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.

Provided are an array substrate and a manufacturing method therefor, a display panel, and a display device. The array substrate includes: a plurality of electrodes arranged in an array. The electrode includes a plurality of strip electrodes that are connected to each other and spaced. The plurality of strip electrodes at least have two thicknesses. A distance between two adjacent strip electrodes is less than a preset value. During manufacturing, a mask used for forming each layer of sub-electrodes includes a plurality of strip-shaped shading regions that are connected to each other and spaced in a first direction. Strip-shaped shading regions in a mask used for sub-electrodes formed subsequently are integrally shifted by a first distance in the first direction relative to strip-shaped shading regions in a mask used for sub-electrodes formed last time.
