  • Patent number: 7291860
    Abstract: A gate line extending in a horizontal direction is formed on an insulating substrate, and a data line is formed perpendicular to the gate line defining a pixel of a matrix array. Pixel electrodes receiving image signals through the data line are formed in a pixel, and a thin film transistor having a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode connected to the pixel electrode is formed on the portion where the gate lines and the data lines intersect. A storage wire including a storage electrode line in the horizontal direction, a storage electrode connected to the storage electrode line, and at least one of the storage electrode connection portions connecting storage electrodes of neighboring pixels is formed in the same direction as the gate line.

  • Patent number: 6590624
    Abstract: Test thin film transistors are provided outside of the pixel region of an LCD panel that includes an array of pixel thin film transistors and intersecting arrays of spaced apart data lines and gate lines connected to the array of pixel thin film transistors. A respective test thin film transistor is connected to a respective one of the data lines or gate lines. At least subgroups of the test thin film transistors are commonly connected to provide common energization of subgroups of data lines or test lines for gross testing of the LCD panels. Rubber pads are therefore not required to energize each individual data line or gate line for gross testing. Moreover, after testing is completed, test thin film transistors need not be cut or otherwise mechanically disconnected. Test thin film transistors may be organized for tape automated bonding (TAB) LCD panels or for chip on glass (COG) LCD panels. Associated methods are also provided.
