Abstract: Embodiments of the present invention disclose a polarizer, a display panel and a display device. A flexible electrode layer in the polarizer is located between an adjacent polarizing layer and one functional film layer or located between two adjacent functional film layers. Specifically, the polarizer provided by embodiments of the present invention adds a flexible electrode layer in the structure of the polarizer, thereby enabling the polarizer to have both the optical function of a conventional polarizer and the additional flexible electrode function. When the multifunctional polarizer is applied in a display device, the functions of electrostatic shielding and protecting the display device can be achieved. Particularly, when the multifunctional polarizer is applied in an In Plane Swtiching (IPS) liquid crystal display device, it can replace the shielding electrode structure at the color film substrate side so as to implement the function of electrostatic shielding.

Abstract: A camera system includes an image sensor assembly and a tunable optical element. The tunable optical element is a polymer dispersed liquid crystal lens doublet using a PDLC layer. The doublet is tunable by applying an electric field to the optical element via a control element. The control element applies a voltage differential to the optical element inducing an electric field which changes the polarization of the PDLC within the optical element. The refractive index of the lens doublet is dependent on the polarization of the liquid crystals within the optical element. Applying the electric field to the tunable element changes the optical properties of the lens doublet.
