LED display (LED panel): LED is light emitting diode, the English abbreviation of light-emitting diode, referred to as LED. It is a display method by controlling semiconductor light-emitting diodes. Its general appearance is composed of many light-emitting diodes, usually red, and characters are displayed by turning on and off the lights. A display screen used to display various information such as text, graphics, images, animations, market prices, videos, and video signals.

LED has a low working voltage (only 5V), can actively emit light and has a certain brightness, and the brightness can be adjusted by voltage (or current), and it is shock-resistant, anti-vibration, and has a long life (100,000 hours)

LED display (LED display, LED Screen): also known as electronic display or floating word screen. It is composed of LED dot matrix and led pc panel. It displays text, pictures, animations and videos by turning on and off the red, blue, white and green LED lights. The content can be replaced at any time, and each part of the components is a display of modular structure. device. A traditional LED display is usually composed of a display module, a control system and a power supply system. The display module is composed of a dot matrix composed 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 light of the corresponding area. The color screen is mainly for playing animation; the power supply system is responsible for converting the input voltage and current into the voltage and current required by the display screen.

The reason why LED has been widely valued and developed rapidly is inseparable from its own advantages. These advantages are summarized as follows: high brightness, low operating voltage, low power consumption, large size, long life, impact resistance and stable performance.

1. Features of LED display

1. High brightness: the brightness of the outdoor LED display is greater than 8000mcd/㎡, which is the only large-scale display terminal that can be used outdoors all day; the brightness of the indoor LED display is greater than 2000mcd/㎡.

2. Long life: The life of LED is more than 100,000 hours (10 years). This parameter generally refers to the design life, even if the brightness is dim;

3. Large viewing angle: the indoor viewing angle can be greater than 160 degrees, and the outdoor viewing angle can be greater than 120 degrees. The size of the viewing angle depends on the shape of the LED light emitting diode.

4. The screen area can be large or small, as small as less than one square meter, and as large as hundreds or thousands of square meters;

5. Easy to interface with computer, rich in supporting software.

2. There are five common installation methods for LED display screens:

Embedded installation

It is suitable for indoor screens with small area. Due to the small installation space, in order not to take up space, dig out the same size area on the wall according to the size of the screen, and embed the led display in the wall. The walls are required to be solid walls. The cost of using the front maintenance method is relatively high.

Hanging installation

It is mostly suitable for large-scale places such as station LED electronic display screens and airport LED electronic display screens to play the role of indicator signs. The screen area is required to be small (less than 10 square meters), and it is required to have a suitable installation location, such as a beam or lintel on the top, and the screen body generally needs to be covered with a back cover.

wall mount

It is mostly suitable for the installation of indoor LED display screens. The area is small (less than 10 square meters), and the wall is required to be a solid wall. Hollow bricks or simple partition walls are not suitable for this installation method.

Roof Mount

It is mainly suitable for outdoor advertising led electronic display screens. The installation location is mainly the roof of the building. As the height of the building increases, the windproof level to be considered also increases.

Column Mount

It is mostly used for the installation of outdoor advertising LED display screens, where the field of view is wide and the surroundings are relatively open, such as squares, parking lots, etc. According to the size of the screen body, it can be divided into single column and double column installation.

3. Content selection and design

LED large screens are public media, including public welfare, advertising, and instructions. When we choose the content to broadcast, we must reach an agreement with the public's requirements to avoid refusal to watch. This is also an important aspect of preventing and controlling light pollution on display screens.

The LED diode itself is a green light source. Although it does cause a certain degree of colored light pollution on the large LED display screens used in clusters due to design considerations and application requirements, this contradiction must exist, and cannot be completely eradicated. Only by adopting technical means and policies and regulations to minimize color light pollution, coordinate the needs of advertisers and the viewing psychology of the public. At the same time, we have also seen that compared with today's neon lights and white light box advertisements, the light pollution of LED displays has been greatly reduced. Moreover, the LED electronic display also has the advantages of energy saving and rich colors, and it will definitely replace the outdoor lighting and information display of neon lights in an all-round way.
