| 20100265435 | DISPLAY APPARATUS HAVING VARIABLE DIFFUSER FILM - In a display apparatus according to an embodiment, a variable diffuser film is disposed between a backlight unit generating light and a display panel displaying an image. The variable diffuser film transmits or scatters the light from the backlight unit in response to an electrical signal to control a viewing angle. The variable diffuser film is disposed between the first and second transparent layers and includes a polymer layer in which liquid crystal molecules transmitting or scattering the light according to the electrical signal are dispersed. The polymer layer has a thickness of about 3 micrometers to about 15 micrometers, and the liquid crystal molecules have an anisotropic refractive index (Δn) of about 0.15 to about 0.25. In one aspect, the display apparatus may automatically switch a narrow viewing angle mode and a wide viewing angle mode, thereby reducing power consumption necessary to switch the narrow and wide viewing angle modes. | 10-21-2010 |
| 20100315576 | LIQUID CRYSTAL DISPLAY AND METHOD OF MANUFACTURING THE SAME - A liquid crystal display includes a light source, a liquid crystal display panel including a pixel having a plurality of a color sub-pixel, and a reflective polarizer disposed between the light source and the liquid crystal display panel to transmit or reflect a light according to a direction in which the light vibrates. The reflective polarizer includes a reflective polarizing layer including a plurality of microfibers which each extend in a same direction with respect to each other, and a protective layer overlapping the reflective polarizing layer. A thickness of the reflective polarizing layer is a function of a pixel size. | 12-16-2010 |
| 20110038139 | OPTICAL FILM WITH REDUCED DISTORTION, METHOD OF MANUFACTURING THE SAME, AND DISPLAY APPARATUS HAVING THE SAME - An optical film includes a first base film having a first effective elongation axis that is skewed relative to a first reference line. The optical film further has a second base film having a second effective elongation axis that is opposingly skewed relative to the first reference line. Deformations are offset from each other when the deformations occur in the first and second base films in the directions of the first and second elongation axes due to variation of external temperature and humidity, thereby preventing the first and second base films from being excessively deformed. | 02-17-2011 |
| 20110110104 | OPTICAL PLATE AND METHOD OF MANUFACTURING THE SAME - An optical plate includes a first optical sheet, a reflective layer, and a second optical sheet. The first optical sheet includes first patterns protruding from a front surface. At least a portion of the first patterns includes a top surface parallel to the front surface. The reflective layer is provided on the top surface. A second optical sheet includes a rear surface making contact with the reflective layer. The optical plate is manufactured by forming the first optical sheet including the first patterns protruding from the front surface, forming the second optical sheet including the reflective layer and an adhesion layer, and bonding the first optical sheet with the second optical sheet such that at least the portion of the first patterns makes contact with the reflective layer. | 05-12-2011 |
| 20110157913 | LIGHT GUIDE PLATE, DISPLAY APPARATUS HAVING THE SAME, AND METHOD OF MANUFACTURING THE SAME - A light guide plate includes an incident surface receiving incident light from a light source, an exit section that outputs exit light having a light distribution different from a light distribution of the incident light and a reflective section opposite to the exit section. A plurality of first patterns are formed on the exit section while being arranged in a first direction of the exit section to distribute the exit light with maximum brightness in a direction perpendicular to the exit section. A plurality of second patterns are formed on the reflective section to scatter the incident light. | 06-30-2011 |
