Abstract
A pixel in a plurality of pixels in an LCD of a system comprises a transmissive part, a reflective part and a latched driving circuit. The driving circuit comprises a transmissive section comprising a transmissive data input coupled to the transmissive part of the pixel, and is configured to drive a transmissive data value from the transmissive data input and to set the transmissive part to a transmissive display state based on the transmissive data value; a reflective section comprising a reflective data input (independent of the transmissive data input) coupled to the reflective part of the pixel, and is configured to drive a reflective data value from the reflective data input and to set the reflective part to a reflective display state based on the reflective data value.
