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: Geo View is a three-dimensional virtual universe in which a real-world or virtual object may be represented by one or more virtual objects whose attributes are derived from attributes of the real-world object via a flexible user-specifiable mapping. Typically a two-dimensional plane located in three-dimensional space is used to visualize the universe of interest.

In addition to the visualisation of various objects, the human observer can attach sounds to objects. The representation of real-world objects with rapidly time-changing attributes may be simplified by the use of Synthetic Strobes, flexible user-specified filters which shift changes in the visual attributes of a shape from one time-domain to another.
