![]() The experimental results show that the natural light stimulation of nanoparticles, in fact, causes the activation of retinal neurons spared from degeneration, thus mimicking the functioning of photoreceptors in healthy subjects. ![]() The 'second generation' artificial retina is biomimetic, offers high spatial resolution and consists of an aqueous component in which photoactive polymeric nanoparticles (whose size is 350 nanometres, thus about 1/100 of the diameter of a hair) are suspended, and will replace damaged photoreceptors. It whined like a b*ch in HGC mode too.The study represents the state of the art in retinal prosthetics and is an evolution of the planar artificial retinal model developed by the same team in 2017 and based on organic semiconductor materials ( Nature Materials 2017, 16: 681-689). The HGC card set you back $500 at the time, equivalent to $1500 today, but fortunately some of the PC clones like mine came with a HGC clone built-in. If you wanted a “high resolution” display a popular upgrade was the Hercules Graphics Card (HGC) and compatible display brought you up to a whopping 720x348 monochrome. My original IBM PC clone had a color graphics card and was typically run in 320x200 pixel mode if you wanted to take advantage of having a whopping 4 colors. Whether it’s laced with marketing speak or doesn’t satisfy scientific scrutiny doesn’t really matter at this point because it’s such a massive improvement over what some of us started with and even the display technologies of the 90s and early 00s. Retina rocks. There is no turning back. Steve Jobs and Apple significantly raised our expectations with Retina for what we should consider to be the standard for comfortable and natural human interaction with computers and displays of every size. Thank you! Very informative and especially liked seeing all of the marketing terms explained in useful detail.Ī lot of current computing device users probably don’t appreciate just how far display technology has advanced in the past 40 or so years. "XDR" - Extreme Dynamic Range a 1,000,000:1 contrast ratio."True Tone" - Dynamic adjustment of the display's brightness and temperature to match the surrounding light. ![]() ![]()
