Abstract:
1. A drive method for driving a liquid crystal display, wherein said liquid crystal display comprises: a plurality of data lines; a plurality of scan lines crossing said data lines; a plurality of pixels defined by two neighboring data lines and two neighboring scan lines crossing the two neighboring data lines, wherein each pixel comprises: a first pixel electrode; a second pixel electrode; a common electrode, wherein said common electrode and said first pixel electrode define a first sub-pixel and said common electrode and said second pixel electrode define a second sub-pixel; a first transistor located in said first sub-pixel, a gate electrode of said first transistor is connected to said first scan line, a first source/drain electrode of said first transistor is connected to said first data line and a second source/drain electrode of said first transistor is connected to said first pixel electrode, wherein the first pixel electrode receives a data signal from the first data line through the first transistor; a second transistor located in said second sub-pixel, a gate electrode of said second transistor is connected to said second scan line and a second source/drain electrode of said second transistor is connected to said second pixel electrode; and a third transistor located between two adjacent pixel, a gate electrode of said third transistor is connected to said first scan line, a second source/drain electrode of said third transistor is connected to a first source/drain electrode of said second transistor and a first source/drain electrode of said third transistor is connected to said first data line, wherein said second transistor is coupled to said first data line through said third transistor, wherein the second pixel electrode receives a data signal from the first data line through the second transistor and the third transistor, said method comprises: providing pulse signals to said scan lines sequentially, wherein a time difference exists between two pulse signals providing to adjacent scan lines; and providing two-step signals to said data lines sequentially, said two-step signal includes a first voltage signal and a second voltage signal, wherein said first voltage signal is written to said first sub-pixel through said first transistor when said first and second scan line are driven together, and said second voltage signal is written to said second sub-pixel through said second transistor and said third transistor when said first scan line is not driven and said second scan line and adjacent pixel's first scan line are driven.
