Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In order to solve the problem of insufficient brightness of the under-screen camera in the prior art, embodiments of the present application provide a display panel and a display device, which will be described below with reference to the accompanying drawings.
For example, referring to fig. 1, fig. 1 is a schematic side view of a display device according to an embodiment of the present application. The embodiment of the application provides a display device 1, the display device 1 may include a display panel 10 and a cover plate 20, where the cover plate 20 is disposed on a display surface of the display panel 10. The cover 20 is typically a transparent glass sheet, and the cover 20 may also be referred to as a screen. The display panel 10 is a structure composed of a multi-layer structure, for example, the display panel 10 may include a light emitting layer and a driving circuit layer for driving the light emitting layer to emit light, and of course, when the light emitting layer or the driving circuit layer is provided, there may be a multi-layer protection layer or a spacer layer structure. The display device 1 may be a mobile electronic device such as a mobile phone, a tablet computer, or a notebook computer, or the display device 1 may be a device having a display function such as a computer device, a television, or a vehicle-mounted computer.
With the development and progress of technology, people are no longer satisfied with the scheme of digging holes in the cover plate 20 to arrange the camera, but the eyes are transferred to the full screen technology. For example, the under-screen camera technology is just a "helper" to achieve a full-screen effect. The under-screen camera technique is understood to mean that the camera is placed under the cover plate 20 or screen, unlike the hole-digging screen technique, the camera area also retains the full screen display function. However, in the prior art, there is a problem of insufficient brightness of the under-screen camera.
In order to solve the above-described problems, the embodiment of the present application improves the display panel 10.
For example, please refer to fig. 1 in combination with fig. 2, fig. 2 is a schematic diagram of a first structure of a display panel in the display device shown in fig. 1. The display panel 10 may include a display region 11 and a non-display region, which is disposed around the display region 11, and which may also be referred to as a bezel region, and which is generally used to arrange wires. With the popularity of full screen technology, the width of the non-display area or border area is becoming smaller and smaller. In some embodiments, the display panel 10 may also include only the display area 11, and the wires are all arranged to the rear surface of the display area 11.
The display area 11 may include a camera area 110 and a non-camera area 112, which is a division of the display area 11 according to an area where the camera is located. It will be appreciated that the display area 11 is composed of a camera area 110 and a non-camera area 112, the non-camera area 112 is used for displaying a picture, the camera area 110 is used for displaying a picture and entering light when the camera shoots, and the area of the camera is smaller, so that the area of the camera area 110 is smaller than that of the non-camera area 112.
For example, please refer to fig. 3 in combination with fig. 1 and fig. 2, fig. 3 is a schematic diagram of a second structure of the display panel in the display device shown in fig. 1. The display panel 10 may include a first substrate 12, a first pixel group 13, a second substrate 16, and a first driving circuit 17. The first pixel group 13 is disposed on the first substrate 12, and the first pixel group 13 is located in the camera area 110. The second substrate 16 is disposed on a side of the first substrate 12 facing away from the first pixel group 13, and an area of the second substrate 16 is smaller than an area of the first substrate 12. The first driving circuit 17 is disposed on a side of the second substrate 16 facing the first substrate 12, and the first driving circuit 17 is located in the non-camera region 112. The first driving circuit 17 is electrically connected to the first pixel group 13 to drive the display of the first pixel group 13. By disposing the first pixel group 13 of the camera area 110 and the first driving circuit 17 of the first pixel group 13 on two substrates, and disposing the first driving circuit 17 on the non-camera area 112, it is possible to help reduce the area for display in the first pixel group 13, and further, the area of the first pixel group 13 that can transmit light is larger, and the light transmission area is positively correlated with the brightness, thereby improving the brightness of the under-screen camera.
The display panel 10 may further include a second pixel group 18 and a second driving circuit 19, where the second pixel group 18 is disposed on a side of the first substrate 12 facing away from the second substrate 16, and the second pixel group 18 is located in the non-camera area 112, and the second pixel group 18 is used for displaying the whole display panel 10 except the camera area 110. It will be appreciated that the second pixel group 18 is laid on the non-camera area 112, the first pixel group 13 is laid on the camera area 110, and the area of the non-camera area 112 is larger than the area of the camera area 110, so the area of the second pixel group 18 is larger than the area of the first pixel group 13. The second pixel group 18 is used for displaying the non-camera area 112, and the second pixel group 18 may include a layer structure of a light emitting layer, and the light emitting layer may include a plurality of light emitting units arranged in an array. The second driving circuit 19 is disposed between the second pixel group 18 and the first substrate 12, and the second driving circuit 19 is located in the non-camera area 112. The second driving circuit 19 is electrically connected to the second pixel group 18 to drive the display of the non-camera area 112. The second driving circuit 19 may be a stacked structure, for example, the second driving circuit 19 may include a thin film transistor (Thin Film Transistor, TFT), which is a stacked structure composed of a source, a drain, and a gate.
