Abstract: A liquid crystal display device include a gamma a voltage controller. The gamma voltage controller includes a voltage-divider network of resistive elements and is part of a gamma voltage circuit, which also includes a programmable digital-to-analog converter. The output voltage signals from the programmable digital-to-analog converter are input to the gamma voltage controller for requisite voltage division. The voltage difference between any two voltage signals output from the gamma voltage controller (i.e., the gamma reference voltage signals) can be finely aligned by setting appropriate values for different resistive elements in the gamma voltage controller. This allows generation of gamma reference voltage signals whose voltages can be precisely controlled according to the T-V characteristics of a liquid crystal display panel in the liquid crystal display device.
