A light sensor is used to detect the level of ambient light and to produce an output signal representative of the detected amount or level of such ambient light. A light sensor includes a light transducer for converting light into an electrical signal and may also include electronics for signal conditioning, compensation for cross-sensitivities such as temperature, and output signal formatting. The produced output signal of a light sensor is used by a wide variety of devices and assemblies, such as display devices, to operationally adjust one or more respective attributes or characteristics of these devices. Under changing light conditions, the user generally has the opportunity to adapt specific operating parameters of the device, such as brightness or contrast, for instance, to the light conditions in the vicinity of the apparatus. Optical light sensors are normally formed as reflection or transmission light sensors.
