  • Publication number: 20100149621
    Abstract: A light valve unit may include a first conductive layer and a second conductive layer disposed on opposite sides of each other with respect to a plurality of cells in which at least some of the cells include a first material and a second material. The first material may have a lower light transmissivity property than the second material and a position of the first material within a corresponding cell may be changeable responsive to application of an electric field between the first and second conductive layers. The second conductive layer may include at least two electrodes and a gap defined between the two electrodes. A portion of the light valve unit adjacent to the gap may be configured to have a transmissivity that is substantially less than transmissivity of a portion of the light valve unit adjacent to cells across which the electric field is applied, but greater than or equal to transmissivity of a portion of the light valve unit adjacent to cells across which the electric field is not applied.

  • Publication number: 20090207358
    Abstract: Horizontal-switching flexible liquid crystal displays (LCD) and fabrication methods thereof are provided. The horizontal-switching flexible liquid crystal display includes a flexible first substrate, a second substrate and a liquid crystal (LC) layer interposed therebetween. The LC layer consists of liquid crystal molecules affected by a horizontal field and divided into an upper portion and a lower portion. At least one pair of a patterned pixel electrode and a common electrode is disposed on the first substrate. The pixel electrode and the common electrode are formed on the same plane, thereby generating a horizontal field during operation. First and second alignment layers allow the LC molecules of the LC layer to be in a substantially vertical alignment. The phase retardation of the horizontal-switching LCD is due to the lower portion of the LC layer.

  • Publication number: 20090103159
    Abstract: Electrowetting display devices are presented. The electrowetting display includes a first substrate and an opposing second substrate with a transparent polar fluid layer and an opaque non-polar fluid layer insoluble with each other and interposed between the first and second substrates. A first transparent electrode is disposed on the first substrate. A second transparent electrode is disposed on the second substrate. A dielectric layer is disposed on the second transparent electrode. A reflective plate structure is interposed between the second transparent electrode and the second substrate, thereby defining a reflective region and a transmission region. A backlight plate is disposed on the back of the second substrate. During operation, the opaque non-polar fluid converges, therefore, exposing equal areas of reflective region and transmission region.
