The stereoscopic image display apparatus having patterned retarder includes an array substrate, a polarized plate and a film-type patterned retarder (FPR). The array substrate includes a gate driver, a source driver, a plurality of pixel units and a plurality of transistor control modules. Each pixel unit corresponds to first scan line, second scan line and third scan line respectively. Each of the pixel units includes at least two data lines wherein the first scan line, the second scan line and the third scan line are insulatedly interlaced with the at least two data lines. A polarized plate receives a light beam passing through the array substrate to generate a linear polarized light beam. A film-type patterned retarder disposed on the polarized plate receives the light beam passing through the array substrate for generating the three-dimensional image on the polarized glasses. | 12-19-2013 |
20150015615 | LCD AND METHOD FOR DRIVING THE SAME - An LCD includes multiple pixel units and a processing unit. The pixel units are used for displaying 2D or 3D images upon receiving 2D image signals or 3D image signals. The processing unit is used for outputting the plurality of 2D/3D image signals upon receiving a 2D/3D image enbaling signal. Each pixel unit includes a first pixel electrode, a second pixel electrode, and a third pixel electrode. The first pixel electrode is used for receiving a first voltage signal in response to the 2D or 3D image enbaling signal. The second pixel electrode is used for receiving the first voltage signal in response to the 2D image enbaling signal or for receiving a second voltage signal when corresponding to the 3D image enbaling signal. The third pixel electrode is used for receiving the plurality of 2D or 3D image signals. The first, second, and third pixel electrodes are disposed on the same substrate and are not connected to one another. | 01-15-2015 |
20150085000 | METHOD FOR DRIVING DISPLAY DEVICE - Disclosed is a method for driving a display device. The display device comprises scanning lines, data lines, pixels, a first source driving circuit, and a second source driving circuit. The scanning lines are sequentially located in a first region, an intermediate region, and a second region. Each data line is divided into two electrically disconnected lines. The method comprises: turning on one scanning line in the first region and one scanning line in the second region simultaneously; the first and second source driving circuits providing data for each pixel electrically connected to the turn-on scanning lines in the first and second regions; turning on one scanning line in the intermediate region; and providing data by the first or second source driving circuits according to a position in which each data line is divided into the two electrically disconnected lines. | 03-26-2015 |
