Patent ID: 8866722

Claim:
A driving apparatus, applied to a liquid crystal display, the driving apparatus comprising: 2N channels, divided into N channel groups, N being a positive integer, each channel group comprising a first channel and a second channel adjacent to the first channel, the first channel comprising at least one first latch module, a first level shift module, a P-type digital/analog conversion module, a first resistor ladder conversion module, and a P-type amplifying module, and the second channel comprising at least one second latch module, a second level shift module, a N-type digital/analog conversion module, a second resistor ladder conversion module, and a N-type amplifying module; wherein the first level shift module of the first channel is coupled between the at least one first latch module and the P-type digital/analog conversion module, and the second level shift module of the second channel is coupled between the at least one second latch module and the N-type digital/analog conversion module; the P-type digital/analog conversion module of the first channel and the N-type digital/analog conversion module of the second channel are selectively coupled to the first resistor ladder conversion module of the first channel or the second resistor ladder conversion module of the second channel respectively; the P-type amplifying module and the N-type amplifying module are selectively coupled to the first resistor ladder conversion module of the first channel or the second resistor ladder conversion module of the second channel respectively; wherein the at least one first latch module of the first channel receives a first digital signal and the first resistor ladder conversion module outputs a first analog signal corresponding to the first digital signal; the at least one second latch module of the second channel receives a second digital signal and the second resistor ladder conversion module outputs a second analog signal corresponding to the second digital signal.
