Abstract: A license plate character recognition method and apparatus, an electronic device, and a storage medium. The method comprises: after obtaining a vehicle image captured by an image capturing device, positioning a vehicle plate area in the vehicle image to obtain a license plate image, and performing feature extraction on the license plate image by means of a convolutional neural network comprising a residual network structure. Gradient vanishing is effectively avoided and feature loss in a convolutional process of the convolutional neural network is reduced, so that a bidirectional recurrent neural network model can accurately recognize license plate characters in the license plate image on the basis of feature information of the license plate image. Therefore, character segmentation for a license plate is not needed, license plate characters on the license plate can be obtained by directly recognizing the whole license plate, segmentation and separate recognition for the license plate characters are avoided, and the recognition speed and the recognition accuracy are improved.

Abstract: Disclosed are an array substrate and a manufacturing method therefor, and a display apparatus, which relate to the technical field of display. The array substrate comprises a base substrate, a plurality of common electrodes, a plurality of data lines, and a plurality of pixel electrodes arranged in an array. With regard to each data line, the distance between the data line and a first target common electrode is different from the distance between the data line and a second target common electrode, such that two sides of each pixel electrode are subject to the same degree of interference, thereby ensuring that display areas in the array substrate that correspond to the two sides of the pixel electrode are consistent in brightness, and the display effect of the display apparatus is good. In addition, with regard to each data line, the distance between the data line and a first target pixel electrode is equal to the distance between the data line and a second target pixel electrode, wherein the first target pixel electrode and the second target pixel electrode are located on two sides of the data line, such that the coupling capacitances of the pixel electrodes on the two sides of the data line relative to the data line can be made the same, and the display effect of the display apparatus is good.
