I am one of these guys who bought an Official Raspberry Pi Display right after it appeared on the market. The controller shipped with these early displays was version 1.0 of the board. As I would love to have the ability to adjust the backlight of the display I am desperately looking for a newer controller board (version 1.2) on which these features are enabled / possible.
Are there any plans to sell the controller board separat of the full display kit? My panel is working fine and I think it's a pity that you can't update the controller board without buying a whole new Official Raspberry Pi Display.
