    Abstract: A display device includes a signal receiver, a signal generator, and a signal corrector. The signal receiver receives an image signal. The signal generator generates a data signal for each of a first color pixel and a second color pixel based on the image signal. The signal corrector generates corrected data for the first color pixel based on the data signal for the second color pixel in a single driving mode. The first color pixel and the second color pixel emit light of different grayscale values of a same color. The first color pixel is driven and the second color pixel is not driven in the single driving mode.

    Abstract: Provided is a method of manufacturing a polymer electret. The method of manufacturing a polymer electrets includes forming a polymer thin film, which includes a block copolymer (BCP) having two or more polymer chains covalently bonded together; forming a nano-structure of the BCP in which a first block formed by first polymer chains that self-assemble together and a second block formed by second polymer chains that self-assemble together are micro-phase-separated, by performing an annealing process on the polymer thin film; forming a porous polymer film with a nano-pore by selectively removing one of the first block and the second block; and charging the porous polymer film.
