[ example one ]
Referring to fig. 1 to 7, the present embodiment discloses a lens transfer layer 1 and a method for manufacturing the same. In order to facilitate understanding of the structure of the lens transfer layer 1, the method for manufacturing the lens transfer layer will be described, and then the structure of the lens transfer layer 1 will be described, but the lens transfer layer 1 of the present embodiment is not limited to being manufactured according to the manufacturing method. In this embodiment, the method for manufacturing the lens transfer layer includes: a coating step S110, a light shaping step S120, an exposure step S130, and a developing step S140.
The coating step S110: as shown in fig. 1, a negative photoresist layer 12a is coated on a surface of a transparent layer 11. In this embodiment, the light-transmitting layer 11 is made of a transparent material, and the negative photoresist layer 12a may be made of Polyisoprene rubber (Polyisoprene rubber) or Epoxy-based polymer (Epoxy-based polymer), but the invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, the light-transmitting layer 11 may be only light-transmitting but opaque, and the negative photoresist layer 12a may also be made of a negative photoresist material such as thiolene-ethylene (oste) polymer.
The light shape step S120: as shown in fig. 2, a light emitted from a light source 200 passes through a mask 300 to form a predetermined light shape, and further passes through the transparent layer 11 and irradiates the negative photoresist layer 12 a. The light source 200 may be used to emit ultraviolet light, and preferably includes at least one light emitting diode chip capable of emitting light in a range from 340 nanometers (nm) to 410 nm, and the type of the at least one light emitting diode chip includes a laser diode chip, but the type of the at least one light emitting diode chip may be adjusted and varied according to design requirements, which is not limited by the present invention. Furthermore, the mask 300 can be divided into a plurality of portions, and the gray-scale values of each portion of the mask 300 are distributed in a gradient manner.
The exposure step S130: as shown in fig. 2, the light source 200 and the mask 300 are moved relative to the light-transmitting layer 11 so that a portion of the negative photoresist layer 12a adjacent to the plate surface of the light-transmitting layer 11 can be irradiated with the light having the predetermined light shape to form a plurality of lens transfer regions 12. In this embodiment, the thickness of the negative photoresist layer 12a is preferably greater than the thickness of any one of the lens transfer regions 12, and the gray-scale values of the portions of the mask 300 corresponding to any one of the lens transfer regions 12 are distributed in a gradient manner, so that the surface of the lens transfer region 12 can be smooth, thereby facilitating the transfer thereof to form a lens.
In addition, the specific configuration of the plurality of lens transfer areas 12 can be adjusted and varied according to the actual lens design requirements. For example, as shown in fig. 3 and 4, a plurality of the lens transfer regions 12 are disposed at intervals from each other, which can be used to form a plurality of convex lenses or a plurality of concave lenses disposed at intervals; alternatively, as shown in fig. 5, at least some of the lens transfer regions 12 in the plurality of lens transfer regions 12 are connected to each other to form a Fresnel lens (Fresnel lens) transfer region 13, so that a Fresnel lens can be formed.
The developing step S140: as shown in fig. 3 to 5, another portion of the negative photoresist layer 12a where the lens transfer region 12 is not formed is removed, so that the light-transmitting layer 11 and the plurality of lens transfer regions 12 formed on the light-transmitting layer 11 together form a lens transfer layer 1. In this embodiment, a developer corresponding to the negative photoresist layer 12a may be used to dissolve another portion of the negative photoresist layer 12a where the lens transfer region 12 is not formed (i.e., a portion of the negative photoresist layer 12a not irradiated by the light having the predetermined light shape).
The above is the description of the method for manufacturing the lens transfer layer of the present embodiment, and the structure of the lens transfer layer 1 in the present embodiment is described below, but the present invention is not limited thereto. As shown in fig. 3 to 5, the lens transfer layer 1 is a flat plate, preferably a rectangular sheet, and the lens transfer layer 1 includes a transparent layer 11 and a plurality of lens transfer regions 12 formed on the transparent layer 11 by exposing a negative photoresist layer 12a (see fig. 2). Furthermore, a plurality of the lens transfer regions 12 may be disposed at intervals according to design requirements; alternatively, a plurality of lens transfer regions 12 may be connected to each other by at least a portion of the lens transfer regions 12 according to design requirements, so as to jointly form a fresnel lens transfer region 13.
It should be noted that, in the present embodiment, the lens transfer layer 1 includes a bendable form and a non-bendable form, and when the lens transfer layer 1 is in the non-bendable form (for example, fig. 6 and 7), the lens transfer layer 1 can be used to transfer a plurality of lenses L onto a transparent film F through a plurality of lens transfer regions 12. That is, the lens transfer layer 1 and the light-transmitting film F can be directly formed by sheet-to-sheet (sheet-to-sheet) transfer of the plurality of lenses L.
