Abstract
Display panels buffering display data from a data driver. The display panel comprises a first signal line, a first data line, a first scan line interlaced with the first data line, a first pixel coupled to the first data line and the first scan line, a first switching element comprising a first terminal coupled to the first data line, a first storage capacitor coupled between a second terminal of the first switching element and a ground, and a second switching element coupled to the first storage capacitor and the first signal line.
Claims6
A method for driving a display panel, comprising:
- transferring a first set of data stored in N first storage capacitors in a M−1th period to N corresponding first pixels through N data lines, so as to drive the N corresponding first pixels, and storing a second set of data on a second signal line from a data driver to N second storage capacitors, during an Mth period;
- transferring the second set of data stored in the N second storage capacitors to N corresponding second pixels through the N data lines, so as to drive the N corresponding second pixels, and storing a third set of data on a first signal line from the data driver to the N first storage capacitors, during an M+1th period;
- and
- transferring a fourth set of data on the first signal line from the data driver to N first storage capacitors through the N data lines, such that the N corresponding first pixels are driven by the first and fourth sets of data, during the Mth period;
- wherein the first signal line is different from the second signal line;
- wherein the second set of data on the second signal line is stored in the N second storage capacitors in sequence during the Mth period, and wherein the third set of data on the first signal line is stored in the N first storage capacitors in sequence during the M+1th period;
- and
- wherein M and N are integers larger than 2.
