Abstract: A display filter for a Liquid Crystal Display (LCD) having an anti-fog function includes a transparent support arranged in front of the display module and an anti-fog layer stacked in the rear of the transparent support to face the display module. The anti-fog layer prevents the display filter from fogging up.

Abstract: An optical member of an optical filter provided for a display device includes a colorant which can selectively absorb light with a predetermined wavelength. The optical member satisfies a following expression: 0??E*=?{square root over (?a*2+?b*2)}<5, where ?E* indicates the difference between reflected color and transmitted color under D65 standard light source. a* and b* correspond to achromatic colors satisfying following expressions: ?2.0?a*?2.0, and ?2.0?b*?2.0. An optical member of an optical filter provided for a display device includes a colorant which can selectively absorb light with a predetermined wavelength. The colorant may be a non-fluorescent colorant. The colorant includes a color adjusting colorant and a neon-cutting colorant. An optical filter for a display device includes this optical member.

Abstract: The present invention relates to a system for measuring wrinkles on a web in an R2R process. The system includes a laser generation device (100) for projecting a laser beam, emitted in a linear shape, onto a surface of a web (200), which is stopped or moving. A camera (300) captures a band of light, formed when the laser beam generated by the laser generation device (100) is projected onto the surface of the web (200), and transmitting image data of the captured light band. A measurement device (400) calculates coordinates of an arbitrary location on the web (200) on a basis of the image data transmitted from the camera (300), processes an image of the light band on a basis of the calculated coordinates, and displays the processed image. Accordingly, the results of reliable wrinkle measurement are provided for a web in an R2R process.

Abstract: A touch input detecting display filter includes a layered body and a vibration detector. The layered body includes a base substrate disposed in front of a display panel, and an optical filter part having an anti-reflecting film layered on the base substrate. The vibration detector is disposed on the layered body. When an object gets in touch with the layered body, the vibration detector detects vibration generated from a touch location of the layered body.

Abstract: 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.

Abstract: 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.

Abstract: An optical filter for a display device placed in front of a display panel 1000 of the display device includes a first layer 310 which is formed at a first area A1 and has a first light blocking ratio. The amount of light transmitted through the first area A1 is smaller than the amount of light transmitted through an adjacent area to the first area A1 such that the first area A1 becomes distinguished to form a dark mark or the adjacent area becomes distinguished to form a bright mark. The optical filter further includes a second layer 320 which is formed at a second area A2 and has a second light blocking ratio lower than the first light blocking ratio. The amount of light transmitted through the first area A1 is smaller than the amount of light transmitted through the second area A2 such that the first area A1 becomes distinguished to form the dark mark or the second area becomes distinguished to form a bright mark.
