P20 RGB LED Matrix Message Display EN12966 NTCIP VMS Traffic Control
En12966 VMS Traffic Sign P20 RGB Led Dot Matrix Display Module NTCIP 65kg/M²
Application:
It is widely used in highway tunnel, urban road, dense section of road network of main trunk line, urban road, street, airport, wharf, station and other traffic guidance and related application fields.
--Sleep mode:
YHT-VMS product,in the blank area, only a 10uA current will flow in each channel under sleep mode. A sample calculation for energy saving is showingas follows. YHT-VMS product will save around 800 times for every single IC driver than general VMS!
--Dual Voltage
Due to lighting chip difference inside, Red/Amber LED has lower threshold voltage to light up than Green/Blue LED. So, we applied dual voltage channel to drive two types of LEDs. Surplus energy is saved by this technology. Using separate voltage driving board to achieve energy-saving purpose:specific voltages are applied to different lamps.
1, Module package uses advanced soft silicone, the elastic, strong anti-aging ability.
2, Power supply, it is important IC device through the heat sink cooling, not only solve the heat, but also to ensure the performance is unstable due to mechanical failure when the cooling fan caused.
3, Use special wide temperature range of the device, ensure the normal operation of the display at high or low temperatures.
The control system only with the IPC, and higher reliability.
4, Use of sophisticated large-scale integrated chip high-speed serial transmission network alternative to discrete parallel transmission chip, reducing the complexity ofthe transmission display, reducing the complexity of the control system to improve the stability of the prod
uct.
5. Support four primary colors randomly matched display, highlighting, high transparency.
6. Exquisite structure design, each luminous pixel luminous uniform, no Mosaic phenomenon;
7. Support manual and automatic schedule intelligent brightness adjustment.
