Replacing Color Filters With Ferroelectric Liquid Crystals, Greatly Reducing Energy Consumption By Nearly 70%
Keda Research Ferroelectric Liquid Crystal replaces color filters and consumes 70% less energy. Many people like to watch movies or episodes on their smartphones, but they consume a lot of power in the process because the built-in color filters consume a lot of energy. The research team of the Hong Kong University of Science and Technology has developed a new generation of liquid crystal displays by replacing the color filters with ferroelectric liquid crystals, which has greatly reduced energy consumption by nearly 70%, while improving triple resolution and low cost. With the support of the Science and Technology Bureau, the research team spent 1 million yuan on project research in two years. Now it is working with several production companies and plans to launch products within one year to facilitate users to buy in the market.
The technology, called "Active Driven Ferroelectric Liquid Crystal Display", was developed by the Electronics and Calculator Engineering team. They jointly built prototypes of this technology with Taiwan and won the best exhibits in the International Information Display Society Innovation Competition. prize.
Lower cost, resolution is tripled
Guo Haicheng, a professor of the Department of Electronics and Computer Engineering at HKUST, said that the new generation of liquid crystal displays is the same size as the conventional ones, but at a lower cost because the color filters in conventional liquid crystal displays account for about 30% of the overall cost. The reaction time of ferroelectric liquid crystal is one thousand times faster than that of color filter, which greatly reduces energy consumption by nearly 70%, and the color sub-pixel of the new liquid crystal display has been removed, so the resolution is also increased by three times. The research team also uses "RGB LED" as the backlight system for the new liquid crystal display. Because the "RGB LED" spectrum is narrower, its color gamut is wider, so the color saturation is improved compared with the traditional.
The research team was awarded a state-funded RMB 1 million through the “Hong Kong, Macao and Taiwan Science and Technology Innovation Cooperation Key Project”. In the future, it will deepen the research on transparent semiconductors and play videos on glass screens to further optimize electronic technology.
