In terms of performance, TFD both the TFT LCD liquid crystal screen and the advantages of the lcd display screen, TFD LCD is higher than the STN LCD screen brightness, and color is more bright-coloured, more power saving than TFT LCD screen at the same time, but in the color and brightness is worse than TFT LCD.
As TFT technology maturity in the COG LCD Display early ninety s, color LCD flat panel display is developing rapidly, less than 10 years, rapid growth TFT - LCD display for the mainstream, and it has the advantage of this is inseparable. The main features are:
(1) use good features: low voltage application, low driving voltage, congealing used to improve security and reliability; Flat, thin, save a large amount of raw materials and the use of space; Low power consumption, its power consumption is about one over ten of the CRT display, reflection type TFT - only about one percent of the Character LCD Modules lcd display and even save a large amount of energy; TFT - LCD products and specifications, size series, species diversity, convenient and flexible to operate, easy to maintenance, updates, upgrades, long service life and many other features. Display range covered the range from 1 inch to 40 inches all the display and the application scope of the projection plane, is a full size display terminal; Display quality from the simplest monochromatic character graphics to high resolution, high color fidelity, high brightness, high contrast, high response speed of various types of video display; Display mode has a look, projection, type of perspective, there is also a reflection.
A liquid crystal panel section of the module (LCM): panel process can be divided into three stages, first semiconductor processes preceding (array), that is, the transistor is a thin film layer on the glass substrate made, compared with the middle of the liquid crystal filling assembly process (cell), that is, the color filter layer of glass and glass film transistors, together, poured into a liquid crystal intermediate.
