An electro-optic display comprises a layer () of a solid electro-optic material, at least one electrode disposed adjacent the layer () of electro-optic material, and a layer () of a lamination adhesive interposed between the layer () of electro-optic material and the electrode, the lamination adhesive () having a higher electrical conductivity in a direction perpendicular to the layer of lamination adhesive than in the plane of the layer.

Electro-optic display and materials for use therein

The invention relates to electro-optic displays and methods for driving such displays. The invention provides (i) electrochromic displays with solid charge transport layers; (ii) apparatus and methods for improving the contrast and reducing the cost of electrochromic displays; (iii) apparatus and methods for sealing electrochromic displays from the outside environment and preventing ingress of contaminants into such a display; and (iv) methods for adjusting the driving of electro-optic displays to allow for environmental and operating parameters.

Electro-optic displays, and methods for driving same

A backplane for an electro-optic display comprises a plurality of pixel electrodes, and an adhesive layer disposed adjacent the backplane, the adhesive layer comprising a plurality of pixel regions disposed adjacent the pixel electrodes of the backplane, and at least one inter-pixel region disposed between two pixels of the backplane, the at least one inter-pixel region having at least one of a lower dielectric constant and a higher volume resistivity than the pixel regions of the adhesive layer.

Backplanes for electro-optic displays

A method for sensing the state of an electrophoretic display includes the steps of applying an electrical signal to a display element, measuring an electrical response for the display element, and deducing the state of the display element from the measured electrical response. Also, the parameters of the display materials are determined using the encapsulated electrophoretic display media as a sensor, either alone or in conjunction with other sensors.

Method and apparatus for determining properties of an electrophoretic display

An electro-optic display comprises first and second substrates and a lamination adhesive layer and a layer of a solid electro-optic material disposed between the first and second substrates, the lamination adhesive layer having a volume resistivity, measured at 10&deg; C., which does not change by a factor of more than about 3 after being held at 25&deg; C. and 45 percent relative humidity for 1000 hours. The electro-optic material is preferably an encapsulated electrophoretic material. Other desirable characteristics of lamination adhesives for use in electro-optic displays are also described.
