Abstract
Description
Technical Field
[0001] The invention relates to a light guide module. Background Art
[0002] Many technological products today have light guide structures installed inside to produce luminous effects. During the lamination and pasting process of the light guide sheets in the light guide structures, positioning lines or positioning holes are often printed on the outer non-functional areas of the light guide sheets for alignment marks, so that the light guide sheets will not produce defects and poor luminous effects due to misalignment during the lamination process. However, these alignment marks will be deleted or coated off after the lamination and pasting of the light guide sheets, resulting in the need for the use of high-precision testing instruments for subsequent product inspections, which makes it impossible to quickly judge the alignment accuracy and production line operators are unable to immediately discover defective products at the first time.

[0064] The preferred embodiments of the present invention are described below with reference to the accompanying drawings.
[0065] See also Figure 1 The exploded perspective view of the first preferred embodiment of the present invention and Figure 2 A perspective exploded view of the first preferred embodiment of the present invention. The light guide module 1 of the present invention comprises a substrate 10, a light guide plate 20, a covering layer 30, a pattern layer 40, a light emitting element L and a bottom layer X. The light guide plate 20 has a plurality of first light guide points 21, a plurality of second light guide points 22, a plurality of third light guide points 23 and a side edge 24. The covering layer 30 has a non-shielding area 31, a shielding area 32 and a spacing area 33. The pattern layer 40 has a character area 41 and an opaque area 42.
[0066] The light guide plate 20 is disposed on the substrate 10, and the covering layer 30 covers the light guide plate 20. The plurality of first light guide points 21 of the light guide plate 20 correspond to the non-shielded area 31 of the covering layer 30, and the plurality of second light guide points 22 of the light guide plate 20 correspond to the shielded area 32 of the covering layer 30. Preferably, the plurality of second light guide points 22 correspond to the edge of the shielded area 32, and the plurality of second light guide points 22 are covered by the shielded area 32, and the plurality of third light guide points 23 correspond to the spacing area 33 of the covering layer 30. The character area 41 of the pattern layer 40 corresponds to the non-shielded area 31 of the covering layer 30, and the opaque area 42 corresponds to the shielded area 32 and the spacing area 33 of the covering layer 30.
[0067] The spacing area 33 of the cover layer 30 is located between the non-shielding area 31 and the shielding area 32, separating the non-shielding area 31 from the shielding area 32. The third light guide points 23 of the light guide layer 20 are arranged between the first light guide points 21 and the second light guide points 22, or between the second light guide points 22, depending on the position of the spacing area 33 of the cover layer 30.
[0068] The light emitting element L is disposed on the side edge 24 of the light guide plate 20 to provide light to enter the light guide plate 20. The bottom layer X is disposed between the substrate 10 and the light guide plate 20. The bottom layer X can be an adhesive layer for bonding the substrate 10 and the light guide plate 20, or the bottom layer X can be a reflective coating for assisting the reflection and transmission of light in the light guide plate 20. The substrate 10 can be a touch circuit board or a bottom plate.
[0069] The covering layer 30 is an adhesive layer or a light shielding coating. When the covering layer 30 is an adhesive layer, it is used to attach the pattern layer 40 to the light guide plate 20. Since the adhesive material used in the adhesive layer is mostly opaque or semi-transparent, light is not easy to penetrate. Therefore, the position covered by the covering layer 30 can be judged by whether the light guide point on the light guide plate 20 is bright or weak. When the covering layer 30 is a light shielding coating, since the light shielding coating is used to shield the light output of the light guide plate 20 to limit the range of light transmission, the position covered by the covering layer 30 can be judged by whether the light guide point on the light guide plate 20 is shielded and does not emit light.
[0070] A plurality of first light guide points 21, a plurality of second light guide points 22 and a plurality of third light guide points 23 are distributed on the entire light guide plate 20. The plurality of first light guide points 21, the plurality of second light guide points 22 and the plurality of third light guide points 23 have different functions and are distributed on the light guide plate 20 with different densities.
[0071] The distribution density of the first light guide points 21 corresponding to the non-shielded area 31 of the cover layer 30 is higher than the distribution density of the second light guide points 22 corresponding to the shielded area 32 of the cover layer 30. The distribution density of the third light guide points 23 is adjusted according to the position of the spacer 33. Depending on the position of the spacer 33, the distribution density of the third light guide points 23 may be higher or lower than the distribution density of the second light guide points 22.
