Product Details

Full Color P2.976 LED Display Module

High brightness, low energy consumption, long life, reliable and stable, convenient application, simple maintenance, can bring higher quality image display effect and better user experience to users.


Remarks & Key Precautions

1.indoor P2.976 LED module can go with 500x500mm and 500x1000mm LED cabinet.

2.Indoor P2.976 led module’s Package: 2121.

3.Temperature requirement:

1) Operating temperature range: -20℃-45℃ other temperature range, need to install temperature control equipment.

2) Lamp surface temperature(working period): ≤60℃, temperature control equipment is required to be installed when temperature exceeding the standard.

4.Humidity requirement:

Storage humidity range: 10% RH-60% RH, humidity over 60% RH requires dehumidification treatment.

5.Keep away from water: Indoor LED module have low level of protection, water can make the module short circuit, and leads to circuit device damage, so it is necessary to keep away from the water source.

6.Sweat or other liquid cannot be dripped on the display screen during disassembly and assembly operation. If it is dripped, then use alcohol to clean the product, to prevent the liquid from corroding the LED module.

7.The indoor full-color LED display contains a driver chip and an input buffer chip, which can display video, image and text information when connected to the led display control system

in order to ensure the service life of LED, do not display only still picture or still text for a long time, and cause the lamp tube brightness serious attenuation or cause a batch of dead lights, please play the rolling picture or text.
