OLED offers advantages in image quality with deeper blacks, vibrant colours, and high contrast ratios. OLED displays also have better viewing angles, higher refresh rates, and are more energy-efficient. However, OLED displays are susceptible to screen burn-in and come at a higher price. LCD displays provide good colour reproduction and are commonly found in lower-priced iPhone models. The choice between OLED and LCD depends on individual preferences and budget considerations, with OLED being preferred for superior visual performance.
