  • Patent number: 8159627
    Abstract: Disclosed is a pixel layout structure capable of increasing the capability of detecting amorphous silicon (a-Si) residue defects and a method for manufacturing the same. Wherein, an a-Si dummy layer is disposed on either one side or both sides of each data line. The design of such an a-Si dummy layer is utilized, so that in an existing testing conditions (by making use of an existing automatic array tester in carrying out the test), in case that there exists an a-Si residue in a pixel, the pixel having defects can be detected through an enhanced capacitance coupling effect and an electron conduction effect. Therefore, through the application of the above-mentioned design, the capability of an automatic array tester can effectively be increased in detecting a defective pixel having a-Si residues.

  • Publication number: 20110057905
    Abstract: The present invention provides a touch panel, including a substrate, a plurality of first sensing lines, a plurality of second sensing lines and an insulation layer. The first sensing lines are disposed on the substrate. Each first sensing line extends along a first direction and at least one end of each first sensing line includes a first inspecting region. The second sensing lines are disposed on the substrate. At least one end of each second sensing line includes a second inspecting region and each second sensing line extends along a second direction. The first direction is not parallel to the second direction. The insulation layer covers the first sensing lines and the second sensing lines and exposes the first inspecting regions and the second inspecting regions. The present invention further provides an inspection method of a touch panel.
