Patent ID: 8279140

Claim:
A transflective liquid crystal display comprising: a top and a bottom substrate having a liquid crystal layer sandwiched between the top and the bottom substrate; plural pixels, each one of the plural pixels comprising: three reflective sub-pixels for displaying a reflective image, three reflective sub-pixels having a reflective layer on an inner surface of the bottom substrate to reflect an incident light back to a viewer; and a transmissive sub-pixel for displaying a transmissive image; at least one electronic circuit for driving the at least three reflective sub-pixels and the transmissive sub-pixel of each one of the plural pixels, the at least one electronic circuit comprising: a first and second scan electrodes; a first and second data electrodes, wherein the first scan electrodes and the plural first data electrode connect each one of the three reflective sub-pixels to the at least one electronic circuit and second scan electrodes and second data electrodes connect each one of the transmissive sub-pixel to the at least one electronic circuit; a reflective pixel electronic circuit connected with the first scan and first data electrodes for driving three reflective sub-pixels; and a dual-switch based transmissive pixel electronic circuit connected with the second scan and second data electrodes for driving the transmissive sub-pixel; a backlight below the transmissive sub-pixels; and a timing control unit connected with the at least one electronic circuit for converting and distributing an incoming video data to the plural pixels and controlling the backlight to synchronize the reflective and transmissive display images.
