The keypad assembly (100) utilizes side-firing LEDs (130) mounted to a keypad flex (112) which protrude through subsequent thin layers of substrates. A light-guide film (104) disposed over the layers includes corresponding cut-outs through which the side-firing LEDS partially protrude. The light-guide film includes light dispersion areas (114) formed thereon. A cover (102) seals the side-firing LEDs (130) protruding through the light-guide film (104). An interconnect flex (132) couples to the keypad flex (112) to provide flexible coupling of the keypad assembly to an electronic device. The light-guide film (104) provides both light dispersion and sealing to the keypad assembly (100)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Keypad assembly for a communication device","description":"A keypad assembly (100) provides improved backlighting in a slim-line from factor with a minimal number of LEDs (130).
