LIQUID CRYSTAL SWITCHING BARRIER THERMAL CONTROL

摘要

A polymer dispersed liquid crystal layer applied to the display screen for an electronic device is described herein. The polymer dispersed liquid crystal applied to the display screen is operable to switch between a transparent state and a translucent and/or opaque state. In the transparent state the display screen is viewable as usual. In the translucent and/or opaque state the liquid crystal prevents incident solar radiation from heating up the internal components of the device.

主权项

1. A device comprising:
a cover window protecting an internal hardware element; a display stack underlying the cover window; and a polymer dispersed liquid crystal (PDLC) layer positioned adjacent to the cover window; wherein the PDLC layer is operable in a first state and a second state; the PDLC layer is in communication with the internal hardware; and the internal hardware element provides at least one of a switching signal or power supply for applying an electric field to the PDLC layer.
