Patent number: 11025764Abstract: A method and a system for reducing current noise of a touch terminal are provided. The method includes: determining that a user receives a voice call via an earpiece of the touch terminal, and controlling the touch terminal to switch from a first touch scan frequency to a second touch scan frequency, where the second touch scan frequency is less than the first touch scan frequency. As can be seen, if the user receives the voice call via the earpiece of the touch terminal, the touch terminal is controlled to switch from the first touch scan frequency to the second touch scan frequency, to effectively reduce the current noise heard by the user by decreasing the touch scan frequency of the touch terminal, so that the periodic current noise is outside a frequency band perceptible to a human ear, thereby improving user experience when receiving the voice call.Type: GrantFiled: March 20, 2019Date of Patent: June 1, 2021Assignee: SHANGHAI AVIC OPTO ELECTRONICS CO., LTD.Inventors: Zhengyuan Huang, Xu Yang, Xupeng Wang, Zhi Zheng, Changchao Liu

Patent number: 10325535Abstract: A method for testing a display panel includes: applying a first level signal to a first sub-pixel and a third sub-pixel of a first pixel unit and applying a second level signal to a second sub-pixel of the first pixel unit; applying the second level signal to a first sub-pixel and a third sub-pixel of a second pixel unit and applying the first level signal to a second sub-pixel of the second pixel unit; and detecting a short circuit between adjacent sub-pixels. The first level signal has a voltage polarity opposite to a voltage polarity of the second level signal. Therefore, it is ensured that any two adjacent sub-pixels have opposite voltage polarities when the short circuit between adjacent sub-pixels of the display panel is detected. The method also provides improved testing abilities to detect an open circuit in a sub-pixel.Type: GrantFiled: January 31, 2017Date of Patent: June 18, 2019Assignees: Shanghai AVIC OPTO Electronics Co., Ltd., Tianma Micro-electronics Co., Ltd.Inventors: Xu Yang, Nana Tian, Xupeng Wang, Zhiyong Ren, Xiaoyuan Ding, Zhengyuan Huang
