Comfortable temperatures can be extended beyond this range depending on humidity, air circulation, and other factors. In certain fields, like science and engineering, and within a particular context, room temperature can mean different agreed-upon ranges. In contrast, ambient temperature is the actual temperature, as measured by a thermometer ...
Operating temperature. An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum ...
Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.
A liquid-crystal display ( LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly [1] but instead use a backlight or reflector to produce images in color or monochrome.
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, [39] while OLED can use more than three times as much power to display a mostly white image compared to an LCD.

Bias lighting. A flat-panel television set with colored bias lighting. Video of a bias lighting system with an LED strip light mounted all around the edges at the rear side of the television set, plus two extra lamps ( sidekicks) below for illuminating a larger area. In home cinema and video editing technology, bias lighting is a weak light ...
A medical/clinical thermometer showing the temperature of 38.7 °C (101.7 °F) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.
Externally, the upper limit of the human body’s thermoneutral zone—the ambient temperature range in which the body can effectively maintain its temperature and equilibrium—likely falls ...
