Detailed Description
A specific embodiment of a 3D display device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
The thicknesses of the layers and the size and shape of the regions in the drawings do not reflect the true scale of a 3D display device and are only intended to illustrate the present invention.
As shown in fig. 1, a 3D display device provided in an embodiment of the present invention includes: a non-polarized display 3, a first liquid crystal lens 1 disposed on the non-polarized display 3, and a second liquid crystal lens 2 disposed on the first liquid crystal lens 1; wherein,
the first liquid crystal lens 1 is provided with a plurality of lens units (one lens unit is schematically shown in a semicircle in fig. 1), and each lens unit in the first liquid crystal lens 1 only has a converging effect on a component in a first direction of a polarization direction in light rays emitted by the non-polarization display 3 in a 3D display mode, namely the first liquid crystal lens 1 does not have an effect on components in other directions of the light rays;
the second liquid crystal lens 2 is provided with a plurality of lens units, and in a 3D display mode, each lens unit in the second liquid crystal lens 2 only has a converging effect on a component of a light ray emitted by the non-polarized display 3, wherein the component of the polarization direction of the light ray is along a second direction, namely the second liquid crystal lens 2 does not have an effect on components of the light ray in other directions;
the lens units in the second liquid crystal lens 2 correspond to the lens units in the first liquid crystal lens 1 one by one; the second direction is orthogonal to the first direction.
Specifically, the non-polarized display is a display capable of converting electric energy into light energy and automatically emitting light, such as an OLED, a PDP, or a CRT.
According to the 3D display device provided by the embodiment of the invention, the unpolarized light emitted by the active light-emitting display 3 is divided into polarized light in two orthogonal directions through the two overlapped liquid crystal lenses, namely the first liquid crystal lens 1 and the second liquid crystal lens 2, compared with the method that the unpolarized light is directly converted into the polarized light and then the polarized light passes through the light barrier to realize 3D display, the loss of light energy can be reduced, the display brightness of the whole 3D display is greatly enhanced, and thus the energy consumption required by display is reduced.
By way of example, for example: setting the first direction as the x direction, setting the second direction as the y direction, wherein the dotted line in fig. 1 is polarized light in the x direction, and the solid line is polarized light in the y direction, the first liquid crystal lens 1 plays a role in converging the polarized light in the x direction, that is, the polarized light in the x direction after passing through the first liquid crystal lens 1 is converged at the focal point of the lens unit of the first liquid crystal lens 1, while the polarized light in the y direction is not affected, for example, the left eye diagram emits parallel light rays after passing through the liquid crystal lens 1, and converges in the left eye viewing area to enter the left eye of a human; the second liquid crystal lens 2 has a function of converging the polarized light in the y direction, that is, the polarized light in the y direction after passing through the second liquid crystal lens 2 is converged at the focus of the lens unit of the second liquid crystal lens 2, while the polarized light in the x direction is not affected; after passing through the two layers of liquid crystal lenses, the unpolarized light is split into x-direction and y-direction polarized light with orthogonal directions to realize 3D display.
In practical implementation, the distance between the first liquid crystal lens 1 and the second liquid crystal lens 2 and the thickness thereof should be minimized to avoid that the difference between the heights of the two is too large, which causes the difference between the focal lengths of the two to be too large, and causes the viewing field width of the viewer to be too large. Preferably, in the 3D display mode, a difference between a focal length of each lens unit in the first liquid crystal lens and a focal length of each pixel unit in the second liquid crystal lens is not greater than 2 mm.
Generally, a pixel unit in a display is composed of three sub-pixels, for example, three sub-pixel units of red, green and blue, and in the 3D display mode, a picture seen by the left eye can be displayed on odd sub-pixel columns, and a picture seen by the right eye can be displayed on even sub-pixel columns; of course, the frames seen by the left eye and the right eye may be displayed at intervals in a period of n sub-pixel columns, which is not limited herein.
In this way, due to the corresponding arrangement of the lens units in the first liquid crystal lens 1 and the second liquid crystal lens 2, one lens unit in the first liquid crystal lens 1 and the second liquid crystal lens 2 can correspond to two adjacent columns of sub-pixel units in the non-polarized display 3, wherein one column of sub-pixel units displays a left eye diagram, and the other column of sub-pixel units displays a right eye diagram, for example, the Ni-th lens unit in the first liquid crystal lens 1 and the Mi-th lens unit in the second liquid crystal lens 2 both correspond to the i-th group of sub-pixel units of the display, so that the pictures seen by the left eye and the right eye can be separated, and 3D display can be realized.
The first liquid crystal lens 1 and the second liquid crystal lens 2 in the 3D display device provided by the embodiment of the present invention may have multiple structures, and the specific structures of the first liquid crystal lens 1 and the second liquid crystal lens may be the same or different, wherein the initial orientation of the liquid crystal in the first liquid crystal lens 1 and the initial orientation of the liquid crystal in the liquid crystal lens 2 need to be orthogonal, so as to achieve an effect that the two liquid crystal lenses respectively play a role in converging incident light along components in different directions.
