  • Patent number: 8958049
    Abstract: The present invention provides a LCD panel and a method for repairing the LCD panel. The LCD panel includes a plurality of data lines and a plurality of subpixel areas. Each subpixel area includes a corresponding pixel electrode and thin film transistor. The subpixel area including a spot defect is electrically connected to a neighboring subpixel area having the same color and in normal operation. The connection between the thin film transistor in the subpixel area including the spot defect and the corresponding data line and the connection between the thin film transistor and the corresponding pixel electrode are cut. Consequently, the subpixel area including the bright spot defect is repaired and able to display normally. The display quality of the LCD panel display is improved. Moreover, the present invention repair method is suitable for the repairing of LCD panels without storage capacitors.

  • Publication number: 20140380477
    Abstract: Disclosed are methods and devices for identifying a tampered webpage and identifying a hijacked web address. The method for identifying a tampered webpage comprises: by simulating a mode of inputting a URL in an address bar of a browser, initiating a request to access a target webpage, and determining obtained page content as the first page content; by simulating a mode of jumping from a link, initiating a request to access the target webpage, and determining obtained page content as the second page content; comparing the first page content with the second page content to obtain a comparison result; and identifying, according to the comparison result, whether the target webpage is a tampered webpage. The present invention can effectively identify whether a target webpage is a tampered webpage, so that an effective means for determining whether a target webpage is tampered is provided to a user and computer services.
