Patent number: 11650682Abstract: Embodiments of the present disclosure relate to a touch display device, a data driving circuit, and a touch sensing method. By sensing multiple data lines simultaneously using gate signals for display as touch driving pulses, it is possible to provide touch sensing without having a separate touch electrode for touch sensing and touch driving pulses. The touch sensing method includes outputting gate signals sequentially having a pulse section including two or more pulses to gate lines, by a gate driving circuit; outputting an image data voltage to data lines, by a source driving circuit; sensing the data lines by combining every N (N is a natural number of 2 or more) data lines or sensing a plurality of reference voltage lines by combining every N reference voltage lines, by a sensing circuit; and determining a touch or a touch coordinate, based on sensing values obtained by sensing of the sensing circuit.Type: GrantFiled: December 8, 2020Date of Patent: May 16, 2023Assignee: LG DISPLAY CO., LTD.Inventors: HyeongWon Kang, Jaehun Jun

Patent number: 11650687Abstract: A tactile touch sensor (TTS) system and method allowing physical augmentation of a high-resolution touch sensor array (TSA) is disclosed. Physical augmentation is accomplished using a TSA physical overlay (TPO) placed on top of the TSA. The TPO is constructed to transmit forces to the underlying TSA. Force transmission is accomplished by either using a flexible overlay or with a rigid mechanical overlay that transmits user forces exerted on the overlay to the underlying TSA. Incorporation of TPO identifiers (TPI) within the TPO permits identification of the TPO by a TPO detector (TPD) allowing operational characteristics of the TSA to be automatically reconfigured to conform to the currently applied TPO structure by a user computing device (UCD). The UCD may be configured to automatically load an appropriate application software driver (ASD) in response to a TPI read by the TPD from the currently applied TPO.Type: GrantFiled: December 16, 2021Date of Patent: May 16, 2023Assignee: SENSEL, INC.Inventors: Ilya Daniel Rosenberg, John Aaron Zarraga

Patent number: 11650721Abstract: Disclosed herein are clutch and boom features that can enable the manipulation of user interface elements when using a touch-sensitive component to build or otherwise design a graphical display, such as a website, video game, magazine layout, etc. Upon touching user interface element to be manipulated, the user interface element can be targeted for manipulation. In response to a clutch user interface element being engaged, the targeted user interface element can be enabled for manipulation (e.g., colored, rotated, moved, etc.) by the user, while the non-targeted user elements are protected from manipulation. Boom is an example of manipulation functionality provided by some embodiments, which can be configured to move the targeted user interface element a precise amount (e.g., pixel-by-pixel).Type: GrantFiled: January 17, 2022Date of Patent: May 16, 2023Assignee: Newman Infinite, Inc.Inventor: Matthew Allan Newman
