| titleOfInvention | Optical sensor module including means for improving fingerprint recognition rate of optical fingerprint sensor |
| abstract | The present invention relates to an optical sensor module (000), comprising: a light emitting panel (100) for irradiating light; A polarizer 200 positioned on one surface of the self-luminous panel 100; A window 300 disposed on one surface of the polarizer 200; A window protection film 400 positioned on at least one surface of the window 300; A fingerprint sensor unit 500 positioned on the other surface of the surface of the polarizing plate 200 of the self-luminous panel 100 and sensing light reflected from the fingerprint of the user by being irradiated from the self-luminous panel 100; And a) the mutual angle θ between the absorption axis 201 of the polarizer 200 and the slow axis 401 of the window protective film 400 is -15 ° to 15 ° or 75 ° to 105 °. Improve the fingerprint reflectivity by improving the specular reflectance by adjusting; b) a λ / 4 phase difference 600 layer is further included between the polarizer 200 and the window protective film 400 so that the specular reflectance of the absorption axis 201 of the polarizer 200 and the window protective film 400 may be included. It is possible to improve the fingerprint recognition rate of the fingerprint sensor without additional mutual angle adjustment when used with additional means such as increasing the amount of light irradiation of the self-luminous panel included together by maintaining a constant level irrespective of the mutual angle between the slow axes 401. It features. |