The first substrate 12 and the second substrate 16 may be understood as a base layer, and the driving circuit or the light emitting layer is fabricated by using the first substrate 12 or the second substrate 16 as a base. For example, the first substrate 12 and the second substrate 16 may each be made of Polyimide (PI) material. The area of the first substrate 12 is larger than the area of the second substrate 16, as determined by the area of the devices fabricated thereon. It should be noted that, the area of the first substrate 12 corresponding to the non-camera area 112 is further provided with the second pixel group 18 and the second driving circuit 19, that is, the first substrate 12 is not only used for carrying the first pixel group 13 of the camera area 110, but also the first substrate 12 is used for carrying the second pixel group 18 and the second driving circuit 19 of the non-camera area 112. The second substrate 16 is mainly used for carrying the first driving circuit 17, the first driving circuit 17 is used for driving the first pixel group 13 to emit light or display, and the first pixel group 13 is disposed in the camera area 110, and the area of the camera area 110 is generally smaller than that of the non-camera area 112, so that the area of the second substrate 16 is smaller than that of the first substrate 12. The first driving circuit 17 is removed from the camera area 110 and disposed on the second substrate 16, and then attached to the non-camera area 112, and the first substrate 12 and the structure thereon are spliced with the second substrate 16 and the structure thereon to form a complete structure of the display panel 10. The first driving circuit 17 thus arranged can help to increase the area for camera light entering in the first pixel group 13 of the camera area 110, and the brightness of the camera is positively correlated with the area of the light entering area, so that the brightness of the under-screen camera can be increased.
For example, please refer to fig. 1-3 in combination with fig. 4, fig. 4 is a schematic diagram of a portion of the first pixel group in the display panel shown in fig. 3. The first pixel group 13 may include a plurality of pixel units 130, and each pixel unit 130 may include a pixel region 131 and a transparent region 132 adjacent to each other, the pixel region 131 is configured to emit light, the transparent region 132 is configured to transmit light entering the camera, and an area of the transparent region 132 is larger than an area of the pixel region 131. In the prior art, the first driving circuit of the first pixel group is generally disposed in the camera area together with the first pixel group, and the areas of the pixel area and the transparent area are equal, or the area of the pixel area is larger than the area of the transparent area. This may result in an area of the pixel region not being reduced further, and thus the area of the transparent region being limited, thereby resulting in insufficient brightness of the under-screen camera. In order to reduce the area of the pixel region 131, the first driving circuit 17 is disposed in the non-camera region 112, so that the area of the pixel region 131 can be reduced, and the area of the transparent region 132 is correspondingly increased to improve the brightness of the under-screen camera. The area of the pixel region 131 is reduced, and compensation can be performed by increasing the current flowing through the pixel region 131, so that the light emission luminance of the pixel region 131 tends to be unchanged, thereby leaving the display of the pixel region 131 unaffected.
It will be appreciated that the structural composition of the first pixel group 13 is different from the structural composition of the second pixel group 18. Because the first pixel group 13 includes both the pixel area 131 for display and the transparent area 132 for camera light entry. And the second pixel group 18 is used for display only, the second pixel group 18 may include only the pixel area for display.
For example, please refer to fig. 1-4 in combination with fig. 5, fig. 5 is a schematic diagram of a first portion of a display panel in the display device shown in fig. 1. Each pixel unit 130 includes a light emitting portion 133 and a protective layer 134. The light emitting portion 133 is disposed on a side of the first substrate 12 facing away from the second substrate 16, and the light emitting portion 133 is located in the pixel region 131. The protection layer 134 is disposed between the light emitting portion 133 and the first substrate 12 and is located in the pixel region 131. It should be noted that, the area of each pixel unit 130 corresponding to the transparent area 132 may be provided with a transparent filling material, so that the thickness of the transparent area 132 and the thickness of the pixel area 131 are consistent.
The display panel 10 may further include a first conductive line 14a. The protective layer 134 is provided with a first via hole 135, the first substrate 12 is provided with a second via hole 120, the first conductive wire 14a is inserted into the first via hole 135 and the second via hole 120, and the light emitting portion 133 is connected to the first driving circuit 17 through the first conductive wire 14a. Illustratively, the first via 135 and the second via 120 are offset such that the first wire 14a has an extended space and path.
