Claim:
1. A see-through dimming panel, comprising: a first transparent substrate layer; a second transparent substrate layer; a suspended-particle-device (SPD) layer between the first and second transparent substrate layers; a first transparent conductor layer between the first transparent substrate layer and the SPD layer; a second transparent conductor layer between the second transparent substrate layer and the SPD layer; a first electrode electrically coupled to the first transparent conductor layer; a second electrode electrically coupled to a first end of the second transparent conductor layer; and a third electrode electrically coupled to a second end of the second transparent conductor layer opposite the first end; wherein an electric potential difference applied between the first and second electrodes controls a transmittance level of the SPD layer; and wherein an electric potential difference applied between the second and third electrodes controls a speed at which the transmittance level of the SPD layer decreases when the electric potential difference applied between the first and second electrodes is decreased.
