Embodiment Construction

[0047] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0048] see figure 2 , the laser light is fully irradiated to the color filter 532 that is confirmed to have bright spot pixel defects, and at the same time, the laser scans on the color filter in a zigzag manner along the arrow, so that the color filter 532 and the glass 531 (see figure 1 ) to form a gap G. Of course, the gap G may also be formed in the thickness direction of the color filter 532 in addition to being formed between the color filter 532 and the glass.

[0049] Subsequently, if image 3 As shown, the laser is irradiated to the black matrix 533 while scanning the laser on the black matrix to decompose the black matrix 533 . The decomposed black matrix 533 is introduced into the gap G. Referring to FIG.

[0050] Finally, if Figure 4 As shown, the laser is irradiated to the black matrix 533 and the color filter 532, and the la...

Abstract

Disclosed herein is a method of repairing a bright pixel defect of a display device that is capable of effectively repairing a bright pixel defect of a display device using laser. When the display device includes black matrices, the method includes forming a gap at a color filter having a bright pixel defect or between the color filter and a glass using laser, and decomposing black matrices neighboring to the color filter using laser.

Description

technical field [0001] The present invention relates to a method for repairing bright pixel defects of a display device, and more particularly to a method for repairing bright pixel defects of a display device that can effectively repair bright pixel defects of a display device using laser light. Background technique [0002] In recent years, liquid crystal displays have been in the center of attention as next-generation high-tech display devices with low power consumption and high portability, technology density, and high added value. Among them, an active matrix type liquid crystal display, which includes a switching device for switching a voltage applied to each pixel, has attracted the most attention for its high resolution and high-quality motion picture realization. [0003] see figure 1 , the liquid crystal panel 500 is constructed in a structure in which a color filter substrate 530 which is an upper substrate and a thin film transistor (TFT) array substrate 510 whi...
