Abstract

A method for calibrating the gamma curve of a liquid crystal display, which comprises: (1) providing a measured gamma curve for a liquid crystal display to be calibrated; (2) calculating a plurality of calibration voltage values for the measured gamma curve by a numerical calculation method; (3) storing a plurality of the calibration voltage values by a memory means; (4) generating a clock signal for controlling the scanning operation in the liquid crystal display by a timing means; (5) generating a plurality of calibration voltage signals from the calibration voltage values by a conversion means, while referencing the clock signal; and (6) dynamically calibrating the error of the visual angle of the liquid crystal display by changing the transmission of a plurality of horizontal scanning lines in the liquid crystal display using the plurality of calibration voltage signals.
