[0041] Example 1

[0042] Figure 1 This is a flow chart of a display mode determination method provided by the first embodiment of the present invention. This embodiment is applicable to the case of calibrating a display module to be calibrated constituting a target display screen. The method can be executed by a display mode determination device, which can be implemented in the form of hardware and / or software. The display mode determination device can be configured in electronic devices such as mobile phones, computers or servers. Figure 1 As shown, the method includes:

[0043] S110 . Upon receiving a display screen calibration request, obtain at least one display module to be calibrated constituting a target display screen.

[0044] The display calibration request may be a received request to calibrate the target display. Alternatively, the display calibration request may be a request issued by a corresponding user triggering a corresponding control, or may be a display calibration request generated based on actual calibration requirements.

[0045] The target display screen may be composed of at least one display module to be calibrated. The target display screen may be composed of multiple light-emitting diodes (LEDs). The display module to be calibrated may be the smallest functional unit constituting the target display screen. Optionally, the display module to be calibrated may include components such as LED lamp beads, a driver circuit, a circuit board, a heat dissipation structure, and a housing.

[0046] Specifically, when a display screen calibration request is received, at least one display module to be calibrated constituting a target display screen is acquired, so as to perform display calibration processing on the at least one display module to be calibrated.

[0047] S120 . For at least one display module to be calibrated, when curvature information of the display module to be calibrated meets a preset condition, determine an initial real point position map corresponding to the display module to be calibrated.

[0048] The real points in the initial real point position diagram correspond to light-emitting diodes in the display module to be calibrated.

[0049] The preset condition may be a pre-set condition that the curvature information must satisfy. Optionally, when the curvature information of the display module to be calibrated exceeds a preset curvature threshold, it is determined that the curvature information of the display module to be calibrated satisfies the preset condition. The preset curvature threshold may be a pre-set standard value of curvature information corresponding to the module edge of the display module to be calibrated.

[0050] It should be noted that the subsequent processing in the embodiments of the present invention primarily targets display modules to be calibrated whose curvature information exceeds a preset curvature threshold. For example, calibration processing is performed on sector-shaped display modules and / or circular display modules. The initial real point position map may include solid points and empty points, where solid points correspond to light-emitting diodes (LEDs) in the display module to be calibrated. Empty points correspond to missing components, reserved locations, and / or unconnected areas in the display module to be calibrated.

[0051] Specifically, for at least one display module to be calibrated, when curvature information of the display module to be calibrated exceeds a preset curvature threshold, it is determined that the display module to be calibrated meets the preset condition. If it is determined that the display module to be calibrated meets the preset condition, the display module to be calibrated is tested to obtain an initial real point schematic diagram corresponding to the display module to be calibrated.

[0052] In an embodiment of the present invention, a method for determining an initial real point position diagram corresponding to the display module to be calibrated may be: when the curvature information of the display module to be calibrated exceeds a preset curvature threshold, performing a light-on and light-off instruction test on the display module to be calibrated to obtain a test result; wherein the test result is used to characterize the light-on and light-off state of the light-emitting diode corresponding to the display module to be calibrated; based on the test result, determining the initial real point position diagram corresponding to the display module to be calibrated.

[0053] The on / off command test process is used to send an on / off command to each LED in the display module to be calibrated to determine which LEDs in the display module are capable of emitting light. The test result is used to indicate the on / off status of the corresponding LED in the display module to be calibrated under the corresponding on / off command.

[0054] Specifically, when the curvature information of the display module to be calibrated meets a preset curvature threshold, a light-on / off command test is performed on the display module to determine the light-on / off state of the light-emitting diodes in the display module under the light-on / off command, thereby obtaining a test result. Based on the test result, an initial real point position map corresponding to the display module to be calibrated is determined.

[0055] For example, the display module to be calibrated is as follows Figure 2 Taking the fan-shaped display module J1 as an example, if the curvature information of the fan-shaped display module J1 exceeds the preset curvature threshold, the fan-shaped display module J1 is subjected to a light-off instruction test process to obtain the following information: Figure 3 The initial real point positions of the sector display module J1 are shown. It should be noted that the sector display module J1 performs the most basic point mapping table, deleting invalid areas without LED mapping. Because each row of the sector display module has a curvature, the image will be curved, and the presence of empty points between the real points will cause the image to be discontinuous. Therefore, the technical solution described in the embodiments of the present invention can be used to calibrate the sector display module.

