Abstract: A touch detection circuit and a touch detection method are provided. The touch circuit coupled to touch areas of touch panel includes a touch controller and a detection circuit. The touch controller performs a touch detection on the touch areas sequentially. The detection circuit transmits a first detection signal to a boundary area of the touch areas which are not touch detected to receive a first feedback signal. The detection circuit transmits a second detection signal to a corresponding central area of the touch areas which are not touch detected to receive a second feedback signal. The touch controller compares the first feedback signal and the second feedback signal to generate a capacitance variation between the boundary area and the corresponding central area.

Abstract: A conductive member has a wiring portion, and the wiring portion has a mesh-shaped wiring pattern in which line wirings each being composed of a plurality of thin metal wires arranged in parallel in one direction are overlapped in two or more directions. The line wiring in at least one direction is a straight line wiring in which a plurality of thin metal wires are straight lines. The straight line wiring in at least one direction has a non-equal pitch wiring pattern in which repetitive pitches of a predetermined number of the thin metal wires are equal and at least two pitches of the respective pitches of the predetermined number of the thin metal wires are different. The conductive member has a wiring pattern capable of reducing moiré compared to an equal pitch wiring pattern, particularly a wiring pattern capable of reducing both regular moiré and irregular moiré (noise). A conductive film, a display device, and a touch panel each include the conductive member.

Abstract: A touch-screen-controller (TSC) performs mutual sensing to acquire touch strength values from a touch matrix formed by capacitively intersecting conductive lines. For each line, the TSC generates an emulated self capacitance value from an associated touch strength value based upon a position of that line compared to a location on the touch matrix adjacent to which a first touch type is expected to occur, and determines presence of the first touch type adjacent to the touch matrix based upon the emulated values. The emulated values for each conductive line may be weighted based upon its closeness to the location where the first touch type is expected to occur. The weighting may be zero if its associated conductive line is outside of the location where the first touch type is expected to occur, and may be one if inside of the location where the first touch type is expected to occur.

Abstract: In some examples, an electronic device can use machine learning techniques, such as convolutional neural networks, to estimate the distance between a stylus tip and a touch sensitive surface (e.g., stylus z-height). A subset of stylus data sensed at electrodes closest to the location of the stylus at the touch sensitive surface including data having multiple phases and frequencies can be provided to the machine learning algorithm. The estimated stylus z-height can be compared to one or more thresholds to determine whether or not the stylus is in contact with the touch sensitive surface.

Abstract: The present invention provides a new and useful hybrid digital and physical interactive writing surface. A user writes on a physical writing surface using thermal ink. Underneath the physical writing surface is a heating layer. Once the heating layer is activated, the thermal ink disappears. Meanwhile, sensors capture a user's strokes while writing, and a computing device digitally stores the captured strokes. Therefore, there is zero-time delay or lag time between writing on the physical writing surface and its appearance. Finally, there is no need to erase any writing nor use other sheets or boards after one use because the writing is automatically erased.
