Innovation in the display tech sector may get a big boost from research in the area of optically rewritable liquid crystal display (ORWLCD). Current LCD techs are huge battery drainers, but if the pace of research continues the battery-killer will be laid to rest thanks to ORWLCD.
LCD display use liquid crystal molecules that are squeezed between two polarized glass panels, and current are passed through electrodes to influence molecules’ positions and the way it interacts with polarized light. The beauty with ORWLCD, however, is that electrodes aren’t required so power requirements are significantly less. An image is transferred to the ORWLCD display using a quick flash of light, and no power is required to keep the image going.
While refresh rate and color are still limitations for “bi-stable” displays, the recent research in ORWLCD has practical application in producing 3D images. Movies that appear 3D-ish are just the same shots filmed at different angles and then pieced together to trick our eyes. Along that same line, Abhishek Srivastava and his colleagues have devised a method for manipulating images on ORWLCD appear three-dimensional.
To produce a 3D image on an ORWLCD, the team divided an image into three zones—two zones twisted to the left and right by 45 degrees, and one unmodified—and then passing it through a special filter. As it passes through the filter, the light from the three zones swing in different directions, which can then be interpreted as 3D when viewers put on the appropriate spectacles.
The researchers admit that they’re still working on adding color to their display tech as it currently only displays images in greyscale. Moreover, the refresh rate is nowhere near acceptable for movies. Despite these limitations, Srivastava and his team are working diligently to optimize their display tech to fit consumer needs. *So until then, we’ll all have to deal with juice-hogging displays on our phones, wearables and*laptops.
