Embodiment Construction

[0048] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and understandable, the specific implementation manners of the present application will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, the present application can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific implementation disclosed below.

[0049] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" an...

Abstract

The invention relates to a fingerprint recognition module, a display module and a display terminal. The fingerprint recognition module comprises a first substrate, a capacitance sensing layer, a second substrate and an anti-static layer. The capacitive sensing layer at least partially covers the surface of the first substrate. The capacitance sensing layer comprises a plurality of capacitance poleplates arranged in an array mode. The second substrate is arranged on the side, away from the first substrate, of the capacitance sensing layer. And the anti-static layer covers one side, far away from the capacitance sensing layer, of the second substrate and is used for being in contact with surface tissues of a human body. The capacitance sensing layer is clamped between the first substrate and the second substrate, so that the whole cover plate can easily realize a higher fingerprint recognition rate under the condition that the strength of the whole cover plate is enough. Meanwhile, thestatic electricity brought by human body surface layer tissues is isolated through the anti-static layer, and the problem that the capacitance sensing layer is out of order and even a circuit is burntout due to the influence of the static electricity is prevented.

Description

technical field [0001] The invention relates to the technical field of fingerprint sensing, in particular to a fingerprint recognition module, a display module and a display terminal. Background technique [0002] Due to its convenience and safety, fingerprint recognition has been used more and more in social development, especially on various display devices such as mobile phones, and it also puts forward higher and higher requirements. As the top and bottom bezel areas of the bezel shrink (and possibly disappear entirely), the fingerprint sensor will need to be placed within the display area, and doing so will require some extremely difficult engineering challenges to overcome. One of the challenges is to be able to reliably scan the fingerprint through the cover glass and achieve the resolution needed to resolve the tiny bumps and valleys in the fingerprint image. Capacitive fingerprint recognition technology can penetrate the maximum thickness of about 300-400 microns (...
