Description

Technical Field

[0001] The present invention belongs to the technical field of LED display, and in particular relates to a method, device and system for arranging four-in-one lamp beads on an LED display screen. Background Art

[0002] The four-in-one lamp beads in LED display screens are a common product in the current LED market. They save space, have stable performance, and are firmly welded, making them suitable for making high-density products. However, they have a fixed appearance and are relatively large in size as a single point. Currently, the common spherical LED display screens generally do not use four-in-one lamp beads. Because of the appearance characteristics of the four-in-one lamp beads, a series of problems arise when they are used on spherical LED display screens. For example: the edge jagged phenomenon of the unit module is serious, the distribution of the lamp beads is regularly uneven, the lamp beads cannot be placed in a narrow position, or the appearance is not coordinated after the lamp beads are forcibly placed, etc.

[0003] In order to avoid the above-mentioned problems, the spherical LED display uses four-in-one lamp beads, which requires strict control of the shape of the unit module, which is approximately rectangular or trapezoidal, thus limiting the range of use of the four-in-one lamp beads. In addition, the current lamp bead arrangement method results in poor product appearance and display effects, especially the jagged problem on the edge of the unit module. Summary of the invention

[0004] The purpose of the present invention is to provide a method, device and system for arranging four-in-one lamp beads on an LED display screen to solve the problems of poor display effect and jagged edges of unit modules after the four-in-one lamp beads are used on a spherical LED display screen.

[0005] In a first aspect, the present invention provides a method for arranging four-in-one lamp beads in an LED display screen, comprising:

[0006] Divide the spherical LED display screen into unit modules;

[0007] The unit module lamp beads are preliminarily arranged;

[0008] The jagged edges formed by arranging the lamp beads are gradually optimized.

[0009] In some embodiments, when the spherical LED display screen is divided into unit modules, the unit modules have an arc shape or a trapezoidal shape.

[0010] In some embodiments, the steps of performing preliminary arrangement of the unit module lamp beads include:

[0011] Determine that the distances between the lamp beads at the corners of the unit module and the two adjacent sides are equal;

[0012] Arrange the lamp beads on the four sides of the unit module;

[0013] Fill the empty space in the middle of the unit module with lamp beads.

[0014] In some of the embodiments, when arranging the lamp beads on the four sides of the unit module, when arranging the lamp beads on the side or upper and lower sides of the unit module, the lamp beads arranged on the same side should be at the same distance from the side or upper and lower sides.

[0015] In some embodiments, the step of gradually optimizing the jagged edges formed by arranging the lamp beads includes:

[0016] Measuring any angle of the unit module, the angle is a;

[0017] Measure the number of lamp beads arranged on the non-hypotenuse side of the angle, which is n;

[0018] For the xth lamp bead on the edge, rotate it counterclockwise with its own center as the circle point, and the rotation angle is a-2xa / n;

[0019] Repeat the above operation for other edges until all edges of the unit module are optimized.

[0020] In some of the embodiments, in the gradient optimization, when x=n / 2, the rotation angle is 0; if n / 2 is not an integer, the optimization is terminated.

[0021] In a second aspect, the present invention further provides a four-in-one LED display lamp arrangement device, comprising:

[0022] A splitting module is used to split the spherical LED display screen into unit modules;

[0023] An arrangement module, used for preliminarily arranging the unit modules;

[0026] An angle unit, used to measure the angle of any corner of the unit module;

[0027] The rotation calculation unit is used to calculate the angle that needs to be rotated during lamp bead optimization.

[0028] In a third aspect, the present invention further provides a four-in-one lamp bead arrangement system for an LED display screen, comprising: the four-in-one lamp bead arrangement method for an LED display screen provided in the first aspect.

[0029] In a fourth aspect, the present invention further provides a storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the four-in-one lamp bead arrangement method for an LED display screen provided in the first aspect.

