The LED display is also called an electronic display or a floating word screen. It is composed of LED dot matrix and led pc panel. It displays text, pictures, animations and videos by turning on and off the red, blue and green LED lights. The content can be replaced at any time. All components are modular display devices. A traditional LED display is usually composed of a display module, a control system and a power supply system. The display module is composed of a dot matrix composed of LED lights, which is responsible for luminous display; the control system can display text, pictures, videos and other content on the screen by controlling the light of the corresponding area. The color screen is mainly for playing animation; the power supply system is responsible for converting the input voltage and current into the voltage and current required by the display screen.

The LED color screen is simpler than the LED display screen, and the dot pitch of the color screen is larger to be used in large-area display effects, and the low cost is an advantage. The following introduces the difference in characteristics between the two:

Features of LED color screen:

The LED color screen is composed of LED dot matrix. It displays text, pictures, animations and videos by turning on and off the red, green and blue lamp beads. The content can be replaced at any time. Each part of the component is a display device with a modular structure. It usually consists of a display module, a control system and a power supply system. The display module is composed of a dot matrix of LED lights, which is responsible for luminous display; the control system can display text, pictures, videos and other content on the screen by controlling the corresponding areas to be on and off. The input voltage and current are converted to the piezoelectric current required by the LED color screen.

1. Modular design, easy to install and maintain.

2. The all-aluminum structure module weighs only about one-third of the conventional display screen, and has good weather resistance.

3. The transparent design does not affect the ventilation and lighting at the rear of the screen, and the wind resistance is small.

4. Energy saving and environmental protection, no need for auxiliary cooling equipment, natural air cooling, no noise.

5. It is more suitable for the production of large-area display screens.

6. Designed for creative indoor and outdoor installations that emphasize long-distance viewing effects and transparency.

7. Fast installation, light transmission, ventilation, large pixel pitch, high cost performance.

8. Bright colors, fast response, good display effect, high reliability, long life, and environmental protection and energy saving;

9. The fanless design of the whole screen, no noise, low power consumption, can be used in the temperature range of -30℃~60℃


10. The screen body is made into vertical strips or grids, and the size can be adjusted arbitrarily


11. Easy production, maintenance, good heat dissipation, high stability


12. It is mainly used as background for indoor and outdoor concerts, building curtain walls, advertising screens, nightclubs, dance halls, etc


Features of LED display


1. High brightness: the brightness of the outdoor LED display is greater than 8000mcd/m2, which is currently the only large-scale display terminal that can be used outdoors all-weather; the brightness of the indoor video wall display LED display is greater than 2000md/m2


2. Long life: The life of LED is more than 100,000 hours (10 years). This parameter generally refers to the design life, even if the brightness is dim


3. Large viewing angle: the indoor viewing angle can be greater than 160 degrees, and the outdoor viewing angle can be greater than 120 degrees. The size of the viewing angle depends on the shape of the LED light-emitting diode


4. The screen area can be large or small, as small as less than one square meter, and as large as hundreds or thousands of square meters


5. Easy to interface with computer and support rich software


6. Comparison of common large display terminals.
