[0002] As technology advances with each passing day, the vigorous development of electronic devices has brought many conveniences to human life, so how to make the operation of electronic devices more user-friendly is an important issue. Common input devices of electronic devices include mouse devices, keyboard devices, and trackball devices.

[0003] The designs of input devices on the market are becoming more and more diversified, and the operation interface is becoming more and more simple, convenient and unique. Therefore, various shortcut function keys are derived on various input devices. By forming icons dedicated to specific functions on the shortcut function keys, users can clearly see the functions represented by the shortcut function keys, and then users can switch or start the required functions more quickly through the shortcut function keys.

[0004] Currently, the design of input devices on the market is mainly that a single graphic corresponds to a single shortcut function key, resulting in too many shortcut function keys on the input device. In this case, the user cannot quickly find the shortcut function key they need, or the number of shortcut function keys must be appropriately reduced, which will greatly reduce the convenience of use for the user. Therefore, how to improve the above-mentioned problem has become the focus of relevant personnel in the field. Summary of the invention

The second light-guiding pattern 14 is disposed in the receiving space 100 of the light-isolating structure 10, and the second light-guiding pattern 13 is located in the second region R2 of the receiving space 100.

[0054] The following further describes other detailed structures of the icon display module 1 according to the embodiment of the present invention.

[0055] like Figure 1 and Figure 2 As shown, the light-isolating structure 10 of the present embodiment further includes a first side wall S1, a second side wall S2, a third side wall S4 and a fourth side wall S4. The first side wall S1 of the light-isolating structure 10 is relative to the second side wall S2, the third side wall S3 is relative to the fourth side wall S4, and the third side wall S3 and the fourth side wall S4 are adjacent to the first side wall S1 and the second side wall S2. In the present embodiment, the first side wall S1, the second side wall S2, the third side wall S3 and the fourth side wall S4 jointly define a accommodating space 100 of the light-isolating structure 10, and the first light-isolating portion 101 of the light-isolating structure 10 is disposed on the second side wall S2, that is, the first light-isolating portion 101 extends from the second side wall S2, specifically, the first light-isolating portion 101 extends from the second side wall S2 toward the direction close to the first side wall S1, and there is a spacing G between the first light-isolating portion 101 and the first side wall S1.

[0056] like Figure 1 and Figure 2As shown, the light-isolating structure 10 of the present embodiment further includes a first groove C1 and a second groove C2. The first groove C1 of the light-isolating structure 10 is opened on the first side wall S1, and the first groove C1 and the first light-isolating portion 101 are opposite to each other, and the second groove C2 is opened on the second side wall S2, and the second groove C2 and the first light-isolating portion 101 are adjacent to each other. In the present embodiment, the first light-emitting element 11 of the icon display module 1 is arranged in the first groove C1, that is, the first light-emitting element 11 is arranged at a position opposite to the first light-isolating portion 101, and the second light-emitting element 12 is arranged in the second groove C2, that is, the second light-emitting element 12 is arranged at a position adjacent to the first light-isolating portion 101.

[0057] The following further describes the operation of the icon display module 1 according to the embodiment of the present invention.

[0058] The icon display module 1 of this embodiment can display different icons on the same target object 2 in different usage states. Figure 1 and Figure 3 As shown, in a usage state, the first light emitting element 11 of the icon display module 1 emits a first light ray L1. Since the first light ray L1 will not be blocked by the first light isolation portion 101, the first light ray L1 will pass through the first area R1 and the second area R2 of the accommodating space 102 at the same time. At this time, the first light ray L1 is simultaneously irradiated on the first light guide pattern 13 located in the first area R1 and the second light guide pattern 14 located in the second area R2, so that the first light guide pattern 13 and the second light guide pattern 14 simultaneously guide the first light ray L1 and project the first light ray L1 onto the target object 2, thereby simultaneously displaying the first icon P1 corresponding to the first light guide pattern 13 and the second icon P2 corresponding to the second light guide pattern 14 on the target object 2.

