NEXT GENERATION DISPLAY TECHNOLOGY: TRANSPARENT ORGANIC LIGHT EMITTING DIODES
Abstract
Transparent displays have attracted significant interest as new generation display technology in diverse fields, such as glasses, automotive industries, or military technology applications. These applications need simultaneous projection or display of data and visibility of the surroundings through the device to reach transparent OLED, the colour of the emission layer materials, and the opaqueness of the metal thin film cathodes are the important aspects that have to be addressed. In the last few years, Transparent Organic Light Emitting Diode (TOLED) display got very big attention in terms of developing and improving its transparency to be able to make the background visible to the user as much as possible. In this paper, a review of some studies in the literature about Transparent Organic Light Emitting Diode (TOLED) has been made. Some information about prototype applications and technology has been given. Some factors are affecting by making the vision clear in the TOLED such as; haze, the distance between the TOLED display and the object behind it, illumination, transparency, and contrast. There are also some studies about using TOLED displays in vehicles. It recommended that transparency should be ideal and clear as well for the driver.

YENİ NESİL EKRAN TEKNOLOJİSİ: ŞEFFAF ORGANİK IŞIK YAYAN DİYOTLAR
Özet
Ekran teknolojisinin yeni uygulamalarından birisi olan şeffaf organik ışık yayan diyotlar, başta cam endüstrisi, otomotiv endüstrisi, askeri uygulamaları olmak üzere çeşitli alanlarda büyük ilgi görmektedir. Bu uygulamalarda emisyon katmanı malzemelerinin rengine ve metal ince film katotların opaklığı için cihazdan gelen verilerin eşzamanlı görüntülenmesine ve çevrenin görünürlüğüne ihtiyaç duyulmaktadır. Son yıllarda şeffaf organik işık yayan diyot (TOLED) ekran, arka plan kullanıcı için olabildiğince görünür kılmak için şeffaflığı geliştirme ve iyileştirme açısından çalışmalar yapılmaktadır. Yapılan bu çalışmada, TOLED ile ilgili literatürdeki bazı çalışmaların derlemesi yapılmış ve TOLED’in bazı prototip uygulamaları ve teknolojisi hakkında bilgi verilmiştir. TOLED’in görüş netliğini etkileyen bazı faktörler vardır. Bunlar; pus, TOLED ekran ile arkasındaki nesne arasındaki mesafe, aydınlatma, şeffaflık ve kontrasttır. Araçlarda TOLED ekranların kullanılmasıyla ilgili bazı prototip çalışmalar bulunmaktadır. Bu uygulamalarda ekranın şeffaflığı sürücü için ideal ve net olması gerekmektedir.
