Abstract
Official abstract text for this publication.
A liquid-crystal-driving circuit includes: resistors connected in series between first and second potentials lower than the first potential; one or more voltage follower circuits to impedance-convert one or more intermediate potentials between the first and second potentials, to be outputted, respectively, the intermediate potentials generated at one or more connection points between the resistors, respectively; a common-signal-output circuit to supply common signals to common electrodes of a liquid crystal panel, respectively, the common signals being at the first, second, or one or more intermediate potentials in a predetermined order; and a segment-signal output circuit supplies segment signals to segment electrodes of the liquid crystal panel, respectively, the segment signals being at the first and second potentials, or the intermediate potentials according to the common signals, wherein the segment-signal output circuit increases impedances of the segment signals only for a first period when the of segment signals potentials are switched.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid crystal driving circuit, comprising: a common-signal output circuit configured to supply common signals to common electrodes of a liquid crystal panel and configured to have one or more common nodes whose impedances can be changed, each of the common signals being at a first potential, a second potential, or one or more intermediate potentials in a predetermined order, wherein the common-signal output circuit includes first and second switch circu…
