From the application environment, indoor and outdoor requirements for LED display hardware and software are also different. Therefore, when we are renting outdoor LED screens, we cannot consider it from the perspective of renting indoor LED screens, but should depend on the specific situation. What should we pay attention to when renting outdoor LED display screens?
1. Dead Spot
LED rental screen dead point refers to a single point that is always bright or always black on the screen, and the number of dead points is mainly determined by the quality of the die. The fewer dead spots, the better the display will be.
2. Display brightness
Since the outdoor light is very sufficient, refraction and reflection will occur, resulting in unclear visibility on the screen. Therefore, the brightness of outdoor LED rental screens should be high. Above 4000cd/㎡, the brightness of products of different brands will vary. Indoors are just the opposite. Too high brightness will easily damage the vision, and too low brightness will cause the display image to be unclear. Therefore, the indoor brightness is generally 800cd/㎡-2000cd/㎡.
3. Color reproduction
The display color must be highly consistent with the color of the playback source to ensure the realism of the image.
4. Splicing flatness
The outdoor LED rental screen is spliced into a large screen in units of cabinets, and the surface flatness of the cabinet is required to be kept within ±1mm. Partial protrusions or recesses on the surface of the cabinet will lead to a dead angle in the viewing angle of the rental screen. The quality of flatness is determined by the manufacturer's production process, so it needs to be controlled by the manufacturer and must have strict production and testing standards.
5. Viewing angle
The size of the viewing angle of the outdoor LED rental screen directly determines the size of the audience. The larger the viewing angle, the better, and the audience will be wider. The viewing angle is affected by the packaging method of the LED die. Therefore, be sure to pay attention to the die packaging method.
In addition, when using outdoor rental LED displays, you should also pay attention to:
1. When opening the screen: first open the control host, then open the screen; when closing the screen: first close the screen, then close the control host. If you turn off the computer without turning off the display screen, it will cause the screen to appear bright spots and burn the lamp). The time interval between switching on and off the screen should be greater than 10 minutes. After the computer enters the engineering control software, the screen can be powered on.
2. During the operation of the LED rental screen, when the ambient temperature is too high or the heat dissipation conditions are not good, do not open the screen for a long time; the power switch of the display screen often trips, you should check the screen body or replace the power switch in time; check the connection regularly firm condition. If there is any looseness, pay attention to timely adjustment, re-reinforce or update the hanging parts; according to the environmental conditions of the rental LED display screen and the control part, avoid insect bites, and place anti-rat medicine if necessary.
