In this embodiment, the light-emitting element is, for example, but not limited to, a CSP LED. The CSP LED is a chip-level packaged LED device, which has a small size, which is advantageous for disposing in a crowded space in the touch module.

The light guide plate 40 is arranged between the first light-emitting element 21 and the second light-emitting element 22. The light reflecting plate 50 is disposed above the light guide plate 40. In this embodiment, the first light-emitting element 21 and the second light-emitting element 22 respectively have a first upper light-emitting surface 211 and a second upper light-emitting surface 222. In other words, the first upper light-emitting surface 211 and the second upper light-emitting surface 222 are the surfaces of the first light-emitting element 21 and the second light-emitting element 22 facing the reflector 50.

The reflector 50 is made of a transparent and light-transmitting material, such as but not limited to polyethylene terephthalate. The first surface 51 of the light reflecting plate 50 is provided with a light transmitting area 511, a light shielding area 512, a first light reflecting area 513 and a second light reflecting area 514. The light-transmitting area 511 can allow light generated by the first light-emitting element 21 and the second light-emitting element 22 to pass through. The light-shielding area 512 blocks the light generated by the first light-emitting element 21 and the second light-emitting element 22 from penetrating. The light-shielding area 512 is, for example, printed by a light-shielding ink layer. The first light reflecting area 513 and the second light reflecting area 514 reflect the light generated by the first light emitting element 21 and the second light emitting element 22 back to the light guide plate 40. The first reflective area 513 and the second reflective area 514 are, for example, printed with a white ink layer. Specifically, a black light-shielding ink layer is first printed on the first surface 51 of the reflector 50 to form a light-shielding area 512, leaving a partially transparent light-transmitting area 511, and then a white light-shielding ink layer is printed on part of the black light-shielding ink layer , Forming a first reflective area 513 and a second reflective area 514.

第一反光區513與第二反光區514分別對應第一發光元件21與第二發光元件22設置。所述第一反光區513之涵蓋範圍大致為第一發光元件21至透光區511之間的路徑。所述第二反光區514之涵蓋範圍大致為第二發光元件22至透光區511之間的路徑。The first light reflecting area 513 and the second light reflecting area 514 are respectively disposed corresponding to the first light emitting element 21 and the second light emitting element 22.

The coverage area of the second light-reflecting area 514 is roughly the path from the second light-emitting element 22 to the light-transmitting area 511.

再次參閱圖1，所述遮光區512的面積大於透光區511的面積但不以此為限。遮光區512的面積大於第一反光區513或第二反光區514的面積。第一反光區513與第二反光區514的面積分別大於第一上方出光面211與第二上方出光面222的面積。Referring to FIG. 1 again, the area of the light-shielding area 512 is larger than the area of the light-transmitting area 511 but not limited thereto. The area of the light shielding area 512 is larger than the area of the first light reflecting area 513 or the second light reflecting area 514. The areas of the first light reflecting area 513 and the second light reflecting area 514 are respectively larger than the areas of the first upper light emitting surface 211 and the second upper light emitting surface 222.

具體來說，將發光元件的尺寸極小化，以節省觸控模組100內的使用空間，第一反光區513及第二反光區514分別覆蓋第一上方出光面211與第二上方出光面222，反光板50將發光元件產生的光線能量分散並反射至導光板40並傳導至透光區511，達到光效上的最佳化。Specifically, the size of the light-emitting element is minimized to save the use space in the touch module 100. The first reflective area 513 and the second reflective area 514 cover the first upper light-emitting surface 211 and the second upper light-emitting surface 222, respectively. The reflective plate 50 disperses and reflects the light energy generated by the light-emitting element to the light guide plate 40 and transmits it to the light-transmitting area 511 to achieve the optimization of light efficiency.

在本實施例中，觸控模組100更包括擋牆60，擋牆60設置於電路板10並環繞於電路板10之周緣，防止發光元件所產生之光線外漏。另外，雖未繪於圖式，為了防止光線暈染，各出光區41間設有擋板，避免各區域間的發光元件之光線互相影響。In this embodiment, the touch module 100 further includes a barrier wall 60, which is disposed on the circuit board 10 and surrounds the periphery of the circuit board 10 to prevent the light generated by the light emitting element from leaking. In addition, although it is not shown in the drawings, in order to prevent light blooming, a baffle is provided between each light-emitting area 41 to prevent the light from the light-emitting elements in each area from affecting each other.

