(Summary description)The resolution of LCD and CRT displays is much lower than that of paper, and long-term use is extremely tiring. Therefore, in terms of readability of information, electromagnetic display devices cannot replace the status of paper media at all. The two factors that determine the readability of a display device are display brightness and contrast. Display brightness is the luminous flux delivered by the display surface to the observer's eye. For a diffusive display device, the brightness depends on the light generated, while the brightness of a reflective display device depends on the surrounding lighting conditions and the reflectivity of the display device itself, of which the reflectivity of the product is the most critical. Contrast is the ratio of the brightness of white to the brightness of black on a screen, which is one of the reasons why our eyes can distinguish different surfaces. It seems that in order to improve the readability of a display device, it must have sufficient brightness and good contrast.
