Description

Technical Field

[0001] The utility model relates to the field of 3D imaging, in particular to an LED imaging prefabricated film and a three-dimensional imaging LED screen. Background Art

[0002] 3D imaging technology is currently used in various front-end digital electronic products. Most of its imaging principles rely on polarization 3D. The most suitable technical field is mainly reflected in the needs of stereoscopic movies. The projector projects completely polarized light waves that are perpendicular to each other. Then, through specific polarized glasses, the audience can see different pictures with their left and right eyes without interfering with each other. Based on this imaging principle, the electromagnetic light equipment used for naked-eye imaging is a part that has never been involved in the existing technology. The naked-eye 3D effect can be designed based on the grating array, but this method is extremely expensive and the operation and maintenance costs are difficult to bear. Ordinary theater projection 3D imaging has many limitations, the space required for imaging is too large, and the imaging effect is far inferior to that of electromagnetic light equipment. Therefore, a prefabricated covering film is designed that can form 3D imaging through electromagnetic equipment, such as LED lights, based on the principle of polarization.

[0003] As an optically soft material, and involving zoned imaging, the requirements for light transmittance are relatively high. In the process of converting electromagnetic optical equipment to 3D, the prefabricated film needs to have a corresponding LED light source. Therefore, an LED light array light source corresponding to the characteristics of the prefabricated film is also a key link in realizing imaging. Utility Model Content

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figure 1 This embodiment provides a LED imaging prefabricated film, including a polarizing stack 100. The polarizing stack 100 is the main part of the prefabricated film and is also the location where polarized light is generated. It is stacked by a first polarizing film 101, a second polarizing film 102, and a first optical adhesive 200. It is obvious that the two polarizing films are formed and combined into the polarizing stack 100 through the bonding characteristics of the first optical adhesive 200, and the first optical adhesive 200 fills the entire polarizing stack 100, including the gaps and pores therebetween, so that the two polarizing films completely form a whole.

[0038] Furthermore, the first polarizing film 101 is provided with a first through hole 101a, and the second polarizing film 102 is provided with a second through hole 102a. The purpose of providing the through holes is to distinguish the polarization positions of the two polarizing films 101 so that the polarization angle can form the required imaging. The first through hole 101a and the second through hole 102a are arranged in an staggered array to form a staggered angle of 90°, thereby meeting the imaging requirements, and the polarization positions are distinguished, which is more conducive to allowing light to be directed to eyes at different angles. The staggered positions also ensure that the polarized light between the films will not overlap at the base point, affecting the imaging effect.

[0039] In general, after the electromagnetic light of the LED screen is emitted through the staggered through holes, it will first pass through a layer of polarizing film to be polarized, and the light at the through holes will directly pass through the polarizing film, and reach the second layer of polarizing film through the optical glue, and be polarized by another layer of film. In this way, two polarized lights affected by different polarizing films are formed and received by the left and right eyes respectively, forming a three-dimensional imaging effect while avoiding the spatial limitations and imaging effect limitations brought about by traditional three-dimensional projection.

[0040] Example 2

[0041] Reference Figure 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and is different from the previous embodiment in that: the first polarizing film 101 and the second polarizing film 102 are bonded together by the first optical adhesive 200 to form a polarizing stack 100, and the first through hole 101a and the second through hole 102a are both provided with the first optical adhesive 200, that is, the bonding range covers all internal components of the polarizing stack 100, including the through holes, and the purpose of filling the through holes is to shorten the bonding distance required for the two polarizing films to form an integral whole. The shorter this distance is, the better the polarization effect and imaging effect of the polarizing stack 100 will be, and the probability of the two polarized lights overlapping will be greatly reduced, including the wider range of scenes applicable to the final prefabricated film.

[0042] Example 3

[0043] Reference Figure 5 , which is the third embodiment of the utility model, and provides a three-dimensional imaging LED screen. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: the first through hole 101a and the second through hole 102a have the same diameter, and the same diameter can ensure that the size of the light beam formed by the polarized light passing through is consistent, that is, the amount of polarized electromagnetic light entering the left and right eyes can be kept consistent as much as possible, and the same through holes further avoid the problem of partial overlap of positions caused by different sizes of polarized light;

[0044] Furthermore, positioning holes 100a are provided on the first polarizing film 101 and the second polarizing film 102. The positioning holes 100a are used to perform preliminary flattening and fixing processing on the polarizing films. With the assistance of the positioning holes 100a, the accuracy of the offset punching can be guaranteed.