[0059] like Figure 2 and Figure 4 As shown, in another usage state, the second light-emitting element 12 of the icon display module 1 emits a second light ray L2. Since the second light ray L2 will be blocked by the first light-isolating portion 101, the second light ray L2 only passes through the first area R1 of the accommodating space 102. At this time, the second light ray L2 only irradiates the first light guide pattern 13 located in the first area R1, so that the first light guide pattern 13 guides the second light ray L2 and projects the second light ray L2 onto the target object 2, thereby displaying the first icon P1 corresponding to the first light guide pattern 13 on the target object 2.

[0060] In the present embodiment, the color of the first light L1 emitted by the first light-emitting element 11 of the icon display module 1 is different from the color of the second light L2 emitted by the second light-emitting element 12. For example, the color of the first light L1 is red, and the color of the second light L2 is green, but the present invention is not limited thereto. When the first light-emitting element 11 is in use and emits the first light L1, after the first light guide pattern 13 and the second light guide pattern 14 simultaneously project the first light L1 onto the target object 2, the red first icon P1 and the second icon P2 will be displayed on the target object 2. When the second light-emitting element 12 is in use and emits the second light L2, after the first light guide pattern 13 projects the second light L2 onto the target object 2, the green first icon P1 will be displayed on the target object 2. In addition, in the present embodiment, the first light-emitting element 11 and the second light-emitting element 12 are, for example, light-emitting diodes, but the present invention is not limited thereto.

[0061] It should be noted that the icon display module 1 of the present embodiment is configured in an input device, and the input device is, for example, a keyboard device, a mouse device, or a trackball device, etc. Taking a keyboard device as an example, the keyboard device includes a plurality of keys, which can be classified into general keys, numeric keys, and shortcut function keys, etc., which are respectively used by the user to press with a finger to make the keyboard device generate corresponding key signals to the computer, thereby making the computer execute corresponding functions, for example, general keys are used to input symbols such as English letters, numeric keys are used to input numbers, and shortcut function keys are used to provide various shortcut functions, and the icon display module 1 shown in the present embodiment is correspondingly configured below the shortcut function keys (i.e., the above-mentioned target object 2) of the keyboard device.

[0062] As mentioned above, since the icon display module 1 of this embodiment can display different icon combinations on the same target object 2 under different usage states, when the icon display module 1 of this embodiment is configured on a keyboard device, the shortcut function key on the keyboard device can be designed to trigger two different shortcut functions. For example, when the shortcut function key is in a state that can trigger the first shortcut function (for example, disabling the webcam lens function), the icon display module 1 will display an icon that corresponds to the first shortcut function on the shortcut function key (such as Figure 3 When the shortcut function key is in a state where the second shortcut function can be triggered (for example, enabling the webcam lens function), the icon display module 1 displays an icon corresponding to the second shortcut function on the shortcut function key (such as Figure 4 The first icon P1 is shown.

[0063] It is worth mentioning that the above-mentioned shortcut function key can switch between the triggerable first shortcut function state and the triggerable second shortcut function state through the switching signal sent by other keys on the input device, and while switching between the two states, the icon display module 1 displays the corresponding icon on the shortcut function key. For example, when the shortcut function key switches from the triggerable first shortcut function state to the triggerable second shortcut function state according to the switching signal, the icon display module 1 simultaneously controls the second light emitting element 12 to emit the second light L2, so that the first light guide pattern 13 located in the first area R1 guides the second light L2 and projects the second light L2 onto the shortcut function key, and then the first icon P1 corresponding to the second shortcut function is displayed on the shortcut function key.

[0064] See also Figures 5 to 8 , Figure 5 FIG. 4 is a schematic diagram of the structure of an icon display module in a use state according to another embodiment of the present invention. Figure 6 FIG. 4 is a schematic structural diagram of an icon display module in another use state according to another embodiment of the present invention. Figure 7 for Figure 5 The icon display module shown displays an icon on a target object. Figure 8 for Figure 6 The icon display module 1a of this embodiment is used to display an icon on a target object. Figure 1 and Figure 2 The icon display module 1 shown is similar, the difference is that the icon display module 1a of this embodiment also includes a third light guide pattern 15, and the light isolation structure 10a also includes a second light isolation portion 102. According to the above-mentioned newly added components, the structural configuration of the icon display module 1a of this embodiment is slightly different, as described below.

