Patent number: 9547030Abstract: The disclosure relates to a method for recognizing touch. A first value T1 and a second value T2 are set. A number of first sensing values C1 are obtained. C1 is compared with T1 and T2. When C1 is greater than or equal to T1, a touch with finger is recognized. When C1 is smaller than T2, no touch is recognized. When C1 are greater than or equal to T2 and smaller than T1, following steps are taken. A third value T3 is set. At least three driving electrodes are driven and a number of second sensing values C2 are obtained. A number of maximum sensing values C2peak are selected from the C2 and compared with T3. When C2peak are greater than or equal to T3, a touch with glove is recognized. And when not, no touch is recognized.Type: GrantFiled: January 5, 2014Date of Patent: January 17, 2017Assignee: TIANJIN FUNAYUANCHUANG TECHNOLOGY CO., LTD.Inventors: Li-Min Chao, Chien-Yung Cheng, Po-Sheng Shih

Patent number: 9405420Abstract: A method for controlling a touch panel is disclosed. A first driving signal is applied to the driving electrodes to obtain a number of first electrical signals corresponding to a number of conductive stripes of touch panel. The first electrical signals are converted into a number of first digital signals by digital analog conversion with a first factor. A second driving signal is applied to a number of driving electrodes to obtain a number of second electrical signals corresponding to a number of button electrodes of the touch panel. The second electrical signals are converted into a number of second digital signals by digital analog conversion with a second factor. The second factor is smaller than the first factor.Type: GrantFiled: November 25, 2014Date of Patent: August 2, 2016Assignee: TIANJIN FUNAYUANCHUANG TECHNOLOGY CO., LTD.Inventors: Chien-Yung Cheng, Po-Sheng Shih, Li-Min Chao

Patent number: 9329740Abstract: The disclosure relates to a method for recognizing touch. A first value T1 and a second value T2 are set. A maximum sensing value Cpeak is obtained. A position of the Cpeak is defined as a sensing position A. Sensing values C1, C2, C3, and C4 of four neighboring sensing positions are obtained. Cpeak is compared with T1 and T2. When Cpeak is greater than or equal to T1, a touch with finger is recognized. When Cpeak is smaller than T2, no touch is recognized. When Cpeak is greater than or equal to T and smaller than T1, following steps are taken. A third value T3 is set. A first total sensing value Ct of C1, C2, C3, and C4 is compared with T3. When Ct is greater than or equal to T3, a touch with glove is recognized. When Ct is less than T3, no touch is recognized.Type: GrantFiled: January 8, 2014Date of Patent: May 3, 2016Assignee: TIANJIN FUNAYUANCHUANG TECHNOLOGY CO., LTD.Inventors: Li-Min Chao, Chien-Yung Cheng, Po-Sheng Shih

Patent number: 9262008Abstract: The disclosure relates to a method for recognizing touch on a touch panel. A first value and a second value are set. Sensing value Cn is compared with the first value and the second value. When the sensing value Cn is greater than or equal to the first value, a touch with finger is recognized. When the sensing value Cn is smaller than the second value, no touch is recognized. When the sensing values Cn are greater than or equal to the second value and smaller than the first value, following steps are taken. A time period is setting. Touch signals are sensed several times during the time period and a number of maximum sensing values ?Cpeak are selected. Average sensing values ?Cpeak are calculated. When the average sensing values ?Cpeak satisfy following formula: 0.8 ?Cpeak??Cpeak?1.2 ?Cpeak, a touch with glove is determined. And when not, no touch is recognized.Type: GrantFiled: January 8, 2014Date of Patent: February 16, 2016Assignee: TIANJIN FUNAYUANCHUANG TECHNOLOGY CO., LTD.Inventors: Li-Min Chao, Chien-Yung Cheng, Po-Sheng Shih

Publication number: 20150145795Abstract: A method for controlling a touch panel is disclosed. A first driving signal is applied to the driving electrodes to obtain a number of first electrical signals on a first area of the touch panel. The first electrical signals are converted into a number of first digital signals by digital analog conversion with a first factor. A second driving signal is applied to a number of driving electrodes to obtain a number of second electrical signals on a second area of the touch panel. The second electrical signals are converted into a number of second digital signals by digital analog conversion with a second factor. The second factor is greater than the first factor.Type: ApplicationFiled: November 25, 2014Publication date: May 28, 2015Inventors: CHIEN-YUNG CHENG, PO-SHENG SHIH, LI-MIN CHAO

Publication number: 20150091860Abstract: A method for preventing a false activation of a touch pad is provided. In the method, a touch area of the touch pad is divided into subareas. A lock threshold Nlock and a sensing signal threshold Vlock are set. The touch pad is scanned when there is a touch acted on the touch pad. A quantity Ni of touch points in each of the subareas is counted. If the quantity Ni of the touch points in a certain subarea is less than Nlock, the one subarea is maintained touchable, if not, the certain subarea is maintained untouchable.Type: ApplicationFiled: September 29, 2014Publication date: April 2, 2015Inventors: PO-SHENG SHIH, CHIEN-YUNG CHENG, LI-MIN CHAO
