ABSTRACT:
According to the present invention, improved techniques for switching current flow in a display column driver circuit. Embodiments provide switching of analog outputs of digital to analog converters in order to drive columns of an LCD. Embodiments can provide a full range of voltage output to drive an LCD without necessitating a full range amplifier configuration. Further, many embodiments can be realized in smaller space on an IC chip than in conventional technologies.
