[0024] In summary, the present invention sets a first light guide area and a second light guide area in the same light guide layer. The light emitted by the first light source will be guided to the first light-transmitting area of ​​the panel through the first light guide area, thereby forming a light-emitting pattern corresponding to the first light-transmitting area (for example, a touch icon). In addition, when the touch module senses that the first light-transmitting area is touched, the controller will control the second light source to emit light. At this time, the light emitted by the second light source will be guided to the second light-transmitting area of ​​the panel through the second light guide area, thereby forming a light-emitting effect corresponding to the second light-transmitting area as a prompt for the touch action. The user can confirm whether the touch action has been executed by the prompt of this touch action. Furthermore, since the first light guide area and the second light guide area are arranged in the same light guide layer (that is, the first light guide area and the second light guide area are located in the same plane), therefore, the first light guide area and the second light guide area will not increase the overall thickness of the luminous touch panel, which is conducive to the thin design of the luminous touch panel. In addition, the same light guide layer containing multiple light guide areas is also easier to assemble. Since the first light-transmitting area and the second light-transmitting area as the light-emitting pattern are formed on the panel, the resolution is better than that of the pattern formed on the traditional light guide plate.

Figure 3 for Figure 1 A partial cross-sectional schematic diagram of the luminous touch panel 1 in FIG. Figure 4 Schematic diagrams of three different styles of the second light-transmitting area 102 .

[0035] like Figures 1 to 3 As shown, the luminous touch panel 1 includes a panel 10, a light guide layer 12 and a circuit board 14. The luminous touch panel 1 can be applied to a touch function row or other devices with touch functions. The panel 10 includes a first light-transmitting area 100 and a second light-transmitting area 102. In the present embodiment, the panel 10 may include a light-transmitting layer 10a and a light-shielding layer 10b, wherein the light-shielding layer 10b is disposed on one side of the light-transmitting layer 10a. In the present embodiment, the light-shielding layer 10b may be disposed on the side of the light-transmitting layer 10a facing the circuit board 14. In another embodiment, the light-shielding layer 10b may also be disposed on the other side of the light-transmitting layer 10a away from the circuit board 10. In other words, the light-shielding layer 10b may be disposed on one of the opposite sides of the light-transmitting layer 10a, depending on the actual application. The light-transmitting layer 10a may be glass, polycarbonate (PC) or other light-transmitting panels. The light shielding layer 10b can be ink or other light shielding materials, and can be formed on the light transparent layer 10a by printing or other methods. The light shielding layer 10b is formed with a first light transparent area 100 and a second light transparent area 102, wherein the first light transparent area 100 and the second light transparent area 102 are arranged alternately.

[0036] like Figure 1 and Figure 2As shown, in this embodiment, the panel 10 may include a plurality of first light-transmitting areas 100 and a plurality of second light-transmitting areas 102, each first light-transmitting area 100 corresponds to each second light-transmitting area 102 one by one and forms a plurality of groups of light-transmitting areas, each group of light-transmitting areas includes a first light-transmitting area 100 and a corresponding second light-transmitting area 102. The pattern of each first light-transmitting area 100 may correspond to its corresponding touch function for user operation. Furthermore, each first light-transmitting area 100 and the second light-transmitting area 102 are formed via a light-shielding layer 10b (for example, by printing or the like), which can achieve a higher pattern fineness (or resolution), and has a better visual effect than the pattern traditionally made on the light guide plate.

[0037] The light guide layer 12 is located below the panel 10. The light guide layer 12 includes a first light guide area 120 and a second light guide area 122, wherein the first light guide area 120 overlaps with the first light-transmitting area 100, and the second light guide area 122 overlaps with the second light-transmitting area 102. In the present embodiment, the first light guide area 120 and the second light guide area 122 are located in the same plane. For example, the first light guide area 120 and the second light guide area 122 may be two light guide plates spaced and arranged side by side. The two light guide plates may be connected or not connected, depending on the actual application. The light guide layer 12 may further include a shading structure 124, which is at least located between the first light guide area 120 and the second light guide area 122. The shading structure 124 may be a light absorbing element (for example, a black sponge, a black mask, etc.) or a reflective element to prevent the light in the first light guide area 120 and the second light guide area 122 from interfering with each other. In this embodiment, the first light guide region 120 may have a first microstructure 1200, and the second light guide region 122 may have a second microstructure 1220, wherein the first microstructure 1200 overlaps with the first light-transmitting region 100, and the second microstructure 1220 overlaps with the second light-transmitting region 102. The first microstructure 1200 is used to reflect light toward the first light-transmitting region 100, and the second microstructure 1220 is used to reflect light toward the second light-transmitting region 102.

