Pixel QI - Brightness in any light

Pixel QI

Pixel Qi Corporation, the world’s only non-captive LCD screen designer, has pioneered a new class of screens combining an e-paper look with color and video. These screens offer dramatically lower power consumption, full sunlight readability, and stunning text rendering for reading. The screens use standard LCD manufacturing equipment and materials with a full suite of new inventions to give users real benefits they can see.

Pixel Qi, with offices in Silicon Valley, California and Taipei, Taiwan, is a spin-off of One Laptop per Child (OLPC) and was founded by OLPC‘s former CTO Mary Lou Jepsen. Pixel Qi believes that the future of computing is all about the screen and is dedicated to continuously delivering innovative screen technologies rapidly into high volume mass production.

Qi [noun] [pronounciation : chee]: the circulating life energy that in Asian philosophy is thought to be inherent in all things.

Pixel Qi - Technology - How it works





Reflective mode outdoors		Transflective mode in office environment

Pixel QI backlight turned off.		Pixel Qi backlight turned down to reduce power
Standard LCD can not operate at high
ambient light levels


			Color Part

			The transmissive color part of a 3Qi display
			s designed as known from an ordinary
			color LCD. Each individual pixel is divided
			into three cells, or subpixels with red, green
			and blue color filter. A LED backlight is
			placed behind shines through the layer of
			liquid crystal and the color filters whereas
			the orientation of the crystals controls
			the brightness of each color.
			Black-and-White Part
	3Qi is a combination of a standard transmissive color LCD and a very low power, high-resolution black-and-white display with 64 grey scales.		As soon as the backlight is switched off, the
			reflective black-and-white part uses the
			ambient light e.g. from a lamp or the sun
			which enters the display and is reflected by
			a mirror behind a large part of each pixel.
			On its way back the brightness of each
			subpixel is controlled by the liquid crystal
			similar to the color mode. In order to
			reduce loss of brightness, the color filters
			are dropped in this area. Therefore each
			subpixel becomes visible to the user as a
			black-and-white pixel with 64 grey-scales.
