Abstract: A touchscreen panel is configured to accept an input touch command. The touchscreen panel includes a liquid crystal display (LCD) layer. The touchscreen panel also includes a touch sensor having a receiving element and a transmitting element, each arranged on the LCD layer. The receiving element and the transmitting element together are configured to detect an impending touch of the touch sensor via a hover system and a touch event in a touch-detecting mode. At least one of the receiving element and the transmitting element is configured to operate in a heating mode, as a heating element, when the impending touch of the touch sensor is not detected. The resultant heating element generates a heat energy input to the LCD layer and accelerates responsiveness of the LCD layer to the touch event. A method of controlling a touchscreen panel is also disclosed.
