Afterimage
After Image is a condition where previous, residual image becomes noticeable on the screen. This phenomenon happens when frames switch on an Plasma Television, the image of the previous frame tends to remain even after the image of the new frame is shown. As a result, when the objects on the screen move rapidly, the previous, residual image becomes noticeable on the screen and ofcourse disturbs new frame.
Bit
A bit is the smallest unit of information handled by a computer. To process information the computer converts information into either ‘0′ or ‘1′ (OFF or ON in terms of electrical flow). The higher the number of bits, the larger the amount of information that can be processed at one time. To process a huge amount of data, such as high-definition image data, the Plasma Television processor should be able to handle a large number of bits.
Brightness
Brightness is the maximum amount of light that can be emitted per unit area. And it is expressed with the unit cd/m2. For display devices, a higher brightness level of Plasma Television means brighter diplayed images.
