Abstract

The invention discloses a display module, a display device and a visual angle control method. The display module comprises a backlight module, a display panel and a lower polaroid, and also comprisesa visual angle switching element and a transparent cover plate; the visual angle switching element and the transparent cover plate are arranged between the display panel and the lower polaroid; the transparent cover plate is arranged on one side, close to the lower polaroid, of the visual angle switching element; the backlight module is used for providing light meeting a preset condition; the visual angle switching element is used for switching the visual angle modes of the display module, the visual angle modes comprise a first visual angle mode and a second visual angle mode, and the visualangle range of the first visual angle mode is less than that of the second visual angle mode. According to the technical scheme provided by the invention, the visual angle switching element used for switching the visual angle of the display module is arranged between the display panel and the transparent cover plate, the relatively large gap is prevented from existing between the visual angle switching element and the lower polaroid, the thickness of the display module can be reduced, and thus the product can be light and thin.

Description

technical field [0001] This article relates to the field of display technology, in particular to a display module, a display device, and a viewing angle control method. Background technique [0002] With the development of society and the enrichment of material conditions, a wide variety of display devices such as mobile phones, computers, and televisions are more and more closely integrated with people's work and life. However, while display devices provide people with many conveniences, privacy leaks are always inevitable. In this regard, some anti-peeping technologies have emerged in the industry. [0003] Relevant anti-peep technologies include: glasses-type technology and naked-eye technology. Among them, glasses-type technology uses external auxiliary devices such as auxiliary glasses to separate and protect confidential information, and naked-eye technology realizes anti-peeping display by controlling the angle of incident light , in the related naked-eye technology...
