  • FIG. 2 is a cross-sectional view of a handheld electronic apparatus 20 according to one embodiment of the present invention.
  • the handheld electronic apparatus 20 includes an upper base module 22 and a lower base module 21 .
  • a proximity/light sensor 231 , a touch controller 232 and a touch sensor 233 are disposed in the upper base module 22

Therefore, interferences caused by diffraction, refraction and/or scattering of light detected by the proximity/light sensor 231 can also be significantly reduced. In addition, a diameter of the opening 24 can also be effectively reduced, which results in a more aesthetic appearance of the handheld electronic apparatus 20 .
  • FIG. 3 illustrates a handheld electronic apparatus 100 according to one embodiment of the present invention.
  • the handheld electronic apparatus 100 may be, for example, a handheld mobile phone.
  • the handheld electronic apparatus 100 includes an upper base module 110 .

  • the proximity/light sensor 111 is used to detect a distance between the proximity/light sensor and an external object according to a light.
  • the upper base module 110 correspondingly forms an opening above the proximity/light sensor 111 , and the proximity/light sensor 111 can detect the distance between the external object and the proximity/light sensor 111 by detecting a luminance of the light through the opening.
  • the proximity/light sensor 111 may detect the distance between the user's face and the upper base module 110 according to the decreased light luminance.
  • the proximity/light sensor 111 , the touch controller 112 , and the touch sensor 113 are commonly disposed in the upper base module 110 of the handheld electronic apparatus 100 . That is, the proximity/light sensor 111 may approach closer to the position of the upper base module 110 where the user contacts, the air gap of the opening through which the proximity/light sensor 111 receives light may also be effectively reduced, thus reducing the interferences caused by reflection of light and hence increasing the accuracy of the proximity/light sensor 111 . Because the distance between the proximity/light sensor 111 and the position of the upper base module 110 where the user contacts, the diameter of the opening may also be effectively reduced, which results in a more aesthetic appearance of the handheld electronic apparatus 20 .

  • calibration of the proximity/light sensor 111 is independent of the assembly of parts other than the upper base module 110 of the handheld electronic apparatus 100 (e.g. the lower base module). That is, the error caused by overall assembly of the handheld electronic apparatus 100 does not affect the accuracy of the calibration of the proximity/light sensor 111 . As such, re-assembly of the electronic apparatus 100 does not affect the detection accuracy of the proximity/light sensor 111 , and does not require re-calibration of the proximity/light sensor 111 .
  • the calibration of the proximity/light sensor 111 may be conducted together with calibration of the touch controller 112 , without separately calibrating the proximate/light detector 111 and the touch controller 112 , thus reducing the complexity of production process.

If the memory space of the non-volatile memory 1121 is not fully used, the spare memory space can be used to store calibration parameters needed by the proximity/light sensor 111 during calibration.
  • the calibration parameters may, for example, include the distance between the touch sensor 112 and the proximity/light sensor 111 .
  • the spare memory space of the existing non-volatile memory 1121 of the touch controller 112 to store the calibration parameters of the proximity/light sensor 111 may also use spare space of another memory of the touch controller 112 to store the calibration parameters of the proximity/light sensor 111 instead of using the non-volatile memory 1121 .
  • the memory storing the calibration parameters of the proximity/light sensor 111 and the proximity/light sensor 111 are disposed in the upper base module 110 , when the proximity/light sensor 111 needs to be calibrated during repairing of the handheld electronic apparatus 100 , the calibration data of the proximity/light sensor 111 can be readily obtained to accomplish the calibration of the proximity/light sensor 111 .
