What does F Stn mean?
(Film Compensated STN) A passive matrix LCD technology that uses a thin film optical filter layer between the STN display and front polarizer to change the default colors from blue on yellow-green to black on silver-gray.
How does liquid crystal display work?
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome.
What is twisted nematic display?
A twisted nematic (TN) display is a common type of liquid-crystal display ( LCD ) that consists of a substance called a nematic liquid crystal that is confined between two plates of polarized glass.
What is MVA panel?
MVA ( multidomain vertical alignment) technology is a type of VA technology. It was developed in 1996 by the Fujitsu company. In MVA displays, the starting direction of the LC molecules’ switching behavior is defined in advance by protrusions.
What is TFT and IPS display?
TFT, which stands for Thin Film Transistor, is an LCD display variant built and marketed for enhanced color, as well as contrast and black levels. IPS further improves display technology by providing better color reproduction and a wider, more accurate viewing angle.
Which liquid is used in LCD?
LCDs utilize either nematic or smectic liquid crystals. The molecules of nematic liquid crystals align themselves with their axes in parallel, as shown in the figure.
Why is it called liquid crystal display?
In the state in which molecules are in a uniform direction, they also have refractive indices, dielectric constants and other physical characteristics similar to those of crystals, depending on their direction, even though they are liquid. This is why they are called liquid crystal.
What is STN LCD and TN LCD?
What is STN LCD? STN lcd is super-twisted nematic lcd display, it is a type of monochrome lcd display, it is also passive liquid crystal display (LCD). compare to TN lcd, STN LCD twist angle is 240 degree, instead of 90 degree of TN LCD, so we call it STN LCD.
What is an FSTN LCD display?
FSTN LCD (Film compensated Super Twisted Nematic) FSTN LCD monochrome displays contain a retardation film applied to the STN display to produce a black and white display. This produces a higher contrast and wider viewing angle then STN or TN.
What are the different sizes of LCD displays?
Character LCD module (aka alphanumeric LCD display) The majority of character LCD modules listed below are STN 8 x 1 LCD Display, 8 x 2 LCD Display, 16 x 1 LCD Display, 16 x 2 LCD Display, 16 x 4 LCD Display, 20 x 2 LCD Display, 20 x 4 LCD Display, 24 x 2 LCD Display, 40 x 1 LCD Display, 40 x 2 LCD Display, 40 x 4 LCD Display.
