Viewing angle control structure and display device

Abstract

The invention provides a viewing angle control structure and a display device. The display device at least comprises the viewing angle control structure. The viewing angle control structure comprisesa first polarizing layer, a second polarizing layer, a first substrate, a second substrate and a polarization adjusting layer. The first polarizing layer and the second polarizing layer are sequentially arranged on a transmission path of a light beam. The first substrate and the second substrate are sequentially arranged on the transmission path of the light beam and located between the first polarizing layer and the second polarizing layer, and at least one of the first substrate and the second substrate has a birefringence. The polarization adjusting layer is arranged on the transmission path of the light beam and located between the first substrate and the second substrate and used for changing the polarization state of the light beam according to an applied voltage. The viewing angle control structure and the display device are good in peep-proof effect, light, thin and good in image quality.

Description

technical field [0001] The present invention relates to a display device, and in particular to a viewing angle control structure and a display device with an anti-peeping function. Background technique [0002] With the development of technology, display devices have been widely used in daily life of users. In recent years, users have begun to pay attention to privacy issues, hoping to prevent others from peeping important or private information while browsing the screen. At present, some display devices provide anti-peeping function to maintain the privacy of users, but most of the anti-peeping display devices on the market have poor privacy, insufficient screen contrast, or too thick anti-peeping stickers. When applied to thin or flexible display devices, the existing anti-peeping structures are often not accepted by the market because they are too thick or difficult to fit. A privacy-preventing display device that is thin and light and has good display quality. [0003...
