Abstract

The invention discloses a flexible light guide plate and a flexible display. The flexible light guide plate includes: a transparent substrate, the transparent substrate includes a first substrate and a second substrate; a transparent electrode, the transparent electrode includes a first electrode and a second electrode, and the first electrode It is arranged on the surface of the first substrate facing the second substrate, the second electrode corresponds to the first electrode, and is arranged on the surface of the second substrate facing the first substrate; the PDLC layer, the PDLC layer is arranged on the first substrate and the second substrate between. In the present invention, by adjusting the size of the scattering dots formed by the PDLC layer in the open state, the display can maintain better backlight uniformity even in the curved state.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible light guide plate and a flexible display. Background technique [0002] PDLC is a polymer-dispersed liquid crystal, also known as a liquid crystal dimming film. It is a mixture of low-molecular liquid crystals and prepolymer glue, and undergoes polymerization under certain conditions to form micron-sized liquid crystal droplets that are evenly dispersed in the polymer network. Among them, the dielectric anisotropy of liquid crystal molecules is used to obtain materials with electro-optic response characteristics. In existing applications, PDLC is used as a light guide plate, and the uniformity of the flexible backlight is improved through a special graphic design, such as figure 1 as shown, figure 1 a is a schematic diagram of the total reflection principle of PDLC in the off state, figure 1 b is the schematic diagram of the total reflection principle of PDLC in th...
