Custom-Shaped Backlight Units (EL, CCFL & LED Edge-Lit)
(Irregular-Form Lighting Solutions for Innovative Designs)
We specialize in custom-shaped backlight units that break free from traditional rectangular constraints, enabling innovative product designs across industries. Utilizing EL (Electroluminescent), CCFL (Cold Cathode Fluorescent Lamp), and LED edge-lit technologies, our free-form backlights deliver uniform illumination for curves, circles, cutouts, and complex geometries. Ideal for devices requiring unique aesthetics or space-optimized lighting, these solutions combine precision engineering with optical excellence.
