Applications and Future Developments of Flexible Organic Light-emitting Diode

Abstract

With the rapid development of display technology, human beings have more and more stringent requirements for display products, e.g., their light weight, thinness, flexible performances, and versatility. Contemporarily, the flexible organic light-emitting diode (OLED) technology and its derived multi-layer structure tend to be wearable, light, and responsive in a short time. Although flexible OLED technology is popular, there are still many problems that needs to be addressed, e.g., new raw materials, rough flexible substrate, and low efficiency in workmanship, resulting in poor luminescence, rough and inflexible products. In this paper, a new type of flexible fiber display system is proposed by combining OLED with conductive optical fiber. This paper comprehensively introduces the mechanism, manufacturing technology and structure of this new type of flexible OLED. It covers various scopes like Internet information communication, real-time positioning, and medical assistance, etc. Despite some challenges and limitations, this product possesses a variety of advantages in terms of its convenience and flexibility, which makes the exploitation of a large range of applications probable. Therefore, it is highly expected that these promising prospects of development will stimulate the further progress in display fabrication, which helps to facilitate people’s lives in the future. These results shed light on the significance of developments of flexible OLED technology.

Inkjet Printing Optimization: Toward Realization of High‐Resolution Printed Electronics

“…The significant growth of OLEDs is driven by their lucrative benefits, such as self‐emission, flexibility, low driving voltage, high response speed, large viewing angle, wide color variations, and low power requirement. [ 179,180 ] OLED is a type of electroluminescent display technology that utilizes organic compounds to emit light when an electrical current is applied. [ 160 ] The selection of materials for the light emitting layer is crucial as its optical and electrical properties will determine the image quality displayed by the OLED.…”

Opportunities for cost-effective manufacturing of fully printed high performance displays enabled by vertical light-emitting transistor pixels

“…Once the manufacturing technology matures, micro-LED displays are predicted to challenge AMOLED's dominant position in the premium display market, especially among products requiring a long lifecycle, such as in vehicle, industrial and commercial display panels, TVs and large home appliances, enjoying the high profit margin which currently belongs to AMOLED [36,37]. At that point, AMOLED, as a mature technology approaching its final steps on its commoditization cycle, can be expected to hold onto a dominant share at the other end of the spectrum in the market, for applications with comparatively shorter lifecycles, such as small handheld devices, small home appliances, and future high volume applications such as display-on-package, wearable displays and disposable electronics [38][39][40][41][42]. The key for AMOLED to ensure such prospective competitiveness will require dramatic reductions in its cost of manufacturing.…”
