A research team from the Korea Advanced Institute of Science and Technology has developed a technology to create "rainbow particles" that will speed the development of reflective displays. Led by renowned chemical engineering professor, Kim Shin-hyun the research team have developed the particle that is supposed to be vital in the development of next generation displays.

The newly developed particle will allow the development of displays that will project a clearer image under direct sunlight. This can be done by the screen because it can control reflective colors on its own.

This a new breakthrough for the technology as most photonic crystal particles can only display one color which makes it unsuitable for key materials in reflective displays. According to researchers, they deposited two materials with different refractive indexes on sphere shaped fine particles. They succeeded in creating a new particle with rainbow like properties that can reflect any color. Moreover, the team used magnetic fields to check if the particles can display a single specific color.

The team dedicated the research findings to the late professor Shin Joong-hoon who was known as the world's most renowned nano-optics expert. The research findings was published in Advanced Materials on Feb 7.

Technology moves at such a fast pace that components developed this year will soon be outperformed by next generation components. These next generation components can come into production in mere months after its predecessor.

In terms of displays, LCD is the old technology that is surpassed by OLED screens. OLED screens for now are reserved for flagship devices such as the Samsung Galaxy S series of smartphones. Production for OLED screen are still costly and is the reason why only certain phones feature the screen. But it won't be long before every smartphone has an OLED screen as production costs will reduce overtime.

But now a new technology is being developed that will surpass the OLED screens. OLED hasn't been adopted in most devices and we are now seeing signs of better technology. This is a testament to how fast technology advances.
