Background

With the increasing popularity of display devices such as computers and mobile phones, many conveniences are brought to the work and life of users, but in some public places with high confidentiality, such as bank teller machines, users do not want to be seen by other people when browsing the display information of the display device, so that the display device needs to be peeped-proof so that the display content cannot be read by other people when observing at a side view angle or a large view angle.

However, in the existing peep-proof technology, the display panel usually has a single display view angle, and a user can only view the display content within a certain angle range, and once the angle exceeds the range, the display content cannot be seen. For example, if a user wants to view some private information in a public place or show some material in a meeting, this single display view can limit the user's use experience and cannot meet the consumer's demand experience in different scenarios.
