Patent ID: 8633974

Claim:
An image display device, comprising: an image display panel configured to display a 2D image or a 3D image; a driving circuit configured to apply a data voltage in a 2D image format or a data voltage in a 3D image format; a controller configured to control the driving circuit in a 2D mode for displaying the 2D image or in a 3D mode for displaying the 3D image; and a patterned retarder configured to convert light from the image display panel to alternately have a first polarization and a second polarization; wherein R, G, and B subpixels of the image display panel each comprises first and second fine subpixels, wherein the data voltage in the 2D data format is applied to the first fine subpixel and a luminance compensation voltage is applied to the second fine subpixel in the 2D mode, wherein the data voltage in the 3D data format is applied to the first fine subpixel and a dark gray voltage is applied to the second fine subpixel in the 3D mode, wherein the luminance compensation voltage for each second fine subpixel is an average luminance value of the data voltages in the 2D image format applied to the R, G, and B subpixels.
