  • Patent number: 10901285
    Abstract: A first display comprises a layer of electro-optic material with first and second electrodes on opposed sides thereof, at least one electrode. One or both electrodes having at least two spaced contacts, and voltage control means are arranged to vary the potential difference between the two spaced contacts attached to the same electrode. A second display comprises a layer of electro-optic material with a sequence of at least three electrodes adjacent thereto. Voltage control means vary the potential difference between the first and last electrodes of the sequence. The electrodes of the sequence alternate between the two surfaces of the layer of electro-optic material, and have edges which overlap with or lie adjacent the preceding and following electrodes of the sequence. The electrodes, other than the first and last, are electrically isolated such that the potential thereof is controlled by passage of current through the layer of electro-optic material. Methods for driving these displays are also provided.

  • Patent number: 10852615
    Abstract: A laminate which can serve as either a smart window or a smart mirror is formed using first and second substrates coated with transparent first and second electrodes which are separated by foraminous layer and a third grid-like linear electrode insulated from the first and second electrodes. The foraminous layer includes spacers defining a cell space which is filled with a colloidal ink having first and second particles. The first particles have a positive charge and a first color and second particles having a negative charge and a second color different from the first color. By altering the voltages of the first, second and third electrodes, one can achieve different light transmission characteristics which, for example, can alter the color temperature of the light transmitted through the laminate or enhance reflective colors.
