Description

Test Card is a simple screen test pattern for Android devices written by Ian Cameron Smith (aka headstay) and released under GPL license.

The app displays test patterns which enable you to see the structure of individual pixels, and the effect that has on the overall quality of the display.

On many devices, the display will be utterly uninteresting. However, on some, notably AMOLED devices, the results â€” when viewed under magnification â€” are much more interesting. Comparing a Motorola Droid with a Nexus One, for example, shows a significant difference in the display quality.

The test patterns are shown multiple times at different offsets, so that if a screen has pixels with different colour components â€” as some AMOLED displays â€” you can see how the patterns look on different pixel alignments. On some displays this will have no effect, on others a very marked effect.