[0030] Compared with the prior art, the beneficial effects of the present application are: different from the prior art, the four-in-one lamp bead arrangement method for the LED display screen provided in the embodiment of the present application divides the spherical LED display screen into sections and arranges the lamp beads according to the angle of the module after division and rotates them by a certain angle, giving priority to the consistency of different modules after splicing, and taking the splicing edge as the basis. When arranging, the lamp beads are not restricted to a rectangular array, and each lamp is flexible and changeable, so that the entire LED display screen looks uniform and consistent, thereby improving the display effect and display quality of the spherical or special-shaped LED display screen.

[0037] In order to be able to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] See also Figure 1 , Figure 1 This is a flow chart of a method for arranging four-in-one lamp beads on an LED display screen according to an embodiment of the present invention, including:

[0039] Step S110, dividing the spherical LED display screen into unit modules; specifically, the spherical LED display screen commonly seen on the market currently has a basic unit with an arc shape. To facilitate production, most manufacturers will continue to simplify the arc shape with a curvature to approximate a series of isosceles trapezoids. After the spherical LED display screen is cut into a series of flat trapezoidal units, the lamp beads of the unit modules can be arranged.

[0040] Step S120, the unit module lamp beads are preliminarily arranged; however, according to the traditional method, a rectangular array arrangement is made, which will cause jagged edges on the unit modules. And as the irregularity of the unit module increases, the jagged seams will become larger and larger, forming a black hole area, affecting the display effect of the entire screen. To avoid affecting the display effect, please refer to Figure 2 , Figure 2 The process flow for preliminarily arranging the lamp beads of the unit module in the four-in-one lamp bead arrangement method of the LED display screen includes: step S121, determining that the distance between the lamp beads at the corners of the unit module and the two adjacent sides is equal; taking the lamp bead A at the corner as the first reference point, measuring the vertical distance between the lamp bead A and the upper base X of the trapezoid as L1, and the vertical distance between the lamp bead A and the hypotenuse Y as L2. In order to ensure that after the modules are spliced ​​into a screen, all the lamp bead spacings are similar and the pixels are uniform, it is necessary to ensure that L1=L2 holds. Step S122, arranging the lamp beads on the four sides of the unit module; the same method can be used to determine the coordinate positions of the lamp beads at the other three corners of the trapezoidal module. Step S123, filling the vacant positions in the unit module with lamp beads.

[0041] Step S130, perform gradient optimization on the jagged edges formed by arranging the lamp beads. After the above two steps, a four-in-one lamp bead arrangement similar to the module shape has been obtained. Compared with the conventional arrangement method, the area of ​​the black hole area is reduced, but there are still jagged gaps when viewed from a close distance. To solve the jagged edge problem, please refer to Figure 3 , Figure 3 This is a flow chart of the gradual optimization steps in the four-in-one lamp bead arrangement method of the LED display screen in the embodiment of the present invention; it includes:

[0042] Step S131, measuring any corner of the unit module, the angle of which is a;

[0043] Step S132, measuring the number of lamp beads arranged on the non-hypotenuse side of the corner, the number is n;

[0044] Step S133, for the x-th lamp bead on the edge, take its own center as the dot and rotate counterclockwise, the rotation angle is a-2xa / n; for example, the first lamp bead on the left, take its own center as the dot and rotate counterclockwise, the rotation angle = α; the second lamp bead on the left, take its own center as the dot and rotate counterclockwise, the rotation angle = α-2α / n; the third lamp bead on the left, take its own center as the dot and rotate counterclockwise, the rotation angle = α-4α / n; the x-th lamp bead on the left, take its own center as the dot and rotate counterclockwise, the rotation angle = α-2xα / n; when x = n / 2, the rotation angle is 0. If n / 2 is not an integer, ignore this step and terminate here. Step S134, repeat the above operation for other edges until all edges of the unit module are optimized.

[0045] Through the four-in-one lamp bead arrangement method of the LED display screen of the present invention, the original jagged edges of the spherical screen lamp beads no longer exist after splicing, because the two rows of lamp beads close to the hypotenuse are parallel to the hypotenuse and have equal vertical distances, so the two rows are also parallel and equidistant, ensuring the uniformity of pixels on the screen.
