Abstract
The present application provides a driving circuit for display panel, which comprises a driving-signal generating circuit generating a driving signal in a frame time for driving a display element of a display panel. The driving signal includes at least one first turn-on pulse width, at least one first turn-off pulse width, at least one second turn-on pulse width, and at least one second turn-off pulse width. The first turn-on pulse width is greater than the second turn-on pulse width. The first turn-off pulse width is smaller than the second turn-off pulse width. By adopting the driving circuit according to the present application, EMI may be reduced and the displaying quality may be improved.
Claims17
A driving circuit for a display panel, comprising:
- a driving-signal generating circuit, generating a driving signal in a frame time to drive a display element of said display panel, said driving signal including at least one first pulse width, at least one second pulse width, and at least one third pulse width, said first pulse width greater than said second pulse width and said third pulse width, said second pulse width greater than said third pulse width;
- wherein in a duration within said frame time, said driving-signal generating circuit first generates said second pulse width before generating said first pulse width or said third pulse width.
A driving circuit for a display panel, comprising:
- a driving-signal generating circuit, generating a driving signal in a frame time for driving a display element of said display pane, said driving signal including at least one first turn-on pulse width, at least one first turn-off pulse width, at least one second turn-on pulse width, and at least one second turn-off pulse width, said first turn-on pulse width greater than said second turn-on pulse width, and said first turn-off pulse width smaller than said second turn-off pulse width.
A driving circuit for a display panel, comprising:
- a driving-signal generating circuit, generating a driving signal including a plurality of first pulse widths in the (F−1)th frame time for driving a display element of said display panel and a driving signal including a plurality of second pulse widths in the Fth frame time for driving said display element;
- wherein said second pulse widths are different from said first pulse widths;
- the duration of the (F−1)th frame time is identical to the duration of the Fth frame time;
- and F is an integer greater than 2.
