A customer's cell phone screen is discolored in several areas. Which of the following components is the MOST likely cause of the issue?

A bulging battery can cause screen distortion or physical damage due to pressure, but it typically doesn't directly cause localized discoloration of the display itself.

Wired connectors connect the display to the main board; issues with these usually result in no display, flickering, or complete loss of function, not typically localized discoloration.

The Liquid Crystal Display (LCD) is the component responsible for producing the visual image on the phone screen. Discoloration, dead pixels, or uneven brightness are direct symptoms of damage or failure within the LCD panel or its backlight components.

A phone case is an external accessory and cannot cause discoloration on the screen itself.

Protective glass is the outermost layer and while it can crack, it does not cause discoloration of the underlying display image.
