This paper reports an optical fingerprint structure based on an integrated microlens array. The structure is manufactured by TFT backplane technology and can be used with an OLED screen to realize full-screen fingerprint recognition. In this paper, we studied the influence of the height of the microlens, the position of the collimating layer, and the position of the sensor, and achieved an optical fingerprint recognition...
