Abstract

A viewing angle control device including a plurality of first polarizing portions and a plurality of transmissive portions is provided. The first polarizing portions are arranged along a first direction and extended in a second direction. The transmissive portions and the first polarizing portions are alternately arranged. Each of the first polarizing portions has a width in the first direction and a height in a direction perpendicular to the first direction and the second direction. A ratio of the height to the width of the first polarizing portion is greater than 1. A display apparatus adopting the viewing angle control device is also provided. The viewing angle control device and the display apparatus provided herein have a filter effect at a large viewing angle, improved light transmittance in the viewing angle direction, and excellent anti-peeping performance.

Description

technical field [0001] The present invention relates to a viewing angle control technology, and in particular to a viewing angle controller and a display device. Background technique [0002] Generally speaking, in order to allow multiple viewers to watch together, a display device usually has a display effect with a wide viewing angle. However, in some situations or occasions, such as browsing private webpages, confidential information or entering passwords in public, the display effect of the wide viewing angle makes the confidential information easy to be peeped by others, resulting in leakage of the confidential information. In order to achieve the anti-peeping effect, it is common practice to place a Light Control Film (LCF) in front of the display panel to filter out light from large angles. On the contrary, when there is no anti-peeping requirement, the light control film is manually removed from the front of the display panel. In other words, although this type of ...
