Problems solved by technology

However, due to the use of the silicon substrate as the substrate and the chip preparation process and parameters, the cost of the preparation process is too high; on the other hand, the silicon substrate is a non-transparent material. If it is placed on the touch The display area of ​​the display panel will affect the normal display of the screen, which is not conducive to the integration of the fingerprint recognition device and the touch display panel. If it is placed in the frame area of ​​the touch display panel, the non-display area of ​​the touch display panel will be increased. the area of

Abstract

A touch control display panel. A common electrode layer is shared by a touch detection electrode and a fingerprint identification electrode; a pixel electrode serving as a driving electrode layer conducts capacitive coupling on the fingerprint identification electrode; on this basis, a time-sharing operation for displaying, touch detection and fingerprint identification is conducted. The fingerprint identification device and the touch control display panel do not need to be separately prepared for integration, and fingerprint identification and detection can be realized by utilizing the existing layer structure of the touch control display panel, so that the production cost of a touch control display device can be effectively saved, and the effect of integration of the fingerprint identification device and the touch control display panel is achieved. The touch control display device, comprising the touch control display panel.

Description

Technical field [0001] The present invention relates to liquid crystal display technology, in particular to a touch display panel and a touch display device. Background technique [0002] In the display device, a touch display panel is used in order to allow the user to perform related operations while watching the screen. The touch display panel is one of the important carriers for the integration of input / output terminals. By measuring the coordinate position of the touch point on the touch display panel, the user's intention can be known according to the display content (such as interface graphics) corresponding to the coordinate position on the touch display panel, and related operations can be performed. With the development of information security technology, when users perform certain operations (such as operations involving transfers, payment, etc.) on the touch display device, they usually need to perform security authentication through fingerprint recognition to improv...
