LED illumination in a video wall offers you an array of performance enhancements – both in image quality and cost of ownership. By replacing the color wheel and UHP lamp with high power solid state light emitting diodes (red, green and blue LEDs) you achieve a much wider color gamut resulting in a much richer visual experience for your display. There is also a 25% increase in perceptional brightness as the Six-fold LEDs deliver much more saturated colors. With a brightness output of 750/1100 lumens, Delta’s LED video walls are the brightest in the market. LED-lit Video-walls also help control the brightness and contrast of your image more accurately.
With their extremely long lifetime (Eco mode 80,000hrs), LEDs do not need regular replacement, meaning you will have no consumables up to 6 years – even with a 24/7 operation & also possible to replace on-site whenever required. As LED is a flat light source (compared to a point light source of a lamp), they offer higher reliability. Even if one or two LEDs fail there is no loss of complete image & content is still displayed using balance LEDs. All this translates into lower maintenance and thus a lower total cost of ownership.
Because the red, blue and green LEDs can be sequenced at much higher rates than a color wheel, there is less chance of generating sequencing artifacts.

Unlike lamps which may take over a minute to turn on and reach full brightness, LEDs turn on instantly.
Containing no lead or mercury, the solid state devices comply with the RoHS directive for easy disposal
