20110227886 | IMAGE DISPLAY DEVICE - An image display device includes a display panel that includes a plurality of subpixels and selectively displays the 2D image and the 3D image, and a patterned retarder that is positioned in front of the display panel and divides light from the display panel into light of a first polarization and light of a second polarization when the 3D image is displayed. Each subpixel includes a main subpixel including a first pixel electrode receiving a data voltage through a data line and a common electrode receiving a common voltage through a common line, and a subsidiary subpixel including a second pixel electrode receiving the data voltage through the data line, a common electrode positioned opposite the second pixel electrode, and a discharge thin film transistor (TFT) selectively connecting the second pixel electrode to the common electrode based on a displayed image. | 09-22-2011 |
20120154467 | IMAGE DISPLAY DEVICE AND DRIVING METHOD THEREOF - An image display device and a method of driving the same capable of improving visibility of both a 2D image and a 3D image and preventing a reduction in a luminance of the 2D image when implementing the 2D image are discussed. The image display device in one embodiment includes a display panel including a plurality of subpixels to selectively configure a 2D image and a 3D image, and a patterned retarder separating the light incident from the display panel into a first polarization component and a second polarization component, wherein the subpixel includes a main subpixel, a subsidiary subpixel and a control TFT for controlling a display gray level of the subsidiary subpixel. | 06-21-2012 |
20120268453 | IMAGE DISPLAY DEVICE AND METHOD FOR DRIVING THE SAME - An image display device and a method for driving the same are discussed. The image display device includes a display panel, which includes a subpixel disposed at a crossing between a pair of gate lines and a data line to selectively display a 2D image and a 3D image, a panel driver including a gate driver for driving the pair of gate lines and a data driver for driving the data line, a controller for differently controlling the panel driver in response to a mode selection signal, and a patterned retarder for dividing light from the display panel into first polarized light and second polarized light. | 10-25-2012 |
20120274748 | Stereoscopic Image Display Device and Method for Driving the Same - A stereoscopic image display device and a method for driving the stereoscopic image display device. The stereoscopic image display device divides pixels of a display panel into first sub-divided pixels and second sub-divided pixels. The second sub-divided pixels are controlled to function as an active black stripe during a 3D mode to enhance the quality of a 3D mode. However, the second sub-divided pixels are controlled to display a 2D image during a 2D mode to prevent the reduction of luminance in the 2D mode. | 11-01-2012 |
20130009941 | IMAGE DISPLAY DEVICE - An image display device includes a display panel which includes a plurality of pixels and operates in a 2D mode and a 3D mode, a patterned retarder for dividing light from the display panel into first polarized light and second polarized light, and a control voltage generator which generates a first DC control voltage of an off-level and a second DC control voltage of a slight-on level, which is higher than the off-level and is lower than a full-on level, and selectively outputs the first DC control voltage and the second DC control voltage depending on a driving mode. Each of the plurality of pixels includes an upper display unit and a lower display unit, which are vertically disposed in a mirror form. | 01-10-2013 |
