Abstract (en)
[origin: WO2010100147A1] The invention relates to a device comprising a stack of the following layers, namely: a first substrate with a glazing function (V1), a first electronically conductive layer (TCC1) with an associated current supply, an electroactive layer (EA), a second electronically conductive layer (TCC2) with an associated current supply, and a second substrate with a glazing function (V2). According to the invention, each of the layers, TCC1 and TCC2, is selected to have a resistance per unit area R? that allows same to have an equipotential surface in terms of coloration and discoloration, each of said layers having a variable resistance R? that diminishes gradually from the periphery towards the centre of the electronically controllable device and R? being selected at the centre of the glazing in the zone(s) farthest from the current supplies, such that the ohmic drop across the central surface of the substrates of the glazing in the zone(s) farthest from the current supplies is at most equal to five percent of the value of the voltage applied at the terminals of the device.
