Polymer Organic Light Emitting Diode Materials and Techniques Essay

Polymer Organic Light Emitting Diode Materials and Techniques - Essay Example In the continuously improving and modernizing technological world, one technological discovery is making an important path and giving important contribution in the field of optics. In general, the semi-conducting light-emitting diodes, also referred to as LED, had found vital applications in different technologies through the industrial and modern world. A light-emitting diode can be defined as a semi-conducting diode, which is a form of electronic device that can be considered to maximize the flow of electricity that is flowing through the material and restricting its flow in the other direction such that energy is built up and causes the material to emit light energy. LED can be considered as the general type of diodes that consequently emit light energy. There are different forms of LED (Zheludev 189). A LED can be considered comparatively of more use that other light technology is that it is considered safer on the basis that the main application uses light energy emitting material. This can be attributed to the fact that other forms of light technology through the use of the flow of electric current can be considered more advantageous, often referred to as electroluminescence, which is the basic principle used in LED. Compared to the light technology that uses incandescence, which a process of achieving visible light through electromagnetic radiation (Schubert 1). Due to the said advantage of the technology referred to as LED, the application of the said technology can be considered to continuously increase and improve. In fact the application in technology and other sciences can be considered as widespread. It can be perceived through the different light technologies that are classified as LEDs such as infrared, visible-spectrum, ultraviolet, and white LEDs made from III-V semiconductors. POLED Included in the main types of LEDs is the polymer organic light-emitting diode, referred to as the POLED. The study on POLED can be considered as one of the main area of interest in terms of the types of LEDs. This can be attributed to the fact that the materials used as a semiconductor are organic materials that can conventionally be described for insulation. The application of organic materials for electric purposes can be considered as a relatively new technology since it was only initiated in 1977. The historical discovery of effect of halogen on the electrical conductivity of a polymer paved the way for the continuously growing field of discipline that involves POLEDs (Fung, Lee and Lee 181). Objective of the Study The background information regarding POLED can be considered as one of the reasons that generated the study and attention to the said area in optics. In relation to the increasing assimilated knowledge on the POLED as well as the application and utilization, the study was conducted to be able to present a descriptive and comprehensive presentation of the development of the POLED technology. On the basis of the aim for the public to gain understanding on the application of LED technology, the theory of application is also one of the most important part of the research. Also, the evolution of the POLED tech

Applying Theories and Principles for Planning and Enabling Inclusive Essay

Applying Theories and Principles for Planning and Enabling Inclusive Learning and Teaching - Essay Example The best way to understand Brain-based education is through three words namely: principles, strategies and engagement. Thus, learners have to be engaged and it has to be done with strategies, which are real science based (Darling-Kuria, 2010, p. 02). Brain-based learning effectively ensures to produce a more efficient learning process, which assists the student through comprehension on how the brain delivers, and learns the valuable learning environment possible. Therefore, brain-based learning is the vigorous engagement of strategies that are purposeful on principles, which are effectively derived from neuroscience. Brain-based learning is done in accordance to the way the brain is designed naturally to learn. This study will extensively discuss the various merits of the curriculum, which are taught through instructions, where it is taught, how it taught, the environment, how it measured, and the assessment (Call & Featherstone, 2010a, p.05). A research done recently shows that adul ts have a paramount role in facilitating for the children an early environment that is stimulating. There is therefore a need of the classrooms to have a link that is nearly close to the real-world environment. The curricula being taught should include problem layers, cultural and many sensory layers that effectively stimulate and excite the noble neural networks of the brain. It is also evident that an individual cannot learn in the same way to the other people and thus each individual has his/her own learning style. Evidently, artificial stress on the children is inevitable if the children are forced to learn under ineffective conditions, which greatly interfere with how they learn. These conditions reduce and depress their performance results as well as their motivation. Educators should therefore ensure to embrace the children as individuals and not as a collective class that deserve uniform practices since they are supposed to incorporate diverse teaching skills (Taylor & Macke nney, 2008, p.18). Additionally, educators must provide complex instructions, which effectively enhance and develop learning profiles individually. Complex instruction is multifaceted and it involves providing a variety of resources, groupings, instructional materials, and assessment instruments. Additionally, structured classroom time devoted to emotional and social skill building, group problem solving, and team building strengthens academic learning. Research conducted recently on learning and brain indicates that the brain effectively responds more to learning environments that are enriched and which involve as many of its processing centers as possible. Thus, educators have to allow the children to have rich experiences and then give them time and opportunities to make sense of their experiences by finding and reflecting connections in how things relate to each other. Lessons stimulating emotions, senses, and memory aid cognition and future retrieval in real world situations (C all & Featherstone, 2010b, p.35). The student usually benefits from a type of captivation in which wide selections of motivations are integrated so that the experiences are more genuine and engaging. These experiences should have problem-solving skills in learning different theories and facts since they are personally and meaningfully rewarding to the learners and thus being more inspiring and rewarding. Learners learn
