AMOLED and POLED technologies are distinct display technologies developed by Samsung and LG in South Korea, both falling under the OLED technology category. So, how can we distinguish between AMOLED and POLED displays and the technologies they produce? Let’s explore this through this article!
What is AMOLED?
AMOLED is a product developed by Samsung Electronics through a unique process that combines an active matrix with organic light-emitting diodes. It achieves independent control and superior display effects via the TFT (thin-film transistor) and storage capacitor within each pixel, enhancing our usage and viewing experience.
What is POLED?
POLED represents LG’s most innovative OLED technology. It replaces the traditional glass substrate with a plastic substrate offering superior thinness and flexibility. This enables the creation and mass production of creative displays featuring curved or foldable properties, making them highly portable.
How do AMOLED and POLED displays differ in performance and functionality?
Having explored the core concepts of AMOLED and POLED technologies, we will now delve into the specific differences between displays manufactured using these two approaches!
Nit Brightness
AMOLED displays primarily utilize low-frequency PWM dimming technology to adjust nit brightness. This technique rapidly switches LED light sources to control overall screen brightness output, delivering high-luminance visuals that ensure screen content remains visible across varying ambient light conditions.
It’s important to note that when AMOLED displays operate at low frequencies, the human eye can perceive noticeable flickering. This can cause adverse effects such as visual fatigue and dryness.
Compared to AMOLED displays with a single organic light-emitting layer, POLED displays are primarily constructed using a dual-layer organic light-emitting structure (dual-layer Tandem OLED technology), enabling superior brightness performance.
The light-emitting diodes within POLED displays employ an RB-GB (Red-Blue-Green-Blue) Pentile arrangement. This effectively reduces blue light wavelengths, alleviating visual fatigue and delivering a more comfortable viewing experience.
Contrast and Color Rendition
AMOLED and POLED displays exhibit virtually identical contrast and color performance. Both utilize self-emissive OLED components to achieve perfect blacks and whites, dividing the spectrum into equally sized zones for balanced transitions and rich color detail, delivering an immersive viewing experience.
Impact Resistance
POLED displays primarily utilize plastic substrates, offering strong impact resistance and flexibility. Even if accidentally dropped, they maintain a stable image display.
AMOLED displays primarily use glass substrates, which are hard, brittle, and prone to shattering. To enhance protection, manufacturers incorporate flexible spacers or other protective components to prevent screen damage from accidental drops.
Power Consumption
To compare the power consumption of AMOLED and POLED displays, we ordered both types online. Using precision power supplies and professional equipment like System Trace, we recorded and analyzed the energy consumed by each display when presenting identical scenes: full white, full black, and the same static image.
The energy fluctuation charts from the professional equipment clearly show that each energy fluctuation point on the AMOLED display is slightly lower than that of the POLED display. This indicates that AMOLED displays consume less energy than POLED displays, making them more energy-efficient. Long-term use can help significantly reduce electricity costs.
Applications
AMOLED technology delivers low power consumption and high contrast, making it ideal for displays in tablets, premium televisions, smartwatches, and similar devices. POLED technology enables slight curvature and high brightness, making it suitable for automotive displays, curved smartphones, foldable phones, and similar applications.
For larger screens with superior image quality, LED displays are the preferred choice!
AMOLED and POLED technologies are primarily suited for smaller projects. For larger displays with superior image quality, LED displays manufactured using LED technology should be prioritized!
LED displays feature a modular design, utilizing LED modules and LED cabinets of varying sizes to achieve custom dimensions tailored to specific project requirements. Furthermore, LED displays are crafted with premium circuit designs and renowned brand components, boasting a lifespan of 100,000 hours for reliable, round-the-clock service!
In terms of display performance, LED screens significantly outperform AMOLED and POLED displays in contrast, brightness, and other parameters. Their high-brightness capability, in particular, enables them to withstand direct sunlight—a feature unmatched by other display technologies.
Frequently Asked Questions
Do AMOLED and POLED displays develop green lines?
Yes. After prolonged use, the internal flexible printed circuits (FPC) in AMOLED and POLED displays may degrade or fracture due to factors like repeated bending and pressure, leading to green line artifacts on the screen.
Do POLED displays have a longer lifespan than AMOLED displays?
Yes, POLED displays are more durable than AMOLED displays, boasting a lifespan of 50,000 hours compared to AMOLED’s 40,000 hours.
Can POLED and AMOLED displays suffer from burn-in?
Yes. When POLED and AMOLED displays show the same image for extended periods, the brightness of their self-emitting pixels gradually diminishes over time, leaving permanent phosphor imprints on the screen. If burn-in causes black spots, refer to this guide for a simple repair.
