1-3 Main component of LCD Display

LCD Shutter
Supplying voltage to the transparent electrodes between the pixel and common sides changes the
arrangement of liquid crystal. By assembling two polarized boards, the transfer of light from the backlight
can be controlled by the transparent ratio of the LCD Shutter.
Liquid Crystal
Liquid Crystal is a material whose state is between a solid and a liquid. It has both characteristics of
solids and liquids, and generally it is a white turbid liquid. Its molecules are normally arranged compara-
tively opaque and change to transparent with the application of voltage or heat.
Transparent Electrode (Film)
An LCD shutter is operated by supplying voltage derived from the video signal. Transparent film is used
for its electrode.
Alignment Film
This is a film for arranging liquid crystal molecules and is made of Polymid resin.
Polarized Board
The light with a specified direction passes through a polarized board.
Drive Transistor
The thin film transistor (TFT) is used to drive the LCD shutter of each pixel.
Color Filter
It is a filter with three colors (R, G, B) arranged for each pixel.
Backlight
Liquid crystal does not emit light. A light source is needed for display. The light source placed on the
reverse side of the LCD panel is called "Backlight."
