  • Patent number: 6912022
    Abstract: An optical interference color display is provided. The optical interference color display comprises a color filtering substrate, a patterned support layer, a plurality of first electrodes, a plurality of optical films and a plurality of second electrodes. The patterned support layer and the first electrodes are positioned on the color filtering substrate with the patterned support layer between the first electrodes. The optical films are positioned on the first electrodes. The second electrodes is positioned over the first electrodes and supported through the patterned support layer such that an air gap with identical thickness is produce between every pair of second electrode and first electrode. Using the color filtering substrate to show color images, air gap between the first electrodes and the second electrodes are identical and hence simplifies the manufacturing process.

  • Patent number: 6907183
    Abstract: This invention provides a display device and a display method in which a light source irradiates a light transmitting member with light, the light transmitting member outputs a light component having directivity as display light, and the behavior of this light at the interface between a light transmitting material and the light transmitting member is switched between total reflection and transmission by changing the contact state between them, thereby changing the intensity of the display light.

  • Patent number: 6903793
    Abstract: An interconnecting structure and a pixel structure suited to large-sized screens are formed. A counter line/electrode is formed on a TFT substrate, and the counter line/electrode is made of a stacked structure film in which a layer made of aluminum or an alloy essentially containing aluminum is covered with a high-melting point metal film, and a transparent conductive film which covers the stacked structure film.

  • Patent number: 6891591
    Abstract: A method of fabricating slant reflector with bump structure, at least comprising the steps of: providing a substrate; forming a photosensitivity material layer on the substrate; patterning the photosensitivity material layer to form m groups of pattern (m?1, m is positive integral), and each group of pattern includes a plurality of bumps with different bottom area; and jointing the bumps to form a slant surface with bump structure. The photosensitivity material layer is either orderly or randomly patterned to form m groups of patterns. The step of patterning the photosensitivity material layer includes exposing and developing. The invention utilizes one photo-mask with particular pattern to fabricate the bump structure in a simple way.
