Abstract: An exemplary gamma regulating system (20) for an LCD has a test-needed LCD (26), a light sensor (21), and a MCU (24). The LCD displays each gray scale image according to internal presetting standard gamma curve. The light sensor measures a luminance value of the gray scale image displayed by the test-needed LCD, and converts the luminance value to a voltage signal. The MCU compares the voltage signals representing the measured luminance values with the parameter data corresponding to the standard gamma curve, and regulates a gray voltage according the comparing result.
