What is TOLED?
TOLED is the acronym for Transparent Organic Light-Emitting Device, a type of organic optoelectronic device similar to OLEDs (Organic Light-Emitting Diodes). This is a new technology for displays, lighting and other applications that can be made thinner, lighter and more energy efficient than traditional LED or LCD displays.
How does TOLED work?
TOLED works by combining two layers of organic materials – a thin film of organic semiconductors and a transparent layer of anode and cathode electrodes – to create an electric current when a voltage is applied. This current passes through organic materials, which consequently emit light.
TOLED applications
TOLED can be used in a wide range of applications, from displays to lighting, medical imaging to augmented and virtual reality. It is used to create thinner, lighter and more energy-efficient displays and lighting, as well as devices that can be embedded in objects or even worn as clothing.
Advantages and disadvantages of TOLED
TOLED offers a number of benefits, including thinner and lighter displays, higher contrast and color accuracy, greater energy efficiency, and a longer lifespan than traditional LED or LCD displays. However, this is still a relatively new technology and its cost and limited availability may represent a limitation.
The TOLED market
The TOLED market is expected to grow rapidly in the coming years, driven by growing demand for thinner, lighter and more energy-efficient displays and lighting. The global TOLED market is estimated to reach $1.6 billion by 2026.
Companies that develop TOLED
Several companies are currently developing and manufacturing TOLED displays and lighting, including Samsung, LG, and Sony, as well as smaller companies such as Universal Display Corporation and AU Optronics.

Types of TOLED
TOLED displays and lighting can be divided into two main types: small molecule TOLED and polymer TOLED. Small-molecule TOLEDs are made with small molecules, while polymer TOLEDs are made with polymers. The two types differ in terms of cost, efficiency and durability.
TOLED manufacturers
Several companies currently produce TOLED displays and lighting, including Samsung, LG, Sony and AU Optronics. These companies use different technologies, such as inkjet printing, vacuum deposition, and chemical vapor deposition.
Challenges in TOLED development
Despite the advantages of TOLEDs, there are still several challenges to address before they can be widely used, including cost, efficiency and durability. Researchers are working to develop new materials and processes to improve the performance of TOLED displays and lighting.
