Definition |
TFT * |
Thin film transistor
A transistor formed on a thin film on a
substrate such as glass. Used in the active
matrix of liquid crystal, etc., as a 3-pin
active element. |
Liquid crystal * |
·
A material that appears as a fluid, cloudy
liquid within a certain temperature range,
but at the same time exhibits
double-refractive characteristics unique to
solid optical anisotropic crystals.
·
A material that consists of cylindrical or
plate-shaped molecules and that has a
mesophase with a long-range order for at
least one molecule axis. |
Liquid crystal display module* |
A module with a liquid crystal panel
incorporating (at least) a driver and that
displays information using light modulation.
May also include components such as a
backlight and base. |
Polarizer * |
An optical material with a function that
enables the transmission of only a specific
polarized light element from the incident
light. |
Diffusing plate * |
An optical material used to scatter the
light from light source to enable even
irradiation on the display panel. |
Light guide plate * |
A structural component used to guide and
disperse the light from the light source. A
transparent flat plate with a dispersion
pattern on the back is usually used for
edge-light type backlights. |
Lens sheet (condenser) |
Condenses the light emitted from the light
guide plate and diffusing plate through an
arrangement of numerous minute prisms in
order to improve the luminance on the
display surface. |
Reflector * |
An optical material used to reflect and
effectively utilize the light from the
backlight. |
Liquid crystal display panel* |
A panel sandwiched between at least two
substrates and filled with a liquid crystal
substance at intervals of several
micrometers. The alignment of the liquid
crystal substance in this panel is
controlled by external signals and
information is displayed by modulating the
light. |
Backlight |
A light source system that irradiates the
display surface evenly from the back. |
