When to Choose Electroluminescent (EL) Backlighting

When to Choose EL Backlighting

You should typically choose EL backlighting for applications in which the device doesn't require constant illumination. Some devices will produce illumination all the time. When you turn on one of these devices, they'll begin to generate light - and they won't stop until you turn off the device. EL backlighting isn't a good choice for devices such as this. Rather, you should choose EL backlighting for devices that only require temporary or intermittient lighting.

EL backlighting contains phosphor compounds. Phosphor is an electroluminescent material, meaning it releases photons when exposed to an electricalcurrent. Phosphor compounds, however, are susceptible to decay. Over time, phosphor compounds may lose their ability to generate light. This is especially true in backlighting applications where the phosphor compounds are exposed to high voltages.

You can still choose EL backlighting for devices. EL backlighting, in fact, is a popular all-around choice because of its bright light and energy-efficient properties. You can rest assured knowing that it will produce bright light while consuming a minimal amount of energy.

But for applications that require constant lighting, you may want to choose an alternative backlighting technology. EL backlighting is susceptible to decay. As its phosphor compounds begin to decay, EL backlighting may fail to generate a sufficient amount of light.
