Abstract

The invention discloses a fingerprint recognition module group, a manufacturing method and a driving method thereof, and a display device, which belong to the field of displays. The fingerprint recognition module group comprises a substrate and a plurality of fingerprint recognition modules arranged on the substrate in an array manner, wherein each fingerprint recognition module comprises a lower electrode, an upper electrode and a light current generating unit connected between the upper electrode and the lower electrode, each light current generating unit comprises a PN junction, one end of each PN junction is connected with the corresponding upper electrode, and the other end of each PN junction is connected with the corresponding lower electrode. In this way, the module group having a fingerprint recognition function is implemented, and an OLED display panel having a fingerprint recognition function can be implemented by applying the module group to the OLED display panel.

Description

technical field [0001] The invention relates to the field of displays, in particular to a fingerprint identification module, a manufacturing method and a driving method thereof, and a display device. Background technique [0002] Due to the characteristics of high contrast ratio, thin thickness, wide viewing angle, and fast response speed, OLED displays have begun to gradually replace Liquid Crystal Displays (LCD for short). The traditional LCD can integrate the fingerprint identification function into the LCD, so as to realize the display and fingerprint identification functions at the same time. As for the OLED display, there is no OLED display integrated with the fingerprint identification function at present. Contents of the invention [0003] In order to solve the problem that there is no OLED display integrated with a fingerprint identification function at present, the embodiment of the present invention provides a fingerprint identification module, a manufacturing m...
