Problems solved by technology

[0003] Specific examples of damage to keyboards include: (i) the key print is often partially or completely erased after a very short period of time (e.g., only a few weeks); (ii) dust or other foreign material (e.g., food particles, soot, liquids, etc.) get between the keys in the keyboard, often causing malfunctions; and (iii) after a short time (e.g., only a few weeks), the key switches are destroyed

Embodiment Construction

[0028] The invention provides a peripheral device for a computer system. More particularly, the present invention provides a keyboard with ultra-durable keys.

[0029] One aspect of the invention relates to maintaining the printing on the keys of a keyboard without wearing it off. The inscription on the key contains characters, symbols and text providing information about the function the key performs when pressed by the user. In one embodiment, this is achieved by not having the user's fingers directly touch the printing on a conventional keyboard, but having a protective covering between the printing and the portion of the key that is contacted by the user's finger. The protective covering may be transparent or translucent so that the user can see the printing on the keys through the protective covering. According to one embodiment, the inscription is back-illuminated such that characters in the inscription may be visible in low light environments.

Abstract

The application case refers to a keyboard with back-lighted ultra-durable keys. A key for a keyboard includes a keycap having a top surface configured to be contacted for pressing the key down, and having a bottom. The keycap is substantially transparent. An intermediate layer is coupled to the bottom of the keycap. The intermediate layer is translucent and includes a top and a bottom. The top of the intermediate layer faces the bottom of the keycap. A character layer is positioned between the bottom of the keycap and the top of the intermediate layer. A resilient member is coupled to the bottom of the intermediate layer. The resilient member is translucent and is configured to direct light through the intermediate layer, through the character layer, and out from the keycap. The character layer is configured to be lighted for viewing through the keycap.

Description

technical field [0001] The present invention relates to peripheral devices for computer systems. More particularly, the present invention relates to a keyboard with back-illuminated ultra-durable keys. Background technique [0002] Computer use is ubiquitous and becoming more common throughout the world. Numerous computers are used in multi-user environments, such as Internet cafes, schools, colleges, etc., along with their accompanying peripheral devices. Especially in a multi-user environment where the computer and accompanying peripherals are used by users who do not own them, the use of peripherals such as keyboards and mice can be quite frequent and harsh on the devices. Consequently, peripheral devices and in particular input devices such as keyboards are subject to significant wear and tear. Wear is exacerbated by certain "heavy" users, such as gamers who can damage peripherals such as keyboards very quickly. [0003] Specific examples of damage to keyboards inclu...
