Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of display screen correction, and in particular to a method for adjusting the brightness of a display screen and an electronic device. Background Art

[0002] LED display screens are generally composed of multiple LED light panels or cabinets. However, due to production processes or on-site arrangements, there will often be differences in the spacing between the splicing gaps between LED light panels or cabinets. If the spacing is too large, the display brightness of the gaps between the light panels or cabinets will be lower than the display brightness of the light panels. If the spacing is too small, the display brightness of the gaps between the light panels or cabinets will be higher than the display brightness of the light panels, which will affect the display effect of the LED display screen.

[0003] At present, the repair technology between the gaps of LED display screens has gradually matured, but the method of manually adjusting the gaps still needs to be improved. Manually adjusting the gaps is to determine the position of the LED light points by displaying the specified background image and foreground gap lines on the LED screen. The human eye increases or decreases the gap repair value according to the brightness of the current gap display to adjust the brightness of the LED lamp beads corresponding to the gap to a level that the human eye cannot feel. However, the conventional manual gap adjustment method is not accurate enough to repair the intersection of the light board or cabinet gap, and there will still be display differences.

[0004] At present, the problem of uneven display effect of gaps on LED screens is usually solved by adjusting the brightness intensity per unit area, which may lead to display differences due to insufficient adjustment of the gap intersection points. Summary of the invention

[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] It should be noted that, if there is no conflict, the various features in the embodiments of the present application can be combined with each other, and all are within the scope of protection of the present application. In addition, the words "first", "second", "third", etc. used in the present application do not limit the data, but only divide the same or similar items with basically the same functions and effects.

[0063] The technical solution of the present application is described in detail below in conjunction with the accompanying drawings:

[0064] See also Figure 1 , Figure 1 is a schematic diagram of an application environment provided by an embodiment of the present application;

[0065] like Figure 1 As shown, the application environment 100 includes: a display device 10 and an electronic device 20, wherein the display device 10 is used to display the screen of the electronic device 20, the electronic device 20 is used to correct the display screen of the display device 10, and the display device 10 and the electronic device 20 are connected via a wired interface. It can be understood that the electronic device 20 includes network-capable devices such as tablet computers and computer terminals, the display device 10 includes devices that can display screens such as LED displays, LCD displays, and CRT displays, and the wired interface includes USB, HDMI, VGA, DVI, DisplayPort and other interfaces.

[0066] In the embodiment of the present application, the display device includes a device capable of displaying images, such as an LED display, an LCD display, a CRT display, etc. The display device provides a wired interface for the electronic device 20 to obtain and identify parameter information of the display device, thereby enabling the electronic device 20 to control the display device.

[0067] Before introducing the solution of the present application, a brief introduction to the prior art known to the inventor of the present application is first given to facilitate subsequent understanding of the solution of the present application.

[0068] Automatically adjust the gap: Use a camera or other tools to accurately determine the distance of the gap and automatically adjust the gap coefficient of the display lamp beads corresponding to the gap.

[0069] Manually adjust the gap: Determine the position of the display screen lamp beads by turning on the screen (displaying the specified background image and foreground gap line). The human eye determines the brightness of the lamp beads in the current gap to increase or decrease the gap correction coefficient, and further adjust the brightness of the display screen lamp beads corresponding to this gap, so that the human eye cannot feel the inconsistent brightness of the lamp beads on the display screen.

[0070] Screen: Use the view area in the software on the electronic device to display the current screen's light board or cabinet simulation diagram, click the gap between the light board or cabinet in the current screen, and then notify the actual display screen to flash the lamp beads at the gap location to confirm the gap location. The way to notify the gap location can be video signal notification, or send the location to the LED control system, and the LED control system will flash to notify.

