Technologies that realize the super-slim form

Intelligent Engineering through Original Developments

The super-slim design was made possible through the use of a new JVC-developed slim panel backlight unit and power supply substrate, or chassis. The new slim LCD panel backlight unit is 40 percent smaller (with a mere 20mm depth and 13mm width) in depth and bezel width compared to a conventional LCD backlight. What’s more, the unit weighs only 12kg and consumes just 145W (see diagram 1) of power.

Original Backlight Unit

JVC’s display engineering team succeeded in developing a new, slimmer backlight unit by optimizing the light-diffusing plates and light-reflection sheets, as well as improving their overall composition. This provided uniform light-diffusion at all the corners and edges without the addition of more CCFL tubes, while maintaining adequate luminance to ensure that the screen always remains bright (see diagrams 2 and 3).

Efficient Power-supply Substrate

To further reduce power consumption, JVC also developed a slimmer yet efficient power-supply substrate and employed a direct-mount configuration for it on the LCD panel backlight unit with a fan-less heat dissipation system.
