Abstract

The embodiment of the invention discloses an array substrate, a manufacturing method of the array substrate, a display panel and a display device. The array substrate comprises a substrate body, a plurality of light emitting units located on the substrate body and light sensing units arranged on the sides, close to the substrate body, of the light emitting units; each light emitting unit comprisesa first electrode and a light emitting layer, and the first electrodes are located between the substrate body and the light emitting layers; each first electrode comprises at least one hollowed-out area and a non-hollowed-out area surrounding the hollowed-out area; vertical projections of the light sensing units on the substrate body are at least partially overlapped with the vertical projectionsof the hollowed-out areas of the first electrodes on the substrate body. Compared with an existing array substrate, the array substrate can achieve the aim of improving the fingerprint identificationprecision of the array substrate or even the display panel.

Description

technical field [0001] The present invention relates to display technology, in particular to an array substrate, a manufacturing method of the array substrate, a display panel and a display device. Background technique [0002] Each person's skin texture varies in pattern, breakpoints and intersections, and is unique to an individual and remains the same throughout life. Accordingly, the true identity of each person can be verified through skin texture recognition technology. At the same time, the fingerprint formed on the surface of the end of an individual's finger is easy to obtain because of its texture characteristics, and the individual can usually be associated with its fingerprint. By comparing the acquired fingerprint with the pre-saved fingerprint data, the true identity of the individual can be verified. This is fingerprint identification technology. In recent years, thanks to the combination and development of electronic integrated manufacturing technology and ...
