Abstract:
1. A method of displaying a multi-mode stereoscopic image, comprising the steps of: aligning a display unit with a variable color barrier, the display unit having first pixels and second pixels displaying mixed image signals, each of the first pixels having at least one sub-pixel cell coded with a first color used for creating a left-eye picture and at least one other sub-pixel cell each coded with a color different from the first color and used for creating a right-eye picture and each of the second pixels having at least one sub-pixel cell coded with the first color used for creating the right-eye picture and at least one other sub-pixel cell each coded with the color different from the first color and used for creating the left-eye picture, the variable color barrier unit having first and second variable filters adjacent to and alternated with each other, wherein each of said first and second variable filters is overlapped with a portion of said first pixels and a portion of said second pixels such that all sub-pixel cells of each of the first pixels are aligned to a left-eye of an observer through at least one first variable filter and aligned to a right-eye of the observer through at least one second variable filter and all sub-pixel cells of each of the second pixels are aligned to the right-eye of the observer through at least one first variable filter and aligned to the left-eye of the observer through at least one second variable filter; displaying video signals obtained by photographing an object at different angles on the display unit; generating a mode signal for selecting between a stereoscopic mode and a plane mode; applying a first voltage to the first variable filters such that the first variable filters transmit a light of the first color while shutting off light of other colors and simultaneously applying a second voltage different from the first voltage to the second variable filters such that the second variable filters transmit the light of said other colors while shutting off the light of said first color when said stereoscopic mode is selected; and applying a third voltage different from both the first and second voltages to both of said first and second variable filters such that both the first and second variable filters transmit light of all colors when said plane mode is selected.
