[0029] In order to make the above-mentioned purposes, features and advantages of the backlight keyboard more obvious and easy to understand, the backlight keyboard will be further described in detail below with reference to the drawings and specific embodiments.

[0030] A type of backlit keycap, see Figures 1-2 It includes a one-piece, fully transparent keycap body 100 and a connecting post 200. Specifically, both are injection molded from polycarbonate (PC), and are transparent with good light transmission.

[0031] The keycap body 100 includes a pressing surface 110 and a dustproof wall 120. The top surface of the pressing surface 110 is printed with a non-transparent pattern 130. The dustproof wall 120 surrounds the pressing surface 110 and extends downwards. A connecting post 200 is located directly below the pressing surface 110, and its structure can adopt an existing structure for connection with the keyboard switches. The transition area between the dustproof wall 120 and the connecting post 200 has no additional structure, forming an unobstructed light transmission channel 140.

[0032] By configuring the keycap body 100 and connecting post 200 as a fully transparent structure, and without any additional structure in the transition area between the dustproof wall 120 and the connecting post 200, an unobstructed light transmission channel 140 is formed. This allows the light from the backlight 500 to be transmitted directly and unobstructed upwards along the light transmission channel 140, avoiding the light obstruction and attenuation problems caused by reinforcing ribs in traditional keycaps, and significantly improving the brightness and uniformity of light transmission. By directly printing a non-transparent pattern 130 on the top surface of the pressing surface 110, replacing the two-step processing process of "setting a light-blocking layer + laser engraving a light-transmitting pattern" in the traditional process, the coating process of the light-blocking coating and the investment in laser engraving equipment are eliminated, greatly shortening the production cycle and reducing processing complexity and cost.

[0033] in, Figure 2 The label 140 for the light transmission channel is for illustrative purposes only. The light from the backlight 500 can propagate through this channel, but it is not an actual structure.

[0034] In one embodiment, the non-transparent pattern 130 is a black pattern, which improves the absorption of visible light (especially for RGB backlight), effectively blocks light from penetrating the pattern area, and avoids visual interference caused by the characters being transparent.

[0035] Specifically, the non-transparent pattern 130 is an ink layer formed by screen printing. The ink layer is easy to process and has high processing precision.

[0036] More specifically, the thickness of the ink layer is 0.05-0.15mm. Within this thickness range, the ink layer is designed to completely cover the light-transmitting material below, preventing light leakage and also preventing the ink from being too thick, which would block the lateral light of the light-transmitting channel 140, thus ensuring the brightness of the light transmission.

[0037] In another embodiment, the outer surface of the dustproof wall 120 is provided with a frosted treatment layer, which can significantly reduce the adhesion of fingerprints and stains, improve the light transmission effect, and facilitate cleaning. In the use scenario of the rapid tapping keycap, the frosted texture increases the friction between the finger and the keycap sidewall, preventing slipping during operation.

[0038] In another embodiment, the top surface of the pressing surface 110 is provided with a concave curved surface that fits the natural curvature of the fingertips, disperses the finger pressure during pressing, and reduces fatigue after long-term use.

[0039] Embodiment 2

[0040] A keyboard, as shown in Figures 3-4 , comprises a keyboard body 300, a plurality of shafts (not shown in the figure), a keycap 400, and a backlight 500. The plurality of shafts are arranged on the keyboard body 300, and each shaft is connected with a keycap. The periphery of each shaft is provided with at least one backlight 500 located in the corresponding keycap.

[0041] In this embodiment, the keycap adopts the light-transmitting keycap of Embodiment 1.

[0042] In another embodiment, the periphery of each shaft is provided with one backlight 500, and the backlight 500 is arranged opposite to the non-light-transmitting pattern 130 on the corresponding keycap, which improves the display effect of the non-light-transmitting pattern 130 and makes it easier to clearly see the non-light-transmitting pattern 130.

[0043] In another embodiment, the backlight 500 is arranged on the side of the corresponding shaft away from the user, so that the backlight 500 is hidden behind the keycap. When the user looks straight at the keyboard, there is no direct light source to stimulate the eyes, reducing visual fatigue after long-term use.

[0044] In another embodiment, the shaft bottom is provided with a reflective coating, which reflects the downward light that is not absorbed by the keycap back to the light transmission channel 140, improving the utilization rate of light transmission and reducing the power consumption demand of the backlight 500. The reflected light fills the illumination dead angle at the bottom edge of the keycap, solving the problem of insufficient brightness at the bottom of the keycap in traditional keyboards.

[0045] It should be noted that, Figure 4 The connecting column 200, the non-light-transmitting pattern 130, and the backlight 500 of the keycap body 100 are only schematic diagrams, mainly to show the positional relationship of the three.

[0046] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and also impossible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application claims.