[0071] In some prior arts, the intersection points of the gaps are divided separately. For example, the lamp beads at the lower left corner of the light board are divided into horizontal lines, the lamp beads at the upper left corner of the light board are divided into vertical lines, the lamp beads at the upper right corner of the light board are divided into horizontal lines, and the lamp beads at the lower right corner of the light board are divided into vertical lines. Usually, the horizontal line gap or the vertical line gap is adjusted first, and the horizontal line gap and the vertical line gap are not adjusted at the same time. Therefore, when adjusting one of the horizontal line gap and the vertical line gap, only half of all the gap intersection points can be adjusted. Adjacent gap intersection points may have inconsistent brightness, but there will be no obvious brightness difference between the brightness of the gap intersection points and the brightness of the lamp beads inside the light board.

[0072] In some prior arts, when using the manual gap adjustment method, it is necessary to select the gap intersection points individually and adjust the brightness one by one. Although this method can be adjusted arbitrarily according to user needs, when the display screen is too large and the number of adjustments is too many, individually selecting and adjusting the gap intersection points is not only cumbersome to operate, but also brings a large workload to the staff, reducing work efficiency.

[0073] In the embodiments of the present application, the solution provided by the present application can solve the problem in the prior art that there is a significant brightness difference between the brightness of the intersection of the gaps and the brightness of the lamp beads inside the lamp board, and the problem that the intersection of the gaps needs to be selected separately for brightness adjustment.

[0074] See also Figure 2 , Figure 2 It is a flow chart of a method for adjusting the brightness of a display screen provided in an embodiment of the present application;

[0075] The method for adjusting the brightness of a display screen is applied to an electronic device. Specifically, the execution subject of the method for adjusting the brightness of a display screen is one or at least two processors of the electronic device.

[0076] The display screen is composed of at least two light panels, there is a gap between two adjacent light panels, and each light panel includes a plurality of lamp beads.

[0077] like Figure 2 As shown, the method includes:

[0078] Step S201: determining a vertex region, a first point region, and a second point region, wherein the vertex region is a region composed of a plurality of lamp beads at the intersection of the horizontal gap and / or the vertical gap, and the first point region and the second point region are adjacent regions of the vertex region;

[0079] In an embodiment of the present application, a gap correction software is installed in the electronic device, wherein the gap correction software is used to correct the screen of the display device.

[0080] In an embodiment of the present application, the display device includes an LED screen, wherein the LED screen is used to display images in the electronic device. The electronic device includes an LED control system, wherein the LED control system is used to control the LED screen to flash or provide the electronic device with a method for setting parameters of the LED control system.

[0081] In an embodiment of the present application, a screen window that is completely consistent with the resolution of the display screen is drawn in the gap correction software, and the window is displayed on the screen of the display screen at a 1:1 ratio by setting the LED control system parameters. The coordinates of all gaps on the current screen are read through the LED control system in the gap correction software, and the steps of setting the LED control system parameters include: connecting the LED controller and the computer, and ensuring normal communication between them; turning on the LED control system and finding the parameter setting option in the software; setting various parameters of the LED control system according to actual needs; and saving after confirming the settings to make the settings effective.

[0082] Furthermore, when determining the position of the gap, the position of the gap is judged by the human eye, and the position of the gap is highlighted or flashed in the screen window. At the same time, the same position on the display screen will also appear highlighted or flashed. When setting the highlight or flash, the position information is sent to the LED control system in the form of a video signal or by sending the position information to the LED control system. The LED control system controls the screen window to display the highlight or flashing position of the gap, thereby determining the position of the gap.

[0083] In an embodiment of the present application, the position of the gap can also be determined by taking a picture of the display screen with a camera or a mobile phone, such as by photographing the entire display screen or photographing different areas to determine the position of the gap in the photographed picture.

[0084] Specifically, determine the vertex area and select a certain gap intersection point to form a point area. The gap intersection point is also called a vertex. The vertex is the lamp bead at the intersection of the horizontal gap and / or the vertical gap. There are several lamp beads at the intersection of the horizontal gap and / or the vertical gap. The lamp beads at the intersection of the several gaps form a vertex area.

