Patent number: 9726926Abstract: Disclosed herein is a display device including a reflection type image display portion having a sheet-like anisotropic scattering member. In an area, in an in-plane direction, of the anisotropic scattering member, a low-refractive index area and a high-refractive index area are disposed in a mixture style. The anisotropic scattering member is disposed so that a light is scattered when an outside light is made incident from a surface side on which a degree of a change in a refractive index in a vicinity of a boundary between the low-refractive index area and the high-refractive index area is relatively large, and is emitted from a surface side on which the degree of the change in the refractive index in the vicinity of the boundary between the low-refractive index area and the high-refractive index area is relatively small.Type: GrantFiled: November 16, 2016Date of Patent: August 8, 2017Assignee: JAPAN DISPLAY INC.Inventor: Masashi Mitsui

Patent number: 9588370Abstract: A display device is disclosed. The display device includes a display and a diffractive optical element (DOE). The display is used to show an image. When a user looks at the image within a first viewing angle range, he can see a first observed image, and when he looks at the image within a second viewing angle range, he can see a second observed image. The diffractive optical element is disposed in the lighting direction of the display to diffract the light constructing the first observed image to the second viewing angle range, thereby converting the first observed image into a third observed image and converting the second observed image into a fourth observed image at the same time.Type: GrantFiled: August 3, 2011Date of Patent: March 7, 2017Assignee: CHI MEI MATERIALS TECHNOLOGY CORPORATIONInventors: Ting-I Wu, Wang-Yang Li

Patent number: 9581731Abstract: A distortion-reducing anti-glare (DRAG) structure is disclosed, wherein the DRAG structure includes first and second transparent mediums. The first transparent medium has a first refractive index and a first light-scattering anti-glare (AG) surface. The first AG surface by itself reduces glare but introduces an amount of distortion to the transmitted light. A second transparent medium having a second refractive index greater than the first refractive index is selectively added to the first transparent medium to reduce the amount of distortion in the transmitted light.Type: GrantFiled: May 31, 2013Date of Patent: February 28, 2017Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Shandon Dee Hart, Karl William Koch, III, James Andrew West
