This document discusses transparent electronics. Transparent electronics are materials that are both optically transparent and electrically conductive. Common transparent conducting oxides used include indium oxide, zinc oxide, and cadmium oxide. These materials can be fabricated using methods like sputtering, vacuum evaporation, chemical vapor deposition, and pulsed laser deposition. The document describes applications for transparent electronics such as transparent thin film transistors, UV detectors, and OLED displays. Advantages include flexibility and reduced costs, while disadvantages include shorter lifetimes and higher manufacturing costs compared to traditional electronics.

I think it will help the beginners who are much not aware of this topic.This is a complete presentation about organic electronics.That have contain all the topics which i think would be very helpful mostly for engineering students and there are many pictures and no names in the slides so students can easily download it and paste it for their college presentation.
This is an effective method of solving energy crisis in a low cost method other than photo-voltaic cell. This DSSC are more efficient and economic than traditional solar cells
Can we just imagine of having a TV which can be rolled up? Wouldn’t you like to be able to read off the screen of your laptop in direct sunlight? Your mobile phone battery to last much, much longer? Or your next flat screen TV to be less expensive, much flatter, and even flexible? Well, now it is possible by an emerging technology based on the revolutionary discovery that, light emitting, fast switching diode could be made from polymers as well as semiconductors.OLED
organic electronics & it's application (OLEDs and it's types) difference between OLEDs, LCD and LED. How OLEDs leads the other lighting or display devices.

Transparent electronics is an emerging science and technology field concentrates on producing ‘invisible’ electronics circuit and optoelectronics devices. The application contains consumer electronics such as automobile windshield, transparent solar panel, transparent display and real time wearable display. In the conventional Si/III-V based electronics, the structure is based on semiconductor junction & transistor. However, the basic building material for transparent electronic devices which is to be transparent and in visible range is a true challenge. Therefore, to understand and implement such technology there are two scientific goals, to have a material which are optically transparent and electrically conductive and to implement an invisible circuitry. Development of such invisible transparent electronic devices needs expertise together from pure and applied science, material science, chemistry, physics &electronic science.
Organic Light Emitting Diode or OLED
An OLED is a solid state device or electronic device that typically consists of organic thin films sandwiched between two thin film conductive electrodes. When electrical current is applied, a bright light is emitted. OLED use a carbon-based designer molecule that emits light when an electric current passes through it. This is called electrophosphorescence. Even with the layered system, these systems are thin . usually less than 500 nm or about 200 times smaller than a human hair.
Transparent Electronic PPT
Transparent electronics is an emerging science and technology field focused on producing ‘invisible’ electronic circuitry and opto-electronic devices. Applications include consumer electronics, new energy sources, and transportation; for example, automobile windshields could transmit visual information to the driver. Glass in almost any setting could also double as an electronic device, possibly improving security systems or offering transparent displays. In a similar vein, windows could be used to produce electrical power. Other civilian and military applications in this research field include realtime wearable displays. As for conventional Si/III–V-based electronics, the basic device structure is based on semiconductor junctions and transistors. However, the device building block materials, the semiconductor, the electric contacts, and the dielectric/passivation layers, must now be transparent in the visible –a true challenge! Therefore, the first scientific goal of this technology must be to discover, understand, and implement transparent high-performance electronic materials. The second goal is their implementation and evaluation in transistor and circuit structures. The third goal relates to achieving application-specific properties since transistor performance and materials property requirements vary, depending on the final product device specifications. Consequently, to enable this revolutionary technology requires bringing together expertise from various pure and applied sciences, including materials science, chemistry, physics, electrical/electronic/circuit engineering, and display science.
TECHNICAL REPORT ON OLED TECHNOLOGY
Self-emissive organic light-emitting diodes (OLEDs) are a new promising technology with high expected profitability on the display market, which is currently dominated by liquid crystals. They show low driving voltages in combination with unrestricted viewing angles, high color-brilliance, light weight, small film-thicknesses and low production costs.
