Nanotechnology is revolutionizing the field of electronics, especially computers, telecommunications, and optics. The main aim in this area is to understand nanoscale rules and mechanisms to implement new ICT (Information and Communication Technology) systems that are more economic, portable, and dependable.

Nano-sized particles of carbon like nanotubes and buckyballs are composed of only carbon and are extraordinarily strong. Bulletproof vests made from carbon nanotubes that weigh the same as a regular t-shirt are a prime example that showcases the strength of nanoparticles. The source of this phenomenal strength is the special characteristics of the bonds between carbon atoms. Nano-sized particles of titanium dioxide and zinc oxide are used in many sunscreens to block UV radiation more effectively.

Nanotechnology may offer new ways of working for electronics. The use of this technology improves display screens on electronic devices while reducing power consumption and the weight and thickness of screens.

Communication systems based on nanotechnology are discovering new materials on the nanometer scale expected to play a vital role in future challenges in the field of communication systems such as

  • Devices of ultra-high-speed for long and short-range communications links
  • Power-efficient computing devices
  • High-density memory and logic and ultra-fast interconnect.

The use of molecules, instead of electromagnetic or sound waves, to encode and transmit information is a whole new mode of communication that requires innovative solutions such as molecular transceivers, channel models, or protocols for nanonetworks to make them work.

Application Areas of Nanotechnology in Displays

There are three broad technological areas for grouping the display technologies; electronic paper, organic LEDs, Field Emission Displays, and other devices that are made for displaying the still images. A role is played by the nanofabrication techniques and nanomaterials in all of them.

Quantum Dot LEDs (QLEDs)

The most promising optoelectronic materials of the next-generation displays are the quantum dots as they have remarkable physical characteristics and are both electroactive (electroluminescent) and photo-active (photoluminescent). There is no doubt they will be at the core of next-generation displays. Lower consumption of power, lower cost of manufacturing, longer lifetime, and purer colors are possessed by the QD-based materials, as compared to the organic luminescent materials that the OLEDs (organic light-emitting diodes) utilize.

Quantum dot display another major benefit is that one can get displays of all kinds of sizes, rollable, flexible, and printable because quantum dot displays can be virtually deposited on any substrate. A passive matrix quantum dot light-emitting diode (QLED) display is displayed by the researchers, for instance, completely integrated with the flexible electronics.


OLET gives planar light sources which are capable of being easily integrated into different nature's substrates like paper, plastic, glass, silicon, etc. by utilizing standard microelectronic methods as it is a new and latest light-emission concept. OLETs (Organic light-emitting transistors) are planar, alternative light sources joining the electroluminescent device and thin-films transistor switching mechanism in the same architecture. Therefore, a new era can be opened by the organic light-emitting transistors in organic optoelectronics and they can function as the testbeds for addressing general fundamental photonic and optoelectronic problems.

Organic light-emitting diodes (OLEDs) are extremely valuable for various applications in practical life. The phenomenon that light is emitted by some particular organic materials when they are fed with an electric current is what the OLED (organic light-emitting diode) technology is based on. It's utilized already in small electronic device displays on TV screens, digital cameras, MP3 players, and mobile phones. Making organic large-scale solar cells, windows that can be utilized at night time as light source, and extremely power-saving, bright, and ultra-flat OLED televisions are cheaper and more efficient and effective OLED technologies.

An organic compound's thin film makes up the OLED's emissive electroluminescent layer as compared to the regular LEDs. OLEDs don't need a backlight for functioning and thus need less power for operating, all of which make OLEDs extremely attractive. They can be printed on almost all substrates because they are thinner as compared to regular LEDs. Nanoparticles-based coatings and Transparent electrodes are the areas where the nanofabrication methods and nanomaterials are utilized in OLED manufacturing. Nanoparticles-based coatings are used for protecting the OLEDs from damage from the environment by packing the OLEDs (water for instance). OLED fabrication problems can also be solved by nanoparticle-based deposition methods.

A brand new concept of OLEDs with some nanometer of graphene as a transparent conductor has been recently developed by the researchers, which opened the path for OLEDs' cost-effective mass production on a flexible, low-cost, large-area, plastic substrate which is capable of being rolled up like wallpaper and apply virtually to any place you want. OLED brightness and efficiency are still limited by the photon loss and exciton quenching processes

Electronic paper

Light is reflected like an ordinary paper by the electronic paper, unlike a conventional flat panel display which illuminates its pixels by utilizing a power-consuming backlight. The electronic paper can indefinitely hold images and texts without drawing any electricity, while later allowing the changing of the image. The prime example of the electronic paper category is electrophoretic displays as they can be made on flexible, thin substrates and have a paper-like appearance. There is already commercial usage of the electrophoretic displays, for instance, mostly the displays are white and black in the Sony Reader or the Kindle. The color displays still have some quality and cost problems. It is shown by the researchers of nanotechnology that enhanced electronic ink fabrication technology is provided by the organic ink nanoparticles, leading to an e-paper with a lower cost of manufacturing, good contrast ratio, and high brightness.

Field Emission Displays

Carbon nanotubes are now being used by researchers for creating a new class of low-cost, high-resolution, large-area flat panel displays. According to some researchers, the biggest challenge to the dominance of an LCD in the panel display arena will be the field emission display (FED) technology, which uses CNT (carbon nanotubes) as an electron emitter. They also believe that FED is the technology for wide-screen, high-definition televisions.

In a sense, FEDs are a hybrid of LCD televisions and CRT televisions. They capitalize on the famous cathode-anode-phosphor technology made into the full-sized CRTs by utilizing this with the LCDs' dot-matrix cellular construction. Cold cathodes individually control the electron emitters, organized in a grid for generating the colored light (whereas the field emission doesn't depend on the cathode's heating for boiling off the electrons. The thin panel of the LCDs (liquid crystal displays) today makes the field emission display technology possible, providing a broader field-of-view, giving the CRT (cathode ray tube) displays of today a high image quality, and needing less power as compared to the CRT displays of today.
