A device comprising a display and a display controller. The display comprises a first display portion and a second display portion. The display controller is configured to assess a temperature condition of a surface of the first display portion; and responsive to the temperature condition, to initiate a switching of display content from one of the display portions to the other display portion.

Dynamically switching display in use based on temperature

Thermal management devices and systems, and corresponding methods of cooling an electronic device are described herein. A method for cooling an electronic device that includes a housing and a vent in the housing includes monitoring, by a sensor, an operating condition of the electronic device. The vent is opened or closed based on the monitored condition of the electronic device.

Self-adaptive vents

Cooling of an electronic device that includes a first portion and a second portion is provided. The first portion and the second portion are rotatable relative to each other. A first sensor measures a first temperature at a first location within or on the electronic device continuously or intermittently. A second sensor measures a second temperature at a second location within or on the electronic device continuously or intermittently. A processor identifies a first state of the electronic device or a second state of the electronic device. The processor controls operation of the electronic device based on the first measured temperature and the second measured temperature when the electronic device is in the identified first state and controls the operation of the electronic device based on the first measured temperatures but not based on the second measured temperatures when the electronic device is in the identified second state.

Device configuration-based thermal management control

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.

Dynamic voltage display driver

This document relates to providing a thermal management system for a device. One example determines temperature readings associated with one or more components of the device, and comparing the temperature readings to optimal operating temperatures. This example can selectively couple or decouple heat-dissipating elements based at least on the temperature readings associated with the one or more components of the device in order to reach the optimal operating temperatures.

Adaptive heat dissipation frame

Cooling of an electronic device is described herein. A sensor located at a first position determines a temperature at the first position. A processor identifies a fan speed of a fan positioned within the electronic device. The processor identifies a correlation between at least the determined temperature at the first position and the identified fan speed of the fan, and a temperature at a second position. The processor calculates an expected temperature at the second position using the identified correlation based on the determined temperature at the first position and the identified fan speed of the fan. The processor compares the calculated expected temperature at the second position to a predetermined temperature for the second position. The processor controls, based on the comparison, at least one component of the electronic device when the calculated expected temperature at the second position is greater than the predetermined temperature for the second position.

Thermal management hinge

Techniques for selectively rotatable feet for an apparatus are described. According to various implementations, an apparatus includes feet on its base that cushion the apparatus on an adjacent surface, such as a desk, a table, and a floor. The feet are rounded (e.g., spherical) and can rotate relative to the base to enable the apparatus to be moved on an adjacent surface. To prevent unwanted movement during a typical usage, the apparatus includes brakes that engage with the feet to prevent rotation. The brakes, however, can be selectively disengaged from different feet to enable different types of movement of the apparatus, such as rotational and translational movement.
