AI Technical Summary
In-cell display touch panels cannot implement the Wake-On Touch (WOT) function in the Windows 11 operating system because when the host goes to sleep, the display power is turned off, the touch module's driver module loses power, and touch operations cannot be recognized.
A power conversion module, a power management module, a display touch driver module, and a control module are introduced into the driving circuit of the display touch panel. The control module sends an enable signal to the power conversion module to switch the input power of the power management module to the touch power or the display power, so that the display touch driver module can remain online and recognize touch operations after the host is in sleep mode.
It enables the touch panel to continue scanning and recognizing touch operations even after the host computer has gone into sleep mode, thus achieving WOT functionality and meeting the requirements of the Windows 11 operating system.
