Abstract
An optical sensor, method of making the same, and a display panel having an optical sensor. The optical sensor includes a first electrode, a second electrode, a photosensitive silicon-rich dielectric layer, and a first interfacial silicon-rich dielectric layer. The photosensitive silicon-rich dielectric layer is disposed between the first and second electrodes. The first interfacial silicon-rich dielectric layer is disposed between the first electrode and the photosensitive silicon-rich dielectric layer.
