Touch control display panel and touch control display device

Abstract

The embodiment of the invention discloses a touch control display panel and a touch control display device. The touch control display panel comprises a touch control detection region and a fingerprint identification region, wherein the fingerprint identification region is located in the touch control detection region; the touch control detection region comprises multiple touch control detection units which are distributed in an array, and each touch control detection unit is connected with a driving integrated chip by virtue of an accordingly connected first signal transmission line; the fingerprint identification region comprises multiple fingerprint identification units which are distributed in an array, and each fingerprint identification unit is connected with the driving integrated chip by virtue of an accordingly connected second signal transmission line; and the driving integrated chip drives the touch control detection units and the fingerprint identification units in a time sharing way for carrying out time-sharing operation in display, touch control detection and fingerprint identification. By adopting the touch control display panel disclosed by the embodiment of the invention, a fingerprint identification device and the touch control display panel do not need to be separately prepared for integration, so that the production cost of the 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.

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, in order to allow the user to perform related operations while watching the screen, a touch display panel is used. The touch display panel is one of the important carriers for integrating 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, so as to perform related operations. With the development of information security technology, users usually need to perform security authentication through fingerprint recognition when performing certain operations on touch display devices (such as operations involving transfer, payment, etc.), so as to improve inf...

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
