ABSTRACT The paper describes a virtual OLED (Organic Light-Emitting Diode) laboratory designed to introduce young people to one of the most contemporary devices and technologies which is heavily used in many gadgets familiar to every teenager. In order to make learning science and engineering fun, such an introduction is made in an interactive multimedia-rich format. In the context of touch screen displays for mobile phones., tablets and TVs, the fundamental principles underlying the design, application, and production of OLEDs and OLED-based devices are demonstrated and explained. The lab enables students to practice preparing an OLED and operating an active matrix OLED (AMOLED) online in a virtual environment.
INTRODUCTION The rapidly evolving OLED is widely used today, appearing in ultra-thin TV screens, touch displays of mobile phones, tablets, and many other gadgets familiar to everyone. OLEDs are also used as military displays due to their flexibility, and as micro displays for gaming visitors due to their lightweight nature and the highly lifelike display quality that they provide. In addition, energy-efficient lighting is another area of OLED applications with a high growth potential. According to market researches [1] OLEDs are expected to form a mainstream market within the next five years in the area of consumer electronics, information technology, and industrial automation. The study [2] reveals that by 2012 cumulative sale of OLED based mobile phone reached 183 million units. The main goal of this virtual OLED laboratory is to introduce young people to this contemporary and very exciting technology and help them understand its benefits and limitations, as well as the underlying concepts and principles behind their operation. In order to make learning more visual and less boring, we want to present information in an interactive multimedia-rich format that today’s students of the digital generation found engaging and that matches their everyday experience and habits in acquiring new information and knowledge. In addition to learning new concepts, students are able to prepare an OLED and operate an active matrix OLED (AMOLED) practice online. The lab is comprised of the following major parts: INTRODUCTION -A video clip that shows various applications of OLEDs in devices like TVs, cell phones, tablets, and flexible displays. Advantages and limitations of OLED vs. LCD and traditional technologies used for the same purposes are explained and discussed;
LAYERED STRUCTURE - A flash simulation that introduces students to a layered structure of an OLED, and then provides them with a task to assemble all of the layers together and explain the functions of each layer; OLED PREPARATION - An online experiment that requires students to prepare a simple OLED, by using virtual materials and tools; OPERATION - Simulations that visualize the physical
