In a display apparatus such as a thin film transistor liquid crystal display (TFT-LCD) or an active matrix organic light emitting diode (AMOLED) display, a plurality of rows of scan lines and a plurality of rows of data lines intersect each other to form a matrix, with the scan lines being sequentially supplied by a gate driver with a scan signal and the data line being synchronously supplied by a data driver with respective data voltages.
Typically, the gate driver is implemented with a plurality of cascaded shift register units. An increase in the size of the display panel and the pixel resolution requires more shift register units in the gate driver to supply scan signals to more scan lines, making it challenging to design a gate drive circuit with a more compact structure (potentially smaller footprint) and smaller power consumption.
