Abstract

The invention relates to a display module which comprises a backlight module, a display panel, a peep preventing layer and a light ray conversion layer. The peep preventing layer and the light ray conversion layer are arranged between the backlight module and the display panel and sequentially arranged in the light emitting direction of the backlight module; the light ray conversion layer has a transparent optical state and a fogging surface optical state; the spreading direction of light rays from the peep preventing layer cannot be changed when the light ray conversion layer is in the transparent state; the light rays from the peep preventing layer can be spread to all the directions when the light ray conversion layer is in the fogging surface state. The display module can be switched between a visual share function and a peep preventing function and can meet the using needs of a user in different scenes. The invention further relates to a display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] With the development of technology, electronic devices such as mobile phones, personal digital assistants and computers have become more and more popular. During the use of electronic devices, how to protect personal privacy has also become one of the problems that electronic devices need to solve. For example, mobile phones, when users view and edit important information, there is a security risk that the content of the information will be peeked, resulting in privacy leaks, and when personal terminals are taking public transportation or in other public places, users do not want people around to see their mobile phones What is displayed on the screen. The traditional way to solve this problem is to add a peep-proof layer on the outer surface of the display of the electronic device, so as to achieve t...
