Abstract
Circuits for displaying an input image in improved perceived resolution are described. A circuit includes memory cells, a horizontal decoder and a vertical decoder. Each of the memory cells is provided to store a pixel value to drive a pixel element on a display. The horizontal decoder (X-decoder) includes horizontal switches, each of the horizontal switches provided to address at least two rows of the cells simultaneously. Each of the horizontal switches is controlled by a horizontal switch signal to toggle among three rows of the cells with the middle row of the cells always selected. The vertical decoder (Y-decoder) includes vertical switches, each of the vertical switches provided to address at least two columns of the cells simultaneously. Each of the vertical switches is controlled by a vertical switch signal to toggle among three columns of the cells with the middle column of the cells always selected.
