Embodiment Construction

[0045] In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

[0046] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only, and do not mean the only implementation.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same mea...

Abstract

The invention relates to a touch module, a display screen and display device. The touch module comprises a first conductive layer, a second conductive layer, the first conductive layer is divided intoa plurality of bridging lines and first electrode lines, the second conductive layer comprises a plurality of driving electrodes arranged along a first direction and a plurality of induction electrodes arranged along a second direction, and the driving electrodes and the induction electrodes are mutually crossed; at the intersection position, the induction electrode is disconnected or the drivingelectrode is disconnected. The driving electrodes and the sensing electrodes can be used for a touch function or a fingerprint recognition function. The first electrode lines in the first conductivelayer and the driving electrodes and / or the induction electrodes in the second conductive layer form a parallel plate capacitor, the parallel plate capacitor can be used for a touch control function or a fingerprint identification function, and therefore integration of the fingerprint identification function and the touch control function is achieved.

Description

Technical field [0001] The invention relates to the field of display technology, in particular to a touch module, a display screen and a display device. Background technique [0002] With the development of touch technology and display technology, touch display devices have been sought after by more and more people. Taking common touch smart mobile terminals as an example, their higher and higher screen-to-body ratios are designed for users Brings a more extreme visual experience than ever before. However, while smart mobile terminals have increased their screen-to-body ratio, the space left for users for fingerprint recognition for security authentication is getting smaller and smaller. [0003] In order to allow the terminal to achieve a higher screen-to-body ratio, some terminal manufacturers set the fingerprint unlocking on the back of the fuselage. The rear-mounted fingerprint unlocking will affect the appearance of the terminal back cover. In order to solve the realization of...
