Samsung has pulled off another world’s first by developing the slimmest LED LCD TV panel. The 40-inch Needle Slim LED TV panel is just 3.9mm thick, which is about 7mm slimmer than Samsung’s full production LED TV panel or 46mm thinner than conventional LCD panels.

Samsung’s ultra slim panel uses new optical film manufacturing tech that allows the panel to have Edge-lit LED backlighting and sport features like full HD resolution support, 5000:1 contrast ratio and 120Hz refresh rate.
