Abstract
This disclosure provides devices, apparatuses and methods of preventing incorporation of bright defects into an image generated by a display apparatus. A display apparatus may include a chromic film that is selectively activated, with the activated regions of the chromic film being colored, light blocking regions that overlie or underlie bright defect pixels of the display apparatus. The remainder of the chromic film is colorless and light transmissive. The chromic film may be provided as a coating on a substrate of the display apparatus. The chromic film may be selectively activated by exposing regions that overlie or underlie bright defect pixels to laser radiation. The laser radiation may induce a photochemical or thermally activated reaction in the chromic film, selectively changing the irradiated regions from colorless and light transmissive to colored and light blocking.