[0038] The circuit board 14 is located below the light guide layer 12. The circuit board 10 may be a printed circuit board (PCB) or other circuit boards that can provide electrical connections, wherein the circuit board 10 may include a substrate and a circuit on the substrate. In addition, the circuit board 14 includes a controller 140, a touch module 142, a first light source 144, and a second light source 146. The touch module 142 overlaps with the first light-transmitting area 100 to sense whether the first light-transmitting area 100 is touched. In addition, the shading structure 124, the second microstructure 1220, and the second light-transmitting area 102 do not overlap with the touch module 142. The first light source 144 is located on one side of the first light guide area 120, and the second light source 146 is located on one side of the second light guide area 122. The controller 140 controls the operation of the touch module 142, the first light source 144, and the second light source 146 via the circuit of the circuit board 10. The touch module 142 is electrically connected to the circuit of the circuit board 10, and generates a sensing signal according to the user's operation, and outputs the sensing signal to the system end (for example, a computer) through the circuit. In actual operation, the touch module 142 may include an integrated circuit chip (IC die) and a package covering the integrated circuit chip. The touch module 142 may include a fingerprint recognition module and any type of touch module, or any combination thereof. The first light source 144 and the second light source 146 may be light emitting diodes (LEDs) or other elements that can emit light.

[0039] In one embodiment, the light shielding structure 124, the first light guide area 120 and the second light guide area 122 can be manufactured separately first. The light shielding structure 124 is an opaque plate and has a profile similar to the panel 10. The light shielding structure 124 has hollows corresponding to the first light guide area 120, the second light guide area 122, the first light source 144 and the second light source 146. The first light guide area 120 and the second light guide area 122 are fixed on the light shielding structure 124 through the corresponding hollows, and may not exceed the upper and lower surfaces of the light shielding structure 124 to form the light guide layer 12. In another embodiment, a whole light guide plate with a profile similar to the panel 10 can be formed first, with hollows corresponding to the first light source 144 and the second light source 146, and then the light shielding structure 124 is manufactured in other areas except the first light guide area 120 and the second light guide area 122 by printing or other methods to form the light guide layer 12. The light guide layer 12 facilitates its assembly with the panel 10 and the circuit board 14. When assembled, the first light source 144 and the second light source 146 are located in the corresponding hollows in the light shielding structure 124 and on one side of the corresponding light guide area. In addition, the first light guide area 120 and the second light guide area 122 can be located in the same plane and do not exceed the upper and lower surfaces of the light shielding structure 124, so as not to increase the overall thickness of the luminous touch panel 1.

[0040] In this embodiment, a reflective sheet 16 may be disposed on the circuit board 14. The reflective sheet 16 may be used to recycle light or assist in light emission. Specifically, the reflective sheet 16 may help guide the light that escapes from the first light guide area 120 and the second light guide area 122 into the first light guide area 120 and the second light guide area 122 for recycling, thereby helping to improve the light emission effect. In one embodiment, the reflective sheet 16 may be disposed on a side of the circuit board 14 that faces the light guide layer 12, and does not overlap with the touch module 142, the first light source 144, and the second light source 146.

[0041] When the luminous touch panel 1 is turned on, the controller 140 controls the first light source 144 to emit light, so that the first light guide area 120 guides the light emitted by the first light source 144 to the first light-transmitting area 100 to emit light, thereby forming a light-emitting pattern (for example, a touch icon) corresponding to the first light-transmitting area 100. In this way, the user can accurately find the desired touch position according to the light-emitting pattern. In this embodiment, when the first light-transmitting area 100 is not touched, the second light source 146 does not emit light. In other words, when the user does not touch the first light-transmitting area 100, only the first light-transmitting area 100 will emit light, and the second light-transmitting area 102 will not emit light.

