Driving method for display panel

摘要

A driving method for a display panel is provided. The display panel includes at least a first common signal line, at least a second common signal line and a plurality of pixels arranged as a pixel array. The pixel array includes a first pixel row and a second pixel row electrically connected to the first common signal line and the second common signal line, respectively. The driving method includes steps of: generating a first AC common signal; generating a second AC common signal, wherein the first AC common signal and the second AC common signal are inverse to each other; and providing the first and second AC common signal to the first and second pixel rows through the first and second common signal lines, respectively, by way of N-frame switch, wherein N is a positive integer.

1. A driving method for a display panel, the display panel being a touch panel, having a fixed refresh rate, and comprising at least a first common signal line, at least a second common signal line and a plurality of pixels arranged as a pixel array, the pixel array comprising a first pixel row and a second pixel row electrically connected to the first common signal line and the second common signal line, respectively, all pixels of the first pixel row and the second pixel row being connected to a first scan line and a second scan line respectively, the driving method comprising:
generating a first AC common signal; generating a second AC common signal, wherein the first AC common signal and the second AC common signal are inverse to each other; providing the first and second AC common signals to all pixels of the first and second pixel rows through the first and second common signal lines, respectively, wherein one of the first and second AC common signals is configured to have one level switch within each N-frame switch, wherein the pulse width of the AC common signal enabling period of the N-frame switch is equal to the N times of the pulse width of the AC common signal enabling period of the 1-frame switch, and the first and second pixel rows have one polarity switch within each N-frame in accordance with the first and second AC common signals, and N is equal to or greater than two; and when the touch operation of the display panel is ended, changing from providing the first and second AC common signals by way of 1-frame switch to providing the first and second AC common signals by way of N-frame switch.
