Description

Technical Field

[0001] The present application relates to the field of LED display screens, and in particular to an LED display screen seam processing method, an LED display screen assembly method, an LED display screen, an electronic device, and a storage medium. Background Art

[0002] The LED display screen is composed of several LED cabinets, which are in turn composed of several LED display unit boards. The display unit boards have pixels set at a fixed standard value for spacing. However, due to processing and assembly tolerances, a seam that is too large or too small is formed at the joint of two adjacent display unit boards, making it impossible for the distance between the edge pixels to be completely consistent with the internal standard value. When the seam is too wide, the edge pixel spacing is too large compared to the standard value. When visually viewing, the edge area is perceived to be darker than other places, and a sensory dark seam appears. When the edge pixel spacing is too small compared to the standard value, the edge area is perceived to be brighter than other places, and a sensory bright seam appears. With the popularization of LED display applications, the product point spacing continues to decrease, and the display effect requirements for the entire screen after the display is spliced ​​and lit are getting higher and higher. In order to improve the display effect, it is necessary to ensure that there is no bright or dark seam on the entire screen. Therefore, how to solve the bright and dark seams of the display screen has become an urgent problem to be solved.

[0003] In the related art, LED display unit panels whose edge pixel points partially exceed the outer contour of the LED display unit panels are spliced ​​to solve the seam problem at the joints of the LED display unit panels. However, due to processing errors in the size of the LED display unit panels and the size of the LED cabinet, there is still a physical difference between the edge pixel spacing and the preset standard pixel spacing, resulting in dark seams.

[0004] Currently, no effective solution has been proposed to solve the problem of dark seams caused by physical differences between edge pixel pitch and preset standard pixel pitch due to processing errors in the size of LED display unit panels and LED cabinets. Summary of the invention

[0047] In one embodiment of the present application, a method for processing a seam of an LED display screen is provided. Figure 2 : is a flow chart of a method for processing a seam of an LED display screen according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0048] Step S201, obtaining preset dimensions and processing error ranges of the LED display unit board and the LED box, and obtaining matching parameters between the LED display unit board and the LED box according to the preset dimensions of the LED display unit board and the LED box.

[0049] In this embodiment, the matching parameters between the LED display unit board and the LED box are obtained according to the preset sizes of the LED display unit board and the LED box, including but not limited to the following methods:

[0050] The lateral mutual matching parameters are obtained according to the maximum number of LED display unit boards that can be accommodated in the LED box along the horizontal direction; the longitudinal mutual matching parameters are obtained according to the maximum number of LED display unit boards that can be accommodated in the LED box along the vertical direction; and the mutual matching parameters are obtained according to the lateral mutual matching parameters and the longitudinal mutual matching parameters.

[0051] To clearly understand the above method of obtaining interworking parameters, Figure 3 The structure diagram of an LED display screen according to an embodiment of the present application is shown in the figure. The LED display screen has an LED box 1, and there are four LED display unit boards 2 in the LED box 2. The LED display unit boards 2 are provided with pixel points 3. Figure 4 FIG. 1 is a schematic diagram of an LED box and an LED display unit board according to an embodiment of the present application. Figure 4 In the figure, the LED box body length dimension is the dimension of the LED box body in the horizontal direction; the LED box body width dimension is the dimension of the LED box body in the vertical direction; the LED display unit board length dimension is the dimension of the LED display unit board in the horizontal direction; the LED display unit board width dimension is the dimension of the LED display unit board in the vertical direction. Assume that the preset size of the LED box body is 600*400mm, that is, the preset size of the LED box body in the horizontal direction is 600mm, and the preset size in the vertical direction is 400mm, and the preset size of the LED display unit board 2 is 300*200mm, that is, the preset size of the LED display unit board in the horizontal direction is 300mm, and the preset size in the vertical direction is 200mm. In the horizontal direction, an LED box body can accommodate at most two LED display unit boards, and the horizontal mutual matching parameter is 2. In the vertical direction, an LED box body can accommodate at most two LED display unit boards, and the longitudinal mutual matching parameter is 2. Thus, the mutual matching parameter of the LED display unit board and the LED box body is 2*2.

[0052] Step S202, obtaining a joint distance of spliced ​​LED display unit boards according to preset sizes, processing error ranges, and matching parameters of the LED display unit boards and the LED box.

