Abstract:
1. A driving method of a display device comprising a source signal line and a pixel, the pixel comprising a first sub pixel and a second sub pixel, each of the first sub pixel and the second sub pixel comprising a first transistor, a SRAM, an electrophoresis element, and a pixel electrode, the method comprising the steps of: supplying a first voltage from the source signal line to the pixel electrode of the first sub pixel through the first transistor of the first sub pixel to store the first voltage to the SRAM of the first sub pixel and apply a first electric field corresponding to the first voltage to the electrophoresis element of the first sub pixel; and supplying a second voltage from the source signal line to the pixel electrode of the second sub pixel through the first transistor of the second sub pixel to store the second voltage to the SRAM of the second sub pixel and apply a second electric field corresponding to the second voltage to the electrophoresis element of the second sub pixel, wherein the SRAM of each of the first sub pixel and the second sub pixel comprises a second transistor and a third transistor, wherein the SRAM of each of the first sub pixel and the second sub pixel is electrically connected to the first transistor and the pixel electrode of corresponding one of the first sub pixel and the second sub pixel, wherein an area of the first sub pixel and an area of the second sub pixel are different from each other, wherein the pixel electrode of each of the first sub pixel and the second sub pixel covers the first transistor, the second transistor, and the third transistor of corresponding one of the first sub pixel and the second sub pixel, and wherein the electrophoresis element of each of the first sub pixel and the second sub pixel covers the first transistor, the second transistor, the third transistor, and the pixel electrode of corresponding one of the first sub pixel and the second sub pixel.
