The two main types of OLED displays are Passive Matrix OLED (PMOLED) and Active Matrix OLED (AMOLED). PMOLED uses a simple driving scheme suitable for small, low-resolution screens, while AMOLED employs sophisticated thin-film transistor (TFT) technology, enabling larger, high-resolution, and power-efficient displays ideal for smartphones and TVs. Also check: Flexible OLED

What Is Passive Matrix OLED (PMOLED) and How Does It Work?

Passive Matrix OLED (PMOLED) uses a straightforward control scheme where each row of pixels is activated sequentially, one at a time. It lacks storage capacitors, so pixels are only briefly lit, requiring higher voltages to maintain brightness. PMOLEDs are best suited for small displays like secondary screens or wearable devices due to their simplicity and cost-effectiveness.
PMOLED technology is simple but has limitations such as lower resolution, slower refresh rates, and reduced power efficiency. Panox Display offers a variety of PMOLED panels perfect for small screen applications that require bright, crisp characters or icons on displays under 3 inches.

How Is Active Matrix OLED (AMOLED) Different and Why Is It Preferred for Large Screens?

AMOLED features a thin-film transistor (TFT) array behind the OLED pixels, with capacitors enabling each pixel to be directly addressed and retain its state between refreshes. This allows high-speed updates, higher resolution, and greater power efficiency, especially important for larger displays in smartphones, tablets, and TVs.
Panox Display specializes in supplying advanced AMOLED screens that support vibrant colors, deep blacks, and fast refresh rates, making them ideal for video playback and interactive applications. AMOLED technology also supports flexible and foldable displays, an innovation leading the industry forward.

Which OLED Variations Are Popular Beyond PMOLED and AMOLED?

Beyond the two main types, OLED displays come in specialized forms:

• WOLED (White OLED): Uses a white light-emitting layer with color filters; popular in large TVs by brands like LG.

• QD-OLED (Quantum Dot OLED): Combines blue OLED light with a quantum dot color conversion layer, used by Samsung for rich colors and brightness.

• Transparent OLED: Displays with see-through panels for use in head-up displays or smart windows.

• Foldable OLED: Flexible OLED screens built on plastic substrates, allowing bending and folding without damage.
  These variations expand OLED applications across industries, a variety that Panox Display supports through custom orders and tailored display solutions.

Why Are AMOLED Displays More Power-Efficient Compared to PMOLED?

AMOLED displays only consume power for lit pixels since each pixel is individually controlled and can be turned off completely, resulting in significant energy savings. The presence of storage capacitors keeps pixels on without constant reactivation, unlike PMOLED, where pixels flash on and off rapidly, wasting power.
The power efficiency of AMOLED makes it ideal for battery-powered devices like smartphones and wearable technology. Panox Display’s AMOLED solutions emphasize this energy-saving advantage while delivering high-fidelity images and longer display lifespans.

How Do the Lifespan and Refresh Rate Compare Between PMOLED and AMOLED?

PMOLED technology inherently has a shorter lifespan due to the higher voltage and constant pixel refreshing required to maintain brightness. It also supports slower refresh rates, limiting its use to static images or simple animations. AMOLEDs offer longer lifespans and faster refresh rates, suitable for video-rich applications and dynamic user interfaces.
Panox Display ensures durability and performance by sourcing OLED components with impressive longevity and refresh capabilities, catering to various industries from consumer electronics to automotive displays.

Can OLED Technology Be Customized for Specific Industry Needs?

Yes, OLED technology is highly adaptable. Panox Display offers tailored solutions ranging from micro-OLEDs for VR headsets to circular OLEDs for smartwatches, and ruggedized industrial OLEDs. Customization in size, resolution, touch integration, and flexibility allows OLEDs to fit distinct market needs across military, automotive, healthcare, and wearable tech sectors.
Their expertise in custom production supports startups and enterprise clients alike, overcoming typical minimum order quantity barriers with agile manufacturing capabilities.
