Abstract

The embodiment of the invention discloses a PDLC (Polymer Dispersed Liquid Crystal) display panel. The PDLC display panel comprises a first transparent substrate, a second transparent substrate opposite to the first transparent substrate, a first electrode layer e, a second electrode layer, a PDLC layer, and a photochromic layer, wherein the first electrode layer is arranged on the side, near the second transparent substrate, of the first transparent substrate; the second electrode layer is arranged on the side, near the first transparent substrate, of the second transparent substrate, and comprises a plurality of second sub-electrodes arranged in a matrix; the PDLC layer is arranged between the first electrode layer and the second electrode layer; the photochromic layer is arranged on the side, far away from the PDLC layer, of the second transparent substrate. The embodiment of the invention further discloses a PDLC display device including the PDLC display panel and a driving method of the PDLC display device.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular to a polymer dispersed liquid crystal (PDLC, Polymer Dispersed Liquid Crystal) display panel, a PDLC display device and a driving method thereof, which are especially used for transparent display and color display. Background technique [0002] Generally, a liquid crystal display device utilizes the optical anisotropy and birefringence properties of liquid crystal molecules to display images, which generally requires polarizers, alignment layers, etc. to be disposed therein. However, such polarizers, alignment layers, etc. tend to cause relatively serious optical loss, shading, and the like. [0003] To this end, it has been proposed to use a PDLC display device. PDLC is formed by mixing small-molecule liquid crystals and prepolymers, and polymerizing under certain conditions to form micron-sized liquid crystal droplets and disperse them uniformly in the polymer networ...
