As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device. The sRGB spec for monitors targets 80 cd/m 2. [3] Typically, monitors calibrated for SDR broadcast or studio color grading should have a brightness of 100 cd/m 2. [4]
An ambient light sensor allows for automatic screen brightness and contrast adjustment, and an RGB sensor enables the adaption of screen colour. Many mobile phones are also equipped with a barometer sensor to measure air pressure, such as Samsung since 2012 with the Galaxy S3 , and Apple since 2014 with the iPhone 6 .
In television sets and computer monitors, the entire front area of the tube is scanned repetitively and systematically in a fixed pattern called a raster. An image is produced by controlling the intensity of each of the three electron beams, one for each additive primary color (red, green, and blue) with a video signal as a reference. [205]