[0045] Example 4

[0046] Reference Figure 5 , which is the fourth embodiment of the utility model. This embodiment provides a three-dimensional imaging LED screen. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that the spacing of the positioning holes 100a on the same side is different from the positioning holes 100a on the other side. Such a position relationship of the positioning holes can avoid the first polarizing film 101 and the second polarizing film 102 with misaligned holes, and it is impossible to distinguish the superimposed direction. If the direction is wrong, it will cause the problem of overlapping of the through holes during bonding.

[0047] Example 5

[0048] Reference Figure 5 , which is the fifth embodiment of the utility model. This embodiment provides a three-dimensional imaging LED screen. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that the first polarizing film 101 and the second polarizing film 102 are equal in length, width and height, and the main dimensions of the two films are the same, so that when the first optical glue 200 merges the two, the first optical glue is usually UV optical glue. This optical glue has higher bonding efficiency, and the integrated state of the polarization stack 100 after bonding is more stable. The polarization and radiation of light during light transmission will also be smoother, and the imaging and visual perception will not be affected by size issues.

[0049] Example 6

[0050] Reference Figure 5 , which is the sixth embodiment of the utility model, and this embodiment provides a stereoscopic imaging LED screen. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: the array source 300 is composed of a staggered first light source A and a second light source B; the array source 300 can be understood as a light source board of the LED screen, which is covered with fixed LED light sources, which are divided into the first light source A and the second light source B;

[0051] Furthermore, the first light source A passes through the first through hole 101a, and the second light source B passes through the second through hole 102a. That is to say, the light emitted by the first light source A will not contact the first polarizing film 101, but will pass through the first through hole 101a to reach the second polarizing film 102; while the light emitted by the second light source B will preferentially contact the first polarizing film 101, and when encountering the second polarizing film 102, it will pass through the second through hole 102a without being affected by any polarization. Regardless of whether the first polarizing film 101 is in front or the second polarizing film is in front, the distribution principle of the light source is the same. The first light source A and the second light source B will only be affected by the polarization effect of their respective corresponding polarizing films, and the non-corresponding polarizing films will send the light out through the through holes.

[0052] Example 8

[0053] Reference Figure 5 , which is the eighth embodiment of the utility model, and this embodiment provides a three-dimensional imaging LED screen. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: a second optical glue 400 is provided on one end face of the polarization stack 100, and the second optical glue 400 is bonded to the array source 300. The second optical glue usually adopts OCA optical glue. The high light transmittance of OCA material meets the requirement of making the light source as full as possible through the polarization stack 100. Secondly, the extended bonding characteristics of OCA ensure that no matter what shape and state the light source is, it can be completely and stably covered by the polarization stack 100.

[0054] Example 9

[0055] Reference Figure 5 , which is the ninth embodiment of the utility model, and this embodiment provides a three-dimensional imaging LED screen. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: the first light source A is polarized into the first incident light L by the second polarizing film 102, that is, the light finally received by the human eye by wearing polarized glasses. The first incident light L polarized by the second polarizing film 102 will naturally be received by the lens on one side with the second polarizing film 102, and the second light source is polarized into the second incident light R by the first polarizing film 101, and the second incident light R will naturally be received by the lens on one side of the first polarizing film 101.

[0056] Furthermore, the left and right lenses receive electromagnetic light of different angles and polarization effects to achieve the effect of 3D imaging. This principle is the same as the normal 3D imaging principle, but the formation process and the final presentation effect are far superior to traditional projection 3D imaging.

[0057] Example 10

[0058] Reference Figure 5, which is the tenth embodiment of the utility model. This embodiment provides a three-dimensional imaging LED screen. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: the deviation angle between the first incident light L and the second incident light R is 90°, which can also be understood as the final polarization angle. The layout of the two lights is perpendicular to each other, which actually corresponds to the staggered arrangement of the first through hole 101a and the second through hole 102a. The first incident light L and the second incident light R pass through their respective corresponding lenses and enter the left eye and the right eye of the observer respectively to form 3D imaging.

[0059] In detail, there are many ways to achieve a deviation angle of 90°, for example, the first incident light L points to 45°, the second incident light points to -45°, the first incident light points to 0°, and the second incident light points to 90°. The commonly used deviation methods in the present technical solution are the angle relationship of 0° and 90°.

For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature or number or position of the discrete element may be changed or changed.
