Abstract

The invention discloses a fingerprint identification module and a fingerprint identification display device. A shading layer arranged on photosensitive induction units in the fingerprint recognition module comprises first shading parts arranged above photosensitive diodes of the photosensitive induction units, and fixed potential signal lines, wherein each first shading part is electrically connected with one electrode end of the photosensitive diode below, and each first shading part is connected with the corresponding fixed potential signal line. As the fixed potential signal lines are moved to above the photosensitive diodes and the shading layer is used directly to form the fixed potential signal lines, a space-occupying connecting hole is avoided, the area taken up by the photosensitive diodes is maximized, the photocurrent produced by the photosensitive diodes during fingerprint detection is increased, and the accuracy of fingerprint detection is improved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a fingerprint recognition module, a manufacturing method thereof and a fingerprint recognition display device. Background technique [0002] With the rapid development of display technology, display panels with a fingerprint recognition function have gradually spread in people's lives. At present, in the display device, the photosensitive characteristics such as PIN junction can be used to realize the function of fingerprint identification, and in order not to affect the normal display effect of the display panel 1, that is, not to affect the aperture ratio of the display panel 1, as figure 1 As shown, the photosensitive unit 2 is generally arranged at a position corresponding to the gap between the light emitting regions R, B and G in the display panel 1, that is, the photosensitive unit 2 is arranged at a position corresponding to the non-display region. The photosensitive unit...
