Embodiment Construction

[0042] Please refer to figure 2 , figure 2 is a schematic illustration of a machine 20 of the present invention. The machine 20 of the present invention is used to repair bright spots on a display panel 26 . The machine 20 comprises a first robotic arm 21 , a working platform 22 and a laser generating device 24 . The first automatic arm 21 moves the display panel 26 to the working platform 22 . Wherein, the first automatic arm 21 has two first vacuum chucks 211 , which are adsorbed on the lower surface 261 of the display panel 30 by the first vacuum chucks 211 , so that the first automatic arm 21 can transport the display panel 26 .

[0043] Moreover, the working platform 22 is used for erecting the display panel 26 thereon. Wherein, the working platform 22 may have two adsorption components 221 , and the adsorption components 221 are disposed below the working platform 22 . The display panel 26 from the first automatic arm 21 can be adsorbed on the upper surface 262 of...

Abstract

The machine includes working platform and laser creation device. The working platform possesses at least one adsorbing mechanism. Being setup below the working platform, the adsorbing mechanism is in use for adsorbing up surface of display faceplate. Being setup below the working platform, laser creation device can generate laser to display faceplate in order to repair bright spot on display faceplate.

Description

technical field [0001] The invention relates to a method and its machine for repairing a display panel, in particular to a method and its machine for repairing a bright spot of a display panel. Background technique [0002] Currently, in the liquid crystal display panel (LCD), the repair method for darkening the bright spots is to put the voltage of the bright spots in a high voltage state, so that light cannot penetrate, thereby achieving the effect of shading. In order to make the position of the above-mentioned bright spot in a high voltage state, the pixel electrode substrate in the display panel can generally be irradiated with laser light, so that the relative position of the above-mentioned bright spot is in a high voltage state due to a short circuit. Repairs the effect of dark spots. [0003] The machines used to repair the bright spots of the above-mentioned display panels are further described below. Please refer to Figure 1A , Figure 1A is a schematic diagram...
