Abstract:
A new kind of Active-Matrix LCD, called Outside-Active-Matrix LCD (OAM-LCD), is formed by depositing the active-matrix (509) on the outside surface of the LCD substrate (506). Each active component is connected with a related dot electrode (507) of the LCD cell through thin conductive lead (511), which is hidden in the substrate (506). The OAM-LCD can use transmission LC or scattering LC. This OAM-LCD not only makes the large screen LCD feasible, but also is easy to manufacture. The OAM-LCD can be used for making large screen hang-on-wall TV, and super large screen mosaic video display both indoor and outdoor applications. OAM-LCD's features include high brightness, high efficiency, good color quality, long life time, low cost and high contrast, especially under high ambient illumination, such as under direct sunlight.
Abstract:
An optical beam phase shifter includes a liquid crystal cell (20) having an optically-transparent common electrode (30) on a first window (22) and a multiplicity of parallel stripes electrodes (32) on the second window (26). A multiplicity of control signals are applied between the individual stripe electrodes (32) and the common electrode (30), thereby creating local variations of the refractive index of the liquid crystal molecules (24), which variations cause differential phase shifts across the cross section of a light beam incident thereon. The control signals are applied to contact pads (36) affixed to an external surface of the liquid crystal cell (20), which contact pads (36) underlie a plurality of the stripe electrodes (32). A multiplicity of conductors (34) extend through a transparent insulating layer (40) to couple the control signals to the stripe electrodes (32). The stripe electrodes (32) are optically-transparent, and the incident beam is reflected from the contact pads (36). In another embodiment, the stripe electrodes are reflective, and the incident beam is reflected therefrom.
Abstract:
A microdisplay module (21) having a reduced size is disclosed. Conventional modules (e.g. of the LCOS type) require a large region of the package substrate (23) to accommodate and fix a flat flexible circuit connector (32) to them. The connector protrudes from the module in the same plane as the LCOS chip and the package substrate, additionally taking up significant space outside the module. In display systems with limited space there may be insufficient clearance, which can result in component failure and complicated assembly and testing. In the disclosed module, the flexible connector (32) is connected to the rear side of the package substrate (23). Electrical connection between the connector (32) and the module pads (28) on the front side are facilitated by via holes (29) passing through the substrate (23). The connector may be bent up around the edge of the package substrate to provide an improved clearance.
Abstract:
A method of manufacturing a coating for an e-paper assembly includes forming a coating layer from conductive particles dispersed within an insulative matrix. A field is applied to cause the conductive particles to align in generally parallel, spaced apart elongate patterns that are generally perpendicular to a plane through which the coating layer extends. At ambient temperatures and without applied pressure, the coating layer is cured via radiation energy while maintaining the applied field.
Abstract:
A charge-receiving layer for an e-paper assembly includes a plurality of conductive paths spaced apart throughout an insulative matrix, with each conductive path including at least one elongate pattern of conductive particles.
Abstract:
A system for providing an electrical interface (10) across a sealed boundary (2,3) may include a frame (1,9A) in sealed engagement with at least a portion of a substrate (12,13). The substrate (12,13) may be in communication with an electrochromic device. The system may further include first and second conduits (75,80). The first conduit (75) may be on a first side of the substrate (12,13) and a second conduit (80) may be on a second side of the substrate. The second conduit (80) may be in communication with the first conduit (75) through at least one of the seal (2,3), a space between the seal (2,3) and the frame (1,9A), and a space between the seal (2,3) and the substrate (12,13).
