Abstract: The present disclosure provides a display panel, the display panel includes a substrate, a light-emitting layer, a first refractive layer, and a second refractive layer. The first refractive layer is arranged on a side of the light-emitting layer away from the substrate. The second refractive layer covers a side of the first refractive layer away from the substrate and fills a plurality of openings of the first refractive layer. The second refractive layer extends from a display area to a non-display area and covers a bending area to protect wirings in the bending area, and the second refractive layer may replace a protective glue layer in prior art, which is beneficial to saving processes.

Abstract: Disclosed is a convenient hair dryer, comprising a body and a holder connected thereto, wherein the holder is configured to be reversibly and fast convertible between a handle configuration and a support configuration.
