Light-transmitting button, light-transmitting keycap and manufacturing method of light-transmitting keycap

The present invention relates to a keyboard accessory and a method of manufacturing the same, and more particularly to a method for manufacturing a light-transmitting button, a light-transmitting keycap, and a light-transmitting keycap for an illuminated keyboard.

Due to the gradual popularization of the illuminated keyboard, the functional requirements of the user for the illuminated keyboard are becoming stricter. Please refer to FIG. 1a and FIG. 1b, which are schematic diagrams of main layers of a conventional illuminated keyboard. As shown in FIG. 1a, the conventional illuminated keyboard includes a button set, a metal backplane layer 25, a light shielding layer 23, a light guide layer 22, a backlight 24, and a reflector layer 26 from top to bottom. The button group has a plurality of buttons 21, and the light-emitting key cap 211 on the button 21 is in a backlight environment by the illumination of the backlight 24, the light guide of the light guide plate layer 22, and the reflection of the reflector layer 26. The identification pattern of the light-transmitting keycap 211 can be illuminated, and the user can identify the type of each button 21 by light in a dim environment.

In general, as shown in FIG. 1a, when the backlight 24 inside the keyboard is turned on to provide the backlight illustrated by the arrow line of FIG. 1a to the light-transmitting keycap 211, the hollow pattern 2111 on the light-transmitting keycap 211 is illuminated. Brighter. As shown in FIG. 1b, when the backlight 24 inside the keyboard is turned off and the output backlight is stopped, there is still enough light to pass through the keycap shielding layer by the external ambient light illuminating by the arrow line of FIG. 1b. The upper hollow pattern 2111 is reflected by the keycap primer 2113, and then is exposed from the hollow pattern 2111 to be observed by the user, so that the hollow pattern 2111 of the keycap shielding layer and the surface gloss of the shielding area 2112 are visually There are significant differences. Therefore, regardless of whether the backlight 24 inside the keyboard is turned on or off, even if the brightness may be different, the user can observe the identification pattern on the light-transmitting keycap.

But with the diversification of computer, smart phone, and tablet operating systems, Ex: Microsoft, iOS, Android, therefore, there are users who have requested that they can selectively switch through the wireless Bluetooth interface of a single illuminated keyboard. To input text with the electronic products of different operating systems, but the special function key symbols of each operating system should be concealed when they are not used, indicating that they cannot function. For example, when the keyboard is connected to the PC of the Microsoft operating system, the function key symbols of the iOS operating system are hidden and not illuminated, making it difficult to observe. However, when the keyboard is connected to the iPad of the iOS operating system, the function key symbols of the iOS operating system are illuminated and made easy for the user to observe.

Therefore, how to display or hide the identification pattern on the transparent keycap by timely turning on or off the backlight inside the keyboard; for example, when the backlight is turned on, the identification pattern on the transparent keycap is bright and easy to be It is observed that when the backlight is turned off, the identification pattern on the light-transmissive keycap is hidden and not obvious, which is a technical issue that the industry is currently paying attention to.

In view of the above-mentioned disadvantages of the prior art, the present invention provides a light-transmitting keycap that can be used in a backlight environment of an illuminated keyboard, including a transparent keycap body, a shielding layer, and a translucent layer. The shielding layer is disposed on the outer surface of the transparent keycap body and includes a hollow portion, and the hollow portion has a hollow pattern showing a shape of a character symbol. The translucent layer is disposed on the shielding layer and covers the hollow portion. The translucent layer has a light transmittance of 20% to 80% under the irradiation of visible light, and has a color similar to the shielding layer, and can be achieved in a backlight-free environment. The effect of concealing the hollow.

Alternatively, the light transmissive keycap of the present invention comprises a light transmissive protective layer made of a colorless UV lacquer material to provide skin protection as the outermost layer of the keycap.

Optionally, the light-transmitting keycap of the present invention comprises a light-transmitting primer layer disposed between the outer surface of the transparent keycap body and the shielding layer. Moreover, the shielding layer includes a first hollow portion and a second hollow portion, and the first and second hollow portions have a hollow pattern that exhibits a symbol shape of a character. The translucent layer is disposed on the shielding layer to cover at least the first hollow portion but does not cover the second hollow portion. The translucent layer achieves the effect of concealing the first hollow in a non-backlit environment.

