Abstract
A touch display includes a plurality of pixels, a plurality of scan lines, a plurality of data lines, a plurality of first conducting layers, and a plurality of third conducting layers. The plurality of scan lines are coupled to the plurality of pixels. The plurality of data lines are coupled to the plurality of pixels and the plurality of first conducting layers to provide a touch driving signal. Each first conducting layer of the plurality of first conducting layers is configured to receive the touch driving signal. The plurality of third conducting layers is configured to output a touch sensing signal according to the touch driving signals outputted by the plurality of first conducting layers.
