  • Liquid crystal display having compensation circuit for reducing gate delay
    Patent number: 7999776
    Abstract: An exemplary liquid crystal display (400) includes a liquid crystal panel (430), a gate driving circuit (410), a data driving circuit (420), and a compensation circuit (440). The liquid crystal panel includes a plurality of gate lines (401) and a plurality of data lines (402) intersecting with the gate lines. The gate driving circuit is configured for providing a plurality of scanning signals to the gate lines in sequence. The data driving circuit is configured for providing a plurality of gray scale voltages to the data lines. The compensation circuit is configured for compensating the scanning signals. The compensation circuit is charged by alternate of the scanning signals, and discharges each such charge to provide a compensation signal to a gate line corresponding to a next scanning signal.
