Pixel structure having two TFTs connected to pixel electrode, second TFT having floating main gate electrode and top gate electrode, with repair method connecting the gate electrodes of the two TFTs |
摘要 |
A pixel structure includes a backup thin film transistor with a float gate electrode or a float drain electrode and a working thin film transistor. When the pixel of the working thin film transistor does not work, the backup thin film transistor replaces the working thin film transistor to drive the pixel. The method of repairing the pixel is to cut off the connection between the drain electrode of the working thin film transistor and the pixel electrode, and then to connect the main gate electrode or the drain electrode of the backup thin film transistor to the gate electrode or the drain electrode of the working thin film transistor, such that the backup thin film transistor can replace the working thin film transistor to drive the pixel electrode.
