(Maybe)The prototype picture of the contrefaited TI-Nspire

[BrainPortable]

Some time ago,I posted some pictures about the contrefaited TI-Nspire made by Chinese.Now,I brought here a more interesting thing:The prototype(Maybe) picture of this thing.
This picture is used for asking for a patent for this product's appearence,and not clear.(Just copied the appearence of TI-Nspire and ask for a patent? ).It's patent is asked by Dayan company in 2011(with this picture),and it's began to be sold in 2012,so this picture may be a prototype.
In this picture,we can see that the prototype's 2ndf,on, "变量"(which means "alpha"),number keys are not the same color as the picture given by the online shop.Besides,the type"DY-8812"is printed in white on this prototype,which is printed in yellow on the MP version.

Nice find.
So, even conterfeited calculators have not for sale prototypes, interesting
