We combined a photochromic film with an optically switchable transparent display. The display consists of a PNLC and light sources. Post ultraviolet irradiation, the PNLC and photochromic films changed from the initial transparent state to the screen and dimming states, respectively. Photochromic films block background light and improve contrast ratio.
