Publication number: 20180019080Abstract: A keyboard includes a base plate, a pressure sensing layer, a first key structure and a second key structure. The pressure sensing layer includes plural pressure sensing regions. Each of the first key structure and the second key structure corresponds to a pressure sensing region. Moreover, the first key structure and the second key structure are located over the corresponding pressure sensing regions. In response to different magnitudes of the depressing force, the corresponding pressure sensing regions are pushed by the first key structure and the second key structure. Consequently, the corresponding pressure sensing regions generate different pressure sensing signals. The pressure sensing layer can replace plural pressure sensing element. Consequently, the assembling process is simplified, and the assembling cost is reduced.Type: ApplicationFiled: September 6, 2016Publication date: January 18, 2018Inventor: Chung-Yuan Chen

Patent number: 9634661Abstract: An optical switch keyboard includes a circuit module and plural keys. The circuit module includes a circuit board, plural light emitters, plural light receivers and plural light sources. Each key corresponds to a light emitter, a light receiver and a light source. The plural light emitters and the plural light receivers are disposed under the circuit board. Consequently, the plural light emitters and the plural light receivers are not interfered by the ambient light that comes from the top side of the circuit board. In case that the light sources are disposed over the circuit board, the light beams from the light sources are transmitted upwardly through light-transmissible triggering elements of the corresponding keys and projected to the keycaps. Consequently, a visual effect is generated.Type: GrantFiled: May 17, 2016Date of Patent: April 25, 2017Assignee: PRIMAX ELECTRONICS LTD.Inventor: Chung-Yuan Chen

Publication number: 20170004936Abstract: A luminous keyboard includes a keypad module, plural light-emitting elements, a light guide plate and a reflecting plate. The reflecting plate has plural light amount control structures. The light amount control structures are disposed on the reflecting plate, and located near the corresponding light-emitting elements. When the plural light-emitting elements emit light beams, the portions of the light beams that are not subjected to total internal reflection within the light guide plate are reflected by the reflecting plate. When the light beams are transferred through the light amount control structure, the reflected fraction of the light beams is reduced. Since the light beams are not very centralized, the problem of generating bright spots will be diminished.Type: ApplicationFiled: August 20, 2015Publication date: January 5, 2017Inventor: CHUNG-YUAN CHEN
