Figure 4 for Figure 1 A top view of the shading sheet 10 disposed in the second backlit keyboard 14. Figure 5 for Figure 4 FIG. 1 is a schematic cross-sectional exploded view of the second backlit keyboard 14 along the section line II-II, wherein in order to clearly show the corresponding positional relationship between the shading sheet 10 and the first language key combination 18 of the first backlit keyboard 12 and the second language key combination 22 of the second backlit keyboard 14, the first backlit keyboard 12 and the first language key combination 18 are Figure 2 The second backlit keyboard 14 and the second language key combination 22 are shown in bold dashed lines. Figure 4 It is shown briefly by a thick dotted line. Figures 1 to 5 As shown, the shading sheet 10 can be applied to the first backlit keyboard 12 and the second backlit keyboard 14 for shading and transmitting light. The first backlit keyboard 12 includes a first backlight module 16 and a first language key combination 18 (including a plurality of keys, such as W, A, S, D, Enter, etc., Figure 2 The second backlight keyboard 14 includes a second backlight module 20 and a second language key combination 22 (including a plurality of keys, such as W, A, S, D, Enter, etc., in Figure 4 In this way, the light generated by the first backlight module 16 can be incident on the first language key combination 18 through the shading sheet 10, and the light generated by the second backlight module 20 can be incident on the second language key combination 22 through the shading sheet 10, so that the symbols on the upper surfaces of the first language key combination 18 and the second language key combination 22 produce a luminous effect.

[0024] The following is an example of the key configuration of the first language key combination 18 corresponding to the British language. Figure 2 As shown, the symbol on the first key 24 in the first language key combination 18 is , the symbol on the second button 26 in the first language button combination 18 is \. The position of the shading sheet 10 corresponding to the first button 24 and the second button 26 has a first light exit area configuration 331. Taking the button configuration corresponding to the Japanese language of the second language button combination 22 as an example, the design of the shading sheet 10 is described in detail. Figure 1 to Figure 5 It can be seen that at least one pair of adjacent keys in the first language key combination 18 (at Figure 2 The position of the first key 24 and the second key 26 (represented by a pair of adjacent first keys 24 and second keys 26) on the first backlit keyboard 12 substantially overlaps with the position of the third key 28 in the second language key combination 22 on the second backlit keyboard 14, and the sum of the pressing areas of the adjacent first keys 24 and second keys 26 is substantially the same as the pressing area of ​​the third key 28. The first language key combination 18 further includes a fourth key 23, and the position of the fourth key 23 on the first backlit keyboard 12 substantially overlaps with the positions of the fifth key 25, the sixth key 27 and the seventh key 29 in the second language key combination 22 on the second backlit keyboard 14. The shading sheet 10 has a second light emitting area configuration 332 corresponding to the fourth key 23 in the first language key combination 18 (or is considered to correspond to the fifth key 25, the sixth key 27 and the seventh key 29 in the second language key combination 22), wherein the fourth key 23 can be a blank key, and one of the fifth key 25, the sixth key 27 and the seventh key 29 can be a blank key (in Figure 4 In the figure, key 29 represents the blank key, but is not limited to this).

[0025] The light shielding film 10 includes a light-transmitting substrate 30 and a light shielding layer 32. Figure 3 As shown, the transparent substrate 30 is disposed between the first backlight module 16 and the first language key combination 18, or as shown in FIG. Figure 5 As shown, the light shielding layer 32 is disposed between the second backlight module 20 and the second language key combination 22. The light shielding layer 32 is formed on the light-transmitting substrate 30, preferably by printing with white ink. In addition, in order to improve the visual appearance of the entire keyboard and prevent users from seeing the white ink in the gaps between the keys, a layer of black ink can be applied on top of the white ink. Figure 1 As shown, the first light exiting area configuration 331 has a light shielding section 34 for reducing light leakage between the first key 24 and the second key 26. The light shielding section 34 further includes at least one light exiting groove 40 (at Figure 1 Two are shown in the figure, but the present invention is not limited thereto), thereby, part of the light can be intentionally allowed to illuminate the gap between the first key 24 and the second key 26 from the light exit slot 40 to produce a continuous halo effect.

