摘要:
A stacked color liquid crystal display uses shared electrode addressing including a plurality of liquid crystal layers each sandwiched between electrically conductive layers. Adjacent liquid crystal layers share one or two electrode layers located between the adjacent liquid crystal layers. A driving scheme is provided that allows the display to be driven by updating the liquid crystal layers sequentially, concurrently, or some combination of the two. Further, a method of manufacturing the display using a deposition process is also disclosed.
摘要:
A modular and configurable display driver for driving a bistable liquid crystal display. The driver has configurable outputs set by a plurality of configuration bits for driving rows or columns of various displays configurations. Thus, the driver can be economically mass produced for use in many products.
摘要:
The present invention is directed to an integrated, reflective bistable, cholesteric liquid crystal display and solar cell assembly providing electrical energy to power display electronics. The liquid crystal display includes the layer of cholesteric liquid crystal material sandwiched between first and second transparent substrates. An inner surface of the first substrate and an inner surface of the second substrate bound the layer of liquid crystal material and the first substrate is closest to a viewer of the display. A first set of conductive electrodes is disposed on the inner surface of the first substrate and a second set of conductive electrodes is disposed on the inner surface of the second substrate. Display driver circuitry is electrically coupled to the first and the second sets of conductive electrodes for generating desired voltage differentials between electrodes of the first set of conductive electrodes and electrodes of the second set of conductive electrodes. A solar cell assembly that is provided includes a solar cell or solar panel positioned behind the second substrate and electrically coupled to a rechargeable energy storage device, such as a rechargeable battery. The solar cell receives illumination passing through the first substrate, liquid crystal material and the second substrate and converts the illumination incident on the solar cell to electrical energy to supply power to the rechargeable energy storage device. The cholesteric liquid crystal material permits transmission of incident light regardless of the configuration of the liquid crystal material.
