  • 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