Specifically, the reflective plate 80 includes a first surface 81, and the first surface 81 is a surface facing the light guide plate 40. The first surface 81 is provided with a light-transmitting area 811, a light-shielding area 812, a first light-reflecting area 813, and a second light-reflecting area 814. The light-transmitting area 811, the light-shielding area 812, the first light-reflecting area 813 and the second light-reflecting area 814 are the same as the above implementation Part of the structure and configuration of the same example will not be repeated. The reflective plate 80 further includes a wall plate 82. The peripheral edge of the wall plate 82 to the reflector plate 80 extends toward one side of the light guide plate 40 and covers the light guide plate 40 and the circuit board 10, and a light-shielding ink layer is printed on the wall plate 82 to Improve the shading effect of the touch module 100.

關於微結構90與發光元件間的配置有多種不同的實施態樣。請參閱圖4並同時參閱圖3，在第一實施例中，於反光板50上定義虛擬軸線A穿過出光區41的中心，第一發光元件21與第二發光元件22設置於虛擬軸線A的兩側。所述虛擬軸線A與各列41A、41B、41C正交並穿過出光區41的中心。當第一發光元件21與第二發光元件22分別設置於對應出光區41的相對兩側邊，第二子區412與第八子區418具有第一微結構91，第一欄41D及第三欄41F具有第二微結構92，其中第一微結構91的網點數量或網點總和面積小於第二微結構92的網點數量或網點總和面積。具體來說，如圖4所示，當第一發光元件21及第二發光元件22設置於相對兩側邊時，第一發光元件21鄰近於第二子區412，而第二發光元件22鄰近於第八子區418，致使光線集中於出光區41的中央，而第二子區412及第八子區418具有較強的光線能量，第一欄41D及第三欄41F的光線能量則較弱，故第二子區412及第八子區418設有網點較疏散的第一微結構91，第一欄41D及第三欄41F則設有網點較緊密的第二微結構92。也就是說設於第二子區412及第八子區418的第一微結構91是以網點較大的間隔排列，設於第一欄41D及第三欄41F的第二微結構92是以網點較小的間隔排列，故第一微結構91的網點數量或網點總和面積將會小於第二微結構92的網點數量或網點總和面積。微結構90的網點間隔排列是隨著光線大小變化，雖然第五子區415在第一實施例中並未配置第一微結構91或第二微結構92，但此僅為最小限度的配置，亦可以根據光線的強弱，配置不同網點間隔的微結構90。There are many different implementation aspects for the arrangement between the microstructure 90 and the light-emitting element. Please refer to FIG. 4 and FIG. 3 at the same time. In the first embodiment, a virtual axis A is defined on the reflector 50 to pass through the center of the light-emitting area 41, and the first light-emitting element 21 and the second light-emitting element 22 are arranged on the virtual axis A On both sides. The virtual axis A is orthogonal to each row 41A, 41B, 41C and passes through the center of the light exit area 41. When the first light-emitting element 21 and the second light-emitting element 22 are respectively disposed on opposite sides of the light-emitting area 41, the second sub-area 412 and the eighth sub-area 418 have the first microstructure 91, the first column 41D and the third The column 41F has a second microstructure 92, wherein the number of dots or the total area of the dots of the first microstructure 91 is smaller than the number of dots or the total area of the dots of the second microstructure 92. Specifically, as shown in FIG. 4, when the first light-emitting element 21 and the second light-emitting element 22 are disposed on opposite sides, the first light-emitting element 21 is adjacent to the second sub-region 412, and the second light-emitting element 22 is adjacent In the eighth sub-area 418, the light is concentrated in the center of the light-emitting area 41, while the second sub-area 412 and the eighth sub-area 418 have stronger light energy, and the light energy of the first column 41D and the third column 41F is higher Therefore, the second sub-region 412 and the eighth sub-region 418 are provided with the first microstructure 91 with relatively scattered dots, and the first column 41D and the third column 41F are provided with the second microstructure 92 with denser dots. That is to say, the first microstructures 91 provided in the second sub-region 412 and the eighth sub-region 418 are arranged with larger intervals of dots, and the second microstructures 92 provided in the first column 41D and the third column 41F are The dots are arranged at smaller intervals, so the number of dots or the total area of the dots of the first microstructure 91 will be smaller than the number of dots or the total area of the dots of the second microstructure 92. The dot spacing arrangement of the microstructure 90 changes with the size of the light. Although the fifth subregion 415 is not configured with the first microstructure 91 or the second microstructure 92 in the first embodiment, this is only a minimum configuration. It is also possible to configure microstructures 90 with different dot intervals according to the intensity of light.

