IN-CELL TOUCH SCREEN PANEL, METHOD OF DRIVING IN-CELL TOUCH SCREEN PANEL, AND DISPLAY DEVICE

摘要

An in-cell touch screen panel is disclosed. The in-cell touch screen panel includes a capacitive touch control circuit, a control module and a dermatoglyphics identification circuit. The capacitive touch control circuit is configured to determine a touch control position. The control module is configured to determine a dermatoglyphics scan region on basis of the touch control position, and send a dermatoglyphics scan signal to the dermatoglyphics identification circuit. The dermatoglyphics identification circuit is configured to scan the dermatoglyphics in the dermatoglyphics scan region to produce identification signals responsive to the dermatoglyphics scan signals, and send the identification signals to the control module. The control module processes the identification signals. A method of driving the in-cell touch screen panel and a display apparatus comprising the in-cell touch screen panel are further disclosed.
