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

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

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.

Display system and panel driving circuit

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.
