Abstract

The invention discloses a fingerprint module group, and the module group is attached to a non-display surface of a display panel for fingerprint recognition. The module group comprises a substrate, a wafer, and a gold thread. The wafer comprises a first surface and a second surface, which are opposite to each other. The second surface is attached to the substrate, and the gold thread is electrically connected between the wafer and the substrate. The gold thread is located between the first surface and the substrate in a direction perpendicular to the substrate. The gold thread is located between the first surface and the substrate in the direction perpendicular to the substrate, and the attaching of the first surface to the non-display surface is not disturbed, thereby enabling the first surface of the wafer to be directly attached to the non-display surface of the display panel, reducing the thickness of the module group, facilitating the design of a thin mobile terminal, and improving the user experience.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint module, a display screen and a mobile terminal. Background technique [0002] Fingerprint identification technology is a convenient and safe identification technology, which identifies the user's identity by identifying the user's fingerprint information. In recent years, the use of fingerprint identification technology on mobile terminals has also attracted more and more attention. Optical fingerprint identification is a widely used fingerprint identification method. The fingerprint module identifies fingerprint information by analyzing the light signals reflected by the valleys and ridges of the fingerprint. In order to combine the display function of the mobile terminal with the fingerprint identification function, an optical fingerprint module is often attached to the bottom of the display panel. While the display panel emits light to display...
