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.
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.
The PSP was designed by Shin'ichi Ogasawara (小笠原伸一) for the Sony Computer Entertainment subsidiary of Sony Corporation.Early models pre-installed with 1.xx firmware were made in Japan but in order to cut costs, Sony has farmed out PSP production to non-Japanese manufacturers, mainly in China for units pre-installed with firmware version 2.00 and above.

The disc tray, logos, and ...
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.
