  • Patent number: 10409106
    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.
