Abstract
A touch display apparatus includes a touch driver and a display driver. The touch driver outputs touch signals to drive a touch panel. The display driver outputs scan signals to drive a display panel. A display driver has a plurality of shift registers, and each of the plurality of shift registers includes a pull-up unit, a driving unit, a pull-down unit and a holding unit. The pull-up unit is electrically connected to a driving node for outputting a driving voltage. The driving unit is electrically connected to the driving node for outputting a first scan signal according to a clock. A pull-down unit is electrically connected to the driving node and the output terminal, for pulling down the voltage level of the driving voltage and the first scan signal, respectively. The holding unit is electrically connected to the driving node.
