HP into developing reflective color e-paper displayBy
Hewlett Packard is well known for is prowess in developing smart computing solutions and has an impressive product range to boast of which range from desktops PCs on the one end to the soon to be released mobile tablet PCs making up the other end of the spectrum with almost every other computing gadget that you can think of making up the rest of the product portfolio. HP is also known for their printers and the excellent quality of their both black-n-white as well as color prints. Everyone thought HP would keep their innovative ideas confined to these products and the most they would stretch themselves, it would be in the tablet PC arena.
But the latest Tablet PC news has come in as a real surprise. For whoever might have thought, HP is also working towards being a credible display centric manufacturer as well. First they announced about their flexible display which was supposed to be an out of the world experience and then there are more recent news of there being yet one more such exotic display, that of Reflective e-paper displays being worked upon by HP. This one is going to use material that provides for brighter yet low power displays that is comparable to E ink with color and a twist thrown in for better effects. The scientists and technological think tanks at HP decided to better upon nature by creating such substances that would use the ambient light to create a more powerful display that would use low power as well.
It can be mentioned here that electronic paper displays continue to be a technological challenge to researchers worldwide. There have been a lot of effort for quite sometime now to create electronic paper that is capable of reflecting light so that there is no need to filter it from a backlight, which is what the majority of conventional displays do. The light reflecting e-papers are soothing to the eye and makes considerable savings on battery power. However, its also here that the main hurdle lies as its simply not easy to create bright, and sharp color display using ambient light. And in order to get around this, HP is looking at developing newer materials which they hope will create a more vibrant and rich color display using natural light. One that will be capable of playing back video in full color while still being easy on the battery.
This is in contrast to the conventional displays like LCDs that relies on backlight in order to produce light along with layers of optics that acts to filter it so as to create different colors. Display of this type require a lot of power since most of the light gets lost during the filtering process.
However, there still is a lot of ground to cover for this technology to reach its feasibility for mass production stages. There have been similar studies like the color e-paper and then Misarol display by Qualcomm, all of which have not seen the light of day as yet. All of the e-paper displays that we have come to see of till now are far too dim and dull compared to conventional displays. So it remains to be seen if HP can break new ground in this aspect.
