Embodiment Construction

[0033] see figure 1 , figure 1 It is a schematic cross-sectional structure diagram of the first embodiment of the LED display device of the present invention.

[0034] The LED display device 10 includes an LED display panel 1, the LED display panel 1 includes a circuit board 11, and a plurality of LED pixels 13 formed on the circuit board 11 and composed of light-emitting elements of different primary colors, each of the The LED pixel 13 may include one LED element, or may include a plurality of LED elements, and there are LED element solder joints 12 between the LED elements. If each of the LED pixels 13 includes a red LED element, a green LED element and a blue LED element, each of the LED pixels 13 can emit full-color light.

[0035] The LED display device 10 also includes an isolation barrier 2, and a diffusion screen 3 arranged in front of the isolation barrier 2, and the isolation barrier 2 covers the LED display panel 1 except for the light-emitting positions of the p...

Abstract

The invention provides an LED display device, comprising an LED display panel. The LED display panel comprises plural LED pixels constituted by different fundamental color luminous elements; The LED display device also comprises a separation grid covering on the LED display panel and a diffusing screen arranged in front of the separation grid; the separation grid is used for separating each pixelon the LED display panel. In the LED display device provided in the invention, the separation grid is used for separating each pixel on the LED display panel and reducing mutual crosstalk of the light emitted by each pixel; and the diffusing screen is used for diffusing the light of LED pixels towards each direction and amplifying the visible size of the LED pixels, enabling the light emitted by the LED display device to be softer and more uniform, and improving the picture display quality of the LED display device.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to an LED display device. Background technique [0002] LED display is mainly used in outdoor advertising. It has high brightness and can be seen clearly from a long distance. Although the pixel pitch is large, it will not affect the display effect due to the long viewing distance. In recent years, with the advancement of technology, the dot pitch of LED displays has become smaller and smaller, reaching the level of 2 to 3mm, and LED displays have gradually entered indoor applications. [0003] An important part of the existing LED display screen is the LED display panel. There are two ways to realize the usual full-color LED display screen. One is to assemble multiple red, green, and blue LED elements together to form an LED pixel. One is three-in-one, that is, the red, green, and blue primary color LED elements are packaged together to form a component (usually SMT), and then...
