Detailed Description
Fig. 1 is a schematic structural diagram of a conventional display panel. As shown in fig. 1, a substrate 100 of the display panel includes a display area 110 and a wiring area 120, wherein a plurality of pixel rows are distributed on the display area 110, and each pixel row is composed of a plurality of pixels 111 arranged according to a certain rule. Signal lines and a driver circuit for controlling and driving the pixels 111 in the display region 110 to emit light are arranged on the wiring region 120.
In the prior art, the wiring area 120 needs to be provided with a pixel row driving circuit 112 corresponding to each pixel row, and each pixel row driving circuit 112 will provide a driving signal for the pixels 111 of the corresponding pixel row to control the pixels 111 to emit light. And driving signals for driving the pixel row driving circuits 112 to operate are transmitted between the pixel row driving circuits 112 in the directions indicated by arrows in fig. 1. That is, the scanning driving of the display region 110 is completed by repeating the process of inputting from the pixel row driving circuit 112 corresponding to the first row of pixel rows, outputting after passing through each pixel 111 of the first row of pixel rows, inputting from the pixel row driving circuit 112 corresponding to the next row of pixel rows, and outputting after passing through each pixel 111 of the next row of pixel rows.
With the development trend of narrow-edge design of intelligent terminals, a layout mode of arranging cameras in a display area of a display panel to reduce the size of a frame becomes the mainstream. For example, as shown in fig. 1, the off-screen camera 130 is disposed in the display area 110 in such a way that the pixels 111 in the display area are no longer uniformly distributed, i.e., a part of the pixels 111 in the display area is removed for the convenience of disposing the off-screen camera 130.
However, such an arrangement would cause the number of pixels in each pixel row to no longer remain uniform. When the driving signal drives the pixels 111 in each pixel row to emit light, the load of each pixel row is uneven due to the inconsistency of the number of the pixels, which causes the phenomenon of inconsistent pixel brightness in each pixel row, resulting in the problem of brightness mura and seriously affecting the display quality of the display panel.
In view of the above technical problems, how to improve the display quality of the display panel provided with the off-screen camera is a problem to be solved urgently.
The technical solution of the present invention and how to solve the above technical problems will be described in detail with specific embodiments below. The following several embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The display panel in the embodiment of the invention can be a display only having a display function, and can also be a display panel capable of providing an operation interaction function. In addition, the display panel may be a flexible panel having a folding, bending or curling function, or may be a conventional panel having no folding, bending or curling function. Of course, as the technology advances, the display panel can also be a panel of various new forms.
Fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention. As shown in fig. 2, in this embodiment, the display panel includes at least a substrate 100.
The substrate 100 includes a display region 110 and a wiring region 120 located around the display region 110, and the display region 110 includes a plurality of pixel rows each of which is composed of a plurality of pixels 111. The display area 110 includes a first display area 1101 and a second display area 1102, and the number of pixels in pixel rows in different display areas is different.
The wiring region 120 is provided with pixel row driving circuits 112 corresponding to the respective pixel rows one by one; the pixel row driving circuit 112 for driving each pixel row in the first display region uses the first driving signal, and the pixel row driving circuit 112 for driving each pixel row in the second display region uses the second driving signal.
Different from the prior art, in the scheme provided in this embodiment, different driving signals are used for driving the display regions with different pixel distribution conditions in the display panel, so that different driving signals are used for driving the pixel rows in the display regions in the display panel in the respective display regions with different pixel distribution conditions, and the problem of brightness mura caused by inconsistent pixel brightness of the pixel rows in the display panel due to the use of a single driving signal is solved.
The structure and implementation of the display panel provided by this embodiment will be further described below:
in the display panel provided in the present embodiment, the substrate 100 may be formed of various materials (e.g., glass, plastic, etc.), and may be formed of different materials according to the type of the display panel. For example, when the display panel is a flexible panel, the substrate 100 may be formed using a flexible material (e.g., polyimide plastic, etc.).
