New research could improve efficiency and luminance of TV and smartphone displays

May 16, 2018

BINGHAMTON, N.Y. - Your TV and smartphone could be more efficient and luminescent thanks to new research conducted with assistance from Binghamton University, State University at New York.

When it comes time to buy something like a new TV, the casual consumer will be focused on the size of the screen, while more tech-savvy consumers are interested in knowing things like if the display is LCD or OLED. Put simply, these display technologies determine the quality of the picture on the screen for not just TVs but also for smartphones, computers and tablets. While the market is currently dominated by LCD, both OLED and LCD use what are called thin-film transistors (TFTs).

"While the research provides a way to improve the quality of displays and lower cost, it can also improve the production of electronic devices like solar cells," said Tara Dhakal, director of Binghamton University's Center for Autonomous Solar Power (CASP).

These TFTs are typically produced using one of three processes: amorphous silicon (a-Si:H), low-temperature polysilicon (LTPS) or Indium Gallium Zinc Oxide (IGZO). But a paper titled "High mobility crystalline silicon film growth below 600 °C from an Au-Si eutectic melt for TFTs,"published in Materials Letters, suggests an opportunity to replace these processes, including the most popular process, LTPS, entirely.

The technology was invented by the late Praveen Chaudhari, materials physicist and recipient of the U.S. National Medal of Technology. Ashok Chaudhari, CEO of Solar-Tectic LLC, and Ratnakar D. Vispute of Blue Wave Semiconductors, Inc. oversaw and made the samples, exactly following P. Chaudhari's recipe (now patented), which were then tested by CASP.

Dhakal worked on the study as part of a partnership between businesses and Binghamton University called the Strategic Partnership for Industrial Resurgence (SPIR). His graduate student Pravakar P. Rajbhandari was involved in the characterization of the silicon film provided by Solar-Tectic LLC.

#509 Anisogamy: The Beginning of Male and Female
This week we discuss how the sperm and egg came to be, and how a difference of reproductive interest has led to sexual conflict in bed bugs. We'll be speaking with Dr. Geoff Parker, an evolutionary biologist credited with developing a theory to explain the evolution of two sexes, about anisogamy, sexual reproduction through the fusion of two different gametes: the egg and the sperm. Then we'll speak with Dr. Roberto Pereira, research scientist in urban entomology at the University of Florida, about traumatic insemination in bed bugs.