[0085] In an embodiment of the present application, when the vertex area is located between four light panels, the vertex area includes four lamp beads; when the vertex area is located at the edge of the display screen, the vertex area includes two lamp beads; when the vertex area is located at the corner of the display screen, the vertex area includes one lamp bead.

[0086] Specifically, according to the position of the vertex region, two regions adjacent to the vertex region are selected as the first point region and the second point region.

[0087] In an embodiment of the present application, when the vertex area is located between four light panels, at least two columns of lamp beads on the left side of the vertex area are selected to form a first point area, and at least two columns of lamp beads on the right side of the vertex area are selected to form a second point area, wherein each column includes two lamp beads; when the vertex area is located at the left or right edge of the display screen, at least two columns of lamp beads on the left or right side of the vertex area are selected to form the first point area, and the number of lamp beads in the second point area is 0, wherein each column includes two lamp beads; when the vertex area is located at the corner of the display screen, at least two columns of lamp beads on the left or right side of the vertex area are selected to form the first point area, and the number of lamp beads in the second point area is 0, wherein each column includes one lamp bead.

[0088] In an embodiment of the present application, when the vertex area is located between four light panels, at least two rows of lamp beads above the vertex area can be selected to form a first point area, and at least two rows of lamp beads below the vertex area can be selected to form a second point area, wherein each row includes two lamp beads; when the vertex area is located at the upper or lower edge of the display screen, at least two rows of lamp beads above or below the vertex area can be selected to form the first point area, and the number of lamp beads in the second point area is 0, wherein each row includes two lamp beads; when the vertex area is located at the corner of the display screen, at least two rows of lamp beads above or below the vertex area can be selected to form the first point area, and the number of lamp beads in the second point area is 0, wherein each row includes one lamp bead.

[0089] In the embodiment of the present application, the determined vertex area, the first point area, and the second point area are always on a line, for example, the three are on the same horizontal line, or the three are on the same vertical line.

[0090] In the embodiment of the present application, the positions of the vertex area, the first point area, and the second point area are determined to further adjust the brightness of the lamp beads in the vertex area.

[0091] Please refer to Figure 3 , Figure 3 This is an example schematic diagram of a vertex area, a first point area, and a second point area provided in an embodiment of the present application;

[0092] like Figure 3 As shown in the figure, some lamp beads are in one of the horizontal gaps. The four points in area B are four lamp beads at the intersection of four lamp panels, that is, the gap intersection points. The area formed by the four lamp beads is the vertex area, that is, area B is the vertex area; area A is the adjacent area on the left of area B, that is, the first point area; area C is the adjacent area on the right of area B, that is, the second point area.

[0093] In the embodiment of the present application, the example of the positions of the vertex area, the first point area, and the second point area determined above is only one example in the present application, and is only for the convenience of readers' understanding and is not limited here.

[0094] Step S202: Calculate a first average seam trimming coefficient corresponding to the first point area and the second point area, and a second average seam trimming coefficient corresponding to the vertex area;

[0095] Specifically, the first average seam trimming coefficient is the average seam trimming coefficient of the first point area and the second point area before adjustment, and the second average seam trimming coefficient is the average seam trimming coefficient of the vertex area before adjustment, wherein the first average seam trimming coefficient is one of the key parameters when compared with the second average seam trimming coefficient later. The specific method for calculating the first average seam trimming coefficient and the second average seam trimming coefficient is as follows.

[0096] Please refer to Figure 4 , Figure 4 yes Figure 2 A detailed flow chart of step S202 in FIG.

[0097] like Figure 4 As shown, step S202 includes:

[0098] Step S2021: Calculate the sum of the first trimming coefficients of all lamp beads in the first point area and the second point area, and obtain a first average trimming coefficient through the sum of the first trimming coefficients and the total number of lamp beads in the first point area and the second point area;

[0099] In the embodiment of the present application, taking the vertex area being located between four light panels as an example, the sum of the first trimming coefficients of the first point area and the second point area and the first average trimming coefficient are calculated.

