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 touch sensing apparatus includes a panel with touch detection function and a touch detection circuitry. The touch detection circuitry is coupled to the panel, and is configured to detect a touch operation on the panel, record an error event of the touch sensing apparatus, and write the error event into an external storage medium via a data transmission interface thereof.

Touch sensing apparatus, electronic device and touch operation recording method thereof

The display system includes an automotive system, a display panel, and a panel driving circuit. The panel driving circuit receives a frame from the automotive system and determines if a panel error with respect to the display panel occurs. If the panel error occurs, the panel driving circuit replaces a portion of the frame with an error icon to generate a prompt frame, and transmit the prompt frame to the display panel. If the panel error does not occur, the panel driving circuit transmits the frame to the display panel.
