Paving the Way to Next Generation Display
A new type of LCD that does not require polymer orientation films has been developed by researchers within the country. This technology will enable the creation of thiner and higher definition display.
Prof. Hee Tae Jung form KAIST’s biochemical engineering department led the research and Hyun Soo Jung, Hwan Jin Jeon doctoral students (1st co-authors), Doctor Yun Ho Kim from Korea Chemistry Research Center, and Prof. Shin Woong Kang from Jeon Buk University ( co-author) have participated in this research. This research has been funded by the WCU program and middle-grade researcher support program. The results of the research has been published as the online update of ‘‘Nature Asia Materials(NPG Asia Materials)” which is a sister magazine of the world renowned academic magazine ‘Nature’.
The flat display industry is the core industry leading the 21st century’s IT industry. The LCD is the main area of research. Korea is the leader of this industry, holding more than 50% of the world market. Many technologies are combined to make the electro-optic devices of the LCD function. The most important technology, which determines the indicating element’s quality and function is the technology to align the liquid crystals in one direction.
Currently, all LCD products are created by mechanically cutting into the surface of the polymer film and orienting the liquid crystal material along these cuts. However, the creation of polymer orientation films cost much time and money, and the high temperature processes necessary to stabilize the polymers does not allow for the free selection of circuit boards, and thus does not allow for the use in flexible display.
Prof. Hee Tae Jung devised a method to orient liquid display without the use of a polymer film using ITOs. Prof. Jung’s base technology has been tested on ITOs to maintain the necessary transparency and conductivity after forming a pattern with high decomposition rates and slenderness ratios.
The technology developed by the research team can horizontally or vertically align the transparent conductors without the use of polymer orientation films. Thus, the manufacturing processes have become much shortened and the LCDs can be made in much thinner from a few micrometers to a few centimeters. Also, it has a lower functioning voltage and faster response speed, showing the prospects of a high definition ultra-fast screen display development. Furthermore, this technology can be used for any type of board, and can be adjusted to a nanometer scale. This enables for its use in LCD based flexible or multi-domain modes.
Also, the transparent conductor patterning technology devised by the research team can be used not only for displays, but also for touch panels with highly increased sensitivity.
Prof. Jung said, “It was a long desire of the industry and academia to find a way to replace the polymer orientation film. This new technology does not need any polymer orientation films, and we can still use the original boards used for LCDs. This mean a lot to the industry. Also, this technology will increase the sensitivity of the touch panels for tablet PCs and smart phones. It can be used in many areas of future electronics base technology.”

Quantum Mechanical Calculation Theory Developed
An Electron Density Functional Calculation Theory, based on the widely used quantum mechanical principles and yet accurate and with shortened calculation period, was developed by Korean research team.
*Electron Density Functional Calculation Theory: Theory that proves that it is possible to calculate energy and properties with only simple wave equations and electron densities.
The research was conducted by Professor Jeong Yoo Sung (Graduate School of EEWS) and Professor William Goddard with support from WCU Foster Project initiated by Ministry of Education, Science and Technology and Korea Research Foundation. The result was published in the Proceedings of the National Academy of Sciences Journal.
The research team corrected the error when performing quantum calculations that arises from the length of calculation time and incorrect assumptions and developed a theory and algorithm that is more accurate and faster. The use of wave equations in quantum mechanical calculations results in high accuracy but there is a rapid increase in calculation time and is therefore difficult to implement in large molecules with hundreds, or thousands of atoms. By implementing a low electron density variable with relatively less calculation work, the size of calculable molecule increases but the accuracy decreases.
The team focused on the interaction between electrons with different spins to improve upon the speed of calculation in the conventional accurate calculation. The team used the fact that the interaction between electrons with different spins increases as it comes closer together in accordance with the Pauli’s Exclusion Principle.
In addition the interaction between electrons are local and therefore can ignore the interactions between far away electrons and still get the total energy value. The team also took advantage of this fact and developed the algorithm that decreased calculation time hundredth fold.
Professor Jeong commented that, “So far most of the domestic achievements were made by focusing on integrative researches by calculation science and material design communities but these involved short time frames. In areas that required lengthy time frames like fundamentals and software development, there was no competitive advantage. However this research is significant in that a superior solution was developed domestically”.
