Title:
VIEWING ANGLE SWITCHABLE LIQUID CRYSTAL DISPLAY DEVICE AND VIEWING ANGLE SWITCHING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/027802
Kind Code:
A1
Abstract:
Provided are a viewing angle switchable liquid crystal display device and a viewing angle switching method. The liquid crystal display device comprises a display panel (10) and a backlight (30). The liquid crystal display device further comprises a light adjusting liquid crystal film (20) between the display panel (10) and the backlight (30). The light adjusting liquid crystal film (20) comprises an upper substrate (21), a lower substrate (22) opposite to the upper substrate (21), and a liquid crystal layer (23) located between the upper substrate (21) and the lower substrate (22). The upper substrate (21) is provided with an upper electrode (211) on a side facing the lower substrate (22). The lower substrate (22) is provided with a lower electrode (221) on a side facing the upper substrate (21). By applying a voltage between the upper electrode (211) and the lower electrode (221), the light adjusting liquid crystal film (20) can change a backlight emitting angle of the light emitted by the backlight (30) after passing through the display panel (10).
