Are recognized as the most promising display screens. OLEDs are classified into Passive Matrix OLEDs (PMOLEDs) and Active Matrix Organic Light Emitting Diodes (AMOLEDs) according to driving methods. The AMOLED display screen is internally provided with a plurality of pixels which are arranged in an array mode, and each pixel is driven through a pixel driving circuit. For terminal equipment such as mobile phones, tablet computers and notebook computers, the terminal equipment has a display function and a shooting function, if a camera used for shooting is placed below a display screen used for displaying pictures, an area specially used for placing the camera does not need to be vacated on a panel of the terminal equipment, the panel space can be saved, and a real 'full-screen' (no punching, grooving and the like) is realized. A a plurality of pixels that are arranged for having the array in the display screen of display frame, when placing the camera below the display screen, in order not to influence the normal use of camera, the pixel quantity in the region that corresponds with the camera on the display screen needs to reduce to promote the panel transmissivity. However, the reduction may cause the number of pixels in the area corresponding to the camera to be uneven with the number of pixels in other areas, and color lines may appear at the edge of the area corresponding to the camera, which may affect the appearance.
In the prior art, in order to weaken the color lines, a Sub Pixel Rendering (SPR) algorithm is used for the light emission compensation process. However, since the SPR algorithm performs compensation processing by using the neighboring pixels, the above method can solve the problem of color lines at the edge of the region corresponding to the camera, and for the edge which is not bordered by other regions, the problem of color lines still cannot be solved.

Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In this application, it should be construed that the terms "first," "second," and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Further, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "is a relationship generally indicating that the former and latter associated objects are an" or ". "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a alone, b alone, c alone, a and b combination, a and c combination, b and c combination, or a, b and c combination, wherein a, b and c can be single or multiple.
The camera technique under the screen is the key technique of realizing the full face screen, when placing the camera below the display screen, in order not to influence the normal use of camera, the pixel quantity that the camera corresponds the region on the display screen needs to reduce. For example, referring to the display screen shown in FIG. 1, the display screen may be divided into 18 rows and 16 columns. Three small squares constitute one pixel, such as: the area corresponding to row 18, column 1 in fig. 1 comprises three small squares, which form one pixel, and for example, the area corresponding to row 17, column 4 in fig. 1 also comprises three small squares, which form one pixel. Each small square grid can correspond to a sub-pixel, each sub-pixel corresponds to a color, and the colors of the three sub-pixels in the 18 th row and the 1 st column in fig. 1 can be red, green and blue in sequence from left to right.
On the display screen shown in fig. 1, the area corresponding to the Line number range Line5-Line18 and the column number range 3-14 is the area corresponding to the camera, and the number of pixels in the area is obviously smaller than that in the area outside the area, because the camera needs to collect the off-screen image through the blank area in the area, thereby realizing the shooting function. Because the number of pixels in the corresponding area of the camera on the display screen is reduced, the pixel distribution in the corresponding area of the camera and the pixel distribution in other areas are uneven, and colored lines, such as green lines, can appear at the edge of the corresponding area of the camera, so that the appearance is influenced.
In the prior art, in order to weaken the color lines, a Pixel Rendering (Sub Pixel Rendering) SPR algorithm is used for the light emission compensation process. The SPR algorithm is compensated by the side pixels, for example: with reference to fig. 1, when a green Line appears at the left edge of the corresponding area of the camera, the green Line can be weakened by the red sub-pixels and/or the blue sub-pixels in the column 2 and the Line number range Line5-Line18, so as to achieve the effect of equalizing the display effect; when a green line appears at the lower edge of the corresponding area of the camera, the green line can be weakened by the red sub-pixels and/or the blue sub-pixels in the 4 th row and the column number range of 3-14; when a green Line appears at the right edge of the corresponding area of the camera, the green Line can be weakened by the red sub-pixels and/or the blue sub-pixels in the 15 th column and the Line number range of Line5-Line 18. However, as shown in fig. 1, there are pixels available beside the left, right and lower edges of the corresponding area of the camera, so the above method can solve the problem of color lines at these edges, and the problem of color lines still cannot be solved for edges which are not bordered by other pixels, such as the upper edge of the corresponding area of the camera.
It should be noted that: the above example illustrates the principle of weakening the color line by taking the green line as an example, and similarly, when the edge generates a red line, the red line can be weakened by the adjacent green sub-pixel and/or blue sub-pixel; when the edge generates a blue line, the blue line can be attenuated by the adjacent red and/or green sub-pixels, and the positions of the pixels can be referred to the above-mentioned example of the green line, and the present invention will not be described in detail herein.
