Abstract
The present application discloses a pixel driving method, comprising: in a pre-charging phase, turning on a second driving branch to write a preset voltage into a second data line, and then turning off the second driving branch and turning on a first driving branch to write the preset voltage into a first data line; in a first data writing phase, keeping the first driving branch to be turned on to write a first data voltage into the first data line, and then turning off the first driving branch; and in a second data writing phase, turning on the second driving branch to write a second data voltage into the second data line.
Claims12
A pixel driving method applied to a display panel comprising pixels in N rows and 2M columns and 2M data lines respectively coupled to the 2M columns of pixels, the display panel further comprising M multiplexers each of which is coupled to two data lines of the 2M data lines and has a first driving branch coupled to a first one of the two data lines and a second driving branch coupled to a second one of the two data lines, the pixel driving method comprising:
- for each of the multiplexers,
- in a pre-charging phase, turning on the second driving branch to write a preset voltage into the second data line, and turning off the second driving branch and turning on the first driving branch after the preset voltage written into the second data line is stable to write the preset voltage into the first data line;
- in a first data writing phase, keeping the first driving branch to be turned on to write a first data voltage into the first data line, and turning off the first driving branch after the first data voltage written into the first data line is stable;
- and
- in a second data writing phase, turning on the second driving branch to write a second data voltage into the second data line.
