What is Direct View LED
NEC's Direct View LED is a video display technology that uses Light Emitting Diodes to produce the red, blue and green colors typically found in a full color video display. Because the LED's are an emissive light technology, they provide images that are brighter and higher in contrast than the transmissive technology of traditional LCD displays. This easily allows for usage in nearly any environment while providing the eye catching content needed for digital signage applications.
What is an LED?
A light emitting diode (LED) is a tiny, electronic semiconductor that converts electric energy into visible light. The chemical compound used within an LED determines its color, brightness and power efficiency.
Each full color pixel in an LED display is comprised of 1 Red, 1 Blue and 1 Green LED. The combination of these three colors enables the LED to create over 16.7 billion colors in every pixel.
The distance between each LED pixel is known as the pixel pitch. This distance is measured in millimeters. The smaller the distance between each LED pixel, the more pixels on the display to create the image. This increases the display's resolution allowing for more detail to be seen in the image. This clearer image allows the optimal viewing distance to be shorter.
