Abstract: Provided are a packaging device and a display panel packaging method. The device includes: a guide line, a container for containing a package adhesive, a rotary worktable for placing a to-be-packaged device and a winding device for driving the guide line to move. The guide line is mounted on the winding device, and part of the guide line is immerged into the package adhesive so the guide line adhered by the package adhesive passes through the rotary worktable when moving. The to-be-packaged display device is disposed on rotary worktable, thus the guide line contacts with the frit. When the rotary worktable rotates, the guide line moves and passes through the container containing package adhesive. When part of the guide line adhered by package adhesive passes through the rotary worktable, the package adhesive is coated on the frit, thereby achieving uniform coating of the package adhesive under surface tension of frit.

Abstract: The present disclosure relates to an array substrate, a method for fabricating the same, a display panel, and a display device. The array substrate includes an active layer on a substrate, the active layer including a channel region, source/drain regions and a lightly doped drain region, a gate electrode and a first electrode on the active layer, and a gate electrode and the first electrode a first insulating layer, a barrier and a second electrode on the first insulating layer. A projection of the second electrode on the substrate at least partially overlaps that of the first electrode. A projection of the barrier on the substrate covers that of the lightly doped drain region on the substrate. The projection of the barrier on the substrate does not overlap that of the source/drain regions. The barrier and the second electrode are in the same layer.
