THREE DIMENSION IMAGE DISPLAY APPARATUS AND METHOD THEREOF

A 3D image display apparatus and a method thereof are provided to scan a left-eye image and a right-eye image alternately in the display of each image frame and open and close the left eye and right eye of shutter glasses synchronizing with the scanning of the images, thereby enabling a user to feel a 3D image. A 3D(Three-Dimensional) image display apparatus comprises a scanning display device and a shutter device(160). The scanning display device scans a one-dimensional linear image in a direction perpendicular to the one-dimensional linear image and displays a left-eye image and a right-eye image of a two-dimensional image. The shutter device opens a left-eye portion when the left-eye image is displayed and opens a right-eye portion when the right-eye image is displayed. The scanning display device comprises a light source(110), an optical modulator(120), a driving circuit(125), a scanner(130) and an image controller(150). The optical modulator outputs modulated light that the brightness of incident light from the light source is changed according to a driving signal. The driving circuit generates the driving signal corresponding to a received image control signal to output the generated driving signal. The scanner projects the modulated light on a position of a screen(140) corresponding to a received scanner control signal. The image controller receives image signals corresponding to the left-eye image and the right-eye image, converts the image signals into the image control signal, transmits the image control signal to the driving circuit, and transmits a light source control signal synchronized with the image control signal, a shutter control signal, and the scanner control signal to the light source, the shutter device and the scanner respectively.