[0072] According to the first preferred embodiment of the present invention, the number of the corresponding multiple first light guide points 21 in the non-shielded area 31 is large and the distribution is dense, that is, the distance between a single first light guide point 21 and the adjacent first light guide point 21 is close. The number of the corresponding multiple second light guide points 22 in the shielded area 32 is small and the distribution is loose, and the distance between a single second light guide point 22 and the adjacent second light guide point 22 is greater than the distance between a single first light guide point 21 and the adjacent first light guide point 21. The number of the multiple third light guide points 23 is less than the multiple second light guide points 22, the distribution density is looser, and the distance between the third light guide points 23 is also larger.
[0073] The multiple first light guide points 21 of the light guide plate 20 are used for light output, so that the light in the light guide plate 20 is emitted through the multiple first light guide points 21. Therefore, the multiple first light guide points 21 are distributed most densely, so that more light can pass through, and because the multiple first light guide points 21 correspond to the non-shielded area 31 of the covering layer 30, the light will not be shielded and can be projected to the character area 41 of the pattern layer 40, making the character area 41 glow.
[0074] The plurality of second light guide points 22 of the light guide plate 20 are used for marking and alignment purposes, and are used to mark and align the positions to be covered by the shielding area 32 of the cover layer 30 on the light guide plate 20, so that the shielding area 32 covers the correct position on the light guide plate 20, and avoids the position deviation or shielding error of the shielding area 32, which leads to poor light emission, and also avoids alignment defects during the lamination process. Since the plurality of second light guide points 22 are shielded by the shielding area 32 under normal conditions, the light emitted by the plurality of second light guide points 22 will not penetrate into the pattern layer 40.
[0075] The plurality of third light guide points 23 of the light guide plate 20 are used for inspection purposes, and are used to simultaneously check and confirm whether both the non-shielded area 31 and the shielded area 32 of the cover layer 30 are correctly aligned and set at the preset position. After the cover layer 30 covers the light guide plate 20, by checking whether the plurality of third light guide points 23 are covered, or whether light points emitted from the plurality of second light guide points 22 appear around the plurality of third light guide points 23, the covering state of the non-shielded area 31 and the shielded area 32 of the cover layer 30 is further confirmed. Furthermore, since the layer spacing area 33 of the cover layer 30 has no shielding effect, the light of the plurality of third light guide points 73 will not be shielded by the cover layer 30, but because the spacing area 33 corresponds to the opaque area 42 of the pattern layer 40, after the pattern layer 40 is set above the cover layer 30, the plurality of third light guide points 73 will still be shielded by the opaque area 42 of the pattern layer 40, and the light of the plurality of third light guide points 23 will not finally pass through the pattern layer 40.
[0076] To further explain the implementation method, the pattern layer 40 will first be designed with a pattern or character that needs to be transparent in the character area 41, and a non-transparent area 42 that does not need to transmit light will be designed. Then, according to the positions of the character area 41 and the non-transparent area 42 of the pattern layer 40, a corresponding cover layer 30 is set to make a non-shielded area 31 and a shielded area 32 of the cover layer 30, so that they correspond to the character area 41 and the non-transparent area 42 of the pattern layer 40. Subsequently, the light guide plate 20 is stacked corresponding to the lower portion of the cover layer 30, and a plurality of first light guide points 21 are set in the area corresponding to the non-shielded area 31 on the light guide plate 20, and a plurality of second light guide points 22 are set in the area corresponding to the shielded area 32, and the third light guide point 23 is set in the interval area 33 between the non-shielded area 31 and the shielded area 32 according to the requirements. Then, the cover layer 30 is covered and attached to the light guide plate 20. Finally, after the test confirms that the first light guide points 21, the second light guide points 22 and the third light guide points 23 are all in the correct corresponding positions, the production of the standard product is completed. Figure 3A shown.
[0077] Continue to read Figure 3A A schematic diagram of the implementation state of the first preferred embodiment of the present invention and Figure 3BA schematic diagram of the implementation status of the first preferred embodiment of the present invention.
[0078] Figure 3A This is an implementation method after the cover layer 30 and the light guide plate 20 are covered and combined under normal circumstances. Figure 3B This is an implementation method in which the cover layer 30 and the light guide plate 20 are covered and combined in the case of positional displacement.
