technology whenver low power consumtion and compact size are critical.
LCD DISPLAY Liquid crystal
(KLC) is c sbstance that has both a liquid form and acrystal molecular
structure.LCD DISPLAY
The ro-shaped molecules are normally in a parallel arry, and an electric
field can be used to control the molecules. Most LCDs today use a type
of liquid crystal called ted nematic (TN) . LCDs consist of two pieces
of glass with transparent electrodes printed on the internal surfaces.
An alignment layer on each glass surfa LCD
DISPLAY used to twist the liquid crystal mterial in a helical or
LCD DISPLAY "twisted"
pattern. Polarizers are used on the outside front LCD
DISPLAY and rear surfaces. When the LCd is "off", no voltage
is applied to the LCD DISPLAY
eletrodes, and light passes throuh the LCD.

When
it's "on", voltage is applied and the LC LCD
DISPLAY molecules align themselves in the direction of the electric
field. This causes the light to be out of phase with the polarizers
and to be COG LCD MODULE blocked, creating a dark area on the LCD. By
selectively applying voltage to the electrodes, a variety of patterns
can be achieved. Many advances in TN LCDs have been produced. Super
twisted nematic (STN) LC material offers a higher twist LCD
DISPLAY angle (240 vs. 90) that provides higher contrast and a better
viewing angle. However, one negative feature is the birefringence effect,
which COG DISPLAY MODULE shifts the background color to yellow-green
and the character color to blue. This background color can be changed
to a gray by using a special filter. The most recent advance has been
the introduction of film super twisted nematic (FSTN) displays. This
adds a retardation film to the COG LCD
DISPLAY STN display that compensates for the color added by the
birefringence effect. This allows a black and white display to be produced.
LCD
DISPLAY Because of the added filtering, FSTN displays look
best when used with a COG DISPLAY MODULE backlight.
