20090058250 | Filter for display apparatus - A filter for a display apparatus is placed in front of a display panel, wherein CIE chromaticity coordinates of the filter under a standard of a D65 light source have values of −2.0≦a*≦2.0 and −2.0≦b*≦2.0. The CIE chromaticity coordinates of the filter under the standard of the D65 light source have a value of 60≦L*≦80. The colorants include a first colorant absorbing 380 nm to 480 nm wavelength light, a second colorant absorbing 450 nm to 550 nm wavelength light, and a third colorant absorbing 560 nm to 620 nm wavelength light. The first to third colorants can be contained in at least one of a color compensating layer, a low-refraction layer having a refractive index of 1.5 or less, an external light shielding layer, a hard coating layer and an adhesive layer. | 03-05-2009 |
20090122238 | Protection Filter For Liquid Crystal Display - A protection filter for a liquid crystal display (LCD) includes a transparent substrate and a heat-blocking film comprising a metallic compound thin film and a transparent metallic thin film which are alternately formed on the transparent substrate. | 05-14-2009 |

20090273581 | DISPLAY FILTER AND DISPLAY DEVICE HAVING THE SAME - A display filter for a display device having a display panel includes a base substrate disposed in front of the display panel; an optical filter part layered based on the base substrate and comprising at least an anti-reflection layer; and a touch signal sensing part layered on the base substrate or the optical filter part and sensing a touch signal by a sensed object. An optical filter and a touch input means are combined together, and thereby the display filter can perform a touch input function as well as an optical filter function. | 11-05-2009 |
20090310212 | FILTER AND DISPLAY DEVICE HAVING THE SAME - A filter for a display device includes a base substrate, a shielding film formed based on a single transparent base layer, and an adhesive layer adhering the shielding film onto the base substrate. The shielding film which realizes diverse shielding functions in a single sheet is adhered onto the base substrate through a single process, which serves to improve productivity, reduce manufacturing cost, restrain the occurrence of Haze and improve visibility. | 12-17-2009 |
20110032622 | OPTICAL FILTER FOR DISPLAY DEVICE - An optical filter for a display device includes a base substrate, an EMI shielding coating formed directly on an upper surface of the base substrate to filter EMI, and a color control resin coating applied directly on a lower surface of the base substrate or an upper surface of the EMI shielding coating. Due to the EMI shielding coating and the color control resin coating formed directly on the base substrate, it is possible to simplify a manufacturing process, improve productivity, and reduce manufacturing costs. | 02-10-2011 |
20130149434 | METHOD OF CUTTING TEMPERED GLASS AND METHOD OF FABRICATING TOUCHSCREEN USING THE SAME - A method of cutting a piece of tempered glass in which the piece of tempered glass is cut after a thin film having a tensile stress is formed a method of fabricating a touchscreen using the same. The method includes a step of forming a thin film layer having a tensile stress on the piece of tempered glass and a step of cutting the piece of tempered glass. | 06-13-2013 |
20140154424 | ROLL-TO-ROLL SPUTTERING METHOD - A roll-to-roll sputtering method transports a flexible substrate wound on an unwinder roll to a depositing part, forms a deposited film on the flexible substrate, and winds the flexible substrate on a winder roll. The depositing part includes a first depositing part. The first depositing part includes a first sputtering part which deposits a first target material on one surface of the flexible substrate and a heater which is disposed at a side of the other surface of the flexible substrate to heat the flexible substrate. | 06-05-2014 |
20150013389 | Toughened Glass Fabrication Method And Toughened Glass Fabricated Thereby - A toughened glass fabrication method in which the productivity of a large toughened glass and the strength variation of the toughened glass can be improved and a toughened glass fabricated thereby. The toughened glass fabrication method includes the steps of mounting jigs on an upper surface and an undersurface of a raw glass such that an injection space through which a gel-type salt mixture is to be injected is defined between each of the jigs and the raw glass, injecting the gel-type salt mixture into the injection spaces, and heat-treating the raw glass on which the jigs are mounted. | 01-15-2015 |
