P‐48: The Selection of Contrast Ratio based on Human Eye's Perception in Actual Use Case

Abstract

Contrast ratio (CR) is an important evaluation parameter for display devices, which can side evaluate the display performance of the display. Through experiments, the ability of human eyes to recognize low grayscale in the actual display scene is studied. Experiments have found that when the background brightness is fixed, the human eye cannot recognize all the low gray scales (CR 2000) of the Panel. In addition, by considering the contrast sensitivity function of the human eye and using psychophysical experiments, we put forward suggestions for the selection of displays in different use scenes.
