A knob on a touch panel includes a rotary wheel, a common pad, at least one sensing pad, a plurality of connectors and a conductive ring. The rotary wheel is mounted on the touch panel. The common pad is deployed on the touch panel. The at least one sensing pad is deployed on the touch panel. Each of the plurality of connectors is coupled between the rotary wheel and one pad among the at least one sensing pad and the common pad, to control each of the at least one sensing pad to be coupled to the common pad or not through the rotary wheel according to an operation of the knob. The conductive ring is deployed on a surface of the rotary wheel, to detect a touch object.

Knob on touch panel and related control method

A knob on a touch panel includes a plurality of sensing electrodes and at least one conducting wire. The at least one conducting wire is coupled between the plurality of sensing electrodes. Wherein, the plurality of sensing electrodes are separated by a plurality of gaps, and the size of a first gap among the plurality of gaps is different from the size of a second gap among the plurality of gaps.

Knob on touch panel and related control circuit

A knob apparatus includes a touch panel, a touch-sensing controller, and a knob. The touch panel has multiple touch-sensing electrodes. The touch-sensing controller is coupled to the touch-sensing electrodes of the touch panel. The touch-sensing controller detects a touch event of the touch panel through the touch-sensing electrodes. The knob has a base and a knob cap. The knob cap is pivoted on the base. The base is attached to the touch panel. Multiple conductive electrodes are disposed at different positions of the base. The touch-sensing controller detects the conductive electrodes of the base of the knob through the touch-sensing electrodes of the touch panel to learn a rotation direction of the knob cap on the base.

A touch detection method, suitable for a touch display panel including multiple sensing pads, is disclosed. The sensing pads are divided into groups and each of the groups includes at least two columns of the sensing pads. The touch detection method includes following steps. In a first mode, the sensing pads are scanned group-by-group for detecting whether a touch event occurs on a touch identified group. In a second mode, the sensing pads are scanned column-by-column to identify a touch position of the touch event.

Touch detection method and touch display device

The invention provides a touch device and a communication method thereof. The touch device includes a display panel and a controller. The controller controls the display panel to perform a display driving operation and a touch sensing operation. The controller may transmit a first wireless signal to another slave communication device via the display panel in a touch sensing period. The controller may receive a second wireless signal sent by another master communication device via the display panel in the touch sensing period. When the touch device serves as one of a master communication device and a slave communication device, a time length of the touch sensing period is a first time length. When the touch device serves as the other of the master communication device and the slave communication device, the time length of the touch sensing period is a second time length greater than the first time length.

Touch device and communication method thereof

A method for touch sensing enhancement implemented in a single chip, a single chip capable of achieving touch sensing enhancement, and a computing apparatus are introduced. The single chip is used to be coupled to a display panel with a touch sensor and a fingerprint sensor. The computing apparatus may include the display panel, the single chip, and a processing unit, wherein the single chip is coupled between the display panel and processing unit. The method includes obtaining touch sensing data by a touch sensing module disposed within the single chip and coupled to the touch sensor; obtaining fingerprint sensing data by a fingerprint sensing module disposed within the single chip and coupled to the fingerprint sensor; and generating output touch data based on the touch sensing data and the fingerprint sensing data. With the contribution of the fingerprint sensing data, touch sensing enhancement can be achieved.