請參閱圖5。圖5為根據一第二實施例，發光元件與網點之配置示意圖。以下實施例與上述實施例相同之元件及結構將不再贅述。在第二實施例中，可以於反光板50上定義虛擬軸線B穿過透光區511的中心，第一發光元件21與第二發光元件22設置於虛擬軸線B的兩側。所述虛擬軸線B以對角的方式穿過透光區511的中心。第一發光元件21與第二發光元件22分別設置於對應出光區41的兩相對角鄰近處，出光區41不具有第一微結構91且僅具有第二微結構92平均分佈。具體來說，如圖5所示，當第一發光元件21及第二發光元件22設置於兩相對角鄰近處時，第一發光元件21鄰近於第一子區411，而第二發光元件22鄰近於第九子區419，致使光線平均分散於出光區41，而因為光線平均且較弱地分散於出光區41，故整個出光區41設有網點較緊密的第二微結構92，而不設有網點較疏散的第一微結構91。也就是說出光區41的第二微結構92是以網點較小的間隔排列。微結構90的網點間隔排列是隨著光線大小變化，舉例來說，第二實施例因為光線平均較弱地分散，故整個出光區41配置了網點較緊密的第二微結構92，但不以此為限，當發光元件的光線能量增加，致使整個出光區41的亮度增強時，出光區41則配置網點較疏散的第一微結構91，亦或是根據光線強弱，配置不同網點間隔的微結構90。Refer to Figure 5. Fig. 5 is a schematic diagram of the arrangement of light-emitting elements and dots according to a second embodiment. The elements and structures of the following embodiments that are the same as those of the above-mentioned embodiments will not be repeated. In the second embodiment, a virtual axis B can be defined on the reflector 50 to pass through the center of the light-transmitting area 511, and the first light-emitting element 21 and the second light-emitting element 22 are arranged on both sides of the virtual axis B. The virtual axis B passes through the center of the light-transmitting area 511 in a diagonal manner. The first light-emitting element 21 and the second light-emitting element 22 are respectively disposed adjacent to two opposite corners corresponding to the light-emitting area 41. The light-emitting area 41 does not have the first microstructures 91 and only has the second microstructures 92 evenly distributed. Specifically, as shown in FIG. 5, when the first light-emitting element 21 and the second light-emitting element 22 are disposed adjacent to two opposite corners, the first light-emitting element 21 is adjacent to the first sub-region 411, and the second light-emitting element 22 Adjacent to the ninth sub-area 419, the light is evenly dispersed in the light-emitting area 41, and because the light is evenly and weakly dispersed in the light-emitting area 41, the entire light-emitting area 41 is provided with a second microstructure 92 with tighter dots. A first microstructure 91 with relatively scattered dots is provided. That is to say, the second microstructures 92 of the light-emitting area 41 are arranged at intervals with smaller dots. The dot spacing arrangement of the microstructure 90 changes with the size of the light. For example, in the second embodiment, because the light is weakly dispersed on average, the entire light exit area 41 is equipped with the second microstructure 92 with tighter dots. This is limited. When the light energy of the light-emitting element increases, resulting in an increase in the brightness of the entire light-emitting area 41, the light-emitting area 41 is configured with the first microstructure 91 with relatively scattered dots, or according to the intensity of light, microstructures with different dot intervals are configured. Structure 90.

