Abstract: An attention mechanism-based 12-lead electrocardiogram (ECG) classification method is described, the method including acquiring an original image of a 12-lead ECG, segmenting waveform data recorded in the original image to obtain segmented waveform data for each lead in the 12-lead ECG, performing depth feature extraction on the segmented waveform data of said each lead to obtain a first feature map of said each lead, performing feature transformation on the first feature map of said each lead based on an attention mechanism to obtain a depth feature of said each lead, and classifying the depth feature of said each lead to obtain a classification result for the original image. The classification method can make full use of the 12-lead ECG for overall classification and improve the accuracy of image classification.

Abstract: A display substrate (910), including a flexible substrate body, a thickness adjustment layer (71), and a micro-lens layer (72). The flexible substrate body includes: a plurality of island-shaped display regions (100) spaced apart from each other, a hollow region (300) disposed between adjacent island-shaped display regions (100), and a connection region (200) for connecting the adjacent island-shaped display regions (100). The thickness adjustment layer (71) is disposed on light exit sides of the plurality of island-shaped display regions (100) of the flexible substrate body. The micro-lens layer (72) is disposed on the side of the thickness adjustment layer (71) away from the flexible substrate body.
