Patent ID: 7542024

Claim:
An electrophoresis display device comprising: a source signal line, and a pixel region including at least a first sub pixel, a second sub pixel, and a third sub pixel, the first sub pixel comprising: a first pixel electrode, a first thin film transistor, a first plurality of microcapsules and a first SRAM connected between the first pixel electrode and the first thin film transistor; the second sub pixel comprising: a second pixel electrode, a second thin film transistor, a second plurality of microcapsules and a second SRAM connected between the second pixel electrode and the second thin film transistor, the third sub pixel comprising: a third pixel electrode, a third thin film transistor, a third plurality of microcapsules and a third SRAM connected between the third pixel electrode and the third thin film transistor, wherein the first sub pixel, the second sub pixel, and the third sub pixel share the source signal line, wherein the first plurality of microcapsules are provided adjacent to the first pixel electrode, and a plurality of charged particles are embedded in the first plurality of microcapsules, wherein areas of the at least first sub pixel, second sub pixel, and third sub pixel are different from each other, wherein the first SRAM comprises a fourth thin film transistor and a fifth thin film transistor, and wherein the first pixel electrode is covering all of the first thin film transistor, the fourth thin film transistor and the fifth thin film transistor, and the first plurality of microcapsules are over the first pixel electrode, and all of the first thin film transistor, the fourth thin film transistor and the fifth thin film transistor.
