    摘要： A coordinate calibrating method includes the steps of: (1) reading paper coordinates by adopting two OID sensors, comparing the coordinates read by the two OID sensors with pre-designed coordinates of paper to obtain coordinate deviation of positions of the two OID sensors, and according to the coordinate deviation, calculating an inclination angle value θ generated by the coordinates of the two OID sensors; and (2) according to the coordinate deviation and the inclination angle value, calibrating an actually read coordinate position of a pen by selecting the second OID sensor as a reference point, translating horizontally and vertically coordinates of the pen to be corrected first, and then rotating the coordinates by the angle θ with reference to the second OID sensor, so that the positions of the two OID sensors coincide with pre-designed standard positions, and the coordinate position of the pen is calibrated.

    摘要： A display device includes a display unit having pixels, a touch sensing unit including touch electrodes disposed on the display unit, and a touch driver configured to supply a touch driving signal to the plurality of touch electrodes and receive a touch sensing signal from the touch electrodes. The touch driver supplies a first touch driving signal having a first phase to one or more first touch electrodes, and supplies a second touch driving signal having a second phase opposite to the first phase to one or more second touch electrodes, at least a part of which is disposed across a specific point from the first touch electrodes. The touch driver receives a first touch sensing signal having the first phase from at least one of the first touch electrodes, and receives a second touch sensing signal having the second phase from at least one of the second touch electrodes.

    摘要： A touchpad device is to be operated by using a stylus pen, and includes a touchpad and a controller that are connected to each other. The controller is connected to an electronic device that includes a display panel, and operates in a stylus-pen mode where a handwriting area is presented on the display panel. When it is determined that a distance between the stylus pen and the touchpad is less than a preset pen-hover distance but is non-zero, the controller operates in a hover-move sub-mode where the controller outputs, based on a result of determination as to whether the electronic device is an iPad or not, two different control signals respectively for two different results of the determination to enable the electronic device to present, in the handwriting area, the cursor moving respectively in two different manners, without presenting a trace of the cursor.