In order to solve the problem that the color lines appear on the upper edge, the invention provides a display screen, the corresponding area of a camera is shifted down by one or more pixels, after the downward shifting processing, the upper edge is also provided with the pixels which can be used, and the SPR algorithm can perform compensation processing on the upper edge by the pixels, so that the problem of the color lines on the upper edge is solved. After the corresponding area of the camera is moved downwards, pixels above the corresponding area of the camera need to be lightened, in order to lighten the pixels and ensure the transmittance of the corresponding area of the camera, the invention provides that the lightening of the corresponding pixels is realized by changing the arrangement of signal lines, so that the display screen of the invention solves the problem of color lines and ensures the transmittance of the corresponding area of the camera.
The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic structural diagram of a display screen according to a first embodiment of the present invention. As shown in fig. 2, the display screen provided in this embodiment includes: the display device comprises a transparent display area 10 and a regular display area 11, wherein the transparent display area 10 is surrounded by the regular display area 11, the transparent display area 10 comprises at least one strip-shaped light-transmitting area 101 and at least one strip-shaped display area 102, and the at least one strip-shaped light-transmitting area 101 and the at least one strip-shaped display area 102 are arranged at intervals. The at least one strip-shaped light-transmitting area 101 is used for the camera under the screen to collect images through the at least one strip-shaped light-transmitting area 101, and the at least one strip-shaped display area 102 and the conventional display area 11 are used for displaying pictures.
It should be noted that: the transparent display area 10 in the present embodiment refers to the camera corresponding area described above. The at least one bar-shaped display area 102 and the regular display area 11 each comprise an array of pixels. Since the at least one strip-shaped light-transmitting area 101 is used for the under-screen camera to acquire images, pixels may not be arranged in the at least one strip-shaped light-transmitting area 101. The pixel array in each stripe display area 102 may include a plurality of pixels arranged at intervals, and the density of the pixels in each stripe display area 102 may be flexibly set according to actual conditions. Such as: two adjacent pixels in the strip-shaped display area are separated by a distance of one pixel, or two adjacent pixels are separated by a distance of a plurality of pixels.
For example, the transparent display area 10 is shifted down by two pixels from the position shown in fig. 1 in fig. 2, it is understood that the transparent display area 10 may be shifted down by one pixel or shifted down by more than two pixels, and the invention is not limited thereto.
The weakening principle when colored lines appear at the upper edge of the transparent display area 10 is explained below with reference to fig. 2:
the transparent display area 10 in fig. 2 is shifted down by two pixels compared to the corresponding area of the camera shown in fig. 1, so that two lines of pixels Line17 and Line18 appear above the transparent display area 10. When a green line appears at the upper edge of the transparent display area 10, the green line can be attenuated by means of the red and/or blue sub-pixels in the 17 th row, column number range 3-14; similarly, when a red line appears at the upper edge of the transparent display area 10, the red line can be attenuated by the blue and/or green sub-pixels in the 17 th row, column number range 3-14; when a blue line appears at the upper edge of the transparent display area 10, it can be attenuated by means of the red and/or green sub-pixels in the 17 th row, column number range 3-14. It can be seen that by designing the transparent display area 10 in the manner shown in fig. 2, the problem of color lines appearing at the upper edge of the transparent display area 10 can be solved.
For example, in fig. 2, the transparent display area 10 includes 5 bar-shaped light-transmitting areas 101, 4 bar-shaped display areas 102, and the 5 bar-shaped light-transmitting areas 101 and the 4 bar-shaped display areas 102 are arranged at intervals, it is understood that the number of the bar-shaped light-transmitting areas 101 and the number of the bar-shaped display areas 102 may be other numbers, and the invention is not limited thereto.
For example, in fig. 2, the pixel array in each stripe display area 102 includes 7 pixels arranged at equal intervals, and the number of the pixels arranged in the pixel array in each stripe display area 102 may also be other numbers, which is not limited in the present invention.
The principle of light emission of each pixel on the display screen is described as follows:
the bottom end of the display screen is provided with a driving chip, the number of signal lines in the driving chip is matched with the number of columns of the pixel array in the conventional display area 11, as shown in fig. 3, the number of columns of the pixel array in the conventional display area 11 of the display screen is 16, and since each pixel comprises three sub-pixels, each column of the pixel array is divided into three columns, the number of signal lines in the driving chip is three times that of the columns of the pixel array, namely 48 signal lines. One signal line corresponds to each column of sub-pixels. Conventionally, the connection mode between each column of sub-pixels and the corresponding signal line is as follows: taking the column 1 in fig. 3 as an example, since each pixel in the column 1 includes three sub-pixels, the first column is further divided into three columns, each column corresponds to one signal Line, the signal lines are used as main lines and are arranged to the Line18 Line by Line along the arrow direction from the driving chip, so that each sub-pixel of the Line1-Line18 can be connected to the corresponding signal Line to emit light under the control of the electrical signals transmitted by the signal lines.
