Abstract: An electronic device is disclosed. The electronic device includes a substrate, a plurality of color filters disposed on the substrate, an optical film disposed on the plurality of color filter, and a defect disposed between the substrate and the optical film. The optical film has a first base, a protective layer on the first base, and a second base between the first base and the protective layer and having a first processed area. In a top view of the electronic device, the first processed area corresponds to the defect and at least partially overlaps at least two color filters.

Abstract: An optical wavefront testing system includes a light source, an image capturing unit and a processing unit. The image capturing unit includes a lens array and a sensor module that is configured to detect light rays passing through an optical element and the lens array. The processing unit controls the sensor module to detect the light rays under a plurality exposure conditions for generating a plurality of images each including a plurality of light spots, obtains a plurality of light spot datasets corresponding to the light spots and each including a plurality of pixel coordinate sets and a plurality of pixel values, and obtains wavefront information associated with the light spots based on the light spot datasets of at least two of the images.