[ example two ]
Referring to fig. 8 to 10, in order to facilitate understanding of the structure of the lens transfer roller 100, the present embodiment discloses a lens transfer roller 100 and a transfer manufacturing method of a lens, and the following will first describe the transfer manufacturing method of the lens and then describe the structure of the lens transfer roller 100.
The transfer-printing type manufacturing method of the lens comprises the following steps: a lens transfer layer forming step, a lens transfer roller forming step S220, and a lens forming step S230. The lens transfer layer forming step and the lens transfer roller forming step S220 are equivalent to the manufacturing process of the lens transfer roller 100, but the lens transfer roller 100 of the present embodiment is not limited to the manufacturing process.
It should be noted that the step of forming the lens transfer layer in this embodiment corresponds to the method of manufacturing the lens transfer layer in the first embodiment; that is, the step of forming the lens transfer layer includes the step of coating S110, the step of light shaping S120, the step of exposing S130, and the step of developing S140, so reference is made to the first embodiment of the step of forming the lens transfer layer, and the step of forming the lens transfer layer will not be described again.
The lens transfer roller forming step S220: as shown in fig. 8 and 9, the transparent layer 11 of the lens transfer layer 1 is attached around the outer surface 21 of a roller 2, so that the lens transfer layer 1 and the roller 2 together form the lens transfer roller 100. In the present embodiment, the lens transfer layer 1 is attached around the outer surface 21 of the roller 2 by a surface (e.g., the bottom surface of the transparent layer 11 in fig. 8) away from the plurality of lens transfer regions 12.
The lens shaping step S230: as shown in fig. 9 and 10, a plurality of lens transfer regions 12 of the lens transfer roller 100 are continuously rolled on a transparent film F to form a plurality of lenses L on the transparent film F. Wherein the number of the plurality of lenses L of the light-transmitting film F is greater than the number of the plurality of lens transfer regions 12 of the lens transfer roller 100. That is, the lens transfer roller 100 and the light-transmitting film F can directly and rapidly transfer and form a plurality of lenses L in a roll-to-roll manner.
The above is a description of the transfer-type manufacturing method of the lens of the present embodiment, and the structure of the lens transfer roller 100 in the present embodiment is described below, but the present invention is not limited thereto. As shown in fig. 8 to 10, the lens transfer roller 100 includes a roller 2 and a lens transfer layer 1 attached to the roller 2. It should be noted that the lens transfer layer 1 in this embodiment is equivalent to that of the first embodiment, so reference is made to the first embodiment for the structure of the lens transfer layer 1, and details of the structure of the lens transfer layer 1 will not be repeated below.
The cross section of the roller 2 is circular, and the roller 2 is preferably a solid structure (e.g., a metal roller) with no light transmission, but the invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, the roller 2 may be a hollow structure according to actual design requirements, and the material of the roller 2 may be adjusted and changed according to the design requirements.
The lens transfer layer 1 is defined as a bendable form in this embodiment, and the lens transfer layer 1 is surrounded and attached to the outer surface 21 of the roller 2 by the transparent layer 11. In the present embodiment, the lens transfer layer 1 is attached around the outer surface 21 of the drum 2 by a surface away from the lens transfer regions 12. In more detail, the lens transfer layer 1 may wrap around the outer surface 21 of the drum 2 by at least 355 degrees, and two edges of the lens transfer layer 1 face each other and leave a gap G exposing the drum 2.
Accordingly, the lens transfer roller 100 can be used to roll and transfer a plurality of lenses L on a transparent film through a plurality of lens transfer regions 12. That is, the lens transfer roller 100 and the light-transmitting film F can directly transfer and form a plurality of lenses L in a roll-to-roll manner. In other words, the structure that does not operate in the rolling transfer manner is different from the lens transfer roller 100 of the present embodiment.
[ technical effects of embodiments of the present invention ]
In summary, the transfer-printing manufacturing method of the lens and the manufacturing method of the lens transfer-printing layer disclosed in the embodiments of the present invention are different from and more efficient than the conventional lens manufacturing method, in that the light beam having the predetermined light shape irradiates the portion of the negative photoresist layer adjacent to the plate surface of the light-transmitting layer to form a plurality of lens transfer-printing areas, so that the production and manufacturing of the lens can be realized by transfer printing.
Furthermore, the lens transfer printing roller and the lens transfer printing layer disclosed by the embodiment of the invention can enable the production and the manufacture of the lens to be realized in a transfer printing mode through the plurality of lens transfer printing areas formed on the light transmitting layer, thereby being different from and more efficient than the existing lens manufacturing method.
The disclosure is only a preferred embodiment of the invention and is not intended to limit the scope of the invention, so that all equivalent technical changes made by using the contents of the specification and drawings are included in the scope of the invention.
