But without the backlight on, it's rather hard to see the top LCD without some light shining on it.
Backlit LCD displays direct light up through the display into the user's eyes.

This will include expanding production lines to manufacture ultra-high resolution liquid crystal display (LCD) and organic light emitting diode (OELD) display panels.
The display's backlight has nanopatterned grooves that send blue, green and red in multiple directions, letting the LCD show only the light that would be seen from a given viewpoint.

The new LCD technology also improves the light transmittal of pixels, rendering brightness with an added benefit of lower battery drain.

The company is in the process of holding an expo in Tokyo, where they've lined up some leading Japanese manufacturers to show off their latest gear, along with concept products that will never see the light of an LCD screen.
The PT-AE8000U generates deeper blacks by incorporating Panasonic's Pure Contrast Plates, which match the LCD panel characteristics, virtually eliminating light leakage.
Made of shatter-proof plastic, the Reflex LCD is ultra-thin and light.
N-trig's digitizers are easily integrated into existing technologies, support any type of LCD, and keep devices slim and light.

Amazon's light guide technology precisely diffuses the light across the screen and only requires four LEDs to light the entire screen (unlike LCD screens which can use up to 50 LEDs).

The lenses of its battery-powered glasses are actually tiny LCD screens that open and close like shutters, letting light in selectively.

This air gap allows light to come through the touch sensor and reflect off the LCD, which causes added glare for the user.
Corning is also pushing new glass products such as Willow Glass, a super-thin, flexible glass, and Lotus Glass, for use in organic light-emitting diode (OLED) and next-generation LCD displays.

Light-based communication seems to wind throughout the MIT Media Lab -- it is a universal language, after all, since many devices output light, be it with a dedicated LED or a standard LCD, and have the capacity to view and interpret it.
If Friend's discovery lives up to its promise, the LCD will someday be tossed aside in favor of the OLED--organic light-emitting display.
The UCLA engineers have created a novel concept for harvesting and recycling energy for electronic devices - one that involves equipping these devices' LCD screens with built-in photovoltaic polarizers, allowing them to convert ambient light, sunlight and their own backlight into electricity.
ENGADGET: Photovoltaic polarizers could make self-charging smartphone dreams come true
The UCLA Engineering team created a new type of energy-harvesting polarizer for LCDs called a polarizing organic photovoltaic, which can potentially boost the function of an LCD by working simultaneously as a polarizer, a photovoltaic device and an ambient light or sunlight photovoltaic panel.

While LCD screens need a backlight to illuminate their crystals, OLED does not need a separate light source.
Whether a light and portable long-zoom camera, or a sharp and stylish dual LCD model, the new cameras introducing this technology deliver the combination of image quality and connectivity that today's consumer needs.

An integration of ICC (Integrated Cognitive Creation) technology, developed by I3 (I-cubed) Research Center, and Sharp large-screen panel technology that gives a resolution four times that of conventional full HD LCD panels, the ICC-LED TV reproduces the cognitive process by which the human brain interprets light stimuli, resulting in on-screen images that approach true-to-life quality.

Kindle Fire HD solves this air gap problem by laminating the touch sensor and the LCD together into a single layer of glass, creating a display that's easy to view even in overhead light, and reducing glare by 25% relative to iPad 3.
