Abstract:
Embodiments of the invention relate to a configurable LCD driver system having a plurality of configurable LCD drivers. Each LCD driver may be configured as a common or segment driver by selecting a drive voltage from an appropriate set of drive voltages associated with a common or segment driver in accordance with certain parameters, such as whether a user may configure the LCD driver as a common driver or segment driver, a multiplex ratio, and/or bias ratio of an LCD panel. The drive time and drive strength associated with the LCD driver may also be configurable. The selected drive voltage may be provided to a drive buffer to output an LCD drive voltage waveform for driving one or more segments or pixels in an LCD panel. A memory may store appropriate display data for both the segment and common drivers to control the output drive capability of the LCD driver.
