Which of the following is the MOST likely light source for a laptop screen? (Select TWO).

CCFL (Cold Cathode Fluorescent Lamp) has been a long-standing backlight technology in laptop LCD screens, using a fluorescent tube behind the panel to provide illumination.

CRT (Cathode Ray Tube) is a bulky vacuum-tube display technology used in older desktop monitors and televisions, not in laptop screens.

Plasma display technology uses ionized gas cells to emit light and is found in large flat-panel televisions, not laptop displays.

Matrix is not a light-source technology; it refers to the arrangement of pixels in an LCD panel and does not describe how light is generated.

LED (Light Emitting Diode) backlighting has become the dominant modern laptop display technology because it is thinner, more energy-efficient, and produces no mercury waste compared to CCFL.
