摘要：A common voltage adjustment apparatus for adjusting a common voltage of aliquid crystal display (LCD) panel includes a data-read-write circuit and an output circuit.The data-read-write circuit includes a one-time-programmable (OTP) memory moduleand a control interface unit. The OTP memory module includes several OTP memories.
The control interface unit outputs common-voltage-setting data according to a controlsignal and selectively stores the common-voltage-setting data into an unwritten OTPmemory in the OTP memory module. The output circuit includes a reference-voltagegenerator and a digital-to-analog converter (DAC). The reference-voltage generatorgenerates a reference voltage. The DAC converts the common-voltage-setting data intoan output voltage according to the reference voltage.
