7 Inch Standard TFT LCD Flat And Thin, Saving A Lot Of Raw Materials And Use Space Nov 03, 2017

TFT (Thin Film transistor) LCD is a thin film field effect transistor LCD, which is one of the active matrix type liquid crystal display (AM-LCD). LCD flat panel display, especially 7 Inch Standard TFT LCD, is currently the only in the brightness, contrast, power consumption, life, volume and weight of comprehensive performance on the overall catch up with and exceed the CRT display devices, it has excellent performance, large-scale production characteristics, high degree of automation, low cost of raw materials, development space, Will quickly become the mainstream product of the new century, is the 21st century global economic growth a bright spot.

Unlike TN technology, the TFT display uses a "back-through" mode of illumination-the imaginary light source path is not from top to bottom as tn liquid crystals, but from the bottom up. The practice is to set a special light tube on the back of the liquid crystal, and the light shines through the lower side plate. Since the electrodes of the upper and lower interlayer are changed into FET electrodes and a common ohmic electrode, the performance of the liquid crystal molecule will change when the FET electrode is in flux, and the response time can be increased to around 80ms by shading and light transmission. Because of its higher contrast than TN-LCD and richer color, screen update frequency is faster, so TFT commonly known as "True Color."

The main feature of 7 Inch Standard TFT LCD, compared with DSTN, is to configure a semiconductor switching device for each pixel. Because each pixel can be directly controlled by a point pulse. Thus each node is relatively independent and can be continuously controlled. Such a design method not only enhances the response speed of the display, but also can accurately control the display of gray, which is more vivid TFT color than dstn reasons.

With the development of TFT technology in the early 90, the color LCD flat panel monitor developed rapidly, and in less than 10 time, 7 Inch Standard TFT LCD rapidly grew into a mainstream display, which was inseparable from its advantages. The main features are:

(1) Good use of features

Low-voltage applications, low drive voltage, solid use of safety and reliability improvement; flat, and thin, save a lot of raw materials and use of space; low power consumption, it consumes about one-tenth of CRT display, reflective 7 Inch Standard TFT LCD even only about 1% of CRT, save a lot of energy 7 Inch Standard TFT LCD products also have specifications model, size serialization, variety, easy to use, flexible maintenance, update, upgrade easy, long service life and many other characteristics. The display range covers the application range of all monitors from 1 inches to 40 inches and the projection large plane, full-size display terminals; display quality from the simplest monochrome character graphics to high-resolution, high color fidelity, high brightness, high contrast, high response speed of various specifications models of video display The display mode has the direct view type, the projection type, the perspective type, also has the reflection type.

(2) Good environmental characteristics

No radiation, no flicker, no harm to the health of users. In particular, the advent of 7 Inch Standard TFT LCD electronic books and periodicals will bring people into paperless office, paperless printing era, triggering a revolution in human learning, dissemination and recording of civilized ways.

(3) wide scope of application

From 20 ℃ to +50℃ temperature range can be used normally, after temperature hardening treatment of 7 Inch Standard TFT LCD low-temperature operating temperature can reach 0-80℃. Both as a mobile terminal display, desktop terminal display, but also a large-screen projection TV, is a good performance of the full size video display terminal.

(4) high degree of automation in manufacturing technology

Large-scale industrial production characteristics good. 7 Inch Standard TFT LCD Industry mature technology, large-scale production rate of finished product reached more than 90%.

(5) 7 Inch Standard TFT LCD is easy to integrate and upgrade

is a large-scale semiconductor integrated circuit technology and the perfect combination of light source technology, continue to develop a great potential. At present, amorphous, polycrystalline and monocrystalline silicon 7 Inch Standard TFT LCD, there will be other materials in the future TFT, both glass substrates and plastic substrates.
