Response Time

Response time is how fast a pixel changes state, in milliseconds – e.g. gray-to-gray; shorter times mean less ghosting and motion blur.

Also known as: pixel response time, gray-to-gray, GtG

Response time is a display parameter that defines how quickly a pixel changes its state, typically measured in milliseconds (ms) as the time required to shift from one shade of gray to another (e.g., 0% to 100% and back). Shorter response times result in smoother image transitions and reduced ghosting or motion blur, which is crucial in dynamic applications such as gaming, vision systems, multimedia, or cockpit displays. Displays with slower response times may show delays in refresh or blurred edges of moving objects.
