  1. Backlight

    A backlight is a form of illumination used in liquid crystal displays. As LCDs do not produce light themselves, they need illumination 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 in 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 by Peter J. Wild IEEE First-Hand History under its section Backlit LCDs. Simple types of LCD displays are built without an internal light source, requiring external light sources to convey the display image to the user. Modern LCD screens, however, are built with an internal light source. Such LCD screens consist of several layers. The backlight is usually the first layer from the back. But in order to create screen images, a mechanism is needed to regulate the light intensity of the screen's pixels. For this, light valves are used that vary the amount of light reaching the target by blocking its passage in some way. The most common element is a polarizing filter to polarize the light from the source in one of two transverse directions and then passing it through a switching polarizing filter, to block the path of undesirable light.

Examples of backlight in a Sentence

  1. New Zealander Jackson:

    I'd never worked with him or even met him before, but he'd shot the Babe films and I thought they looked amazing, the way he'd used backlight and the sun and natural light to create a very magical effect, and Babe had that larger-than-life feel about it that I wanted.

  2. Leia CEO David Fattal:

    It's a very simple LCD technology, which is the technology that equips most of the cell phones and most of the regular displays today. As we essentially change just one small chief component which is called the backlight and we introduce our nano technology on to it. It sounds very scary but actually it's very benign and cheap to do. And out of this we're able to send rays of light into space instead of disorganized light that would propagate in all directions.
