Whether the outdoor display uses LED screen or LCD screen

Whether the outdoor display uses LED screen or LCD highlight LCD screen, each has advantages and differences ?



LCD mainly has TFT, UFB, TFD, STN and other types of liquid crystal display. The liquid crystal itself is not illuminating.

It can only rely on backlight transmission to make the screen display content. The brightness of ordinary LCD screen is only 500cd/m2. 

The outdoor direct sunlight has a brightness of 2000 cd/m2, which is generally invisible to the LCD screen. 

It is necessary to modify the backlight brightness to enhance the readability of the LCD screen under sunlight. 

However, in terms of display effect, the clarity and softness are better than the LED screen, and the LCD screen is less polluted 

by the environment because it is not a self-luminous material.


The LED screen is composed of a small LED module panel. One or more (different colors) single lamps can be used to form a basic pixel. 

Because of the high brightness, it is mostly used for outdoor display screens. 

The LED display can be arbitrarily extended and seamlessly spliced, and the LED display can be operated for five years or more. 

In terms of display effect, the LED display has a higher brightness, a wider viewing angle and a good color reproduction capability than the LCD screen. 

However, the brightness of the environment in different time and place changes greatly. If the brightness of the LED display is greater than 60% of the ambient brightness, 

we obviously feel the incompatibility of the eyes, which means that the light pollution of people is caused. The glass curtain wall already has relevant regulations, and it is believed that there will be relevant regulations on artificial chalk and color light pollution.
