One of known warping in optical films detection method, is using artificial visual detection method, and it is by optics to be detected
Film is positioned on a platform, and this platform has the tool of specific warpage specification, and personnel confirm optical thin film with visual method
Whether warpage situation is located in the warpage specification of this tool, if being located in this specification, that is, judges this optical thin film as non-defective unit, instead
It, then be judged to defective products.However, the too many time can be expended with the method for this artificial visual detection, and because everyone judges mark
Accurate difference leads to testing result error.Furthermore, aforementioned tool is detected, optical thin film can only be divided into non-defective unit and not
Non-defective unit, and the actual warpage numerical value of each optical thin film cannot be obtained.
And another known warping in optical films detection method, please coordinate with reference to shown in Fig. 1, Fig. 1 sticks up for known Polarizer
The schematic diagram of bent detection method, Polarizer 2 to be detected is statically placed in the surface 11 of a platform 1 by it, treats that Polarizer 2 is in stable state
Afterwards, personnel will sequentially measure angle 1, angle 2 22, angle 3 23 and the angle 4 24 of Polarizer 2 with respect to platform 1 using rule 3
The depth of camber H on surface 11, to obtain the actual warpage numerical value of this Polarizer 2 to be detected, and then whether the warpage of Polarizer 2 accords with
Close warpage specification.Although, the method can obtain the actual warpage numerical value of Polarizer 2, and shortcoming is same as aforementioned artificial visual detection
Method, also can expend the too many time, and because the difference of everyone's criterion leads to testing result error.