However, after the transparent display region 10 is shifted down, the pixels in the same column as the strip-shaped light-transmitting region 101 need to be lighted up to realize the picture display. As shown in fig. 3, after the transparent display region 10 moves down, the Line number range is Line17-Line18, and the regions corresponding to the column number ranges of 3, 5, 6, 8, 9, 11, 12, and 14 need to be lit up, according to the general practice, taking the 3 rd column in fig. 3 as an example, the corresponding signal lines need to be arranged to Line18 Line by Line, and in this way, the signal lines will pass through the strip-shaped light-transmitting region 101, which affects the transmittance of the strip-shaped light-transmitting region 101, so that the camera cannot normally operate.
In order to solve this technical problem, the present embodiment divides the normal display area 11 into two areas as shown in fig. 4: the first region is a region which is far away from one end of the driving chip in the conventional display region 11 and is in the same column as the strip-shaped light-transmitting region 101, namely, the Line number range is Line17-Line18, and the column number range is 3, 5, 6, 8, 9, 11, 12 and 14 in fig. 4. The second area is an area other than the first area in the normal display area 11. In order not to affect the transmittance of the strip-shaped light-transmitting area 101, in the second area, the signal lines in the second area are arranged along the direction away from the driving chip, and in the first area, the signal lines in the second area are arranged along the direction close to the driving chip. So that the light emission of the first region is not controlled by the signal lines of the corresponding columns any more, but is controlled by the signal lines of the second region by extending the signal lines of the second region to the first region. Thereby achieving the purposes of not affecting the transmittance of the light-transmitting area and solving the problem of color lines.
Each sub-pixel in fig. 4 corresponds to a pixel driving circuit for driving the sub-pixel to emit light, and optionally, the pixel driving circuit corresponding to each sub-pixel in fig. 4 may be any one of a 2T1C circuit, a 3T1C circuit, a 6T1C circuit, a 6T2C circuit, a 7T1C circuit, a 7T2C circuit, or a 9T1C circuit. In this document, the "2T 1C circuit" refers to a pixel circuit including 2 thin film transistors (T) and 1 capacitor (C) in a pixel driving circuit, and the rest of "7T 1C circuit", "7T 2C circuit", "9T 1C circuit", and so on, and the internal design structure of each type of circuit can be referred to the prior art, and the description of the present invention is omitted herein.
In one possible implementation, referring to fig. 4A, the driving chip in this embodiment may be a Data driving chip, and signal lines led out from the Data driving chip are used to provide Data signals for the respective sub-pixels, such as the signal lines D1, D2, D3, and D4 in fig. 4A.
Optionally, the display screen provided by this embodiment may further include a scan driving chip, and signal lines led out from the scan driving chip are used for providing Gate signals for the respective sub-pixels, such as the signal lines S1, S2, S3, and S4 in fig. 4A.
In a possible implementation manner, for a target strip-shaped light-transmitting region at an edge position in at least one strip-shaped light-transmitting region 101, light emission of a region in the same column as the target strip-shaped light-transmitting region 101 in the first region may be controlled by a signal line of a region formed by pixels in a column adjacent to the target strip-shaped light-transmitting region 101 in the second region.
Referring to fig. 4, the target strip-shaped light-transmitting regions at the edge positions in the at least one strip-shaped light-transmitting region 101 are strip-shaped light-transmitting regions in the 3 rd column and strip-shaped light-transmitting regions in the 14 th column, and for the strip-shaped light-transmitting regions in the 3 rd column, the light emission of the region corresponding to the Line number range of Line17-Line18 and the column number range of 3 can be controlled by the signal lines of the region constituted by the 2 nd column of pixels. For the strip-shaped light-transmitting region in the 14 th column, the Line number range is Line17-Line18, and the light emission of the region corresponding to the 14 th column number range can be controlled by the signal Line of the region constituted by the 15 th column of pixels.
Taking the area constituted by the 2 nd column of pixels as an example, since the three signal lines in this area are to control the light emission of the sub-pixels of the respective colors of the 2 nd column Line1-Line18 and the light emission of the sub-pixels of the respective colors of the 3 rd column Line17-Line18, the electric signals transmitted by the three signal lines in this area include both the electric signal for controlling the light emission of the sub-pixels of the respective colors of the 2 nd column Line1-Line18 and the electric signal for controlling the light emission of the sub-pixels of the respective colors of the 3 rd column Line17-Line18, which is equivalent to adding the control signals of two rows of pixels in time sequence, such as the Line19-Line20 circled in fig. 5, and the added control signals are actually used for controlling the light emission of the sub-pixels of the respective colors of the 3 rd column Line17-Line 18. In FIG. 5, Source2-R indicates the signal line for the red sub-pixel in column 2, Source2-G indicates the signal line for the green sub-pixel in column 2, and Source2-B indicates the signal line for the blue sub-pixel in column 2.
According to the display screen provided by the embodiment, the corresponding area of the camera is shifted down by one or more pixels, after the downward shift processing, the upper edge is also provided with the pixels which can be used for the assistance, and the SPR algorithm can perform compensation processing on the upper edge by means of the pixels, so that the problem of color lines at the upper edge is solved.