[0026] According to the above design, when the shading sheet 10 is disposed between the first backlight module 16 and the first language key combination 18 (eg Figure 3As shown in FIG. 1 ), the light emitted by the first backlight module 16 can be incident on the first key 24 and the second key 26 through the first light emitting area configuration 331, so that the symbols on the first key 24 and the second key 26 produce a luminous effect; on the other hand, when the shading sheet 10 is disposed between the second backlight module 20 and the second language key combination 22 (as shown in FIG. 1 ), the light emitted by the first backlight module 16 can be incident on the first key 24 and the second key 26 respectively through the first light emitting area configuration 331, so that the symbols on the first key 24 and the second key 26 produce a luminous effect; on the other hand, when the shading sheet 10 is disposed between the second backlight module 20 and the second language key combination 22 (as shown in FIG. Figure 5 As shown in FIG. 1 , the light emitted by the second backlight module 20 can also be incident on the third key 28 through the first light emitting area configuration 331, so that the symbol on the third key 28 produces a luminous effect. Figure 4 The symbols on the fifth key 25, the sixth key 27 and the seventh key 29 in the second language key combination 22 produce a luminous effect.

[0027] In summary, no matter whether the shading sheet 10 is arranged in the first backlight keyboard 12 having the configuration of the first language key combination 18, or is arranged in the second backlight keyboard 14 having the configuration of the second language key combination 22, the light emitted by the first backlight module 16 can be incident on the first key 24 and the second key 26 in the first language key combination 18 respectively through the light exit areas 36 and 38 on the shading sheet 10, and the light emitted by the second backlight module 20 can also be incident on the third key 28 in the second language key combination 22 through the light exit areas 36 and 38 on the shading sheet 10, and the light emitted by the first backlight module 16 will also be blocked by the shading section 34 on the shading sheet 10 to reduce light leakage between the first key 24 and the second key 26. In this way, the present invention can produce the effect that the first light emitting area configuration 331 and the second light emitting area configuration 332 of the shading film 10 can be applied to the first backlit keyboard 12 and the second backlit keyboard 14, thereby effectively solving the problem mentioned in the prior art that the shading films used on backlit keyboards of different languages ​​cannot be shared, thereby reducing the cost required for manufacturing the backlit keyboards.

[0028] In addition, the light emitting area design of the light shielding sheet 10 of the present invention can be applied to the third backlight keyboard, see Figure 1 as well as Figure 6 , Figure 6 for Figure 1 FIG. 1 is a top view of a shading sheet 10 disposed in a third backlit keyboard 42, wherein in order to clearly show the corresponding positional relationship between the shading sheet 10 and the third language key combination 46 of the third backlit keyboard 42, the third backlit keyboard 42 and the third language key combination 46 are arranged in a Figure 6 It is shown briefly by a thick dotted line. Figure 1 and Figure 6 As shown, the shading sheet 10 can be applied to the third backlight keyboard 42 for selective light transmission and light shielding. The third backlight keyboard 42 includes a backlight module (not shown, and its related description can be referred to Figure 3as well as Figure 5 and the third language key combination 46 (including a plurality of keys, such as W, A, S, D, Enter, etc., in Figure 6 In this way, the light generated by the backlight module of the third backlight keyboard 42 can be incident on the third language key combination 46 through the multiple light emitting areas of the light shielding sheet 10, so that the symbols on the third language key combination 46 produce a luminous effect.

