Handheld electronic apparatus

Abstract

A handheld electronic apparatus including an upper base module is provided. 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.

What is claimed is: 
     
       1. A handheld electronic apparatus comprising:
 an upper base module, comprising: 
 a proximity/light sensor detecting a distance between the proximity/light sensor and an external object according to a light, wherein an opening is formed above the proximity/light sensor; and 
 a touch controller coupled to the proximity/light sensor for controlling a touch control action on a touch sensor of the handheld electronic apparatus, wherein the touch controller comprises a memory coupled to the proximity/light sensor for storing a calibration parameter of the proximity/light sensor, and a calibration of the proximity/light sensor is conducted together with a calibration of the touch controller; and 
 a lower base module, wherein the upper base module and the lower base module are overlapped. 
 
     
     
       2. The handheld electronic apparatus according to  claim 1 , wherein the memory is a non-volatile memory. 
     
     
       3. The handheld electronic apparatus according to  claim 1 , wherein the lower base module comprises a printed circuit board coupled to the proximity/light sensor and the touch controller. 
     
     
       4. The handheld electronic apparatus according to  claim 1 , further comprising a flexible printed circuit board disposed between the touch controller and the touch sensor, and the flexible printed circuit board acting as a signal transmission medium between the touch controller and the touch sensor, wherein the proximity/light sensor is disposed on the flexible printed circuit board and the proximity/light sensor is coupled to the touch controller through the flexible printed circuit board. 
     
     
       5. The handheld electronic apparatus according to  claim 4 , wherein the printed circuit board is coupled to the touch controller and the proximity/light sensor through the flexible printed circuit board.
