Abstract: The present invention discloses an array substrate and a method for preparing the same, and a display device. The array substrate comprises a substrate, and a thin-film transistor and a passivation layer formed on a side of the substrate, and the array substrate is divided into a reflective region and a transmissive region, wherein an insulating layer is formed on the reflective region on a side of the passivation layer that is far from the substrate, and a nanoparticle layer for diffuse reflecting an incident light is formed on a side of the insulating layer that is far from the substrate. Not only the viewing angle of the array substrate is enlarged, but also the performances of the array substrate such as transmittance, contrast and dark-state uniformity are guaranteed, thus the present invention is especially applicable for display devices for large-scale outdoor display.

Abstract: The present disclosure provides a display panel, an operating method thereof and a display device. The display panel includes first substrate and second substrate disposed opposite to each other, liquid crystal layer disposed between first substrate and second substrate, orthogonal polarization layer disposed on a side of first substrate facing towards liquid crystal layer, and first absorbent layer disposed on a side of first substrate facing away from liquid crystal layer. When no electric field is loaded, both liquid crystal layer and orthogonal polarization layer transmit light with first polarization direction. When electric field is loaded, liquid crystal layer converts incident light with first polarization direction into emergent light with second polarization direction which is orthogonal to first polarization direction, and the orthogonal polarization layer reflects the light with the second polarization direction. The first absorbent layer absorbs the light incident thereon.
