LIQUID CRYSTAL DISPLAY PANEL [6 records]

Record 1 2012-08-15

English

Subject field(s)
  • Computers and Calculators
CONT

Panel PCs are available in a range of different sizes, computing performance and styles to suit a wide variety of applications. Typical applications include machine control (HMI), point of information kiosks (POI), point of sale (POS) and mobile computing in commercial vehicles, railway and marine use.

CONT

An all-in-one LCD PC refers to a computer that is contained within a Liquid Crystal Display(LCD) monitor. This is sometimes referred to as a Panel PC. The computer components are housed inside the monitor, and the media drive and ports are accessible along the sides of the monitor.

Subject field(s)
  • Photoelectricity and Electron Optics
  • Physics
  • Semiconductors (Electronics)
CONT

Twisted nematic : Cigar-like organic molecules form long helical chains when those along one face of the panel are oriented in one direction and those along the other face are oriented at right angles. A polarizing plate allows only ambient light polarized in one direction to pass through. This light is twisted 90 degrees by the helices. A second polarizer on the opposite face, polarized in the same direction as the first one, will block the light, creating a dark display. An applied voltage untwists the helix at a crosspoint, allowing light through and making a bright spot. A plate polarized at right angles will produce a bright display that goes dark at points where voltage is applied. Twisted nematic liquid crystal display(LCD).

CONT

Prenons l'exemple de l'effet qui est utilisé dans tous les dispositifs à cristaux liquides actuellement sur le marché : les nématiques en hélice [...]. La couche de cristal liquide nématique dont toutes les molécules sont parallèles est insérée entre deux plaques de verre distantes d'une dizaine de microns, avec des électrodes sur les faces internes. Au départ, les molécules sont parallèles aux plaques, mais par un traitement adéquat des lames on distord l'arrangement des molécules qui se placent en hélice. On place sur les faces externes des plaques deux polariseurs de lumière croisée qui ne devraient pas laisser passer de lumière. Mais grâce à l'anisotropie optique des molécules, l'hélice fait tourner de 90 degrés le plan de polarisation de la lumière qui la traverse. Ainsi, tant que l'hélice existe, la lumière passe. Là où on la détruit, ce qui se fait très simplement en appliquant une tension de quelques volts qui oriente les molécules perpendiculairement aux plaques, le dispositif devient noir.

Record 4 2004-09-07

English

Subject field(s)
  • Computer Display Technology
DEF

A passive matrix LCD [liquid crystal display] technology where two separate LCD plates are combined to form a single panel for improved image quality and contrast.

CONT

PM [passive matrix] LCDs come in several types including supertwisted nematic, double supertwisted nematic and triple supertwisted nematic. The original PM LCDs had a very limited viewing angle and poor contrast. Super and double supertwisted nematic designs provide an increased viewing angle and better contrast.

Subject field(s)
  • Air Navigation Aids
  • Aircraft Piloting and Navigation
OBS

The Electronic Flight Display System(EFDS) is an updated version of the Flight Display System(FDS). It is defined as the flight instrument, associated controls, and its interface to the aircraft, and is designed to provide the pilot, co-pilot, or Navigation/Communication(NAV/COMM) Officer with a comprehensive, unambiguous presentation of navigation information adequate for both worldwide tactical and non-tactical navigation. The display unit uses a flat panel domestic Active Matrix Liquid Crystal Display(AMLCD). The FDS functionally replaces the P-3 electro-mechanical Horizontal Situation Indicator(ID-1540/A), electro-mechanical Flight Director Indicators(FDI)(ID-1556), selected functions of the Navigation Availability Advisory Lights, and integrates GPS navigation with the flight instruments. Additional information such as navigational aid waypoint locations, GPS annunciation, and FDS status pages are also displayed.
