Why is LED called luminous level and display screen 5?

LEDs, also known as light-emitting diodes, emit light when excited by an electric current. Of course, it can be called luminous.

One or many light-emitting diodes will emit light like a display, which can be called a cold light plate display

I learned it 2 years ago, and I don't know if it's right! ~

He itself is a light-emitting electronic component, due to the different materials and filling gases can emit different colors of light, with him to make a display is called LED display.

The name of the LED industry, the name of the display application.

LED display is an electronic display composed of LED dot matrix. The content form is displayed in the context of the content form, animation, and real-time transition, which is displayed by clicking on the traffic light. Component display control is performed by a modular structure.

It is mainly divided into display module, control system and power system. The display module is an array of LED light points to form screen lighting; The control system is to adjust the expansion of the area to convert the content displayed on the screen; The power system needs to convert the input voltage and current to meet the display.

First, the LED display components.

As a multi-tech product combining light, electricity and sound, the LED display system mainly includes the following parts.

Display body. Control host and communication system.

Sound equipment. System software.

External devices (video recorders, cameras, TV signals, etc.).

Second, the working principle of LED display.

A display that uses LED light-emitting diodes as the basic light-emitting devices. Generally, it is composed of a display module or box, a sending card, a receiving card, a processor, a multi-processor, a control system, a distribution box, etc.

Third, the characteristics of LED display.

1.Less power consumption, energy saving--- LED uses a low-voltage power supply, the power supply voltage is between 6-24V, which varies according to different products, so it is a safer power supply than using a high-voltage power supply, especially suitable for public places.

2.Long service life, stable performance, 100,000 hours, light decay is 50% of the initial.

3.Low cost.

4.Modular design, easy to install and maintain (can be maintained with electricity).

5.High brightness, large viewing angle, long viewing distance.

6.No pollution to the environment, no harmful metal mercury.

If you need professional scene-based lighting effects, you need professional lighting designers and executive teams to communicate and cooperate with each other according to the specific conditions of the venue, I hope it can help you.

Hello I am Shandong Yunfei Optoelectronics, focusing on the LED industry for more than ten years, LED display is a set of optoelectronic technology, microelectronics technology, computer technology as one of the high-tech products. Its light-emitting part is composed of LED (that is, light-emitting diode is the abbreviation of English light emittingdiode), which has the advantages of low power consumption, high brightness, low working voltage, simple drive, long life and stable performance. The display screen area can be assembled arbitrarily by the unit module according to its needs, with its rich colors, real-time dynamic display mode of patterns, perfect multi-professional effects, strong visual impact will be displayed in a variety of ways, such as information, text, animation, etc., and become an epoch-making product of information dissemination, which has been widely used in railway civil aviation, stadiums, conference halls, highways, squares, large shopping malls, markets and a variety of monitoring and scheduling.

LED display performance is outstanding:

1. Strong luminous brightness, when the sunlight hits the surface of the screen directly within the visual distance, the display content is clearly visible. Super grayscale control has 1024-4096 levels of grayscale control, the display color is above the color, the color is clear and realistic, and the three-dimensional sense is strong.

2. Static scanning technology, using static latch scanning method, high-power drive, fully guarantee the luminous brightness.

4. Imported large-scale integrated circuits are fully adopted, which greatly improves the reliability and is convenient for debugging and maintenance.

The screen resolution is 1920*800 led display.

The phase is high, and I can't see a little bit at close range. . . This is the most basic.