[0056] S130 , performing initial position adjustment processing on the real points in the initial real point position map to obtain a first real point position map.

[0057] The initial position adjustment process may include rearranging the real points in the initial real point position map so that the adjacent points of the real points within a preset range are real points. The preset range may be a pre-set range of pixels in the real point position map. Optionally, the preset range may be determined based on the number and size of the real points in the initial real point position map. The first real point position map may be a real point position map obtained after position adjustment of the real points in the initial real point position map.

[0058] Specifically, the real points in the initial real point position map are rearranged so that points adjacent to the real points within a preset range are real points, thereby obtaining a first real point position map.

[0059] In an embodiment of the present invention, the method for determining the first real point position map can be: traversing each pixel point in the initial real point position map to determine that the pixel point is a real point when it is detected that the pixel value information of the pixel point meets the preset pixel range; if it is detected that the pixel value information of the pixel point does not meet the preset pixel range, the pixel point is determined to be an empty point; and rearranging at least one real point to obtain the first real point position map when the real point and the pixel points adjacent to the real point within the preset range are real points.

[0060] The pixel value information may be the pixel value information of the pixel point in the initial real point position map, and the preset pixel range may be a pre-set pixel value range corresponding to the real point.

[0061] Specifically, a traversal process is performed on each pixel in the initial real point location map. When it is detected that the pixel value information of the pixel point falls within a preset pixel range, the pixel point is determined to be a real point. If it is detected that the pixel value information of the pixel point does not satisfy the preset pixel range, the pixel point is determined to be a null point. At least one real point is rearranged so that the real point and the pixel points adjacent to the real point within the preset range are real points, thereby obtaining a first real point location map.

[0062] It should be noted that if the real point in the initial real point position map includes multiple pixel points, it is necessary to determine that when the pixel value information of the multiple pixel points all meet the preset pixel range, the point corresponding to the multiple pixel points is determined to be the real point.

[0063] Optionally, the rearrangement of at least one real point may be: constructing a box-based function to adjust the positions of the real points in the initial real point position map to obtain a first real point position map. Figure 4As shown, the initial real point position diagram is processed to eliminate gaps in the horizontal and vertical directions, that is, the real points of the initial real point position diagram are aligned to the left and aligned downwards to obtain Figure 4 Correspondingly, the display effect of the display module to be calibrated corresponding to the first real point position diagram after the real points are rearranged is as follows: Figure 5 shown.

[0064] S140 : Determine a second real point position map according to a first real point position map of at least one display module to be calibrated and preset module arrangement sequence information.

[0065] The preset module arrangement sequence information may be a preset module arrangement sequence corresponding to at least one display module to be calibrated. The second real point position map may be a preset real point position map obtained by arranging at least one real point position map according to the preset module arrangement sequence.

[0066] Specifically, at least one first real point position map is arranged according to preset module arrangement sequence information of at least one display module to be calibrated to obtain a second real point position map.

[0067] For example, see Figure 6 If the target display screen includes one display module to be calibrated, and the curvature information of the display module to be calibrated meets the preset conditions, then the first real point position map of the display module to be calibrated is the second real point position map. If the target display screen includes multiple display modules to be calibrated, and the curvature information of each display module to be calibrated meets the preset conditions, then the multiple first real point position maps corresponding to the multiple display modules to be calibrated can be calculated according to Figure 6 Arrange the data in the manner shown to obtain Figure 6 The second solid point position diagram is shown.

[0068] S150 , performing display position calibration processing on each real point in the second real point position map according to the position calibration function to obtain target display position information corresponding to each real point, so as to control the target display screen to display the target display image based on the target display position information.

[0069] The position calibration function can be used to determine the target display position information for each real point in the second real point position map. The target display position information can be the final display position corresponding to each real point in a preset coordinate system. The target display position information can be represented by horizontal and vertical coordinate information in the preset coordinate system. The preset coordinate system can be a coordinate system set according to actual needs. The target display image can be an image transmitted by an upper-level system after the target display position information is determined, for display on the target display screen.

[0070] Specifically, display position calibration processing is performed on each real point in the second real point position map according to the position calibration function to obtain the target display position information corresponding to each real point, so that after receiving the target display image, the target display screen is controlled to display the target display image according to the target display position information of each real point.

