ABSTRACT:
An apparatus for switching output voltage signals includes a resistor string, a first switching device set for delivering a number of gamma voltage input signals, a second switching device set for delivering a high voltage input signal and a low voltage input signal, and a switch selecting device coupled to the first switching device set and the second switching device set. When the switch selecting device outputs a first signal, the first switching device set can deliver the gamma voltage input signals to the resistor string; when the switch selecting device outputs a second signal, the second switching device set will deliver the high voltage input signal and the low voltage input signal to the resistor string.