[0053] Step S203, determining the adjustment dimensions of the LED display unit board and the LED box according to the matching parameters and the joint distance, and obtaining the actual processing dimensions of the LED display unit board and the LED box according to the adjustment dimensions.

[0054] The actual processing dimensions obtained by adjusting the dimensions of the LED display unit board and the LED box body through the adjusted dimensions obtained in the above steps can, on the one hand, ensure that even if there are processing errors in the actual processing process, no dark seams will appear on the LED display screen under close observation; on the other hand, using the adjusted dimensions to process the LED display unit board and the LED box body can directly avoid dark seams, and no further operation is required after assembly is completed, which brings convenience to users.

[0055] In some of the embodiments, according to the preset size, processing error range and matching parameters of the LED display unit board and the LED box, obtaining the seam distance of the spliced ​​LED display unit board includes:

[0056] The minimum size of the LED display unit board is determined according to the preset size and processing error range of the LED display unit board, and the maximum size of the LED box is determined according to the preset size and processing error range of the LED box; the joint distance is obtained according to the minimum size of the LED display unit board, the maximum size of the LED box and the matching parameters.

[0057] Assuming that the preset size of the LED cabinet is 600*400mm, the processing error is: +0 / -0.15mm, the preset size of the LED display unit board is 300*200mm, and the processing error is: +0 / -0.1mm, then the minimum size of the LED display unit board is 299.9*199.9mm, the maximum size of the LED cabinet is 600*400mm, and the matching parameter is 2*2.

[0058] This embodiment adopts the extreme value method to obtain the joint distance. Taking the horizontal direction as an example, the joint distance obtained in the horizontal direction is: the maximum size of the LED box - (the minimum size of the LED display unit board * the horizontal matching parameter), that is, 600-299.9*2=0.2mm.

[0059] In some of the embodiments, according to the preset size, processing error range and matching parameters of the LED display unit board and the LED box, obtaining the seam distance of the spliced ​​LED display unit board includes:

[0060] The average size of the LED display unit board is determined according to the preset size and processing error range of the LED display unit board, and the average size of the LED box is determined according to the preset size and processing error range of the LED box; the joint distance is obtained according to the average size of the LED display unit board, the average size of the LED box and the matching parameters.

[0061] Assuming that the preset size of the LED cabinet is 600*400mm, the processing error is: +0 / -0.15mm, the preset size of the LED display unit board is 300*200mm, and the processing error is: +0 / -0.1mm, then the average size of the LED display unit board is 299.95*199.95mm, the average size of the LED cabinet is 599.925*399.925mm, and the matching parameter is 2*2.

[0062] This embodiment adopts the root mean square method to obtain the joint distance. Taking the horizontal direction as an example, the nominal value of the joint distance is: the average size of the LED box - (the average size of the LED display unit board * the horizontal matching parameter), that is, 599.925-(299.95*2) = 0.025mm; the square of the nominal tolerance of the joint distance is: the square of the average error of the LED box + the horizontal matching parameter * the square of the average error of the LED display unit board, and the nominal tolerance is The joint distance is: (nominal value of the joint distance + nominal tolerance of the joint distance) / transverse matching parameter, that is, (0.025 + 0.103) / 2 = 0.064 mm.

[0063] In some embodiments, determining the adjustment size of the LED display unit board and the LED box according to the matching parameters and the joint distance includes:

[0064] The shrinking size of the LED display unit board is determined according to the joint distance, and the adjustment size of each frame of the LED display unit board relative to the center point of the LED display unit board is determined according to the shrinking size of the LED display unit board; the shrinking size of the LED box is determined according to the matching parameters and the joint distance, and the adjustment size of each frame of the LED box relative to the center point of the LED box is determined according to the shrinking size of the LED box.

[0065] In this embodiment, the mutual matching parameter * the shrinkage size of the LED display unit board = the joint distance. Assuming that the joint distance is 0.2mm and the shrinkage size of the LED display unit board is 0.1mm, it is equivalent to the side frames on both sides of the LED display unit board parallel to the joint shrinking by 0.05mm relative to the center point of the LED display unit board. The shrinkage size of the LED box is the joint distance of 0.2mm, which is equivalent to the side frames on both sides of the LED box parallel to the joint shrinking by 0.1mm relative to the center point of the LED box.

