smart screen
october 2017
Windows are an essential tool within our built environment that both protect inhabitants from the natural elements while also transmitting light and visibility. They create a relationship between adjacent spaces that explores the dichotomy of interior and exterior; public and private; visibility and invisibility; and light and shadow. Using technology, SMART SCREEN poetically plays with this dichotomy based on the user’s needs and preferences.

SMART SCREEN is an independent research project that I've been working on.

SMART SCREEN can change its opacity at varying degrees to accomodate situational needs in privacy and lighting. When sunlight is absent, SMART SCREEN can also provide lighting dependent on situational needs.
PDLC (Polymer Dispersed Liquid Crystal) film or more commonly known as smart film consists of a thin film of liquid crystal that sits between two conductive transparent plastic layers. It has the ability to change its properties and appearance by changing the current running through the liquid crystal. During its “off” state, the liquid crystals are in a disordered, misaligned state that prevents light from penetrating the film, rendering it opaque. When a voltage between 24 to 100 volts are applied the crystals are arranged to allow light to pass through delivering a transparency between 55% to 85%. By controlling the amount of voltage applied, the degrees of transparency in smart film can be controlled.
