A method of thermal and power control in a computing device includes, at the computing device, initializing a thermal module of the computing device, receiving data at the thermal module from a first component assigned to an interface of the thermal module, and sending an output to a second component from the thermal module based on the data. Initializing the thermal module includes detecting a presence of a plurality of potential components of the computing device; querying each of the plurality of potential components to determine capabilities of each component; in response to the querying, for each of at least a subset of the plurality of potential components receiving identification information for the component and, based on the received identification information, configuring one or more interfaces of the plurality of predefined interfaces of the thermal module to establish communication with the sub set of components.

Systems and methods for thermal system management

A dynamic peak power management system may prevent brownouts while improving performance and user experience compared to conventional techniques. A current threshold may be set below the maximum current capability (Imax) of a battery. If the current drawn from the battery exceeds the current threshold repeatedly, then system components may be throttled to decrease their peak power usage. If the current drawn from the battery stays below the current threshold for some time, then system components may be unthrottled to improve performance. This dynamic adaptable technique for managing peak power does not unnecessarily sacrifice performance by preemptively throttling system components to avoid the rare worst-case scenario where power spikes of system components perfectly align in time.

OLED display color output may vary substantially as a function of display temperature, which changes over time. Luminance of each of the pixels is defined by the current flowing therethrough, which is a function of the applied voltage and resistivity of the pixels. Temperature affects the resistivity of the pixels and thus the current flowing therethrough if voltage is held constant. The temperature response of red, green, and blue pixels differs, particularly at low applied voltage levels. As a result, the relative luminance of red, green, blue may vary with temperature changes, which may yield an undesirable overall color variance. The presently disclosed systems and methods dynamically adjust driving voltage to maintain color quality within a desired specification, while also reducing (or in some implementations, minimizing) power consumption of the OLED display.
