Plan display screen testing device

Abstract

An inspection apparatus for a flat display panel designed to allow panels of different sizes, as an object of inspection, to be aligned on a stage. The inspection apparatus comprises a stage having a panel of a standard size mounted thereon, and first and second aligning means respectively provided at front, rear, right and left sides of the stage to align the panel in horizontal and longitudinal directions. The inspection apparatus further comprises fourth aligning means provided to be lifted and lowered below the stage and to align a small panel having predetermined width and length, one of which is smaller than that of the panel of the standard size, in horizontal and longitudinal directions by concurrently pressing edges of the small panel. The fourth aligning means comprise fourth aligning portions provided to face each other at respective edges of the small panel to press the edges of the small panel, and vertical conveying portions to lift and lower the fourth aligning portions when supplying and discharging the small panel.

Description

technical field [0001] The present invention relates to a flat display screen inspection device, in particular to a flat display screen inspection device, which enables display screens of different sizes as inspection objects to be calibrated on a platform, and the deformation of the platform due to the weight of the display screen Reduced to a minimum, preventing adverse effects on the display. Background technique [0002] In general, flat panel displays are a new generation of display devices developed to replace CRT (cathode ray tubes) used as televisions or computer monitors, for flat panel displays such as LCD (liquid crystal display), PDP (Plasma Display), EL (Electro Luminance Display), etc. are rapidly increasing in demand. [0003] In the process of manufacturing a display screen as described above, before integrating backlights, control circuits, etc. , circuit defects, uniformity of spacing between substrates placed on the display, scratches, etc., so as to sor...

AI Technical Summary

Problems solved by technology

However, in this case, some problems arise again: the inspection device should be increased to support the weight of the stone material; and in order to install various additional devices on the platform, the stone material must be processed, and the processing process Very cumbersome and reduces the service life of the stone platform due to stone cracking during processing