[0071] The technical solution of this embodiment is to obtain at least one display module to be calibrated constituting a target display screen upon receiving a display screen calibration request. For at least one display module to be calibrated, when the curvature information of the display module to be calibrated meets a preset condition, an initial real point position map corresponding to the display module to be calibrated is determined to provide image support for the subsequent calibration of the display module to be calibrated. The real points in the initial real point position map are subjected to initial position adjustment processing to obtain a first real point position map. Based on the first real point position map of at least one display module to be calibrated and the preset module arrangement order information, a second real point position map is determined. Display position calibration processing is performed on each real point in the second real point position map according to the position calibration function to obtain the target display position information corresponding to each real point, so as to control the target display screen to display the received target display image based on the target display position information. The present invention solves the problems of low efficiency, poor calibration accuracy and high labor cost in the manual calibration of display modules in the prior art, realizes rapid calibration processing of at least one display module to be calibrated, improves calibration accuracy, and ensures the display effect of the target display screen.

[0072] Example 2

[0073] Figure 7 This is a flow chart of a display mode determination method provided by the second embodiment of the present invention. This embodiment is a preferred embodiment of the above embodiment. Its specific implementation method can refer to the technical solution of this embodiment. Among them, the technical terms that are the same or corresponding to the above embodiment are not repeated here. Figure 7 As shown, the method includes:

[0074] S210 . Upon receiving a display screen calibration request, obtain at least one display module to be calibrated constituting a target display screen.

[0075] S220 . For at least one display module to be calibrated, when curvature information of the display module to be calibrated meets a preset condition, determine an initial real point position map corresponding to the display module to be calibrated.

[0076] The real points in the initial real point position diagram correspond to light-emitting diodes in the display module to be calibrated.

[0077] S230 , performing initial position adjustment processing on the real points in the initial real point position map to obtain a first real point position map.

[0078] S240 , arranging at least one first real point position map according to preset module arrangement sequence information corresponding to at least one display module to be calibrated, to determine a second real point position map.

[0079] Specifically, at least one first real point position map is arranged according to preset module sequence information corresponding to at least one display module to be calibrated to obtain a second real point position map.

[0080] S250: Determine target angle information of the target display screen.

[0081] The target angle information may be the angle information corresponding to the target display screen. For example, if the target display screen is a circular display screen, the target angle information is 360 degrees; if the target display screen is a semicircular display screen, the corresponding target angle information is 180 degrees. Accordingly, if the target display screen is a display screen composed of a sector-shaped display module, the corresponding target angle information is the angle of the sector-shaped display module.

[0082] Specifically, target angle information of the target display screen is determined, so as to determine target display position information of each real point through the target angle information and a position calibration function.

[0083] S260 , determining the real point sequence information, the real point interval angle, and the real point distance information corresponding to each real point in the second real point position map based on the target angle information and the real point quantity information in each row of the second real point position map.

[0084] Among them, the real point sequence information is used to characterize the order of the real points in the row to which they belong. In other words, the real point sequence information can be used to determine the row to which the real point belongs, and the number of the real points in the order from left to right. The real point interval angle information is the interval angle between the real point and the adjacent real point. Optionally, the real point interval angle information is obtained based on the ratio between the target angle information and the real point quantity information of the row to which the real point belongs. The real point quantity information can be used to characterize the number of real points in the row to which the current real point belongs. For example, if the target angle information is 180 degrees and the number of real points in the row to which the real point belongs is 18, then the real point interval angle can be 10 degrees. The real point distance information is the distance information between the row to which the real point belongs and the row to which the target real point belongs. The target real point can be the real point corresponding to the center of the target display screen in the second real point position map. For example, the target real point can be the real point in the upper left corner of the second real point position map.

[0085] Specifically, the real point spacing angle corresponding to each real point is determined based on the ratio between the target angle information and the number of real points in each row of the second real point location map. Furthermore, the real point sequence information corresponding to each real point in the second real point location map is determined. The distance between the row to which each real point belongs and the row to which the target real point belongs in the second real point location map is used as the real point distance information for each real point.

[0086] S270 , substituting the real point interval angle, real point sequence information, and real point distance information corresponding to each real point into a position calibration function to obtain target display position information of each real point.

