Abstract: In a light emitting apparatus, all pixels are fabricated using monochrome light-emitting materials. Since the light transmittances of color filters or color conversion layers are not uniform among red (R), green (G), and blue (B), exact white color cannot be displayed. In the present invention, dots for producing these colors of light, i.e., red (R), green (G), and blue (B), are arranged parallel to writing scan lines and to erasing scan lines. The brightnesses are made uniform by controlling the emission times of the emitted colors of light. According to the brightnesses obtained after passage through the colored layer with the lowest light transmittance, the emission times of colors of light passed through the other colored layers are shortened. Thus, as the brightness differences after passage can be reduced, the light emitting apparatus can display exact white color.

Abstract: Subsets of volume data are sequentially stored for volume rendering from two dimensional textures. For example, pairs of adjacent two-dimensional images are loaded into RAM or cache. Strips of texture data are interpolated for polygons extending between the two-dimensional images. The strips or polygons are more orthogonal to a viewing direction than the two-dimensional images. After interpolating texture data from the two-dimensional images for a plurality of non-coplanar polygons, the texture data is rendered. The rendered information represents one portion of the three dimensional representation. Other portions are rendered by repeating the process for other pairs or subset groups of adjacent two-dimensional images. A lower cost apparatus, such as a programmed computer or a GPU with a limited amount of memory, is able to render images for three dimensional representations of very large three-dimensional arrays. The images may be rendered without copying volume data for different main axes.

In this way, a director can more easily select among available S-MEMs to choose those that maintain a particular appearance for a succession of scenes.
