Abstract: A system for inspecting a display panel includes the display panel, a driving circuit unit and a controller. The display panel includes a plurality of pixels positioned in a display area, and first and second test pads positioned in a non-display area. The driving circuit unit is positioned in the non-display area of the display panel, and includes first and second test bumps respectively bonded to the first and second test pads. The controller calculates a bonding resistance between the first and second test pads and the first and second test bumps.
