Electroluminescent Lighting (EL)
EL lighting can be incorporated into membrane keypads, and is achieved through a printing process, thus giving great flexibility in customizing the design to your specific application.
A layer of phosphorescent material is printed between two conductive electrodes. When an AC current is applied to the electrodes the phosphor emits light.
This technology has a definite life cycle – in a typical application, this would be a half life of about 3000 hours. EL panels are driven by an AC source, commonly 120AV at 400Hz. An inverter derives this from DC supply of 5-24VDC. The higher the frequency, the higher the light output. The lifetime is also inversely correlated to the frequency – increased light intensity reduces lifetime. Often the Integration of a light sensor or timer within the circuit to switch the panel on and off extends the effective life of the EL panel.
Electroluminescent Lighting Panels are sensitive to humidity, moisture, and UV light, all of which are taken into account at the design stage.

Advantages of Light Emitting Diodes:
- Long life (more than 100,000 hours), making it a reliable light source
- Cost-effective
- Efficient low voltage power consumption
- Available in a wide variety of colors and intensities
Light Guide Film (LGF) is a thin film backlighting technology that will direct light produced by side-firing or right-angle LEDs across the area that needs to be backlit. The advantage of LGF is that the film can be fabricated into almost any shape, providing consistent backlighting across one or more areas within the switch.Multiple LGF films can be used within one application to provide discrete backlighting to different graphic features. Different colored LEDs can be used to achieve unique lighting effects or white LEDs can be used to light different printed graphics on the overlay.
Advantages of Light Guide Film:
- Manufactured in almost any shape
- Very thin for smaller, lighter devices
- Minimal impact on the tactility of the membrane switch buttons
- Uniform backlighting across all areas

How to use Backlight Membrane Switch?
The Backlight Membrane Switch is generally used in a low-light environment. This is because the absence of an external light source can cause problems with operating the Membrane Switch. Industrial equipment that needs to be used for a long time in the dark or in a low-light environment. In a medical environment, if the elderly need to make an emergency call in the dark, the Backlight Membrane Switch can be used. This is because the Backlight Membrane Switch can give people a striking reminder in the dark. If it is a hunting machine in a hunting environment, then hunter players usually need to hunt in a dark environment, and the Backlight Membrane Switch helps users and players to see the switch clearly, so as to use the hunter to capture.
