Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, these implementation details are not necessary in the embodiments of the present invention. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.
Fig. 1A is a flow chart illustrating a method for manufacturing a light guide according to an embodiment of the invention. As shown in fig. 1A, in the present embodiment, the method for manufacturing a light guide includes steps 10, 20, and 30, each of which is described below. In step 10, a film is provided, the film has a first main surface and a second main surface opposite to each other, and the film has at least one light-transmitting film region thereon, where the at least one light-transmitting film region includes at least one light-emitting region and a non-light-emitting region, where the non-light-emitting region surrounds the light-emitting region. In step 20, a die cutting (punch) process is performed on the first major surface of the film material. In step 30, the second main surface of the film is subjected to a die-cutting process, so that the light-transmissive film region on the film is completely separated from the film to form a light-transmissive film. According to another embodiment of the present invention, as shown in fig. 1B, in the present embodiment, the method for manufacturing a light guide further includes a step 40, wherein the step 40 is described as follows. In step 40, a light shielding plate is covered to the non-light-emitting region of the transparent film, and the light-emitting region of the transparent film is exposed. The above steps are described in detail as follows.
Therefore, as the manufacturing method of the embodiment sequentially performs the punching process on the first main surface and the second main surface of the film material, the residual stress generated in the film material can be offset, the amplitude of the warping deformation of the light-transmitting film is reduced, and the flatness of the light-transmitting film is improved. Therefore, the light-transmitting film is not excessively warped and deformed, so that the light-transmitting film is favorably and smoothly attached to a display module.
It should be understood that, in other embodiments, the order of the steps 20 and 30 of the manufacturing method may be interchanged, that is, the first main surface is subjected to the punching process after the light-transmitting film is obtained from the second main surface of the film material.
It should be appreciated that since step 30 is performed by stamping the second major surface of the film material according to the profile of the light-transmissive film region, this step can provide at least two axial (e.g., X-Y) compressive stresses to the second major surface of the film material simultaneously. Therefore, after step 20, regardless of the axial direction of the protrusion of the film material, the manufacturing method of the embodiment can substantially offset the residual stress of the film material caused by the warp deformation in real time, thereby reducing the amplitude of the warp deformation of the light guiding film.
Specifically, in step 10, fig. 2 is a schematic diagram illustrating the operation of step 10 in fig. 1A. As shown in fig. 2, for example and without limitation, the film 100 is a film formed by rolling a material produced by an injection molding and pressing apparatus 200 through a plurality of rollers 210. The step 20 may be directly performed after the film material 100 is formed, however, the invention is not limited thereto, and in other embodiments, the film material 100 may be wound and collected on a roll for subsequent movement to a corresponding processing occasion.
Fig. 3 is a partial perspective view of the region M of fig. 2. As shown in fig. 2 and 3, the film material 100 has a first main surface 101 and a second main surface 102 facing away from each other. The first main surface 101 of the film 100 is pre-formed with a plurality of light-transmissive film regions 130. Each of the light-transmissive film regions 130 includes a light-exiting region 133 and a non-light-exiting region 135, the non-light-exiting region 135 surrounding the light-exiting region 133. For example, the light exiting region 133 of the film material 100 corresponding to each light-transmissive film region 130 is pre-printed with at least one light-guiding dot pattern 134, in other words, the maximum profile formed by the light-guiding dot pattern 134 is the profile of the light exiting region 133, and the region of each light-transmissive film region 130 without the light-guiding dot pattern 134 is the non-light exiting region 135. However, the present invention is not limited thereto, and the light guiding dot pattern may be formed on the transparent film region 130 after step 30.
FIG. 4A is a schematic diagram illustrating the operation of step 20 of FIG. 1A. Fig. 4B is a top view of the film 100 of fig. 3 after step 20. More specifically, in step 20, for example and without limitation, as shown in fig. 4A, the film 100 is placed on a carrier 300 such that at least a portion of the second main surface 102 of the film 100 contacts the processing surface 301 of the carrier 300, the first main surface 101 of the film 100 faces a first knife module 310, and the first knife module 310 includes a first fixing base 311 and a plurality of first knife modules 312. The first cutting dies 312 are fixed on the first fixing base 311, and the first cutting dies 312 are arranged on one surface of the first fixing base 311 facing the carrier 300 at intervals in advance; next, the first insert module 310 vertically punches the first main surface 101 of the film material 100 so as to form a plurality of first processing marks 140 on the first main surface 101 of the film material 100 (fig. 4B). For example, each first processing mark 140 is a linear slit, and the first processing marks 140 are through openings. However, the present invention is not limited to the shape of the first processing mark 140 being a linear slit and whether the first processing mark 140 penetrates the film material 100.
