Abstract
A method of measuring a liquid crystal response speed includes steps of generating a sample pulse having a target voltage level and a variable voltage level that varies according to a response characteristic of a display panel, applying the sample pulse to the display panel, detecting the response characteristic of the display panel by the sample pulse, adjusting the variable voltage level until a desired level of the response characteristic is obtained, and generating modulating data representing the setting of the variable voltage level when the desired level of the response characteristic is obtained.
