Patent ID: 7755596

Claim:
An electronic device comprising: a display device defining a display surface along a side thereof for display; a light source installable in said display device for illuminating said display surface of said display device for said display; a driving device installable in said display device beside said light source for driving illumination of said light source, said driving device comprising a circuit board and electronic components mounted on a first surface of said circuit board to function for said driving device, said circuit board disposed in said display device by means of a selective surface of said circuit board facing said display surface of said display device; and a light sensor module electrically connectable to said circuit board on said first surface of said circuit board beside said electronic components, said light sensor module comprising a light sensor chip packaged therein and able to sense external light outside said display device through said display surface with help of said selective surface of said circuit board; wherein said selective surface of said circuit board is a second surface of said circuit board opposite to said first surface and said light sensor chip senses said external light via a light sensor hole defined in said circuit board communicating said first surface with said second surface of said circuit board when said light sensor module is mounted on said first surface of said circuit board.
