The invention discloses an array substrate and a preparation method thereof, and a display device, wherein the array substrate is used for reducing grain recognition light propagation paths and improving grain recognition accuracy and efficiency. The array substrate comprises: a substrate body; a display area and a peripheral area, wherein the display area comprises a first thin film transistor onthe substrate, a first connecting lead wore electrically connected with the first thin film transistor on the substrate, a packaging layer located on the first thin film transistor, a photosensitivedevice located on the packaging layer, and a second connecting lead wire located on the packaging layer and electrically connected with the photosensitive device, the first connecting lead wire, the second connecting lead wire and the packaging layer all extend to the peripheral area, the peripheral area comprises a retaining wall positioned between the first connecting lead wire and the packaginglayer, the packaging layer covers the retaining wall, the packaging layer is provided with a first via hole exposing the first connecting lead wire on the side, deviating from the first thin film transistor, of the retaining wall, and the second connecting lead wire is electrically connected with the first connecting lead wire through the first via hole.
Description
technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting display devices not only have diversified application fields, but also some products are gradually becoming multi-functional, such as display products with a fingerprint recognition function. At present, optical fingerprint recognition has become one of the most important means of realizing fingerprint recognition of display products. However, in the display products of the prior art, the distance between the optical fingerprint recognition module and the screen surface is relatively long, and the light propagation path is long, which affects the definition of the fingerprint image and affects the accuracy of fingerprint recognition. Contents of the invention [0003] Embodiments of the present application provide an array substrate, a manuf...
