Light emitting keyboard and light guide plate module thereof

Abstract

The invention provides a light emitting keyboard and a light guide plate module thereof. The light emitting keyboard comprises a light emitting element, a thin film circuit board, a plurality of press keys and the light guide plate module, wherein the press keys correspond to a plurality of thin film switches on the thin film circuit board and are communicated with the thin film switches, the light emitting element is used for providing light rays for the light emitting keyboard, the light guide plate module comprises a first reflective layer, a second reflective layer and a light guide layer, the light guide layer is positioned between the first reflective layer and the second reflective layer, and is provided with a plurality of light emitting areas and a gap area, the light emitting areas correspond to the press keys, the gap area is positioned outside the light emitting area, each light emitting area is provided with light guide points, and the gap area is provided with a light diffusion structure.

Description

Technical field [0001] The invention relates to a keyboard, in particular to a keyboard with a light-emitting function and a light guide plate module thereof. Background technique [0002] In recent years, due to the rapid development of the information industry, many users may use portable information devices, such as notebook computers, mobile phones, or personal digital assistants, in different environments. In a low-light environment, the user may not be able to see the numbers and words marked on the keyboard keys, which may cause difficulty in operation. In severe cases, the user may even have visual impairment due to reluctance to recognize the key markings. Therefore, the introduction of the luminous keyboard 1 can improve the inconvenience of users in using the keyboard in places with insufficient light. What's more, with different light emitting configurations, the information device using the light emitting keyboard 1 can look more beautiful, thereby increasing its sa...

Problems solved by technology

[0007] However, the disadvantage of the existing luminous keyboard is that, due to the light incident on the light guide plate 12, the incident angle of part of the light beam L12 is too small, that is, the traveling direction of the light beam L12 is too flat, so the light beam L12 is not easy to hit the light guide point 121. , the light beam L12 cannot be derived from the light guide plate 12 to be used by multiple keys 15, resulting in poor light use efficiency; therefore, the existing luminous keyboard still has room for improvement
