Embodiment 1
[0040] This example will describe in detail the 3D imaging grating assembly disclosed in the present invention, such as Figure 2a , Figure 2b As shown, it discloses a three-dimensional exploded schematic diagram of a 3D display device including a 3D imaging grating assembly and a display panel 2; the 3D imaging grating assembly includes a spectroscopic lens array grating 1 and a collimating lens array grating 3;
[0041] The collimating lens array grating 3 is provided with several collimating lenses 30 distributed in an array;
[0042] The beam-splitting lens array grating 1 includes several beam-splitting lenses 11 arranged in an array;
[0043] Among them, such as image 3 As shown, the width D of the collimating lens is 1 / N of the width of a pixel or sub-pixel (the following will be illustrated in units of pixels) of the display panel 2, and the width H of the dichroic lens 11 is 1 / N of the width of the display panel 2. 2 M times the width of the viewpoint group, wher...
Embodiment 2
[0066] In this example, a 3D display device will be described with reference to the accompanying drawings. like image 3 As shown, including a display panel 2 and a 3D imaging grating assembly;
[0067] The 3D imaging grating assembly is installed in front of the display panel 2 .
[0068] When installing, such as Figure 6-Figure 8 As shown, the 3D imaging grating assembly is installed in front of the display panel 2 by using a transparent medium 4 , that is, one side of the collimator lens array grating 3 is pasted on the display panel 2 . Specifically, the thickness of the transparent medium 4 is related to the width of the pixels on the display panel 2 and the divergence angle θ.
[0069] like Image 6 , Figure 7 As shown, each pixel or sub-pixel on the display panel 2 is a light source, such as an LED light 21 . In the figure, w1 is the thickness of the thinnest part of the collimating lens 30 , and w2 is the distance between the collimating lens 30 and the surface...
