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.
