Embodiment 1

[0036] like figure 1 , 2 As shown, the LED display module 1 includes a bottom case 11, a face shield 13, a lamp board 12 and an LED lamp installed on the lamp board 12. The LED lamp is exposed to the outer surface of the face shield 13, and the bottom case 11 is in the shape of a square as a whole, and is obtained by integral molding, such as casting, blister or blow molding, to facilitate processing and obtain better structural strength. Bottom shell 11 comprises head 111 and body 112, as figure 2 , 3 As shown, the head is provided with a power line interface 1112 and a signal line interface 1111, and the body 112 is provided with a plurality of long and narrow through holes 1123, and the whole is in the shape of a grid. The main body 112 is provided with ribs 1121 on the side opposite to the mask 13 , and the ribs 1121 are arranged corresponding to the positions of the grilles to play a role of reinforcement. The height of each rib 1121 gradually decreases from one end ...

Embodiment 2

[0041] like Figure 5 , 6As shown, this embodiment takes the P25 grid-type LED display as an example, which includes 8 LED display modules 1, 1 module box 2, and 2 two L-shaped protective strips 2, 8 LED display modules Group 1 is divided into 4 groups, arranged in two rows from top to bottom, every two LED display module heads 111 are arranged side by side relative to each other, the thickness of the module box 2 and the height of the rib 1121 close to the head 111 Correspondingly, the cover is arranged on the head 111 of each LED display module 1 , and the module box 2 is fixed and sealed to the head 111 . The module box 2 not only plays the role of covering the head 111, avoiding the exposure of the interface of the power line and the signal line, but also plays the role of strengthening the structural strength of the whole product. Two L-shaped protective strips 2 are respectively arranged on the two sides of the P25 LED display screen, that is, the floating ends of each...

Abstract

The invention provides a grid-type light emitting diode (LED) display screen and a module thereof. The module comprises a bottom shell, a mask and an LED lamp, wherein the LED lamp is arranged on the bottom shell and exposed from the external surface of the mask; the bottom shell comprises a head part and a body; the head part is provided with a power cord and a signal wire interface; a plurality of elongate through holes are formed in the body, and the body is in grid type; through holes corresponding to each elongate through hole of the bottom shell are formed on the bottom shell and a lamp plate respectively; a ribbed plate is arranged on one side of the body opposite to the mask; and the ribbed plate corresponds to each grid part. The module is suitable for industrialization, is produced in large batch, light in weight, difficult to twist and deform, and excellent in permeability.

Description

technical field [0001] The invention relates to LED display technology, in particular to a grid-type LED display screen and a module thereof. Background technique [0002] LED display (LED display): also known as electronic display or floating word screen. It is composed of LED dot matrix, and displays text, pictures, animations, and videos through the LED electronic display screen by turning on and off the red or green lamp beads. The content can be replaced at any time, and each part of the component is a display device with a modular structure. It usually consists of a display module, a control system and a power supply system. The display module is composed of a dot matrix of LED lights, which is responsible for luminous display; the control system can display text, pictures, videos and other content on the screen by controlling the corresponding areas to be on and off. The input voltage and current are converted to the voltage and current required by the display. [...
