TT Electronics’ patented thin film backlighting technology uses specialised printing processes to accomplish light extraction from the light guide surface using side-emitting LEDs embedded within the light guide structure.
Transparent materials guide light through Fresnel’s Law of Refraction, particularly the phenomenon of Total Internal Reflection, as illustrated in Figure 1. In addition to fibre optic communications, this physical phenomenon is the basis for backlighting for LCD screens in mobile phones and laptops. These applications require a thin light source directly behind the liquid crystal panel to illuminate the screen.
