PMOLED vs AMOLED displays
The current top-of-the-line display technology is OLED, which stands for organic light-emitting diode. The OLED is built from an electroluminescent layer that consists of organic compounds which emit light when an electric field is applied. Due to their light emitting characteristics, OLED-based panels do not need backlighting, what enables much thinner and larger display sizes than competing technologies.
OLED displays are quite versatile. In fact, virtually all premium devices currently on the market feature OLED displays. Below is a classification by different categories. In this article we focus on Passive-Matrix and Active-Matrix OLEDs and explain both technologies and their applications.
Main differences
The difference between AMOLED and PMOLED lies in the driving electronics, which can be either a Passive Matrix (PM) or an Active Matrix (AM). In PMOLED displays, each pixel is briefly turned on and then allowed to decay until the next refresh cycle. The higher the refresh rate, the sharper the image. In AMOLED displays, each pixel is actively controlled and remains on or off continuously, providing the highest contrast but at a higher cost, in comparison to PMOLED.
AMOLED displays
The first AMOLED displays were introduced in the early 2000s, with Samsung being the first company to commercialize them. Over the next few years, the technology began to be adopted in smartphones, tablets, smartwatches, and smartbands, as well as in laptops and TVs. Today it’s clear that AMOLED technology has become well-established in the consumer market and continues to expand into an increasing number of applications.
In the latest market forecast, OMDIA predicts OLED shipments to surpass one billion units for the first time in 2025. “In the smartphone market, Omdia says that there has been significant growth, mainly driven by Chinese OLED producers (BOE, CSoT, Visionox, Tianma and Everdisplay). In addition to the growth in smartphone displays, OLED are expanding into new applications, including AR/VR and automotive displays.”1 The other company, Research and Markets, estimates that AMOLED display market will grow at a CAGR of 15.56% to reach US$64.61 billion by 2030, from US$31.35 billion in 2025.2
This growth is driven by the increasing demand for high-resolution and brighter displays in consumer electronics.
When it comes to technicalities, an AMOLED display consists of an active matrix of OLED pixels that emit light (luminescence) when electrically activated. These pixels are deposited or integrated onto a thin-film transistor (TFT) array, which acts as a series of switches controlling the current to each individual pixel. What’s important, AMOLEDs have no limitations in terms of size or resolution.
PMOLED displays
Passive matrix OLED displays have gained significant popularity in recent years, particularly within the industrial sector, but also in wearable devices, compact gadgets, and secondary (sub) displays. Their vivid colors, contrast, high resolution, and slim form factor make them an appealing option for developers of industrial applications—especially when replacing passive LCD displays.
But the technology has a longer history. It was utilized by the earliest OLED-based products on the market, such as MP3 players, sub-displays in mobile phones, and radio interface panels in automobiles.
According to Research Nester, in 2025 PMOLED market is assessed at USD 3.42 billion. “The global market size was worth more than USD 3 billion in 2024 and is poised to witness a CAGR of over 17.5%, crossing USD 24.41 billion revenue by 2037. North America is set to earn USD 14.65 billion by 2037, driven by strong demand for energy-efficient display solutions in wearable technology, automotive dashboards, and industrial applications”3.
A PMOLED display is composed of multiple layers. The anode forms the organic layer, while the cathode is structured in rows positioned perpendicularly to the anode. Both layers are arranged in a strip-like pattern. A passive matrix display operates using a simple control scheme in which each row (anode and cathode line) is addressed sequentially. PMOLED electronics do not include storage capacitors, which means pixels are not active for the majority of the time. To achieve adequate brightness, higher voltage levels are required.
Although PMOLEDs are relatively easy to manufacture and cheap, they are less energy efficient. Additionally, the OLED materials tend to have a shorter lifespan due to the elevated voltages involved. These displays are also limited in resolution and size, as increasing the number of lines necessitates higher voltage.
Summary of key differences between AMOLED and PMOLED
Driving technology:
- AMOLED: Uses an Active Matrix, where each pixel is individually controlled by thin-film transistors (TFTs).
- PMOLED: Operates on a Passive Matrix system, where rows are activated sequentially, without individual pixel control through transistors.
Image quality:
- AMOLED: Delivers higher resolution, brighter output, and superior contrast, as each pixel emits its own light and stays continuously active.
- PMOLED: Offers lower resolution and brightness, as pixels are only active briefly and require higher voltage to achieve sufficient luminance.
Applications:
- AMOLED: Commonly used in smartphones, tablets, TVs, smartwatches, and increasingly in AR/VR devices and automotive displays.
- PMOLED: Ideal for small screens in wearables, industrial equipment, sub-displays, and as replacements for passive LCDs.
Manufacturing & cost:
- AMOLED: More expensive and complex to manufacture but allows unlimited size and resolution.
- PMOLED: Cheaper and easier to produce but limited in size and efficiency. Shorter lifespan due to high voltage requirements.
Market outlook:
- AMOLED: The global AMOLED display market is projected to reach USD 64.61 billion by 2030, growing from USD 31.35 billion in 2025, with a CAGR of 15.56%. Growth is driven by demand for high-resolution, energy-efficient displays in consumer electronics, AR/VR, and automotive sectors.
- PMOLED: Estimated to reach USD 3.42 billion in 2025, with projections of USD 24.41 billion by 2037, reflecting a CAGR of over 17.5%. This growth is fueled by strong demand for cost-effective, energy-efficient display solutions in industrial applications, wearables, and automotive dashboards.
