Patent number: 11630530Abstract: The present invention is a touch panel with a heater for enhancing the bonding of optical adhesive, which comprises a cover lens and a sensing substrate mutually bonded by optical adhesive, wherein at least one heating electrode is configured on the other side of the sensing substrate. The heating electrode is formed by printing an opaque conductive material with a plurality of openings formed thereon and through which light is allowed to pass. When ultraviolet light is irradiating from one side of the heating electrode to the direction of the cover lens, the ultraviolet light can penetrate the optical adhesives through the openings on the heating electrode, so that the optical adhesives are effectively cured by the irradiation, and the bonding strength between the cover lens and the sensing substrate is improved.Type: GrantFiled: March 24, 2022Date of Patent: April 18, 2023Assignee: EMERGING DISPLAY TECHNOLOGIES CORP.Inventors: Han-Tsung Wu, Po-Tsun Liu, Chao-Ping Wu

Patent number: 11630573Abstract: A hover touch device with sensory feedback includes: a capacitive touch panel, and a touch driver chip which drives the capacitive touch panel to generate and output a sensing information; based on the sensing information, an embedded system determines whether a conducting object is inside an effective region. The embedded system calculates spatial coordinates of the conductive object, and outputs the spatial coordinates to a graphical user interface, so that the graphical user interface displays a position feedback image on a display device based on the spatial coordinates of the conductive object as a visual feedback. After the embedded system recognizes a hovering gesture event, a speaker generates a hovering gesture event feedback sound as an auditory feedback. The embedded system also makes the speaker broadcast a warning sound when a user's finger contacts the capacitive touch panel.Type: GrantFiled: April 4, 2022Date of Patent: April 18, 2023Assignee: EMERGING DISPLAY TECHNOLOGIES CORP.Inventor: Po-Wei Lin

Patent number: 11506886Abstract: A spatial image display touch device includes an imaging element, a display, an optical film and a sensor unit. The imaging element and the display are retained in a housing and inclined to each other. The display generates an image light passing through the imaging element to form a spatial image. The optical film, composed of a plurality of micro-grids arranged in a matrix, is attached on the display. The sensor unit is mounted in the housing to detect an object appearing at the position wherein the spatial image is displayed. By arranging the optical film in front of the display, only the spatial image is visible and the problem of ghost images is avoided.Type: GrantFiled: October 25, 2021Date of Patent: November 22, 2022Assignee: EMERGING DISPLAY TECHNOLOGIES CORP.Inventors: Po-Tsun Liu, Chao-Ping Wu
