Abstract: The present invention discloses a slit nozzle cleaning device for coaters. The slit nozzle cleaning device for coaters comprises a heating source, a crucible and a mixing means, the heating source is used to heat the materials in the crucible; the mixing means is used to mix the materials in the crucible. The mixing means is used to mix the materials in the crucible, thus a uniform heating environment in the crucible can be formed.

Abstract: A scan driving circuit includes a pull-up assembly, a pull-up control assembly that drives the pull-up assembly, a pull-down maintaining assembly, and a reference low-level signal. The reference low-level signal includes a first reference low-level signal and a second reference low-level signal. When the current scanning line is inactive, the pull-down maintaining assembly controls the reference low-level to be sent to the current scanning line and the output end of the pull-up control assembly according to a pull-down maintaining signal.

Abstract: The present invention discloses a packaging apparatus, comprising multiple packaging elements, each packaging element comprises a slot for receiving a LCD module, and the packaging apparatus further comprises a connecting means for integrating the multiple packaging elements side by side. Therefore, the packaging apparatus can be used for both LCD modules and end-products such as TV, display devices, the packaging cost can be reduced.

Abstract: The present invention discloses a repairing line structure for repairing a breakage at a crossing point of electric wires extending along different directions on a thin film transistor panel. The repairing line structure includes a repair line extending from a same side of the electric wire where the breakage is defined and connecting opposite ends of the breakage and an amorphous silicon protection pattern. The repairing line traverses the other electric wire crossing with the electric wire where the breakage is defined. The amorphous silicon protection pattern is located between the repairing line and the electric wire traversed by the repairing line.
