Publication number: 20220397756Abstract: An optical scanning device includes a substrate, a frame, a plurality of light source modules, and a scanning mirror assembly. The frame is disposed on the substrate to form an accommodating space, and includes a side wall and a reflective portion located on a top end of the side wall and having a light exit. The light source modules are disposed in the accommodating space, surround the scanning mirror assembly, and are configured to provide a plurality of light beams to the reflective portion. The scanning mirror assembly is disposed in the accommodating space and located on a transmission path of the light beams reflected by the reflective portion. The scanning mirror assembly includes a scanning element oscillating along at least one rotation axis and being configured to reflect the light beams to form a scanning light beam transmitted through the light exit out of the optical scanning device.Type: ApplicationFiled: May 26, 2022Publication date: December 15, 2022Applicant: Coretronic CorporationInventors: Kang-Hsi Li, Kuan-Wei Pan

Patent number: 9285580Abstract: A light valve module including a first shell, a second shell, a light valve, an elastic pad and a sealant is provided. The first shell has an opening. The second shell is assembled to the first shell. The first shell and the second shell form a containing space therebetween. The light valve is disposed in the containing space and is exposed by the opening. The elastic pad is disposed between the first shell and the second shell for sealing the containing space. The sealant is adhered at a periphery of the opening and the light valve for sealing the containing space. In addition, a projection device having the light valve module is also provided.Type: GrantFiled: October 23, 2012Date of Patent: March 15, 2016Assignee: Young Optics Inc.Inventors: Wei-Szu Lin, Kang-Hsi Li

Patent number: 9128357Abstract: A vehicular projection system including a projection apparatus, a beam splitting module, and two projection screens is provided. The projection apparatus provides at least one image light beam. The beam splitting module divides the image light beam into a first image light beam and a second image light beam. The two projection screens receive the first image light beam and the second image light beam respectively. Each of the first image light beam and the second image light beam respectively forms an image on one of the two projection screens corresponding thereto.Type: GrantFiled: July 12, 2012Date of Patent: September 8, 2015Assignee: Young Optics Inc.Inventors: Po-Jen Chung, Wei-Szu Lin, Chih-Hsien Tsai, Kang-Hsi Li, Hung-Chih Chou, Chien-Jung Huang

Publication number: 20130094002Abstract: A projection system used in a vehicle including a projection apparatus, a projection screen, and an image correction module is provided. The projection apparatus provides an image beam. The projection screen receives the image beam. The image beam forms an image on the projection screen. The projection screen is a non-flat plane. The image correction module corrects the image beam to compensate a distortion of the projected image based on the surface contour of the image screen.Type: ApplicationFiled: July 5, 2012Publication date: April 18, 2013Applicant: YOUNG OPTICS INC.Inventors: Po-Jen Chung, Wei-Szu Lin, Chih-Hsien Tsai, Kang-Hsi Li, Hung-Chih Chou, Chien-Jung Huang

Publication number: 20130088441Abstract: A touch display apparatus including a first projecting screen and a projection apparatus is provided. The first projecting screen has a first curved surface. The first curved surface is capable of receiving a touch input instruction and has at least one tactile sense identify region. A sense of touch of the tactile sense identify region is different from a sense of touch of the other regions of the first curved surface. The projection apparatus is capable of projecting a projecting beam toward the first curved surface so as to form an image.Type: ApplicationFiled: July 3, 2012Publication date: April 11, 2013Applicant: YOUNG OPTICS INC.Inventors: Po-Jen Chung, Wei-Szu Lin, Chih-Hsien Tsai, Kang-Hsi Li, Hung-Chih Chou, Chien-Jung Huang

Patent number: 8379320Abstract: A lens module includes a lens, a cam and an actuator. The lens has two driven parts disposed at one side of the lens. The cam is disposed beside the lens and has a rotation shaft and two cam surfaces, and a portion of the cam is located between the two driven parts. The two cam surfaces have the same shape and are on opposite sides of the cam. The two cam surfaces are in contact with the two driven parts respectively. The actuator is coupled with the rotation shaft and adapted to rotate the cam.Type: GrantFiled: July 27, 2011Date of Patent: February 19, 2013Assignee: Young Optics Inc.Inventors: Chih-Chien Lin, Kang-Hsi Li
