Benefits of technology

This patented technology describes an improved way to make displays with better efficiency when exposed to sunlight without losing their effectiveness due to reflection from other layers inside them (such as electrodes). By placing this antireflective coating closer towards the edge of the substrate containing these components, it becomes more effective against reflected lights compared to traditional ways like adding extra materials around the edges.

Problems solved by technology

The technical problem addressed in this patented technology relates to improving the efficiency or lifespan (lifetime) of oxide semi-conductive field effect devices used for signal processing purposes during their lifetime when exposed to different levels of brightness compared with other types of device such as silicon integrated circuit chips that are less sensitive to light exposure.

Abstract

The invention provides a display panel, a manufacturing method thereof and a display device. The display panel comprises a substrate and a thin film transistor layer, wherein the thin film transistor layer is located on the substrate and comprises an active layer, a metal layer and an anti-reflection layer; the anti-reflection layer is at least located on the side, close to the active layer, of the metal layer; and the reflectivity of the anti-reflection layer is smaller than that of the metal layer. According to the display panel, light irradiated to the active layer can be reduced, the risk of failure caused by performance change of the thin film transistor layer is reduced, and the working stability and reliability of the thin film transistor layer are improved.
