External 2D/3D switching displaying device

Abstract

The invention discloses an external 2D / 3D switching displaying device which comprises an external glasses-free 2D / 3D mobile phone; an external glasses-free 2D / 3D mobile phone protection film is arranged on the outer side of the external glasses-free 2D / 3D mobile phone; a 2D / 3D switching grating is arranged on one side of the external glasses-free 2D / 3D mobile phone protection film, and is a 2D / 3Dswitching slit grating or a cylindrical lens grating; the 2D / 3D switching grating is of a switchable slit grating structure; a switchable 2D / 3D mobile phone shell sleeves the outer side of the external glasses-free 2D / 3D mobile phone; and a polaroid is arranged on the 2D / 3D switching grating. The external 2D / 3D switching displaying device is simple in structure and convenient to operate, a slit grating device can be adopted to arrange a leading-out structure of a power supply pin and design a final power supply scheme, the 2D / 3D switchable function of an external glasses-free 3D mobile phone shell is realized, the problem that the resolution is reduced when 2D content is watched through the glasses-free 3D mobile phone shell is solved, the use convenience is greatly improved, and the requirements of people are met.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to an external 2D / 3D switching display device. Background technique [0002] Although the external glass-free 3D protective case facilitates the realization of 2D display to 3D display, but because the glass-free 3D is often realized by cylindrical lens or slit grating, the display resolution is greatly reduced without using the 3D function, which seriously affects the customer's experience. Experience; in order not to affect the 2D effect of the mobile phone, it is often necessary to remove the mobile phone film or the case; after removal, the mobile phone film is often easy to absorb dust and other problems and cannot be used again. Taking the mobile phone case back and forth greatly affects the use effect, so it cannot satisfy people's demands. Contents of the invention [0003] The object of the present invention is to propose an external 2D / 3D switching displ...
