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 ds fthe 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 module manufacturer 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 d fdf dcolor to yellow-green and the character color
to blue. This background color can be df fchanged 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 module manufacturer Because
of the added filtering, FSTN displays look best when used with a COG DISPLAY
MODULE backlight.
