This invention discloses an electronic paper display panel and a display device. The display panel includes: multiple data lines and multiple scan lines; and sub-pixels enclosed by the multiple data lines. The data lines are serpentine, with two data lines between adjacent columns of sub-pixels. Each pair of adjacent rows of sub-pixels is connected to a scan line, and within the same column, each pair of sub-pixels is not completely enclosed by two data lines. The two rows of sub-pixels are respectively connected to left and right data lines. The display panel provided by this invention, by setting the data lines in a serpentine pattern, with at least a portion of adjacent columns of sub-pixels having two data lines between them; each pair of adjacent rows of sub-pixels is connected to a scan line, and within the same column, each pair of sub-pixels is not completely enclosed by two data lines. The two rows of sub-pixels are respectively connected to left and right data lines. This reduces the intersection of signal lines on the bottom bezel of the electronic paper display panel, saves costs, facilitates the realization of a narrow bezel in the electronic paper display panel, and improves the display effect.

The application discloses a display panel driving method and a display device. The display panel driving method comprises the following steps: obtaining a display scene of a video source signal; when the display scene of the video source signal is a target display scene, sequentially and alternately charging first to i-th sub-pixels, and charging the sub-pixels of one color in each frame display period of the video source signal, thereby increasing the charging time of the sub-pixels, and relieving the problem of uneven display panel picture brightness caused by insufficient charging of the sub-pixels.

The application provides an array substrate, a driving method and a display device. The array substrate comprises a driving module, a plurality of rows and columns of sub-pixels, a plurality of columns of data lines and a plurality of rows of scanning lines; one frame time comprises at least two sub-frames; the driving module provides scanning signals to the scanning lines, controls the plurality of rows of scanning lines to be opened in turn in the sub-frames, and controls the sub-pixels corresponding to the same color and electrically connected to the opened scanning lines and the same data line in the sub-frames; in the sub-frames, there are overlapping time periods and non-overlapping time periods between effective time periods of scanning signals provided by at least two adjacent scanning lines in the plurality of rows of scanning lines opened in turn; and data voltages received by the data line in at least part of the overlapping time periods are the same as data voltages received by the data line in at least part of the non-overlapping time periods. The application can improve the charging time of at least part of the sub-pixels, improve the charging rate and the refresh rate, and improve the display quality.

The invention discloses a charging pile cluster power intelligent distribution method and device, electronic equipment and a medium, and belongs to the technical field of charging. The method comprises the steps that the current battery electric quantity and the maximum battery capacity of a vehicle connected to a charging pile are acquired; calculating the priority weight of the vehicle according to the current electric quantity of the battery and the maximum capacity of the battery; determining the charging power allocated to the vehicle according to the priority weight and the maximum supply power of the charging pile cluster; the higher the priority weight is, the larger the charging power distributed to the vehicle is. By acquiring the current electric quantity and the maximum capacity of the vehicle battery, the charging demand of the vehicle can be accurately known, the priority weight of the vehicle is calculated according to the data, the emergency degrees of different vehicles to charging can be distinguished, the charging power is distributed according to the actual demand of the vehicle, and the charging efficiency is improved. Therefore, the vehicles with high priority weights can obtain more charging power, so that reasonable distribution of the charging power is realized, and the energy utilization rate and the charging efficiency of the whole charging pile cluster are improved.
