Problems solved by technology
When the gate drive circuit scans the gate line in the reverse direction, the data voltage stored in the pixel circuit will be more affected by the feed-through voltage than in the forward scan, so it is necessary to set different gamma voltages and common voltage to compensate the feedthrough voltage during forward and reverse scanning respectively. This method not only requires multiple sets of gamma voltage and common voltage settings, but also when the adjustment range of gamma voltage and common Large, it will also consume extra tuning time (tuning time)

Embodiment Construction
[0024] figure 1 It is a schematic diagram of gate line configuration of a display panel according to an embodiment of the present invention. Such as figure 1 As shown, the display panel 100 has a plurality of gate lines, and the odd-numbered gate lines (as shown by reference numerals G[1], G[3]...G[K-1]) among these gate lines are all Electrically coupled to the gate drive circuit 101, and the even-numbered gate lines (as shown by reference signs G[2], G[4]...G[K]) among these gate lines are electrically coupled connected to the gate drive circuit 102. In addition, the display panel 100 is electrically coupled to the source driving circuit 103 located on the lower side thereof. The odd-numbered gate lines G[1], G[3]...G[K-1] and the even-numbered gate lines G[2], G[4]...G[K] are arranged alternately, and the gate The driving circuits 101 and 102 are disposed on two opposite sides of the display panel 100 . In particular, if the above-mentioned gate lines are sequentially ...

A driving method for a display panel is suitable for a display panel with a plurality of gate lines. The driving method comprises that the plurality of gate lines are driven in a first preset sequence and a second preset sequence in turn, the first preset sequence starts from the first gate line to the final gate line, the second preset sequence starts from the final gate line to the first gate line, and the driving periods of any two adjacent gate lines are partly overlapped, and the differential voltage between a high potential and a low potential of each gate pulse supplied to the plurality of gate lines is changed when the plurality of gate lines are driven in the first preset sequence or the second preset sequence. In the driving method for the display panel, feed-through voltages generated when the gate lines carry out forward scanning are increased, feed-through voltages generated when the gate lines carry out reverse scanning are reduced, and therefore the set number of groups of gamma voltages and common-mode voltages is reduced.
Description
technical field [0001] The invention relates to a method for driving a display panel, in particular to a method for driving a gate line of the display panel. Background technique [0002] The gate drive circuit used for small-sized display panels usually adopts a bilateral single-drive architecture because of the panel configuration, that is, there are a set of independent gate drive circuits on the left and right sides of the display panel. The odd-numbered gate lines and the even-numbered gate lines in the display panel are respectively driven. In addition, a source driving circuit is arranged on the upper side or the lower side of the display panel to provide data voltages to each pixel in the display panel. If the source driving circuit is arranged on the upper side of the display panel, when the above-mentioned gate driving circuit drives the above-mentioned gate lines sequentially from top to bottom, this driving method is called reverse scanning; When the above-ment...