In addition, the present invention provides a light-transmitting keycap that operates in an environment that provides an ambient light, a backlight below, a backlight that can be selectively extinguished, or illuminates to emit visible light, including a transparent keycap body, and a shadow. Layer and translucent layer. The surface of the transparent keycap body can be divided into a first area and a second area. The shielding layer is disposed on the outer surface of the transparent keycap body, and the shielding layer has a hollow portion and a shielding portion. The hollow portion exposes a first region of the surface of the transparent keycap body, and the shielding portion covers the second region of the surface of the transparent keycap body. The translucent layer is disposed on the shielding layer and covers at least the hollow portion. The translucent layer has a light transmittance of 20% to 80% for visible light and has a color similar to the shielding layer. When the backlight is lit, the visible light can be respectively transmitted to the hollow portion and the shielding portion, so that the visible light enters the hollow portion and partially penetrates the translucent layer to conduct outward, but the visible light cannot penetrate the shielding portion, so that the key cap body only The illumination of a region enhances the visual difference between the first region and the shielding portion, and helps the user to distinguish the hollow portion from the shielding portion. When the backlight is extinguished and there is no visible light, even if the external ambient light partially penetrates the translucent layer and enters the hollow portion, since the light transmittance of the translucent layer is low, the external ambient light intensity is attenuated by the translucent layer, and the translucent layer Similar to the color of the shielding layer, the light or white color of the transparent keycap body is filtered by the translucent layer to change to a dark color; thus, the keycap is observed under the condition of only ambient light, due to the light transmittance of the translucent layer. With the influence of color, the visual difference between the first area and the shielding part is limited, so that the user cannot easily distinguish the hollow part from the shielding part, and the effect of concealing the hollow part is achieved.

Alternatively, the shielding layer has a first hollow portion, a second hollow portion and a shielding portion. The first and second hollow portions respectively expose the first and second regions. The shielding portion covers the third region. The translucent layer is disposed on the shielding layer to cover at least the first hollow portion but does not cover the second hollow portion. When the backlight is lit, the visible light can be respectively transmitted to the first and second hollow portions and the shielding portion, so that the visible light enters the first hollow portion and partially penetrates the translucent layer to be exposed, and the visible light enters the second hollow portion. And revealing outward, but the visible light can not penetrate the shielding portion, so that the transparent key cap body only emits light in the first and second regions, which improves the visual difference between the first region and the second region relative to the shielding portion, and helps the user to distinguish The first area, the second area, and the shielding portion. When the backlight is extinguished without visible light, the external ambient light may illuminate the first region and the second region. Due to the low transmittance of the translucent layer, the ambient light intensity is attenuated by the translucent layer, and the translucent layer and the shielding layer The color is similar, the light color or white of the transparent key cap body is filtered by the translucent layer to change into a dark color; thus, the key cap is observed under the condition of only the external ambient light, and the first area and the shadow are obscured by the translucent layer. The visual difference between the two is limited, and the user cannot easily distinguish the first hollow portion from the shielding portion, so as to achieve the effect of concealing the first hollow portion. At the same time, the external ambient light also enters the second hollow, because the ambient light intensity is not attenuated by the translucent layer, and the light or white color of the transparent key cap body is not filtered by the translucent layer to change to a dark color, so The second region and the shielding portion can be distinguished, so that the shielding layer is observed under the external ambient light, and the visual difference between the second hollow portion and the shielding portion is obvious, and the user can easily distinguish the second hollow portion from the shielding portion.

The invention provides a method for manufacturing a light-transmitting keycap, comprising the steps of: providing a transparent keycap body; coating a transparent light-transmitting primer layer on the outer surface of the transparent keycap body; The lacquer layer is covered with a shielding layer; a hollow portion having a hollow pattern is formed on the shielding layer; and the shielding layer is covered with a translucent layer having a light transmittance of 20% to 80% under the irradiation of visible light, and is translucent The layer covers the hollow. The material of the translucent layer needs to be pre-toned to have a color similar to that of the masking layer.

Alternatively, if the material is a light or white transparent key cap body, the step of coating the light transmissive primer layer may be omitted, and the outer surface of the transparent key cap body is directly covered with a shielding layer. A first hollow portion having a hollow pattern and a second hollow portion are formed in the shielding layer. Next, the translucent layer is covered on the first hollow portion.

Alternatively, after the translucent layer is covered with the shielding layer, the translucent protective layer is coated on the translucent layer. The masking layer can optionally be formed by painting, printing, in-mold transfer (IMR) or over-mold transfer (OMR) techniques. The hollow pattern of the obscured layer hollow portion is formed by the technique of general ray carving or micro-hole ray carving.

Furthermore, the present invention also provides a light transmissive button comprising a transparent keycap body, a backlight, a shielding layer, and a translucent layer. The backlight is disposed under the transparent keycap body. The backlight can be selectively extinguished or illuminated to emit a visible light.

Optionally, the light-transmitting button of the present invention is electrically connected to the computer system, wherein the hollow pattern of the first hollow portion corresponds to the first language input method, and the hollow pattern of the second hollow portion corresponds to the second language input method. When the computer system starts the first language input method, the backlight is lit. When the computer system activates the second language input method, the backlight is turned off.

