A stuck sub-pixel or stuck pixel is a pixel that is always "on". [2] This is usually caused by a transistor that is getting power all the time (VA/IPS) or not getting any power (TN) and is therefore continuously allowing light at that point to pass through to the RGB layer. Any given pixel will stay red, blue, or green and will not change when ...
Image persistence, or image retention, is a phenomenon in LCD and plasma displays where unwanted visual information is shown which corresponds to a previous state of the display. It is the flat-panel equivalent of screen burn-in. Unlike screen burn-in, the effects are usually temporary and often not visible without close inspection.

Choose whether or not to display images in AOL Mail. While the default setting is to show all images except for those in spam emails, turning the setting off can increase the privacy and security of your account by disabling potentially malicious images and content.
In motion compensated video compression, the current picture is predicted by shifting blocks (macroblocks, partitions, or prediction units) of pixels from previously decoded frames. If two neighboring blocks use different motion vectors, there will be a discontinuity at the edge between the blocks.
Do not explicitly define the size of an image in pixels unless there is a good reason to do so. Preferably the size should be specified as a value relative to the user's preferred thumbnail width, using the |upright= scaling factor parameter rather than pixel values, whenever an image is to be displayed at something other than the default width.
