There are various large display devices popular in the market. LED display screen has technical advantages that other display screens cannot match.
LED display screen is a high-tech product that integrates optoelectronic technology, microelectronic technology, computer technology and video technology.
Its light-emitting part is composed of LED (light-emitting diode is the abbreviation of English light emitting diode), which is characterized by low power consumption, high brightness, low working voltage, low power consumption, miniaturization, easy matching with integrated circuits, simple driving, long life, impact resistance and stable performance.
The display area can be assembled arbitrarily by unit modules according to needs. With its rich colors, real-time dynamic display mode, perfect multimedia effects and strong visual impact, it can display information, text, pictures, animations, videos and other ways.
It has become an epoch-making product for information dissemination and has been widely used in railways, civil aviation, stadiums, conference halls, highways, squares, large shopping malls, securities markets and various monitoring and dispatching.
1. Long service life: The service life of light-emitting diodes is more than 100,000 hours
2. Fast response speed: This is a common feature of semiconductor devices
3. Long visible distance: The single point diameter of LED can reach 52mm, and the visible distance is more than 500 meters
4. Many specifications and varieties: LED display screens are indoor and outdoor, with monochrome, two-color and full-color
5. High degree of digitization: Fully digitalized, high-resolution graphics can be achieved
6. High brightness: It can be used outdoors, such as traffic lights, anti-fog lights, etc. And the brightness can be automatically and flexibly adjusted according to the different brightness requirements of sunny and cloudy days or morning and afternoon
7. Large viewing angle: indoor display screen can reach 160 degrees, outdoor can reach 120 degrees
8. Low power consumption: the maximum power consumption per square meter does not exceed 800w
Indoor and outdoor display screen
The display screen is divided into outdoor display screen and indoor display screen according to the scope of use. The outdoor display screen is mainly used for: city squares, commercial pedestrian streets, convention and exhibition centers, stadiums, trading markets, road traffic, airports, stations, docks and other public places to display various information
It has the following technical features
1. Excellent effect: dynamic scanning technology is adopted, the picture is stable, without noise, the image effect is delicate and clear; the animation effect is vivid and diverse;
2. The video effect is smooth and realistic
3. Advanced technology: the outdoor display screen adopts static drive, and the adoption of non-linear chromatic aberration correction technology makes the color uniform
4. Convenient maintenance: modular design, easy installation and maintenance, and can be repaired with power
5. Excellent quality: imported luminous materials, high-quality IC chips, noise-free high-power power supply
6. Flexible format: the display mode can be arbitrarily arranged by the user
7. Rich content: text, charts, images, animations, video information can be displayed
8. Large amount of information: the amount of information displayed is not limited
9. Computer control is used, the operation is convenient and flexible, and the picture is clear and stable.
10. Rich and bright colors, high image brightness, colors can be divided into monochrome, three colors or 65536 colors and true color.
11. It can display both text and graphics, with rich fonts.
12. The viewing angle is large. In direct sunlight, the image on the outdoor display screen is still clearly visible within a range of 150 meters.
13. The video function is advanced. In addition to displaying graphic information, the display screen can also be connected to external devices such as DVDs to play TV pictures.
14. Networking of display screens: A microcomputer can simultaneously control multiple display screens to display different contents, and the display screen can work offline.
15. The display screen has complete supporting software, excellent performance, easy use, stable and reliable.