The size of the display area 110 included in the substrate 100 and the position on the substrate 100 can be determined according to actual use requirements or design requirements. The plurality of pixels 111 in the same pixel row in the display area 110 may be pixels of the same color or pixels of different colors, and when the pixels are pixels of different colors, the arrangement of the pixels of different colors may be any manner, which is not limited in this embodiment.
The substrate 110 further includes a wiring region 120, and the wiring region 120 is located around the display region 110, i.e., the wiring region 120 is a region of the substrate 110 other than the display region 110. The wiring region 120 includes a power supply, signal lines, a driver circuit corresponding to each signal, and the like.
The display panel specifically includes a plurality of pixel row driving circuits 112 located in the wiring area 120. Each pixel row driving circuit 112 should be disposed corresponding to each pixel row in the display area 110, and further, the pixel row driving circuit 112 may be a gate driving circuit, for example, providing a gate driving signal for one or more pixel rows. The Gate driving circuit may be a GIP circuit (Gate-In-Panel circuit, i.e., an In-Panel Gate driving circuit).
In one example, the gate driving circuit may include a scan driving circuit (also referred to as a "scan circuit") and an EM circuit (also referred to as a "light emission control circuit") which may be used to provide driving signals for the pixel rows connected thereto to enable control of the operating state of each pixel row.
In the present embodiment, the display area is divided into different display areas based on the pixel distribution in the display area.
For example, fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention. An aperture area is provided in the upper area of the display area 110, and the area (upper area) where each pixel line straddled by the aperture area is located serves as the second display area 1102 of the display panel, and the area (lower area) where each pixel line not straddled by the aperture area is located serves as the first display area 1101, wherein in an actual display device, the aperture area may have the off-screen camera 130 placed therein, but of course, other structures such as an off-screen sensor, an off-screen fingerprint recognition device, and the like may be placed therein. In other optional embodiments, the hole region may also be disposed in the first display region 1101, and a detailed implementation manner thereof is not described in detail.
It should be noted that the number of the first display area 1101 and the second display area 1102 may be determined based on actual requirements, and may be one or more, which is not limited in this embodiment.
In the configuration shown in fig. 2, a portion of pixels 111 in each pixel row of the second display region 1102 will need to be removed due to the presence of the aperture region (i.e., the off-screen camera 130). That is, the number of pixels per pixel row in the first display region 1101 will be greater than the number of pixels per pixel row in the second display region 1102.
The pixel row driving circuit in the first display area 1101 drives each pixel row in the first display area 1101 to emit light for display based on the first driving signal EIN1, and the pixel row driving circuit in the second display area 1102 drives each pixel row in the second display area 1102 to emit light for display based on the second driving signal EIN 2.
As shown in fig. 2, the second driving signal EIN2 is input from the pixel row driving circuit corresponding to the first row of pixel rows in the second display region 1102, so that the pixel row driving circuit corresponding to the first row of pixel rows controls the first row of pixel rows to emit light under the driving of the second driving signal EIN 2; meanwhile, the second driving signal EIN2 is outputted from one end (the left end as shown in fig. 2) of the pixel row and is transmitted to the pixel row driving circuit of the next row of pixel rows, so that the pixel row driving circuit corresponding to the next row of pixel rows controls the next row of pixel rows to emit light under the driving of the second driving signal EIN2, and the process is repeated until the next row of pixel rows in the second display area 1102 is outputted.
Similarly, a first driving signal EIN1 is input from the pixel row driving circuit corresponding to the first row of pixel rows in the first display area 1101, so that the pixel row driving circuit corresponding to the first row of pixel rows controls the first row of pixel rows to emit light under the driving of the first driving signal EIN 1; meanwhile, the first driving signal EIN1 is outputted from the other end (the right end as shown in fig. 1) of the pixel row, and is transmitted to the pixel row driving circuit of the next row of pixel rows, so that the pixel row driving circuit corresponding to the next row of pixel rows controls the next row of pixel rows to emit light under the driving of the first driving signal EIN1, and the process is repeated until the next row of pixel rows is outputted from the end row of the first display area 1101.
