Between further include the film layer structures such as glass cover-plate, optical cement, polaroid, color membrane substrates, glass cover-plate general thickness 550um-
1100um, more commonly used with a thickness of 650um, optical cement general thickness is 100um-200um, it also is contemplated that mould group is thinned in client
100um is sought, polaroid takes 77um, and the thickness of color membrane substrates takes 125um, therefore the general main body, that is, finger C that touches is to imaging
The vertical range W in hole 50 is about 950um, and the vertical range X of sensor devices 401 to imaging hole 50 can use 10um, can acquire and treat as
As the aperture in hole 50When, the width V of sensor devices 401 is about 6.3um, the aperture of imaging hole 50When, sense
The width V of optical device 401 is about 7.3um, and sensor devices 401 are in order to be hidden in the lower section of the first light shielding part 3011 it is not recommended that doing too
