Abstract
Official abstract text for this publication.
The present invention provides a method and system for repairing flat panel display, which repairing hot pixels of the flat panel display by femtosecond laser. The flat panel display comprises a LCD module and a color filter disposed on the top of the LCD module, wherein the surface of the color filter corresponding to the LCD module further has a color photoresist layer. The femtosecond laser is projected onto the color photoresist layer corresponding to the hot pixels such that a phenomenon of nonlinear multiple photons absorption can be occurred to change property of the color photoresist layer so as to transform the hot pixels into dead pixels.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for repairing flat panel display, comprising the steps of: providing a flat panel display having at least one hot pixel and being configured with a liquid crystal module and a filter in a manner that the filter is formed with a photoresist layer while being disposed on the liquid crystal module; and projecting a femtosecond laser beam on the photoresist layer at positions corresponding to the at least one hot pixel for blackening the corresponding…
