SOURCE DRIVER FOR REDUCING A LAYOUT AREA, CAPABLE OF REDUCING A LAYOUT AREA

摘要

PURPOSE: A source driver for reducing a layout area is provided to reduce layout area by minimizing the number of a circuit device required for a source driver.;CONSTITUTION: A source driver operates a display panel. The source driver comprises a plurality of line pair drive blocks. The line pair drive block drives data line pair. The data line pair is comprised of the first and the second data line. A line pair drive block comprises a data sink, a DEMUXING part(BDMUX), a decoding part(BDEC), and a MUXING part(BMUX). A data sink receives a first and second digital data of the data bus. The demuxing part demuxes digital data. The demuxing part is latched in response to the demuxing latch signal. The demuxing part decodes the data and to generate analog data. The muxing part generates the first and the second gray scale voltage. A control block generates the first and the second loading polarity control signal and the demuxing latch signal.;COPYRIGHT KIPO 2010