[0087] Among them, the position calibration function can be expressed as:

[0088] y=sin(θ 当前行点间隔角度 )*N 第几个点 *R′ 当前行到圆心的半径

[0089] x=cos(θ 当前行点间隔角度 )*N 第几个点 *R′ 当前行到圆心的半径

[0090] Among them, θ 当前行点间隔角度 Indicates the real point interval angle, N 第几个点 Represents the real point order information, R′ 当前行到圆心的半径 Indicates the distance information of the actual point. x indicates the horizontal coordinate of the actual point in the target display position information. y indicates the vertical coordinate of the actual point in the target display position information.

[0091] Specifically, the real point interval angle, real point sequence information and real point distance information corresponding to each real point are substituted into the position calibration function to obtain the horizontal and vertical coordinates of each real point in the preset coordinate system, that is, the target display position information of each real point is obtained.

[0092] Exemplarily, if the target display screen is a fan-shaped display screen composed of a fan-shaped display module J1, then according to the second real point position diagram corresponding to the fan-shaped display module J1, the upper left corner of the second real point position diagram is used as the center of the circle, the last row of real points is used as the circumference, and the distance between the last row of real points and the first row of real points is used as the radius. Scan downward from the center of the circle, and determine the real point interval angle of each row of real points according to the number of real points in each row and the target angle information of the fan-shaped display screen. And determine the real point sequence information and real point distance information of each row of real points. Substitute the real point interval angle, real point sequence information and real point distance information corresponding to each real point into the position calibration function to obtain the target display position information of each real point, so as to calibrate the second real point position diagram based on the target display position information of each real point, and obtain the calibrated real point position diagram, such as Figure 8 The example of the target display screen display effect corresponding to the calibrated real point position diagram is shown in the figure below. Figure 9 shown.

[0093] Correspondingly, if the target display screen is a circular display screen composed of at least one sector-shaped display module, the target display position information of each real point can be determined by the above method, so as to calibrate the second real point position map based on the target display position information of each real point to obtain the calibrated real point position map, such as Figure 10 shown.

[0094] S280: Send the target display position information of each real point to the target FPGA control card, so that when the target FPGA control card receives the target display image, it controls the target display screen to display the target display image according to the target display position information.

[0095] The target display programmable gate array control card may be a display programmable gate array (FPGA) control card for receiving target display information of each real point. The target display image may be an image to be displayed on a target display screen.

[0096] Specifically, the target display position information of each actual point is sent to the target FPGA control card, so that when the target FPGA control card receives the target display image, the target display screen performs the lamp bead display calibration processing according to the target display position information and displays the target display image. For example, the display effect diagram of the target display screen displaying the target display image can be as follows: Figure 11 shown.

[0097] The technical solution of this embodiment is to obtain at least one display module to be calibrated constituting the target display screen when a display screen calibration request is received. For at least one display module to be calibrated, when the curvature information of the display module to be calibrated meets the preset conditions, determine the initial real point position map corresponding to the display module to be calibrated to provide image support for the subsequent calibration of the display module to be calibrated. Perform initial position adjustment processing on the real points in the initial real point position map to obtain a first real point position map. According to the preset module arrangement order information corresponding to at least one display module to be calibrated, arrange the at least one first real point position map to determine the second real point position map. Determine the target angle information of the target display screen and determine the real point sequence information, real point interval angle and real point distance information corresponding to each real point in the second real point position map based on the target angle information and the number of real points in each row in the second real point position map. Substitute the real point interval angle, real point sequence information and real point distance information corresponding to each real point into the position calibration function to obtain the target display position information of each real point. The target display position information of each actual point is sent to the target field programmable gate array control card, so that when the target field programmable gate array control card receives the target display image, the target display screen is controlled to display the target display image according to the target display position information. The present invention solves the problems of low efficiency, poor calibration accuracy and large labor costs in the manual calibration of display modules in the prior art, realizes the rapid calibration processing of at least one display module to be calibrated, improves the calibration accuracy, reduces labor costs, ensures the display effect of the target display screen, and improves user satisfaction. In addition, the technical solution provided by the embodiment of the present invention can support multiple platforms such as PC, Android and web front-end to determine the target display position information, thereby improving the flexibility and applicability of determining the target display position information.

[0099] Figure 12 This is a schematic diagram of the structure of a display mode determination device provided by the third embodiment of the present invention. Figure 12 As shown, the device includes: a display module acquisition module 310 , an initial real point position map determination module 320 , an initial position adjustment module 330 , a position map arrangement module 340 and an image display module 350 .
