| titleOfInvention | Biometric imaging device and method for manufacturing biometric imaging device |
| abstract | A biometric imaging device (100) configured to capture an image of an object (102) in contact with an outer surface (104) of the imaging device, the biometric imaging device comprising: an at least partially transparent display panel (106) comprising a repeating transmission pattern defined by an array of display cell boxes (108), each display cell box having the same transmission pattern; an image sensor (110) comprising a photodetector pixel array (111) arranged below the display panel; and a collimator layer (112) arranged between the display panel and the image sensor, the collimator layer comprising a plurality of first collimating structures (114) having a first collimator opening size and a plurality of second collimating structures (116) having a second collimator opening size, the second collimator opening size being different from the first collimator opening size, wherein the respective collimator opening sizes and relative positions of the first and second collimating structures with respect to the display unit box are based on a transmission pattern of the display unit box. |
