It is projected on the first sensing area S1 of the second wafer 30 receiving visible ray so that the first sensing area S1
It is less affected by the second transmission region CL2 set infrared light when receiving visible ray and penetrates film
Impact, therefore can effectively promote the penetrance of visible ray.
Additionally, due to launch the first wafer 32 of Infrared L1 with reception Infrared L1 ＇'s
Second sensing area S2 be disposed adjacent to each other and be respectively positioned on Watch glass G the second transmission region CL2 it
Under, that is the first wafer 32 and the second sensing area S2 carrying out proximity sensing function is positioned at Watch glass
Under the same little loophole (the second transmission region CL2) of G.When user operates portable electronic
During device, from the little printing opacity that can only somewhat see Watch glass G in appearance of portable electronic devices
Hole (the second transmission region CL2), and more difficult the first transmission region CL1 seeing Watch glass G.
For example, it is assumed that be arranged at the visible ray on the first transmission region CL1 of Watch glass G
Penetrating film to the penetrance of optical wavelength 550nm is 50%, is arranged at second printing opacity of Watch glass G
It is 20% and to optical wavelength that infrared light on the CL2 of region penetrates film to the penetrance of optical wavelength 550nm
The penetrance of 940nm is 85%.
When visible ray L2 is disposed through on the first transmission region CL1 of Watch glass G visible
When light penetrates film and is incident upon the first sensing area S1 of the second wafer 30, the first sensing area S1 can sense
To light luminance be about visible ray L2 brightness 50%, and can obtain bigger than prior art
Field-of-view angle and higher visible ray penetrance.
Infrared L1 sent when the first wafer 32 is disposed through Watch glass through object reflection
