Abstract: A testing apparatus for a display device according to an embodiment of the present invention includes: a substrate; a driving chip mounted on the substrate; and a pad disposed on the substrate and electrically connected to the driving chip, wherein the pad includes a bottom layer electrically connected to the driving chip, and a sheet layer disposed on the bottom layer and electrically connected to the bottom layer, and wherein a lateral surface of the bottom layer is not covered by the sheet layer.

Abstract: Disclosed herein are heat treatment apparatuses and methods for liquid crystal display (LCD) cells, which are capable of rapidly transferring heat to liquid crystals injected into an LCD cell, not only to reduce the time taken for the liquid crystals to be changed into a liquid phase, but also to physically promote diffusion of the liquid crystals, thereby achieving a more uniform distribution of the liquid crystals. The apparatus includes a liquid bath, in which a liquid is contained as a medium to transfer heat to the liquid crystals in the LCD cells, a loading device to load or unload the LCD cells into/from the liquid bath, a heater installed in the liquid bath, the heater heating the liquid contained in the liquid bath and transfer heat to the liquid crystals, and a sound wave transmitter installed in the liquid bath and transmitting sound waves to the liquid crystals.

Abstract: A pallet capable of fixing display panels having various sizes substantially normal to the pallet, a method of fixing the display panels using the pallet, and a method of transferring the pallet are provided. The pallet includes a first supporting unit and a second supporting unit for fixing a display panel, first panel fixing units included in both the first supporting unit and the second supporting unit, the first panel fixing units support a lower end of the display panel, and one or more second panel fixing units included in the first supporting unit and/or the second supporting unit. The one or more second panel fixing units are made of a plurality of disks for fixing at least one of opposing sides of the display panel.
