  • Publication number: 20150138474
    Abstract: The present invention provides an ultra-narrow frame liquid crystal display and a COF packaging structure for driving circuits in the ultra-narrow frame liquid crystal display. The COF packaging structure comprises: a sheet of flexible circuit board, with one side thereof bonded with a frame area of a glass substrate of the liquid crystal display, serving as a carrier sheet for chip-on-film flexible packaging; and a plurality of driving chips, bonded with the sheet of flexible circuit board sequentially along a scan direction, wherein a signal circuit between adjacent driving chips is arranged on the sheet of flexible circuit board. The present invention proposes a novel COF packaging structure, wherein the signal circuits required between the driving ICs are relocated to the COF flexible circuit board from the glass substrate by using the sheet of flexible circuit board.

  • Patent number: 7989243
    Abstract: A pixel structure fabricating method is provided. A gate is formed on a substrate. A gate insulation layer covering the gate is formed on the substrate. A channel layer, a source, and a drain are simultaneously formed on the gate insulation layer above the gate. The gate, channel layer, source, and drain form a thin film transistor (TFT). A passivation layer is formed on the TFT and the gate insulation layer. A black matrix is formed on the passivation layer. The black matrix has a contact opening above the drain and a color filter containing opening. A color filer layer is formed within the color filter containing opening through inkjet printing. A dielectric layer is formed on the black matrix and the color filter layer. The dielectric layer and the passivation layer are patterned to expose the drain. A pixel electrode electrically connected to the drain is formed.

  • Patent number: 7598102
    Abstract: A fabricating method for a pixel structure including following procedures is provided. First, a gate and a gate insulator layer are formed sequentially on a substrate. Next, a semiconductor layer, a conductive layer and a photosensitive black matrix having a color filter containing opening are sequentially formed on the gate insulator layer. The photosensitive black matrix includes a first portion and a second portion. A thickness of the first portion is smaller than that of the second portion. A channel, a source and a drain are formed simultaneously using the photosensitive black matrix as a mask. A passivation is formed on the substrate, and a color filer layer is formed within the color filter containing opening via an inkjet printing process and a dielectric layer is formed thereon. Next, a patterning process is applied to expose the drain. Ultimately, a pixel electrode connected to the drain is formed.
