sectional structure diagram of another display panel according to an embodiment of the present invention. Referring to fig. 3 and 8, each of the first and second pixel units 310 and 320 includes a driving circuit layer 410, a light emitting layer 420, and an auxiliary light emitting layer 430; the driving circuit layer 410, the light emitting layer 420 and the auxiliary light emitting layer 430 of the second pixel unit 320 do not overlap with the light transmitting region 121.
In the light-transmitting region 121, the driving circuit layer 410, the light-emitting layer 420 and the auxiliary light-emitting layer 430 are all removed to increase the light transmittance of the region.
On the basis, the transparent material layer 450 with high transmittance is used to fill the region, so that the surface of the display panel 10 is relatively flat, thereby being beneficial to improving the reliability of the display panel.
It should be noted that fig. 7 and fig. 8 only show the relative positions of the driving circuit layer 410, the light emitting layer 420, and the auxiliary light emitting layer 430 by way of example, but details of the respective film layers are not shown. In the actual structure of the display panel 10, the specific film structures of the driving circuit layer 410, the light emitting layer 420 and the auxiliary light emitting layer 430 may be set according to the actual requirements of the display panel, and the embodiment of the invention does not limit this.
In addition, it should be noted that the display panel 10 may further include a substrate 400, an encapsulation film layer 440, and other functional film layers known to those skilled in the art, which is not limited by the embodiment of the invention.
Optionally, fig. 9 is a schematic cross-sectional structure diagram of another display panel provided in an embodiment of the present invention, and illustrates a schematic cross-sectional structure diagram of the display panel when the display panel 10 is a liquid crystal display panel.

The color resist layer 540 includes a functional film layer capable of filtering light on the color film substrate. Illustratively, the color resist layer 540 may include a black matrix, a red resist block, a green resist block, a blue resist block, and other color resist structures known to those skilled in the art.
Since the pixel driving circuit in the liquid crystal display panel is simple, the light transmittance of the driving circuit layer 530 is high; the light transmittance of the color resistance layer is low, and the light can be emitted in the color corresponding to the color of the color resistance layer after passing through the color resistance layer. Therefore, the driving circuit layer 530 can be remained in the transparent region 121, and the color-resist layer 540 needs to be removed. Thus, while ensuring that the light-transmitting region 121 has a light transmittance satisfying the sensor module, the process of the display panel 10 is simplified, thereby reducing the difficulty in manufacturing the display panel 10.
In addition, in order to increase the light transmittance of the light-transmitting region 121, the driving circuit layer 530 may be removed together. At this time, the removed film layer in the light-transmitting region 121 may be filled with a material having a relatively high transmittance, so that the display panel 10 may be relatively flat, which is favorable for ensuring the overall stability of the display panel 10 and improving the reliability of the display panel 10.
