Method of displaying stereoscopic image and stereoscopic image display device for performing the same

A stereoscopic image display device comprising:

• a display panel comprising a plurality of pixels, the display panel temporally dividing at least two view images corresponding to at least two viewing spaces to display the temporally divided image on a display panel;
• an optical lens assembly comprising a spatial division lenticular lens part configured to convert the view image displayed on the display panel into N stereoscopic images in which directions of the view images are different from each other to emit the converted view image therefrom toward a viewing space corresponding to the view image displayed on the display panel, wherein, ‘N’ is a natural number of no less than two;
• a control part converting an image received during a frame interval period into the at least two view images;
• and
• a display driving part temporally dividing the frame interval period into at least two sub-frame interval periods to display the at least two view images on the display panel,
• wherein the display panel is configured to display a first view image thereon during a first sub-frame interval period of the frame interval period,
• wherein the spatial division lenticular lens part is configured to convert the first view image into N stereoscopic images in which directions thereof are different from each other,
• wherein the spatial division lenticular lens part is configured to refract the N stereoscopic images,
• wherein the spatial division lenticular lens part is configured to emit the refracted N-stereoscopic images therefrom toward a first viewing space corresponding to the first view image,
• wherein the display panel is configured to display a second view image thereon during a second sub-frame interval period of the frame interval period;
• wherein the spatial division lenticular lens part is configured to convert the second view image into N stereoscopic images in which directions thereof are different from each other,
• wherein the spatial division lenticular lens part is configured to emit the N stereoscopic images therefrom toward a second viewing space corresponding to the second view image without refracting the N stereoscopic images,
• wherein the spatial division lenticular lens part is configured to emit the N stereoscopic images toward the first and second viewing spaces, wherein in one of the first or second sub-frame interval periods the spatial division lenticular lens part is configured to refract the N stereoscopic images and emit the refracted N stereoscopic images therefrom toward one of the first or second viewing spaces and wherein in the other one of the first or second sub-frame interval periods the spatial division lenticular lens part is configured to emit the N stereoscopic images therefrom toward the other one of the first or second viewing spaces without refracting the N stereoscopic images.
