Problems solved by technology

However, performing both visual and overall testing separately means doubling the time, labor and space required to perform both tests
[0009] In addition, the vision pattern (i.e., shorting bars) must be removed before performing the module process, therefore, it is not possible to perform the vision test in the module process

[0065] Referring to Figures 6 to 9 illustrating an FPD inspection device according to a second embodiment of the present invention, the inspection device includes: a main connection frame 100, a plurality of overall testing units 109; a plurality of vertical moving units 135; a sub-connection frame 126; a plurality of visual test cells 119; and a plurality of resilient members 124. Through the use of the fastening member 102, a plurality of overall test units 109 for performing an overall test on the FPD panel are fixedly installed on the main connection frame 100 such that they are spaced apart from each other by a constant distance. Through the use of fastening parts 102, a plurality of vertical moving units 135 are also fixedly installed on the main connecting frame 100, so that each vertical moving unit 135 is located between two adjacent overall testing units 109 on the main connecting frame 100 between. The vertical moving unit 135 is used to bring the vision test unit ...

Abstract

Disclosed is an inspection method and an apparatus of flat display pane capable of performing continuously a visual test and a collectivity test using the same equipment. The inspection method used for flat panel display (FPD) comprises a loading process used for fixing a flat panel display transferred to an inspecting stand to an inspecting pad; an overall test process used for applying an electric power and a control signal to a channel part of said inspecting pad through a plurality of probes of the overall test unit after the FPD inspection device comprising the overall test unit and the visual test unit is set to the inspecting pad, through which an overall test screen is displayed on the flat panel display to detect defects of the flat panel display through the overall test screen; and a visual test process used for contacting the visual test unit partly with the channel part of the inspecting pad to short circuit said pad in the channel part, through which a visual test screen is displayed on the flat panel display to detect the line defects and the element defects of the flat panel display through the visual test screen.

Description

technical field [0001] The present invention relates to an inspection method and apparatus for a flat panel display (FPD). [0002] More specifically, the present invention relates to an FPD inspection method and apparatus that allow visual testing and overall testing to be performed sequentially with the same equipment. Background technique [0003] In the manufacture of flat panel displays, including liquid crystal displays (LCDs), before being assembled into a finished flat panel display product, they will undergo certain processes for checking the presence of defects in the FPD panel. [0004] In order to inspect the FPD panel before assembly, first, the inspection pad to which the driver IC is attached is brought into contact with the inspection probe. Thereafter, electric power and control signals applied from the driving IC to the inspection probe are applied to the FPD panel via the inspection pad, so as to output an overall test screen on the FPD panel. By using t...
