Problems solved by technology

[0012] However, in the above-mentioned conventional inspector, since the next panel is not fed to the stage during the inspection of the panel, a new panel can be fed to the stage only after the inspected panel is removed to the outside
[0013] Accordingly, it takes a long time from the end of the current panel inspection to the start of the next panel inspection, reducing the efficiency and productivity of the inspection process

Abstract

The present invention provides a flat panel display tester comprising a testing unit including a stage for mounting panels thereon, a panel-conveying unit for separating a tested panel from the stage and simultaneously for feeding an untested panel onto the stage, and a panel-feed unit for discharging the tested panel conveyed by the panel-conveying unit to the outside and for transferring the untested panel to the panel-conveying unit, wherein the panel-conveying unit includes a pair of rails horizontally arranged between the stage and the panel-feed unit; first and second carriers respectively installed on the rails and reciprocating so that panels conveyed along the first and second carriers cross each other; and loaders, respectively provided on the first and second carriers, moving to the stage and the panel-feed unit for directly loading and unloading the panels and then returning to a stand-by state. The flat panel display tester remarkably improves efficiency and productivity of a testing process compared to a conventional flat panel display tester.

Description

technical field [0001] The present invention relates to a flat panel display which inspects a panel mounted on a platform, and more particularly, the present invention relates to an inspector for a flat panel display comprising two carriers for loading and unloading a panel such that the Removal of inspected panels and feeding of uninspected panels can be performed simultaneously. Background technique [0002] As is well known to those skilled in the art, the flat panel display (FPD) is a new type of display that has been developed to replace the cathode ray tube (CRT) used in the monitor of a television or computer. The FPD has many advantages such as light weight, thin profile, high screen quality, and low power consumption rate, and thus is widely used in industry. [0003] Recently, various displays such as liquid crystal displays (LCDs) or plasma display panels (PDPs) have been produced. The manufacturing process for these displays includes steps to inspect the panels...
