Tencent Digital (Compile: Guti) According to foreign media reports, recently scientists are developing a new kind of “electronic paper†technology. This “electronic paper†is actually a kind of ultra-thin flexible display with high energy efficiency. Sexuality, and content can be clearly displayed in direct sunlight or in a bright environment. It is reported that the thickness of this kind of flexible display screen is less than 1 micron, and can show the color that all ordinary LED display screens can display, and according to researchers, this display screen consumes more power than Kindle electronic paper book. The use of e-ink screens is much less, only one-tenth.
According to reports, this ultra-thin flexible display is very suitable for displaying information in outdoor public places due to its high brightness. In addition to significantly reducing energy consumption, it can also replace existing signal and information displays and use It is also more flexible.
The head of the study was Professor Andreas Dahlin and Professor Kunli Xiong from Chalmers University of Technology, Sweden, who are trying to incorporate conductive polymers into nanostructures to combine flexible electronic displays that can be as thin as paper. The "electronic paper" is similar to the Kindle tablet computer in its light emitting principle. It is not a standard display screen, but it does not rely on external light sources for illumination.
This kind of display screen and ordinary LED screen are suitable for use in a dark environment, it is more suitable for display in a well-lit environment. At the same time its power consumption is only one-tenth of the Kindle tablet screen, so the energy consumption is naturally lower than the traditional LED display.
This trait depends on the polymer's ability to control and respond to light absorption, and the polymer that covers the entire surface allows the entire electronic signal to form a high-resolution screen to show more. Although this material is not yet ready for practical application, there is already a basis for further research and development. The team has already tested a variety of different pixels. These pixels consist of red, green, and blue, which can compose the colors that all standard LED screens can display.
So far, the results of this research have been very smooth and have been able to cover the screen size of ordinary electronic devices. "Although we are still at a basic level, it is not so far away from the actual application of the product," Dahlin said. However, the only obstacle to this kind of flexible ultra-thin display is the use of gold and silver, so the overall cost is very expensive.
"The surface of the screen is covered with a 20-nanometer thick gold coating, so there is also a certain cost requirement," Dahlin said. “But during the R&D process, there are still many gold elements that are being wasted. In the future, we will find new ways to significantly reduce costs.â€
