On June 17, 2008, JVC announced the world’s thinnest LCD TVs with built-in tuners: its 42″ LT-421L89 and its 46″ LT-46SL89. Both weigh less and consume less power compared to other average LCD TVs. The bezel lost some thickness too. How did JVC do it?
They slimmed down the backlight unit (BLU) and the power supply substrate. The BLU is 40% smaller in depth measuring just 20mm (0.79″) deep and 13mm (0.51″) wide. The light-diffusing plates and light-reflection sheets were optimized leading to a new and slim BLU that has light uniformity at all four corners. This was done without adding additional CCFL tubes.
The power-supply substrate is in a direct-mount configuration and uses a fan-less heat dissipation system to reduce not only power consumption but noise as well. The LT-421L89 sips power: 145W, which is about half of typical LCD TVs this size. Weight has been reduced to just 12kg (26.4lbs).
