The invention discloses a touch display panel and a touch display device. The touch display panel comprises a first base plate and a second base plate. The first base plate comprises a first display area and a first step area. The first step area is an area extending outwards from the first display area in the plane in which the first base plate is. The second base plate is arranged opposite to the first base plate. The second base plate comprises a second display area and a second step area. The second step area is an area extending outwards from the second display area in the plane in which the second base plate is. The first display area is opposite to the second display area. At least a part of the first step area and a part of the second step area are in staggered arrangement. Through adoption of the touch display panel, the technical problem that the first step area and the second step area block each other in binding of a chip and a flexible printed circuit board is solved, so that the binding of the chip and the flexible printed circuit board is convenient, the production efficiency is improved, and the production difficulty is lowered.
Description
technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display panel and a touch display device. Background technique [0002] Currently, in the field of display panels, display panels with touch functions have become more and more mainstream display products, and various integration methods of display panels and touch panels have emerged, which can be described as various, such as incell, Out-of-the-box (oncell) and plug-in. On the other hand, if classified from the working principle, the display panel with touch function can be roughly divided into capacitive, resistive, infrared and so on. Among them, the capacitive touch display panel mainly includes two types: self-capacitive and mutual-capacitive. Each type of touch display panel has its own advantages and disadvantages. The touch display panel based on self-capacitance usually arranges the electrodes used for touch control inside the outer substrate of...
