Problems solved by technology

In this way, there will be obvious patchwork, and the phenomenon of TV wall will appear, which will affect the display effect.
[0004] 2. Due to the strength requirements, the larger the size of the glass or plastic plate, the thicker the thickness is required, resulting in a larger weight
[0005] 3. It is difficult to fix the glass or plastic plate, which will cause a difference in the distance from the LED lamp surface, resulting in inconsistent display effects and affecting the display effect

Embodiment Construction

[0027] It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] like figure 1 As shown, the LED display device of this embodiment includes an LED display panel 1 and a mask. The mask is arranged on one side of the LED display panel 1 , and the mask includes a plurality of light-transmitting cover units 10 , and each light-transmitting cover unit 10 is bonded to the LED display panel 1 . A positioning structure is provided to define the sticking position of each light-transmitting cover unit 10 on the LED display panel 1 . Through the positioning of the positioning structure, the position where the light-transmitting cover unit is connected to the LED display panel is more accurate, thereby helping to reduce the splicing gap...

Abstract

The invention provides a light-emitting diode (LED) display device which comprises an LED display panel (1) and a face guard. The face guard is placed on one side of the LED display panel (1) and comprises a plurality of light transmission cover units (10) which are pasted with the LED display panel. Positioning structures are placed between the light transmission cover units (10) and the LED display panel (1) to limit the pasting positions of the light transmission cover units (10) on the LED display panel (1). Each light transmission cover unit (10) is provided with a first side (11) and a second side (12), wherein the fist side (11) faces the LED display panel (1), the second side deviates from the LED display panel (1), and a grating structure is placed on the second side (12). The LED display device is small in splicing gap, good in evenness and display effects.

Description

technical field [0001] The present invention relates to the technical field of LED display, and in particular, to an LED display device. Background technique [0002] With the development of the display screen market, naked-eye 3D display devices are applied in fields such as advertisement display. In the prior art, it is realized by adding glass or plastic plates outside the display screen, and pasting grating molds on the glass and plastic plates. But the above structure has the following defects: [0003] 1. Considering transportation and other reasons, the size of the glass or plastic plate is limited, so that the display screen cannot be enlarged infinitely, and can only be limited to a certain size. If the size exceeds a certain size and needs to be spliced, the glass or plastic plate needs to be fixed by a frame after splicing, that is, each glass or plastic plate has a frame in the circumferential direction. In this way, there will be obvious seams, and the phenom...
