Problems solved by technology

In addition, as China Taiwan Publication No. 200829977 discloses a method and device for repairing a liquid crystal display panel, which uses a continuous wave (CW) or pulse (Pulse) laser with a wavelength of 400-490 nm or a frequency of > The femtosecond laser with a wavelength of 10MHz and a wavelength of 450nm is repaired using the RGB linear absorption range, which needs to be processed by the transistor surface of the liquid crystal display. If it is repaired from the color filter surface, the polarizing film will be easily damaged

Abstract

The invention provides a method and a system for repairing a flat panel display, which are mainly used for repairing the flat panel display with bright spot defects by femtosecond laser. The flat panel display is provided with a driving module and an optical filter arranged on the driving module. A panel of the flat panel display, which corresponds to the driving module, is provided with a photoresist layer. In the invention, the femtosecond laser is irradiated onto the photoresist layer of corresponding bright spots, so that the photoresist layer generates a nonlinear multiphoton absorption effect to be modified, and thus, the bright spots are converted into dark spots.

Description

technical field [0001] The invention relates to a repair technology, in particular to a repair method and system for a flat panel display. Background technique [0002] The liquid crystal display is a non-active light-emitting element, and its color display must provide a light source through the backlight module, cooperate with the driving circuit and the liquid crystal control to form a gray-scale brightness display, and pass through the red (R), green (G) and blue color of the filter. Color (B) The photoresist layer gives each pixel a specific color, and pixels of different colors form a color picture. If there is a defect in the panel, the pixel in the display will not be able to correctly display the required color, resulting in bright or dark spots. Among them, the bright spots are particularly obvious to monitor users, so the number of bright spots is also one of the elements for panel grade evaluation one. [0003] In the prior art, for example: the repairing metho...
