Patent number: 9367190Abstract: The present invention discloses a method and system for touch signal recognition adapted to be used in a capacitive touch panel or apparatus. In order to achieve an objection of enhancement of a touch signal for recognition and getting rid of noise impact simultaneously, the present invention discloses a touch recognition method that actually includes two different measurement cycles to acquire two different sample voltage values. Consequently, noise impact can be removed by calculation of a sample voltage value difference between two different sample voltage values, at the same time, and the sample voltage value difference can provide a double magnitude as disclosed in the prior art to enhance accuracy for recognizing a user touch input while preventing from influence of noise.Type: GrantFiled: September 15, 2014Date of Patent: June 14, 2016Assignees: APEX MATERIAL TECHNOLOGY CORP., IMAGINATION BROADWAY LTD.Inventors: Ke-hao Ding, Zong-Bin Liao, Zhong-peng Qiu, Shang-Li Lee