請參閱圖6。圖6為根據一第三實施例，發光元件與網點之配置示意圖。在第三實施例中，第一發光元件21與第二發光元件22設置於對應出光區41的同一側邊，第二子區412具有第一微結構91，第七子區417與第九子區419具有第二微結構92，其中第一微結構91的網點數量或網點總和面積小於第二微結構92的網點數量或網點總和面積。具體來說，第一發光元件21與第二發光元件22設置於鄰近於第一列41A的同一側邊，致使光線集中於第二子區412，而第七子區417及第九子區419的光線則相對較弱，故第二子區412設有網點較疏散的第一微結構91，第七子區417及第九子區419設有網點較緊密的第二微結構92。也就是說設於第二子區412的第一微結構91是以網點較大的間隔排列，設於第七子區417及第九子區419的第二微結構92是以網點較小的間隔排列，故第一微結構91的網點數量或網點總和面積將會小於第二微結構92的網點數量或網點總和面積。舉例來說，第三實施例因為微結構90的網點間隔排列是隨著光線大小變化，雖然第一子區411、第三子區413、第二列41B及第八子區418未配置有第一微結構91或第二微結構92但不限於此，根據光線分布情況，亦可於各子區配置不同網點間隔的微結構90。Refer to Figure 6. Fig. 6 is a schematic diagram of the arrangement of light-emitting elements and dots according to a third embodiment. In the third embodiment, the first light-emitting element 21 and the second light-emitting element 22 are arranged on the same side corresponding to the light-emitting area 41, the second sub-area 412 has the first microstructure 91, the seventh sub-area 417 and the ninth sub-area The area 419 has a second microstructure 92, wherein the number of dots or the total area of the dots of the first microstructure 91 is smaller than the number of dots or the total area of the dots of the second microstructure 92. Specifically, the first light-emitting element 21 and the second light-emitting element 22 are arranged on the same side adjacent to the first row 41A, so that light is concentrated in the second sub-region 412, and the seventh sub-region 417 and the ninth sub-region 419 The light from φ is relatively weak, so the second sub-region 412 is provided with a first microstructure 91 with relatively scattered dots, and the seventh sub-region 417 and the ninth sub-region 419 are provided with a second microstructure 92 with relatively dense dots. That is to say, the first microstructures 91 provided in the second sub-region 412 are arranged with larger dots, and the second microstructures 92 provided in the seventh sub-region 417 and the ninth sub-region 419 are arranged with smaller dots. They are arranged at intervals, so the number of dots or the total area of the dots of the first microstructure 91 will be smaller than the number of dots or the total area of the dots of the second microstructure 92. For example, in the third embodiment, because the dot spacing arrangement of the microstructure 90 changes with the size of the light, although the first sub-region 411, the third sub-region 413, the second row 41B, and the eighth sub-region 418 are not configured with the first sub-region 411, the third sub-region 413, and the eighth sub-region 418 One microstructure 91 or second microstructure 92 is not limited thereto. According to the light distribution, microstructures 90 with different dot intervals can also be arranged in each sub-area.

Fig. 7 is a schematic diagram of the arrangement of light-emitting elements and dots according to a fourth embodiment. FIG. 7a is a schematic diagram of the structure of the touch module according to a fourth embodiment. In the fourth embodiment, there is only one light-emitting element, which is represented by the light-emitting element 20 in the following description. The light-emitting element 20 includes an upper light-emitting surface 201, and the light-reflecting plate 50 is provided with a light-reflecting area 515 corresponding to the light-emitting element 20. The rest of the elements and structures that are the same as those in the above embodiment will not be repeated. A virtual axis C is defined on the reflector 50 to pass through the center of the light-transmitting area 511, and the light-emitting element 20 is disposed at one end of the virtual axis C. The light-emitting element 20 is arranged on a side corresponding to the light-emitting area 41 adjacent to the second sub-area 412, the second sub-area 412 has a first microstructure 91, and the seventh sub-area 417 and the ninth sub-area 419 have a second microstructure 92. The number of dots or the total area of the dots of the first microstructure 91 is smaller than the number of dots or the total area of the dots of the second microstructure 92. Specifically, the light-emitting element 20 is disposed adjacent to the second sub-region 412, so that the light is concentrated in the second sub-region 412, while the light in the seventh sub-region 417 and the ninth sub-region 419 is relatively weak, so the second sub-region 412 is provided with a first microstructure 91 with relatively scattered dots, and the seventh sub-region 417 and the ninth sub-region 419 are provided with a second microstructure 92 with relatively dense dots. That is to say, the first microstructures 91 provided in the second sub-region 412 are arranged with larger dots, and the second microstructures 92 provided in the seventh sub-region 417 and the ninth sub-region 419 are arranged with smaller dots. They are arranged at intervals, so the number of dots or the total area of the dots of the first microstructure 91 will be smaller than the number of dots or the total area of the dots of the second microstructure 92. For example, in the fourth embodiment, because the dot spacing arrangement of the microstructure 90 changes with the size of the light, although the first sub-region 411, the third sub-region 413, the second row 41B, and the eighth sub-region 418 are not configured with the first sub-region 411, the third sub-region 413, and the eighth sub-region 418 One microstructure 91 or second microstructure 92 is not limited thereto. According to the light distribution, microstructures 90 with different dot intervals can also be arranged in each sub-area.

