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 display panel, comprising:
- a first signal line;
- a first data line;
- a first scan line interlaced with the first data line;
- a second scan line interlaced with the first data line and paralleled with the first scan line, wherein the first and second scan lines receive first and second scan signals respectively;
- a first pixel coupled to the first data line and the first scan line;
- first and second switching elements directly connected in series between the first data line and the first signal line;
- a first storage capacitor coupled between first terminals of the first and second switching elements and a ground;
- third and fourth switching elements directly connected in series between the first data line and a second signal line, wherein the first signal line and the second signal line receive different signals, respectively;
- and
- a second storage capacitor coupled between first terminals of the third and fourth switching elements and the ground,
- wherein a control terminal of the first switching element is coupled to a first control signal and a control terminal of the third switching element is coupled to a second control signal different from the first control signal, and control terminals of the second and fourth switching elements are coupled to a third control signal different from the first and second control signals;
- wherein the first switching element is turned on by the first control signal when the first scan signal is activated, and the third switching element is turned on by the second control signal when the second scan signal is activated.

A display panel, comprising:
- a first signal line;
- a first data line;
- a first scan line having an odd scan line and an even scan line for receiving an odd scan signal and an even scan signal respectively;
- a first pixel coupled to the first data line and the first scan line;
- first and second switching elements directly connected in series between the first data line and the first signal line;
- a first storage capacitor coupled between first terminals of the first and second switching elements and a ground;
- third and fourth switching elements directly connected in series between the first data line and a second signal line, wherein the first signal line and the second signal line receive different signals, respectively;
- and
- a second storage capacitor coupled between first terminals of the third and fourth switching elements and the ground,
- wherein a control terminal of the first switching element is coupled to a first control signal which turn on the first switching element in step with the odd scan signal and a control terminal of the third switching element is coupled to a second control signal which turn on the third switching element in step with the even scan signal.
