LCD Display

A liquid crystal display or a liquid crystal display (English liquid crystal display, LCD), is a screen or a display (English display), whose function is that it is affecting liquid crystals, the polarization direction of light when a certain level is applied to electrical voltage.

LCDs consist of segments that can change independently of each other their transparency. This is controlled with electrical voltage in each segment the orientation of liquid crystals. This changes the transmittance of polarized light that is generated with a backlight and polarization filters.

If a display can display arbitrary content, the segments in a uniform grid are arranged (see pixels). For devices that are intended to represent only certain characters, the segments often a specially selected form, especially in the seven-segment display for displaying numbers (see also matrix display).

A further development is the active-matrix display that provides a matrix for the control of thin film transistors (English thin film transistor, TFT). In flat panel technology that is currently (late 2007) is predominant.

In advertising since about 2009 is often spoken of LED TVs. These are in most cases still around for liquid crystal displays (LCDs) imaging, but the backlight is implemented with new LEDs (LED backlight). Displays with organic light emitting diodes (OLEDs) are for large-scale televisions is not yet widely available.

LCDs are used in many electronic devices, such as in consumer electronics of measurement devices, mobile phones, digital watches and calculators. Even head-up displays and video projectors use this technology.
