Abstract

The present invention relates to an apparatus for repairing a bright point defect in a display device, and more particularly, to an apparatus for repairing a bright point defect in a display device having a uniform laser beam energy density across the entire scope of a laser radiation area. The apparatus for repairing a bright point defect according to the present invention comprises: a laser part for radiating a laser beam onto a color filter having a bright point defect; a scanner for scanning the laser beam in a radiation area of the color filter; and beam-processing surface control means for filtering and preventing the scanned laser beam from being radiated onto the color filter in an acceleration section or a deceleration section.

Description

technical field [0001] The present invention relates to a device for repairing bright spot defects of a display device, in particular, relates to a device for repairing bright point defects of a display device. The energy density of the laser beam is uniform throughout the laser beam irradiation area. Background technique [0002] Recently, a liquid crystal display device has attracted attention as a next-generation cutting-edge display device, which has low power consumption, good portability, technology-intensive, and high added value. Among such liquid crystal display devices, especially an active matrix type liquid crystal display device (including a switching element capable of switching a voltage applied to each pixel) has attracted the most attention due to its excellent resolution and video processing capability. [0003] refer to figure 1 As shown, the structure of a common liquid crystal panel 500 is that a color filter substrate as an upper substrate and a thin f...
