Abstract
A polarizing film inspection device includes a jig on which a display device including a polarizing film and a display panel is seated, a polarizing filter disposed on an upper portion of an edge of the polarizing film and having a polarization angle different from a polarization angle of the polarizing film, a transmission lighting disposed on a lower portion of the edge of the polarizing film and emitting light toward the edge of the polarizing film, a camera disposed on an upper portion of the polarizing filter, and a control unit which determines whether the polarizing film is defective by analyzing an image captured by the camera.

A polarizing film inspection device comprising:
- a jig on which a display device comprising a polarizing film and a display panel is seated;
- a polarizing filter disposed on an upper portion of an edge of the polarizing film and having a polarization angle different from a polarization angle of the polarizing film;
- a transmission lighting disposed on a lower portion of the edge of the polarizing film and emitting light toward the edge of the polarizing film;
- a camera disposed on an upper portion of the polarizing filter;
- and
- a control unit which determines whether the polarizing film is defective or not by analyzing an image captured by the camera.
A polarizing film inspection method comprising:
- seating a display device comprising a polarizing film and a display panel on a jig;
- aligning a camera and a transmission lighting;
- adjusting a focus of the camera onto an interface between the polarizing film and the display panel;
- passing light emitted from the transmission lighting through the polarizing film and a polarizing filter and receiving the light by the camera;
- and
- determining, by a control unit, whether the polarizing film is defective by analyzing the light received by the camera.
An electronic device comprising:
- a display device which is inspected by a polarizing film inspection device,
- wherein the polarizing film inspection device comprises:
- a jig on which a display device comprising a polarizing film and a display panel is seated;
- a polarizing filter disposed on an upper portion of an edge of the polarizing film and having a polarization angle different from a polarization angle of the polarizing film;
- a transmission lighting disposed on a lower portion of the edge of the polarizing film and emitting light toward the edge of the polarizing film;
