Forskellen på lcd og TFT

En TFT skærm er en underbetegnelse for en LCD skærm. TFT er den i øjeblikket bedste form for LCD skærm.

En 15\" LCD skærm svarer i synligt område ca. til en alm. 17\".

Først en definition:

Abbreviation of liquid crystal display, a type of display used in digital watches and many portable computers. LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light.

Monochrome LCD images usually appear as blue or dark gray images on top of a grayish-white background. Color LCD displays use two basic techniques for producing color: Passive matrix is the less expensive of the two technologies. The other technology, called thin film transistor (TFT) or active-matrix, produces color images that are as sharp as traditional CRT displays, but the technology is expensive. Recent passive-matrix displays using new CSTN and DSTN technologies produce sharp colors rivaling active-matrix displays.

Den ene type bygger på krystaller (passiv LCD), og den anden på en \"film\" der indeholder en masse små transistorer (aktiv).

Den aktive (altså TFT skærmen) giver et meget klarere og skarpere billede end den passive skærm. Prisen er dog også noget højere

blev du klogere?????

Ja tak. men

hvorfor er der så nogle der hedder tft lcd skærme?

det er det samme
