|An example of how a Wysip crystal display|
would operate on an iPhone. 1 hour of Sun exposure
could provide 30 minutes of wireless air time, while
adding only about $1 of cost to the overall design.
Wysips Crystal -- which stands for What You See Is Photovoltaic Surface -- has been developed by Sunpartner, which is based in Aix-en-Provence in the south of France. Sunpartner says: "The goal of this partnership is to develop smartphone prototypes powered by solar and artificial light. This project will enable TCL Communication to evaluate the technology in both technical and marketing terms."
TCL also has a French connection, in that it supplies Alcatel with its OneTouch mobile phone. It markets phones in more than 120 countries.

technology which shows different images depending on the
observers position and is used often to create 3D effects
Sunpartner is also working with another two large phone companies. It says it "plans to finalize two agreements in the coming months and sign the first licenses during the first half of 2014."
Last month, Sunpartner completed a second round of funding, bringing its total to €9 million ($12 million) over the past three years, and it plans to raise another €6 million ($8 million) to put Wysips Crystal into production in Rousset.

Sunpartner says Wysips Crystal could also be used in tablets and e-book readers, watches, electronic tags etc, and in intelligent buildings (windows, facades etc).
Sunpartner showed its first prototypes at the Mobile World Congress in Barcelona in February 2013.
