Backlighting Membrane Switch means that the keypad can have light through it. The Logo, button rings, symbols etc. can be backlighted. There will be a light source from the backside of the keypad to light the graphic overlay and provide the signal information to users or when the product used in the night or dark environment it can light the graphic and make the users or workers make buttons press operation correctly and avoid any wrong operations.

The LGF backlighting solution is the current most popular backlighting technology. LGF is a light guide film. LGF itself is not a light source. It couldn't produce the light. It still needs the LEDs assembled on the circuit layer to produce the light source. But LGF can guide the light from the LEDs to the top overlay evenly. For this backlighting keypad, it can save the LEDs quantity and it also can get an even backlighting effect with fewer LEDs. But in this way, the difficulty is adjusting the refraction dots on the LGF layer. Adjust the direction of dots, density, position, etc. And its tool fees is also not cheap.
