In one embodiment of the present invention, a display device is disclosed wherein if a frame luminance is less than a maximum value, the device creates a difference between luminance outputs in the two subframes and sets the luminance difference to a value less than a sub-maximum luminance which is a maximum luminance output in one subframe. With the arrangement, no complete switching of the subframes in which luminance outputs are made occurs at a grayscale level where low luminance replaces high luminance or vice versa. Thus, the grayscale level-luminance curve continues smoothly.

The gene encoding a 4-hydroxybutyryl-Co A transferase has been isolated from bacteria and integrated into the genome of bacteria also expressing a polyhydroxyalkanoate synthase, to yield an improved production process for 4HB-containing polyhydroxyalkanoates using transgenic organisms, including both bacteria and plants. The new pathways provide means for producing 4HB containing PHAs from cheap carbon sources such as sugars and fatty acids, in high yields, which are stable. Useful strains are obtaining by screening strains having integrated into their genomes a gene encoding a 4HB-CoA transferase and/or PHA synthase, for polymer production. Processes for polymer production use recombinant systems that can utilize cheap substrates. Systems are provided which can utilize amino acid degradation pathways, α-ketoglutarate, or succinate as substrate.
