AI Technical Summary
The printing inks used in existing keycaps have pollution problems, and high-grade inks are expensive while low-grade inks have poor adhesion, affecting processing efficiency and user experience.
Using two-color injection molding technology, the inner shell and outer shell are molded as one piece. The texture lines on the surface of the inner shell are exposed on the surface of the outer shell through texture grooves, forming a contour pattern, which avoids the use of ink and improves production efficiency and adhesion.
This technology enables inkless keycap printing, improving the keyboard's aesthetics and user experience, reducing production costs, and maintaining long-term stability and consistent tactile feedback.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of keyboards, and more particularly to a full-page contour keycap and keyboard. Background Technology
[0002] Keyboards are crucial input devices for electronic systems. Keycaps are small, cap-shaped plastic components. Users' attention has gradually shifted from practicality to aesthetics and design. A well-designed keycap not only enhances the keyboard's appearance but also significantly improves typing efficiency, comfort, and user satisfaction. Currently, the market offers "popular contour-lined keycaps," but these are achieved through printing technology where ink adheres to the keycap for subsequent processing, resulting in secondary processing and impacting efficiency. Furthermore, the inks used in printing are often polluting and harmful to human health and the environment. Additionally, low-grade printing techniques result in weak ink adhesion, leading to degradation over time. High-grade techniques, on the other hand, offer strong ink adhesion but involve more complex printing processes and higher costs. Utility Model Content
