Reflective LCD

Overview

Reflective LCD technology is an important element in our recent research plans.

To familiarize people with the informationalized society, further progress is needed in making the display as "information interface." In particular, new display devices should have light weight, high resolution, full-color, and most importantly, "super low-power consumption," to meet the demand for free exchange of information at any time and at any place. By consuming less energy, such devices will incidentally contribute to preserving the global environment.

Term	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.
