Abstract: Embodiments of the disclosure relate, generally, to touch panel security, and more specifically, to using one or more security features present at one or more electrodes of a sensor module of a touch panel. Embodiments of security features may affect the capacitive coupling at a node of a sensor in a manner detectable by a microcontroller or other logic circuitry, and the location of the security features may provide a basis for an identifier usable to identify a touch panel to a host device with which the touch panel attempts to communicate.

Abstract: A display control device for controlling a display apparatus is provided. The display apparatus includes a touch panel and is for displaying an image signal of a computer host. The display control device includes a touch panel controller and a screen controller. The touch panel controller controls the touch panel to perform touch sensing and accordingly generates a touch control signal. The screen controller controls the display apparatus to operate between an adjustment mode and a display mode according a mode signal. When the display apparatus operates in the adjustment mode, the screen controller performs on-screen display (OSD) control according to the touch control signal to adjust the display apparatus. When the display apparatus operates in the display mode, the touch control signal is transmitted to the computer host to control the computer host.
