Abstract

A touch display panel and a touch display device including an array substrate, a light-emitting layer, an encapsulation layer, and a touch function layer are provided. The array substrate includes a first trace. The touch function layer includes a second trace. The second trace is electrically connected to the chip by a bonding end, in which the chip is integrated with functions of display control and touching control. This realizes a control of a display function and a touch function of the touch display panel or the touch display device, thereby reducing the number of chips. At the same time, the stepped structure of the edge of the encapsulation layer effectively alleviates the steep gradient between the touch function layer and the array substrate, thereby facilitating the electrical connection of the trace on the touch function layer to the trace on the array substrate.
