Abstract: A display device of the present disclosure comprises pixels arranged in a display, a data accumulator for accumulating first image data for an N-th frame output through the display, a data receiver for receiving second image data for an (N+1)th frame to be output through the display, and an afterimage controller for correcting a current value corresponding to a grayscale value of the second image data through a convolution operation between a filter, which is set based on the first image data, and the second image data.

Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).