In more detail, the step of vertically punching the first main surface 101 of the film material 100 further includes: moving the first tool module 310 from the first main surface 101 of the film material 100 to the second main surface 102 along a normal direction 302 of the processing surface 301 so as to perform the punching process on the first main surface 101 of the film material 100; alternatively, the film 100 on the carrier 300 is driven along the normal direction 302 of the processing surface 301, so that the first main surface 101 of the film 100 is punched by the first knife modules 310.
The first processing marks 140 are located in the non-light-exiting region 135 of each light-transmissive film region 130 (fig. 4B), and the first processing marks 140 located in each non-light-exiting region 135 are arranged at intervals along the edge of the light-transmissive film region 130. The first cutting dies 312 arranged on the first fixing base 311 at intervals in advance can make the first processing marks 140 punched by the first cutting dies 312 on the first main surface 101 be located in the non-light-exiting region 135 of each light-transmitting film region 130 at intervals.
More specifically, each of the light-transmissive film regions 130 is substantially rectangular, and each of the light-transmissive film regions 130 defines two long edges 131 and two short edges 132, each of the long edges 131 is adjacent to and between the two short edges 132, and each of the short edges 132 is adjacent to and between the two long edges 131. 3 of the first processing marks 140 (fig. 4B) in each non-light-exiting region 135 are arranged along one of the long edges 131 of the light-transmissive film region 130, that is, the first processing marks 140 are linearly arranged at intervals and are substantially parallel to the long edges 131; 2 of the first machining marks 140 (fig. 4B) are arranged along one of the short edges 132, that is, the first machining marks 140 are linearly arranged at intervals and are substantially parallel to the short edge 132.
In addition, referring back to fig. 4A and 4B, the first cutting module 310 further includes a plurality of third cutting dies 313. The third cutting die 313 is fixed on the first fixing base 311 (fig. 4A), and is pre-arranged on a surface of the first fixing base 311 facing the carrier 300. In this way, when the third cutting die 313 vertically cuts the first main surface 101 of the film material 100, the first main surface 101 of the film material 100 can be formed with the plurality of second processing marks 150 (fig. 4B). The second processing traces 150 are not arranged along the edge of the transparent film region 130, but are located near the light-emitting region 133 and between the light-emitting region 133 and the periphery defined by the first processing traces 140.
Since the film material 100 is in a thin film shape, the film material 100 may have an appearance such as bending or warping due to an excessively small thickness or environmental variables such as field temperature or humidity, in other words, the film material 100 may have a wavy shape, that is, the film material 100 has the protrusions 110 and the recesses 120 spaced apart from each other, each protrusion 110 has a long strip shape, and each protrusion 110 is located between any two adjacent recesses 120. In step 20, the raised portions 110 of the first main surface 101 of the film material 100 may be punched. Specifically, the third cutting dies 313 are aligned with a part of the raised parts 110, respectively, so as to vertically cut the first main surface 101 of the film 100 from the raised parts 110. Preferably, the third cutting dies 313 are respectively aligned with the highest points 111 of the raised portions 110, so as to vertically cut the first main surface 101 of the film material 100 from the highest points 111 of the raised portions 110.
FIG. 5 is a schematic diagram illustrating the operation of step 30 of FIG. 1A. In step 30, the film material 100 is first inverted by 180 degrees, and the film material 100 is placed on the stage 300. As shown in fig. 5, the first main surface 101 of the film 100 faces the processing surface 301 of the stage 300, and the second main surface 102 of the film 100 faces a second knife module 320. The second cutting module 320 includes a second fixing base 321 and a second cutting die 322. The second cutting die 322 is fixed on the second fixing base 321, the second cutting die 322 is preset on a surface of the second fixing base 321 facing the carrier 300, and a blade profile of the second cutting die 322 is the same as an outline of each light-transmissive film region 130. Next, the second cutting die 322 vertically cuts the second main surface 102 of the film material 100 so that the light transmissive film region 130 can be completely separated from the film material 100. Thus, the light-transmitting film region 130 completely separated from the film 100 becomes the light-transmitting film 160, and the non-light-emitting regions 135 and the light-emitting regions 133 of the light-transmitting film region 130 become the non-light-emitting regions 135 and the light-emitting regions 133 of the light-transmitting film 160.
More specifically, the step of vertically punching the second main surface 102 of the film material 100 further includes moving the second blade block 320 from the second main surface 102 of the film material 100 toward the first main surface 101 along the normal direction 302 of the processing surface 301 so as to perform the punching process on the second main surface 102 of the film material 100; alternatively, the film material 100 on the carrier 300 is driven along the normal direction 302 of the processing surface 301, so that the second main surface 102 of the film material 100 is punched by the second knife modules 320.
