What are OLED displays?

OLED stands for Organic Light-Emitting Diode. This display technology utilizes organic materials that emit light when an electric current passes through them, allowing for brighter screens. The construction of an OLED display involves placing organic films between two conductors. When electricity is applied, light is emitted, resulting in a simple yet effective design with numerous advantages over traditional display technologies.

OLED displays are emissive, meaning each pixel generates its own light, offering outstanding picture quality. They feature vibrant colors, rapid response times, and, importantly, true blacks. Moreover, the basic design of OLEDs facilitates the creation of flexible displays that can bend and adapt.

1. PMOLED (Passive Matrix OLED)

PMOLED refers to Passive Matrix Organic Light Emitting Diode. While these displays are readily available and less expensive than other LED types, they have a shorter lifespan. Consequently, PMOLEDs are typically employed in smaller devices, usually up to 3 inches.

2. AMOLED

AMOLED stands for Active Matrix Organic Light Emitting Diode. This type of display suits larger screens and includes TFT technology, which further consists of a storage capacitor. Although it operates on the same principles as OLED, AMOLED displays are optimized for better performance.

Advantages of OLED Displays

There are several benefits of OLED technology, including:

• Superior display quality.
• Cost-effectiveness.
• Brighter screens compared to traditional LEDs.
• No need for backlighting.
• Faster response times than standard LCDs.

Disadvantages of OLED Displays

Despite their numerous advantages, OLEDs do have certain limitations:

• OLEDs generally have a shorter lifespan compared to LCDs, LEDs, and PDPs.
• There may be variations in color balance.
• They lack water resistance, making them susceptible to water damage.

What are AMOLED Displays?

AMOLED technology allows for flexible display sizes. It consumes less power compared to other display technologies and offers remarkable performance. AMOLED displays are thinner, lighter, and more adaptable compared to LED or LCD displays.

Thus, AMOLED technology is widely utilized in smartphones, laptops, and televisions. For instance, many Samsung products contain AMOLED displays, such as the Full HD Super AMOLED in the Samsung Galaxy S4 and Note 3.

• Smartwatches
• Tablets
• Portable music players
• Gaming consoles
• Music production hardware
• Digital cameras

Advantages of AMOLED

Benefits of AMOLED technology include:

• Ease of embedding into displays of various sizes.
• Faster refresh rates compared to PMOLED.
• Suitability for industrial applications.
• Better viewing angles compared to IPS LCDs.

Disadvantages of AMOLED in AMOLED vs OLED

AMOLED also presents certain drawbacks:

• Display quality can degrade over time, which is a significant downside.
• AMOLED screens are prone to screen burn-in.
• They are more expensive compared to other display technologies.

Similar protective layers with an additional TFT layer for better performance.

1. Technology - AMOLED vs OLED

The technology behind OLED consists of organic components that emit light upon receiving current. Every pixel emits its own light in OLED technology. In contrast, AMOLED possesses an additional layer of thin-film transistors (TFTs) and storage capacitors that maintain pixel states.

Initially, OLED technology was developed, and while manufacturers may differ in their implementations, Samsung's AMOLED displays utilize plastic substrates with poly-Si TFT technology, similar to LG's POLED. This technology is essential for creating curved displays with an active-matrix OLED panel.

2. Display - AMOLED vs OLED

OLED displays feature deeper blacks than AMOLED screens. Visibility in direct sunlight can be challenging for AMOLED displays. However, AMOLED provides superior display quality due to its additional TFT layer and backplane technologies.

AMOLED screens are significantly more flexible compared to OLED displays, contributing to their higher cost.

3. Working - AMOLED vs OLED

OLED displays are solid-state devices containing a thin layer of organic compounds in an emissive layer, allowing electricity to produce light.

These organic compounds reside between protective glass or plastic layers. In contrast, AMOLED includes an active matrix of OLED pixels along with an additional TFT layer to control current flow, thus enhancing performance.

4. Contrast Ratio - AMOLED vs OLED

OLED displays have excellent control over pixels, allowing them to be completely turned off, which results in a great contrast ratio compared to AMOLED displays. However, AMOLEDs can achieve faster refresh rates and produce a higher artificial contrast ratio since each pixel emits light, albeit consuming more power than OLEDs.

5. Display Size - AMOLED vs OLED

OLED displays are thinner than LCDs, offering efficient and bright visuals. Moreover, they support larger display sizes compared to traditional LCDs, allowing for flexibility in design. AMOLED technology removes display size restrictions, enabling any size to be incorporated smoothly.

Based on the points mentioned, it's important to note that POLED refers to an OLED display utilizing a plastic substrate, while AMOLED is primarily referenced as Samsung's marketing term for its display technology. This compatibility with curved displays arises from the use of a plastic substrate.
