2. Brightness
3. Grayscale
4. Length width ratio
5. Flatness
6. Refresh frequency

LED display has been developed since the 1980s. Not only has the technology made great progress, but also the market demand is growing. As an important media in our life, LED display is loved by all bosses. We all know that LED displays are also widely used, and we have seen them in many places. How to choose a high-quality LED screen? This problem is analyzed from the following six key factors.

 

1. Control mode

Our common LED display control methods include WIFI wireless control, RF wireless control, GPRS wireless control, 4G all network wireless control, 3G (WCDMA) wireless control, full automatic control, timing control, etc. Everyone can select the corresponding control method according to the needs.

2. Brightness

When purchasing an LED display screen, you must confirm in advance whether it is installed outdoors or indoors. Generally speaking, outdoor requires high brightness, which should be above 5000 cd/m, while indoor requires only 1800 cd/m. There are 6 major differences between indoor and outdoor LEDs.

3. Grayscale

Grayscale is related to brightness. It refers to the degree of brightness, that is, the so-called color scale or gray scale, which often determines the brightness of colors. Generally speaking, the higher the gray level is, the richer the color is, and the more beautiful the effect is.

 

4. Length width ratio

The length width ratio of LED display screen will directly affect the viewing effect, so the length width ratio of LED display screen is also an important factor to be considered in the selection. Generally, the image text screen has no fixed proportion, which is mainly determined based on the content to be displayed, while the common aspect ratio of video screen is 4:3.

5. Flatness

When touching the LED display screen, there is no roughness, which is called "flatness" in the industry. Although many people tend to ignore this when purchasing, LED display screen with high flatness is a good screen.

In general, the smaller the flatness, the smoother the screen display, the more uniform the color, and the better the viewing effect. On the contrary, the screen is prone to distortion and the viewing effect is poor.

6. Refresh frequency

The refresh rate refers to the number of times the screen is refreshed by the screen per second. Generally speaking, the higher the refresh rate, the more stable and smooth the screen display. The lower the refresh rate, not only will there be ugly water ripples, but also will affect the eyes and make people feel uncomfortable.
