Motion Blur in Monitors

Sammanfattning: The purpose of this essay is to analyze different monitor types and whymotion blur appears with moving pictures. The CRT monitors who no longerare produced due to their old age and ancient technology have a little to nomotion blur at all while modern monitors like the LCD monitor usually havea lot. What makes the CRT so much better at handling moving picturesthan the LCD is that the CRT monitors have a flickering image, making themovement appear more natural to the eye. LCD monitors have a continuousimage with long persistence which is hard for the eye to follow, and in additionto that the pixels on an LCD take longer time to adjust after each framewhich contributes to the blurry image. These problems are also referred to assample and hold and ghosting. To fix this the light given to the pixels shouldbe strobed, shortening persistence and making the object easy to follow. Dueto these problems, a well suited LCD monitor from ViewSonic, ViewSonicXG2431, were found and tests were made on it to see if it could replace theCRT monitor. The CRT monitor still outperformed the ViewSonic monitorwhen motion blur was analyzed, but the ViewSonic XG2431 showed promisingresults.
