Default Re: Sharp EL displays LJ640U80

Yeh, they are essentially a plasma display or electro luminescent (EL).
Also made by planar (USA) and others. Used on industrial video equipment such as digital mixers and VTRs.
Of course the display itself could be faulty, dragging it all down or the driver ICs.
