Description

 Light-transmitting keycap and manufacturing method thereof  

The present invention relates to a light-transmitting keycap and a method of manufacturing the same, and, in particular, to a light-transmitting keycap suitable for use in a light-emitting keyboard and facilitating the manufacture of a semi-finished product, and a method of manufacturing the same.

Please refer to the Republic of China Patent Bulletin No. I494962 for one of the previous examples of the light-transmitting keycap. Please refer to Figure 1. Fig. 1 is a cross-sectional view schematically showing the structure of a light-transmitting keycap 1 disclosed in the Republic of China Patent Publication No. I494962.

As shown in FIG. 1, the light-transmitting keycap 1 disclosed in the '962 patent includes a light-transmitting body 10, a first color light-transmitting layer 12, a first dark layer 14, a second color light-transmitting layer 16, and a second dark layer. 18.

The first color light transmissive layer 12 is coated on the outer surface 102 of the light transmissive body 10 to cover the first pattern area and does not cover the second pattern area; wherein the first pattern area and the second pattern area respectively represent different characters . The first dark layer 14 is coated on the first color light transmissive layer 12. The second color light transmissive layer 16 is coated on the light transmissive body 10 and the first dark layer 14. The second dark layer 18 is coated on the second color light transmissive layer 16; wherein the first color light transmissive layer 12 and the second color light transmissive layer 16 are different in color. The second dark layer 18 has a first hollow region 182 and a second hollow region 184. The first hollow region 182 extends through the second dark layer 18, the second color light transmissive layer 16, and the first dark layer 14 corresponding to the first pattern region. The second hollow region 184 extends through the second dark layer 18 that covers the second pattern region.

When the light OL travels upward from below the light-transmitting keycap 1, the light passes through the first color light-transmitting layer 12 and the first hollow region 182, causing the first hollow region 182 to present the first color light L1. When the light OL passes through the second color light transmissive layer 16 and the second hollow region 184, the second hollow region 184 is caused to exhibit the second color light L2; thus, different characters on the light-transmitting keycap 1 can emit different colors of light. Thus, the first color light transmissive layer 12 and the second color light transmissive layer 16 are both located below the second dark layer 18, and the different dark areas of the second dark layer 18 correspond to different color light transmissive layers, and different definitions are defined. The character area of the illuminating color.

For another prior art of the light-transmitting keycap, please refer to the Chinese Patent Publication No. 102420065A. The light-transmitting keycap disclosed in the '065 patent publication first coats the first-color light-transmitting layer on the light-transmitting body, and then The two-color light transmissive layer is printed on the first color light transmissive layer, and finally the topcoat layer is coated. That is to say, both the first color light transmissive layer and the second color light transmissive layer are located below the topcoat layer, and different light-emitting layers are defined by different hollow areas of the topcoat layer to define different light-emitting colors. The character area.

However, the color light that can be exhibited on the light-transmitting keycap 1 of the prior art described above is determined by the two light-transmitting layers below the topcoat layer (or the second dark layer 18). Once the topcoat layer (or the second dark layer 18) completes the coating manufacturing process, the two light colors that can be exhibited by the prior art light-transmitting keycaps cannot be changed by subsequent processes. If the customer order revision requires a change in the color of the shade that can be exhibited by the light-emitting keycap, the keycap semi-finished product that has been coated with the topcoat layer can only be discarded according to the prior art.

Therefore, regarding the prior art light-transmitting keycaps, it is not possible to firstly manufacture a semi-finished product in which the topcoat layer has been completed, and then dynamically adjust the subsequent process to manufacture the finished product according to the illuminating color specified by the customer's order, so as to shorten the delivery time. Obviously, the manufacture of prior art light-transmissive keycaps lacks flexibility and convenience.

Therefore, one technical problem to be solved by the present invention is to provide a light-transmitting keycap suitable for a button of an illuminated keyboard and which is advantageous for making a semi-finished product in advance and a method of manufacturing the same.

Layer 26. The light transmissive body 20 has an outer surface 202. The first color light transmissive layer 22 is coated on the outer surface 202 of the light transmissive body 20. The light shielding layer 24 is coated on the first color light transmissive layer 22.

In one embodiment, the first color light transmissive layer 22 may be a light ink layer, for example, a white ink layer, but is not limited thereto. The light shielding layer 24 may be a dark ink layer, for example, a black ink layer, but is not limited thereto.

The light shielding layer 24 has a light shielding region 242 and a first hollow region 244. The first hollow region 244 extends through the light shielding layer 24 to expose a portion of the first color light transmissive layer 22. The second color light transmissive layer 26 is overlaid on the first hollow region 244. It should be emphasized that the function of the second dark layer 18 of the surface of the prior art light-transmitting keycap 1 is the same as that of the light-shielding layer 24 of the surface of the light-transmitting keycap 2 of the present invention. However, the second dark layer 18 of the prior art light-transmitting keycap 1 is coated on the first color light-transmitting layer 12 and the second color light-transmitting layer 16.

In an embodiment, the second color light transmissive layer 26 may be an ink layer having a color depth between the first color light transmissive layer 22 and the light shielding layer 24, for example, a light blue ink layer.

When the light OL travels upward from below the light-transmitting keycap 2, the light OL can pass through the light-transmitting body 20, the first color light-transmitting layer 22, the first hollow region 244, and the second color light-transmitting layer 26, so that the first hollow Region 244 presents a first color light L1. The light shielding layer 24 blocks the passage of the light OL, so that the light shielding region 242 does not emit light. In practical applications, the first hollow area 244 corresponds to the first pattern, and the first pattern represents one of a character, a number, a symbol, and a function key.

The transparent protective layer 27 can also have an ultraviolet-resistant function by the selection of the molding material to prevent the light-transmitting body 20 from being damaged by ultraviolet rays.

Considering that the second color light transmissive layer 26 may have a positional deviation error with respect to the light shielding layer 24 during the manufacturing process, the second color light transmissive layer 26 preferably has the same contour as the first hollow area 244. However, the size is slightly larger than the first hollow area 244. In this way, the probability that the second color light transmissive layer 26 does not completely cover the first hollow region 244 due to the displacement error causes the first hollow region 244 to emit light of different colors.

In one embodiment, as shown in FIGS. 2, 3, and 4, the light shielding layer 24 has an edge region 248 that surrounds the first hollow region 244. The second color light transmissive layer 26 except for completely covering the first hollow region 244, and the second color light transmissive layer 26 portion also extends over the edge region 248. By selecting an appropriate second color light transmissive layer 26 ink, the reflection effect of the second color light transmissive layer 26 on the ambient light is reduced, which can be prevented by the naked eye of the user (1) the second color light transmissive layer 26 The difference between the covered edge region 248 and (2) the light shielding layer 24 other than the edge region 248; that is, when the lower source light OL does not exist, only the upper ambient light illuminates the keycap, the user still only It will be observed that the first hollow region 244 is relatively bright, while the edge region 248 and the remaining light shielding layer 24 are both dark dark regions, so that the perimeter represented by the first hollow region 244 can still be clearly viewed.
