Example 1
Fig. 1 is a schematic overall structure diagram of the 3D display system 010 provided in this embodiment, and fig. 2 is a schematic structure diagram of a mask 300 in the 3D display system 010 provided in this embodiment. Referring to fig. 1 and fig. 2 in combination, the present embodiment provides a 3D display system 010, which includes a 2D display panel 200, a lenticular lens 100 and a mask 300. The lenticular lens 100 is disposed in front of the 2D display panel 200, and a distance s between the lenticular lens 100 and the mask 300 is less than a focal length f of the lenticular lens 100. The eye of the viewer passes through the lenticular lens 100 to form a light spot 430 on the mask 300, and the light spot 430 extends in the up-and-down direction. The mask 300 is disposed between the lenticular lens 100 and the 2D display panel 200, or on a side of the 2D display panel 200 away from the lenticular lens 100. Since the mask 300 includes a plurality of depth modulation stripe groups 310 arranged in a first direction (i.e., a direction from top to bottom), the depth modulation stripe groups 310 match the depths of the images displayed on the corresponding 2D display panel 200, and thus the images at different depths are modulated by the mask 300 to generate different visual feelings for the viewer, thereby reducing the asthenopia.
The following further describes the 3D display system 010 provided in this embodiment:
fig. 3 is a schematic structural diagram of the 2D display panel 200 provided in this embodiment. Referring to fig. 3, in the present embodiment, the 2D display panel 200 is formed by a plurality of pixels 211 arranged in an array. On the 2D display panel 200, at least two pixels 211 form a pixel group 210 along the up-down direction, and the depth of the image displayed by the same pixel group 210 is the same. Specifically, in the present embodiment, the 2D display panel 200 is a liquid crystal display panel. At this time, the mask 300 may be disposed between the liquid crystal display panel and the lenticular lens 100, or may be disposed on a side of the liquid crystal display panel away from the lenticular lens 100.
It should be noted that the type of the 2D display panel 200 is not limited herein, and it is understood that in other embodiments, the 2D display panel 200 may be configured as other display panels according to the user's requirement, for example, an OLED (display panel made of organic light emitting diodes), a PDP (plasma display panel), and the like. It should be noted that the mask 300 can only be disposed between the 2D display panel 200 and the lenticular sheet 100 at this time.
Referring to fig. 1, in the present embodiment, in order to obtain a better display effect, a distance between the 2D display panel 200 and the lenticular lens 100 is smaller than a focal length f of the lenticular lens 100. Preferably, the mask 300 is disposed adjacent to the 2D display panel 200. As such, the distance between the mask 300 and the 2D display panel 200 is substantially zero, and the width D of the light spot formed at the 2D display panel 200 by the viewer's eyes is the same as that at the mask 300.
Referring to fig. 2, in the present embodiment, the depth modulation stripe set 310 includes a plurality of first depth modulation stripes 311 and second depth modulation stripes 312 alternately arranged, and the width of the first depth modulation stripes 311 is the same as the width of the second depth modulation stripes 312, so that the image of the same pixel 211 can generate the same visual sensation when passing through the same depth modulation stripe set 310. Meanwhile, the widths of the first depth modulation stripe 311 and the second depth modulation stripe 312 are matched with the depth of the corresponding images, and the images with different depths are modulated by the corresponding depth modulation stripe group 310, so that different visual feelings can be generated. The sum of the widths of the first depth modulation stripe 311 and the second depth modulation stripe 312 is the pitch width l of the depth modulation stripe group 310.
Specifically, the first depth modulation stripe 311 includes a first light-transmitting stripe 313 and a second light-transmitting stripe 314 disposed in a first direction; the second depth modulation stripe 312 includes a second light-transmitting stripe 314 and a first light-transmitting stripe 313 arranged in the first direction; the light transmittance of the first light transmission strip 313 is different from that of the second light transmission strip 314. When the width d of the light spot formed by the viewer's eye at the mask 300 is consistent with the pitch width l of the depth modulation stripe group 310 (as shown in fig. 4), each pixel 211 of the same pixel group 210 can be covered on the light spot 430 at the same ratio, that is, each pixel 211 of the same pixel group 210 can be displayed at the same light intensity, at this time, the image has the strongest high-frequency information, the detail information is fully displayed, and the image texture is clear; when the spot width d is not equal to the pitch width l of the depth modulation stripe group 310 (as shown in fig. 5), at least two pixels 211 of the same pixel group 210 cannot be overlaid on the spot 430 at the same ratio, that is, the pixels 211 of the same pixel group 210 cannot be displayed at the same light intensity, and at this time, high frequency information of the image is weakened and the image texture is blurred. Preferably, the second light-transmitting strip 314 is a light-blocking strip.
Fig. 6 is a schematic diagram of the 3D display system 010 provided in this embodiment. Referring to fig. 6, after passing through the lenticular lens 100, the viewer's eye light is focused to a light spot 430 on the mask 300. When the focal length of human eyes changes, the convergence degree of light rays also changes. When the eyes of the viewers focus on the mask 300 as the first light ray 410 and the second light ray 420 respectively, the spot width d of the spot 430 formed on the mask 300 may also vary due to the difference in the degree of focusing of the light rays. When the width d of the light spot is consistent with the pitch width l of the depth modulation stripe group 310, the corresponding image has the strongest high-frequency information, the detail information is fully displayed, the image texture is clear, and at the moment, the human eyes are focused correctly; when the spot width d is not consistent with the pitch width l of the depth modulation stripe group 310, the high frequency information of the image is weakened, the image texture is blurred, and the human eye is not focused correctly.
The depth modulation stripe groups 310 are arranged in one-to-one correspondence with the pixel groups 210. The pitch of the depth modulation stripe group 310 is set according to the depth of the corresponding image, the depth modulation stripe groups 310 with different pitches are set along the up-down direction, when the focusing of human eyes and the width d of light spots are not changed, because the pitch width l of the depth modulation stripe group 310 is matched with the depth of the corresponding image, the pitch width l of the depth modulation stripe group 310 corresponding to the images with different depths is different, and therefore the definition degrees of the images with different depths when the images with different depths are watched by a viewer are different.
To sum up, the embodiment of the present invention provides a 3D display system 010, which can represent the depth information of the image by the modulation stripes with different pitch widths, and represent the depth of the image by the definition of the image texture when the human eyes focus, so as to reduce the visual fatigue.
The present embodiment also provides a 3D display device (not shown) including the 3D display system 010 described above. Since the 3D display device includes the 3D display system 010, it is also possible to reduce visual fatigue.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
