Definitions

  • an angle of the light beam transmitting through the each of the plurality of light-transmitting portions and reaching the one of the plurality of photosensitive elements corresponding to the each of the plurality of light-guiding units relative a plane substantially perpendicular to the through-hole can be within a range of about 88.8°-90°.
  • each of the plurality of light-transmitting portions comprises an optical fiber.
  • FIG. 13B is a schematic diagram of a case where the thickness of the light-guiding portion of FIG. 13A increases.
  • a total of two fingerprint identification devices 01 can be arranged in a display apparatus. Whereas a firstfingerprint identification device can be employed to receive light beams reflected from lights emitted from the display apparatus, a second fingerprint identification device can be employed to receive light beams from an environment.
  • it can be configured such that no data lines, transistors, capacitors, or other electronic components are not arranged in the portion of the display panel 200 that positionally correspond to the photosensitive element 11 in the first fingerprint identification device 100 so as to allow the lights reflected by the finger can transmit through this substantially light-transmissive portion of the display panel 200 to thereby be able to reach the photosensitive element 11 of the first fingerprint identification device 100.
  • a palmprint or a face also has its unique patterns of valleys and ridges, and can be employed for an identification process similar to the fingerprint identification process.
  • the chance of light interference between two adjacent light-transmitting portions can be further reduced, which in turn can further increase the pattern identification accuracy for the device.
  • a fingerprint identification device can have one photosensitive element corresponding to a plurality of light-transmitting portions.
  • the cross-section area of each light-transmitting portion can be reduced, and the thickness of the light-guiding layer can also be reduced accordingly.
  • a lighter-weight and thinner fingerprint identification device can be realized.
  • increasing the number and/or density of the light-transmitting portions can improve the amount of light transmission, which improves the identification accuracy.
