[0027] Below, combined with the attached Figure 1 To the attached Figure 4 As well as specific implementation methods, the present invention is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] The embodiment of the present invention provides a color-free LED display screen based on an all-in-one device, such as Figure 1 and Figure 2As shown, it includes a display panel 1, an all-in-one device, and a display unit 2. The display unit 2 is arranged on the display panel 1 through an array of all-in-one devices. The all-in-one device is a prior art. Compared with the existing installation process, the all-in-one device has excellent moisture and humidity resistance, better patch effect, and most importantly, it is convenient to install the display unit 2. The display panel 1 includes a light board and a package, and the display unit 2 is arranged between the sealing board and the package. The display unit 2 includes a plurality of arranged pixel units 3, each of which includes a plurality of light-emitting pixel points 4. The light-emitting pixel points 4 include a green light pixel point 42 located in the middle and a blue light pixel point 43 and a red light pixel point 41 located on both sides. The light-emitting pixel points 4 are arranged in a straight line according to a preset arrangement rule. The arrangement rule includes a sequence rule for arranging the light-emitting pixel points 4 according to a preset order and an angle rule for arranging the light-emitting pixel points 4 according to a preset direction. The light-emitting pixel points 4 are patch light-emitting diodes. The green light pixel point 42 is a green light diode, the blue light pixel point 43 is a blue light diode, and the red light pixel point 41 is a red light diode. The diodes are installed on the display panel 1 through an all-in-one device. Compared with the existing manufacturing process, the all-in-one device can solve the process difficulty of mounting multiple LEDs in different directions, making production efficiency higher and product design difficulty lower. In addition, the all-in-one device has a stronger anti-collision ability, making the display screen more stable. Specifically, the sequence rule includes a light-emitting scheme 1 in which the light-emitting sequence is blue, green, and red, and a light-emitting scheme 2 in which the light-emitting sequence is red, green, and blue. The sequence rule in the same display unit 2 includes light-emitting scheme 1 and light-emitting scheme 2. The angle rules include horizontal angle rules, vertical angle rules and tilt angle rules. The angle rules in the same display unit 2 include at least two angle rules among the horizontal angle rules, vertical angle rules and tilt angle rules, thereby ensuring that each display unit 2 has enough pixel units 3 in multiple directions, thereby avoiding polarization problems.

[0029] like Figure 2 As shown, in some embodiments, the display unit 2 includes 16 pixel units 3, and the array of the pixel units 3 is a regular array of 4 columns and 4 rows, wherein the pixel units 3 in each row or column include pixel units 3 arranged using the light emission scheme 1 and the light emission scheme 2, and the pixel units 3 in each row or column include pixel units 3 arranged using the horizontal angle rule and the vertical angle rule. Figure 2 In the display, each column or row has the following pixel units 3: vertical pixel units 3 using solution 1, vertical pixel units 3 using solution 2, horizontal pixel units 3 using solution 1, and horizontal pixel units 3 using solution 2. Therefore, no color cast problem will occur whether the display is observed horizontally or vertically.

[0030] like Figure 3As shown, in some embodiments, the display unit 2 includes 9 pixel units 3, and the array of the pixel units 3 is a regular 3 columns and 3 rows, wherein the pixel units 3 located at the four corners of the display unit 2 adopt a tilt angle rule and the pixel units 3 at the four corners are symmetrically distributed around the center of the display unit 2, and the tilt angle rule generally adopts a clockwise tilt of 45 degrees and a counterclockwise tilt of 45 degrees. The pixel units 3 located in the second row and the second column adopt the horizontal angle rule and the vertical angle rule to form a cross shape. The order rule adopted by the pixel units 3 in the display unit 2 is not unique. Either scheme one or scheme two can be used. When the display units 2 are arranged in a row, the cross shapes between the display units 2 and the adjacent display units 2 can be connected to each other. Therefore, at this time, no matter whether the display screen is observed from the horizontal or vertical direction, there will be no color cast problem. At the same time, the diagonal lines between the display units 2 and the adjacent display units 2 will form a connecting line. Therefore, at this time, there will be no color cast problem when observing the display screen from other inclined angles. At the same time, the display units 2 can be combined and packaged. When the overall assembly is carried out, the combined and packaged display units 2 are used as units for individual mounting. In this way, there is no need to identify the pixel direction during mounting, and the colors between each display unit 2 will not be severely cast, and the installation speed can be accelerated.

[0031] like Figure 4 As shown, in some embodiments, the display unit 2 includes 9 pixel units 3, and the pixel unit 3 array is a regular array of 3 columns and 3 rows. Among them, the pixel units 3 located at the four corners of the display unit 2 adopt a regular tilt angle, and the tilt angle rule of the pixel units 3 at the four corners of the adjacent display unit 2 is different. This embodiment can also be combined and packaged to speed up the assembly speed, but it is different from the conventional method. Figure 3 The embodiment shown differs in that Figure 4 In the illustrated embodiment, the pixel units 3 at the four corners and the pixel units 3 in the adjacent display units 2 do not form connecting lines but form specific angles.

[0032] like Figure 5 As shown, the display unit 2 includes 4 pixel units 3, and the array of the pixel units 3 is a regular 2 columns and 2 rows, wherein the pixel units 3 in each row or column are arranged according to a vertical angle rule, and the pixel units 3 in each row or column include pixel units 3 set using light-emitting scheme one and light-emitting scheme two.

[0033] like Figure 6As shown, in some embodiments, the light-emitting pixel points 4 are arranged in a triangle, with the blue pixel point 43 or the red pixel point 41 at the tip of the triangle, and the other two light-emitting pixel points 4 on a straight line. In this embodiment, the blue pixel point 43 is at the tip of the triangle, and the red pixel point 41 and the green pixel point 42 are on a straight line. The order rules include scheme three in which the tip of the triangle is at the top and scheme four in which the tip of the triangle is at the bottom. The display unit 2 includes 4 pixel units 3, and the pixel unit 33 array is a regular 2 columns and 2 rows, wherein the pixel units 3 in each row and each column include pixel units 3 set using scheme three and scheme four. In the figure, the first pixel unit 3 in the first row adopts scheme four, the second pixel unit 3 in the first row adopts scheme three, and the close part between the two pixel units 3 is Figure 6 The A area in the figure contains three types of light-emitting pixels 4 and is in a triangular shape. When multiple display units 2 are required to be arranged in combination, the adjacent parts between adjacent display units 2 are Figure 6 Regions B and C in the image contain three triangular luminous colors respectively. Therefore, the luminous effects of regions A, B, and C are not much different from those of a single pixel unit 3, and the arrangement of multiple pixel units 3 will not produce polarization.

[0034] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
