    • Backlight-guide-board is the primary component of keyboard display, its brightness is related to the display effect of the whole keyboard.
    • LGF Module is composed by Guide-film , Diffusion film and Reflection Film .
    • The uniformity of backlight is mainly related to the dot of the LGF , which is located at the bottom of the LGF. Because of the direct LED light , the single-side backlight emitting  gradually increases from the nearby position to the opposite side, becomes larger and larger, which is conducive to the reflection of light in a large area

    KEYBOARD LGF Module Feature :

    • a) Good Luminous Effect, Uniform Brightness, High Light Intensity
    • b) Light Weight ,Thinner Thickness and Small Volume
    • c) Save LED lamps ,Save Power Consumption
    • d)Good Stability , Long life-time


    KEYBOARD LGF Module Working Principle

    • The LED lamp will turn on after switch on , the light emit to every area through the dot of LGF , Using the principle of light reflection and refraction, combined with special optical software design, to make "dot light source" enlarge "plane light source".
