- the proximity/light sensor 13 is disposed in a lower base module 11 of the handheld mobile phone 10 and detects the light through an opening 14 formed through an upper base module 12 .
- the error generated by assembly of the handheld mobile phone 10 causes the detection of the proximity/light sensor 13 to be inaccurate.
- the proximity/light sensor 13 needs to be re-calibrated.
- an overlarge air gap AG between the proximity/light sensor 13 and the opening 14 of the upper base module 12 affects the performance of the proximity/light sensor.
- an overlarge diameter of the opening 14 of the upper base module 12 also significantly affects the appearance of the handheld mobile phone 10 .

- the present invention provides a handheld electronic apparatus including an upper base module.
- the upper base module includes a proximity/light sensor and a touch controller.
- the proximity/light sensor detects a distance between the proximity/light detector and an external object according to a light.
- the touch controller is coupled to the proximity/light detector for controlling a touch control action on a touch sensor of the handheld electronic apparatus.
- the touch controller includes a memory coupled to the proximity/light detector for storing a calibration parameter of the proximity/light detector.
- the memory is a non-volatile memory.

- the proximity/light sensor is disposed in the upper base module, inaccurate calibration of the proximity/light sensor due to the error caused by the assembly of the handheld electronic apparatus can be effectively avoided, which can therefore increase the calibration accuracy of the proximity/light sensor.
- FIG. 1 is a cross-sectional view of a conventional handheld mobile phone 10 .
- FIG. 2 is a cross-sectional view of a handheld electronic apparatus 20 according to one embodiment of the present invention.
- FIG. 3 illustrates a handheld electronic apparatus 100 according to one embodiment of the present invention.
- FIG. 4 illustrates the relationship between the proximity/light sensor 111 and the touch controller 112 of the embodiment of FIG. 1 .
- FIG. 5 illustrates a handheld electronic apparatus 300 according to another embodiment of the present invention.
- 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
- a printed circuit board 25 is disposed in the lower base module 21 .
- the upper base module 22 correspondingly form an opening 24 above the proximity/light sensor 231 , such that the proximity/light sensor 231 can detect whether there is an external object approaching a surface of the upper base module 22 of the handheld electronic apparatus 20 .
- the printed circuit board 25 is connected to the proximity/light sensor 231 and touch sensor 232 by a flexible circuit board 23 .
- the proximity/light sensor 231 is disposed in the upper base module 22 , the air gap between the proximity/light sensor 231 and the opening 24 can be effectively reduced. 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 upper base module 110 includes a proximity/light sensor 111 , a touch controller 112 , and a touch sensor 113 .
- 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 .
- the proximity/light sensor 111 is disposed in the upper base module 110 of the handheld electronic apparatus 100 , when the upper base module 110 of the handheld electronic apparatus 100 is assembled, the necessary calibration of the proximity/light sensor 111 can be completed at the same time.
- 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.
- touch controller 112 and the proximity/light sensor 111 may also be integrated into a single integrated circuit (IC) to reduce area needed for circuit elements.
- IC integrated circuit
- FIG. 4 illustrates the relationship between the proximity/light sensor 111 and the touch controller 112 of the embodiment of FIG. 1 .
- the touch controller 112 includes a non-volatile memory 1121 , and the proximity/light sensor 111 may be coupled to the non-volatile memory 1121 .
- the non-volatile memory 1121 is used to store setting data needed by the touch controller 112 that controls the touch action detection performed on the touch sensor 113 . 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 .
- FIG. 5 illustrates a handheld electronic apparatus 300 according to another embodiment of the present invention.
- the handheld electronic apparatus 300 includes an upper base module 310 and a lower base module 320 .
- the upper base module 310 includes a touch sensor 313 , a proximity/light sensor 311 , a touch controller 312 , and a flexible printed circuit FPC 1 .
- the touch sensor 313 may be a touch display panel which integrates touch control and display functions.
- the flexible printed circuit board FPC 1 is disposed between the touch controller 312 and the touch sensor 313 and acts as a signal transmission medium between the touch controller 312 and the touch sensor 313 .
