Description

A LED display

【Technical field】

The utility model relates to an LED display screen.

【Background technique】

In today's era, with the continuous development of science and technology, LED display screens have been widely used in commercial advertisements. The display screen can form a large advertising screen or advertising characters. Because of its bright and changing colors, it is easier to attract consumers' attention in commercial applications, so as to achieve a relatively ideal publicity effect. Therefore, LED display is very popular among people.

However, most of the existing LED display screens are integral structures, that is, LED lights are arranged on a whole panel. Because of its large size, this display screen brings inconvenience to manufacturing, processing and installation. And packing and transportation are difficult, and cost is higher. The waterproof effect of this display screen is also not ideal, and the LED light is easy to cause a circuit short circuit fault after being exposed to water.

Therefore, the utility model makes further improvement at above-mentioned deficiency.

【Content of invention】

The purpose of the utility model is to provide an LED display screen, which is beneficial to manufacture, processing and installation. The packaging and transportation are very convenient, which reduces the cost. Moreover, patterns or characters are spray-painted on the panel of the display screen, so that the appearance of the display screen is more beautiful and the publicity effect is better.

The purpose of this utility model is achieved in that:

An LED display screen, which is characterized in that it includes a panel, a fixing frame, and a plurality of mutually independent elongated LED light bars are fixed on the fixing frame, and the LED light bars are arranged side by side. There are multiple groups of LED light groups distributed on the top; the panel is fixed on the upper surface of the LED light bar, and a through hole exposing the LED light group is provided on the panel.

The above-mentioned LED display screen is characterized in that patterns or characters are spray-painted on the panel.

The above-mentioned LED display screen is characterized in that the LED light bar includes a fixing seat and a circuit board, the fixing seat is upwardly shaped, and a card slot is provided at the open end of the fixing seat. The circuit board is fixed in the card slot.

The above-mentioned LED display screen is characterized in that the circuit board is covered with a waterproof sealant.

The above-mentioned LED display screen is characterized in that the fixing seat of the LED light bar is provided with through holes for connecting power lines and signal lines.

The beneficial effects of the utility model are: 1. The LED light bar constituting the display screen can be assembled and disassembled separately, which is beneficial to processing and manufacturing, and convenient for packaging and transportation; 2. A circuit board is arranged in the LED light bar, and the circuit board There is potting glue on the top of the board, so that the waterproof effect of the circuit board is better, and the service life of the circuit board is increased; 3. Graphics or text can be sprayed on the panel, so that the decorative effect and publicity effect of the display screen are better.

【Detailed ways】

As shown in Figures 1 to 4, a LED display screen referred to in the present invention includes a panel 1 and a fixing frame 2, on which a plurality of mutually independent elongated LED light bars 3 are fixed, The LED light bars 3 are arranged side by side. And on the circuit board of the LED light bar 3, there are multiple groups of LED light groups 4 distributed, and the LED light groups 4 constitute the pixel units of the display screen. The panel 1 is fixed on the fixing frame 2 on one side of the LED lamp group 4, and the through hole 5 exposing the LED lamp group 4 is provided on the panel 1, and the LED light bar 3 is arranged on the rear side of the panel 1, so that the display The appearance of the screen is more beautiful.

The utility model can spray patterns or characters on the panel 1, so that the decoration effect and publicity effect of the display screen are better.

In this embodiment, the LED light bar 3 includes a fixing seat 6 and a circuit board 7, the fixing seat 6 is ㄩ-shaped, and a card slot 8 is provided at the open end 60 of the fixing seat 6, and the circuit board 7 is fixed in the card slot 8. And the circuit board 7 is covered with potting glue 70, so that the circuit board 7 is not easy to be corroded by water, avoiding the circuit short circuit fault caused by the circuit board 7 being stained with water, thereby increasing the service life of the circuit board 7.

The fixing seat 6 of the LED light bar 3 is provided with a through hole 9 for connecting the power line and the signal line. The through hole 9 is sealed to prevent rainwater from entering the fixing seat 6 from the through hole 9 .

The utility model can separately manufacture and process the LED light bars constituting the display screen, and only need to arrange the LED light bars side by side and fix them on the fixing frame 2 when the display screen is installed. This facilitates the installation and disassembly of the display screen, reduces the volume during manufacturing and processing, and reduces the cost of packaging and transportation.
