The embodiment of the invention provides a display panel driving method and a display device. The driving method comprises the following steps: generating a first time sequence signal comprising a plurality of first-type pulses; wherein the time sequence of the first type of pulses is located at the tail of the time sequence of the refresh frame, the pulse width of the first type of pulses is NH, and the value range of N is larger than or equal to 8 and smaller than or equal to 12; scanning an initial signal end of a first gate drive circuit of the display panel by using the first time sequence signal; wherein the output end of the first gate drive circuit is used for providing a control signal for a compensation transistor of the pixel circuit. By shortening the pulse width of the first type of pulse in the refresh frame, the high level charging time of the initial signal end of the first gate drive circuit is shortened, and the positive charges in the parasitic capacitance and the capacitor CQ are reduced, so that the node Q can be switched from the high level to the low level in time, and the poor display phenomenon of upper and lower split screens is improved.

This invention relates to the field of aluminum foil production technology, specifically a method for treating aluminum powder on the surface of rolled aluminum foil. This method effectively removes aluminum powder adhering to the aluminum foil surface by combining physical and chemical treatments, improving the purity and safety of the aluminum foil. It is applicable to industries such as electronics, electrical appliances, and food packaging. The treatment effect of aluminum powder can be further optimized by controlling static electricity elimination during the rolling process, selecting the cleaning solution, and using controlled atmosphere heat treatment conditions. Furthermore, the introduction of quality inspection ensures that there is no residual aluminum powder on the surface of the treated aluminum foil, improving product reliability and safety. This invention provides a new solution for quality control in the aluminum foil production process.
