20110249223 | METHOD OF MANUFACTURING POLARIZING PLATE, POLARIZING PLATE MANUFACTURED BY THE SAME, AND LIQUID CRYSTAL DISPLAY HAVING THE POLARIZING PLATE - A method of manufacturing a polarizing plate includes fabricating a base film, dyeing the base film by using iodine, stretching the base film to form a polarizing film, firstly drying the polarizing film at a first temperature, and secondly drying the polarizing film while sequentially increasing a temperature from the first temperature to a second temperature higher than the first temperature. The polarizing plate and a liquid crystal display including the same are manufactured through the above method. | 10-13-2011 |
20120062822 | POLARIZING PLATE WITH A PHASE COMPENSATION FILM AND LIQUID CRYSTAL DISPLAY HAVING SAME - A liquid crystal display includes a first substrate having a first alignment layer, a second substrate having a second alignment layer, a liquid crystal layer having liquid crystal molecules operating in a twisted nematic (TN) mode, a first polarizing film, a second polarizing film, and a phase difference compensation film. The phase difference compensation film has a delay axis to compensate for an undesired phase difference imposed by the NT operating liquid crystal layer on light, traveling through the liquid crystal layer when an ideally fully untwisting electric field is applied to the liquid crystal layer, and the delay axis forms an acute angle with a rubbing direction of the second alignment layer. | 03-15-2012 |
20120242917 | SHUTTER PANEL AND DISPLAY DEVICE INCLUDING THE SAME - Provided is a shutter panel including a first substrate on which a plurality of electric field forming electrodes are parallel to each other, a second substrate opposed to the first substrate, and a liquid crystal layer disposed on the first and second substrates. Each of the electric field forming electrodes has both side surfaces facing the adjacent electric field forming electrodes, and both side surfaces are provided with protrusion parts protruding toward the adjacent electric field forming electrodes. | 09-27-2012 |
20120249939 | LIQUID CRYSTAL DISPLAY DEVICE WITH RETARDATION COMPENSATION - A liquid crystal device includes a twisted nematic liquid crystal panel and first and second retardation films disposed on the top and bottom sides of the twisted nematic liquid crystal panel. A retardation compensation range angle between an axis of the first retardation film and an axis of the second retardation film is smaller than a twist range angle between a first twist axis representing the average of twist angles of lower liquid crystals and a second twist axis representing the average of twist angles of upper liquid crystals in a plan view of the liquid crystal display device. | 10-04-2012 |
20130010359 | POLARIZATION SYSTEM AND THREE DIMENSIONAL IMAGE DISPLAY APPARATUS HAVING THE SAME - A polarization system including a first polarization film, a second polarization film, and a first retardation film disposed between the first and second polarization films. The first polarization film is disposed between a user and a light irradiator and the second polarization film is disposed between the first polarization film and the light irradiator. In addition, the first retardation film retards a phase of the light passing through the first polarization film. Thus, the polarization system allows the user to watch a 3D image without being related to the user's posture. A second retardation film may also be disposed between the first polarization film and the first retardation film. | 01-10-2013 |
20130050597 | THREE-DIMENSIONAL IMAGE DISPLAY APPARATUS - A three-dimensional image display apparatus includes a display panel configured to display an image and a shutter panel configured to separate the image into a left-eye image and a right-eye image. The shutter panel includes a first thin-film substrate disposed adjacent to the display panel, a second thin-film substrate facing the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The first substrate is disposed between the second substrate and the display panel. | 02-28-2013 |
20130141654 | POLARIZATION SYSTEM AND THREE-DIMENSIONAL IMAGE DISPLAY APPARATUS HAVING THE SAME - A 3D image display apparatus featuring a new polarization system is introduced which minimizes crosstalk between stereoimages. The polarization system includes a shutter panel that shifts the phase of an incident light, a polarizing film disposed between the shutter panel and an observer, a first retardation film disposed between the shutter panel and the polarizing film, a second retardation film disposed between the polarizing film and the first retardation film to correspond to the left eye of the observer, and a third retardation film disposed between the polarizing film and the first retardation film to correspond to the right eye of the observer. | 06-06-2013 |
