AMOLED or IPS LCD Display: Understanding the Differences
When purchasing a new smartphone, tablet, or television, one of the key specifications you’ll encounter is the type of display used in the device. Two of the most common types are IPS LCD and AMOLED. While both are highly popular, they have distinct differences that can impact your viewing experience. Understanding these differences is crucial for choosing the right display, whether for work, entertainment, or everyday use. As a part of our blogging category named as Web Tech, we dive deeper into the technology behind both AMOLED or IPS LCD display, covering key factors such as brightness, colour accuracy, power efficiency, and more.
1. Technology
IPS LCD (In-Plane Switching Liquid Crystal Display):
IPS LCD technology has been around for many years and is well-established in the display market. It operates by using a backlight, typically LED, which illuminates the liquid crystals in the display. The liquid crystals are arranged in such a way that they twist and align horizontally when electricity is applied, allowing light to pass through and create images on the screen. Because of the backlight, IPS LCD displays tend to have consistent brightness and color reproduction across the entire screen, regardless of the environment. This makes them reliable for professional uses where color accuracy is essential.
AMOLED (Active Matrix Organic Light Emitting Diode):
In contrast, AMOLED displays rely on organic compounds that emit light when an electric current passes through them. This allows each pixel in an AMOLED display to emit its own light independently. Therefore, AMOLED displays do not require a backlight, resulting in higher energy efficiency and thinner panels. The independent lighting of each pixel also allows for deeper contrast ratios, making AMOLED displays particularly effective for showing content with high dynamic ranges (HDR).
2. Colour Accuracy and Saturation
IPS LCD:
IPS LCDs are known for their natural and accurate colour reproduction, which makes them a top choice for professionals such as graphic designers, video editors, and photographers. Since the display is backlit, it produces consistent and realistic colours. While the colours on an IPS LCD may seem less vibrant than those on an AMOLED display, this accuracy makes them more suitable for tasks requiring precise color matching. For instance, a designer working on a project where color fidelity is critical would benefit from using an IPS LCD screen.
AMOLED:
AMOLED displays are typically characterized by highly saturated colors, which many consumers find appealing for entertainment purposes. The vibrant and punchy colors make images and videos pop, providing an immersive experience. However, the higher saturation can sometimes distort color accuracy, making AMOLED displays less ideal for tasks that require true-to-life color reproduction. Advances in AMOLED technology, such as Samsung’s Super AMOLED, have improved color accuracy over the years, narrowing the gap between AMOLED and IPS LCD displays for professional use.
3. Brightness
IPS LCD:
One of the main advantages of IPS LCD displays is their brightness. Thanks to the backlighting, they can achieve higher brightness levels than AMOLED displays, making them easier to view in bright or outdoor environments. This makes IPS LCD displays a strong choice for people who frequently use their devices in direct sunlight. The even distribution of brightness across the screen ensures that no area is too dark or too bright, which enhances visibility in various lighting conditions.
AMOLED:
While AMOLED displays are improving in terms of brightness, they traditionally lag behind IPS LCD in this area, especially in outdoor settings. The individual lighting of pixels can sometimes struggle in extremely bright environments. However, modern AMOLED displays have made significant strides in improving sunlight visibility by incorporating technologies like adaptive brightness, which dynamically adjusts the screen’s brightness based on the surrounding lighting. AMOLED’s brightness is also complemented by its exceptional contrast levels in low-light settings, making it ideal for indoor use or in darker environments.
4. Contrast and Black Levels
IPS LCD:
IPS LCD displays, due to their backlighting, have some limitations when it comes to displaying true blacks. Even when showing dark scenes, the backlight bleeds through the liquid crystals, making blacks appear slightly grayish rather than deep black. This limits the contrast ratio of IPS LCD displays, though it is usually sufficient for most use cases. Still, those who prioritize a cinematic experience with deep blacks and high contrast might find IPS LCD displays somewhat lacking in this regard.
AMOLED:
The ability of each pixel in an AMOLED display to emit its own light—and turn off completely—gives it a significant edge in producing true blacks. When a pixel is turned off, it emits no light, resulting in perfect black levels. This capability leads to an “infinite” contrast ratio, which makes AMOLED displays particularly attractive for watching movies, playing video games, or viewing HDR content. Deep blacks and vibrant colors combine to create a more immersive viewing experience, making AMOLED a favorite among enthusiasts who want rich visuals.
5. Power Efficiency
IPS LCD:
IPS LCD displays, due to their reliance on a constant backlight, tend to consume more power than AMOLED displays. This can especially affect battery life in devices such as smartphones, where the display is one of the most power-hungry components. The power consumption is typically higher when the screen brightness is set at maximum, or when the display is showing mostly white or bright images, as the backlight needs to stay on at all times.
AMOLED:
AMOLED displays are known for their power efficiency, particularly when displaying darker images or themes. Because black pixels are turned off completely, AMOLED displays consume significantly less energy when showing dark or black content. This is why many smartphone manufacturers offer “dark mode” as an option, which not only reduces eye strain in low-light conditions but also extends battery life on devices with AMOLED screens. However, displaying bright content for long periods can still draw more power, though not as much as an IPS LCD display.
6. Durability and Lifespan
IPS LCD:
IPS LCD displays are generally more durable over time compared to AMOLED. The backlight used in IPS LCDs does not degrade as quickly as the organic materials in AMOLED displays. As a result, the risk of color degradation and pixel deterioration is lower in IPS LCDs. These displays also maintain their color accuracy over long periods, making them a dependable choice for long-term use.
AMOLED:
One downside of AMOLED technology is the potential for burn-in, a phenomenon where static images left on the screen for extended periods can leave a permanent mark. However, newer AMOLED technologies have significantly reduced the risk of burn-in by implementing features like pixel shifting and automatic brightness adjustments. Despite these improvements, burn-in can still be a concern for users who frequently display static elements on their screen, such as navigation bars or widgets. Additionally, AMOLED displays may degrade faster over time, leading to color shifts or reduced brightness.
7. Cost
IPS LCD:
The long-standing history of IPS LCD technology has made it more cost-effective to produce. Devices featuring IPS LCD displays are generally more affordable, which is why they are commonly found in budget and mid-range devices. The lower production cost doesn’t necessarily imply lower quality, as IPS LCD displays still provide excellent performance for everyday use.
AMOLED:
On the other hand, AMOLED displays tend to be more expensive to manufacture due to their advanced technology. This cost is reflected in the price of devices that use AMOLED screens, often found in flagship smartphones and premium gadgets. However, for many users, the superior visual quality, thinner design, and energy efficiency of AMOLED displays justify the higher cost.
Conclusion:
Both IPS LCD and AMOLED displays have their strengths and weaknesses, catering to different user preferences and use cases. IPS LCD is ideal for those who prioritize color accuracy, brightness, and durability, making it a reliable choice for professional tasks. AMOLED, with its deep blacks, vibrant colors, and energy efficiency, is perfect for users seeking a more immersive viewing experience, especially for entertainment purposes. By understanding the differences between the two technologies, you can make an informed decision that best suits your needs, whether it’s for watching movies, working on creative projects, or simply enjoying everyday tasks.
