Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and 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 understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, the first drive circuit may be referred to as the second drive circuit, and similarly, the second drive circuit may be referred to as the first drive circuit, without departing from the scope of the present application. The first and second drive circuits are both drive circuits, but they are not the same drive circuit.
FIG. 1 is a diagram of an application environment of a display screen in one embodiment. The display screen 100 in the present application may be applied to a terminal device, which may be, but is not limited to, various smart phones, notebook computers, tablet computers, and portable wearable devices; the camera module 200 in the terminal device is located below the display screen 100.
In one embodiment, as shown in fig. 2, a display panel is provided, which includes a light emitting layer 10 and a driving circuit layer 20; wherein the light emitting layer comprises at least two display cells 101. At least two driving units 201 corresponding to the at least two display units 101 one to one are arranged on the driving circuit layer 20, and each driving unit 201 comprises a first driving circuit 2011 and a second driving circuit 2012; a lighting window is disposed at a position on the driving circuit layer 20 opposite to the display unit 101, so that at least two cameras in the camera module under the screen collect information to be shot through the lighting window 202. The first driving circuit 2011 and the second driving circuit 2012 on each driving unit 201 are respectively located at two sides of the light-emitting window 202, and the arrangement direction of at least two driving units 201 is consistent with the arrangement direction of at least two display units 101.
The light-emitting layer 10 may be composed of a plurality of light-emitting pixels, and is used for displaying pixel information of the terminal device. At least two display units 101 are included in the light emitting layer 10, and each display unit 101 includes a plurality of light emitting pixels therein. Under the condition that the display screen of the terminal equipment comprises at least two cameras, the cameras can be in one-to-one correspondence with the display units 101, and each camera is respectively positioned below the corresponding display unit 101. The display unit 101 can display pixel information under the driving of a driving circuit; the camera can also be in a light-transmitting state under the control of the driving circuit, so that the camera can acquire information to be shot through the display unit 101.
The display unit 101 may have a circular shape or other shapes such as a square shape, and the area of the display unit 101 may be larger than or equal to the area of the camera of the terminal device. The shape and size of the different display units 101 may be the same or different.
The driving circuit layer 20 is used to supply driving current to the light emitting pixels in the light emitting layer 10. The driving circuit layer 20 may be formed by stacking various film layers such as an active layer, an insulating layer, and a metal layer, and the active layer and the metal layer have low transmittance to visible light, which results in poor light transmittance of the driving circuit layer 20. In order to enable at least two cameras in the camera module under the screen to acquire information to be shot through the display screen, a lighting window 202 may be opened in a position on the driving circuit layer 20 corresponding to the display unit 101, and a driving unit 201 corresponding to the display unit 101 is externally arranged outside the lighting window 202.
Alternatively, the lighting window 202 may be a through hole, or a blind hole with a transparent bottom. When the lighting window 202 is a through hole, the driving circuit layer 20 does not include various film layers such as an active layer, an insulating layer, and a metal layer at a position corresponding to the display unit 101, so that the transmittance of the lighting window 202 for visible light is greatly improved. Under the condition that the bottom of the lighting window 202 is a blind hole in a transparent state, the driving circuit layer 20 may include a substrate or an insulating layer made of a transparent material at a position corresponding to the display unit 101, so that the driving circuit layer 20 has a rich routing space at the position corresponding to the display unit 101, and the wiring difficulty is simplified. The lighting window 202 may be a window, so that at least two cameras of the camera module collect information to be photographed through the lighting window 202; the lighting window 202 may also be a plurality of windows, so that each camera respectively collects information to be photographed through the corresponding lighting window 202, and the number of the lighting windows 202 is not limited herein.
The display units 101 are in one-to-one correspondence with the driving units 201, and each driving unit 201 is used for driving the corresponding display unit 101 to emit light. In the case of externally configuring the driving unit 201 corresponding to the display unit 101, in order to make the driving unit 201 consistent with the length of the driving line connected to each light emitting pixel in the display unit 101, the driving unit 201 may be divided into a first driving circuit 2011 and a second driving circuit 2012, and the first driving circuit 2011 and the second driving circuit 2012 are respectively disposed at two sides of the light collecting window 202. The first drive circuit 2011 and the second drive circuit 2012 drive a part of the pixels in the display unit 101, and the number of the pixels driven by the first drive circuit 2011 may be the same as or different from the number of the pixels driven by the second drive circuit 2012.
When the first driving circuit 2011 and the second driving circuit 2012 are disposed at two sides of the lighting window 202, they may be disposed above and below the lighting window 202, or disposed at the left and right of the lighting window 202, or disposed along other directions of the sampling window, which is not limited herein.
The driving units 201, which are composed of the first driving circuit 2011 and the second driving circuit 2012, may be arranged along a straight line. The arrangement direction of the driving units 201 may coincide with the arrangement direction of the display units 101. The arrangement direction of the display units 101 may be arranged along the horizontal direction of the display screen, may also be arranged along the vertical direction of the display screen, and may also be arranged along other straight lines in the display screen, which is not limited herein. Since the first driving circuit 2011 and the second driving circuit 2012 of the driving unit 201 are located at two sides of the lighting window 202 corresponding to the display unit 101, when the arrangement direction of the driving unit 201 is consistent with the arrangement direction of the display unit 101, the driving circuit of the display unit 101 does not exist between two adjacent lighting windows 202; therefore, when at least two cameras are arranged in the lighting window 202 in a corresponding surrounding manner, the distance between the cameras can be reduced.