[0079] See also Figure 2 and Figure 3A After the cover layer 30 covers the light guide plate 20, the first light guide points 21 of the light guide plate 20 are exposed in the non-shielded area 31 of the cover layer 30, the second light guide points 22 are shielded by the shielded area 32 and are not exposed, and the third light guide points 23 are exposed in the spacing area 33. After the light emitted by the light emitting element L enters the light guide plate 20, the first light guide points 21, the second light guide points 22 and the third light guide points 23 will all light up, but only the first light guide points 21 and the third light guide points 23 can be detected as bright light, and the second light guide points 22 cannot be detected as bright light because they are shielded, so it can be immediately and easily confirmed that the cover layer 30 is covered and attached to the correct position.
[0080] See also Figure 2 and Figure 3B After the cover layer 30 covers the light guide plate 20, the first light guide points 21 of the light guide plate 20 are exposed in the non-shielded area 31 of the cover layer 30, but due to the error in the covering position, some of the second light guide points 22 are not shielded by the shielded area 32 and are exposed, and the third light guide points 23 are also shielded by the shielded area 32 and are not exposed in the spacing area 33. After the light emitted by the light emitting element L enters the light guide plate 20, the first light guide points 21, the second light guide points 22 and the third light guide points 23 will all light up, but some of the second light guide points 22 are detected to be bright. Figure 3A After comparing the standard product with the standard product, it is determined that there is light at an abnormal position or the position of the light does not conform to the preset position, and the plurality of third light guide points 23 cannot be detected as light because they are covered, so it is determined that the covering layer 30 does not cover the correct position and is a defective product.
[0081] The second preferred embodiment of the present invention is described below. Figure 4 A perspective exploded view of a second preferred embodiment of the present invention, Figure 5 A perspective exploded view of a second preferred embodiment of the present invention, Fig. 6A A schematic diagram of the implementation state of the second preferred embodiment of the present invention and Figure 6B A schematic diagram of the implementation status of the second preferred embodiment of the present invention.
[0082] The light guide module 1 ′ of the touch panel of the second preferred embodiment of the present invention is substantially the same as the light guide module 1 of the first preferred embodiment in terms of component functions, manufacturing methods, and implementation methods. Therefore, the following description will only provide detailed explanations of the differences.
[0083] See first Figure 4 , Figure 5 . A light guide module 1' of a touch panel of the present invention comprises: a substrate 50, a light guide plate 60, a covering layer 70, a pattern layer 80, a light emitting element L' and a bottom layer X'. The light guide plate 60 has a plurality of first light guide point areas 61, a plurality of second light guide point areas 62, a plurality of third light guide points 63 and a side edge 64, the plurality of first light guide point areas 61 have a plurality of first light guide points 611, and the plurality of second light guide point areas 62 have a plurality of second light guide points 621. The covering layer 70 has a plurality of non-shielded areas 71, a plurality of shielded areas 72 and a plurality of spacer areas 73. The pattern layer 80 has a plurality of character areas 81 and an opaque area 82.
[0084] The pattern layer 80 is disposed above the substrate 50, the light guide plate 60 is disposed between the substrate 50 and the pattern layer 80, and the cover layer 70 is disposed between the pattern layer 80 and the light guide plate 60. The light emitting element L' is disposed at the side edge 64 of the light guide plate 60 to provide light to enter the light guide plate 60. The bottom layer X' is disposed between the substrate 50 and the light guide plate 60, and the bottom layer X' can be an adhesive layer or a reflective coating. The cover layer 70 can be an adhesive layer or a light shielding coating. The substrate 50 can be a touch circuit board or a bottom plate.
[0085] The multiple first light guide point areas 61 of the light guide plate 60 correspond to the multiple character areas 81 of the pattern layer 80, and the multiple second light guide points 62 of the light guide plate 60 correspond to the opaque areas 82 of the pattern layer 80. The multiple spacing areas 73 of the cover layer 70 are located between the multiple non-shielding layers 71 and the multiple shielding areas 72, and separate the multiple non-shielding layers 71 from the multiple shielding areas 72, and the multiple spacing areas 73 correspond to the opaque areas 82 of the pattern layer 80. At the same time, the multiple non-shielding areas 71 of the cover layer 70 correspond to the multiple first light guide point areas 61 of the light guide plate 60. The multiple shielding areas 72 correspond to the multiple second light guide point areas 62 of the light guide plate 60, and the multiple second light guide points 621 correspond to the edges of the multiple shielding areas 72 of the cover layer 70. The multiple spacing areas 73 correspond to the multiple third light guide points 63 of the light guide plate 60.
