20100045897 | CONDENSING FILM FOR LCD BACKLIGHT UNIT - There is provided a condensing film for an LCD backlight unit. The condensing film includes a base member unit; a condenser unit disposed in an upper surface of the base member unit and having unit lens groups sequentially arranged thereon, each of the unit lens group being composed of a combination of at least two lenses that are different in shape; and a reflector unit disposed in a lower surface of the base member unit and composed of an opening through which light passes and a reflective surface from which the light reflects. The condensing film configured thus may be useful to solve the problems regarding the viewing angle and the uniformity in brightness of a screen since the condensing film has a more moderate distribution of emitted light than the conventional condensing films. | 02-25-2010 |
20100232142 | Condensing film for LCD backlight unit and LCD backlight unit using the same - There is provided a condensing film for an LCD backlight unit. The condensing film including a film unit; a light outgoing unit formed in an upper surface of the film unit; and a light ingoing unit formed in a lower surface of the film unit, wherein a light diffuser is included inside the condensing film. The condensing film may be useful to widen a viewing angle and prevent the formation of hot bands by improving luminance distribution characteristics of light emitted from the condensing film since the condensing film includes a light diffuser capable of diffusing the light. | 09-16-2010 |
20100321787 | Optical Film And Manufacturing Process Thereof - There is provided an optical film for backlight units or illuminators. The optical film comprises a light-incident portion and a light exit portion. Here, the optical film is characterized in that it comprises a plurality of protrusions formed on at least one of the light-incident portion and the light exit portion, wherein a plurality of the protrusions satisfies the requirements of the following Equation: 80×H | 12-23-2010 |
20130121022 | OPTICAL SHEET HAVING IMPROVED DURABILITY, AND BACKLIGHT UNIT COMPRISING SAME - A durability-enhanced optical sheet and an edge-type backlight unit having the optical sheet. The edge-type backlight unit includes a light source unit that includes a plurality of light sources, a light guide unit that is disposed adjacently to the light source unit and controls a path of light generated from the light source unit, a diffusion sheet disposed on the light guide plate, and an optical sheet that is disposed on the diffusion sheet and includes a lens unit and a non-lens unit, wherein the non-lens unit includes a first base unit, a second base unit, and a bonding layer for bonding the first and second base units. The optical sheet includes two base unit layers, and thus, sheet waves that can be caused due to heat can be prevented, modulus can be increased, and durability of the optical sheet can be enhanced. | 05-16-2013 |
20140313697 | MICRO LENS ARRAY SHEET AND BACKLIGHT UNIT COMPRISING THE SAME - There are provided a micro lens array (MLA) sheet including a plurality of lens units two-dimensionally arranged thereon, wherein each lens unit has a conic lens shape of which a vertical cross-section taken in a lens center is represented by Expression 1, and a backlight unit including the same. | 10-23-2014 |
20150260893 | METHOD OF MANUFACTURING DOUBLE-SIDED POLARIZING PLATE AND DOUBLE-SIDED POLARIZING PLATE MANUFACTURED USING THE SAME - A method of manufacturing a double-sided polarizing plate and a double-sided polarizing plate manufactured using the same are provided. The method of manufacturing a double-sided polarizing plate includes attaching transparent films to both surfaces of a polarizer via adhesive layers; irradiating the adhesive layers with active energy rays in an amount of light of 200 mJ/cm | 09-17-2015 |
