Abstract

The present invention discloses anti-aliasing imaging element, photosensitive module and display module preparation methods. The anti-aliasing imaging element preparation method comprises: forming a light-absorbing layer and a transparent supporting layer that are alternately arranged in a stacked manner on a carrier, wherein the light-absorbing layer comprises a plurality of light-absorbing blocks arranged at intervals, and a region corresponding to the interval between the light-absorbing blocks is a first light-transmitting region. The photosensitive module preparation method comprises: providing a photosensitive device and an anti-aliasing element prepared by the anti-aliasing imaging element preparation method, and fixing the anti-aliasing imaging element on the photosensitive device.The display module manufacturing method comprises: providing a display device and the photosensitive module prepared by the photosensitive module preparation method, and assembling the photosensitivemodule and the display device.

Description

technical field [0001] The invention relates to a preparation method of an anti-aliasing imaging element, a photosensitive module and a display module for sensing biometric information. Background technique [0002] At present, biometric information sensors, especially fingerprint recognition sensors, have gradually become standard components of electronic products such as mobile terminals. Since the optical fingerprint recognition sensor has a stronger penetration capability than the capacitive fingerprint recognition sensor, an optical fingerprint recognition module applied to a mobile terminal has been proposed. Such as figure 1 As shown, the optical fingerprint identification module includes an optical fingerprint sensor 400 and a light source 402 . Wherein, the optical fingerprint sensor 400 is disposed under the protective cover 401 of the mobile terminal. The light source 402 is disposed adjacent to one side of the optical fingerprint recognition sensor 400 . When...