Optionally, the light-transmitting button of the present invention is electrically and electrically connected to one of a plurality of computer systems, wherein the hollow pattern of the first hollow portion corresponds to the first operating system, and the hollow pattern of the second hollow portion Corresponds to the second operating system. The backlight illuminates when the connected computer system executes the first operating system. When the connected computer system executes the second operating system, the backlight is turned off.

Compared with the prior art, the light-transmitting keycap of the present invention conceals the hollow portion on the shielding layer in a non-backlight environment by a translucent layer similar to the color of the shielding layer. In addition, the light-transmitting keycap of the present invention can select only the semi-transparent layer to cover a part of the hollow portion, and in the non-backlight environment, only a part of the hollow portion is concealed on the shielding layer, and other hollow portions not covered with the translucent layer are still Under the influence of external ambient light, there is a clear visual difference with the shielding portion of the shielding layer, which helps the user to recognize both.

The other aspects of the present invention will be readily understood by those skilled in the art from this disclosure. The invention may also be embodied or applied by other different embodiments. The details of the present invention can be variously modified and changed without departing from the spirit and scope of the invention. In particular, the relative relationship and relative positions of the various elements in the drawings are for illustrative purposes only and are not representative of actual implementation of the invention.

The illuminated keyboard sometimes switches the operation mode during use. Due to the user's request, when the operation mode is switched, it is desirable that the identification pattern corresponding to the operation mode on the light-transmitting keycap of the light-transmitting button can be clearly displayed, and the operation mode Unrelated identification patterns can be unclear or even hidden. For example, when the illuminated keyboard is in the lowercase input mode of the English alphabet, if the light-emitting button "CapsLk" is used to indicate that the recognition pattern of the CapsLk can be blurred, it will help the user understand the current illuminated keyboard. The keystrokes are in the lowercase input mode of the English alphabet. Similarly, when the illuminated keyboard is in the uppercase input mode of the English alphabet, it is hoped that the light-receiving button "CapsLk" is used to indicate that the recognition pattern of the CapsLk can be clearly displayed.

However, the light-transmitting keycap of the light-transmitting button is sometimes affected by the external ambient light, and the recognition pattern on the light-transmissive button cannot be in a fuzzy display state, in order to reduce the influence of the external ambient light on the light-transmitting keycap of the light-transmitting button, The present invention provides an improved light transmissive button, a light transmissive keycap, and a method of manufacturing a light transmissive keycap. The light-emitting keycap of the present invention can be used in a backlight environment caused by visible light emitted by a backlight below the interior of the illuminated keyboard.

Referring to FIG. 2 and FIG. 3 , the light-transmissive key caps in the same state of the present invention are in a backlight environment and are not in a backlight environment but are affected by external ambient light. As shown in FIG. 2, when the light-transmitting keycap 12 is in a backlight environment, the user can clearly recognize the hollow pattern on the light-transmitting keycap for representing the character symbol "A" by the backlight of the light-transmitting keycap. As shown in FIG. 3, when the light-transmitting keycap is not in the backlight environment, the hollow pattern on the light-transmitting keycap to indicate the character symbol "A" cannot be clearly recognized.

Please also refer to FIG. 12 and FIG. 13 , which are schematic diagrams of another embodiment of the present invention in which the light-transmitting keycap is in a backlight environment and is not in a backlight environment but is affected by ambient light. As shown in FIG. 12, when the computer system is in the English input method, the light-transmitting keycap is in a backlight environment, and the user can clearly recognize the word on the light-transmissive keycap of the light-transmitting key by using the backlight of the light-transmitting keycap. Two hollow patterns of the meta-symbols "D" and "ㄎ". As shown in FIG. 13, when the computer system is in the Chinese input method, the light-transmitting keycap is not in the backlight environment, and the hollow pattern on the light-transmitting keycap for indicating the character symbol "D" cannot be clearly recognized, but is used to indicate The cutout pattern of the character symbol "ㄎ" can still be clearly identified. It should be noted that, in FIG. 12 and FIG. 13 , a single light-transmissive key cap of a Chinese keyboard that is simultaneously provided with "D" and "ㄎ" character symbols is taken as an example for convenience of illustration and not limitation. And when the computer system switches different input methods to start different input characters, the transparent keycap of the backlit keyboard of the present invention can adapt to the collocation operation, changing the display manner of the hollow pattern representing the character symbol; but the actual practice of the present invention The implementation is not limited to the input method switching context, but also applies to the KVM switching keyboard when connected to different operating system computers, the keyboard changes to display the currently available quick keys or function keys.