In order to make the pixel brightness of each pixel row in the display area the same, in an alternative embodiment, the pixel rows may be controlled to emit light with different light-emitting time periods by controlling the high-low level distribution in the driving signal. In general, when the light emission time period is short, the pixel luminance of the pixel row is low, and when the light emission time period is long, the pixel luminance of the pixel row is high.
Specifically, in this embodiment, the first driving signal is used to drive the pixel row driving circuit to make each pixel row in the first display area 1101 emit light with a first light-emitting duration, and the second driving signal is used to drive the pixel row driving circuit to make each pixel row in the second display area 1102 emit light with a second light-emitting duration; under the drive of the first drive signal and the second drive signal, the pixel brightness of each pixel row in the display area is the same. That is, the pixel brightness of each pixel line in the second display region 1102 having the aperture region (the lower-screen camera 130) is made the same as the pixel brightness of each pixel line in the first display region 1101 not having the aperture region (the lower-screen camera 130).
When the number of pixels in a pixel row is smaller (e.g., the pixel row corresponding to the second display region 1102 shown in fig. 2), the load of the pixel row is smaller; when the number of pixels in a pixel row is larger (e.g., the pixel row corresponding to the first display region 1101 shown in fig. 2), the load of the pixel row is larger. When the first display area 1101 and the second display area 1102 are driven by the same driving signal, the pixel rows in the first display area 1101 look darker, i.e., the pixel brightness is lower, due to the complex difference; while the rows of pixels in the second display region 1102 appear brighter, i.e., have higher pixel brightness.
In order to make the pixel brightness of each pixel row in the display area the same, in an optional embodiment, the low-level time in the driving signal may be adjusted by using a characteristic that the light-emitting time of the pixel row is proportional to the low-level time in the driving signal, and the pixel brightness of the first display area 1101 and the pixel brightness of the second display area 1102 are adjusted by adopting a setting mode of the driving signal in which the low-level time in the first driving signal is greater than the low-level time in the second driving signal, so that the pixel brightness of the first display area 1101 and the pixel brightness of the second display area 1102 are kept the same, thereby improving the mura phenomenon of the display panel and improving the display quality.
In other alternative embodiments, fig. 3 is a schematic structural diagram of another display panel provided in the embodiments of the present invention. In addition to the structure shown in fig. 2, the wiring region 120 is further provided with a first driving signal line 121 and a second driving signal line 122; the first driving signal lines 121 and the second driving signal lines 1222 are distributed in parallel in the wiring region 120; wherein the first driving signal is input to the first display region 1101 through the first driving signal line 121; the second driving signal is input to the second display region 1102 through the second driving signal line 122.
Specifically, as shown in fig. 3, two first display regions 1101 and one second display region 1102 are included in the display panel. For the convenience of routing, the first driving signal line 121 may be disposed around the display region 110, so that the pixel row driving circuit corresponding to the first row of pixel rows of the first display region 1101 may be electrically connected thereto, and receive the first driving signal transmitted therefrom; correspondingly, the second driving signal line 122 may also be correspondingly wound around the display area 110 and disposed in parallel with the first driving signal line 121, so that the pixel row driving circuit corresponding to the first row of pixel rows of the second display area 1102 may be electrically connected thereto.
Further, the first driving signal line 121 is connected to the pixel row driving circuit of the first row of pixel rows in the first display area 1101, so that the first driving signal is input from the pixel row driving circuit 112 of the first row of pixel rows, output from the first row of pixel rows and input to the pixel row driving circuit 112 of the next row of pixel rows, until output from the last row of pixel rows in the first display area 1101; the second driving signal line 121 is connected to the pixel row driving circuit 112 of the first row of pixel rows in the second display region 1102, so that the second driving signal is input from the pixel row driving circuit 112 of the first row of pixel rows, output from the first row of pixel rows, and input to the pixel row driving circuit 112 of the next row of pixel rows, until output from the last row of pixel rows in the second display region 1102.
