Abstract
A touch display device is provided and includes a substrate, light emitting layer, encapsulation layer, a touch layer, and a touch driver inspection circuit. The touch layer includes a plurality of touch electrode units. The touch driver inspection circuit is connected to each of the touch electrode units the touch layer and is configured to monitor a touch position according to variation of a capacitance of the touch electrode units. The touch driver inspection circuit is further configured to monitor a pressure of the touch position according to variation of pressures on the touch electrode units.
