Abstract
The present disclosure relates to an input and output device, and more particularly to a touch display device. The touch display device comprises a display panel, a touch controller, and a power supplier. The display panel performs an image display operation in a display state. The touch controller performs a touch controlling operation in a working state. The power supplier is coupled to the touch controller and provides an operation voltage to the touch controller. When the display panel is in a non-display state, the power supplier is enabled not to provide the operation voltage to the touch controller such that the touch controller comes in a non-working state.