In addition, although the first machining traces 140 and the second machining traces 150 are formed by punching with a cutting die in the above embodiments, the invention is not limited thereto, and in other embodiments, the first machining traces 140 and the second machining traces 150 may be formed by etching, hardware, laser, CNC machining or laser machining.
FIG. 6 is a schematic diagram illustrating the operation of step 40 of FIG. 1B. FIG. 7 is a top view of a light guide 400 according to an embodiment of the invention. In step 40, more specifically, a light shielding sheet 500 is attached to one surface 161 of the light transmissive film 160, the light shielding sheet 500 has an exposure opening 510, in this embodiment, the light shielding sheet 500 is a transparent sheet (such as a polyester film, but the invention is not limited thereto), and a light shielding pattern is printed or coated on the light shielding sheet 500 except for the exposure opening 510. The light shielding sheet 500 is used to cover the non-light-exiting region 135 of the light-transmitting film 160, the first processing marks 140 and the second processing marks 150, and the exposure opening 510 of the light shielding sheet 500 exposes the light-exiting region 133 of the light-transmitting film 160 and the light-guiding dot pattern 134.
FIG. 7 is a top view of a light guide 400 according to an embodiment of the invention. Fig. 8 shows a cross-sectional view along line AA of fig. 7. As shown in fig. 7 and 8, the light guide 400 includes a light transmissive film 410, a light emergent pattern 440, a plurality of first processing traces 452, a plurality of second processing traces 453, and a light shielding sheet 500. The light-transmissive film 410 has a plurality of light-exiting regions 420 and a non-light-exiting region 430. The non-light exiting region 430 surrounds the light exiting region 420. The light exit pattern 440 includes a plurality of light guide dot patterns 451. The light guide dot patterns 451 are respectively located in the light emitting areas 420 one by one, and the light guide dot patterns 451 are arranged in the light emitting areas 420 according to an array manner. The first processing mark 452 and the second processing mark 453 are located in the non-light-exiting region 430 of the light-transmissive film 410. The light shielding sheet 500 covers the non-light-exiting region 430, the first processing traces 452, and the second processing trace 453 of the light-transmitting film 410. The light shielding sheet 500 has a plurality of exposure openings 510. The exposure openings 510 expose the light guide dot patterns 451, respectively.
More specifically, the light transmissive film 410 includes a first film side 411 and a second film side 412 that face away from each other. For example, but not limited to, the first film surface 411 is substantially rectangular and has two opposite long sides 411L and two opposite short sides 411S, each long side 411L is adjacent to and between the two short sides 411S, and each short side 411S is adjacent to and between the two long sides 411L. Thus, the light guide dot patterns 451, the first processing marks 452, the second processing marks 453, and the light shielding sheet 500 are all located on the first film surface 411 of the light transmissive film 410, and the light shielding sheet 500 covers the first film surface 411, the first processing marks 452, and the second processing marks 453 of the light transmissive film 410.
The light emitting pattern 440 includes a plurality of pattern columns 450. The pattern rows 450 are parallel to each other, and a gap G is formed between any two pattern rows 450. Each pattern row 450 is substantially parallel to the long axis direction L of the first film surface 411. Each pattern column 450 contains a portion of light directing dot pattern 451. The light guide dot patterns 451 of each pattern row 450 are arranged at intervals in a single row, however, the present invention is not limited thereto.
The first processing marks 452 are arranged at intervals along the edge of the light-transmissive film 410, and more specifically, a part of the first processing marks 452 is arranged at intervals along the long sides 411L of the first film surface 411 of the light-transmissive film 410, and another part of the first processing marks 452 is arranged at intervals along the short sides 411S of the first film surface 411 of the light-transmissive film 410. Each of the second processing traces 453 is located in the space G between two adjacent pattern rows 450. For example, each of the first processing mark 452 and the second processing mark 453 is a straight slit, however, the shape of the first processing mark 452 and the second processing mark 453 is not limited in the present invention.
In addition, the light-transmitting film 410 further has a plurality of slots 454. Each slot 454 is formed in the first side 411 for receiving at least one light source (e.g., a light emitting diode, not shown). For example, each slot 454 is between the two short sides 411S of the first film side 411.
As shown in fig. 8, each or at least one of the first processing marks 452 is a through opening, that is, the first processing mark 452 connects the first film surface 411 and the second film surface 412 of the light-transmitting film 410.
