Abstract

A light control device and a display device using the same. The light control device includes a polymer networked liquid crystal (PNLC) or polymer dispersed liquid crystal (PDLC) display switchable between a scattering state and a first display state, and a guest-host (G-H) liquid crystal display (LCD) switchable between a transparent state and a second display state. A light source of the G-H LCDis disposed at a side of the PNLC or PDLC display and aligned to its liquid crystal layer. In a first operational mode, the PNLC or PDLC display is switched to the first display state, and the G-H LCD is switched to the transparent state and becomes transparent. In a second operational mode, the G-H LCD is switched to the second display state, and the PNLC or PDLC display is switched to the scattering state to function as a light guide layer for the G-H LCD.

Description

technical field [0001] The present disclosure relates to display technology, and more particularly, to a light control device and a display device using the light control device. Background technique [0002] The background description provided herein is for the purpose of presenting the context of the present disclosure. In this disclosure, there is no explicit or implicit acknowledgement that the inventors' achievements mentioned in the background description and aspects of the specification are prior art, and they are not considered to be prior art prior to the filing date. [0003] In a display device, features for controlling light may be included that enable the display device to switch between different display modes, including a display mode for bright environments (eg, outdoor areas during the day or bright rooms) , in which the display device can use external light from the environment, and another display mode suitable for dark environments with low ambient light...
