摘要:
A method for assembling a device. The method comprises placing a functional element in a first opening formed in a template substrate and transferring the functional element to a device substrate having a second opening formed therein wherein the functional element is held within the second opening and against an adhesive film coupled to the device substrate.

According to an embodiment of the invention, a patch antenna includes a patch coupled to a ground plane. The ground plane includes a first and second strip line. When the first strip line is activated, the antenna generates a signal having a first polarization, and when the second strip line is activated, the antenna generates a second polarization. The first polarization may be a horizontal polarization, and the second polarization may be a vertical polarization. The antenna may be incorporated into a radio frequency identification (RFID) interrogator, which may be used to read RFID tags attached to individual items.
摘要:
An electrophoretic display comprises a fluid and a plurality of nanoparticles having diameters substantially less the wavelengths of visible light such that, when the nanoparticles are in a dispersed state and uniformly dispersed throughout the fluid, the fluid presents a first optical characteristic, but when the nanoparticles are in an aggregated state in which they are gathered into aggregates substantially larger than the individual nanoparticles, the fluid presents a second optical characteristic different from the first optical characteristic. The electrophoretic display further comprises at least one electrode arranged to apply an electric field to the nanoparticle-containing fluid and thereby move the nanoparticles between their dispersed and aggregated states. Various compound particles comprising multiple nanoparticles, alone or in combination with larger objects, and processes for the preparation of such compound particles, are also described.

An electronic device may be provided with a display having a thin-film transistor layer. One or more holes in the thin-film transistor layer may be used to form pathways from display circuitry to other circuitry underneath the display. One or more conductive bridges may pass through holes in the thin-film transistor layer and may have one end that couples to the display circuitry and a second end that couples to a printed circuit underneath the display. These conductive bridges may be formed from wire bonding. Wire bond connections may be encapsulated with potting material to improve the reliability of the wire bond and increase the resiliency of the display. Display signal lines may be routed through holes in a thin-film transistor layer to run along a backside of the display thereby reducing the need for space in the border region for display circuitry.

Novel addressing schemes for controlling electronically addressable displays include a scheme for rear-addressing displays, which allows for in-plane switching of the display material. Other schemes include a rear-addressing scheme which uses a retroreflecting surface to enable greater viewing angle and contrast. Another scheme includes an electrode structure that facilitates manufacture and control of a color display. Another electrode structure facilitates addressing a display using an electrostatic stylus. Methods of using the disclosed electrode structures are also disclosed. Another scheme includes devices combining display materials with silicon transistor addressing structures.

A liquid crystal display is made from an encapsulated liquid crystal structure comprising a liquid crystal composition dispersed in a containment medium. Selected additives may be added to the encapsulated liquid crystal structure to improve performance characteristics such as the operating field, the hysteresis, and the voltage holding ratio.

摘要:
A liquid crystal apparatus (30) comprising a containment medium (56), a birefringent liquid crystal material (38) and a pleochroic dye (54) contained in the liquid crystal material The difference between the ordinary and extraordinary indices of refraction of the liquid crystal material is between about 0.23 and 0.30. The liquid crystal material is dispersed in plural volumes in the containment medium. A pleochroic dye may be present in the liquid crystal material in a concentration of about 0.5% to 3.0%. The apparatus has enhanced backscattering in the field-off state and enhanced light transmission in the field-on state.
