The definition of infinite is not my definition, it's the Oxford English Dictionary definition.
The human eye cannot detect an infinite range of light waves only part of the full range, and the full range is not infinite. Simple physics.
Contrast ratio has no meaning other than in the flat panel industry where it only has meaning as a marketing term.
The contrast ratio
is a property of a display system, defined as the ratio
of the luminance
of the brightest color (white) to that of the darkest color (black) that the system is capable of producing. A high contrast ratio is a desired aspect of any display. It has similarities with dynamic range
There is no official, standardized way to measure contrast ratio for a system or its parts, nor is there a standard for defining "Contrast Ratio" that is accepted by any standards organization so ratings provided by different manufacturers of display devices are not necessarily comparable to each other due to differences in method of measurement, operation, and unstated variables.
Manufacturers have traditionally favored measurement methods that isolate the device from the system, whereas other designers have more often taken the effect of the room into account. An ideal room would absorb all the light reflecting from a projection screen
or emitted by a CRT
, and the only light seen in the room would come from the display device. With such a room, the contrast ratio of the image
would be the same as the contrast ratio of the device
. Real rooms reflect some of the light back to the displayed image, lowering the contrast ratio seen in the image.
Static contrast ratio
is the luminosity ratio comparing the brightest and darkest color the system is capable of producing simultaneously at any instant of time, while dynamic contrast ratio
is the luminosity ratio comparing the brightest and darkest color the system is capable of producing over time (while the picture is moving). Moving from a system that displays a static motionless image to a system that displays a dynamic, changing picture slightly complicates the definition of the contrast ratio, due to the need to take into account the extra temporal dimension to the measuring process.
There is no such thing as an infinite contrast ratio in the real world so how could any flat panel display have it?
There is no need for a flat panel to display a light brighter than the human eye can view without damage. It is possible to damage the human eye with an excessively bright light, hence the reason I still say there is no need for a display to be brighter than the ZT if viewed in a darkened room as most videophiles do.
OLED is a great display technology and while I admire it. I don't admire corruption of the English language or ridiculous meaningless techno babble as in "more infinite contrast ratio"
