TFT-LCD technology, detailed process
Working principle of TFT-LCD liquid crystal display
With the maturity of TFT technology in the early 90s, the development of color LCD flat panel display, less than 10 years, the rapid growth of TFT-LCD into the mainstream display, which has its advantages are inseparable. Main features are:
(1) good use characteristics
The application of low voltage, low driving voltage, solid use safety and reliability is improved; flat, and thin, save a lot of raw materials and the use of space; low power consumption, the power consumption is about CRT display 1/10, left and right one percent reflective TFT-LCD even only CRT, save a lot of energy and TFT-LCD products; specification, size series, variety, flexible and easy to use, maintenance, update, easy to upgrade, long service life and many other features. Display range from 1 inches to 40 inches display all application range and large projection plane is full size display terminal; display quality from the most simple monochromatic character graphics to high resolution, high color fidelity, high brightness, high contrast, high response speed of the video display of various specifications; display has a direct type of projection type, perspective, also reflection type.
(2) good environmental protection
No radiation, no flicker, no harm to the health of users. In particular, the emergence of TFT-LCD electronic books, will bring the human paperless office, paperless printing era, lead to human learning, communication and record of civilization revolution.
(3) wide scope of application
It can be used normally in the temperature range from -20 DEG C to +50 DEG C, and the working temperature of TFT-LCD can be reduced to 80 degrees below zero. The utility model not only can be used as a mobile terminal display, but also can be used as a large screen projection tv.
(4) a high degree of automation in manufacturing technology
Large scale industrial production characteristics. TFT-LCD industry mature technology, large-scale production of finished product rate of 90% or more.
(5) TFT-LCD is easy to integrate and update
It is the perfect combination of large scale semiconductor integrated circuit technology and light source technology. At present, there are amorphous, polycrystalline and monocrystalline silicon TFT-LCD, there will be other materials in the future TFT, both the glass substrate and plastic substrate.
