Driving method for gate-delay compensation of TFT/LCD

Gate delay is one of the biggest limiting factors for large-screen-size, high-resolution thin-film transistor liquid crystal display (TFT/LCD) design. To solve this problem, we have developed a new driving method which can achieve high image quality and reliability and reduce the power consumption with conventional processes, even if gate-line resistance and load capacitance are increased. The new method uses gate-pulse waveforms that separate the functions of feedthrough compensation, with pulse edge timing that greatly reduces errors due to gate delay.