Of course, alternatively, the output ends of the last row of pixel rows in the first display area 1101 and/or the second display area 1102 are arranged in a floating manner, so as not to affect the driving of the pixel rows by the pixel row driving circuits of the next row.
It should be noted that, as shown in fig. 4, no matter the first driving signal or the second driving signal is a signal timing diagram of a display panel provided by the embodiment of the present invention, it should satisfy a basic condition that the pixel rows can be driven to normally display light, that is, a time length of the pixel row driving circuit in the off state needs to be longer than a sum of a time length of the initialization stage of the display panel and a time length of the data read/write stage, so that after the initialization stage and the data read/write stage of the display panel are completed, the pixel row driving circuit is turned to the on state, thereby implementing normal operation of the display panel.
In particular, the signal timing diagram of the driving signals shown in fig. 4 is shown, in which the pixel row driving circuit is in an off state when the first driving signal and the second driving signal are at a high level, and the pixel row driving circuit is in an on state when the first driving signal and the second driving signal are at a high level. Of course, in other implementations, the correspondence between the level in the driving signal and the state of the switch in the pixel row driving circuit may be different based on the different switch types in the pixel row driving circuit. That is, in actual use, there may be a case where the drive signal is at a low level and the switch in the pixel row drive circuit is in an off state. The above-mentioned specific setting modes are prior art in the field, and this embodiment will not be described in detail.
In other alternative embodiments, fig. 5 is a schematic structural diagram of another display panel provided in the embodiments of the present invention. In addition to the structure shown in fig. 2 or 3, the wiring region 120 of the display panel is further provided with a first anti-static circuit 123 and a second anti-static circuit 124;
the first driving signal is input to the first display area 1101 through the first anti-static circuit 123; a second driving signal is input to the second display region 1102 through the second anti-static circuit 124.
In this embodiment, in order to prevent the panel circuit from being broken down by static electricity, an anti-static circuit is required to be disposed at the input end of the driving signal. Specifically, the driving signal passes through the anti-static circuit and then enters the pixel row driving circuit along the driving signal line. Fig. 5 shows the signal flow direction of the first driving signal and the second driving signal on the first driving signal line 121 and the second driving signal line 122, respectively, that is, the first driving signal flows into the first display region 1101 and the second driving signal flows into the second display region 1102 through the first anti-static circuit 123 and the second anti-static circuit 124.
In addition, in order to further reduce the size of the wiring area 120, the pixel row driving circuits in different display areas will share the same clock signal and data signal. That is, the wiring region 120 is also provided with a clock signal line and a DATA signal line (CK/DATA shown in fig. 5); wherein, the clock signal is respectively input to the first display region 1101 and the second display region 1102 through the clock signal line; data signals are input to the first display region 1101 and the second display region 1102 through the data signal lines, respectively.
In addition, the invention also provides a display device, a display panel according to any one of the embodiments of fig. 2 to 4, and an off-screen camera; the camera under the screen is arranged in the first display area or the second display area of the display panel and is arranged in a pixel flat layer mode in the display area.
The invention also provides a driving method of the display panel, which comprises the following steps:
step 101, respectively determining the number of pixels in a pixel row in a first display area and the number of pixels in a pixel row in a second display area;
102, generating a first driving signal and a second driving signal according to the number of pixels of the first display area and the number of pixels of the second display area;
and 103, driving the pixel rows corresponding to the pixel row driving circuits in the first display area to emit light by adopting the first driving signal, and driving the pixel rows corresponding to the pixel row driving circuits in the second display area to emit light by adopting the second driving signal.
For the implementation manner of determining the driving signal based on the number of pixels in step 102, reference may be made to the description of the foregoing embodiments, which is not described in detail in this embodiment.
