Patent number: 8654105Abstract: An optical touch control system. A monitor includes a first side, a second side, a third side, and a fourth side sequentially connected to each other. A first light guide, a second light guide, and a third light guide are respectively disposed on the first, second, and third sides of the monitor. A first beam splitter is adjacent to the first and second light guides. A second beam splitter is adjacent to the second and third light guides. A first light source and a second light source are respectively adjacent to the first and second beam splitters. A first image sensor is disposed between the first and fourth sides of the monitor. A second image sensor is disposed between the third and fourth sides. The first and second image sensors receive light transmitted onto the monitor via the first, second, and third light guides, identifying touch control operations.Type: GrantFiled: September 16, 2013Date of Patent: February 18, 2014Assignee: Quanta Computer Inc.Inventors: Chien-Hung Lin, Chen-Kuan Lin

Publication number: 20120032922Abstract: An optical touch system includes a substrate, at least one sensor, a processing unit and an analysis unit. The substrate has a touch region. The at least one sensor is used for capturing a full-size image of the touch region, wherein the full-size image includes a central region image near a light axis of the at least one sensor, and a side region image. The processing unit is used for sampling the central region image to obtain a central compressed image and transmitting the central compressed image and the side region image under a normal mode. The analysis unit is used for analyzing the central compressed image and the side region image to obtain a touch point coordinate.Type: ApplicationFiled: November 24, 2010Publication date: February 9, 2012Applicant: Quanta Computer Inc.Inventors: Ping-Chung Lin, Chen-Kuan Lin, Yi-Chien Lin, Yu-Chen Chen

Publication number: 20120032921Abstract: An optical touch system includes a first light source, a second light source, a sensing module and a processing module. The lighting timing of the second light source differs with the lighting timing of the first light source by a phase. The sensing module is for capturing a sensing image related to a touch point on a panel, and receiving a first bounce light of the touch point corresponding to the first light source and a second bounce light of the touch point corresponding to the second light source. The processing module is for obtaining angle information according to the sensing image, calculating a phase difference between the first bounce light and the second bounce light to obtain distance information, and determining a coordinate corresponding to the touch point according to the angle information and the distance information.Type: ApplicationFiled: November 24, 2010Publication date: February 9, 2012Applicant: Quanta Computer Inc.Inventors: Ping-Chung Lin, Chen-Kuan Lin, Yu-Chen Chen, Yi-Chien Lin

Publication number: 20110102375Abstract: An optical touch module includes a display panel, an optical sensor and a light emitting unit. The optical sensor is disposed on a corner of the display panel. The light emitting unit is disposed on the optical sensor and includes a light emitting member and a compensating member. The light emitting member emits light with a first light strength along a first direction and light with a second light strength along a second direction, wherein the first light strength is greater than the second light strength. The compensating member is disposed on a side of the light emitting member. After the lights pass through the compensating member, the second light strength is increased.Type: ApplicationFiled: April 19, 2010Publication date: May 5, 2011Applicant: QUANTA COMPUTER INC.Inventors: Yun-Cheng Liu, Chien-Hung Lin, Bo-Yi Wu, Chen-Kuan Lin, Kuan-Chun Hsieh, Yi-Chien Lin
