What is computer screen brightness? Brightness is the setting of the basic light level intensity in a computer monitor. This is commonly set in conjunction with contrast to improve the quality of the viewable image.
What is a candela? The candela is the base unit of measurement of luminous intensity. It is defined as the power emitted by a light source in a particular direction per unit solid angle, weighted by the luminous efficiency function… Read more »
What is a Candela per square meter (CD/M2)? The Candela per Square Meter (also known as a Nit) is the base unit used to measure the luminance of a display. The luminance of a display indicates how of how bright… Read more »
What is a cathode-ray tube (CRT)? A cathode-ray tube (CRT) is a vacuum tube which is used to create images in the form of light emitted from the fluorescent screen. In its simplest form, it contains a source of electrons… Read more »
Contrast is the term used to describe the degree of brightness variation (white through black) in an image.
What does contrast ratio mean? The contrast ratio is a measurement of a display’s contrast capability, and is defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system… Read more »
