Do you have to know these points when buying led screens? The choice of led screen should be carried out in accordance with many factors such as one's own needs, site constraints, and investment. For example, whether the led screen is used indoors or outdoors, the main purpose of the led screen is to display text, or to play various video signals, images and texts, etc., the viewing distance of the led screen and the control method (synchronous control, asynchronous control or Wireless control, etc.) are all very important factors.

  Generally speaking, if the image requirements are high and the visual distance is short, then choose a display with a high dot density; if the text playback is large, choose a specification with a low dot density. In addition, you should choose a full-color or monochromatic display screen according to the investment situation, choose different frame materials according to the decoration situation, and choose different control methods according to the characteristics of use.

  The led screen display screen is divided into indoor and outdoor according to the use occasion, and divided into monochromatic text, two-color text, and full-color screen according to the color. LED screens used outdoors should have high brightness and good visual effects under the sun. Due to the large viewing distance outdoors, the diameter of the LEDs is relatively large, and they must be used all-weather, windproof, For protection against lightning, rain, and mildew, the diameter of the indoor screen is smaller than that of the LED, generally from 0.8 to 5 mm. The monochrome screen is red or green, and is usually only used for text display. The two-color text screen can display red, green, and yellow, and the pixel density can be as high as tens of thousands of dots per square meter.

  The quality factors of led screens include viewing angle, brightness, uniformity, refresh speed, non-linear correction and so on. Depending on the brightness and color of the screen, the power consumption varies greatly, from more than 100 watts per square meter to more than 1,000 watts per square meter.
