  • Audible noise suppression in touch display panel
    Patent number: 11194424
    Abstract: The driving apparatus for driving a touch display panel includes a first voltage generating circuit configured to generate a common reference voltage, a second voltage generating circuit configured to generate a touch driving signal, and a control circuit configured to generate a switching signal. The switching signal is at the first voltage level during display periods for providing the common reference voltage to the touch display panel. The switching signal is at the second voltage level during touch periods for providing the touch driving signal to the touch display panel. A first touch display period includes a first display period a first touch period adjacent to the first display period. A second touch display period includes a second display period and a second touch period adjacent to the second display period. The first touch display period and the second touch display period are different in time length.
    Type: Grant
