small OLED display for biomedical field

Over the years, we have seen OLEDs used to create digital displays on devices like television screens, computer monitors, smartphones, and other devices. Undoubtedly, they are currently one of the most advanced display technologies, and OEMs primarily use them in their flagship smartphones. This versatile technology has a wide range of applications, and today we will be exploring how small OLED display is used in the biomedical field.


What Is a Small OLED Display?

The acronym ‘OLED’ stands for Organic Light-Emitting Diode, a technology that uses LEDs to produce light from organic molecules. The small OLED display is built on a very thin substrate, allowing for a thinner and more flexible display while having the highest possible image quality. The small OLED display is the industry leader in display technology for wearable devices such as smartwatches, home appliances, and many others.


Benefits of OLED Displays

Recently, OLED has been outperforming other displays. The small OLED display is used to make what is regarded as the best display panels in the world, and they have numerous unique benefits to offer to the consumers, such as:

  • Self-Emitting

Because of its organic material, the OLED display is self-illuminating, i.e., images are generated by themselves. Unlike LCDs, they do not require an external light source to display an image.

  • Compact

The small OLED display is more compact and robust. Small OLEDs are a thinner version of a display screen made of the same crystalline layers used in LCDs and LEDs, and the thickness of the display ranges between 2mm and 4mm.

  • Flexible

Some small OLED displays are incredibly flexible and can be bent without breaking. The panels are lightweight and are built on a flexible foundation made of a long-lasting material such as plastic, metal, or even flexible glass.

  • Low Energy Consumption

OLED displays are one of the most energy-efficient of all display types. They use less power than LED displays and do not require a backlight, making themselves perfect for battery-powered devices.

Applications of Small OLED Displays in the Biomedical Field

  • Small OLEDs for Lab-On-Chip Applications

Over the last few decades, progressions in OLED displays have created new opportunities for compact and low-cost lab-on-chip sensors. Because of the use of small molecules in OLED, they are more efficient for lab-on-chip applications. They are used for outpatient and at-home testing of patient samples in the food and agriculture industries, as well as the chemical industry.

As they have the ability to significantly lower manufacturing costs and reduce negative environmental impact, they are considered essential for single-use sensors deployed in situations where adequate waste disposal may not be available.

  • Wearable OLEDs for Health Monitoring

Small OLED displays are now being produced to meet the growing demand for more compact biocompatible devices that can be implanted in wearable devices for patients. They are part of the devices such as smartwatches and activity trackers that allow continuous monitoring and treatment for patients with various ailments.

The pulse rate can also be calculated by using OLEDs to detect reflected light from blood vessels. Moreover, the appropriate bright light delivers light to previously “dark” areas, leading to a more “invisible” form of biophotonics.

  • OLEDs for Therapeutic Treatment

PMOLED is also used as a therapeutic light source, which is ideal for outpatient care. Small OLEDs are embedded in plasters and worn directly on the skin as point-of-care biomedical devices. They are primarily used in photodynamic therapy (PDT) and photo biomodulation in the biomedical field (PBM).

Not only this, but wearable OLED patches can also be attached to the skin in PDT to treat cancer. On the other hand, PBM refers to using low-intensity light from small LEDs for therapy, such as accelerating wound healing, reducing inflammation, or relieving pain.

  • OLEDs for Optogenetics

Optogenetics is a scientific biological technique that uses light to control the activity of neurons or other cell types. This is why their power density uses highly optimized and robust OLED structures. They are commonly used in biomedical devices to control the membrane current in a mammalian cell line optically (HEK cells). PMOLED
