On a display device such as a mobile phone and a tablet computer, it is necessary to integrate a graphic capture component such as a front camera on the side where a display panel is provided. In some embodiments, a transparent display area may be disposed on the electronic device, and the image capturing component may be disposed behind the transparent display area. However, in the display device in the prior art, the pixels above the image acquisition part are continuously displayed to cause the image acquisition part under the screen to be unable to be normally used, which affects the performance of the display device, for this, a processing mode in the prior art is that the terminal system performs shading processing on the image acquisition part, namely, the image acquisition part corresponds to an area black screen display, which can reduce the influence of pixel opening on the light entering the display area where the image acquisition part is located to a certain extent, so as to realize the use requirement of the image acquisition part on the light.
However, the problem that the main interface or the corresponding area of the self-contained menu page of the system can only be processed by the mode is that the display is performed in a black screen mode, and the APP interface of the third party cannot meet the requirement that the image acquisition component works, namely, the display is performed in the black screen mode, so that the functional requirement of the image acquisition component is influenced.
In order to solve the above problems, embodiments of a display panel and a display device according to the present invention are described below with reference to fig. 1 to 6.
Embodiments of the present invention provide a display panel, which may be an Organic Light Emitting Diode (OLED) display panel.
Referring to fig. 1 to 6, an embodiment of the invention provides a display panel 100 having a first display area AA1 and a second display area AA2, wherein a light transmittance of the first display area AA1 is greater than or equal to 15%. In order to ensure that the light transmittance of the first display area AA1 is greater than 15%, even greater than 40%, or even higher, the light transmittance of each functional film layer of the display panel 100 in this embodiment is greater than 80%, and even at least some of the functional film layers are greater than 90%.

Optionally, the second display area AA2 includes a main display area AA2a and an irregular display area AA2 b. Alternatively, the area of the second display area AA2 is larger than that of the first display area AA1, and at the same time, the second display area AA2 is disposed to surround at least a portion of the first display area AA 1. The main display area AA2a is disposed adjacent to the shaped display area AA2 b. In some alternative examples, the shaped display area AA2b may be located at an edge of the display panel 100. As an alternative embodiment, the first display area AA1 and the irregular display area AA2b are spaced apart from each other.

As an alternative embodiment, the display panel 100 includes a first pixel group 10, a second pixel group 20, and an integrated circuit 30. The first pixel group 10 is disposed in the first display area AA1 and includes a plurality of first pixels 110, the second pixel group 20 is disposed in the second display area AA2, and the second pixel group 20 includes second pixels 210 distributed in the main display area AA2a and third pixels 220 distributed in the irregular display area AA2 b. The integrated circuit 30 is used for controlling the first pixel 110 of the first display area AA1 and the third pixel 220 of the irregular display area AA2 b.
As shown in fig. 2, in order to more clearly understand the main display area AA2a and the irregular display area AA2b, the second display area AA2 is divided into two partial areas by a dotted line in fig. 2, and the dotted line is only a virtual line for better understanding assistance and may not exist in an actual product.
The dividing of the special-shaped display area and the main display area is not limited to the dividing manner of the embodiment shown in fig. 2 of the present invention, and the dividing may be specifically performed according to the size and shape of the position where the edge of the display panel 100 has an arc transition. For example, in some alternative dividing manners, the area where each pixel that is close to the special-shaped edge of the display panel 100 and can affect smooth display of the special-shaped edge is located may be collectively referred to as a special-shaped display area AA2b, and the pixels located in the special-shaped display area AA2b are referred to as third pixels 220.
Optionally, in the display panel 100 provided in the embodiment of the invention, the integrated circuit 30 controls the first pixel 110 to start to participate in the display in the first functional mode of the first display area AA1, and the integrated circuit 30 controls the first pixel 110 to turn off in the second functional mode of the first display area AA1, so that the light passes through the first display area AA 1. In addition, the integrated circuit 30 in the first functional mode and/or the second functional mode of the first display area AA1 controls the third pixels 220 distributed in the irregular display area AA2b, so that the arc-shaped edge of the irregular display area AA2b has smooth transition.
In the display panel 100 provided in the embodiment of the invention, since the integrated circuit 30 controls the first pixel 110 to start to participate in the display in the first functional mode of the first display area AA1, the screen occupation ratio of the display panel 100 can be improved. The integrated circuit 30 in the first display area AA1 controls the first pixel 110 to turn off in the second functional mode, so that light can pass through the first display area AA1, the photosensitive requirement of the image capturing component 200 can be met, the image capturing component is not limited by the APP interface of the third party, and the practical performance of components such as the image capturing component 200 in the display device to which the image capturing component is applied and the like which need light cannot be affected.
Moreover, the integrated circuit 30 can also control the third pixels 220 distributed in the irregular display area AA2b in the first functional mode and/or the second functional mode, so as to enable the arc-shaped smooth transition of the irregular edge of the irregular display area AA2b, and further reduce or avoid the phenomenon of saw-toothed edge display of the display panel 100, that is, the display panel 100 provided by the embodiment of the invention can simultaneously control the arc-shaped smooth transition display of the edge of the irregular display area AA2b and the on and off of the first pixel 110 corresponding to the first display area AA1 through the integrated circuit 30, so as to ensure the display effect, and the same integrated circuit 30 is used to control two different areas, so that the structure of the display panel 100 can be simplified, and the integrated circuit 30 has the advantages of easy molding, cost saving and the like.
