Patent number: 11175770Abstract: A touch device has multiple charging traces distributed under the touch operation area. When the object hovers over or contacts the touch operation area, the control unit of the touch device obtains the corresponding position of the object through the sensing signal of the electrode units. The control unit in turn connect the charging traces adjacent to the corresponding position of the object to form at least one charging loop. In the process of the touch operation on the touch device, the object can be charged at the same time, and the convenience of use can be improved.Type: GrantFiled: October 14, 2019Date of Patent: November 16, 2021Assignee: ELAN MICROELECTRONICS CORPORATIONInventors: Han-Wei Chen, Hsuan-Wen Tseng, Yi-Hsin Tao, Chia-Hsing Lin

Patent number: 10921942Abstract: A touch system has a touch device and an input device. The touch system executes a first mode and a second mode at different times. In the first mode, the touch device transmits a modulation signal to drive the touch electrodes and to be used as an uplink signal. The input device receives the modulation signal. In the second mode, the touch device receives the downlink signal from the input device. Thus, the touch device does not have to transmit the driving signal and the uplink signal at different times. Then the time is saved for the rest work periods so that every work periods get longer length of time.Type: GrantFiled: October 17, 2019Date of Patent: February 16, 2021Assignee: ELAN MICROELECTRONICS CORPORATIONInventors: Han-Wei Chen, Hsuan-Wen Tseng, Yi-Hsin Tao, Chia-Hsing Lin, Chen-Yu Hou, Chieh-Wen Chen

Patent number: 10845918Abstract: A touch system includes a touch device and an input device. The uplink signal transmitted by the touch device includes a timestamp. The input device transmits a downlink signal through the electrode unit and transmits a side information through a wireless communication unit. The inclusion of the corresponding timestamp in the side information ensures that the side information is combined with the corresponding downlink signal to correctly present the user's operation.Type: GrantFiled: September 5, 2019Date of Patent: November 24, 2020Assignee: ELAN MICROELECTRONICS CORPORATIONInventors: Han-Wei Chen, Hsuan-Wen Tseng, Yi-Hsin Tao, Chia-Hsing Lin

Patent number: 9069419Abstract: Methods are proposed for object positioning for an X-Y projected capacitive touch panel. In an embodiment, capacitance sensing under inphase excitation of traces is applied to set a base value when the capacitive touch panel is not touched and to obtain capacitances at intersections when the capacitive touch panel is touched, and the base value is compared with the measured capacitances to identify touch points. In other embodiments, X-Y projected sensing and all-point sensing are combined to reduce the amount of calculation and achieve the same positioning effect as an all-point capacitive touch panel.Type: GrantFiled: August 26, 2010Date of Patent: June 30, 2015Assignee: ELAN MICROELECTRONICS CORPORATIONInventors: Chia-Hsing Lin, Yi-Hsin Tao, Hung Nien, Brian Sung, Hsin-Shieh Tsai, Hsuan-Wen Tseng

Patent number: 8674960Abstract: A detector circuit and detect method of a capacitive touch panel conditionally abort sensing of useless traces of the capacitive touch panel when the capacitive touch panel senses the traces thereof. For a selected trace, the trace voltage thereof is sampled to be compared with a threshold voltage. If the sampled voltage is lower than the threshold voltage, the sensing of this trace is aborted and thus the operation of the detector circuit is reduced to improve the performance of the capacitive touch panel.Type: GrantFiled: August 25, 2010Date of Patent: March 18, 2014Assignee: Elan Microelectronics CorporationInventors: Chia-Hsing Lin, Yi-Hsin Tao, Hsuan-Wen Tseng

Patent number: 8508501Abstract: A detect method of a capacitive touch panel alternately senses the traces of the capacitive touch panel to generate two series of fields, interpolates with the first fields to obtain interpolation fields having temporal coordinates identical to that of the second fields, and combines the second fields and the interpolation fields to generate reconstructed frames for coordinate calculation. Therefore, the capacitance sensing sequence of the traces is scheduled in a multi-field way to reduce the operation of the detector circuit of the capacitive touch panel.Type: GrantFiled: August 24, 2010Date of Patent: August 13, 2013Assignee: Elan Microelectronics CorporationInventors: Chia-Hsing Lin, Yi-Hsin Tao, Hsuan-Wen Tseng

Patent number: 8487908Abstract: A detector circuit and detect method of a capacitive touch panel conditionally abort detection of useless traces of the capacitive touch panel when the capacitive touch panel detects the traces thereof. For a selected trace, first several digital values obtained by detecting the selected trace are compared with a threshold value to identify whether the selected trace is useful or not, and if the selected trace is identified useless, an abort signal is triggered to abort detection of the selected trace. Therefore, the performance of the capacitive touch panel is improved with higher frame rate and less power consumption.Type: GrantFiled: August 24, 2010Date of Patent: July 16, 2013Assignee: Elan Microelectronics CorporationInventors: Chia-Hsing Lin, Yi-Hsin Tao, Hsuan-Wen Tseng
