ABSTRACT:
This invention provides a method for scanning a thin film transistor liquid crystal display which eliminates the undesirable brightness fluctuations in the display due to parasitic capacitance. When conventional scanning methods are used in thin film transistor liquid crystal displays parasitic capacitance between the gate of the thin film transistors and the pixels causes fluctuations in brightness of the pixels. This method scans only one row of the display at a time and the brightness fluctuations of the pixels are eliminated.
