A plasma display panel is a type of flat-panel display that uses small cells containing plasma: ionized gas that responds to electric fields. Plasma televisions were the first large (over 32 inches/81 cm diagonal) flat-panel displays to be released to the public.
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.
Other examples: Apple's iPhone X and Samsung's Galaxy series both mitigate or delay the onset of burn-in by shifting the pixels every minute or so for the battery, Wi-Fi, location, and service bars. Also, parallax scrolling may be enabled for the home screen to give icons a 3D-like effect, a setting Apple refers to as "perspective zoom".
Deinterlacing by the display, and telecine processing by studios. These processes can soften images, and/or introduce motion-speed irregularities. Compression artifacts, present in digital video streams, can contribute additional blur during fast motion. Motion blur has been a more severe problem for LCDs, due to their sample-and-hold nature.

Glass display tube is evacuated and carries risk of implosion if improperly handled. May be risky and expensive to repair due to complexity of the display; [47] units with mercury CCFL backlight lamps are an environmental health hazard [48] Screen itself cannot be repaired if the gas used to generate images leaks [49]
Display lag is a phenomenon associated with most types of liquid crystal displays (LCDs) like smartphones and computers and nearly all types of high-definition televisions (HDTVs). It refers to latency, or lag between when the signal is sent to the display and when the display starts

The flicker of a CRT monitor can cause various symptoms in those sensitive to it such as eye strain, headaches [9] in migraine sufferers, and seizures in epileptics. [10]As the flicker is most clearly seen at the edge of our vision there is no obvious risk in using a CRT, but prolonged use can cause a sort of retinal shock where the flickering is seen even when looking away from the monitor.
