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 |

20090301772 | FILTER AND DISPLAY DEVICE HAVING THE SAME - A filter for a display device is provided which includes a base substrate, an electromagnetic shielding layer formed on one surface of the base substrate to block electromagnetic waves, and an electrode formed along at least two sides among four sides of the base substrate to earth the electromagnetic shielding layer, thereby reducing the manufacturing costs while maintaining the capability of blocking electromagnetic waves. | 12-10-2009 |
20100328763 | OPTICAL FILTER FOR DISPLAY DEVICE - An optical filter for a display device can be provided with excellent fracture strength without using heat-treated tempered glass. The optical filter is used in the display device having a display module therein and is disposed in front of the display module. The optical filter includes an annealed glass substrate, an optical film laminated on the surface of one side of the annealed glass substrate, and a protective layer formed on the surface of the other side of the annealed glass substrate. The protective layer serves to prevent a substance from being eluted from inside the annealed glass substrate. | 12-30-2010 |
20100328797 | DISPLAY FILTER - A display filter includes a base substrate disposed in front of a display module, an optical film laminated on the surface of the base substrate that faces a user, and a hard coating layer formed on the surface of the base substrate that faces the display module. The hard coating layer prevents the base substrate from being deformed. | 12-30-2010 |
20110007398 | DISPLAY FILTER AND PROTECTIVE CASE HAVING GRADATION - A display filter having a gradation, in use for a display device has a display module therein. The display filter includes a base substrate; and a light blocking section having a light blocking material formed on a periphery area of the base substrate to define an effective image-displaying area of the base substrate. The light blocking material blocks light, and at least a portion of the light blocking section becomes gradually darker in a predetermined direction. | 01-13-2011 |
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 |
