Abstract:
A transmissive color liquid crystal display comprising:a first liquid crystal section for presenting color images; a light-guiding element situated behind the first liquid crystal section for orienting rays toward the first liquid crystal section; a second liquid crystal section including a plurality of zones capable of transmitting wavelength bands of external rays, respectively, the zones being selectively activated for introducing colored external rays through respective zones to the light-guiding element; a first liquid crystal driver for controlling the first liquid crystal section, color-component data extracted from full color image data being input into the first liquid crystal driver in a time-division manner, the first liquid crystal driver activating and deactivating pixels on the first liquid crystal section for presenting images on the first liquid crystal display section on the basis of the color-component data in time division manner; and a second liquid crystal driver for controlling the second liquid crystal section, the second liquid crystal driver selectively activating the zones in the second liquid crystal section in time division manner for introducing colored external rays of which wavelength bands correspond to the color-component data through the zone to the light-guiding element for irradiating the images on the first liquid crystal section with the colored external rays in time division manner.
