Patent number: 10613295Abstract: The tri-axis close-loop feedback controlling module for electromagnetic lens driving device comprises a 6-pin Hall element. Two pins of the Hall element are coupled to an auto-focus module for providing a current to drive the auto-focus module to conduct auto-focusing operations along the Z-axis; while other four pins of the Hall element are coupled to a control unit. The control unit detects the X-Y axial positions of the auto-focus module relative to an OIS module and generates a control signal which is then sent to the Hall element. Therefore, the Hall element not only can provide its own feedback controlling function according to the Z-axial position of lens, but also can drive the auto-focus module based on the control signal corresponding to the X-Y axial positions of the auto-focus module, so as to achieve the goal of tri-axis close-loop feedback controlling for the electromagnetic lens driving device.Type: GrantFiled: September 18, 2017Date of Patent: April 7, 2020Assignee: TDK Taiwan CorporationInventors: Shu Shan Chen, Chao Chang Hu, Wen Chang Lin
