Shrinking 3-D Touchscreen Films into 2-D Conductive Glasses to Produce Highly Flexible and Printable Screens

A team of researchers from RMIT University has developed an ultra-thin nano-film. This is latest innovation in the field of touchscreens. The ultra-flexible conductive sheets are printable and carries property of rolling out, similar to newspaper.

The ultra-nano-film requires indium-tin-oxide (ITO). The film is shrunk into 2-D from 3-D by applying liquid metal chemistry. The touch-responsive sheet is 100 times thinner than the available touchscreens. Moreover, shrinking the touchscreen into 2-D makes the film more transparent and allows more light through it. Presently used touchscreen is brittle and expensive.

To create atomically-thin-indium-tin-oxide (ITO), the team has taken the approach of liquid metal printing. After heating the compound till 200C, it changes into liquid form. Later, spreading of liquid over a surface provides printable nano-films of indium-tin-oxide.

The 2-D sheets have same chemical composition but different crystal structure from that of 3-D sheets.  The new crystal structure provides new optical as well as mechanical properties to the latest touchscreens

The conductive sheet is highly pliable, hence, roll-to-roll (R2R) process could be used for its manufacturing process. Also, it is compatible with the trending electronic technologies. Further, due to its flexibility property, the conductive sheets absorbed only 0.7% light when compared to standard conductive glass.

Latest Transparent Screen Reduces Power Consumption and High Efficiency

The technology allows twisting and bending. Also, it is more cheap and efficient than that of existing touchscreens.

Overall, integration of the latest touchscreen will reduce the power consumption. Thereby, it will increase the life of battery by approximately 10%.

Further, the technology has wide application in the field of optoelectronic such as touch displays and LEDs. It also holds potential application opportunity in smart windows and solar cells.

Plus point about the technology is easy and cheap manufacturing process. An individual will require cheaper electronics to create printable plastics. The components are easily available in any hardware store.