Therefore, the light-transmitting button and the light-transmitting keycap of the present invention can be designed, and in the backlight environment and in the backlight environment, the hollow pattern for the shielding layer has different representation manners to conform to various light-transmitting keys and light-transmitting keys. The actual needs of the cap.

In the following embodiments, the same or similar elements are denoted by the same reference numerals, and the same or similar technical features will be omitted from the description of the present invention.

First embodiment

The light-transmissive keycap of the present embodiment operates in an environment that provides an ambient light, and has a backlight underneath, the backlight can be selectively extinguished, or a visible light is emitted. According to FIG. 4 and FIG. 6a to FIG. 6e of the present invention, the light-transmitting keycap of the present embodiment has a transparent keycap body 11, a shielding layer 12, and a translucent layer 13. The surface of the transparent keycap body 11 can be divided into a first area and a second area. The shielding layer 12 is disposed on the transparent keycap body 11 and has a hollow portion 121 and a shielding portion 122. The hollow portion 121 has a hollow pattern in the shape of a character symbol, and the first region of the transparent keycap body 11 can be exposed in an operating environment, and the backlight of the backlight can be sequentially conducted upward through the transparent keycap body 11 and the hollow portion 121, and The hollow pattern of the hollow portion 121 is highlighted. The shielding portion 122 can provide light shielding to the second region of the transparent keycap body 11 to prevent the backlight of the backlight from being transmitted from the second region of the transparent keycap body 11 to the outside, so that the hollow portion and the shielding portion are conspicuous The difference between light and dark, to highlight the bright display of the hollow. The translucent layer 13 is at least covered on the hollow portion 121 of the shielding layer 12, and the translucent layer 13 has a light transmittance of 20% to 80% under the irradiation of visible light, and has a color similar to that of the shielding layer 12.

More specifically, when the backlight under the illumination keyboard is illuminated, the visible light emitted by the backlight can be respectively transmitted to the hollow portion and the shielding portion, and the visible light transmitted to the hollow portion 121 can partially penetrate the translucent layer 13 and It is disclosed that the visible light transmitted to the shielding portion 122 cannot penetrate the shielding portion, so that only the hollow pattern of the hollow portion 121 emits light, and the user can identify the hollow portion on the light-transmitting keycap to indicate the hollow shape of the character symbol. pattern.

When the backlight 24 is extinguished, the external ambient light can be conducted to the hollow portion 121, so that the external ambient light partially penetrates the translucent layer 13 and enters the hollow portion 121, and the transparency is reduced due to the light transmittance and color of the translucent layer 13. The visual difference between the first region of the keycap body 11 and the shielding portion under external ambient light prevents the user from distinguishing the first region of the transparent keycap body 11 from the shielding portion under external ambient light, thereby observing the keycap shielding under external ambient light. The layer 12 does not easily recognize the difference between the hollow portion 121 and the shielding portion 122, and the effect of concealing the hollow portion 121 is achieved.

Referring to FIG. 5 and FIG. 6a to FIG. 6e, a manufacturing flow of the light-transmitting keycap of the present embodiment is illustrated. First, in step S1 of Fig. 5, a transparent keycap body 11 as shown in Fig. 6a is first provided. Then, in step S2 of FIG. 5, the transparent keycap body 11 is covered with a shielding layer 12 as shown in FIG. 6b, and the shielding layer 12 is selectively permeable to paint, printing, in-mold transfer (IMR) or over-molding. Transfer (OMR) technology is formed on the transparent keycap body 11. Next, a hollow portion 121 having a hollow pattern as shown in FIG. 6c is formed on the shielding layer 12 (ie, step S3 of FIG. 5). It should be noted that the hollow pattern of the hollow portion 121 can be formed by a process technique of general ray carving or micro-hole ray carving, and a plurality of ray-shaped holes are arranged to form a hollow pattern to form a hollow portion 121, thereby forming a ray sculpture. The wall surface of the hole blocks part of the external ambient light in the conduction direction from entering the hollow portion 121, thereby reducing the extent to which the external ambient light enters the hollow portion 121, thereby providing the effect of concealing the hollow portion.