[0100] Specifically, at least two rows of lamp beads are selected above the vertex area to form a first point area, and at least two rows of lamp beads are selected below the vertex area to form a second point area. Further, when calculating the sum of the first trimming coefficients of all lamp beads in the first point area and the second point area, select one row of lamp beads in the first point area and the two adjacent left and right lamp beads in the row, and calculate the trimming coefficient of the column of lamp beads. Since the first point area and the second point area are always on the same line, the trimming coefficients of the first point area and the second point area are the same, and it is only necessary to calculate the trimming coefficient of the lamp beads in one of the areas, where the trimming coefficient is the first trimming coefficient. The specific method for calculating the trimming coefficient is as shown in the following example.

[0101] Please refer to Figure 5 , Figure 5 This is an example schematic diagram of calculating a seam repair coefficient provided in an embodiment of the present application;

[0102] like Figure 5 As shown, A, B, C, and D are lamp beads, and lamp beads B and C are a row of lamp beads in the first point area. Lamp beads B and C are located between two adjacent light boards. Lamp beads A and B are on one light board, and lamp beads C and D are on another light board. Assume that the interval between two lamp beads inside the light board is 1.0, the interval between B and C is 0.8, and the original luminous brightness of a single lamp bead is 100.

[0103] In the embodiment of the present application, under ideal conditions, the spacing between the four lamp points A, B, C, and D is 1.0, and the luminous brightness of all lamp points between A, B, C, and D is 100. Then, the sum of the luminous brightness of all lamp beads from the center point of A to the center point of D is 100 / 2+100+100+100 / 2=300. Further calculation shows that the luminous brightness per unit distance is 300 / 3.0=100, wherein the lamp beads emit light 360 degrees around on the plane, and the luminous brightness of 360 degrees on the plane is consistent. Then 100 / 2 is half the luminous brightness of a certain lamp bead, that is, 100 / 2 is half the luminous brightness of lamp bead A or half the luminous brightness of lamp bead D. It can be understood that only the luminous brightness of the right half of lamp bead A will affect the total brightness between lamp beads A and B. The current interval between B and C is 0.8. Assume that the gap correction coefficient between B and C is x. In order to adjust the brightness between B and C so that the total brightness of the four points remains unchanged, according to the calculation method under ideal conditions, we can get: (100 / 2+(100+100)*x+100 / 2))=100. Finally, the gap correction coefficient x between B and C is calculated to be 0.9.

[0104] In the embodiment of the present application, the lamp boards are parallel to each other, that is, the calculated seam trimming coefficient of B and C is 0.9, and the seam trimming coefficient of other lamp beads parallel to B and C is also 0.9. B and C are located in the first point area, and the first seam trimming coefficient of all lamp beads in the first point area is 0.9. Since the first seam trimming coefficients of the first point area and the second point area are the same, the first seam trimming coefficients of all lamp beads in the second point area are 0.9.

[0105] In the embodiment of the present application, the above example of calculating the seam repair coefficient is only one example. At the same time, the method of calculating the seam repair coefficient is also applicable to calculating the seam repair coefficient of other areas, which will not be repeated here.

[0106] Specifically, the first trimming coefficient of all the lamp beads in the first point area and the second point area is calculated according to the method for calculating the trimming coefficient of the present application, and then the total number of lamp beads in the first point area and the second point area is determined, and the sum of the first trimming coefficients of all the lamp beads in the first point area and the second point area is further obtained, and the first average trimming coefficient is obtained by dividing the sum of the first trimming coefficients by the total number of lamp beads. For example, when the vertex area is located between four lamp panels, the number of lamp beads in the selected first point area and the second point area is 6, and the first trimming coefficient of each lamp bead in the first point area and the second point area is 0.9, the total number of lamp beads in the first point area and the second point area is 12, and the sum of the first trimming coefficients is 0.9*12. According to the formula first average trimming coefficient = sum of first trimming coefficients / total number of lamp beads, the first average trimming coefficient = 0.9*12 / 12 = 0.9 is obtained.

