​indoor LED digital display It uses an array of light emitting diodes as pixels for video displays. LED Digital Displays can provide higher contrast ratios than projectors and are therefore an alternative to traditional projection screens, and they can be used for large, uninterrupted (no visible grid on the sides of a single display) video walls. For more about the LED Digital Display, please read the following words.

​The decline of the traditional advertising industry and the increase in the permanently installed outdoor LED display advertising also confirm the unprecedented benefits of permanently installed Outdoor LED Digital Displays.

​With the rapid development of Outdoor LED Digital Display, LED display manufacturers have also sprung up, so how do you choose the Outdoor LED Digital Display products suitable for your project?

The indoor LED digital display uses a low-voltage DC supply voltage and is therefore particularly safe to use. Both older and small children can safely use it without causing safety risks. The normal inrush current of indoor LED digital display is: 20mA; The voltage is 5V. It can drive the presentation forward, which shows that its security is the premise guarantee.

​The Indoor LED Digital Display can reproduce various texts, images, animations, and video signals such as TV and VCD so that it is widely used in many places in interiors.

​The indoor LED digital display adopts low-voltage scanning drive, which has the advantages of low power consumption, long service life, low cost, high brightness, large viewing angle, long viewing distance, waterproof, and multiple specifications.

The service life of indoor LCD digital display can reach more than 50,000 hours. LCD splice screens are widely used in information display terminals in airports, ports, docks, subways, highways and other transportation industries, shipping services, control rooms, radio and television, large studio of performance venues, military, government, city and other emergencies command systems and other places!

Indoor LCD Digital Display​ is a liquid crystal display, which is a display device, which consists of two upper and lower glass, polarizer, liquid crystal and ITO film, etc.

​The structure of indoor digital LCD display is to place liquid crystals in two parallel pieces of glass. Between the two panes of glass there are many vertical and horizontal thin wires. The rod-shaped crystal molecules are controlled in such a way that they change their direction and refract the light, regardless of whether they are electrified or not. Generate screen.

The basic principle that Indoor LCD Digital Display can display is to fill liquid crystal material between two parallel plates, and to change the arrangement of molecules inside the liquid crystal material by voltage, so as to achieve the purpose of shading and transmitting light to display different shades and scattered patterns. image, and as long as a three-color filter layer is added between the two flat plates, the display of color images can be realized.
