UNLABELLED Graphene quantum dots (GQDs), a newly emerging 0-dimensional graphene based material, have been widely exploited in optoelectronic devices due to their tunable optical and electronic properties depending on their functional groups. Moreover, the dispersibility of GQDs in common solvents depending on hydrophobicity or hydrophilicity can be(More)
This paper proposes an error diffusion method for improvement of gray scale rendition in plasma display panel(PDP). The conventional error diffusion method in PDP, which includes data separation for display and error part, may have a danger of wrong calculation of error to diffuse. The proposed approach suppressed the halftone artifact by calculating the(More)
