Embodiment 1

[0044] Please also refer to figure 1 The mobile phone cover provided by the first embodiment of the present invention includes a display cover body 11, the display cover body is provided with a cavity for accommodating the mobile phone, and the shape of its inner surface is adapted to the shell of the mobile phone, at least with the front view surface or rear surface of the mobile phone. The display portion 12 of the display cover body corresponding to the viewing surface is made of high light-transmitting material, and the display portion 12 of the display cover body is figure 1 In the dotted line area, the inner side of the display part is a microlens array. The display part 12 of the display cover body refers to the part opposite to the screen when the front is set on the mobile phone. The display part 12 of the display cover body must be made of high light-transmitting material. When it is placed on the front of the mobile phone, the display part 12 of the display cover b...

Embodiment 2

[0055] like image 3 As shown, the display cover body provided by the second embodiment of the present invention is detachably connected to the mobile phone by wrapping the four sides.

[0056] Further, two first vacancies 131, 132 are set on the front view of the display cover body, and the position and shape of the first vacancy correspond to the position and shape of the rear camera and front camera of the mobile phone and the home case. , and when multiple first vacancies 131 and 132 overlap, they can be merged into one vacancy. The setting of the first vacancy has taken into account the two situations of being covered in the front and being covered in the reverse side.

[0057] Further, three second vacant spaces 141, 142, 143 are set on the four side views of the display cover body, and the positions and shapes of the second vacant spaces 141, 142, 143 are similar to those of the volume buttons, power on and off of the mobile phone. The positions and shapes of the butt...

Embodiment 3

[0061] Figure 4 It shows the implementation process of the 3D display method provided by the third embodiment of the present invention. This method is applicable to the 2D display device covered with the 3D display cover described in the first and second embodiments. The 2D display device includes but not limited to mobile phones, tablet, ipad. The mobile phone is taken as an example for illustration, and the details are as follows:

[0062] In step S401, the position of the human eye is acquired through the front camera of the mobile phone, and the display angle corresponding to the position of the human eye is calculated.

[0063] In this embodiment, open the 3D playback APP on the mobile phone with the 3D display cover, the APP obtains the current position of the human eye through the front camera of the mobile phone, and calculates the display angle corresponding to the position of the human eye. The specific steps are as follows:

[0064] Sub-step S11, divide the human...

Abstract

The invention is applicable to the technical field of 3D display and provides a 3D display sleeve, a 3D display method and a 3D display device. The invention aims to solve a problem that the compatibility of 2D and 3D display can not be realized by an existing display product. The 3D display sleeve comprises a display sleeve body which is provided with a cavity for receiving a 2D display device, the shape of the inner surface of the cavity is adapted to the shell of the 2D display device, the display part of the display sleeve body which is at least corresponding to the front surface or back surface of the 2D display device is made of a high transparent material, and the inner side of the display part is a micro lens array. The 3D display sleeve sleeves the front surface of the 2D display device to cover a screen, a naked eye 3D function can be achieved, the space above the 2D display device is subjected to symmetric design and comprises the spaces of an exposed camera, a home key, a headset hole, volume keys, an ON/OFF key and the like, and when the 3D display sleeve sleeves the back side of the 2D display device, the 3D display sleeve can be used a common mobile phone sleeve and has a protection function.

Description

technical field [0001] The invention belongs to the technical field of 3D display, and in particular relates to a 3D display cover, a display method and a display device. Background technique [0002] In recent years, with the continuous maturity of 3D technology, the 3D display industry has developed rapidly, and various 3D display products have been introduced to the market, such as glasses-free 3D mobile phones, glasses-free 3D tablet computers, glasses-free 3D monitors, glasses-free 3D TVs, glasses-free 3D advertising machines, etc. Wait. At present, the mainstream technologies of naked-eye 3D mainly include the following types, liquid crystal switchable slit grating, reflective fixed slit grating, lenticular lens optical film, prismatic lens optical film, liquid crystal lenticular lens, etc. Its ubiquitous cost is high, the cycle is long, promotion is difficult, and additional design needs to be added in the product design stage, and once customized, it is irreversible...
