LCD Televisions

You may not be aware of it, but you have probably been using items containing LCD technology every day, they’re everywhere. From the digital clocks that one wakes up to every morning, to the watches worn to work, or the microwave ovens used to heat up that scrumptious breakfast, or what about the laptop computers that you carry almost everywhere, and not to mention the CD players that you frequently use to unwind from a stressful day. These are just some of the LCD-containing electronic devices that have become part of the daily routine; one device however, has become a very popular and favorite choice of people, the LCD television.

Liquid Crystal Display or LCD televisions are televisions that utilize the principle behind the LCD technology (flat, thin display device composed of several numbers of monochrome pixels displayed in front of a reflector or light source) for its image output. Generally, the technology employed is that of the ‘thin film transistor’ or TFT, which is a particular type of ‘field effect transistor’ made through putting thin films intended for metallic contacts, dielectric layer, and semiconductor active layer. The LCD television differs from the alternate image-producing technologies such as the plasma display or cathode ray tube.

Although LCD television had disadvantages in early years, for instance “ghosting” from fast-moving action or only best viewed through looking directly or slight angle at the screen, these drawbacks have mainly been conquered in recent years. LCD televisions, alongside plasma displays, have dominantly positioned themselves in the market worldwide. LCD televisions have the added benefit of being “electricity-efficient” than CRT televisions.

For quite some time, it was generally thought that the technology of LCD was only fit for smaller television sizes and could not contend with the plasma technology when it came to bigger sizes. The conviction was weakened after the statements of seventh-generation panels by corporations such as Samsung, Westinghouse Digital, Sony, Sharp Corporation, and LG-Philips LCD. In October of 2004, 40-inch to 45-inch LCD televisions was extensively available; and Sharp successfully manufactured a 65-inch panel. Samsung presented its 82-inch LCD panel in March of 2005, and the August of 2006 gave way to LG Philips’ 100-inch LCD television.

The contemporary LCD television sets are physically universal as they encompass a multi-system tuner that display NTSC, SECAM, and PAL standards. They also have an electronic transformer, which can automatically use 110/250 voltage AC responsively, and universal grounded adapter plugs. Additionally, most LCD televisions are no longer simply for television and HDTV, but they can also serve as computer monitors with VGA/DVI signal, though resolution support varies widely.

Manufacturers of LCD televisions have proclaimed plans of investing billions of dollars for the production of these panels over the next several years, with television market expected to become a key market.
