Development of 3D Display... Will the Cubic TV Appear?

[Asia Economy Reporter Junho Hwang] Domestic researchers have succeeded in creating a three-dimensional display by folding a display like folding paper. It is expected to enable the realization of double-sided displays with screens on both front and back, as well as TVs with displays on all sides.

Gwangju Institute of Science and Technology announced on the 23rd that Professor Heungjo Ko's research team from the Department of New Materials Engineering developed a display that can output in multiple directions by transforming a flexible electrode-based planar display into a three-dimensional form.

The research team fabricated thin-film electrodes on an acrylonitrile butadiene styrene (ABS) film and then transferred LEDs to create the display. They also selectively deformed the film at desired positions by injecting volatile solvents into nanoscale microfluidic channels that allow fluid flow.

The deformed polymer film does not affect the characteristics of electronic devices even when freely folded inward or outward through plastic deformation. Although it is a planar display device, it can be transformed into various shapes using origami techniques.

The research team stated that the electronic device performance and resolution of the three-dimensional display produced by this method are comparable to those of conventional planar displays, and that it can be manufactured using most existing semiconductor processes.

The team also succeeded in implementing a double-sided display capable of image output on both front and back, a holographic display showing different images depending on viewing angle, and a cube-shaped display capable of output in all directions through the three-dimensional display.

Professor Heungjo Ko said, "The greatest significance of this research is that it presents a technology that allows flexible three-dimensional structural transformation while maintaining the ideal circuit structure that the device should have in the development of three-dimensional electronic devices through deformation of flexible electronic devices." He added, "In the future, we plan to utilize this technology not only for displays but also for the development of various three-dimensional structured sensors, applying it to input/output device development for broadcasting, medical, aerospace, military, advertising, animation, and film industries."
