1results about How to "Improve light extraction rate" patented technology

This invention provides a display panel and a display device. The display panel includes a first optical refractive layer and a second optical refractive layer. The first optical refractive layer includes multiple openings, and the second optical refractive layer fills the multiple openings. The refractive index of the second optical refractive layer is greater than that of the first optical refractive layer. Nanoparticles are also disposed within the second optical refractive layer. When light passes through, the first and second optical refractive layers effectively increase the light transmittance. Simultaneously, the nanoparticles further act on the light, thereby effectively improving the light extraction rate of the display panel and enhancing its display effect.
