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 display panel driving method, suitable for a display panel with multiple gate lines, the driving method includes: driving the multiple gate lines in a first preset order and a second preset order in turn, wherein the first preset Suppose the order is from the first gate line to the end of the last gate line, the second preset order is from the last gate line to the end of the first gate line, and every two adjacent gate lines There is partial overlap during driving; and when driving the plurality of gate lines in a first predetermined order or a second predetermined order, changing the high and low of each gate pulse provided to the plurality of gate lines Potential pressure difference. The display panel driving method of the present invention reduces the set number of gamma voltages and common voltages by increasing the feedthrough voltage generated by the gate lines during forward scanning and reducing the feedthrough voltage generated during reverse scanning.
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...