[0029] Here, the key configuration of the third language key combination 46 corresponding to the American language is taken as an example. The design of the light shielding sheet 10 is described in detail. Figure 1 , Figure 4 and Figure 6 It can be seen that at least one pair of adjacent keys in the second language key combination 22 ( Figure 4 The positions of the keys 64 and 66 in the second backlit keyboard 14 (represented by a pair of adjacent keys 64 and 66 in the third language key combination 46) on the second backlit keyboard 14 substantially overlap with the positions of the keys 68 and 70 in the third language key combination 46 on the third backlit keyboard 42, and the adjacent keys 64 and 66 in the second language key combination 22 and the adjacent keys 68 and 70 in the third language key combination 46 have substantially the same pressing area. The shading sheet 10 has a third light emitting area configuration 333 corresponding to the keys 64 and 66 of the second backlit keyboard 14 (and also corresponding to the keys 68 and 70 of the third backlit keyboard 42), so that the light from the backlight module can illuminate the symbols on the keys 64, 66, 68, and 70. The third light emitting area configuration 333 is L-shaped in appearance. One of the keys 64 and 66 includes an Enter key (in Figure 4 In the example, key 64 represents the Enter key, but is not limited thereto), and one of keys 68 and 70 includes the Enter key (in Figure 6 In the example, key 70 represents the Enter key, but the present invention is not limited to this).

[0030] In addition, by Figure 2 It can be seen that when the shading sheet 10 is disposed in the first backlight keyboard 12, the light of the first backlight module 16 can also illuminate the symbols on the keys 31 and 33 in the first language key combination 18 through the third light emitting area configuration 333, and one of the keys 31 and 33 includes the Enter key (in Figure 2 In the example, key 31 represents the Enter key, but is not limited to this). In addition, Figure 6 It can be seen that when the shading film 10 is set in the third backlight keyboard 42, the light of the backlight module of the third backlight keyboard 42 can also illuminate the symbols on the key 72 in the third language key combination 46 through the first light emitting area configuration 331, and illuminate the symbols on the key 74 in the third language key combination 46 through the second light emitting area configuration 332.

[0031] In summary, the present invention can produce the effect that the shading film 10 can be shared by the first backlit keyboard 12, the second backlit keyboard 14 and the third backlit keyboard 42, thereby effectively solving the problem mentioned in the prior art that the shading films used in backlit keyboards of different languages ​​cannot be shared, thereby greatly reducing the cost of manufacturing the shading films of the backlit keyboards.

[0032] In practical applications, such as Figure 4 as well as Figure 6 As shown, in order to improve the problem that the light emitted by the second backlight module 20 is emitted from the adjacent keycap corners of the keys 48 and 50 in the second language key combination 22, resulting in the keycap corner halo being too bright, as shown in FIG. Figure 4 As shown, the light shielding layer 32 extends from at least one side of the gap between the keycaps of the adjacent keys 48 and 50 toward the light-transmitting pattern 76 to form at least one light shielding block 78 (at Figure 4 Four light shielding blocks 78 are shown in FIG. 1 , and the four light shielding blocks 78 are respectively directed from positions on both sides of the gaps between the key caps of the corresponding adjacent keys 48 and 50 toward the light-transmitting pattern 76 (marked at Figure 6 The light emitted from the corners of the key caps adjacent to the keys 48 and 50 can be properly shielded by the light shielding block 78, thereby effectively solving the problem of too bright halo at the corners of the key caps.

[0033] In summary, the backlit keyboard of the present invention comprises a first language key combination having adjacent first and second keys, a first backlight module and a shading sheet arranged under the first language key combination. The shading sheet is applicable to the backlit keyboard and the second backlit keyboard comprising the second backlight module and the second language key combination, and the positions of the first and second keys on the backlit keyboard coincide with the position of the third key in the second language key combination on the second backlit keyboard. The shading sheet has a first light emitting area configuration corresponding to the first and second keys, and the third key also has a first light emitting area configuration, so as to allow light to illuminate the symbols on the first, second and third keys. In other words, the shading sheet design of the present invention can be applicable to backlit keyboards with two language key combinations, effectively solving the problem that the shading sheets used on backlit keyboards of different languages ​​cannot be shared, thereby greatly reducing the cost of manufacturing the shading sheets of the backlit keyboard.
