Response time (Motion)
Response speeds refers to how quickly an image is refreshed. If a display has a slow response rate, fast moving scenes can cause ‘motion blur’ where images lose their sharpness and the picture appears out of focus.
Prior to showing the comparison video sequence, the research team posed the question to the audience that had knowledge of plasma and LCD: ‘Which display is best for response speed?’ The findings are almost equally split, 31 per cent highlighted LCD, 31 per cent selected plasma while 38 per cent indicated that both technologies are equally adept at response rates.
Which display format is the best for response speed?
Plasma flat screen is best for this.
LCD flat screen is best for this.
LCD and plasma are equal for this.
The same question was posed once the participants had seen the film – again recording a significant shift in plasma’s favour with 62 per cent indicating that plasma has the best response time. Support for LCD fell markedly to 22 per cent.
Note: Respondents were given the following explanation for response speed: This is the capacity of the screen to accurately show fast moving images. In cases where the response speed is not optimal one can see ‘after-images’ when fast moving images are shown on screen (also known as ‘ghosts’). As an example, when the response speed is too low, you can not perfectly see the ball while watching a football match on television.
