Abstract
Official abstract text for this publication.
Disclosed is a driver circuit structure integrated in a display panel. The driver circuit structure includes a plurality of transistors and a backup transistor. After completing the driver circuit structure, the disclosure inspects it to find an inactive transistor. The inspection process first, isolates the electrical connection between the inactive transistor and the first electrode line and/or the electrical connection between the inactive transistor and the second electrode line. Next, the source electrode of the backup transistor and the first electrode line and/or electrically connecting the drain electrode of the backup transistor and the second electrode line are electrical connected.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for repairing a driver circuit structure, comprising: inspecting the driver circuit structure to find an inactive transistor; electrically isolating the connection between the inactive transistor and the first electrode line and/or the connection between the inactive transistor and the second electrode line; and electrically connecting a backup transistor source electrode and the first electrode line and/or electrically connecting a backup trans…
