Fingerprint image sensor and electronic device

The invention provides a fingerprint image sensor and an electronic device. The fingerprint image sensor is suitable for being arranged below the display panel and comprises a substrate and a plurality of photosensitive pixels. The plurality of photosensitive pixels are arranged on the substrate to form a photosensitive array with M rows and N columns. The photosensitive pixels located on each rowof the photosensitive array are arranged in the row direction, and the photosensitive pixels located on each column of the photosensitive array are arranged in the column direction. Each photosensitive pixel comprises a photoinduction area, and the photoinduction area is provided with a first area side edge and a second area side edge. An acute angle is formed between the side edge of the first area and the side edge of the second area and is larger than 0 degree and smaller than 90 degrees. 本发明提出一种指纹图像传感器与电子装置。指纹图像传感器适于配置于显示面板下方，并包括基底与多个感光画素。多个感光画素于基底上排列成M行N列的感光阵列。位在感光阵列的每一行上的感光画素沿着行方向排列，位在感光阵列的每一列上的感光画素沿着列方向排列。每一感光
