Publication number: 20240053827Abstract: A touch feedback correction method and a touch module using the touch feedback correction method are provided. In the touch feedback correction method, the coordinate values and the initial vibration values of plural press region on a touch panel of the touch module are detected. Consequently, a driving voltage calibration table is established. Then, a vibrating unit of the touch module is driven according to plural compensated voltage values of the driving voltage calibration table. Consequently, the plural press regions generate plural corrected vibration values, respectively.Type: ApplicationFiled: August 31, 2022Publication date: February 15, 2024Inventors: Chieh-Hung Hsieh, Wei-Chiang Huang, Chao-Wei Lee, Chun-Pi Wang, Hsueh-Chao Chang, Sian-Yi Chiu

Patent number: 11899857Abstract: A touchpad module includes a base plate, a touch member, a supporting structure and a pressure sensing unit. The touch member is movable toward the base plate. The supporting structure is arranged between the base plate and the touch member. The pressure sensing unit is installed on the touch member. The pressure sensing unit is arranged between the touch member and the base plate. While the touch member is pressed in response to an external pressing force, the touch member is moved downwardly toward the base plate to compress the supporting structure. Consequently, the supporting structure is subjected to deformation, and the touch member has a displacement amount. According to the displacement amount, a magnitude of the pressing force is sensed by the pressure sensing unit, and a pressure sensing signal is outputted from the pressure sensing unit.Type: GrantFiled: March 8, 2023Date of Patent: February 13, 2024Assignee: PRIMAX ELECTRONICS LTD.Inventors: Wei-Chiang Huang, Hung-Wei Kuo, Chao-Wei Lee, Chen-Yu Wu

Patent number: 11726584Abstract: A touchpad module includes a base plate, a touch member, plural supporting elements, plural pressure sensing units and a feedback generation element. The base plate includes a plate body and plural elastic arms. The plural elastic arms are formed on the plate body. The plural supporting elements are arranged between the base plate and the touch member, and aligned with the corresponding elastic arms. While the touch member is moved toward the base plate, the plural supporting elements are move downwardly with the touch member to press the corresponding elastic arms. Consequently, the plural elastic arms are subjected to deformation. If the deformation amount of at least one of the plural elastic arms reaches a threshold value, the corresponding pressure sensing unit issues a pressure sensing signal. The feedback generation element generates a haptics feedback effect in response to the pressure sensing signal.Type: GrantFiled: September 26, 2022Date of Patent: August 15, 2023Assignee: PRIMAX ELECTRONICS LTD.Inventors: Wei-Chiang Huang, Chao-Wei Lee, Hsueh-Chao Chang, Chieh-Hung Hsieh, Sian-Yi Chiu

Patent number: 11640215Abstract: A touchpad module includes a touch member, a base plate, a supporting element and a switch. The touch member includes a first touch region and a second touch region. The base plate is located under the touch member. The supporting element is arranged between the touch member and the base plate. The supporting element is aligned with the second touch region. The switch is arranged between the touch member and the base plate. The switch is aligned with the second touch region. When a pressing force is applied to the second touch region of the touch member, the pressing force is transmitted to the base plate through the supporting element. Consequently, the base plate is subjected to deformation. The switch is triggered in response to the deformation of the base plate.Type: GrantFiled: July 1, 2022Date of Patent: May 2, 2023Assignee: PRIMAX ELECTRONICS LTD.Inventors: Wei-Chiang Huang, Chao-Wei Lee, Hsueh-Chao Chang, Sian-Yi Chiu

Patent number: 11402931Abstract: A touchpad module includes a touch member, a first base plate, a second base plate and two elastic elements. The first base plate includes a first stopping part and a second stopping part. The second base plate is arranged between the touch member and the first base plate. The second base plate include a third stopping part and a fourth stopping part. The third stopping part is engaged with the first stopping part. The fourth stopping part is engaged with the second stopping part. The two elastic elements are arranged between the first base plate and the second base plate. When an external force is exerted on the touch member, the touch member is swung toward the first base plate by using a junction between the second stopping part and the fourth stopping part as a fulcrum.Type: GrantFiled: December 30, 2021Date of Patent: August 2, 2022Assignee: PRIMAX ELECTRONICS LTD.Inventor: Chao-Wei Lee
