Abstract: Polyester polymer compositions are described containing a blend of different polyester polymers. The different polyester polymers are combined with one or more laser additives for producing polymer articles that have excellent laser weldable characteristics. The polymer composition can also contain reinforcing fibers and a lubricant. In one aspect, the laser additive is a carbonaceous material alone or in combination with a quinoline.

Abstract: The present application discloses a gate drive circuit and a display device. The gate drive circuit includes a plurality of cascaded gate drive units, in which one of the gate drive units includes a first layout, an input module and a pull-up module. By receiving a potential changeable signal by the gate of a first transistor or the gate of a second thin-film transistor, it can alleviate or avoid current leakage caused when a first node keeps at a same voltage level for a long time, thereby improving the stability of the potential of the first node.

Abstract: The present application discloses a gate driving circuit and a display panel. The gate driving circuit comprises a plurality of cascaded gate driving modules. A first driving signal can be output through a first output node, and at the same time, a second driving signal with a same phase as the first driving signal can be output through a second output node, and a gate driving sub-module and an in-phase output sub-module share the first output node and a pull-down node, which simplifies a circuit topology of the gate driving circuit.

Abstract: A quick-connection outdoor waterproof electrical connector is provided, having the following features: All of the male terminals and the female terminals are all positioned in a peripheral direction with the same diameter; the female terminal is provided at its connection portion with a “U-shaped” structure; for the internal wall of the cylindrical hole and the external edge of the cylindrical plug, one is provided with an “L-shaped” guide slot and the other with a convex guide pole, with the cylindrical hole being provided at its bottom with an end-plane waterproof washer.
