Hmm, I've now noticed N-Card have problems with Chocobo Tales.
One-Third though game, it would crash after playing a minigame. I've restarted the games and still no luck. Other minigames are no problems. Just that one in the game where it causes the game to crash.
Backlight can be one giant light panel with a diffusor, but recently there's mini/micro LED backlighting, where you can control the light level for smaller areas of the screen, to get better contrast and color range.
