Patent number: 11073940Abstract: A touch substrate, a touch device and a touch detection method are provided. The touch substrate includes: a base substrate, including a touch region and a trace region surrounding the touch region; multiple sensing electrodes arranged in the touch region; and multiple sensing electrode traces arranged in the trace region and connected to the multiple sensing electrodes respectively. The sensing electrodes includes first sensing electrodes and second sensing electrodes, each first sensing electrode is connected at a first side of the touch region to a sensing electrode trace, and each second sensing electrode is connected at a second side of the touch region opposite to the first side to a sensing electrode trace. In this disclosure, sensing electrodes are connected at two opposite sides of the touch region to the sensing electrode traces, therefore, two sensing electrodes may be scanned each time, shortening a scanning period of the sensing electrodes.Type: GrantFiled: March 28, 2019Date of Patent: July 27, 2021Assignees: Mianyang Boe Optoelectronics Technology Co., Ltd., Boe Technology Group Co., Ltd.Inventors: Yingxi Cui, Hu Zhang, Le Peng, Jiang Jing, Zhengde Liu, Lubiao Sun, Yunte Chen