[0042] When the user wants to execute the touch function corresponding to the first light-transmitting area 100, the user can touch the first light-transmitting area 100 with the finger 3. Figure 1 As shown. When the touch module 142 senses that the first light-transmitting area 100 is touched, the controller 140 will control the second light source 146 to emit light according to the sensing signal output by the touch module 142, so that the second light guide area 122 guides the light emitted by the second light source 146 to the second light-transmitting area 102 to emit light, thereby forming a luminous effect corresponding to the second light-transmitting area 102 as a prompt for the touch action. The user can use the prompt of this touch action to confirm whether the touch action has been executed. In this embodiment, the panel 10 can define a touch area 104 corresponding to the first light-transmitting area 100, and the second light-transmitting area 102 is located outside the touch area 104. When the user performs a touch operation on the touch area 104 with the finger 3, the luminous effect corresponding to the second light-transmitting area 102 will not be blocked by the finger 3. In this way, the user can be prompted whether the touch action has been executed. As shown Figure 4 As shown, the second light-transmissive region 102 may be a corresponding prompt pattern located outside the touch region 104 , such as at least one horizontal bar pattern, at least one vertical bar pattern and / or at least one corner pattern, depending on actual applications.

[0043] When the second light source 146 is turned on and the touch module 142 senses that the first light-transmitting area 100 is no longer touched, the controller 140 turns off the second light source 146. Specifically, when the user moves the finger 3 away from the first light-transmitting area 100 (that is, the finger 3 no longer touches the first light-transmitting area 100), the controller 140 turns off the second light source 146, so that the light emitted from the second light-transmitting area 102 disappears. Figure 1 Thus, only when the touch module 142 senses that the first light-transmitting area 100 is touched, the second light-transmitting area 102 will emit light to prompt the user whether the touch action has been performed.

[0044] See also Figure 5 as well as Figure 6 , Figure 5 is a schematic diagram of touch operation of a light-emitting touch panel 1' according to another embodiment of the present invention, Figure 6 for Figure 5 A partial exploded schematic diagram of the luminous touch panel 1' in FIG.

[0045] The main difference between the luminous touch panel 1' and the above-mentioned luminous touch panel 1 is that the panel 110 of the luminous touch panel 1' further includes a third light-transmitting area 106, the light-guiding layer 12 of the luminous touch panel 1' further includes a third light-guiding area 126, and the circuit board 14 of the luminous touch panel 1' further includes a third light source 148, wherein the third light-guiding area 126 overlaps with the third light-transmitting area 106, and the third light source 148 is located on one side of the third light-guiding area 126, as shown in FIG. Figure 5 and Figure 6 The third light-transmitting area 106 can be formed in the above-mentioned light-shielding layer 10b, and the third light source 148 can be a light-emitting diode or other element that can emit light. It should be noted that, Figure 5-Figure 6 Zhongyu Figure 1-Figure 3 The components with the same reference numerals shown in the figure have roughly the same working principles and structural configurations, which will not be described in detail here. Figure 5 As shown, in this embodiment, the panel 10 may include a plurality of first light-transmitting areas 100, a plurality of second light-transmitting areas 102, and a plurality of third light-transmitting areas 106. Each first light-transmitting area 100, each second light-transmitting area 102, and each third light-transmitting area 106 correspond to each other one by one and form a plurality of groups of light-transmitting areas. Each group of light-transmitting areas includes a first light-transmitting area 100 and a corresponding second light-transmitting area 102 and a corresponding third light-transmitting area 106. The pattern of each first light-transmitting area 100 may correspond to its corresponding touch function for user operation.

[0046] In this embodiment, the second light-transmitting area 102 and the third light-transmitting area 106 may be located on two adjacent sides of the first light-transmitting area 100, but the present invention is not limited thereto. In this embodiment, the first light-guiding area 120, the second light-guiding area 122 and the third light-guiding area 126 may be located on the same plane. For example, the first light-guiding area 120, the second light-guiding area 122 and the third light-guiding area 126 may be three light-guiding plates spaced and arranged side by side. The three light-guiding plates may be connected or not connected, depending on the actual application. Figure 6 As shown, the third light guide area 126 can connect the first light guide area 120 and the second light guide area 122, but is not limited to this. In addition, the above-mentioned light shading structure 124 separates the first light guide area 120, the second light guide area 122 and the third light guide area 126 to avoid mutual interference between the light in the first light guide area 120, the second light guide area 122 and the third light guide area 126. In the present embodiment, the third light guide area 126 may have a third microstructure 1260, wherein the third microstructure 1260 overlaps with the third light-transmitting area 106 and does not overlap with the touch module 142. The third microstructure 1260 is used to reflect light toward the third light-transmitting area 106. The manufacturing method of the first light guide area 120, the second light guide area 122, the third light guide area 126, and the light shading structure 124 can be the same as Figure 1-Figure 3 The embodiments are similar and will not be described again here.

