Default Which is a better display tech?


Ok Ppl,

Which is a better display tech?

CSTN or TFT

From wikipedia:

CSTN: http://en.wikipedia.org/wiki/Super-t...ematic_display

A super-twisted nematic display (STN) is a type of monochrome passive matrix liquid crystal display (LCD). STN displays provide more contrast than twisted nematic (TN) displays by twisting the molecules from 180 to 270 degrees. STN LCDs require less power and are less expensive to manufacture than TFT LCDs, another popular type of LCD that has largely superseded STN for mainstream laptops. However, STN displays typically suffer from lower image quality and slower response time than TFT displays. STN displays are used in some inexpensive mobile phones and informational screens of some digital products.

CSTN stands for color super-twist nematic, a color form of passive matrix LCD (Liquid Crystal Display) for electronic display screens originally developed by Sharp Electronics. The CSTN uses red, green and blue filters to display color. The original CSTN displays developed in the early 90s suffered from slow response times and ghosting (where text or graphic changes are blurred because the pixels cannot turn off and on fast enough). Recent advances in the technology, however, have made CSTN a viable alternative to active matrix displays. New CSTN displays offer 100ms response times (TFT 8ms), a 140 degree viewing angle and high-quality color rivaling TFT displays - all at about half the cost. A newer passive-matrix technology called High-Performance Addressing (HPA) offers even better response times and contrast than CSTN.

TFT: http://en.wikipedia.org/wiki/TFT_LCD

A thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin film transistor (TFT) technology to improve image quality. TFT LCD is one type of active matrix LCD, though it is usually synonymous with LCD. It is used in televisions, flat panel displays and projectors.

Reading this says that TFT are much better than CSTN.
