Pixel Inversion Test

This page will help test your LED or LCD screen for effects of pixel inversion. Pixel inversion can cause flickering that is visible to some people. For more information, visit the About Pixel Inversion page. As you test for pixel inversion you may notice discoloration due to "crosstalk", where the pixels in one part of the screen affect the pixels in another part of the screen. Watch this video to see flickering caused by pixel inversion as well as crosstalk.


Look at all the images below. They are all static (non-moving) images and each side-by-side image is the same color. One or more images may flicker and/or appear a different color. Once you find an image that flickers, click the "view other colors with this layout" link to see which colors produce flickering on your screen. A few things to note:

Quick test

Green is the color that's easiest to see flickering, perhaps because green is much brighter than red or blue. This section shows all seven pixel inversion layouts with the colors #009F00 (brighter green) and #000000 (black).


Most popular colors test

This section shows 11 other colors that are likely to show flickering. Combined with the seven pixel inversion layouts, that makes a total of 77 pairs of images.

Still not seeing any flickering or just want to explore further? If you're interested in viewing more colors, go to the More Colors page where you'll get a lot more colors and can filter by the pixel inversion patern. If you're interested in experimenting with colors that you can't find on the More Colors page, go to the Custom Colors page.
