lcd screen
Pixel is an important topic when buying laptop LCD screen. Then how to tell the difference between different kinds of pixels?
First, let us start to have some knowledge about what is pixel. A pixel is generally thought of as the smallest single component of a digital image. The definition is highly context-sensitive. For example, there can be "printed pixels" in a page, or pixels carried by electronic signals, or represented by digital values, or pixels on a display device, or pixels in a digital camera (photosensor elements). This list is not exhaustive, and depending on context, there are several terms that are synonymous in particular contexts, such as pel, sample, byte, bit, dot, spot, etc. The term "pixels" can be used in the abstract, or as a unit of measure, in particular when using pixels as a measure of resolution, such as: 2400 pixels per inch, 640 pixels per line, or spaced 10 pixels apart.
Usually standard display resolutions include:
CGA 0.064 320×200
EGA 0.224 640×350
VGA 0.3 640×480
SVGA 0.5 800×600
XGA 0.8 1024×768
SXGA 1.3 1280×1024
UXGA 1.9 1600×1200
