The photovoltaic effect is commercially used for electricity generation and as photosensors.

Electro–optics is a branch of electrical engineering, electronic engineering, materials science, and material physics involving components, electronic devices such as lasers, laser diodes, LEDs, waveguides, etc. which operate by the propagation and interaction of light with various tailored materials. It is closely related to photonics, the branch of optics that involves the application of the generation of photons. It is not only concerned with the "electro–optic effect", since it deals with the interaction between the electromagnetic (optical) and the electrical (electronic) states of materi

The Heliodisplay is an air-based display that uses water condensed from the air already present in the operating environment. The system, developed by IO2 Technology in 2001, uses a projection unit focused onto multiple layers of air and micron-sized atomized particles in midair, resulting in a two-dimensional display with no visible projection surface. This is similar in principle to the cinematic technique of rear projection. As dark areas of the image may appear invisible, the image may be more realistic than on a projection screen, although it is not volumetric. The system may be viewed fr

thumb|180px|The 3LCD Logo 3LCD is the name and brand of a major LCD projection color image generation technology used in modern digital projectors. 3LCD technology was developed and refined by Japanese imaging company Epson in the 1980s and was first licensed for use in projectors in 1988. In January 1989, Epson launched its first 3LCD projector, the VPJ-700.
