Patent number: 10452204Abstract: An optical touch control system and an optical sensor thereof are provided. The optical sensor can be applied to a display having a display surface. The optical sensor includes a connecting frame, a light curtain module and a light emitter. The connecting frame has a first end portion and a second end portion opposite the first end portion. The light curtain module is disposed between the first end portion and the second end portion of the connecting frame. The light curtain module includes a light emitter electrically connected to the display so as to generate an invisible light curtain parallel to the display surface. The optical detection module is disposed on the second end portion of the connecting frame. The optical detection module includes a light detector electrically connected to the display so as to retrieve information about a touch location where an object touches the invisible light curtain.Type: GrantFiled: August 29, 2017Date of Patent: October 22, 2019Assignee: EVEREST DISPLAY INC.Inventors: Hei-Tai Hong, Yueh-Hong Shih, Chun-Yuan Cheng

Patent number: 9942530Abstract: The present disclosure provides a projection system and a light screen generating device thereof. The light screen generating device includes a movable carrier module, a first light-emitting module, and a second light-emitting module. The first light-emitting module includes a plurality of first light-emitting structures disposed on the movable carrier module. Each of the first light-emitting structures generates an invisible light screen, and the invisible light screens respectively generated by the first light-emitting structures are mated with each other to form a spliced invisible light screen for increasing light emission uniformity. The second light-emitting module includes a second light-emitting structure that is disposed on the movable carrier module and that generates a visible light screen parallel to and overlapping the spliced invisible light screen.Type: GrantFiled: May 5, 2017Date of Patent: April 10, 2018Assignees: EVEREST DISPLAY INC., SEAN & STEPHEN CORPORATIONInventors: Hei-Tai Hong, Yueh-Hong Shih, Chi-Jung Chen, Gang-Liang Wey, Hsin-Chin Chen

Patent number: 9904415Abstract: An interactive display system includes an input device and an image interaction module. The input device has a touch portion including a built-in first light-emitting module and a built-in second light-emitting module. The image interaction module includes a display module, a first image-capturing module, a second image-capturing module and a processing module. The processing module captures invisible light generated by the first light-emitting module through the first image-capturing module, for determining and obtaining the position of the touch portion. The processing module captures visible light generated by the second light-emitting module through the second image-capturing module according to the position of the touch portion, for determining and obtaining a predetermined color light source provided by the visible light generated by the second light-emitting module.Type: GrantFiled: December 23, 2014Date of Patent: February 27, 2018Assignee: EVEREST DISPLAY INC.Inventors: Hei Tai Hong, Fu Hsiung Lee, Sing Wu, Wan Yu Hong, Yueh Hong Shih, Shih Chieh Lu

Publication number: 20130321342Abstract: An optical touch screen expansion method comprises a primary optical touch module setting process and at least one expanded optical touch module setting process that respectively enable a host to acquire original touch position information according to an identification code thereof and work out information of an absolute position of a touch point via a touch position calibration algorithm, whereby the host can simultaneously control several optical touch modules. Therefore, the present invention enables a single host (i.e., identical software) to control several optical touch modules.Type: ApplicationFiled: June 1, 2012Publication date: December 5, 2013Inventors: CHUN-YUAN CHENG, YUEH-HONG SHIH

Patent number: 7703926Abstract: A briefing system is used to project images onto a projection screen to form a projection picture. The briefing system comprises a pointer, a projector and a computer electrically connected to the projector. The computer outputs an image signal to the projector. The projector projects an image corresponding to the image signal onto the projection screen to form the projection picture. The indicator is used to project an indication point. The projector also captures the image of the projection picture and the indication point and transfers the image to the computer. The computer then calculates a location where the cursor on the computer screen should reach according to the location of the indication point on the projection picture and moves the cursor on the screen to there.Type: GrantFiled: September 27, 2006Date of Patent: April 27, 2010Assignee: Everest Display Inc.Inventors: Hei-Tai Hong, Yueh-Hong Shih

Publication number: 20090128783Abstract: The present invention discloses an ocular-protection projector device, wherein the projector is additionally equipped with an image-capture unit. When the projector projects information onto a screen, the image-capture unit captures the human-shape image of a user. An image-processing unit, which is arranged inside the projector or an external electronic device, receives the human-shape image, creates a human-shape black mask, and outputs the human-shape black mask via the projector onto an area of the screen corresponding to the user's position. Thereby, the present invention can effectively protect the user's eyes from the harm of intense light.Type: ApplicationFiled: November 15, 2007Publication date: May 21, 2009Inventors: Yueh-Hong Shih, Hei-Tai Hong, Chun-Yuan Cheng
