1. Choice of color display
First, consider your needs, whether you need to display text or images. If you only need to display text content, then choose LED single-color or dual-color screens. If you need to display documents, images, and videos, then choose a full-color LED screen.
2. Selection of point spacing
There are many specifications for the point spacing of LED displays, such as P0.9/P1.25/P1.53/P1.86/P2/P2.5/P3/P4, etc. These models are generally suitable for indoor use; P4/ Specifications such as P6/P8/P10 are generally suitable for outdoor use. Among them, the smaller the point spacing, the higher its resolution. The display effect is better, so these must be selected according to the environment and viewing distance. If the viewing distance is relatively close, then a small spacing LED display is needed to achieve a good effect on the large screen; if the viewing distance is far away, a small spacing is not required to achieve a clear display effect on the large screen.
3. Choice of brightness
The requirements for LED display screens to be used outdoors and indoors are different. For example, indoor brightness is required to be around 1000cd/㎡, while semi-indoor brightness is required to be around 2000cd/㎡, and outdoor brightness is required to be greater than about 4000cd/㎡. , so that you can see the screen display clearly when the light is strong.
4. Refresh rate selection
The LED display screen is divided into high brush and normal brush, which we cannot distinguish under normal circumstances. The difference can only be seen when shooting. The normal brush will have water ripples when shooting, and the shooting effect is very poor, while the high brush will have no effect.
5. Selection of control method
Common control methods for LED displays include wireless control, PF wireless control, GPRS wireless control, full network wireless control, fully automatic control, wired control, etc. You can choose the control method according to your own choice.
