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, lighter, and consumes less power than conventional LCD backlight units (see diagram 1).

Original Backlight Unit
JVC's display engineering team succeeded in developing a new, slimmer backlight unit by optimising 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. With conventional backlight units, it was difficult to achieve efficient heat dissipation due to the substantial thickness of the power-supply substrate. However, the new substrate incorporates improvements such as the use of a higher density IC and fewer, more compact parts inside which are coated with black alumite — all of which help to better dissipate heat from the substrate itself while also making the air vent thinner.
