A screen in F.lux's "darkroom mode" On installation, the user can choose a location based on geographic coordinates, a ZIP code, or the name of a location. The program then automatically calibrates the device display's color temperature to account for time of day, based on sunrise and sunset at the chosen location. At sunset, it will gradually ...
The display has brightness of 350 nits. This hinge, along with Windows 8, allows the Twist to serve as both a laptop and a tablet. A lock button at the bottom of the screen allows users to override the built-in accelerometer. The Twist does not have a discrete graphics processor; its display is powered by Intel's HD 4000 integrated graphics ...
Electro-optical sensors are used whenever light needs to be converted to energy. Because of this, electro-optical sensors can be seen almost anywhere. Common applications are smartphones where sensors are used to adjust screen brightness, and smartwatches in which sensors are used to measure the wearer's heartbeat.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
Dimming the brightness on your cellphone's screen is an effective way to conserve battery life. Since the screen is one of the most power-hungry features on your phone, it can consume a ...

High brightness sunlight readable monitors are typically used commercially in kiosks, vending systems, pipeline inspection systems, outdoor digital signage and advertising, in sports stadiums, in military vehicles, on ships for navigation systems, on bus and train platforms, and much more.
The contrast seeker is a simple device that can be implemented using basic analog electronics. It first uses some form of automatic gain control to adjust the image brightness until it contains some areas with high-contrast spots. This produces a bias voltage signal to represent the background brightness level, making brighter objects stand out.
