Abstract:
1. A stereoscopic image display device, comprising: a display panel that is provided with a pixel array; a rendering processing unit that performs rendering for odd left image data so as to correspond to odd numbered display lines of the pixel array and for even right image data so as to correspond to even display lines of the pixel array during an n-th frame period, and performs rendering for odd right image data so as to correspond to the odd display lines of the pixel array and for even left image data so as to correspond to the even numbered display lines of the pixel array during a (n+1)-th frame period; a patterned retarder including a first retarder that transmits light which is incident from the odd numbered display lines of the pixel array so as to be modulated into first circularly polarized light, and a second retarder that transmits light which is incident from the even numbered display lines of the pixel array so as to be modulated into second circularly polarized light; active retarder glasses including a first active retarder that transmits one of the first circularly polarized light and the second circularly polarized light from the patterned retarder, and a second active retarder that transmits the remaining one of the first circularly polarized light and the second circularly polarized light from the patterned retarder; and a control unit that generates a switchable control signal having a first logic value or a second logic value and controls phase delays in the first and second active retarders.