Then, in step S4 of FIG. 5, the shielding layer 12 is covered with a translucent layer 13 as shown in FIG. 6d and FIG. 6e, and the translucent layer 13 needs to cover at least the hollow portion 121 of the shielding layer 12, The semi-transparent layer has a lower transmittance, attenuating the intensity of the visible light of the external environment penetrating into the hollow portion 121 of the shielding layer 12 to reduce the light or white reflected light intensity of the keycap body 11, and the material of the translucent layer 13 is required. Pre-coloring, making the color similar to the dark masking layer 12, so that the light or white reflected light of the keycap body 11 is filtered by the translucent layer to change into a dark color, both of which contribute to the dark color. The hollow portion 121 is concealed on the shielding layer 12, so that the hollow portion 121 of the light-transmitting keycap not in the backlight environment is not easily recognized on the shielding layer 12. On the other hand, if the color of the translucent layer is selected to be white (i.e., light color) having a large difference in color from the black (i.e., dark) masking layer, the white reflection from the hollow portion 121 under the translucent layer 13 is observed under the external ambient light. Although the light is relatively weak and dim, the high contrast difference between the white hollow portion 121 and the black shielding portion 122 is still easily observed by the naked eye.

It should be noted that, when the translucent layer 13 is formed, there may be a situation in which the solidification of the translucent layer 13 is too fast to be leveled, so that the semi-transparent layer 13 has a concave outer surface corresponding to the position of the hollow portion 121 of the shielding layer 12 (such as Fig. 6e), but the translucent layer 13 does not affect the brightness of the ambient light that penetrates into the hollow portion 121 even if it has a concave outer surface.

Second embodiment

According to the figures 2 to 3 and 7a of the present invention, the light transmissive keycap may further be provided with a light transmissive primer layer 15 which is disposed between the outer surface of the transparent keycap body 11 and the shielding layer 12. . The light transmissive primer layer 15 is selected to have a paint of a specific color, and the color of the backlight that is transmitted from the transparent keycap body 11 to the shielding layer 12 can meet the demand. In other words, when the backlight is lit to cause the first region of the transparent keycap body 11 to emit light, the transparent primer layer 15 can change the color of the first region of the transparent keycap body 11. The shielding layer 12 is disposed on the light transmissive primer layer 15 , and the shielding layer 12 has a hollow portion 121 and a shielding portion 122 . The hollow portion 121 has a hollowed out pattern to expose the first region of the transparent keycap body 11 in an operating environment. The backlight transmitted to the transparent keycap body 11 can be conducted outward through the first region of the transparent keycap body 11 and the hollow portion 121 in sequence. The shielding portion 122 can provide light shielding to the second region of the transparent keycap body 11 to prevent the backlight of the backlight from being transmitted from the second region of the transparent keycap body 11 to the outside, so that the hollow portion 121 and the shielding portion 122 are distinct. The difference between light and dark, to highlight the bright display of the hollow pattern. The translucent layer 13 has a light transmittance of 20% to 80% for visible light and has a color similar to that of the shielding layer 12. The translucent layer 13 can be made of a paint that is not a UV paint, such as a PU paint or an acrylic paint.

Referring to FIG. 7b, when the backlight inside the keyboard is turned on and the backlight illustrated in the arrow line of FIG. 7b is provided to the light-transmitting keycap, the hollow portion 121 on the light-transmitting keycap emits light, and the shielding portion 122 is brighter. The hollow pattern indicated by the hollow portion 121 can be clearly identified. Referring to FIG. 7c, when the backlight is extinguished without emitting visible light, if the hollow pattern is to be observed by the user, the ambient light exemplified by the arrow line of FIG. 7c needs to penetrate the translucent layer 13 first. The hollow portion 121 is then reflected by the light transmissive primer layer 15 and finally penetrates the translucent layer 13 upward again into the user's eyes.

The brightness of the external ambient light is greatly attenuated after passing through the translucent layer 13 twice, and the brightness of the hollow portion of the transparent keycap observed by the user is greatly reduced, so that the hollow portion is exposed to the external ambient light without backlight. The gloss is dark when affected, and since the color of the translucent layer is close to that of the shielding layer, there is no contrast of high contrast. Thus, when the shielding layer is observed under external ambient light, the difference between the hollow portion and the shielding portion cannot be easily recognized. , 俾 achieves the concealing effect of the hollow portion 121 shown in FIG. The arrow line of the dotted line in Fig. 7c indicates that the brightness of the ambient light outside the hollow portion of the light-transmitting keycap is attenuated and filtered by the dark translucent layer 13, so that the brightness of the hollow portion of the light-transmitting keycap can be observed. Significantly reduce darkening and turn dark, so you can achieve the effect of reaching a hidden hollow in a non-backlit environment.

