Privacy screen device and display having same

Abstract

A display includes a frame, a display panel and a privacy screen device. The frame includes two first sides and two second sides. The privacy screen device includes an engaging portion secured on one second side, a privacy screen unit and a guiding portion secured on the two first sides. The privacy screen unit includes a receiving portion secured on another second side, a privacy screen sheet and an engaging member. The engaging member is attached to the privacy screen sheet. The privacy screen sheet is wrapped around the receiving portion. When the engaging member engages with the engaging portion, the privacy screen sheet is at a deployed position where the privacy screen sheet unrolled and covers the display panel. When the engaging member is released from the engaging portion, the privacy screen sheet moves from the deployed position to a roll-up position where the display panel is entirely exposed.
