 At IFA2008 we have demonstrated the thinnest 32’’ liquid crystal display (LCD) prototype on show. With a 1mm light guide, we have created a display prototype of only 8mm. When incorporated into a TV set, we expect that this ultra-thin LCD will make it more attractive to hang your flat-screen TV on the wall – just as you would do with a painting.
Your TV as a piece of art “At just 8mm thick, our ultra-thin display concept will enable the thinnest 32” LCD-TV,” says Fred Boekhorst, Senior Vice-President Philips Research and Program Manager Lifestyle. “Our concept is also very light – around 5 kg – enabling a 32” LCD-TV that is around 10 kg lighter than existing comparable TV sets. As a result, hanging such an LCD-TV becomes simple and easy.”
The world’s thinnest backlighting technology The novel technology involves a very thin light guide plate illuminated from the top and bottom by high-power, energy-efficient LEDs. Using Philips’ patented light in-coupling structure and a fine-tuned out-coupling pattern, light can be distributed over the whole display area in a uniform fashion.
“We’ve managed to cut the size of the light guide – which is the thickest part of an LCD – from around 25mm to just 1mm,” says Boekhorst. “The thickest part of the display has now become one of the thinnest parts, even thinner than the LCD panel. This has been key in achieving the sleek ultra-thin design.
