LOW PROFILE KEYBOARD BACKLIGHT MODULE

摘要

A low profile keyboard backlight module includes an electrically insulative bottom membrane layer, an intermediate membrane layer including a conducting layer, an insulative layer and a light-emitting layer attached together through lamination and bonded to the top surface of the bottom membrane layer, and an electrically insulative top membrane layer bonded to a top surface of the intermediate membrane layer opposite to the bottom membrane layer and having an integrated elastic layer located at a top surface thereof to support a set of keys. Thus, the low profile keyboard backlight module provides optimal waterproof effects and is practical for use in an electronic product having light, thin, short and small characteristics.
