The principle of LED display module and the principle of the system, specifically, thank you

The system is composed of computer special equipment, display screen, input port and system software. The computer and special equipment directly determine the function of the system, and different types can be selected according to the different requirements of the user for the system. The control circuit of the display receives the display signal from the computer, drives the LED to emit light to produce a picture, and outputs the sound by adding power amplifiers and speakers.

**Input port provide** input port, the signal Nayou source can be a video recorder, DVD player, video camera, etc., support NTSC, PAL, SVIDEO and other standards. The system software is available with LED** special software, PowerPoint or ES98**** software.

The LED electronic display system takes the computer as the processing control center, the electronic screen corresponds to a certain area of the computer display (VGA) window point by point, the display content is synchronized in real time, and the screen mapping position is adjustable, which can be convenient to choose the size of the display screen with the wishes of the company.

The display dot matrix adopts ultra-high brightness LED light-emitting tube (red and green dual primary colors), 256 levels of grayscale, 65536 color change combinations, rich and realistic colors, and supports VGA 24-bit true color display mode.

Equipped with ** information and 3D animation ** software, ** high-quality ** information and 3D animation. **There are more than 10 forms of software display information, such as covering, closing, opening the curtain, alternating colors, zooming in and out, etc.

Using special program** software, you can add, delete and modify text, graphics, images and other information through different input methods such as keyboard, mouse, scanner, etc. The orchestration is stored on the hard disk of the control host or server, and the order and time of the program are alternated with the integration of high and high performance, and can be superimposed on each other. It can receive and display the first signal of the video recorder, DVD player, etc.

Summary. Hello kiss, I am glad to answer the question for you, the principle of LED display is to use the characteristics of LED (light-emitting diode) to control the positive and negative voltage of LED to make it emit light, so as to form a display effect. The principle of LED display is to form a group of LEDs into a pixel, then a plurality of pixels into a module, and finally a plurality of modules into a display screen, by controlling the positive and negative voltage of the LED, so that it emits light, so as to form a display effect.

Hello dear dear is glad to answer for you, the principle of LED display is to use the characteristics of LED (light-emitting diode) to control the positive and negative voltage of LED, so that it can emit light slowly, so as to form a display effect. The principle of LED display is to form a group of LEDs into a pixel, then a plurality of pixels into a module, and finally a plurality of modules into a display screen, by controlling the positive and negative voltage of the LED, so that the disturbance of its light is emitted, so as to form a display effect.

Kiss, LED display: LED display working principle - (1) system composition This system is composed of computer special equipment, display screen core, input port and code tremor system software.

The intrinsic characteristics of LED determine that it is the most ideal light source to replace the traditional light source, and it has a wide range of uses. Its advantages are: small size, low power consumption, long service life, high brightness, low heat, high brightness, low heat, environmental protection, and durability.

Let's make it simple and easy to understand.

LED light-emitting diode is a solid-state semiconductor device that can directly convert electricity into light. The heart of an LED is a semiconductor wafer with one end attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire wafer is encapsulated by epoxy resin. A semiconductor wafer is made up of two parts, one is a p-type semiconductor, in which holes dominate, and the other end is an n-type semiconductor, which is mainly electrons here.

But when these two semiconductors are connected, a "p-n junction" is formed between them. When an electric current is applied to the wafer through the wire, the electrons will be pushed to the p-region, where the electrons will recombine with the holes, and then the energy will be emitted in the form of photons, which is the principle of LED luminescence.

The old 7 embedded LED dynamic pixel map dynamic display principle, a moving picture is indispensable for two elements, namely frame and time.
