OLED (Organic Light-Emitting Diode) is a self-luminous electronic circuit element that uses light generated by the energy loss of an exciton after each electron and hole.

2nd-generation OLED emitters, called phosphorescence OLEDs, dope these emitters with heavy metals (usually iridium) which enables an internal efficiency of up to 100%. As of today, very efficient red and green phosphorescence OLEDs are available on the market and most OLED displays make use of these emitters to create highly efficient emitters.

Companies are now developing next-generation deposition processes to enable more efficient production. One example is ink-jet printing, which makes use of soluble OLED inks that can be deposited using huge printers. This process is faster than the current evaporation process, and has almost no waste of materials. While there are still some challenges to overcome, it is expected that printed OLEDs will start entering the market soon - starting with TVs and monitor panels.

An efficient and long-lasting blue emitter material has proven extremely hard to produce, and companies are still struggling to develop this material. Any much-anticipated success in doing so would surely have a dramatic effect on the power efficiency of OLED displays. One option is to develop a blue phosphorescence OLED. However, in recent years, there has been the development of a 3rd generation of OLED materials - TADF materials that could acheive higher OLED device efficencies. Hyperfluorescence (4the generation) OLED technologies also show great promise.

OLEDs, being a newer entrant in the display market, present challenges in fully assessing their longevity. Continual advancements in OLED technology and the relatively short time since their introduction make it difficult to thoroughly evaluate their performance. Present-day OLEDs are estimated to maintain consistent performance for 100,000 hours with proper maintenance, equivalent to 10 hours a day over 10 years.

The future of OLEDs seems bright as their presence in the smartphone and TV markets is continuously growing, in addition to other markets (such as wearables, VR and more).

The self-emissive OLED is slim and light as it does not require a backlight, liquid crystals, color filters, or other structural components.

Advantages ofOLED

Pixel dimming is a technology that allows every individual pixel to independently darken or brighten the smallest units of the image.

Viewing angles play a crucial role in the overall viewing experience of a screen. When observing a display from an angle, you may notice degradation in image quality, such as washout or shadows. This phenomenon highlights the importance of wider viewing angles, which ensure consistent image quality regardless of the viewer’s position.

Everything from the environment your display will be used in, your budget, to the lighting conditions and the required durability will play a part in this decision.

Testing an OLED device involves simultaneously measuring its electrical and optical properties to generate a current-voltage-luminance (IVL) curve. This allows the power efficiency and brightness to be characterised. Lifetime testing is also important to ascertain how quickly an OLED will degrade over extended use.

Contrast denotes the distinction between the brightest and darkest elements within an image. Higher contrast yields sharper images and ensures legible text, crucial for graphic fidelity and message visibility on displays. Unlike LCDs, which rely on a built-in backlight, OLEDs achieve significantly superior contrast by individually controlling pixels. In OLED displays, when portraying black, pixels deactivate entirely, resulting in vastly enhanced contrast compared to LCDs.

LCDs have a longer history in the market compared to OLEDs, providing ample data to support their longevity. On average, LCDs have demonstrated approximately 60,000 hours (equivalent to 2,500 days) of operational lifespan, translating to around 7 years of consistent performance. While some dimming of the backlight may occur over time, it typically does not significantly impact display quality.

OLEDs are most popularly used to make OLED TVs - some of the world’s top TV panels are produced based on innovative OLED technology. Various TV companies use OLED technologies to produce award-winning premium OLED TVs, including LG, Phillips and Samsung.

Advanced features, material availability, fabrication issues, and the blue pixel problem are among some of the factors that keep the price of OLED technologies so high.

However, it’s crucial to consider OLED’s susceptibility to image burn-in. Prolonged display of static images can result in permanent afterimages on the screen due to the organic material used in these displays. The lifespan of an OLED varies depending on usage, with static image display potentially diminishing longevity compared to dynamic, constantly changing content.

OLEDvs LED

In OLED display screens, each pixel is controlled individually and emits its own light (unlike LCDs in which the light comes from a backlighting unit). This is known as an emissive display. OLED displays deliver great image quality - bright colors, fast motion and most importantly - very high contrast. Most notably, “real” blacks (that cannot be achieved in LCDs due to the backlighting). The simple OLED design also means that it is relatively easy to produce flexible and transparent displays.

The basic OLED structure is simple - an organic emitter placed between two electrodes. But in order to create efficient and long-lasting devices, commercial OLEDs use several intermediate layers, like electron transport and blocking layers. The whole organic stack is placed between the electrodes, and this whole structure is deposited on the substrate (glass or plastic) and the display backplane (driver electronics). Some OLED displays on the market make use of dozens of different layers, one on top of the other.

Foldable smart phones and tablets have been commercially available since 2018, including the Samsung Galaxy Fold and Flip series. As the technology develops, now over 1% of the worlds smart phone devices include flexible OLED technology.

Currently, almost all OLED displays on the market are produced using an evaporation-based process, in which the OLED materials are deposited in a vacuum chamber. This has proven to be a great way to make OLEDs, but the process has its limitations - mainly material waste and high cost.

OLED deposition often needs to be done within an inert environment such as a glove box as these material are quite sensitive. This organic layer is sandwiched between two conductors. When an electrical current is applied, a bright light is emitted. This simple design offers many advantages over other display technologies such as liquid crystal displays. OLED materials are deposited as thin films using a spin coater.

OLED displays, due to their lack of backlight and thinner profile, inherently boast wider viewing angles compared to traditional LCD displays. Images on OLED screens maintain their clarity and readability from almost any viewing position, unlike standard LCDs, which may suffer from distortion and color loss when viewed off-center.

OLEDs are also used in mobile devices - many high-end smartphones use them. For example, Apple's flagship iPhones have featured OLED displays since 2017, which offer vibrant colors and deep blacks. Additionally, the thin and versatile nature of OLED technology has made innovative new designs useful such as the Samsung Galaxy foldable phones.

OLED(Organic Light Emitting Diode) is self-emissive technology. Unlike local dimming technology in LCD, the pixel dimming technology in OLED also enables each pixel to control its brightness independently from other pixel, showcasing perfect picture quality without a halo.
