After breaking down the display unit of XEL-1, Sony Corp's OLED TV, the Nikkei Electronics Breakdown Team started to disassemble the TV mount.
Part of the mainboard appeared when we removed the arm connected with the cover on the back side of the TV mount and display unit. Then we found a peculiar metal part on the mainboard.
"What is this?" we thought as we removed the front face of the mount chassis. There was a block of Cu covering the entire mainboard. The Cu block was a heat dissipation unit that included a radiation fan and heat pipes.
We took out the dissipation unit and found that a number of heat radiation sheets were attached on the back side of the mainboard and the unit. For a TV, these were unusually strong measures being taken against heat. The heat density is thought to be higher because the mainboard is smaller than that used in the existing LCD or PDP TV. This must be why Sony took the measures that are rarely seen in the standard TVs.
