LCD Monitor

by speree LCD (Liquid Crystal Display), for many of the users may be a term is not new, and there, but the history of this technology may be far beyond our imagination - as early as the 19th century, the Austrian botanist on the found in liquid crystal, that liquid crystals, a substance that is also equipped with liquid crystal liquidity and a similar arrangement of features. The role of the electric field under the arrangement of liquid crystal molecules will produce changes. Thereby affecting its optical properties, a phenomenon known as electro-optic effect. The use of liquid crystal electro-optical effect, in the last century, British scientists create the first liquid crystal display or an LCD. Today's LCD monitors are widely used in fixed linear liquid crystal, micro-look at it if we will find it special like a cotton swab. CRT compared with conventional, LCD is not only small size, the thickness of thin (the thickness of the current 14.1-inch machine can be achieved only 5 cm), light weight, low energy consumption (1 to 10 microwatts / square centimeter), low voltage (1.5 to 6V) and no radiation, no flicker, and can be matched directly with CMOS integrated circuits. Because a number of advantages, LCD since 1998 into the desktop applications. .
The first operational LCD based on the Dynamic Scattering Mode (Dynamic Scattering Mode, DSM), RCA's joynhmaner led the team developed the LCD. Hellman created Optel Inc., the company has developed a series based on this technology, the LCD. In December 1970, the rotation of nematic liquid crystal field effect in Switzerland cents special and Helfrich Hoffman - Le Locle central laboratory registered as a patent. In 1969, James Ferguson in the United States, Ohio Kent State University (Ohio University) found that the rotation of nematic liquid crystal field effect and in February 1971 in the United States registered the same patent. In 1971, his company (ILIXCO) produced the first based on such characteristics of LCD, a very high-speed cache on behalf of the poor performance of the DSM-type 7 inch LCD.
Years later in 1985, this discovery has generated a commercial value in Japan in 1973, Sampo, the first time it applied to production of electronic calculator figures. Now, LCD of the notebook and handheld computer's main display device, in the projector, it also plays a very important role, and it began to penetrate the desktop monitor market.
All along, the pursuit of a more perfect visual enjoyment are our goal of the desktop display devices, recalling the course of development in recent years, display technology, we can easily find that it is around the same theme - "the pursuit of a better visual comfort of the human eye," !
In recent years, suddenly, as the emerging new products, liquid crystal displays have been fully replace the bulky CRT monitors into the mainstream of current display devices. However, the liquid crystal display development road is not smooth sailing as we had imagined. Below, we look at the new and old players to LCD in recent years, the development of arduous and tortuous path.
LCD Early Development (1986 ~ 2001) - high cost-containment of its development road
First, the early immature technology, LCD is mainly used in electronic watches, calculators and other areas of
We usually say LCD, it is in English called the Liquid Crystal Display, directly translated into Chinese is a liquid crystal display, referred to as liquid crystal displays.
10.4 inch LCD Monitor is an almost completely transparent material. It is the molecular arrangement of liquid crystal determines the path of light penetration. To the 20th century, 60's, people discovered that charge will change its liquid crystal molecules are arranged in turn result in distortion or refraction of light, thus sparked the idea of invention liquid crystal display devices.
The world's first liquid crystal display device 70 appear in the early 20th century, was known as TN-LCD (twisted nematic) liquid crystal display. Although a monochrome display, it still extended to the electronic watches, calculators and other fields.
