Patent number: 9804403Abstract: An optical substrate has a structured surface that enhances brightness and reduces moire effect. The optical substrate has a three-dimensionally varying, structured light output surface that comprises an irregular prismatic structure. The irregular prismatic structure may be viewed as comprising longitudinal prism blocks or rows thereof, arranged laterally defining peaks and valleys. Adjacent peaks, adjacent valleys, and/or adjacent peak and valley may be parallel or non-parallel, in an orderly, semi-orderly, random, or quasi-random manner. The lateral adjacent peaks, adjacent valleys, and/or adjacent peak and valley are not parallel. The adjacent irregular prism blocks may be irregular longitudinal sections having the same length, or random or quasi-random irregular sections having different lengths. The facets of each prism block may be flat, or curved (convexly and/or concavely).Type: GrantFiled: April 15, 2016Date of Patent: October 31, 2017Assignee: UBright Optronics CorporationInventors: Kong-Hua Wang, Craig Lin, Daniel Yaw-Chung Ko

Patent number: 8367186Abstract: An optical substrate possesses a structured surface that enhances luminance or brightness and reduces the effects of structural defects on perceived image quality. User perceivable image cosmetic defects caused by manufacturing or handling, can be masked by introducing structural irregularities in the optical substrate, which may be non-facet flat sections or in-kind to the defects. Optical defects caused by non-facet flat sections in the prism structure of the optical substrate (e.g., flat-bottom valleys with a certain valley bottom thickness above the base layer, and/or flat-top peaks, and/or openings in the optical substrates that expose flat sections of underlying base layer) can be masked by providing distributed in-kind non-facet flat sections (e.g., flat-bottom valleys, and/or flat-top peaks, and/or openings exposing sections of underlying base layer), to diffuse the prominence of the original defects with the introduced irregularities.Type: GrantFiled: February 2, 2011Date of Patent: February 5, 2013Assignee: Ubright Optronics CorporationInventors: Kong-Hua Wang, Craig Lin, Daniel Yaw-Chung Ko

Patent number: 7712944Abstract: An optical substrate possesses a structured surface that enhances luminance or brightness and reduces chatter phenomenon. A structured surface is provided, in which some of the valleys (low valleys) are coplanar to the surface of the underlying support layer and other valleys (high valleys) are not coplanar on the support layer. The low valleys have bottom thickness that is substantially smaller than that of the high valleys. The distance from the valleys to the support layer remains substantially similar for a first number of adjacent valleys, but is substantially zero for a second number of adjacent valleys after every n-th adjacent valleys.Type: GrantFiled: December 6, 2006Date of Patent: May 11, 2010Assignee: Ubright Optronics CorporationInventors: Kong-Hua Wang, Craig Lin, Daniel Yaw-Chung Ko
