摘要： A system and method calibrating operational characteristics of a device. Commands for operation of the device may be derived from a set of operational characteristics common to a set of devices similar to the device. This set of operational characteristics may further be adjusted by operational characteristics related to the device itself. This may allow for more adaptive control signals to be generated for control of portions of the device.

摘要： The present disclosure generally relates to systems and techniques for calibrating displays to improve the white point uniformity between similar type devices. In one embodiment, a backlight includes multiple strings of LEDs, where each string is driven by a separate driver, or driver channel. Each string may be separately tested at a base current to determine its emitted chromaticity, and values indicative of the emitted chromaticities may be stored within the backlight as calibration values. The calibration values may then be used to determine the driving strength for each string that allows the display to produce the target white point when the light from the strings is mixed. Further, in certain embodiments, adjustments also may be made to the LCD panel based on the emitted chromaticities at the base current.

摘要： A system and method for characterizing the power and luminance values for a display. This may include testing a device to determine a luminance value for a display of a given device at a given current and determining whether the first current is to be adjusted during future uses based on a comparison of the luminance with at least one threshold value. This may also include storing an adjusted current value if it is determined that the first current is to be adjusted.
