Abstract
Techniques for displaying an input image in improved perceived resolution are described. In one aspect, a circuit is designed to include a set of memory cells, a horizontal decoder and a vertical decoder. An input image is received at an interface to the memory, the input is expanded into two separate frames in the memory, where the size of each of the two frames is identical to that of the input image. Image data in at least one of the two frames are modulated in amplitude and/or in phase. The first and second frames are then read out or displayed alternatively at twice the refresh rate originally set for the input image to achieve the perceived resolution.
