  • Patent number: 8013946
    Abstract: An LCD is fabricated using a diffraction mask with transmissive, semi-transmissive, and opaque regions. The semi-transmissive region permits formation of a transmission, reflection, or pixel electrode, depending on the type of LCD being fabricated, using the same masking process as that to produce contact holes in an insulating film and a conductive layer. Photoresist exposed through the semi-transmissive region is partially removed during developing that completely removes photoresist in the transmissive or opaque region. The contact holes are formed in the region in which the photoresist is completely removed, the photoresist and underlying conductive layer in the semi-transmissive region are then removed, and the remaining photoresist is stripped.

  • Patent number: 7666695
    Abstract: Provided is an array substrate of an LCD that includes a substrate, an active layer, a first insulating layer, and a gate electrode sequentially formed on the substrate. A source region and a drain region reside in predetermined regions of the active layer and each is doped with impurity ions. A second insulating layer overlies an entire surface of the substrate including the gate electrode. A pixel electrode resides on the second insulating layer. First and second contact holes reside in the first and second insulating layer and expose portions of the source region and the drain region, respectively. A portion of a source electrode contacts the source region through the first contact hole and a first portion of a drain electrode contacts the drain region and a second portion contacts the pixel electrode.

  • Patent number: 7649585
    Abstract: An LCD substrate including multiple LCD panels may be cut along a scribing boundary. All or part of one or more test pads or test signal lines may extend in whole or in part across the scribing boundary. When the LCD substrate is cut along the scribing boundary, the test pads or test signal lines are cut or removed.

  • Publication number: 20040261828
    Abstract: The present invention relates to a foldable tent frame in which a connection frame connected to a column is minimized, and a fabrication is simple and easy, and a fabrication cost is largely decreased, and an economical fabrication is achieved, and a cut-away groove is formed in an engaging part of one side of the top connection part. A rotation protrusion of a rotation part is engaged to the cut-away groove for thereby achieving an easier installation of the rotation part. The rotation protrusion of the rotation part is rotated along the surface of the cut-away groove based on a stable and free rotation, so that it is possible to achieve an easier folding operation of the tent.
