Method and Device for Measuring Flicker Value of Liquid Crystal Modules |
摘要 |
A method for measuring flicker value of a liquid crystal module and related device are proposed. The method includes: providing flicker images to a liquid crystal module; applying a measure unit to scan the liquid crystal module to convert luminance of the liquid crystal into voltage signals to obtain analog luminance signals of the liquid crystal module; receiving the analog luminance signals from the measure unit and converting the analog luminance signals of the measure unit into digital luminance signals; performing Fourier transformation of the digital luminance signals to obtain magnitude of specific frequency wave; obtaining flicker value of the liquid crystal module through the magnitude of specific frequency wave. By using the present invention, the common voltage signal applied on the liquid crystal module is adjusted based on the flicker value of the liquid crystal module measured in real time. Therefore quality of liquid crystal module products is raised. |
