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 ]
Varies based on image brightness and color. For the majority of images it will consume 60–80% of the power of an LCD. OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight , [ 35 ] while OLED can use more than three times as much power to display a mostly white image ...
A foot-lambert or footlambert (fL, sometimes fl or ft-L) is a unit of luminance in United States customary units and some other unit systems. A foot-lambert equals 1/π or 0.3183 candela per square foot, or 3.426 candela per square meter (the corresponding SI unit).
Sunlight readable monitors typically provide at least 800 nits of brightness, [1] [non-primary source needed] versus 200–300 nits brightness for a typical desktop computer monitor. [2] Sunlight readable monitors may also be optically bonded.
Minimum: vertical field rate (1–255 Hz; 256–510 Hz, if offset). 6: Maximum 7: Minimum: horizontal line rate (1–255 kHz; 256–510 kHz, if offset). 8: Maximum 9: Maximum pixel clock rate, rounded up to 10 MHz multiple (10–2550 MHz). 10: Extended timing information type: 00 = Default GTF (when basic display parameters byte 24, bit 0 is set).
Luminance is used in the video industry to characterize the brightness of displays. A typical computer display emits between 50 and 300 cd/m 2 . The sun has a luminance of about 1.6 × 10 9 cd/m 2 at noon.
The highlights—the brightest parts of an image—can be brighter, more colorful, and more detailed. [2] The larger capacity for brightness can be used to increase the brightness of small areas without increasing the overall image's brightness, resulting in, for example, bright reflections from shiny objects, bright stars in a dark night scene, and bright and colorful light-emissive objects ...
Mann's HDR (high-dynamic-range) welding helmet augments the image in dark areas and diminishes it in bright areas, thus implementing computer-mediated reality. In the 1970s and 1980s, Steve Mann invented the Generation-1 and Generation-2 "Digital Eye Glass" as a vision aid to help people see better with some versions being built into welding ...
