Abstract (en)
[origin: FR2833741A1] The invention concerns a display panel comprising: a front electrode array (18) and a rear electrode array (11); an electroluminescent layer (16) forming, for each cell, an electroluminescent element (E<SB>EL</SB>) connected to an electrode of the front array in A with, in parallel and in accordance with the invention, a shunt element (E<SB>S.EL</SB>); a photoconductive layer (12) forming, for each cell (1), a photoconductive element (E<SB>PC</SB>) connected to an electrode of the rear array (11) in B; means for optical coupling between the electroluminescent element (E<SB>EL</SB>) and the photoconductive element (E<SB>PC</SB>). The shunt of the invention substantially improves memory effect.
[origin: FR2833741A1] The display panel has a front (18) and back (11) network of electrodes, an organic electroluminescent layer (16) forming, for each cell, an electroluminescent element (EEL)connected to an electrode of the front network (A), with a parallel resistance (ERS). A photoconductive layer (12) forms, for each cell, a photoconductor element (EPC) connected to an electrode of the back network (B).
