LCD Televisions

LCD Televisions - By: Elizabeth Morgan, Posted on: 2006-07-21

LCD televisions are flat panel televisions that utilize LCD technology, which is already commonly been used in cell phones, calculators, and computer monitors. LCD televisions’ display screen has two parallel polarizing panels and a liquid crystal sandwiched between them. Based on the amount of voltage passed through the panels, the rod-shaped liquid crystal molecules will be untwisted to different degrees, limiting the entry of light. Thus, the crystalline layer acts a shutter that either allows or blocks the passage of light. As a result, dark and light patterns are formed on the display, which produces a magnificent picture.

A white backlighting is required in LCD televisions since the LCD pixels do not emit light as in Plasma televisions. In this, each color pixel is generated by three sub-pixels with red, blue, and green color filters. Unlike plasma and CRT ones, LCD televisions do not have a phosphor dot coating. Hence, they are thin and require much less power to operate than standard television screens.

Initial problems with LCD televisions were restricted viewing angle and difficulty in displaying fast-moving action. However, technology has advanced and the problem has been overcome in recent years. LCD televisions with wider viewing angles are now available. Better screen quality, longer life, and higher reliability are the core features of LCD televisions.

Compared to CRT televisions, LCD televisions have improved picture clarity and a flicker-free screen. LCD television monitors come have dual inputs to connect to the computer whereas others feature built-in speakers or jacks for microphones and headphones. The LCD television screen can be positioned in the landscape mode (longer than wide) and portrait mode (taller than wide).

LCD televisions are the best options for TV, video, and data display. LCD televisions can also be used as computer monitors. They come in a variety of sizes, from the tiny ones that fit in cabinets to the large home theater types.
