Difference Between AMOLED and LCD Display Technologies
Introduction:
AMOLED (Active Matrix Organic Light Emitting Diode) and LCD (Liquid Crystal Display) are the two most commonly used display technologies in modern smart devices. Both of these technologies have their own set of advantages and disadvantages. The choice between AMOLED and LCD technology ultimately depends on personal preference and the intended use of the device. In this article, we’ll take a closer look at the differences between AMOLED and LCD display technologies.
What is AMOLED?
AMOLED stands for Active Matrix Organic Light Emitting Diode. It’s a type of display technology that uses organic compounds that emit light when an electric current is applied to them. AMOLED displays have a high contrast ratio, deep blacks, and vivid colors. Since each pixel is self-emitting, there’s no need for a backlight. This allows AMOLED displays to consume less power compared to LCD displays. AMOLED displays also have the ability to show true blacks because individual pixels can be turned off completely.
What is LCD?
LCD stands for Liquid Crystal Display. It’s a type of display technology that uses liquid crystals to control the amount of light that passes through them. LCD displays require a backlight to provide illumination. This makes them less power-efficient compared to AMOLED displays. LCD displays also have a lower contrast ratio compared to AMOLED displays.
Differences Between AMOLED and LCD:
1. Power Consumption: AMOLED displays consume less power compared to LCD displays. This is because AMOLED displays do not require a backlight to provide illumination.
2. Contrast Ratio: AMOLED displays have a higher contrast ratio compared to LCD displays. This is because each pixel on an AMOLED display is self-emitting.
3. Blacks: Since each pixel on an AMOLED display is self-emitting, AMOLED displays have the ability to show true blacks. LCD displays, on the other hand, cannot show true blacks because they require a backlight to provide illumination.
4. Viewing Angles: AMOLED displays have wider viewing angles compared to LCD displays. This is because AMOLED displays do not require a backlight to provide illumination.
5. Color Reproduction: AMOLED displays have more vivid colors compared to LCD displays. This is because each pixel on an AMOLED display emits its own light.
Conclusion:
The choice between AMOLED and LCD technology ultimately depends on personal preference and the intended use of the device. AMOLED displays have a higher contrast ratio, deeper blacks, and more vivid colors. They also consume less power compared to LCD displays. LCD displays have a lower contrast ratio and require a backlight to provide illumination. They’re also more affordable compared to AMOLED displays.