[0066] In some embodiments, before obtaining the actual processing dimensions of the LED display unit board and the LED box according to the adjusted dimensions, the method further comprises:

[0067] According to a preset LED lamp bead size and a preset standard pixel pitch, a coverage size of LED lamp beads arranged on the LED unit board is obtained, wherein the LED lamp beads on the LED display unit board are arranged according to the preset standard pixel pitch; it is determined whether the size of the LED display unit board after the size adjustment process is not less than the coverage size; if it is determined that the size of the LED display unit board after the size adjustment process is less than the coverage size, the matching parameters are readjusted until the size of the LED display unit board after the size adjustment process is not less than the coverage size.

[0068] like Figure 5 The figure is a schematic diagram of the pixel points in the LED display unit board of an embodiment of the present application. The figure shows the arrangement of the pixel points after the LED display unit board is magnified 10 times. The edge pixel points 4 are located on both sides of the joint 7 of two adjacent LED display unit boards. The distance between the edge pixel points 4 on both sides of the joint 7 is the edge pixel point spacing 6. The pixel point size is the size of the LED lamp bead. When the LED display unit board is resized, the LED lamp bead body at the edge cannot be guaranteed to be completely in the LED display unit board. It can be divided into the following situations:

[0069] The first case is that the overall length dimension of the LED display unit board is < (the number of LED lamp beads in the horizontal direction - 1) * the preset standard pixel pitch 5 + the overall length dimension of the pixel.

[0070] The second situation is that the outer width dimension of the LED display unit board is < (the number of LED lamp beads in the vertical direction - 1) * the preset standard pixel pitch 5 + the outer width dimension of the pixel.

[0071] The third situation is that the first and second situations occur at the same time.

[0072] When the first case occurs, the horizontal matching parameter is reduced by 1 and the joint distance is recalculated; when the second case occurs, the vertical matching parameter is reduced by 1 and the joint distance is recalculated; when the third case occurs, the horizontal matching parameter and the vertical matching parameter are reduced by 1 at the same time and the joint distance is recalculated. When the matching parameters are adjusted by the above method until the LED lamp beads can be completely inside the LED display unit board, the size of the LED display unit board and the LED cabinet after the size adjustment is determined to be the actual processing size.

[0073] The above method can ensure that the LED lamp beads are completely within the outline of the LED display unit board, so that the product processed using the LED display unit board size determined by this method can avoid the situation where pixels are damaged due to bumps during transportation.

[0074] It should be noted that in order to ensure the welding strength of the LED lamp beads during the actual processing, a certain edge area should be reserved between the edge of the LED lamp bead pad on the edge of the LED display unit board and the edge of the board. The size of this area is determined according to the performance of the machine.

[0075] In one embodiment of the present application, a LED display assembly method is also provided. After executing the above-mentioned LED display seam processing method to obtain the actual processing dimensions of the LED display unit board and the LED box, the LED display unit board and the LED box are processed according to the actual processing dimensions and assembled to obtain the LED display.

[0076] In some of the embodiments, after processing the LED display unit board and the LED box according to the actual processing size and assembling them to obtain the LED display screen, the method further includes:

[0077] The LED display unit board and the LED cabinet are adjusted by using a preset seam adjuster so that the edge pixel pitch smaller than the preset standard pixel pitch is increased to be equal to the preset standard pixel pitch.

[0078] like Figure 6 This is a schematic diagram of using a preset seam adjuster to adjust the seam according to an embodiment of the present application. After the LED display screen is assembled, the screen is lit, and the preset seam adjuster is used to control and correct the edge pixel spacing at the bright seam of the LED display screen to make it equal to the preset standard pixel spacing, so as to achieve the effect of no bright or dark seams when viewed at any distance.

[0079] In one embodiment of the present application, there is also provided an LED display screen, comprising an LED display unit board and an LED box, wherein the LED display screen is assembled from the LED display unit board and the LED box according to the above-mentioned LED display screen assembly method.

[0082] Optionally, the electronic device may further include a transmission device and an input / output device, wherein the transmission device is connected to the processor, and the input / output device is connected to the processor.
