Patent number: 11003888Abstract: The present disclosure discloses a fingerprint recognition device, which includes a luminescent display panel, a substrate, an image capturing module, a plurality of first prism arrays and a plurality of second prisms. The first prism arrays are disposed on the substrate and paralleled to each other, and each of the first prism arrays receives an incident ray from the luminescent display panel. The first prism arrays provide a first light guiding direction, and the first light guiding direction is orthogonal to the incident ray. The second prisms are disposed on the substrate, and the second prisms are corresponding to the first prism arrays respectively. Each of the second prisms has a light-emitting surface, and the light-emitting surface faces toward the image capturing module. The second prisms provide a second light guiding direction, and the second light guiding direction is perpendicular to the first light guiding direction.Type: GrantFiled: October 23, 2019Date of Patent: May 11, 2021Assignee: Chicony Electronics Co., Ltd.Inventor: Chih-Liang Liao

Patent number: 8013965Abstract: A liquid crystal display device is disclosed, which comprises an upper substrate, a lower substrate, and a liquid crystal layer. The lower substrate has several pixel electrodes, metal lines, and switch elements thereon. Each switch element comprises a source electrode, a drain electrode, a gate electrode, and an opening between the source electrode and the drain electrode. A passivation layer covering the surface of the source electrode and the drain electrode forms two inclined planes separately on two sides. The two inclined planes face each other and are locating on a kink or step of the source electrode and drain electrode. The inclined planes also contact each other at the upper side of the opening. The inclinations of the inclined planes to the lower substrate are in a range from 5 to 50 degrees.Type: GrantFiled: September 3, 2010Date of Patent: September 6, 2011Assignee: AU Optronics CorporationInventors: Yeong-Feng Wang, Liang-Pin Yu, Chih-Liang Liao, Chien-Hung Chen, I-Hua Ho, Yi-Wei Lee
