Transparent electronics is a emerging technology, which is satisfying the requirements of everything invisible or multi-purpose objects.

Before going further let me give an example:

You are travelling in a car and you want to watch a movie or video play. Now the glass shields ie window panels will turn into a tv screen and this is possible with this technology. This is helpful when the driver can't take away his eyes from road but still want to watch out a map of route. Then front window panel acts display with the help of this tech.

What is Transparent Electronics?

Its just Technology for next generation of optoelectronic devices and employs wide band-gap semiconductors for the realization of invisible circuits. Oxide semiconductors are very interesting materials because they combine simultaneously high/low conductivity with high visual transparency.

How it works?

Transparent oxide semiconductor based transistors have recently been proposed using as active channel intrinsic zinc oxide (ZnO). The main advantage of using ZnO deals with the fact that it is possible to growth at/near room temperature high quality polycrystalline ZnO, which is a particular advantage for electronic drivers, where the response speed is of major importance. Besides that, since ZnO is a wide band gap material (3.4 eV), it is transparent in the visible region of the spectra and therefore, also less light sensitive.

Applications:

They have been widely used in a variety of applications like: 1.antistatic coatings
2.touch display panels
3.solar cells,
4.flat panel displays
5.heaters
6.defrosters
7.optical coatings etc

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.
