A bright dot defect or hot pixel is a group of three sub-pixels (one pixel) all of whose transistors are "off" for TN panels or stuck "on" for MVA and PVA panels. [2] This allows all light to pass through to the RGB layer, creating a bright pixel that is always on. Another cause of bright dot may be the presence of impurities in the liquid crystal.
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.
The pixels on OLEDs inevitably lose their brightness over time. The longer an OLED pixel is used (illuminated), the dimmer it will appear next to a lesser-used pixel. [6] In the case of LCDs, the physics of burn-in are different than plasma and OLED, which develop burn-in from luminance degradation of the light-emitting pixels.
Three distinct types of defective pixels are described: Type 1 = a hot pixel (always on, being colour white) Type 2 = a dead pixel (always off, meaning black) Type 3 = a stuck pixel (one or more sub-pixels (red, blue or green) are always on or always off) The table below shows the maximum number of allowed defects (per type) per 1 million pixels.

Messing up pronunciations can be a source of both annoyance and amusement, but language learning platform Babbel has put together a handy guide to stop you putting your foot in it.
In a Facebook post Tuesday night, the George County Sheriff's Office urged the public to be cautious. "He will be desperate and very very dangerous. Call your family and alert them. Send messages ...
Fixed pixel displays are display technologies such as LCD and plasma that use an unfluctuating matrix of pixels with a set number of pixels in each row and column. [1] [2] With such displays, adjusting to different aspect ratios because of different input signals requires complex processing. [2] [better source needed]
