Liquid Crystal Display (LCD) TVs have become an integral part of our daily lives, providing us with endless entertainment options and a window to the world.

- LCD Panel: This is the layer that contains the liquid crystals that block or allow light to pass through to create images.
- Polarizing Filters: These filters are used to polarize the light and create the images on the screen.
- Color Filters: These filters are used to create the colors on the screen.
Types of LCD TV Screen Damage
LCD TV screens can suffer from various types of damage, including:
- Cracks: Cracks can occur due to physical impact or stress on the screen.
- Shattered Glass: The glass layer on the screen can shatter due to physical impact or stress.
