Patent ID: 8462144

Claim:
A multi-mode display system comprising: a multi-mode liquid crystal display comprising a plurality of pixels, a first pixel in the plurality of pixels comprising a first transmissive part and a first reflective part; a latched pixel driving circuit comprising: a transmissive latching section comprising a first transmissive data input coupled to the first transmissive part of the first pixel, wherein the transmissive latching section is configured to drive a first transmissive data value from the first transmissive data input and to set the first transmissive part to a first transmissive display state based on the first transmissive data value from the first transmissive data input; a reflective latching section comprising a first reflective data input coupled to the first reflective part of the first pixel, wherein the reflective latching section is configured to drive a first reflective data value from the first reflective data input and to set the first reflective part to a first reflective display state based on the first reflective data value from the first reflective data input; wherein the first transmissive part comprises a first capacitor formed in part by a portion of a liquid crystal material in the first transmissive part; wherein the first transmissive part further comprises a second capacitor connected in parallel with the first capacitor and configured to maintain a charged state of the first capacitor; and wherein the first capacitor and the second capacitor are separate from the transmissive latching section.
