Description

Technical Field

[0001] The utility model relates to the technical field of luminous keyboards, in particular to a keyboard backlight module. Background Art

[0002] Keyboards are currently the most commonly used input devices, found in computers, personal digital assistants, mobile phones, and any other electronic device requiring key input. Beyond their basic function as input interfaces, keyboards also require users to accurately press keys in low-light environments to avoid input errors. This is where illuminated keyboards come in.

[0003] Existing illuminated keyboards are not only designed to adapt to low-light environments, but have also evolved into a standard for improving user experience for some users. For example, users who prefer glare effects seek an overall luminous experience for the keyboard. However, most existing keyboards use unidirectional light-emitting elements, which can only emit light from the top or bottom. If both sides of the keyboard are to be illuminated, twice as many light-emitting elements must be deployed, which not only increases costs but also affects the keyboard layout, hindering the optimization of the keyboard structure. Therefore, a keyboard backlight module is needed. Utility Model Content
