Calcium reacting photoproteins are a class of self-illuminating proteins that emit light upon contact with calcium. Fluorescent Proteins are small proteins that change the color of light when excited. Fluorescent Proteins and Calcium Activated Photoproteins can be used to enhance, dazzle, amaze, startle, and otherwise entertain an audience by their direct application on to the audience, surroundings, the actors, or sprayed on settings as in the newer 4D movies. The disclosure comprises novel Coelenterazine compounds and methods of use, including a simple delivery device for the photoprotein to create unique and novel cinematic, theatrical, stage, movie and musical concert optical effects by their luminous reaction upon contact with surfaces that contain calcium. Calcium is ubiquitous in and on most surfaces and in the environment; it is this unique property of calcium that makes this a novel use of the photoproteins for entertainment.

A negative optical power electrowetting optical device is provided. The negative optical power electrowetting optical device includes: a non-conductive liquid having a refractive index; a conductive liquid having a second refractive index; and a dielectric surface in contact with both the conductive and non-conductive liquids. The refractive index of the non-conductive liquid is less than the second refractive index of the conductive liquid and wherein the conductive liquid is immiscible with the non-conductive liquid.

The present invention provides a composition containing an inorganic nano-particle structure absorbing blue light and then emitting light and a siloxane compound; a light-conversion thin-film made of the composition; and a display panel using the film. When using the composition, the light-conversion thin-film as an optical member may have high stability. Further, when using the film, a display panel with excellent stability even under high-temperature and high-water conditions may be realized.
