Image display device

摘要

An image display device includes an image display panel including a plurality of pixels 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 to the image display panel, 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 each pixel includes first to fourth subpixels, and the data voltage in the 2D image format is applied to the first to third subpixels and a luminance compensation voltage is applied to the fourth subpixel in the 2D mode, while the data voltage in the 3D image format is applied to the first to third subpixels and a dark gray voltage is applied to the fourth subpixel in the 3D mode.

1. An image display device, comprising:
an image display panel including a plurality of pixels 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 to the image display panel; 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 each pixel includes first to fourth subpixels, which are disposed in two parallel lines, the fourth subpixel being disposed in a line different from a line in which the first to third subpixels are disposed, and wherein the data voltage in the 2D image format is applied to the first to third subpixels and a luminance compensation voltage is applied to the fourth subpixel in the 2D mode, while the data voltage in the 3D image format is applied to the first to third subpixels and a dark gray voltage is applied to the fourth subpixel in the 3D mode.