[0107] In an embodiment of the present application, a calculation method for calculating the seam trimming coefficient is given, and then the first seam trimming coefficient corresponding to the first point area and the second point area is further calculated. Finally, the first seam trimming coefficient is divided by the total number of lamp beads in the first point area and the second point area to obtain the first average seam trimming coefficient corresponding to the first point area and the second point area. The calculation method given is simple and easy to understand.

[0108] Step S2022: Calculate the sum of the second trimming coefficients of all lamp beads in the vertex area, and obtain a second average trimming coefficient by the sum of the second trimming coefficients and the total number of lamp beads in the vertex area;

[0109] Specifically, first calculate the second trimming coefficient of the lamp beads in the vertex area, determine the total number of lamp beads in the vertex area, then obtain the sum of the second trimming coefficients of all lamp beads in the vertex area, and finally divide the sum of the second trimming coefficients by the total number of lamp beads in the vertex area to obtain the second average trimming coefficient.

[0110] In the embodiment of the present application, when the vertex area is located between four light boards, there are two ways to calculate the seam trimming coefficient of the lamp beads in the vertex area; when the vertex area is located at other positions, the way to calculate the second seam trimming coefficient of the lamp beads in the vertex area is the same as the way to calculate the first seam trimming coefficient of the lamp beads in the first point area and the second point area, and no further examples are given here. The specific way to calculate the second seam trimming coefficient of the lamp beads in the vertex area between the four light boards is as follows.

[0111] Please refer to Figure 6 , Figure 6 This is an example schematic diagram of calculating the seam repair coefficient of the vertex area lamp beads provided in an embodiment of the present application;

[0112] like Figure 6 As shown, the four areas divided by the cross lines are parts of the four light boards, the four black dots (intersection points of the gaps, also vertices) are the lamp beads at the intersection of the four light boards, and the gray dots are the lamp beads adjacent to each other in pairs of light boards.

[0113] In the embodiment of the present application, it is assumed that the spacing between the lamp beads inside the lamp board is 1.0, the current spacing between the lamp boards is 0.8, and when the luminous brightness of each lamp bead is 100, first calculate only the vertical gap, and calculate the vertical gap trimming coefficient according to the above method of calculating the first trimming coefficient. The vertical gap trimming coefficient is calculated to be 0.9. Similarly, the horizontal gap trimming coefficient is also calculated to be 0.9. The trimming coefficient at the vertex is 0.9*0.9=0.81, that is, the second trimming coefficient at the vertex is 0.81.

[0116] In the embodiment of the present application, it is assumed that the spacing between the lamp beads inside the lamp board is 1.0, the current spacing between the lamp boards is 0.8, the second trimming coefficient of the vertex lamp bead is x, the luminous intensity of a single lamp bead is 1.0, and the trimming coefficient of the gray lamp bead is 0.9. The luminous intensity of the adjusted gray lamp bead is 0.9. Ignoring the size of the lamp beads, the total area of ​​the region is (1.0+1.0+0.8)*(1.0+1.0+0.8)=2.8*2.8, and the total luminous intensity is 4*(1.0 / 4)+8*(0.9 / 2)+4*x=1+1.36+4*x, then (1+1.36+4*x) / (2.8*2.8)=(4*(1.0 / 4)+8*1.0 / 2+4*1.0) / 3*3=1, and x=0.81 is obtained. 4*(1.0 / 4) is the luminous intensity of the four corner lamps after adjustment.

The second average trimming coefficient is obtained by dividing the sum of the second trimming coefficients by the total number of lamp beads in the vertex area.

[0119] In an embodiment of the present application, three methods of calculating the seam trimming coefficients of the lamp beads in the vertex area are provided. A second seam trimming coefficient can be obtained based on the seam trimming coefficients of the lamp beads in the vertex area, and a second average seam trimming coefficient corresponding to the vertex area can be further obtained.
