Backlight is widely used in many human-machine interface applications for electronic equipment. Different from conventional backlight solution, up-to-date backlight keypad uses side-firing LEDs with LGF (light guide film) technology to illuminate the buttons or the areas that needed to be uniformly illuminated.

Backlight technology greatly enhances the customer's user experience without any doubt. Initially, its purpose is helping the users see the texts on the interface more clearly in the dark environment. But now, improving the interface's aesthetic and fashion sense is becoming a more and more important purpose of backlight design. That is why backlight has been increasingly being applied to electronic products in the recent decade.

The size and distribution of light guide dots have a significant impact on the backlighting performance. Poorly designed light guide dots can lead to substantial loss of LED light, resulting in an unsatisfactory visual effect across the backlit area. Elecflex engineers employ a unique light guide dot design to minimize the loss of light, which enables illumination of the largest possible area using the fewest side-emitting LEDs, achieving high brightness and excellent uniformity

Notably, leveraging our advanced light guide design capabilities, we can replicate the functionality of a seven-segment digital display. This innovative approach allows customers to eliminate traditional seven-segment displays, significantly reducing costs and greatly minimizing the overall size of the product. A 7-segment display integrates into a 1mm thick stylish keypad. That's amazing.
