| [title] Internal Boards 4 | |
| [* black] This is the LED backlight's controller. The backlight seems to run on a fairly high voltage and the backlight cable is thus quite thin (right angle cable in the first image.) It is covered by plastic cover. | |
| [* black] The controller appears to be built using a bunch of MOSFETs and inductors as a boost/buck/current limiting DC-DC converter. The board is well-cooled with a lot of heavy copper fill areas, in my experience it does not need extra cooling to be okay | |
| + | [* black] Straight ribbon cable goes to TCON to allow backlight contrast dynamic dimming and control on/off/brightness. |