請參閱圖8。圖8為根據一第五實施例，發光元件與網點之配置示意圖。在第五實施例中，僅具有一個發光元件，以下僅具有一個發光元件之實施例與上述實施例相同之部分結構配置將不再贅述。於反光板50上定義虛擬軸線D以斜角的方式穿過透光區511的中心，發光元件20設置於虛擬軸線D的一端。發光元件20設置於對應出光區41的一側邊鄰近第一子區411，第一子區411具有第一微結構91，第三子區413與第六子區416具有第二微結構92，其中第一微結構91的網點數量或網點總和面積小於第二微結構92的網點數量或網點總和面積。具體來說，發光元件20設置於鄰近第一子區411，致使光線集中於第一子區411，而第三子區413及第六子區416的光線則相對較弱，故第一子區411設有網點較疏散的第一微結構91，第三子區413及第六子區416設有網點較緊密的第二微結構92。也就是說設於第一子區411的第一微結構91是以網點較大的間隔排列，設於第三子區413及第六子區416的第二微結構92是以網點較小的間隔排列，故第一微結構91的網點數量或網點總和面積將會小於第二微結構92的網點數量或網點總和面積。舉例來說，第五實施例因為微結構90的網點間隔排列是隨著光線大小變化，雖然第二子區412、第四子區414、第五子區415及第三列41C未配置有第一微結構91或第二微結構92但不限於此，根據光線分布情況，亦可於各子區配置不同網點間隔的微結構90。Refer to Figure 8. Fig. 8 is a schematic diagram of the arrangement of light-emitting elements and dots according to a fifth embodiment. In the fifth embodiment, there is only one light-emitting element. The following embodiments with only one light-emitting element have the same structure and configuration as the above-mentioned embodiments, and will not be repeated. A virtual axis D is defined on the reflector 50 to pass through the center of the light-transmitting area 511 at an oblique angle, and the light-emitting element 20 is disposed at one end of the virtual axis D. The light-emitting element 20 is arranged on a side corresponding to the light-emitting area 41 adjacent to the first sub-area 411, the first sub-area 411 has a first microstructure 91, and the third sub-area 413 and the sixth sub-area 416 have a second microstructure 92. The number of dots or the total area of the dots of the first microstructure 91 is smaller than the number of dots or the total area of the dots of the second microstructure 92. Specifically, the light-emitting element 20 is disposed adjacent to the first sub-region 411, so that the light is concentrated in the first sub-region 411, while the light in the third sub-region 413 and the sixth sub-region 416 is relatively weak, so the first sub-region 411 is provided with a first microstructure 91 with relatively scattered dots, and the third sub-region 413 and sixth sub-region 416 are provided with a second microstructure 92 with relatively dense dots. That is to say, the first microstructures 91 provided in the first sub-region 411 are arranged with larger dots, and the second microstructures 92 provided in the third sub-region 413 and the sixth sub-region 416 are arranged with smaller dots. They are arranged at intervals, so the number of dots or the total area of the dots of the first microstructure 91 will be smaller than the number of dots or the total area of the dots of the second microstructure 92. For example, in the fifth embodiment, because the dot spacing arrangement of the microstructure 90 changes with the size of the light, although the second sub-region 412, the fourth sub-region 414, the fifth sub-region 415, and the third row 41C are not configured with the second sub-region 412, the fourth sub-region 414, the fifth sub-region 415, and the third row 41C. One microstructure 91 or second microstructure 92 is not limited thereto. According to the light distribution, microstructures 90 with different dot intervals can also be arranged in each sub-area.