Referring to FIG. 8 and FIG. 9a to FIG. 9f together, a manufacturing flow of the light-transmitting keycap of the present embodiment will be exemplified. First, in step S1' of Fig. 8, a transparent keycap body 11 as shown in Fig. 9a is first provided. Then, in step S2' of FIG. 8, the transparent keycap body 11 is covered with a light transmissive primer layer 15 as shown in FIG. 9b, and the light transmissive primer layer 15 is formed by transparent coating or the like. On the key cap body 11. The light transmissive primer layer 15 generally has a light transmittance of 20% to 80%, and the light transmissive primer layer 15 has two purposes: one, providing light diffusibility to uniformly astigmatize, and uniformizing light transmitted through the hollow portion; Second, when the backlight is not lit, the hollow portion can be clearly recognized only when the light-transmitting primer layer 15 reflects ambient light. However, in the actual product application, the light-transmitting primer layer 15 can also be omitted, and the above two effects can also be achieved by changing the color of the transparent keycap body 11 material. In step S3' of FIG. 8, a masking layer 12 as shown in FIG. 9c is formed on the light transmissive primer layer 15 by painting, printing, in-mold transfer (IMR) or over-mold transfer (OMR) techniques, and then A hollow portion 121 having a hollow pattern as shown in FIG. 9d is formed on the shielding layer 12 (ie, step S4' of FIG. 8). It should be noted that the hollow pattern of the hollow portion can be formed by a process technique of general ray carving or micro-hole ray carving, and a plurality of ray-shaped holes are arranged to form a hollow pattern to form a hollow portion 121, thereby forming a ray hole. The outer surface light of the wall shielding portion in the conduction direction enters the hollow portion 121, whereby the extent to which the external ambient light enters the hollow portion 121 is reduced.

Then, in step S5' of Fig. 8, the shielding layer 12 is covered with the translucent layer 13 as shown in Figs. 9e and 9f. The translucent layer 13 needs to cover at least the hollow portion 121 of the shielding layer 12 to attenuate the brightness of the external ambient light entering the hollow portion 121 of the shielding layer 12, and the material of the translucent layer 13 needs to be pre-toned to have a shielding layer. 12 similar colors, so that the hollow portion 121 of the light-transmitting keycap not in the backlight environment is not easily recognized.

It should be noted that, when the translucent layer 13 is formed, there may be a situation in which the forming and curing are too fast to be leveled, and the outer surface of the translucent layer 13 is recessed corresponding to the position of the hollow portion 121 of the shielding layer 12 (as shown in the figure). 9f), but the translucent layer 13 does not affect the brightness of the ambient light which can attenuate the hollow portion 121 even if it is formed with a depression.

Third embodiment

According to FIG. 10 of the present invention, the light-transmitting keycap can also be provided with a light-transmissive protective layer 14 on the translucent layer 13 to provide surface protection as the outermost layer of the keycap. In general, the light transmissive protective layer 14 is selected to be made of a colorless UV Curing Paint material to provide surface protection by utilizing the high hardness, abrasion resistance, and chemical resistance of the UV paint. In principle, the light-transmitting protective layer 14 has light transmissivity without excessively attenuating the intensity of the external ambient light, but actually the light transmittance of the light-transmitting protective layer can be appropriately adjusted, ranging from 50% (matte type) to 90 The light transmittance between % (transparent highlights) is common.

Fourth embodiment

According to FIG. 11 of the present invention, the light-transmitting keycap can also be provided with the light-transmissive protective layer 14 and the light-transmitting primer layer 15 at the same time. The transparent protective layer 14 is disposed on the outermost layer above the semi-transparent layer 13 to provide surface protection, and the transparent primer layer 15 is disposed between the transparent keycap body 11 and the shielding layer 12, thereby changing the transparency. The color of the backlight that the keycap body 11 conducts toward the shielding layer 12 makes the color of the backlight revealed by the hollow portion 121 meet the demand.

Fifth embodiment

According to Figs. 12 to 14a of the present invention, the outer surface of the transparent keycap body 11 is provided with a light transmissive primer layer 15. The light transmissive primer layer 15 is selected to have a paint of a specific color, and the color of the backlight that is transmitted from the transparent keycap body 11 to the shielding layer 12 can meet the demand. The shielding layer 12 is disposed on the transparent primer layer 15. The shielding layer 12 has a first hollow portion 121a, a second hollow portion 121b and a shielding portion 122. The first and second hollow portions respectively have an associated hollow pattern, The transparent primer layer 15 is exposed in the operating environment, so that the backlight of the transparent keycap body 11 can be directly exposed through the transparent primer layer 15 and the first hollow portion 121a, and can also be sequentially passed through. The light primer layer 15 and the second hollow portion 121b are exposed to the outside. The translucent layer 13 has a light transmittance of 20% to 80% for visible light and has a color similar to that of the shielding layer 12. The translucent layer 13 can be made of a paint which is not a UV paint, and the selected paint is, for example, a PU paint or an acrylic paint.