[0047] When the luminous touch panel 1 is turned on, the controller 140 controls the first light source 144 to emit light, so that the first light guide area 120 guides the light emitted by the first light source 144 to the first light-transmitting area 100 to emit light, thereby forming a light-emitting pattern (for example, a touch icon) corresponding to the first light-transmitting area 100. In this way, the user can accurately find the desired touch position according to the light-emitting pattern. In this embodiment, when the first light-transmitting area 100 is not touched, the second light source 146 and the third light source 148 do not emit light. In other words, when the user does not touch the first light-transmitting area 100, only the first light-transmitting area 100 will emit light, and the second light-transmitting area 102 and the third light-transmitting area 106 will not emit light.

[0048] When the user wants to execute the touch function corresponding to the first light-transmitting area 100, the user can touch the first light-transmitting area 100 with the finger 3. Figure 5As shown. When the touch module 142 senses that the first light-transmitting area 100 is touched, the controller 140 will control the second light source 146 and the third light source 148 to emit light according to the sensing signal output by the touch module 142. At this time, the second light-guiding area 122 will guide the light emitted by the second light source 146 to the second light-transmitting area 102 to emit light, thereby forming a luminous effect corresponding to the second light-transmitting area 102 as a prompt for the touch action. The user can use this prompt for the touch action to confirm whether the touch action has been executed. At the same time, the third light-guiding area 126 will guide the light emitted by the third light source 148 to the third light-transmitting area 106 to emit light, thereby forming a luminous pattern corresponding to the third light-transmitting area 106 (for example, a diagram corresponding to the touch function of the first light-transmitting area 100), that is, the third light-guiding area 106 can be used as a prompt pattern for the current state of the touch function corresponding to the first light-transmitting area 100.

[0049] When the second light source 146 is turned on and the touch module 142 senses that the first light-transmitting area 100 is no longer touched, the controller 140 turns off the second light source 146. Specifically, when the user moves the finger 3 away from the first light-transmitting area 100 (that is, the finger 3 no longer touches the first light-transmitting area 100), the controller 140 turns off the second light source 146, so that the light emitted from the second light-transmitting area 102 disappears. Figure 5 As shown. Thus, only when the touch module 142 senses that the first light-transmitting area 100 is touched, the second light-transmitting area 102 will emit light to prompt the user whether the touch action has been performed. In addition, when the third light source 148 is turned on and the touch module 142 senses that the first light-transmitting area 100 is no longer touched, the controller 140 does not turn off the third light source 148, so that the third light-transmitting area 106 continues to emit light. Thus, the user can know the state of the touch function corresponding to the first light-transmitting area 100 according to the light-emitting pattern of the third light-transmitting area 106. For example, the touch function corresponding to the first light-transmitting area 100 can be speaker volume adjustment, and the light-emitting pattern of the third light-transmitting area 106 can be a mute icon. When the third light-transmitting area 106 emits light, it indicates that the speaker is in a mute state.

[0050] When the third light source 148 is turned on and the touch module 142 senses that the first light-transmitting area 100 is touched again, the controller 140 will turn off the third light source 148. Specifically, when the third light source 148 is turned on and the user touches the first light-transmitting area 100 with the finger 3 again, the controller 140 will turn off the third light source 148, so that the light emitted by the third light-transmitting area 106 disappears. Figure 5 For example, when no light is transmitted from the third light-transmitting area 106, it indicates that the speaker is in a non-mute state.

[0051] In summary, the present invention sets a first light guide area and a second light guide area in the same light guide layer. The light emitted by the first light source will be guided to the first light-transmitting area of ​​the panel through the first light guide area, thereby forming a light-emitting pattern corresponding to the first light-transmitting area (for example, a touch icon). In addition, when the touch module senses that the first light-transmitting area is touched, the controller will control the second light source to emit light. At this time, the light emitted by the second light source will be guided to the second light-transmitting area of ​​the panel through the second light guide area, thereby forming a light-emitting effect corresponding to the second light-transmitting area as a prompt for the touch action. The user can confirm whether the touch action has been executed by the prompt of this touch action. Furthermore, the first light guide area and the second light guide area can be set in the same light guide layer (that is, the first light guide area and the second light guide area are located in the same plane), so the first light guide area and the second light guide area will not increase the overall thickness of the luminous touch panel, which is conducive to the thin design of the luminous touch panel. In addition, the same light guide layer containing multiple light guide areas is also easier to assemble. Since the first light-transmitting area and the second light-transmitting area as the light-emitting pattern are formed on the panel, the resolution is better than that of the pattern formed on the traditional light guide plate.

[0052] Of course, the present invention may have many other embodiments.