[0086] According to this arrangement, the multiple first light guide point areas 61 of the light guide plate 60 will not be covered or shielded by the multiple non-shielded areas 71 of the cover layer 70, so the multiple first light guide point areas 61 can pass through the multiple character areas 81 of the pattern layer 80, and the multiple first light guide points 611 in the multiple first light guide point areas 61 are exposed, so that the light transmitted from the multiple first light guide points 611 can be emitted to the outside through the multiple character areas 81 of the pattern layer 80, thereby allowing the multiple character areas 81 to produce a luminous effect. The multiple second light guide point areas 62 of the light guide plate 60 are covered and shielded by the multiple shielded areas 72 of the cover layer 70, so the multiple second light guide point areas 62 will not pass through the opaque areas 82 of the pattern layer 80, and the light emitted by the multiple second light guide point areas 62 in the multiple second light guide point areas 62 will also be shielded, and will not be transmitted to the outside. Furthermore, the multiple third light guide points 73 of the light guide plate 60 correspond to the spacing area 73 of the covering layer 70. Since the spacing area 73 has no shielding effect, the light from the multiple third light guide points 73 will not be shielded by the covering layer 70. However, because the spacing area 73 corresponds to the opaque area 82 of the pattern layer 80, when the pattern layer 80 is set above the covering layer 70, the multiple third light guide points 73 will still be shielded by the opaque area 82 of the pattern layer 80, and the light from the multiple third light guide points 73 will not ultimately pass through the pattern layer 80.
[0087] The light emitted by the multiple first light guide point areas 61 of the light guide plate 60 is for producing a luminous effect for the character area 81 of the pattern layer 80, while the multiple second light guide point areas 62 are only for alignment marking purposes. Therefore, the density of the multiple first light guide points 611 distributed in the multiple first light guide point areas 61 will be higher than the density of the multiple second light guide points 621 distributed in the multiple second light guide point areas 62, so that the multiple first light guide points 611 generate more light to display the bright effect of the character area 81.
[0088] Continue to read Fig. 6A A schematic diagram of the implementation state of the second preferred embodiment of the present invention and Figure 6B A schematic diagram of the implementation status of the second preferred embodiment of the present invention.
[0089] Fig. 6A This is an implementation method after the cover layer 70 and the light guide plate 60 are covered and combined under normal circumstances. Figure 6B This is an implementation method in which the cover layer 70 and the light guide plate 60 are covered and combined in the case of positional displacement.
[0090] See also Figure 5 and Fig. 6AAfter the cover layer 70 covers the light guide plate 60, the first light guide points 611 in the first light guide point areas 61 of the light guide plate 60 are exposed in the non-shielded areas 71 of the cover layer 70, the second light guide points 22 in the second light guide point areas 62 are shielded by the shielded areas 72 and are not exposed, and the third light guide points 63 are exposed in the spacing areas 73. After the light emitted by the light emitting element L' enters the light guide plate 60, the first light guide points 71, the second light guide points 72 and the third light guide points 73 will all light up, but only the first light guide points 71 and the third light guide points 73 can be inspected to emit bright light, and the second light guide points 72 cannot be inspected to emit bright light because they are shielded, so it can be immediately and easily confirmed that the cover layer 70 is covered and attached to the correct position.
[0091] See also Figure 5 and Figure 6B After the covering layer 70 covers the light guide plate 60, the multiple first light guide points 611 in the multiple first light guide point areas 61 of the light guide plate 60 are exposed in the multiple non-shielded areas 71 of the covering layer 70, but due to the error in the covering position, the multiple second light guide points 621 originally located in the multiple second light guide point areas 62 are partially exposed without being shielded. Furthermore, the multiple third light guide points 23 are partially shielded by the shielding area 32 and are not exposed in the spacing area 33, or the positions of the multiple third light guide points 23 are offset. After the light emitted by the light-emitting element L' enters the light guide plate 60, the multiple first light guide points 611, the multiple second light guide points 621 and the multiple third light guide points 63 will all light up, but some of the multiple second light guide points 22 will be detected as bright light during inspection, and the light of some third light guide points 63 is not detected or the position of the third light guide points 63 is offset. When comparing Fig. 6A After comparing the standard product, it is determined that there is light at an abnormal position or the position of the light does not conform to the preset position, thereby determining that the covering layer 70 does not cover the correct position and is a defective product.
[0092] The above description is only a preferred embodiment of the present invention. Any other equivalent changes or modifications made without departing from the spirit disclosed in the present invention should be included in the scope of the present invention.
