Wearable devices for a smart society

OLED technology, closely related to OSLD, is growing and expected to see a market size increase. Wearable devices are among its most promising uses. In a future smart society, wearable devices will become crucial in both work and daily life. This society will feature advanced sharing of knowledge and information, leading to overall societal optimization. With the advent of laptops and smartphones, information has become portable and pocket-sized. In this advancing smart society, wearable devices will enable the wearing of information, merging the real and virtual worlds. OLED's thin, light, and flexible properties make it ideal for wearable technology, already being used in VR goggles and smart glasses.

OLED and OSLD have a device structure in common

By applying new materials suitable for lasers to the basic structure of OLED, and introducing a mechanism called a resonator (grating) that has the role of amplifying light, OSLD is realized.

  • SemiconductorSemiconductors are electronic components that control the flow of electricity. Often referred to as the "rice of industry," they are essential in all electronic devices.
    Traditionally, they have been made from inorganic materials like silicon.
  • Organic electronicsWith the advancement of science, semiconductors made from organic materials have become practical. OLED, widely used in smartphones, is one of the most prominent examples of organic semiconductors.
  • LaserThe light emitted by OLEDs is natural light. KOALA Tech is developing devices that produce laser light with high directionality and color purity, based on OLED technology. This is what is known as OSLD.

Towards ideal wearable experiences

KOALA Tech's OSLD provides an essential solution for organic electronics products, including OLEDs, to meet the high performance demands of wearable devices. For example, in smart glasses, there is a need to merge real landscapes with virtual images under the sun. By applying OSLD to the microdisplay, which is the light source technology for smart glasses, optical efficiency is greatly improved, enabling the realization of bright virtual images.
