The core innovation of the GAOXD “Prism” keycap lies in its use of dual-material (ABS+PC) injection molding and a unique “break-form” top geometry. This design reconciles two previously mutually exclusive requirements: top-surface legend illumination and full-keycap translucency. Departing from the conventional approach—where an opaque shell features cutouts for legends—the Prism design extends the transparent PC component from the legends all the way to the base, creating an L-shaped light path. The legends are positioned toward the bottom, aligning perfectly with the south-facing LED orientation common in today’s mainstream mechanical keyboards, while the frosted PC surface at the top diffuses point-source light into a soft, uniform glow. Developed through a collaboration between GAOXD, Titan Kingdom (Titan Nation), and XVX, this design offers a structurally distinct option within the 2026 landscape of shine-through keycaps.
I. The Dilemma of Shine-Through Keycaps and the “Prism” Solution
As of 2026, shine-through keycaps occupy an awkward position in the market. While fully transparent PC keycaps are gaining popularity—particularly for magnetic-switch keyboards—they typically feature side-printed or laser-etched legends, leading to a decline in options for traditional top-surface, shine-through legends. The logic behind conventional top-shine-through keycaps is simple: an opaque shell contains a cutout in the shape of a character, allowing light to escape only through that specific area. While this creates a clean visual aesthetic, the lighting effect is limited and fails to align with the growing trend toward “full-body” illumination seen in transparent PC keycaps.
The “Prism” solution redefines the shape and scope of the light-transmitting area. Instead of being confined to the legends, the transparent PC component extends upward to the top edge of the keycap, forming an “L-shaped” light-transmitting structure. This means that backlighting is not only emitted through the legends but also diffused across the transparent top surface of the keycap. Furthermore, the bottom-aligned placement of the legends ensures they are perfectly positioned to catch the light from the south-facing LEDs found on many modern keyboards. The visual effect of this design is that the legends appear as silhouettes suspended within a glowing block, rather than as bright cutouts on an opaque surface. XVX describes it as follows: “The legends appear as soft silhouettes floating inside a luminous block, rather than as sharp-edged cutouts.”
II. Material Roles: ABS for Structure, PC for Light
The “Prism” keycaps utilize a dual-material (ABS+PC) double-shot injection molding process. The transparent sections are made of frosted, matte-finish PC, while the opaque portions—comprising the legends and the keycap housing—are made of ABS.
The division of labor between these materials is clear. PC offers superior light transmission and toughness; the frosted finish causes light to diffuse within the keycap, preventing the harsh “hot spots” that would occur with clear, glossy PC. ABS ensures the clarity of the legends and provides structural rigidity, while the double-shot molding process guarantees that the legends will never wear off.
There is a subtle, softened step where the two materials meet. The surface texture has been unified, resulting in a smooth, grain-free feel that is pleasant and soft to the touch. The edges on the right side of the keycaps are rounded to prevent any sharp or abrasive sensation against the user’s fingers.
It should be noted that this “full-keycap illumination” effect relies on the keyboard’s RGB backlighting. On a keyboard without backlighting—or with weak backlighting—the Prism keycaps appear more like standard, frosted, solid-colored keycaps, as the transparent sections do not emit light on their own. XVX clarifies that when the lights are off, the set presents as a clean, frosted, monochromatic keycap set; however, the design intent—achieving full-keycap light diffusion—truly requires a backlit or RGB-equipped keyboard to be fully realized.
III. Bottom-Aligned Legends and Compatibility with South-Facing LED Keyboards
The legends on the Prism keycaps are positioned at the bottom, a design tailored for the currently prevalent “south-facing” LED keyboards. In such keyboards, the LEDs are located beneath the switches (closer to the user); by placing the legends at the bottom, the translucent areas are positioned directly over the LEDs, ensuring the shortest possible light path and maximum efficiency. On keyboards with north-facing LEDs, the legends on the “Prism” keycaps are positioned further away from the light source, which reduces their brightness; however, the transparent top section can still capture some scattered light from above. A review by “in-Peripherals” (in外设) notes that these keycaps perform best on keyboards with both top and bottom transparent sections (or dual-LED configurations), suggesting a degree of flexibility regarding LED placement—though south-facing or dual-LED setups remain the ideal choice.
IV. Configuration and Specifications
The Prism keycaps feature an OEM profile and are available in three colors: white, pink, and black. The base kit consists of 97 keys, covering common layouts such as 60%, 61, 63, 64, 68, 75, and 87-key configurations. Some retail channels also include a 29-key PC (polycarbonate) add-on set with printed legends, allowing for a “two-tone” or mixed-style aesthetic.
The stem uses the standard MX-style cross-mount, ensuring compatibility with both genuine MX switches and MX-style clones—including both mechanical and magnetic switches. This provides a practical compatibility guarantee for users of modern magnetic-switch keyboards.
V. Limitations and Use Cases
The design philosophy behind the Prism keycaps involves clear trade-offs.
Their primary strength lies in the “volume” of their lighting effect. While traditional shine-through keycaps make only the legends themselves glow, the Prism keycaps make the entire keycap illuminate, with the legends appearing as the brightest areas. For users who want to cultivate an RGB-rich desktop atmosphere while still requiring clear, legible top-printed legends, this combination is relatively rare among existing shine-through keycap sets.
The drawback is that the lighting effect is entirely dependent on the keyboard’s backlight. If the RGB brightness is insufficient, or if the user prefers to keep the backlighting turned off, the transparent PC sections will not display any special effects—the keycaps will simply look like a set of frosted, opaque caps. Their design value is only fully realized in low-light environments with the backlighting enabled.
Because the legends are positioned toward the bottom of the keycaps, their brightness will be reduced when used on keyboards with north-facing LEDs. If your keyboard has north-facing LEDs, you should expect the legends to be less bright than they would be on a keyboard with south-facing LEDs.
