2. Black Splotches or Ink Spots of Various Sizes
The internal glass has cracked allowing the liquid crystal to pool into areas of the screen.
Internal cracks typically occur due to excessive force on the screen. This can be the result of some object hitting the screen, a drop, or even improper handling during installation. Such effects may not appear immediately and may increase in size and visibility over time.

3. Dark or Light Spots of Various Sizes
Spots typically occur due to an external force hitting the screen or pressure from the sides (bezel edges) from handling or installation causing damage to the LCD panel’s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect. Such effects may not appear immediately and may increase in size and visibility over time.
