LED display applications more and more in recent years, especially in the stage, LED rental demand trends, but at lease the stand or fall of a lot of the LED screen difficult points, if because of quality problems in the performance, causes the incident occurred, that is bad, in order to let the tenant know LED part of the assembly of device parameters, all rent machine network are all detailed introduction:
1. LED display screen rental brightness
The brightness of the LED display depends on the brightness of the beaded light. The higher the luminosity of the light, the greater the current balance is used, and the more energy is saved. At the same time, the lamp bead of LED has different Angle value. When the brightness of the chip has been determined, the Angle is smaller, and the brighter the light, the smaller the Angle of the LED screen will be.
2. Lease LED screen perspective
The Angle of the LED display is also related to the Angle of the light bead. In general, the horizontal Angle of the LED screen used in the outdoor is 100 degrees, while the ellipse LED is 50 degrees perpendicular. While indoor use is horizontal vertical slice of the LED120 degree, the tenant should make visual selection according to the actual needs and USES in the real lease.
3. Lease LED display screen life
General quality pass the service life of LED devices in 100000 hours, compared with the other much long service life of the display device, in order to prolong the service life of LED display, general leasing company will recommend lease tenants choose high quality.
4. Lease LED display attenuation characteristics
The use of LED screen for too long will reduce the brightness of the display, the use of long and color inconsistency problem may come up, a lot of tenants may not know about this problem, in fact, this problem cause reason is that the LED brightness attenuation caused by device, attenuation of LED devices will lead to a drop in brightness, red, blue, green three LED brightness attenuation is differ, so lead to show color is not consistent.
5. Lease LED display screen anti-static ability
LED for semiconductor devices, originally due to static electricity failure, thus makes the service life of the display is reduced, in order not to let the service life of the display screen is reduced, the LED of the human body electrostatic test failure power cannot be lower than 2000 v.
