Claim Text:
1. A method for measuring the response time of an LCD, comprising the following steps: step A: the LCD displaying a preset image in a controlled manner; step B: obtaining a first and second luminance values of the LCD when displaying the preset image, and outputting a luminance-time curve in which the second luminance value changes over the time; wherein, the first and second luminance values are respectively measured by a standard luminance measuring device and an actual luminance measuring device, the standard luminance measuring device is configured to measure a luminance-gray scale characteristic of the LCD, and the actual luminance measuring device is configured to measure a luminance-time characteristic of the LCD; and step C: correcting the luminance-time curve to obtain a corrected luminance-time curve by replacing the second luminance value in the luminance-time curve with a corrected luminance value, and calculating the response time of the LCD according to the corrected luminance-time curve; wherein the corrected luminance value is obtained with the following steps:
