In many cases, damage that has already occurred can't be reversed, making early detection important. He says that the physiology of the human retina is such that there must be at least 477 pixels per inch in a pixelated display for the pixels to become imperceptible to the human eye at a distance of 12 inches (305mm). Inner segment / outer segment layer – inner segments and outer segments of rods and cones, the outer segments contain a highly specialized light-sensing apparatus.

Retina display? Apple’s screen tech explained What is a Retina display? Apple’s screen tech explained

The further your eyes are from the screen, the lower the pixel density needed to make the pixels ‘disappear’. The Retinome – Defining a reference transcriptome of the adult mammalian retina/retinal pigment epithelium".Based on a drawing by Ramón y Cajal, 1911) Illustration of the distribution of cone cells in the fovea of an individual with normal colour vision (left), and a colourblind (protanopic) retina. In the sheltered environment of the retina, AAV vectors are able to maintain high levels of transgene expression in the retinal pigmented epithelium (RPE), photoreceptors, or ganglion cells for long periods of time after a single treatment. Retina is a trademarked term that refers to any IPS LCD or OLED display with a pixel density high enough that Apple has determined that your eyes won’t be able to make out those pixels at a certain viewing distance. At the centre of the macula is the foveal pit where the cones are narrow and long, and arranged in a hexagonal mosaic, the most dense, in contradistinction to the much fatter cones located more peripherally in the retina. The sort of rich, data-dense information design espoused by Edward Tufte can now not only be made on the computer screen but also enjoyed on one.

In the retinal ganglion cells there are two types of response, depending on the receptive field of the cell. The fovea contains only cone photoreceptors and is the point in the retina responsible for maximum visual acuity and color vision.The scale factor is tripled for devices with even higher pixel densities, such as the iPhone 6 Plus and iPhone X. Retinal Microvascular Responses to Short-Term Changes in Particulate Air Pollution in Healthy Adults". The retina is the light-sensitive layer of cells at the back of the eye that converts light into electrical signals. This matters because the defining characteristic of a Retina Display is that the human eye can't distinguish the pixels. This is the first all-screen LCD in an iPhone and – unlike most ‘bezel-less’ Android phones – Apple has managed to avoid a thick bottom bezel on the iPhone XR (above, left).
