This is a stark contrast to AMOLED, which sometimes struggles with outdoor visibility. Moreover, LCD panels are generally more affordable to produce, which is why they’re often found in devices that prioritize cost-efficiency.
However, LCD has its limitations. The reliance on backlighting means that blacks aren’t truly black but rather a dark gray. This also results in lower contrast ratios and less vibrant colors when compared to AMOLED. Additionally, LCD screens tend to consume more power as the backlight remains on regardless of the content being displayed.
OLED Displays: The Middle Ground
OLED (Organic Light-Emitting Diodes) is the foundation upon which AMOLED technology is built, but it also stands strong on its own. Unlike LCD, OLED doesn’t require a backlight. Instead, it uses organic materials to produce light, offering better color accuracy and deeper blacks.
What sets OLED apart from AMOLED is its simpler structure, which often translates to lower manufacturing costs. While it may not offer the same level of pixel-by-pixel control as AMOLED, OLED displays still provide a fantastic visual experience with excellent energy efficiency.
