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...
