4. Product Components and Technologies:
LED light
We use high-end chip-packaged LED lights from world-renowned manufacturers to provide customers with a variety of choices. At the same time, the service life and display quality of the display are fully guaranteed.
SMDfull color 2121 series: full black bodyDriver IC
It adopts high refresh rate, high grayscale constant current driver IC from the world's leading manufacturers, with excellent driving performance, stable and reliable.PCBboard
The multi-layer circuit design is used to ensure uniform current distribu tion on the light panel and good heat dissipation, prevent color blocks from appearing under low grayscale conditions, and enhance anti-electromagnetic interference capabilities.
The boards are made from high-quality manufacturers in the industry: Shengyi, Jiantao (KB), etc.Drive and control
Each module is controlled by an independent control card, which has higher integration, stronger stability, better display e ect and high refreshed
dedicated 14BIT high grayscale, high refresh drive constant current IC, unique blanking circuit, protects LED, prevents surge leak age; supports system multi-channel redundant backup
module point-by-point chromaticity correction, and double power supply backup.

6. OPERATE
This product is powered by DC +5V (operating voltage: 4.5~5.2V).AC power supply is prohibited; the power terminals are prohibited from being connected reversely.
If this product is faulty during the warranty period, please send it back to our company for repair, or perform repairs under the guidance of our after-sales personnel.
When disassembling/installing the product, be sure to operate carefully to avoid tools hitting the product.
Lightning protection and anti-static work should be done during operation and use; the box and steel structure should be grounded.
During use of this product, the power cannot be turned on and o continuously. The two operations should be separated by at least 1 minute.
This product cannot be turned o for a long time. It is recommended to use it once every half month and power it on for 4 hours. In a high-humidity environment, it is recommended to use it once a week and power it on for 4 hours.
This product does not allow playing the highest brightness all-white picture for more than half an hour. It is recommended to play mainly dynamic videos.
7. CLEAN
To clean the surface of the module, please use a soft-bristled brush and brush gently. It is prohibited to use any liquid substance to clean the surface of the LED module, otherwise the SMD LED may be damaged.
8. Moisture-proof and storage requirements
After opening the package, SMD LED products must be stored in an environment with a temperature <30°C and a humidity <60%.
If the screen has not been used for more than 3 days, the preheating lighting method needs to be used every time the screen is lit: 30%-50% brightness is preheated for 4-8 hours, and then adjusted to normal brightness (80%-100%) lights up the screen body to eliminate moisture so that there is no abnormality during use.