Referring to FIG. 14b, when the backlight inside the keyboard is turned on and the backlight illustrated in FIG. 14b is provided to the light-transmitting keycap, the first and second hollow portions 121a and 121b on the light-transmitting keycap will be The light is transmitted, and the shielding portion 122 is brighter, so that the hollow patterns indicated by the first and second hollow portions 121a and 121b can be clearly recognized. Referring to FIG. 14c, when the backlight is extinguished without emitting visible light, the ambient light exemplified by the arrow line of FIG. 14c passes through the transparent protective layer 14, and the external ambient light passes through a portion of the transparent protective layer 14. The first hollow portion 121a is entered in the translucent layer 13, and the other portion enters the second hollow portion 121b in the light-transmitting protective layer 14.

The ambient light enters the first hollow portion 121a and is reflected by the light transmissive primer layer 15, and finally penetrates the translucent layer 13 upward again into the user's eyes. The brightness of the external ambient light is greatly attenuated after passing through the translucent layer 13 twice to reduce the light or white reflected light intensity of the light transmissive primer layer 15, and the hollowed out key cap of the user is observed. The brightness of the part is greatly reduced. The material of the translucent layer 13 needs to be pre-toned to have a color similar to that of the dark masking layer 12, so that the light or white reflected light of the light-transmitting primer layer 15 is filtered by the translucent layer 13 to be changed to a dark color. The first hollow portion 121a is made dark when the backlight is not affected by the external ambient light, and since the translucent layer is close to the color of the shielding layer, the shielding layer is observed under the external ambient light, and the first hollow portion 121a and the shielding portion are shielded. The difference between the two parts cannot be easily recognized, and the concealing effect of the first hollow portion 121a shown in Fig. 13 is achieved. On the other hand, if the color of the translucent layer is selected to be a light color having a large difference from the color of the shielding layer, the light reflected by the first hollow portion 121a under the semi-transparent layer 13 is weak and dim, although it is observed under the external ambient light. The higher contrast difference between the light first first hollow portion 121a and the dark shade portion 122 is still easily observed by the naked eye. The arrow line of the dotted line in Fig. 14c indicates that the brightness of the ambient light outside the hollow portion of the light-transmissive keycap is attenuated and filtered by the effect of the translucent layer 13, so that the first hollow portion 121a of the light-transmitting keycap can be observed. The brightness will be greatly reduced and darkened and turned into a dark color, which both contribute to concealing the first hollow portion 121a.

After the ambient light enters the second hollow portion 121b, it is reflected by the light-transmitting primer layer 15, and finally passes upward through the light-transmitting protective layer 14 to enter the user's eyes. Since the light-transmissive protective layer 14 has no color, the user can observe the second hollow portion 121b of the light-transmitting keycap via the external ambient light reflected by the light-transmitting primer layer 15, and thus, the second hollow portion 121b and the shielding portion 12 The visual difference in color brightness between the two can be easily recognized, and the highlight effect of the second hollow portion 121b shown in Fig. 13 is achieved. When the shielding layer 12 is observed under the external ambient light, the visual difference in color brightness between the first hollow portion 121a and the shielding portion 12 is small, and the color difference between the second hollow portion 121b and the shielding portion 12 is visually different. Therefore, it is difficult for the user to recognize the hollow pattern of the first hollow portion 121a, but the user can still easily recognize the hollow pattern of the second hollow portion 121b.

Accordingly, when the light-transmitting keycap of the embodiment is not in the backlight environment, receiving the external ambient light can make the hollow portion of the different positions on the shielding layer have a different presentation manner, thereby making the light-transmissive keycap hollow pattern diversified. Present the effect and meet the demand.

Referring to FIG. 15 and FIG. 16a to FIG. 16h together, the manufacturing flow of the light-transmitting keycap of the present embodiment will be exemplified. First, in the step S1" of Fig. 15, the transparent keycap body 11 as shown in Fig. 16a is first provided. Then, in the step S2" of Fig. 15, the transparent keycap body 11 is overlaid as shown in Fig. 16b. The light transmissive primer layer 15 and the light transmissive primer layer 15 are formed on the transparent keycap body 11 by painting or the like. The light transmissive primer layer 15 generally has a light transmittance of 20% to 80%, and the light transmissive primer layer 15 has two purposes: one, providing light diffusibility to uniformly astigmatize, and uniformizing light transmitted through the hollow portion; Second, when the backlight is not lit, the hollow portion can be clearly recognized only when the light-transmitting primer layer 15 reflects ambient light. However, in the actual product application, the light-transmitting primer layer 15 can also be omitted, and the above two effects can also be achieved by changing the color of the transparent keycap body 11 material. In step S3' of FIG. 15, a masking layer 12 as shown in FIG. 16c is formed on the light-transmitting primer layer 15 by painting, printing, in-mold transfer (IMR) or over-mold transfer (OMR) techniques, and then The first and second hollow portions 121a, 121b having a hollow pattern as shown in Fig. 16d are formed on the shielding layer 12 (i.e., step S4' of Fig. 15). It should be noted that the hollow pattern of the first and second hollow portions may be formed by a process technique of general ray carving or micro-hole ray carving; if the plurality of ray-shaped holes are arranged to form a hollow pattern, the first and the first forms are formed. The two hollow portions 121a and 121b are formed by blocking the external ambient light in the conduction direction of the wall surface of the Ray-cut hole, thereby further reducing the extent to which the external ambient light enters the first and second hollow portions.

