About the book

Normally, the Light-emitting diodes (LEDs) are fabricated by employing a precise thin layer of profoundly doped semiconductor material and contingent on the semiconductor material used and based on the doping concentration, when forward biased an LED which emits a colored light at a specific spectral wavelength. It works on the electroluminescent principle and can emit light in visible specter as well as in infrared and ultraviolet. They have characteristically low energy consumption, small size, longer lifetime, and faster switching than incandescence lamps and because of that, they have a wide palette of applicability. Over the years semiconductor technology has advanced to bigger heights. The result is what we see around us in the form of smart gadgets. LED or Light Emitting Devices have also been a part of this revolution as any LED is a semiconductor. Now we have LED’s which give better illumination with low power consumption. These LEDs have a better life span too. Certainly, these advancements have lived up to influence the shapes, sizes & even the format of circuit in which an LED can be mounted. So that’s quite sensational. Also, the production of LED encompasses the following such as flexible thin-film LED, Colour capability, Power consumption, Bright images, Wide viewing angle, fast response time, Low cost in the future, Lifespan, Power consumption, UV sensitivity, RoHS manufacturing compatibility (lead-free), Deep UV-LEDs purify water and air using short-wavelength ultraviolet rays, etc. This book would form the basis for a better fundamental understanding of the capabilities and limitations of each category of LED, and may also suggest better, cheaper or alternative lithography technologies to be considered for their applications.

The area of interest and scope of the project can be described with (but are not limited to) the following keywords:
The LED can be lingering further into three major categories are (i) Traditional inorganic LEDs, (ii) Organic LEDs (Small Molecule OLED, Polymer LED, Passive Matrix OLED Active Matrix OLED), (iii) High brightness LEDs, (iv) Deep-UV LEDs, (v) Active Matrix Organic Light-Emitting Diodes (AMOLED).

Introducing your Author Service Manager

Mr. Mateo Pulko

As an Author Service Manager my responsibilities include monitoring and facilitating all publishing activities for authors and editors. From chapter submission and review, to approval and revision, copyediting and design, until final publication, I work closely with authors and editors to ensure a simple and easy publishing process. I maintain constant and effective communication with authors, editors and reviewers, which allows for a level of personal support that enables contributors to fully commit and concentrate on the chapters they are writing, editing, or reviewing. I assist authors in the preparation of their full chapter submissions and track important deadlines and ensure they are met. I help to coordinate internal processes such as linguistic review, and monitor the technical aspects of the process. As an ASM I am also involved in the acquisition of editors. Whether that be identifying an exceptional author and proposing an editorship collaboration, or contacting researchers who would like the opportunity to work with IntechOpen, I establish and help manage author and editor acquisition and contact.
