[0001] The present invention relates to a three-dimensional image display device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional image display apparatus, and more particularly, to a switchable three-dimensional image display apparatus including first through third red, green and blue sub-pixels arranged to prevent color separation and a driving method thereof.

The implementation technology of three-dimensional image that enables three-dimensional depth and three-dimensional feeling to be sensed from two-dimensional image is widely used in a wide range of fields such as display and the like, , And the technical ripple effect is expected to be more than HDTV (High Definition Television), which is currently in the spotlight.

The most important factor that human beings feel depth and stereoscopic effect is the binocular disparity due to the gap between the two eyes. In addition, there is a deep relationship with the psychological and memory factors. Therefore, A volumetric type, a holographic type, and a stereoscopic type based on whether a three-dimensional image can be provided to the user.

The volume expression method is a method for making the perspective of the depth direction to be perceived by the psychological factors and the suction effect. It is a three-dimensional computer graphic that displays the perspective method, overlapping, shading and contrast, So-called "IMAX" movies, which give rise to a phenomenon of optical illusion that is provided to a large screen and sucked into the space.

And, the three-dimensional representation method known as the most complete stereoscopic image realization technique can be represented by laser light reproduction holography or white light reproduction holography.

In addition, the three-dimensional representation method is a method of making a three-dimensional feeling using the physiological factors of both eyes. In the case where a plane-related image including parallax information is displayed on the left and right of a human being, The ability to generate spatial information before and after the display surface in order to feel a stereoscopic effect, i.e., stereography.

This stereoscopic effect expression system is called a multi-view display system. Depending on the position of actual stereoscopic effect generation, a spectacle system using special glasses on the observer side or a parallax barrier, a lenticular, or an integral system on the display surface side, And a non-eyeglass system using a lens array such as a lens array.

The principle of three-dimensional image realization of a stereoscopic 3D display device using a parallax barrier or a lens array is briefly described as follows. A stripe is provided between a display panel for simultaneously displaying left and right stereoscopic images, A slit and a barrier of the shape of a semicylindrical lenticular lens are arranged or a plurality of semicylindrical lenticular lenses are arranged so that an observer can feel the stereoscopic effect.

At this time, the width P of the left eye pixel L and the right eye pixel R formed on the display panel 20, the width M of the barrier 34 of the parallax barrier 30, The width Q of the slit 32, the width E between the left and right eyes, the distance S from the display panel 20 to the parallax barrier 30 and the distance S from the parallax barriers 30 to the viewer 40, (D) to the distance D has the following relationship.

M + Q = 2 / (1 / E + 1 / P)

D = SE / P

The width E between the left eye and the right eye of the human being is approximately 65 mm and the width E of the left eye pixel L and the right eye pixel R is calculated using the above relationship with the value of the width E between the left eye and the right eye Dimensional image can be displayed on the parallax barrier type three-dimensional image display device 10 by designing the width W of the slit 32, the width M of the barrier 34, and the width Q of the slit 32,
