Design and manufacturing features:
(1) High density, small dot pitch design
(2) Small display unit, box assembly structure
(3) High heat dissipation efficiency packaging technology
(4) The internal extremely uniform light mixing, the brightness is divided by 1:1.1 times, and the wavelength is divided by 2.5nm
(5) High fill factor, low black area ratio, large display surface luminous body, reducing the graininess of the display surface
(6) Compact RGB chip three-in-one layout package
Common cathode energy saving LED Display:
The energy-saving screen and ordinary LED display heat contrast when the same current passes.
Ordinary LED display The energy-saving LED DISPLAY
