Abstract

A method and system for measuring the response time of a liquid crystal display. The method comprises the following steps: A. displaying a preset image on the liquid crystal display; B. acquiring the brightness of the liquid crystal display for displaying the preset image, and outputting a brightness-time curve of the brightness changing over time; and C. correcting the brightness-time curve so as to acquire a corrected brightness-time curve, and calculating the response time of the liquid crystal display according to the corrected brightness-time curve. The method is beneficial for reducing or eliminating an error of the measured response time due to the fact that a response time measuring system uses measurement devices with different actual brightness.

Description

technical field [0001] The invention relates to the field of liquid crystal display characteristic measurement, in particular to a method and system for measuring the response time of a liquid crystal display. Background technique [0002] LCD response time refers to the speed at which each pixel of the LCD responds to the input signal, that is, the time required for the pixel to turn from dark to bright or from bright to dark. It is an important parameter to measure the performance of the LCD and directly affects the LCD. The quality of the displayed images, especially moving images. Therefore, measuring the response time is a necessary item for liquid crystal display performance testing. Generally speaking, when measuring the response time of most LCD monitors, the response time specified by the 305-1 standard managed by the Video Electronics Standards Association (VESA) is measured by first preset two different gray levels (hereinafter referred to as gray level A and gr...
