<p>An LCD signal driver system and circuit are provided. Current sharing may be utilized both at a system level and within the signal driver circuit in order to reduce power consumption. The system and circuit permit the use of a selectable data bus width, for example a single width or double width mode. The decoder architecture utilized allows multiplexing of two channels and eliminates the need for high voltage and low voltage circuitry for each column driver output. The outputs of the driver lines may be precharged to improve power usage and voltage transient characteristics. An improved level shifting circuit having outputs of varying voltage ranges may also be utilized. A decoder architecture is utilized in which the number of decoder cells per channel may be reduced by a factor of two. Improved data gating and feedback gating are also provided through the use of an improved decoder cell. The decoder cell may operate over a wide voltage range and may utilize an inherent level shifting and latch/reset function.</p> |