The display screen comprises a luminescent layer 10 and a drive circuit layer 20; the light-emitting layer 10 includes at least two display units 101, and a lighting window 202 is disposed at a position on the driving circuit layer 20 opposite to the display units 101, so that at least two cameras in the under-screen camera module collect information to be shot through the lighting window 202; at least two driving units 201 corresponding to the at least two display units 101 one to one are arranged on the driving circuit layer 20, and each driving unit 201 comprises a first driving circuit 2011 and a second driving circuit 2012; the first driving circuit 2011 and the second driving circuit 2012 on each driving unit 201 are respectively located at two sides of the light-emitting window 202, and the arrangement direction of at least two driving units 201 is consistent with the arrangement direction of at least two display units 101. Because the driving circuit layer 20 of the display screen is provided with the light opening window at the position corresponding to the display unit 101, at least two cameras arranged below the display screen can acquire information to be shot through the light collecting window 202 and the display unit 101; further, since the at least two driving units 201 corresponding to the at least two display units 101 one to one are disposed on the driving circuit layer 20, and the driving unit 201 includes the first driving circuit 2011 and the second driving circuit 2012, when the first driving circuit 2011 and the second driving circuit 2012 are respectively located at two sides of the lighting window 202, the magnitude of the driving current provided by the first driving circuit 2011 and the second driving circuit 2012 to the display units 101 can be more uniform, and the display uniformity effect of the display units 101 is improved; finally, since the arrangement direction of the driving unit 201 is the same as that of the display unit 101, the driving circuit of the display unit 101 does not exist between the positions corresponding to the at least two cameras in the driving circuit layer 20, so that the distance between the at least two cameras can be reduced, and the shooting effect of the terminal device is improved.
In one embodiment, on the basis of the above embodiment, as shown in fig. 3, at least two linearly arranged light collecting windows 202 are opened at positions of the driving circuit layer 20 facing the display units 101, and an arrangement direction of the light collecting windows 202 is consistent with an arrangement direction of at least two display units 101. When the terminal equipment sets the display screen, each lighting window 202 in the driving circuit layer 20 corresponds to one camera, so that the multiple cameras can collect information to be shot through the corresponding sampling windows and the corresponding display units 101, and interference when the cameras collect light is reduced.
The arrangement direction of the lighting windows 202 may be along the horizontal direction of the display screen, or along other linear directions in the display screen, which is not limited herein. Alternatively, the lighting windows 202 are arranged in the vertical direction of the display screen. When the light emission windows 202 are arranged in the vertical direction of the display screen, the first drive circuit 2011 and the second drive circuit 2012 corresponding to each display unit 101 are arranged horizontally on both sides of the light emission windows 202. Therefore, the lighting window 202 may be as close to the top of the display screen as possible; correspondingly, above-mentioned two at least display element 101 can be located the top of display screen, reserves sufficient space for terminal equipment's mainboard and battery to can reduce the mainboard wiring degree of difficulty, and make terminal equipment can have the battery of great capacity, promote terminal equipment's duration.
In an embodiment, on the basis of the above embodiment, as shown in fig. 4, a runway window is disposed at a position on the driving circuit layer 20 opposite to the display unit 101, and an extending direction of the runway window is consistent with an arrangement direction of at least two display units 101. When the terminal device is provided with the display screen, each lighting window 202 in the driving circuit layer 20 can collect information to be shot through the runway window and the corresponding display unit 101, so that the two adjacent cameras are not blocked by the driving circuit layer 20 and can be close to each other, the distance between at least two cameras is further reduced, the shooting effect under partial scenes can be improved, and the adaptability of the terminal device to the shooting scenes is enhanced.
The extending direction of the runway window may be along the horizontal direction of the display screen, or along other linear directions in the display screen, which is not limited herein. Optionally, the runway window extends in a vertical direction of the display screen. In the case where the racetrack window extends in the vertical direction of the display screen, the first drive circuit 2011 and the second drive circuit 2012 corresponding to each display cell 101 are horizontally arranged on both sides of the racetrack window. Therefore, the runway window can be as close to the top of the display screen as possible; correspondingly, above-mentioned two at least display element 101 can be located the top of display screen, reserves sufficient space for terminal equipment's mainboard and battery to can reduce the mainboard wiring degree of difficulty, and make terminal equipment can have the battery of great capacity, promote terminal equipment's duration.

In the display panel, the first pixel unit 1011 and the second pixel unit 1012 are divided by the central axis of the display unit 101, that is, the number of light emitting pixels included in the first pixel unit 1011 and the second pixel unit 1012 is substantially the same. The first driving circuit 2011 is used for driving the first pixel unit 1011 to emit light, and the second driving circuit 2012 is used for driving the second pixel unit 1012 to emit light, so the number of integrated circuits arranged in the first driving circuit 2011 and the second driving circuit 2012 is also approximately the same. Since the lighting window 202 is provided at a position corresponding to the display unit 101, the central axis of the lighting window 202 and the central axis of the display unit 101 are located at the same position on the corresponding plane. The first driving circuit 2011 is located on one side of the central axis of the lighting window 202, and the second driving circuit 2012 is located on the other side of the central axis of the lighting window 202, so that the connecting line between the driving unit 201 and the electrode of each light-emitting pixel can be as short as possible, and the length of the connecting line can be set within a preset range, so that the driving current of each light-emitting pixel is consistent, and the display consistency of the display screen is improved.
