LCD/Liquid Crystal Display (LCD)

An LCD Display that uses _____ backlighting to light the display. ______ has lower power consumption than standard LCD backlighting, allows the panel to be thinner, lighter, brighter, and display better contrast.

Light Emitting Diode (LED)

Display uses a layer of organic material that responds to electrical stimulus to emit light. This process allows each pixel to light individually, resulting in much deeper black levels than LED. Displays are also thinner and lighter than LED displays.

Organic LED (OLED)

displays are another type of flat panel monitor that can achieve high levels of brightness, deep black levels, and a very wide range of colors. Display get their names from the use of tiny cells of ionized gas that light up when stimulated by electricity.

Plasma

Is a projection technology. Projectors use a spinning color wheel with a microprocessor controlled array of mirrors called digital micromirror device (DMD). Each mirror corresponds to a specific pixel. Each mirror reflects light toward or away from the projector optics.
