Abstract:
The present disclosure generally relates to gamma bus wiring techniques that saves space in a display such as a liquid crystal display. In certain embodiments, a voltage offset associated with gamma bus amplifiers configured to provide analog voltage levels to a pixel may reduce at least some of the visual performance characteristics of the attached display when it transitions between different voltage values provided by different gamma bus amplifiers. The voltage offsets associated with the gamma bus amplifiers may be distributed between multiplexers that are coupled to gamma bus amplifiers by interlacing the wires routed from a resistor string to the multiplexers.
