The present invention provides a three-dimensional image display device for improving the visibility with prevention of moir&#xe9; phenomena. The display device includes an image panel having a pixel repeatedly arranged in a first direction. The pixel consists of k sub-pixels where k is natural number. The average of the center distances between adjacent sub-pixels in the first direction is P. The display also includes a barrier panel arranged before or behind the image panel, a first substrate and a second substrate facing each other. The barrier panel is arranged between the first and the second substrate. The display device further includes a plurality of walls extended in a second direction crossing the first direction arranged with an interval Pin the first direction, where m is a natural number but not a multiple of k, and P=mP.

Three-dimensional image display device

A system for controlling brightness flicker of a parallax barrier LCD having a wide viewing angle capable of minimizing brightness flicker by adjusting a permittivity curve depending on different times into a predetermined waveform when split barriers are on/off by movement of a viewer's viewing angle, and a method thereof. A method of controlling brightness flicker of a parallax barrier LCD having a wide viewing angle for controlling brightness of a display providing a stereoscopic image by acquiring a real-time image of a viewer, recognizing an image of the viewer and extracting locations and coordinates of eyes of the viewer, and controlling turn-on/off of split barrier electrodes.

System for controlling brightness flicker of parallax barrier LCD that has wide viewing angle and method thereof

Disclosed is a full color liquid crystal display, including a lower substrate and an upper substrate facing each other, partition spacers uniformly arranged between the lower substrate and the upper substrate to form a plurality of spaces while maintaining a cell gap between the lower substrate and the upper substrate, a lower transparent electrode and an upper transparent electrode respectively provided to the lower substrate and the upper substrate in the spaces defined by the partition spacers so as to face each other, subpixels having liquid crystals which are able to reflect or absorb respective specific light wavelengths and which are separately received in the spaces defined by the partition spacers, a plurality of such subpixels constituting a single pixel to exhibit full color.
