backlit

A backlight is a form of illumination used in liquid crystal displays (LCDs). As LCDs do not produce light by themselves (unlike for example Cathode ray tube (CRT) displays), they need illumination (ambient light or a special light source) to produce a visible image. Backlights illuminate the LCD from the side or back of the display panel, unlike frontlights, which are placed in front of the LCD. Backlights are used in small displays to increase readability in low light conditions such as in wristwatches, and are used in smart phones, computer displays and LCD televisions to produce light in a manner similar to a CRT display. A review of some early backlighting schemes for LCDs is given in a report Engineering and Technology History by Peter J. Wild under its section Backlit LCDs.
Simple types of LCDs such as in pocket calculators are built without an internal light source, requiring external light sources to convey the display image to the user. Most LCD screens, however, are built with an internal light source. Such screens consist of several layers. The backlight is usually the first layer from the back. Light valves then vary the amount of light reaching the eye, by blocking its passage in some way. Most use a fixed polarizing filter and a switching one, to block the undesired light.

    Amp with Backlit buttons

    Hi I like to listen to music in dim light and as I get older I find myself having to turn the light on to operate my hifi and wonder if anyone knows of a system that has backlit buttons: just an amp would do, but maybe an integrated system with a cd, DAB and receiver? Cheers Brendan

    Question Looking for a backlit bluetooth remote for general use

    Hi, I've got my system set up pretty much as I want it, and for the first time, most of the remotes work most of the other bits of gear. Unfortunately, none of them are backlit, and so I'm finding myself having to get up to turn the light on just to pause a film. Can anyone recommend a decent...
