Introduction to high-resolution displays

Abstract

Image quality on a display is determined to a large extent by pixel density. The smaller the pixels, the less likely the viewer can perceive pixelation; whereby images become photorealistic and fonts can be formed more perfectly as pixel size decreases. Viewing distance is also a factor when it comes to image quality - as the viewing distance increase, details as fine as pixels become less and less significant. As a result, vision scientists and display engineers have determined “optimal” pixel densities for particular display-related applications. But these calculations tend to be based on visual acuity measuring tools, such as the Snellen visual acuity test - and fail to recognize the ability of the human visual system to discern much finer details. As such, it is predictable that display resolution will be significantly enhanced in the coming years to better match the capabilities of the human visual system.
