Publication number: 20240103650Abstract: The present disclosure relates to a method of operating an OSD function for a public-place-device. The method includes: detecting a touch input through the touch screen while the OSD function is in the locked state; causing the OSD function to operate in the unlocked state in response to detecting a predetermined touch secret code, so as to output an OSD image on the display and conduct an OSD configuration of the display according to an OSD operation from an external entity; and causing the OSD function to operate in the locked state in response to receiving an OSD locking request while the OSD function is in the unlocked state, so as not to output the OSD image on the display and not to respond to an OSD operation from an external entity. The present disclosure also relates to an OSD system and a self-service device for the public-place-device.Type: ApplicationFiled: September 8, 2023Publication date: March 28, 2024Applicant: Elo Touch Solutions, Inc.Inventors: Shih-Tsung Chang, Chi-Liang Tai

Patent number: 10094965Abstract: A pattern displaying device includes a light path changing element, a first light source, a second light source, and a control module. The light path changing element has first inclined surfaces to reflect light and arranged into a first predetermined pattern, and second inclined surfaces to reflect light and arranged into a second predetermined pattern. The first light source is operable to emit light toward the first inclined surfaces to display the first predetermined pattern. The second light source is operable to emit light toward the second inclined surfaces in order to display the second predetermined pattern. The control module is electrically connected to the first and second light sources to control the first and second light source to emit light or not.Type: GrantFiled: November 11, 2015Date of Patent: October 9, 2018Assignee: TAIWAN GREEN POINT ENTERPRISES CO., LTD.Inventors: Ray-Long Tsai, Pei-Shan Hsieh, Tung-Chuan Chen, Cheng-Yen Wang, Shih-Tsung Chang

Patent number: 7950829Abstract: The high efficiency light emitting diode apparatus mainly comprises a connector, a heat dissipating body, a light generator, a central venting portion, and a transparent casing. This connector has a flow guider, a flow chamber and a vent. The light generator contains several LEDs. The heat dissipating body includes an inner passage and an outer passage. The central venting portion has a central channel. An inner flow path and an outer flow path are formed. So, the heat dissipating effect of the flow paths is excellent. The structure forming two flow paths can enhance the heat dissipating effect. The auxiliary element can strengthen the overall illuminating effect. Plus, the auxiliary element can make the light more uniformly.Type: GrantFiled: April 9, 2009Date of Patent: May 31, 2011Assignee: Taiwan Green Point Enterprises Co., Ltd.Inventors: Shao-Chen Chiu, Yih-Hua Renn, Ray-Long Tsai, Shih-Tsung Chang, Chi-Feng Cheng

Patent number: 6814457Abstract: The present invention relates to an improvement for a light guide structure for light guide plate so as to resolve the problems of illumination and degree of uniformity of the conventional light guide plate. The light guide plate of the present invention has line-shaped passages which are located in parallel with the direction of light from the light emitting diodes. The depth of the passages becomes deeper gradually from one end to the other, wherein the source of light is located close to the shallow end, thereby the light from the light emitting diodes is transmitted to the remote areas that are located far from the source of light. The present invention increases the total illumination and the degree of uniformity, and the efficiency of the light emitting diode is also increased.Type: GrantFiled: August 5, 2002Date of Patent: November 9, 2004Assignee: Taiwan Green Point Enterprise Co., Ltd.Inventors: Shih-Tsung Chang, Chi-Feng Cheng