Then, in step S5" of Fig. 15, the shielding layer 12 is covered with a translucent layer 13 as shown in Figs. 16e and 16f. The translucent layer 13 is provided on the shielding layer 12, and the material needs to be pre-adjusted. The color has a color similar to that of the shielding layer 12, covering at least the first hollow portion 121a of the shielding layer 12, but not covering the second hollow portion 121b. For example, the first hollow portion 121a is located on the left upper surface of the keycap. The second hollow portion 121b is located on the right upper surface of the key cap; the pad printing process can be used to cover the preset area of the left upper surface of the keycap by the translucent layer 13 (Fig. 12, Fig. 13 left) The square rectangular dotted line area, but the right half upper surface of the retaining cap is not covered by the translucent layer 13. Thus, the translucent layer 13 only attenuates and affects the brightness and color of the external ambient light received by the first hollow portion 121a. And providing concealment to the first hollow portion 121a.

It should be noted that, when the semi-transparent layer 13 is formed, there may be a situation in which the solidification of the translucent layer is too fast to be leveled, and the outer surface of the translucent layer 13 is recessed corresponding to the position of the first hollow portion 121a (see FIG. 16f). However, the outer surface of the translucent layer 13 does not affect the effect of attenuating the brightness of the external ambient light even if a depression is formed.

In step S6" of Fig. 15, the translucent protective layer 14 as shown in Figs. 16g and 16h is covered on the translucent layer 13 and the second hollow portion 121b to provide surface protection as the outermost layer of the keycap. The light-transmissive protective layer 14 is generally selected to be made of a colorless UV varnish (Ultraviolet Curing Paint) material to provide surface protection by utilizing the high hardness, abrasion resistance, and chemical resistance of the UV lacquer. The light transmissive protective layer 14 has light transmissivity without excessively attenuating the intensity of the external ambient light. However, the light transmittance of the transparent protective layer can be adjusted according to the actual mode, ranging from 50% (matte type) to 90%. The light transmittance between (transparent highlight type) is common. With the translucent layer 13 covered by step S5", when the backlight is not lit, only the second hollow portion 121b of the keycap is easily recognized by the user. However, the first hollow portion 121a is not easily recognized by the user. The light transmissive protective layer 14 can also be omitted for practical product applications.

It should be noted that the forming and curing process of the light-transmissive protective layer 14 includes a "leveling" process, so that the light-transmissive protective layer 14 is leveled to compensate "there is no translucent layer 13 on the left side" and "there is an extra translucent layer on the right side" The height difference between the 13 regions is extremely small, and the thickness of the translucent layer 13 is extremely small; therefore, the upper surface of the entire light-transmissive protective layer 14 is still relatively flat for use; but it may be too flat to form because the forming cures too fast. In a situation, the outer surface of the transparent protective layer 14 is formed with a recess corresponding to the position of the second hollow portion (as shown in FIG. 16h), but the outer surface of the transparent protective layer 14 does not affect the penetration even if it is formed with a recess. The physical properties of light.

It should be noted that the present invention further provides a light-transmitting button, comprising a backlight, and the transparent key cap body, the shielding layer and the translucent layer described in the above embodiments. The backlight is disposed under the transparent keycap body. The backlight can be selectively extinguished or illuminated to emit a visible light.

In summary, at least a part of the hollow portion of the light-transmitting keycap shielding layer of the present invention is covered with a translucent layer that is not completely transparent, and the translucent layer has a brightness that can attenuate the ambient light and is similar to the color of the shielding layer. The material characteristics, so that the hollow portion covered by the translucent layer is affected by the external ambient light, thereby providing concealment to the covered hollow portion in the absence of a backlight environment. The light-transmitting keycap shielding layer of the invention may also be selected, and the hollow portion not covering the translucent layer covers the light-transmissive protective layer which can be completely transparent, and the light-transmitting protective layer can provide surface protection, and can also provide a transparent protective layer. The light-transmissive material properties allow the covered hollow to be exposed to external ambient light and clearly present in a non-backlit environment.

Modifications and variations of the above-described embodiments can be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, the scope of the invention should be as defined in the scope of the invention.
