What is led display and what does display led mean

Question: What is led display?

That's a good question.

Because of the publicity problems of some businesses, the concept of LED display, LCD screen and OLED screen is mixed.

In fact, these three kinds of screens have nothing to do with it, and the display imaging principle has nothing to do with it. Let's not talk about those esoteric display imaging principles, just talk about the application scenarios of these three screens, and everyone will understand.

LED Display:Banks, small shops, hotels and other places on the door of the red font word screen, roadside super-large full-color advertising screen are LED displays. LED display is unique in the field of super-large size (tens of square meters, or even 100+ square meters).

LCD screen:Computers and TVs are mainstream with LCD screens. In the past, mobile phones also used LCD screens, and now mobile phones have a general trend of using OLED, one of the reasons is that OLED is thinner than LCD.

But the cost of OLED is much higher than that of LCD.

OLED Display:The Honor Band, the Xiaomi Mi Band, and the well-known phones that have just been launched, the Huawei Mate 40 and the Apple 12, all use OLED screens. Now, the use of OLED screens for small-size screens is the general trend.

Upstairs is so professional, the biggest advantage of the LED display is that it can be customized according to the size, and you can do it as big as you want.

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 (LED display) is a flat panel display, composed of a small LED module rubber panel, used to display text, images, ** and other information equipment, so what does the display LED mean?

1. The structure of LCD is to place the liquid crystal box in two parallel glass substrates, set TFT (thin film transistor) on the lower substrate glass, and set up a color filter on the upper substrate glass, and control the rotation direction of the liquid crystal molecule through the change of signal and voltage on the TFT, so as to control the polarized light of each pixel to achieve the purpose of display.

2. Light-emitting diodes are referred to as LEDs. It is made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc. When electrons and holes are recombined, they can dissipate and radiate visible light, so they can be used to make light-emitting diodes.

It can be used as an indicator light in circuits and instruments, or as a text or digital display. Gallium arsenide diodes glow red, gallium phosphide diodes glow green, silicon carbide diodes glow yellow, and gallium nitride diodes glow blue. Due to its chemical properties, it is divided into organic light-emitting diode (OLED) and inorganic light-emitting diode (LED).

3. LED as the backlight of liquid crystal display, it can not only be used as green, red, blue, white, but also as a color-changing backlight. Recently, the LCD screen on the mobile phone uses LED to make the backlight, which improves the grade of the product, and the effect is very good. 15in (1in LCD screen backlight) made of 8 blue, 24 green, 32 red LUXEONLED, can reach 120W, 2500LM, brightness 18000nits (nits, cd m2).

22 LCD screen backlight has also been made, only 6mm thick, not only good color mixing effect, color rendering index also reached more than 80.

That's it for the introduction of what the display LED means.
