Some TV’s are OLED (Organic Light Emitting Diode). These tend to be more expensive, as manufacturers argue the technology has better black levels and contrast ratios (the range of brightness between the blackest black and whitest white the TV can produce). Personally, I don’t see that big of a difference between OLED and non-OLED. At least, not enough to justify spending $2000 on a TV. Hope this helps.
They are most likely seeds. Whatever you do, DON’T plant them. If you’re in the USA, contact someone from your state’s Agricultural Department.