[0065] like Figure 5 and Figure 6 As shown, the first light isolation portion 101 and the second light isolation portion 102 of the present embodiment define a first region R1, a second region R2 and a third region R3 in the accommodation space 100 of the light isolation structure 10a. The first light guide pattern 13 is located in the first region R1 of the accommodation space 100, the second light guide pattern 14 is located in the second region R2 of the accommodation space 100, and the third light guide pattern 15 is located in the third region R3 of the accommodation space 100.

[0066] Based on the above, the first light-isolating portion 101 of the light-isolating structure 10a is configured on the second side wall S2, that is, the first light-isolating portion 101 extends from the second side wall S2, and the second light-isolating portion 102 is configured on the first side wall S1, that is, the second light-isolating portion 102 extends from the second side wall S2. Specifically, the first light-isolating portion 101 extends from the second side wall S2 toward the direction close to the first side wall S1, and the second light-isolating portion 102 extends from the first side wall S1 toward the direction close to the second side wall S2, and there is a spacing G' between the first light-isolating portion 101 and the second light-isolating portion 102.

[0067] As described above, the first groove C1 of the light isolation structure 10a is formed on the first side wall S1, and the first groove C1 is adjacent to the second light isolation portion 102, and the second groove C2 is formed on the second side wall S2, and the second groove C2 is adjacent to the first light isolation portion 101. In this embodiment, the first light emitting element 11 of the icon display module 1 is disposed in the first groove C1, that is, the first light emitting element 11 is disposed at a position adjacent to the second light isolation portion 102, and the second light emitting element 12 is disposed in the second groove C2, that is, the second light emitting element 12 is disposed at a position adjacent to the first light isolation portion 101.

[0068] like Figure 5 and Figure 7 As shown, in a usage state, the first light emitting element 11 of the icon display module 1a emits a first light ray L1. Since the first light ray L1 is blocked by the second light isolation portion 102, the first light ray L1 only passes through the first area R1 and the second area R2 of the accommodating space 102. At this time, the first light ray L1 is simultaneously irradiated on the first light guide pattern 13 located in the first area R1 and the second light guide pattern 14 located in the second area R2, so that the first light guide pattern 13 and the second light guide pattern 14 simultaneously guide the first light ray L1 and project the first light ray L1 onto the target object 2, thereby simultaneously displaying the first icon P1' corresponding to the first light guide pattern 13 and the second icon P2' corresponding to the second light guide pattern 14 on the target object 2.

[0069] like Figure 6 and Figure 8As shown, in another usage state, the second light-emitting element 12 of the icon display module 1a emits a second light ray L2. Since the second light ray L2 will be blocked by the first light-isolating portion 101, the second light ray L2 only passes through the first area R1 and the third area R3 of the accommodating space 102. At this time, the second light ray L2 only shines on the first light guide pattern 13 located in the first area R1 and the third light guide pattern 15 located in the third area R3, so that the first light guide pattern 13 and the third light guide pattern 15 simultaneously guide the second light ray L2 and project the second light ray L2 onto the target object 2, thereby simultaneously displaying the first icon P1' corresponding to the first light guide pattern 13 and the third icon P3' corresponding to the third light guide pattern 15 on the target object 2.

[0070] It should be particularly noted that the combination of the above-mentioned first icon P1' and the second icon P2', for example, corresponds to the state of the shortcut function key being in a shortcut function that can trigger adjusting the volume to increase, and the combination of the above-mentioned first icon P1' and the third icon P3', for example, corresponds to the state of the shortcut function key being in a shortcut function that can trigger adjusting the volume to decrease.

[0071] In summary, the icon display module of the embodiment of the present invention can display icons of different combinations on the same function shortcut key. Therefore, when the icon display module of this embodiment is configured on an input device, the shortcut function key on the input device can be designed to trigger two different shortcut functions. In this way, the number of shortcut function keys on the input device can be greatly reduced, allowing users to quickly memorize and find the location of the shortcut function keys. In addition to effectively reducing costs, the user's operating convenience can be greatly improved. On the other hand, since the shortcut function key is designed to trigger two different shortcut functions, from the perspective of product design, more shortcut function keys can be added to the input device, which can also improve the user's operating convenience.
