Abstract
An inspection jig for a display panel, used in an inspection system for the display panel and in a method for inspecting the display panel, includes a plate, a ground plate and at least one side holder. The ground plate is disposed on the plate and receives the display panel. The at least one side holder is disposed at a side surface of the plate to control the angle of the plate.
Claims24
An inspection jig for a display panel, the inspection jig comprising:
- a plate;
- a fixing element protruded in a first direction from the plate;
- a ground plate which is disposed on the plate and receives the display panel, the ground plate comprising:
- a bottom plate between the plate and the received display panel, and
- a ground portion comprising side portions each protruded in the first direction from the bottom plate, wherein adjacent side portions are between an inner surface of a same fixing element and outer surfaces of adjacent side surfaces of the received display panel;
- and
- a side holder disposed at a side surface of the plate, wherein the side holder controls an angle of the plate.
