Publication number: 20240045518Abstract: Disclosed herein is a method executed by a device that is configured to be able to detect a pointed position of a stylus on an operation plane being superimposed on a displaying part. The method includes receiving feedback information relating to a display position of a predetermined pattern on the displaying part from a host processor, updating at least some of plural position calibration values stored in a correction table that stores therein the position calibration value for each of plural positions arranged on the operation plane, on a basis of the received feedback information, detecting a tentative pointed position of the stylus, reading the position calibration value that corresponds to the tentative pointed position from the correction table and deriving an output position by correcting the tentative pointed position on a basis of the position calibration value, and reporting the output position to the host processor.Type: ApplicationFiled: October 20, 2023Publication date: February 8, 2024Applicant: Wacom Co., Ltd.Inventors: Shunya Saito, Shigeyuki Sano, Igor Karsuntsev, JuiMin Liu, Jun Kadowaki

Publication number: 20220308687Abstract: A controller of an in-cell type liquid crystal display device is provided. The controller controls first and second electrodes that intersect each other, supplies a pixel driving voltage to the first electrodes during a pixel driving period, and detects a stylus position using the first and second electrodes during a stylus detection period different from the pixel driving period. The controller transmits, using the second electrodes, a command requesting a transmission of a downlink signal to the stylus. The controller detects, using the first and second electrodes, the downlink signal transmitted from the stylus in response to the command, and detects the stylus position based on the detected downlink signal.Type: ApplicationFiled: June 13, 2022Publication date: September 29, 2022Inventors: Hideyuki Hara, Sadao Yamamoto, Shunya Saito

Patent number: 10061407Abstract: A stylus usable with non-in-cell type and in-cell type electronic apparatuses is provided. A stylus, in operation, transmits pen pressure data P to an electronic apparatus. The stylus includes a stylus electrode and a signal processing circuit. The stylus electrode forms a coupling capacitance with a sensor electrode of the electronic apparatus. The signal processing circuit detects an uplink signal US using the stylus electrode, extracts a command from the detected uplink signal US, determines, based on the extracted command, in which mode to operate between a first mode in which the data is transmitted using M (M?1) first periods and a second mode in which the data is transmitted using N (N>M) second periods, and repeatedly transmits the data in accordance with the determined mode.Type: GrantFiled: December 6, 2017Date of Patent: August 28, 2018Assignee: Wacom Co., Ltd.Inventors: Hideyuki Hara, Sadao Yamamoto, Shunya Saito
