VOLTAGE CONVERSION APPARATUS SUITABLE FOR A PIXEL DRIVER AND METHODS

摘要

Apparatus and methods are disclosed that can provide for voltage translation and conversion that can be applied, as an example, in a microdisplay including a plurality of pixels that are driven at a pixel drive voltage. A pixel is configured to receive a lower pixel drive voltage for one state of the pixel and an upper pixel drive voltage for an opposite state of the pixel. A memory circuit selectively couples the pixel to the lower voltage and the upper pixel drive voltage in response to control signals operable between the lower voltage and an intermediate voltage level that is less than the upper pixel drive voltage.