In some alternative embodiments, integrated circuit 30 is at T1The first pixel 110 is controlled to be turned on in the time period, and the gray scale of the third pixel 220 in the special-shaped display area AA2b is controlled and adjusted at the same time, so that the arc shape of the special-shaped edge of the special-shaped display area AA2b is smoothly transited. At the same time, the integrated circuit 30 is at T2The time period controls the first pixel 110 to be turned off and at T2The time period control adjusts the gray scale of the third pixel 220 of the shaped display area AA2b to make the arc-shaped smooth transition of the shaped edge of the shaped display area AA2 b.
That is, the embodiment of the invention provides the display panel 100, which can control the on and off of the corresponding first pixels 110 in the first display area AA1 according to different timings through the same integrated circuit 30, and can simultaneously control and adjust the gray scale of the corresponding third pixels 220 through the integrated circuit 30 in the corresponding timings, so as to realize the arc-shaped smooth transition of the irregular edge of the irregular display area AA2 b. The on and off of each first pixel 110 corresponding to the first display area 10 can be controlled according to the requirement, so as to meet the functional requirement of the light of the image acquisition component 200. In addition, the integrated circuit 30 can be shared with the control of the third pixel 220 in the special-shaped display area AA2b, so that the structure of the display panel 100 is further simplified, and the cost is saved.
An alternative embodiment, for example, during a time period when the display panel 100 needs to display an image and the image capturing part 200 does not work, i.e., an alternative form of T1In the time period, the integrated circuit 30 may control all the first pixels 110 to be turned on in the time period, and simultaneously control and adjust the gray scale of the corresponding third pixels 220 through the integrated circuit 30, so as to realize the arc-shaped smooth transition of the special-shaped edge of the special-shaped display area AA2 b. While during the operation period of the image capturing element 200, an alternative form of T2During the time period, the integrated circuit 30 is at T2The first pixel 110 is controlled to be turned off in a time period, so that light can enter through the first display area AA1, the requirement of the image acquisition component 200 on the light is met, and the working performance of the image acquisition component is ensured. At this time, when the display panel 100 displays an image, the display panel displays an image at T2The gray scale of the corresponding third pixel 220 can be controlled and adjusted in the time period, so that the arc-shaped smooth transition of the special-shaped edge of the special-shaped display area AA2b is realized.
It should be noted that, the gray scale mentioned in the embodiments of the present invention may refer to dividing the brightness variation between the brightest and darkest into several parts, so as to facilitate the control of the screen brightness corresponding to the signal input. And the third pixel 220 gray scale of the special-shaped display area AA2b is controlled and adjusted to change the brightness of the second pixel 210 relative to the main display area AA2a, so that the edge of the display panel 100 corresponding to the special-shaped display area AA2b is blurred, and further the arc-shaped smooth transition of the special-shaped edge of the special-shaped display area AA2b is realized.
As an alternative implementation, the above embodiments refer to controlling, by the integrated circuit 30, the third pixels 220 distributed in the shaped display area AA2b to make the arc-shaped smooth transition of the shaped edge of the shaped display area AA2 b. The gray scale of the third pixel 220 in the irregular display area AA2b is not limited to be controlled and adjusted, but the arc-shaped edge of the irregular display area AA2b can be smoothly transited by controlling the turn-off of the third pixel 220 at a predetermined position in the irregular display area AA2 b.
For example, the third pixel 220 close to the arc edge of the shaped display area AA2b and approximately on an arc may be turned on, and the rest of the positions may affect the edge display, so that the third pixel 220 with the edge possibly generating jaggies is in the off state, and the arc-shaped smooth transition of the shaped edge of the shaped display area AA2b may also be satisfied.
Alternatively, in the display device 100 mentioned in the above embodiments, the integrated circuit 30 may include only one circuit module to control the shaped display area AA2b and the first display area AA1, which is an alternative embodiment, in some other examples. As shown in fig. 3, the integrated circuit 30 may also include a first circuit module 31 and a second circuit module 32, the first circuit module 31 is used for controlling the third pixels 220 of the irregular display area AA2b, and the second circuit module 32 is used for controlling the first pixels 110 of the first display area AA 1. By defining that the integrated circuit 30 includes the first circuit module 31 and the second circuit module 32 and correspondingly controls the third pixel 220 and the first pixel 110, the requirement of providing the same integrated circuit 30 to simultaneously control the first pixel 110 of the first display area AA1 and the third pixel 220 of the irregular-shaped display area AA2b can be satisfied.
