Matte Matte
The actual picture of the screen body
Matte screen, anti-glare
Resistant to moisture, fingerprints and knocks
Lamp plate protection class IP5
Panel hardness 4H
Surface can be scrubbed with water, anti-static, anti-oxidation
New optical material surface treatment, anti-scratch, anti-fingerprint, anti-bump
Low temperature liters and low power consumption
At room temperature, the white equilibrium temperature is less than 45°C
Power consumption of a single cabinet ≤75W
Power consumption per square meter ≤370W
COB flip chip
- The chip is welded directly on the PCB board,
without welding line,
effectively reducing the failure rate
