[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely in the description of the embodiments of the utility model in combination with the drawings, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Referring to Figures 1-5 , the large viewing angle high-definition super-high-brightness LED display screen comprises a module display surface 1 and a module cover 2, the module display surface 1 is fixedly arranged on one side of the module cover 2, the other side of the module cover 2 is provided with a cooling fan 3, the outer side of the cooling fan 3 is fixedly connected with a mounting plate 4, the mounting plate 4 is fixedly connected on the other side of the module cover 2 through fasteners, the inner cavity of the module cover 2 is also symmetrically fixedly connected with two groups of LED display driving lamp plates 6, one group of LED display driving lamp plates 6 is connected with the module display surface 1 through a fiber-optic light pipe 7. Wherein, the cooling fan 3 draws external air into the inner cavity of the module cover 2, and the air inlet end and the air outlet end of the cooling fan 3 are both provided with filter screens 301, the two sides of the mounting plate 4 are provided with cooling air outlets 5 communicating with the inner cavity, the cooling air outlets 5 are connected with the part between the LED display driving lamp plates 6 and the inner wall of the module cover 2, the light emitting point spacing of the module display surface 1 is P6, and the lamp spacing of the LED display driving lamp plate 6 is P12.

[0026] Based on the above structure, when the device is designed, the pixel spacing is pulled apart, the heat dissipation area is increased, the pixel spacing of the LED display driving lamp plate 6 is designed as P12, the actual required pixel spacing is P6, so that an LED display driving lamp plate 6 with an area size greater than 4 times is required to be designed, due to the limitation of installation space, the present design is two lamp plates, and the area of the LED display driving lamp plate 6 is equal to 4 times the area of the P6 spacing lamp plate. The light of each pixel of the P12 LED display driving lamp plate 6 is extended to the P6 module display surface 1 through the light guide pipe, and photoelectric separation is formed.

[0027] Similarly, each module is designed with a module cover 2, and a heat dissipation fan 7 is installed, and a heat dissipation system is formed by a single module. Since the pixel spacing is P12, the conventional outdoor brightness design, the heat dissipation system only needs to circulate the air for heat dissipation;The module cover is convenient for module structure assembly, air circulation, screen installation and maintenance.
