The present invention discloses a display including a display panel and a light redirecting film disposed on the viewing side of the display panel. The light redirecting film comprises a light redistribution layer, and a light guide layer disposed on the light redistribution layer. The light redistribution layer includes a plurality of strip-shaped micro prisms extending along a first direction and arranged at intervals and a plurality of diffraction gratings arranged at the bottom of the intervals between the adjacent strip-shaped micro prisms, wherein each of the strip-shaped micro prisms has at least one inclined light-guide surface, and the bottom of each interval has at least one set of diffraction gratings, and the light guide layer is in contact with the strip-shaped micro prisms and the diffraction gratings. The present light redirecting film is disposed on the viewing side of the display panel to decrease the light loss in the side viewing angle of the display, and homogenize the brightness distribution at different viewing angles thereof.

Display

The present invention discloses a light redirecting film, a polarizer with the light redirecting film, and a display comprising the polarizer. The light redirecting film includes a light redistribution layer, and a light guide layer disposed on the light redistribution layer. The light redistribution layer includes a plurality of strip-shaped micro prisms extending along a first direction and arranged at intervals and a plurality of diffraction gratings arranged at bottoms of the intervals between the adjacent strip-shaped micro prisms, wherein each of the strip-shaped micro prisms has at least one inclined light-guide surface, and the bottom of each interval has at least one set of diffraction gratings, and the light guide layer is in contact with the strip-shaped micro prisms and the diffraction gratings. The present light redirecting film is disposed on the viewing side of the display to decrease the light loss in the side viewing angle of the display, and homogenize the brightness distribution at different viewing angles thereof.

Light redirecting film, a polarizer and a display comprising the same

An optical film includes a first diffraction layer, a second diffraction layer, and a cover layer. The first diffraction layer includes a plurality of first diffraction gratings arranged in a direction on a surface thereof. The second diffraction layer is filled in the gap of the first diffraction gratings of the first diffraction layer and forms a plurality of second diffraction gratings arranged in a direction on the first diffraction layer, wherein the directions of the first diffraction gratings and the second diffraction gratings are parallel to each other. The cover layer fills and planarizes the second diffraction gratings of the second diffraction layer. The optical film can reduce the light leakage defect of a conventional liquid crystal display in a wide viewing angle and make the liquid crystal display have a uniform dark-state image and color image quality.

Optical film

An optical film includes a first diffraction layer, a second diffraction layer, and a cover layer. The first diffraction layer includes a plurality of first diffraction gratings arranged in the same direction on a surface thereof. The second diffraction layer includes a plurality of second diffraction gratings arranged in the same direction gap-filled the first diffraction gratings of the first diffraction layer, wherein the directions of the first diffraction gratings and the second diffraction gratings are parallel to each other. The cover layer is formed on the second diffraction gratings of the second diffraction layer. At least one of the first diffraction layer, the second diffraction layer and the cover layer contains dyes, and therefore, the optical film can reduce the light leakage defect of a conventional liquid crystal display in a large viewing angles and make the liquid crystal display have uniform dark-state images and colorful images.

Optical film for liquid crystal display

A light redirecting film and a method for manufacturing the same are provided. The light redirecting film comprises a substrate, a first diffraction grating layer of a first curable resin on the substrate and a second diffraction grating layer of a second curable resin on the first diffraction grating layer. Wherein the grating directions of the first diffraction grating layer and the second diffraction grating layer cross each other at an angle of 90&#xb1;10&#xb0;, and the difference of the refractive index of the first curable resin and the second curable resin is no less than 0.1 and no more than 0.3.

Light redirecting film and method for manufacturing the same

The invention provides an optical film for improving image quality of a liquid crystal display comprising: a light directing structure layer, a first filling layer, a plurality of first diffraction gratings and a second filling layer. The light directing structure layer comprises a plurality of light directing micro structures, wherein the ratio of height to width of each light directing micro structure is in the range of 1.5 to 6. The first filling layer is disposed on the light directing structure layer, and the refractive index of the first filling layer and the light directing structure layer are different. The first diffraction gratings along with a first direction are formed on the first filling layer. The second filling layer is disposed on the first diffraction gratings and the refractive index of the second filling layer and the first diffraction gratings are different.
