Patent ID: 7687806

Claim:
A method for repairing a thin film transistor array substrate of an E-ink display, the thin film transistor array substrate having a plurality of pixel units, each of the pixel units connected with a scan line and a data line, wherein at least one of the pixel units is defective, the method comprising: providing the thin film transistor array substrate, each of the pixel units including a thin film transistor and a pixel electrode, the thin film transistor having a gate electrode, a source electrode and a drain electrode, wherein the gate electrode, the source electrode and the drain electrode are connected electrically to the scan line, the data line and the pixel electrode respectively, wherein a portion of the pixel electrode is located above the scan line and the scan line further comprises a protruding portion; and forming a repairing portion at the space between the protruding portion of the scan line and the pixel electrode, wherein the repairing portion is utilized to electrically connect the pixel electrode and the scan line so as to maintain a repaired pixel unit of the pixel units to display a color corresponding to a low voltage level for the E-ink display, and the pixel electrode covers the entire protruding portion.
