Reference voltage generating circuit for liquid crystal display |
摘要 |
Disclosed is a reference voltage generating circuit for a liquid crystal display liquid crystal display. The reference voltage generating circuit comprising: an analog voltage generating means for pre-storing a synchronizing signal and digital data signals inputted from outside in response to a write-enable signal, and converting the stored digital data signals into multiple sets of analog voltage signal pairs in response to an output-enable signal; a plurality of variable reference voltage generating means for voltage-distributing corresponding analog voltage signal pairs from among the analog voltage signal pairs generated by the analog voltage generating means, and outputting a plurality of variable reference voltage signals, respectively; a plurality of fixed reference voltage generating means for voltage-distributing a boosted source voltage, so as to output a plurality of fixed reference voltage signals respectively; and a source-driver integrated circuit for receiving the variable reference voltage signals and the fixed reference voltage signals.
