The first polarization plate has a pair of second short ends longer than the first short ends, a pair of second long ends, and a first absorption axis. The angle a | 10-29-2015 |
| 20150378078 | Displays With Polarizer Layers for Electronic Devices - An electronic device may have a display. Inactive portions of the display may be masked using an opaque masking layer. An opening may be provided in the masking layer. A camera may receive light through the opening in the opaque masking layer. The display may include upper and lower polarizers, a color filter layer, and a thin-film transistor layer. The upper polarizer may have an unpolarized window aligned with the opening in the opaque masking layer for the camera, a logo, or another internal structure. The unpolarized window may be formed from openings in polarizer layers such as a polyvinyl alcohol layer and optical retarder layers. The openings may pass through all or less than all of the polarizer layers. The openings may be filled with transparent filler material. The polarizer may include a try-acetyl cellulose layer that continuously covers the opening in other polarizer layers. | 12-31-2015 |
| 20160037655 | DISPLAY DEVICE - A display device includes a display panel; an upper frame configured to cover an edge portion of an upper surface and side surfaces of the display panel; a pad between the display panel and the upper frame; and a film member between the pad and the display panel. | 02-04-2016 |
| 20160062016 | POLARIZING PLATE, COMPOSITION FOR PROTECTIVE LAYERS OF A POLARIZING PLATE, AND OPTICAL DISPLAY INCLUDING THE SAME - A composition for protective layers of a polarizing plate includes a photocurable monomer or oligomer having a glass transition temperature (Tg) of about 50° C. or greater, particles, a reactive monomer or oligomer, and an initiator. A polarizing plate includes a polarizer and a protective layer formed from the composition on one or both surfaces of the polarizer. The protective layer has a storage modulus at about 25° C. of greater than about 2000 MPa, as measured at a heating rate of 10° C./min, a temperature of −50° C. to 100° C., a frequency of 1 Hz, and a strain of 0.5%. An optical display includes the polarizing plate. | 03-03-2016 |
| 20160062182 | DISPLAY DEVICE - A display device may include a first substrate having a display area and a non-display area, a second substrate opposite the first substrate, a light shielding sealant on at least one side surface of the first and second substrates, and a first polarizer on at least one surface of the first and second substrates. The first polarizer may intersect an imaginary surface extending from the at least one side surface. | 03-03-2016 |
