Abstract

See full text

A personal liquid crystal image display includes a housing to be worn on a user's head, a light-transmission-type liquid crystal display panel for displaying video signals and a lens positioned between the display panel and a user's eye to enlarge the image. The housing may include earphones. The display and earphones are coupled to a tuner for receiving signal and driving the display and earphones. A portion of the drive circuit for driving the display may be disposed in the housing.