For the second substrate 16, an isolation layer 15 is further disposed thereon, that is, the display panel 10 may further include the isolation layer 15, where the isolation layer 15 is disposed on a side of the second substrate 16 facing the first substrate 12. The first driving circuit 17 may be embedded in the isolation layer 15, that is, the isolation layer 15 is laid on the second substrate 16, and the whole formed by the second substrate 16 and the isolation layer 15 may be partially disposed in the camera area 110, so that the arrangement and arrangement of the wires may be facilitated, and the length of the wires may be reduced, for example, the length of the first conductive wire 14a may be reduced. The other part of the whole formed by the second substrate 16 and the isolation layer 15 is disposed in the non-camera region 112, and the first driving circuit 17 is disposed correspondingly in the non-camera region 112. Of course, the second substrate 16 and the isolation layer 15 may be disposed in the non-camera region 112, and the first pixel group 13 and the first driving circuit 17 may be connected by the first conductive line 14a, where the length of the corresponding first conductive line 14a is greater than that of the first conductive line 14a in the above case. The isolation layer 15 may be provided with a third via 150, and the first conductive line 14a further penetrates through the third via 150 and is connected to the first driving circuit 17. It can be understood that one end of the first wire 14a is connected to the light emitting part 133 and then passes through the first via hole 135, the second via hole 120, and the third via hole 150 to be connected to the first driving circuit 17. In order to save the length of the first conductive line 14a, the first driving circuit 17 may be disposed in the non-camera region 112 near the camera region 110, so that the path spanned by the first conductive line 14a is reduced, that is, the length of the first conductive line 14a is shortened, and thus the wire may be saved.
It should be noted that the first driving circuit 17 and the second substrate 16 are formed not only in a small area but also in a small thickness. Illustratively, the first driving circuit 17 and the second substrate 16 have a first thickness, and the second pixel group 18, the second driving circuit 19, and the first substrate 12 have a second thickness, which is greater than the first thickness. In manufacturing the display panel 10, the second pixel group 18, the first pixel group 13 and the second driving circuit 19 may be disposed on the first substrate 12, respectively, to obtain a main board structure. Then, the first driving circuit 17 is fabricated on the second substrate 16 alone, resulting in a sub-board structure. Finally, the sub-board structure is attached to the position of the main board structure corresponding to the non-camera area 112, and the first pixel group 13 is connected with the first driving circuit 17 through the first wire 14a.
For example, please refer to fig. 1-5 in combination with fig. 6, fig. 6 is a schematic diagram of a second portion of the display panel in the display device shown in fig. 1. The signal source of the first driving circuit 17 may be connected to the signal source through an external wire, and the signal source may provide a signal to both the second driving circuit 19 and the first driving circuit 17. Of course, the signal source of the first driving circuit 17 may also be from the second driving circuit 19, that is, the first driving circuit 17 needs to be connected to not only the first pixel group 13, but also the second driving circuit 19 to introduce the signal of the second driving circuit 19 to the first driving circuit 17. The display panel 10 may further include a second conductive line 14b, the second conductive line 14b connecting the second driving circuit 19 and the first driving circuit 17, for example. The first substrate 12 is further provided with a fourth via 124, and the second conductive line 14b is disposed through the fourth via 124. That is, the first driving circuit 17 and the second driving circuit 19 are connected by providing wires through holes. In order to facilitate the arrangement of the second wires 14b, the protective layer 134 and the isolation layer 15 may also be provided with vias for the second wires 14b to pass through, and the manner of passing the second wires 14b through the vias may refer to the manner of disposing the first wires 14a, which is not described herein again.
In an exemplary embodiment, please refer to fig. 1 to 6 in combination with fig. 7, and fig. 7 is a schematic diagram of a third structure of the display panel in the display device shown in fig. 1. A recess 122 may be provided on a side of the first substrate 12 facing the second substrate 16, the recess 122 being adapted to accommodate at least part of the first driving circuit 17. Although the thickness of the first driving circuit 17 and the second substrate 16 is smaller, when the first driving circuit is attached to the first substrate 12, there is still a portion protruding, which affects the appearance or the subsequent process. Therefore, the recess 122 may be disposed on a side of the first substrate 12 facing the second substrate 16, and the recess 122 may accommodate at least a portion of the first driving circuit 17, so as to reduce the protruding thickness of the second substrate 16 relative to the first substrate 12, improve the aesthetic appearance, and facilitate the subsequent process.
In the display panel 10 and the display device 1 provided in this embodiment of the present application, the first pixel group 13 of the camera area 110 and the first driving circuit 17 of the first pixel group 13 are disposed on two substrates, and the first driving circuit 17 is disposed in the non-camera area 112, which can help to reduce the area used for displaying in the first pixel group 13, and further make the area capable of transmitting light in the first pixel group 13 larger, and the light transmission area positively correlates with the brightness, so as to improve the brightness of the under-screen camera.
