Display device with photovoltaic converter
First Claim
1. A display device comprisinga first supporting platea second supporting platean electro-optical medium between said plates,a plurality of pixels arranged in an array of rows and columns, each pixel comprising a pair of picture electrodes facing each other on respective supporting plates, said picture electrodes being arranged in rows on said first supporting plate and in columns on said second supporting plate,a row electrode connected to each row of picture electrodes on said first supporting plate,a switching element electrically connected between each picture electrode on said first supporting plate and said row electrode,a column electrode connected to each column of picture electrodes on said second supporting plate,an auxiliary voltage electrode corresponding to each row electrode, anda photovoltaic converter electrically connected between each row electrode and the corresponding auxiliary voltage electrode, said photovoltaic converter having a photovoltaic voltage which is high enough to keep the switching element either conductive or non-conductive.
