400mm*300mm die-cast Aluminum cabinet 4k high definition TV wall
1, contrast LEDs, 3 in 1 with black surface
2, High refresh rate, MIB5153 FM-PWM drive IC
3, Perfect low grey technology, 16bit grey scale
4, Ultra-light Weight: 4.6kg/cabinet
5, Die-cast aluminum cabinet with side lock to avoid black and white lines
6, 4K Hight Definition TV wall
High refresh rate:
Delicate and smooth picture at high speed shutter, without ripple or flicker; vivid video to restore true picture;
Visual fresh rate over 3000hz, high performance led display;
High refresh rate with stable video play and less flash;
Low fresh rate results in horizontal stripes with camera, and also damage to eyes for too much flash lights.
High grey scale:
Rich color leave with low brightness, gradient color gradation excessive smoothly, making perfect performance.
Normally high quality led display has grey scale of above 14 bit, with color range of 16384
Low grey scale means insufficient color degree or unsmooth color gradation, which is not able to play good video, decreasing ROI of advertiser.
Some poor quality led display is detected some clear color blocks with 1/500 shutter.
High efficiency:
20% utilization and 20% luminance higher than traditional LED display to enhance the utilization rate of driving circuit and lamp.
High utilization the LED chip can display a maximum brightness (bit) Brighter than the low LED utilization system, (usually the LED utilization over 90% been called LED top utilization system.)
The only way to make the low LED chip utilization LED display system achieve high utilization of LED chip is increase the current through the LED chip.
However, this method will not only use more energy, and will also affect the speed of the current up and down when the driver chips in the case of the same switching time.
