Benefits of technology
The patent application describes a display panel and device that includes a first substrate with a touch electrode layer and signal transmission circuits. The signal transmission circuits include a first circuit and a second circuit, as well as a control signal circuit connected to the control chip. The second circuit and control signal circuit are located on the same layer, eliminating the need for a hole for electrical connection between the two circuits. This reduces the density of holes in the circuit region and improves its strength, solving the issue of easy breakage in the prior art display panel.
Problems solved by technology
Therefore, it is necessary to provide a hole in the circuit region, resulting in a higher density of holes in the circuit region, which in turn cause the circuit region to be easily broken.
That is, the existing display panel has a technical problem that one needs to provide holes for electrical connection between signal transmission circuits and control signal circuits in the circuit region, however it causes the circuit region to be easily broken.

Abstract
The invention provides a display panel and a display device. An array substrate of the display panel includes signal transmission circuits and a control signal circuit. The signal transmission circuits include a first signal transmission circuit and a second signal transmission circuit in the circuit region. The second signal transmission circuit and the control signal circuit are disposed at the same layer. Therefore, there is no need to provide a hole for electrical connection between second signal transmission circuit and control signal circuit in the circuit region. The density of the holes in the circuit region is reduced.
Description
BACKGROUND OF THE INVENTIONField of Invention[0001]The present invention relates to a liquid crystal display and more particularly to a display panel and a display device.Description of Prior Art[0002]At present, the self-capacitive display panel multiplexes the common electrode units into touch units by dividing the common electrode layer in the display panel into a plurality of common electrode units and by time-sharing driving, thereby further reducing the thickness of the display panel. At the same time, it also improves production efficiency and reduces production costs.[0003]In the above display panel, the array substrate includes, in addition to the common electrode layer, a signal transmission circuit layer disposed in a different layer from the common electrode layer, and the signal transmission circuit layer includes a plurality of signal transmission circuits electrically connected to the common electrode units to provide a driving signal for each common electrode unit.[0...
