Methods and systems are disclosed to provide intra-pixel illumination to a modulating display panel, where regions of a pixel are provided incident light with controlled intensity and color at different periods of the panel's addressing cycle. This can lead to increased resolution beyond that intrinsic to the panel's physical make up, providing an enhanced resolution 2D panel, as well as a high resolution panel suitable for autostereoscopic purposes when used with a further lens array. For example, when the left hand side of all pixels are illuminated in one frame creating an image, and the right hand side of the pixels are illuminated within a second frame creating a further image, then the combined image, assuming temporal averaging, is twice the native resolution. Despite the temporal trade off, the eye's tolerance to local variation of color and intensity makes this feasible with realistic addressing periods. |
