FIG. 3 is a partially enlarged schematic view showing a 3D display layer of another embodiment of the present invention. Please refer to Figure 1, Figure 2 and Figure 3. 1 shows a 3D display layer 10. The 3D optical structure B2 of the 3D display layer 10 is, for example, a naked-lens 3D Lenticular Lens structure, an Lens array or a Fly eye structure. . This embodiment does not limit the aspect of the 3D optical configuration B2.

2 is a schematic view of the 3D display layer 10 of the A-A section of FIG. In detail, the 3D display layer 10 of FIG. 2 includes a base structure B1 and a 3D optical structure B2. In practice, the base structure B1 has a first side 101 and a second side 102. The second surface 102 is used to connect a light transmissive layer (not shown). The 3D optical structure B2 is formed on the first surface 101 of the base structure B1. The 3D optical structure B2 includes a plurality of cylindrical lenses 103. The top T of each of the cylindrical lenses 103 protrudes toward a first direction D1, and each of the lenticular lenses 103 has a curved surface C1.

The base structure B1 has a thickness h1, and the base structure B1 is, for example, a polyethylene terephthalate (PET). This embodiment is not limited The aspect of the base structure B1 is made. For convenience of description, the first direction D1 of the embodiment is illustrated by a direction perpendicular to a display surface (not shown) of the display module (not shown), and the second direction D2 is approximately the first The direction D1 is vertically staggered to illustrate. This embodiment does not limit the aspect of the first direction D1 and the second direction D2.

Further, the curved surface C1 of each of the lenticular lenses 103 has a discontinuous arc structure surface area A1 and two smooth arc surface areas A2, A3. In practice, the discontinuous arc structure surface area A1 is disposed at the top T of each of the lenticular lenses 103, and the discontinuous arc structure surface area A1 is, for example, a sawtooth structure curved surface, a rough structural curved surface, an irregular structural curved surface, or a smooth surface. The two smooth curved surface areas A2 and A3 are respectively disposed on both side portions of each of the lenticular lenses 103. Briefly, the discontinuous arc structure area A1 is located between the two smooth arc areas A2, A3. The arc length of the discontinuous arc structure surface area A1 is projected to the width P2 of the first surface 101 is less than or equal to two-thirds of the width P1 (Lens Pitch) of the single lenticular lens 103.

Further, the discontinuous arc structure surface area A1 is used to scatter or refract the light beam outputted by the RGB pixels of the display module, so that the light beam output by the RGB pixel can diffuse the focus range to the eye of the viewer. Achieve the average distribution of light energy and reduce the phenomenon of moiré caused by 3D display. Conversely, the smooth arcuate areas A2 and A3 are used to focus the light beams output by the RGB pixels of the display module, so that the light beams output by the RGB pixels can be respectively focused to the left or right eye of the viewer. The efficacy of 3D display.

When the width P2 of the discontinuous arc structure surface area A1 projected to the first surface 101 is greater than two-thirds of the width P1 of the single lenticular lens 103, the display effect of the 2D at this time will be greater than the display effect of the 3D, so that the viewer cannot Clearly viewing the 3D image, so the projection of the discontinuous arc structure area A1 to the width P2 of the first side 101 needs to be less than or equal to Two-thirds of the width of the single cylindrical lens 103 is P1.

Generally, the curved surface of the lenticular lens or the curved surface at the top is a smooth curved surface, so that the light beams output by the RGB pixels can be respectively focused to the left and right eyes of the viewer, thereby allowing the viewer to view the 3D. Display images. However, too much or too little beam focusing will cause the viewer to view a 3D display image with significant moiré. Therefore, in this embodiment, the curved surface of the top portion T of each of the lenticular lenses 103 is designed as a discontinuous arc structure surface area A1, whereby the diffused light beam is focused to the range of the viewer's eyes, so that the light energy projected to the eyes can be more Evenly distributed.

In other words, the curved surface of the top portion T of each of the lenticular lenses 103 is, for example, a curved surface of a 2D display image. The curved surfaces of the both side portions of each of the lenticular lenses 103 are, for example, curved surfaces of 3D display images. Therefore, in this embodiment, the optical design of the smooth arc surface areas A2 and A3 of the discontinuous arc structure area A1 and the 3D display image of the lenticular lens 103 through the lenticular lens 103 is achieved, so as to reduce the smear interference phenomenon of the 3D display. And achieve a good 3D display.

Of course, the ratio of the discontinuous arc structure surface area A1 and the smooth arc surface area A2, A3 occupying the entire curved surface C1 of each of the lenticular lenses 103 is adjustable. This embodiment is explained by "the projection of the arc length of the discontinuous arc structure surface area A1 to the width P2 of the first surface 101 is less than or equal to two-thirds of the width P1 of the single lenticular lens 103". Wherein, if the arc length of the discontinuous arc structure surface area A1 is projected to the width P2 of the first surface 101 exceeds two-thirds of the width P1 of the single cylindrical lens 103, the 3D display layer 10 may reduce the effect of the 3D display image. .

In other embodiments, the arc length of the discontinuous arc structure surface area A1 is projected to the width P2 of the first surface 101 may be less than or equal to one-half, one-third, four-minutes of the width P1 of the single lenticular lens 103. One or other value. This embodiment does not limit "discontinuity" The arc length of the arc structure surface area A1 is projected to the width P2 of the first surface 101 to occupy the ratio of the width P1 of the single lenticular lens 103".

