Which of the following is an advantage that OLED displays have over LCD displays?
The correct answer is B. The power consumption is lower.. OLED (Organic Light-Emitting Diode) displays consume less power than LCDs, particularly when displaying dark content, because each OLED pixel generates its own light and pixels displaying black simply turn off completely, drawing no power. LCD panels require a constant backlight

Explanation
OLED (Organic Light-Emitting Diode) displays consume less power than LCDs, particularly when displaying dark content, because each OLED pixel generates its own light and pixels displaying black simply turn off completely, drawing no power. LCD panels require a constant backlight regardless of what is displayed. Option D ('A backlight is utilized') actually describes LCD technology, not OLED - this is an LCD characteristic, not an OLED advantage. Option A is incorrect because OLED displays are actually prone to color degradation and burn-in over time. Option C is misleadingly worded - while OLED's superior contrast ratio does enable better grayscale reproduction, this is not the primary or most well-known advantage tested on certification exams.
