Twisted Nematic A type of display where the liquid crystal fluid rotates

 the plane of polarization 90^o.

Translucent material used for light diffusion placed between backlight lightin

g sources and the back side of an LCD. This material will create a more uniform 

 backlight for an LCD from several unique sources of light.

The process of applying opaque, colored inks to the display to provide colors,

 or highlight certain areas of annunciators

The preferred angle of viewing a display, usually described in comparison to a

 clock face, i.e. 12 o´clock for above the normal, or 6 o´clock for below the 

 normal

The common electrode connection. There can be multiple backplanes in 

a multiplexed display.

The area of a display which is visible through a bezel or cut-out in an instrument

. This area is made up of the "Active Area" and the boarder around the active area

STN Technology with the addition of a retardation film to the display that

 compensates for the color added by the birefringence effect. This allows a

 black and white display to be produced and provides for a higher contrast 

and wider viewing angle.

Method of manufacturing whereby displays are arranged in rows and column

s on a large laminate, and separated after they are filled with LCD fluid

Color STN Technology. Each pixel of a CSTN display is actually 3 separate

 colored pixels of Red / Green / Blue. Each of those colors are controlled

 individually by the graphic controller chip. So in actually; a 320 by 240 pixel 

CSTN display actually contains 960 by 240 individually colored pixels

An LCD construction technique where the cell geometry is optimized for

 maximum contrast and viewing angle. The geometry is different for each LCD fluid

An active area within the display which can be turned on and off. This can

 be a single segment of a 7-segment character, an annunciator, or a pixel in 

a dot matrix array

A viewing mode which uses ambient or other front lighting to provide the

 illumination for the display.

A viewing mode which cannot use any type of front lighting to provide th

e illumination for the display, it therefore must use a backlight

A viewing mode which can use ambient light or backlighting to provide the

 illumination for the display

A type of display which uses fluids which "twist" greater than 90^o. An STN

 display has improved viewing angles and contrast at high multiplex rates

A thin flexible cable used to connect the LCD to the PC board which is bonde

d by heat cured adhesive at each end

A thin conductive material used to make connections between a 

LCD and a PC board

A stretched polymer which transmits light in only one axis. A typical displa

y has polarizers on the front and back.

A method of driving a display whereby multiple segments are driven fro

m the same edge connection

A method of driving a display whereby individual segments are driven from

 separate edge connections

A display which has a light background and darker active segments, i.e. black

 characters on a silver background.

A display which has a dark background and lighter active segments, i.e. clear

 characters on a black background