請參閱圖9。圖9為根據一第六實施例，發光元件與網點之配置示意圖。在第六實施例中，僅具有一個發光元件，於反光板50上定義虛擬軸線E以對角的方式穿過透光區511的中心，發光元件20設置於虛擬軸線E的一端。發光元件20設置於對應出光區41的對角鄰近第一子區411，第一子區411具有第一微結構91，第三欄41F具有第二微結構92，其中第一微結構91的網點數量或網點總和面積小於第二微結構92的網點數量或網點總和面積。具體來說，發光元件20設置於出光區的對角處且鄰近第一子區411，致使光線集中於第一子區411，而第三欄41F的光線則相對較弱，故第一子區411設有網點較疏散的第一微結構91，第三欄41F設有網點較緊密的第二微結構92。也就是說設於第一子區411的第一微結構91是以網點較大的間隔排列，設於第三欄41F的第二微結構92是以網點較小的間隔排列，故第一微結構91的網點數量或網點總和面積將會小於第二微結構92的網點數量或網點總和面積。舉例來說，第六實施例因為微結構90的網點間隔排列是隨著光線大小變化，雖然第二子區412、第四子區414、第五子區415、第七子區417及第八子區418未配置有第一微結構91或第二微結構92但不限於此，根據光線分布情況，亦可於各子區配置不同網點間隔的微結構90。Refer to Figure 9. Fig. 9 is a schematic diagram of the arrangement of light-emitting elements and dots according to a sixth embodiment. In the sixth embodiment, there is only one light-emitting element, a virtual axis E is defined on the reflector 50 to pass through the center of the light-transmitting area 511 in a diagonal manner, and the light-emitting element 20 is disposed at one end of the virtual axis E. The light-emitting element 20 is arranged at a diagonal corner corresponding to the light-emitting area 41 and adjacent to the first sub-area 411, the first sub-area 411 has a first microstructure 91, and the third column 41F has a second microstructure 92, wherein the dots of the first microstructure 91 The number or the total area of the dots is smaller than the number of the dots or the total area of the second microstructure 92. Specifically, the light emitting element 20 is arranged at the opposite corner of the light-emitting area and adjacent to the first sub-area 411, so that the light is concentrated in the first sub-area 411, while the light in the third column 41F is relatively weak, so the first sub-area 411 is provided with a first microstructure 91 with relatively scattered dots, and the third column 41F is provided with a second microstructure 92 with relatively dense dots. That is to say, the first microstructures 91 arranged in the first sub-area 411 are arranged at a larger interval of dots, and the second microstructures 92 arranged in the third column 41F are arranged at a smaller interval of dots, so the first microstructure The number of dots or the total area of the dots of the structure 91 will be smaller than the number of dots or the total area of the dots of the second microstructure 92. For example, in the sixth embodiment, the dot spacing arrangement of the microstructure 90 varies with the size of the light, although the second sub-region 412, the fourth sub-region 414, the fifth sub-region 415, the seventh sub-region 417, and the eighth sub-region The sub-region 418 is not configured with the first microstructure 91 or the second microstructure 92 but is not limited to this. According to the light distribution, the microstructures 90 with different dot intervals can also be configured in each sub-region.

綜上所述，根據一些實施例的觸控模組藉由將發光元件的尺寸極小化，以節省觸控模組內的使用空間，反光區覆蓋上方出光面，反光板將發光元件產生的光線能量分散並反射至導光板並傳導至透光區，而導光板上的出光區設置有微結構，微結構隨著發光元件不同位置的擺放，對應光線較強的部份設置網點較疏散的微結構，對應光線較弱的部分設置網點較緊密的微結構，達到光效上的最佳化。In summary, the touch module according to some embodiments minimizes the size of the light-emitting element to save the use space in the touch module. The light-reflecting area covers the upper light-emitting surface, and the reflector removes the light generated by the light-emitting element. The energy is dispersed and reflected to the light guide plate and conducted to the light-transmitting area, and the light-emitting area on the light guide plate is provided with microstructures. The microstructures are placed in different positions of the light-emitting elements, corresponding to the part with stronger light, with more scattered dots. Micro structure, corresponding to the part with weaker light, the micro structure with tighter dots is set to achieve the optimization of light effect.
