  • Publication number: 20110147747
    Abstract: A display device includes a flexible panel and a cover member. The flexible panel includes a first substrate and a second substrate. The first substrate includes a first support layer in which an organic insulation layer and an inorganic insulation layer are stacked thereon, and a thin-film transistor and a pixel electrode disposed on the first support layer. The second substrate is opposite to the first substrate. The second substrate includes an organic insulation layer and a second support layer on which the inorganic insulation layer is deposited. The cover member covers an outer surface of the flexible panel. Thus, a display device is manufactured by using a support layer on which an organic insulation layer and an inorganic insulation layer are coated as a base substrate, so that defects generated in a manufacturing process may be prevented.

  • Publication number: 20110050642
    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.

  • Publication number: 20080302482
    Abstract: A substrate processing apparatus includes a substrate processing part which processes a substrate and a particle remover which generates an electric field. The particle remover generates the electric field adjacent to a sidewall of a chamber of the substrate processing apparatus, and the electric field guides particles formed during which the substrate is processed, to prevent the particles from being attached onto the sidewall of the chamber. Thus, the substrate processing apparatus prevents defects of the substrate due to the particles, thereby improving product yield and productivity and reducing a manufacturing cost thereof.
