屏幕刷新率与运动模糊感知

A screen's refresh rate measures how many times per second it redraws the image.
Standard monitors refresh at 60 Hz, while gaming displays often reach 144 or 240 Hz.
Low refresh rates cause visible 'motion blur' when fast objects move across the screen.
This happens because the human eye retains images briefly, blending successive frames.
Higher refresh rates reduce blur by updating positions more frequently and smoothly.
Response time — how quickly pixels change color — also affects perceived sharpness.
Smartphones use adaptive refresh rates to save battery while maintaining clarity.
Video content filmed at 24 or 30 fps may still look smooth on high-Hz screens due to interpolation.
VR headsets require at least 90 Hz to prevent nausea from lag-induced disorientation.
Refresh rate matters most in dynamic tasks like gaming, sports viewing, or drone piloting.

Smartphones use adaptive refresh rates to save battery while maintaining clarity. 智能手机采用自适应刷新率，在保证清晰度的同时节省电量。
This happens because the human eye retains images briefly, blending successive frames. 这是因为人眼会短暂保留图像，使连续帧相互融合。
Higher refresh rates reduce blur by updating positions more frequently and smoothly. 更高的刷新率通过更频繁、更平滑地更新画面位置来减少模糊。
