A touch detection circuitry includes an analog-to-digital converter (ADC), a controller, and a packet generator. The ADC is arranged to convert touch signals of a touch panel from analog form into digital form. The controller is electrically connected to the ADC, and is configured to calculate at least one coordinate point, at least one touch event type, and at least one touch size respectively corresponding to at least one touch event on the touch panel based on the touch signals. The packet generator is electrically connected to the controller, and is configured to encapsulate the at least one coordinate point, the at least one touch event type, and the at least one touch size into a touch data packet.

A resetting system includes a driver that controls a touchscreen, the driver including a driver communication interface that defines a bus for transferring a transfer signal; and an on-screen display (OSD) device that generates an OSD signal representing a predetermined reset image in response to a predetermined event, the OSD signal superimposing over pixels and graphics data to be rendered on the touchscreen; and a host that transfers the transfer signal to or from the driver, the host including a host communication interface that defines the bus for transferring the transfer signal to or from the driver.

Resetting system and method

A touch display apparatus is disclosed, which includes a touch display panel and a driving circuit coupled to the touch display panel. The touch display panel is configured for display and touch sensing, and includes plural touch sensing pads. The driving circuit is configured to provide a voltage signal with a test pattern to the touch sensing pads, and is configured to determine whether an open circuit or a short circuit exists in the touch display panel from a detected signal in response to the voltage signal.

Touch display apparatus, driving circuit and method for automatic defect detection

A knob device is applicable to a touch panel. The touch panel includes a plurality of panel sensors. The knob device includes a knob cover, a sensing pad, a compensation sensor and a switch. The sensing pad is arranged between the knob cover and the touch panel. The switch is configured to selectively connect the sensing pad to the compensation sensor. When a move event of the knob device occurs, the switch is turned on and the sensing pad is electrically connected to the compensate sensor through the switch, such that a feedback loop is generated by the sensing pad, the compensation sensor and the touch panel to change a quantity of electric charge of at least one of the plurality of panel sensors. When a touch and rotation event of the knob device occurs, a location of the sensing pad controls a rotation sensing signal.
