1. Basic knowledge of LED display and LCD
1). LED display
LED display, to put it bluntly, is a bunch of light-emitting diodes (LEDs) put together. Each LED is a small light point. These light points are arranged according to certain spacing and specifications to form the pixels we see.
By controlling the brightness and color of each LED, just like playing a puzzle, you can piece together various images and texts. Moreover, the working principle of the LED display is very smart.
It uses PWM (pulse width modulation) technology, which is to quickly switch on and off the LED lights so that our eyes feel that the brightness is changing so that different pictures can be displayed.
There are many kinds of LED display screens, such as:
The pixel pitch of this display screen is very small, generally less than 2 mm. You can’t see a single LED clearly even if you look closely. The picture is super clear and is especially suitable for indoor use, such as conference rooms and TV stations.
The pixel pitch is larger, and it can be used indoors and outdoors. It can be seen on billboards and stadiums.
This is the coolest. It can be bent and curved. You can make any shape you want. The creativity is endless!
The advantages of LED display screens are many:
높은 명도: It is dazzlingly bright. It is not afraid of sunlight when used outdoors, and it is also very bright when used indoors.

High initial cost: In comparison, LED displays are more expensive when they are first purchased, especially those with small pitch and flexible ones.
2). LCD display
LCD display is a liquid crystal display. It has two pieces of glass with liquid crystal in the middle. By applying voltage to the liquid crystal, the arrangement of the liquid crystal can be changed to control the transmission of light.
In this way, the image can be displayed. In order to display color, LCD also uses red, green and blue filters, just like a palette, to adjust various colors.
There are also several types of LCD displays:
TN-LCD: This is the cheapest and has a fast response, but the viewing angle is small, the brightness is low, and the color is not very accurate.
VA-LCD: The viewing angle is large, the color is accurate, and it is suitable for viewing high-definition pictures.
IPS-LCD: The color, viewing angle, and response speed are all good, and it is used in professional applications.
The advantages of LCD displays are also many:
