摘要 |
In the signal electrode drive apparatus for use in a liquid crystal display, the signal electrode drive circuit (3a) for driving a liquid crystal display panel (LCD) is comprised of a latch circuit (2l) for latching a digitized video signal, a buffer (22), a graduation signal-forming circuit (23), an intensity modulation pulse-generating circuit (25), and an analog multiplexer (24). The latch circuit (2l) holds the video data only once during one horizontal scanning period till the next latch pulse M is generated, thus considerably reducing current dissipation. |
