QD Vision's Color IQ™ product platform is targeted at several major opportunities in the consumer electronics industry, including LCD TVs, monitors and mobile display applications. These initial applications alone represent more than a $1-billion addressable market by QD Vision's quantum dot-based products.
- Color IQ™ is an ideal solution for display applications, delivering such benefits as:
- Color gamut performance that achieves 100% of the NTSC standard
- The color performance of OLED TVs at a price comparable to typical LCD TVs
- Color Purity: Highly saturated, precisely tunable colors for more vivid color images
- Stability: Inherent material reliability and color balance stability
- Design Flexibility: Thin structures that can be efficiently used for any size display
In addition to its focus on developing Color IQ solutions for display backlight units (BLUs) used in products including mobile devices, laptops, and TV and computer monitors, the company also plans to apply its expertise to develop quantum dot-based displays, which can be commercialized in the next few years.
QD Vision projects that its Color IQ solutions for backlighting units will provide more highly saturated color and better contrast between the darkest blacks and the whitest whites.
A major trend in the LCD industry is to replace CCFL fluorescent lights with LEDs in BLUs. Today, most LCD makers use white LEDs and integrate them into side illuminated light guides, which provide the light for the display. Red, green and blue light is separated from the white spectrum of the LED by color filters, and much of the original spectrum is lost or wasted as heat. This solution leaves much to be desired. First, it is extremely energy inefficient, as only approximately 5-to-7 percent of the backlight illumination makes its way to the viewers' eyes. Second, the color quality or gamut is reduced due to the initially incomplete white spectrum of the starting LEDs. Finally, this approach requires many more LEDs than necessary.
Color IQ enables the use of highly power efficient blue LEDs. It converts a portion of the blue LED light into deep red and green light, creating tri-chromatic (red, green and blue) white light, which then gets coupled into the light guide. The use of this tri-chromatic white light composed of highly saturated colors improves color gamut of the LCD from about 60-70 percent of the NTSC standard to 100 percent, making a brilliant, colorful image.
