The application relates to a beating machine for corrugated paperboard production, which comprises a tank body with a chamber in the inside, an inner cylinder is arranged in the chamber, a plurality of through holes are formed in the inner cylinder, a pulping crushing chamber is arranged in the inside of the inner cylinder, and a buffer chamber for storing paper pulp is formed in the outside of the inner cylinder by the inner cylinder; two fly cutter rollers are arranged in the inside of the buffer chamber and rotate oppositely, a driving element is arranged above the tank body, and a circulating unit is further arranged on the tank body; the beating machine can make the paper pulp in the buffer chamber return to the crushing chamber for circulating crushing for multiple times through cooperation of the driving element, the fly cutter rollers and the circulating unit, different raw materials with different particle sizes continuously receive the cutting action of the fly cutter rollers in the multiple circulating processes, the size difference of the raw material particles is effectively reduced, and the uniformity of the paper pulp is remarkably improved.

The embodiment of the invention provides a driving method of a display panel and the display panel, the display panel is provided with a display area and a light-transmitting area, the display panel comprises data lines and a plurality of pixel circuits arranged in an array, and each column of pixel circuits is connected with one data line. The number of the pixel circuits connected with the data lines corresponding to the light-transmitting area is smaller than that of the pixel circuits correspondingly connected with the data lines corresponding to the display area, and the pixel circuits are located in the display area; the driving method comprises the steps that in a display period, preset data voltage is transmitted to at least part of column data lines corresponding to at least part of row scanning periods in a light-transmitting area; wherein at least part of the lines include the last line of pixels corresponding to the light-transmitting area, and the preset data voltage is non-black state voltage. According to the scheme, the problem that a bright line extending upwards is generated at the junction of the light-transmitting area and the display area is effectively solved, and the display effect is further improved.
