Display module and convertible peeping preventing displayer

Abstract

The invention relates to a display module which comprises a backlight module and a display module. A light conversion module is further included and comprises a peeping preventing layer and a light conversion layer. The peeping preventing layer and the light conversion layer are arranged between the backlight module and the display module and sequentially arranged in the light emitting direction of the backlight module. The peeping preventing layer comprises a transparent insulation film, a peeping preventing structure and a first transparent conductive film shared by the light conversion layer. The transparent insulation film is attached to the backlight module. The peeping preventing structure is arranged between the transparent insulation film and the first transparent conductive film and fixed to the transparent insulation film and is perpendicular to the backlight module. The light conversion layer comprises a first transparent conductive film, a second transparent conductive film and liquid crystals, and the space between the first transparent conductive film and the second transparent conductive film is filled with the liquid crystals. The display module can be switched between a visible sharing function and a peeping preventing function and is small in thickness. The invention further relates to a convertible peeping preventing displayer.

Description

Technical field [0001] The present invention relates to the technical field of displays, in particular to a display module and a convertible anti-peep display. 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. In the process of using electronic devices, how to protect personal privacy has also become one of the problems that electronic devices need to solve. For example, when a user views and edits important information, there is a potential safety hazard that the information content is peeked, leading to privacy leakage, and when the personal terminal is on public transportation or in other public places, the user does not want the people around to see his mobile phone 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 to achieve th...

Problems solved by technology

The display after using this method has a single anti-peep function. When information sharing is required, the original additional anti-peep layer can only be removed or destroyed, so it cannot well meet the needs of users in different scenarios.
