Abstract

The invention discloses a display module, a manufacturing method of the display module and a display device. The display module comprises: a display module, fingerprint recognition assembly, the display module comprises a first electrode, an insulating layer, a semiconductor device and a second electrode which are stacked in the thickness direction of the display module, the insulating layer is positioned on the first electrode; the semiconductor device is located on one side of the insulating layer away from the first electrode, wherein the second electrode is located at one side, deviating from the insulating layer, of the semiconductor device, the insulating layer is provided with a first through hole and a first via hole located at the peripheral side of the first through hole, the first through hole penetrates through the insulating layer, and at least part of the semiconductor device is located in the first through hole and connected with the first electrode through the first through hole; the light absorption part and the semiconductor device are arranged on the same layer and made of the same material, at least part of the light absorption part is located in the first via hole, and the light absorption part is insulated from at least one of the first electrode and the second electrode. According to the embodiment of the invention, the accuracy of fingerprint recognitionby the fingerprint recognition assembly can be improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display module, a method for manufacturing the display module, and a display device. Background technique [0002] In recent years, with the continuous development of display technology, more and more display devices adopt fingerprint recognition to realize user privacy protection. When a user operates a display device with a fingerprint identification function, he only needs to touch the display screen with a finger to realize authority verification, which is simple and convenient. [0003] For a display device using optical fingerprint identification technology, when performing fingerprint identification, the light emitted by the light source is reflected into the fingerprint identification unit through the touch body (such as a finger). The fingerprint identification unit realizes fingerprint identification according to the difference in light intensity of reflected light at the positio...
