    摘要： Low voltage piezo-electrophoretic films and displays including low profile piezo-electrophoretic films. Piezo-electrophoretic displays having a layer of electrophoretic material, a first conductive layer, and a piezoelectric material positioned between the layer of electrophoretic material and the first conductive layer, where the piezoelectric material overlaps with a portion of the layer of electrophoretic material, and a portion of the first conductive layer overlaps with the rest of the electrophoretic material. Such films and displays exhibit a high contrast ratio and are useful as security markers, authentication films, or sensors. The films and displays are generally flexible. Some are less than 100 μm in thickness. Some are less than 50 μm in thickness. Piezo-electrophoretic films and displays formed according to the technology described herein do not require an external power source to change optical state.

    摘要： A variable light transmittance sheet comprises a first transparent electrode and a second transparent electrode spaced apart from the first electrode, and between the electrodes an electrophoretic cell containing an electrophoretic ink and one or more non-planar solid polymer elements. In an embodiment, the electrophoretic ink includes charged particles in a suspending fluid, and 75% or more by mass of the suspending fluid is an organosilicone or an aliphatic hydrocarbon and the solid polymer is a fluorinated elastomeric polymer.

    摘要： A hybrid display is disclosed. The hybrid display includes an electrophoretic module configured to display information through reflection of light incident from an exterior thereof, and a light emitting module formed at a lower surface of the electrophoretic module, to output color light to the electrophoretic module. The electrophoretic module includes a first substrate, a second substrate spaced apart from the first substrate, a plurality of capsules disposed between the first substrate and the second substrate, each of the capsules containing particles having a color and a fluid having a color therein, and an electrode configured to apply an electric filed to the capsule, thereby moving the particles. The color light output from the light emitting module is mixed with the color of the fluid, and is then outwardly output. The hybrid display exhibits excellent visibility even in a dark environment, and the background color thereof is variously changeable.

    摘要： A conductive structure is applied to an e-paper device, which includes a driving substrate and an e-paper film. The e-paper film is disposed on the driving substrate, and includes a transparent substrate, a common electrode layer, and a display medium layer disposed between the common electrode layer and the driving substrate. The common electrode layer is disposed on one side of the transparent substrate facing the driving substrate. The display medium layer includes a through hole. The conductive structure is disposed in the through hole and includes a conductive member and at least one spacer. The conductive member is electrically connected to the driving substrate and the common electrode layer. The spacer is disposed in/on the conductive member, and contacts with the driving substrate and the common electrode layer. An e-paper device with the conductive structure is also disclosed.
