Lenovo launches new affordable Legion gaming monitor with 320Hz refresh rate - Notebookcheck

The next generation of color e-paper is arriving with a substantial performance leap, as E Ink Holdings unveiled its Kaleido 4 platform with claims of doubled color range, brighter whites, and a refresh rate fast enough to handle video. The Taiwanese display maker announced the technology on October 15, naming Hanvon Technology's M10C II smart notebook as the first commercial device built around the new panel. The upgrade targets long-standing complaints about color e-readers, where text often appears softer and images more washed out than on monochrome screens. E Ink says Kaleido 4 doubles the color gamut volume of its predecessor to more than 40,000 colors, while white reflectance climbs 15 percent and contrast improves by 50 percent. Perhaps most notably for a display category historically constrained by sluggish refreshes, the new panel can play video at up to 18 frames per second.

E-readers offer amazing convenience (thousands of books in a single, lightweight device), and recent models have added color screens. Now, E Ink has announced that an updated color version with major improvements is on its way. Here are the details.

The Amazon Colorsoft, recently updated to its second-gen model, also uses Kaleido 3, but in a customized version designed to improve performance. The new release is Kaleido 4 and aims to address color reproduction and contrast issues, not to mention the speed of page refreshes. "Compared to the previous generation, E Ink Kaleido 4 doubles its color gamut volume to more than 40K, increases white reflectance by 15%, and improves contrast by 50%," the maker of the screen announced. "Additionally, with the introduction of new algorithms, E Ink Kaleido 4 is capable of video playback at up to 18 frames per second (FPS).

Vision has become central to modern robotics, but cameras alone cannot tell a robot everything it needs to know about physical contact. When handling flexible objects, inserting components, or manipulating delicate items, robots need information about forces, slippage, and contact that visual systems may miss. Daimon Robotics wants to provide the infrastructure to help robots develop that capability.