It is worth mentioning that "the arc length of the discontinuous arc structure area A1 is projected to the width P2 of the first surface 101 is less than or equal to two-thirds of the width P1 of the single lenticular lens 103", which is substantially similar to "discontinuity". The arc length of the arc structure surface area A1 occupies less than or equal to one-half of the total curved surface C1 of each of the lenticular lenses 103. That is to say, the arc length of the discontinuous arc structure surface area A1 occupies less than or equal to one-half of the total curved surface C1 of each of the lenticular lenses 103, thereby reducing the hysteresis interference phenomenon of the 3D display and achieving good 3D. display effect.

Wherein, if the discontinuous arc structure surface area A1 occupies more than one-half of the total curved surface C1 of each of the lenticular lenses 103, the 3D display layer 10 may reduce the efficiency of the 3D display image. According to the prior art, the person skilled in the art can freely design "the ratio of the discontinuous arc structure surface area A1 and the smooth arc surface area A2, A3 occupying the entire curved surface C1 of each of the lenticular lenses 103, respectively".

4 is a schematic view of a lenticular lens of a 3D display layer of another embodiment of the present invention. Please refer to Figure 4 and Figure 3. The 3D display layers 10a, 10 in FIG. 4 and FIG. 3 have similar 3D display images and the effect of reducing the 3D display moiré interference phenomenon. However, the difference between the 3D display layers 10a, 10 in FIGS. 4 and 3 is that each of the lenticular lenses 103 of the 3D display layer 10a has a smooth surface A5.

In detail, a 3D display layer 10a is configured to form a 3D display structure with a light transmissive layer (not shown), and the 3D display structure is disposed on a display module having a display surface. The 3D display layer 10a includes a base structure B1 and a 3D optical structure B2. Wherein, the 3D optical structure B2 is formed on the first side 101 of the base structure B1, and the 3D light The learning structure B2 includes a plurality of lenticular lenses 103, and the top portion T of each of the lenticular lenses 103 protrudes toward a first direction D1. Each of the lenticular lenses 103 includes a smooth surface A5 and two smooth curved surface areas A2, A3. The two smooth curved surface areas A2 and A3 are respectively disposed on both sides of each of the lenticular lenses 103, and the smooth curved surface areas A2 and A3 are formed according to a preset midpoint (that is, a midpoint of the arc length) to form a curved curved surface. As shown in Figure 4.

In other words, in the present embodiment, the technique of "deleting the focus function of the top portion T of each of the lenticular lenses 103" is employed, so that the top portion T of each of the lenticular lenses 103 forms a smooth surface A5. Of course, the light beam outputted by the RGB pixels of the display module refracts the light beam through the smooth surface A5, so that the light beam output by the RGB pixel can be diffused and focused to the eyes of the viewer, thereby achieving the phenomenon of reducing the aliasing of the 3D display. Conversely, the smooth arcuate areas A2 and A3 are used to focus the light beams output by the RGB pixels of the display module, so that the light beams output by the RGB pixels can be respectively focused to the left and right eyes of the viewer. The efficacy of 3D display.

Similarly, the ratio of the smooth surface A5 and the smooth curved surface areas A2 and A3 occupying the projection width of each of the lenticular lenses 103 can be adjusted. In the present embodiment, "the width P2 projected onto the first surface 101 by the smooth surface A5 is less than or equal to two-thirds of the width P1 of the single lenticular lens 103". That is, the width of the smooth curved surface areas A2, A3 projected to the first surface 101 is greater than or equal to one third of the width P1 of the single cylindrical lens 103. Wherein, if the smooth surface A5 is projected to the width P2 of the first surface 101 by more than two-thirds of the width P1 of the single lenticular lens 103, the 3D display layer 10 may reduce the efficiency of the 3D display image.

In other embodiments, the width P2 projected by the smooth surface A5 to the first surface 101 may be less than or equal to one-half, one-third, one-quarter, or other values of the width P1 of the single lenticular lens 103. This embodiment does not limit "the smooth surface A5 is projected to the first side. The width P2 of 101 occupies the ratio of the width P1 of the single lenticular lens 103".

It is worth mentioning that the shortest distance between the first end T1 of the lenticular lens 103 and the first surface 101 is a first height ht1, and the shortest between the second end T2 of each lenticular lens 103 and the first surface 101 The distance is a second height ht2, and the first height ht1 is equal to or not equal to the second height ht2. For convenience of explanation, the first height ht1 of the embodiment is equal to the second height ht2 for explanation. In other embodiments, the first height ht1 can be less than or greater than the second height ht2. That is, the smooth surface A5 is not parallel to the first surface 101, or the smooth surface A5 is inclined at an angle with respect to the second direction D2, and extends from the first end T1 to the second end T2.

In summary, the present invention utilizes a 3D display layer to optically design a discontinuous arc structure surface region (ie, a zigzag structure curved surface, an irregular structure curved surface, or a smooth surface) through each lenticular lens. The group can reduce the aliasing interference of the output of a 3D image through the 3D display structure, and the viewer can view the better quality 3D image with the naked viewer. Moreover, the light beam outputted by the display module passes through the discontinuous arc structure surface area, and the light beam will generate a state of scattered light or refracted light, so that the viewer can view the 3D image with reduced or no moiré. It is worth mentioning that the width of the projection of the discontinuous arc structure into the first surface occupies the ratio of the width of each single cylindrical lens, or The portion of the top of each lenticular lens that removes the focus function "occupies a ratio of the width of each of the individual lenticular lenses to reduce the 3D image of the 3D display layer and achieve a good 3D visual effect.