Optionally, in the first functional mode, the integrated circuit 30 may control the first pixel 110 in the first display area AA1 to be turned on for display through the second circuit module 32, and control the third pixel 220 in the irregular display area AA2b to be turned off or turned on at a predetermined position through the first circuit module 31, so that the arc shape of the irregular edge of the irregular display area AA2b is smoothly transited. Optionally, in the second functional mode, the integrated circuit 30 may control, through the second circuit module 32 thereof, the first pixel 110 of the first display area AA1 to turn off, so that the light passes through the first display area AA1, and in the second functional mode, the integrated circuit 30 may also control, through the first circuit module 31 thereof, the gray scale of the third pixel 220 of the special-shaped display area AA2b or the turn-off of the third pixel 220 at the predetermined position to enable the arc-shaped smooth transition of the special-shaped edge of the special-shaped display area AA2 b.
As an alternative implementation, in the display device 100 provided in the above embodiments, the circuit topology of the first circuit module 31 may be the same as that of the second circuit module 32. Through the arrangement, the control program for the third pixel 220 in the special-shaped display area AA2b can be used for controlling the first pixel 110 in the first display area AA1, which is beneficial to the formation of the integrated circuit 30, simplifies the structure and reduces the cost.
It should be noted that the circuit topology mentioned above is also called a circuit layout, i.e. a circuit structure, which is a set formed by only branches and nodes, and abstracts the circuit layout again, and it discusses the connection relationship of the circuit and its properties, i.e. the connection relationship of the branches and the nodes.
In some optional embodiments, in the display panel 100 provided in the foregoing embodiments, the integrated circuit 30 may further include a third circuit module 33, configured to control the second pixels 210 of the main display area AA2a, that is, the first circuit module 31, the second circuit module 32, and the third circuit module 33 may be synchronously integrated on the integrated circuit 30, so as to control the pixels corresponding to each display area on the display panel 100 according to a predetermined requirement. That is, the first circuit block 31, the second circuit block 32, and the third circuit block 33 may be integrated on the same chip.
Of course, the integration of the circuit blocks for controlling the main display area AA2a on the integrated circuit 30 is only an alternative embodiment. As shown in fig. 4, in some other examples, the display panel 100 may further include a main driving circuit 40, the main driving circuit 40 is used for controlling the second pixels 210 of the main display area AA2a, and the integrated circuit 30 and the main driving circuit 40 may be respectively integrated on two different chips. With the above arrangement, the control of the second pixels 210 in the main display area AA2a can be satisfied, and the display requirement of the display panel 100 can be ensured. In addition, the main driving circuit 40 may use an existing IC chip for controlling the normal display sub-pixels, and thus the design and manufacturing cost of the entire display panel 100 can be reduced.
As an alternative implementation manner, in the display panel 100 provided in the above embodiments, the first pixel groups 10 are distributed in the first display area AA1 with a first density, and the second pixel groups 20 are distributed in the second display area AA2 with a second density, where the second density is greater than the first density. Through the above arrangement, the light transmittance of the display panel 100 can be effectively improved. Thereby better satisfying the light requirement of the image acquisition component 200.
Thus, the display panel 100 according to the embodiment of the invention includes the first pixel group 10, the second pixel group 20 and the integrated circuit 30, and the integrated circuit 30 is used for controlling the first pixel 110 in the first display area AA1 and the third pixel 220 in the irregular display area AA2 b. Because the integrated circuit 30 controls the first pixel 110 to be turned on to participate in the display in the first functional mode of the first display area AA1, and the integrated circuit 30 controls the first pixel 110 to be turned off in the second functional mode, so that the light passes through the first display area AA1, the requirement of the display panel 100 for increasing the screen area can be met, and the requirement of the image acquisition component 200 for sensing light can be met.
In addition, the integrated circuit 30 can also control the third pixels 220 distributed in the irregular display area AA2b in the first functional mode and/or the second functional mode, so as to enable the arc-shaped smooth transition of the irregular edge of the irregular display area AA2b, and further reduce or avoid the phenomenon that the edge of the display panel 100 displays jaggies, that is, the integrated circuit 30 can simultaneously control the arc-shaped smooth transition of the edge of the irregular display area AA2b and the turning on and off of the first pixels 110 in the first display area AA1, thereby simplifying the structure of the display panel 100 and saving the cost.
Referring to fig. 1 to fig. 6, optionally, a display device according to an embodiment of the present invention may further include the display panel 100 according to the foregoing embodiments. The display device can be an electronic device such as a mobile phone, a platform computer and a tablet computer.
As an alternative embodiment, the display device may further include an image pickup part 200, and a controller, the image pickup part 200 being disposed at one side of the display panel 100 and facing the first display area AA 1. Alternatively, the top surface side S1 of the display panel 100 is used for display, and the image pickup device 200 is disposed on the bottom surface side S2 of the display panel 100. The projection of the first display area 10 covers at least a part of the image pickup element 200 in the thickness direction of the display panel 100.
The controller is configured to control the first display area AA1 to switch to the second functional mode when receiving an instruction to start the image capturing component 200, so that each first pixel 110 in the first display area AA1 is turned off, and light passes through the first display area AA1, thereby meeting the requirement of the image capturing component for light. The controller is further configured to control the first display area AA1 to switch to the first functional mode when receiving an instruction to turn off the image capturing part 200, so that the first display area AA1 can be the same as a normal display image, and the screen occupation ratio of the display interface is increased.
