  • Patent number: 8885243
    Abstract: An electrowetting display device including a first base substrate, a second base substrate facing the first base substrate, a first electrode disposed on the first base substrate, a second electrode disposed on the second base substrate to face the first electrode, a partition wall disposed between the first and second electrodes to define a receiving area, a hydrophobic layer disposed on the first electrode, a hydrophilic layer disposed on the second electrode, and first and second fluids accommodated in the receiving area and immiscible with each other. At least one of the first fluid and the second fluid has a polarity. The hydrophilic layer allows droplets separated from a hydrophobic fluid of the first and second fluids to be merged with the hydrophobic fluid. Accordingly, a change in amount of the fluids in each pixel is prevented.

  • Patent number: 8542200
    Abstract: An image display device has touch sensing sensor components integrally distributed amongst pixel components of the device. In one embodiment, the distribution is one sensor component per one pixel component. In one embodiment, the pixel component forms a pixel portion of an image by selectively reflecting light and the sensor component is composed of a material that reflects light. More specifically, in one embodiment the light reflecting pixel component is an electrophoretic unit and the sensor component includes a layer of titanium having a color filter layer disposed below it and thus protectively covering it. Reflection of light from the light reflecting sensor layer is reduced by providing an anti-reflection layer above it. The sensor component changes resistance in response to change of local temperature or of an amount of infrared radiation impinging on it. Its resistance is measured by way of two wires connected thereto and extending through contact holes provided in the color filter layer.

  • Patent number: 8514479
    Abstract: An electro-wetting display includes a first substrate, a second substrate which faces the first substrate, and a fluid layer between the first and second substrates. The first substrate includes a plurality of gate lines, a plurality of data lines, and a plurality of pixels connected to the gate lines and the data lines. A fluid layer includes a first fluid layer having a color and a second fluid layer which is transparent. Each pixel includes a switching device, a pixel electrode in connection with the switching device, and a spacing electrode. The switching device is connected to an i-th gate line of the gate lines and a j-th data line of the data lines. The spacing electrode is adjacent to a side of the pixel electrode and in connection with a (i?1)th gate line of the gate lines.
