Abstract: A scan driver includes a plurality of stages. An nth (n is a natural number) stage among the stages includes: a first and a second input circuit for controlling a voltage of a first node in response to a carry signal of a previous stage and a next stage, respectively; a first output circuit for outputting an nth carry signal corresponding to a carry clock signal in response to the voltage of the first node; a second output circuit for outputting an nth scan and an nth sensing signal corresponding to a scan and a sensing clock signal, respectively, in response to the voltage of the first node; and a sampling circuit for storing the carry signal of the previous stage in response to a first select signal, and for supplying a control voltage to the first node in response to a second select signal and the stored carry signal.

Abstract: An organic light emitting diode display device includes a substrate having an emitting area and a non-emitting area. An insulating layer is on the substrate, and the insulating layer includes a plurality of convex portions, a plurality of connecting portions and at least one wall in the emitting area. A height of the at least one wall is greater than a height of the plurality of convex portions. A first electrode is on the substream, emitting layer is on the first electrode, a second electrode is on the emitting layer. The first electrode, the emitting layer and the second electrode constitute a light emitting diode.

Abstract: A self-cleaning device comprises at least one first electrode disposed on a solid material layer, a first dielectric layer disposed on the first electrode, a hydrophobic layer disposed on the first dielectric layer, and at least one mechanical oscillation unit. Electrical oscillation for oscillating a droplet in a horizontal direction is generated by applying a first electric signal to the first electrode, thereby merging droplets formed on the hydrophobic layer, the mechanical oscillation unit moves the merged droplets in a specific direction or atomizes the merged droplets to remove the merged droplets by generating mechanical oscillation for oscillating the droplet in a vertical direction, and each of the droplets has a volume smaller than 3 ?l, and new droplet having a volume more than 3 ?l is generated by the merging.

Abstract: The present disclosure relates to a monomer composition for synthesizing recycled plastic which is extremely reduced in the content of organic impurities such as formic acid and acetic acid while recovering from a (co)polymer synthesized from monomers containing terephthalic acid, a method for preparing the same, and a recycled plastic, molded product, and plasticizer composition using the same.
