The present embodiment relates to a touch power management circuit and a touch driving system including the same, and more particularly, to a touch power management circuit that prevents unnecessary power consumption during a pen touch driving period in order to reduce power consumption of a display device, and a touch driving system including the same.

A method of determining a model for pixel power consumption for each pixel in a display of a device displaying each color in a color space is disclosed which includes establishing a color space for the display, decomposing the color space into a plurality of subgrids, measuring the pixel power associated with a selected set of colors in each subgrid of the plurality of subgrids, establishing a pixel power model for each subgrid of the plurality of subgrids by applying a function to the power values at the selected set of colors in that subgrid, and deriving a piecewise pixel power model for the entire color space which includes pixel power models for the plurality of subgrids.

An electronic device includes a first screen and a second screen. A high-power sensor of the electronic device is in a disabled state, and a low-power sensor of the electronic device is in an enabled state. The electronic device includes a foldable device. Based on this, after the electronic device receives a screen-on trigger signal from the low-power sensor or a processor of the electronic device, the electronic device determines a to-be-lit-up first target screen based on the screen-on trigger signal, and then controls the first target screen to be lit up.

A method includes obtaining a request for one of multiple operational modes from an application installed on an extended reality (XR) device or an XR runtime/renderer of the XR device. The method also includes selecting a first mode of the operational modes, based at least partly on a real-time system performance of the XR device. The method also includes publishing the selected first mode to the XR runtime/renderer or the application. The method also includes performing a task related to at least one of image rendering or computer vision calculations for the application, using an algorithm associated with the selected first mode.

In one embodiment, a system includes power management control that controls a duty cycle of a processor to manage power. The duty cycle may be the amount of time that the processor is powered on as a percentage of the total time. By frequently powering up and powering down the processor during a period of time, the power consumption of the processor may be controlled while providing the perception that the processor is continuously available. For example, the processor may be a graphics processing unit (GPU), and the period of time over which the duty cycle is managed may be a frame to be displayed on the display screen viewed by a user of the system.

A display control device includes a first display capable of color display, a first controller performing reset control of the first display, and a second controller having less throughput than the first controller. The first controller executes reset control on the first display in a case of a first operation mode in which the first controller is active. The second controller executes reset control on the first display in a case of a second operation mode in which the first controller is inactive or in a case of detection of the first controller not operating normally.

Systems, methods, and apparatus for presenting information and performing a task using an electronic device. In some aspects, a device shows content items when a gaze or a shaking act plus a gaze are detected. In some aspects, a device performs a task when a name, a code, and the task are detected in voice input. In some aspects, a user communicates with a selected vehicle via a user device.

Aspects of the subject technology relate to power consuming processes of electronic devices. For example, an electronic device may create, initiate, and/or modify a power consuming process of the electronic device, based in part on user power consumption information that indicates a typical amount of power consumed by a user of the electronic device. The electronic device may recommend increases in power consumption for low power consumption users and/or decreases in power consumption for high power consumption users. A power consumption process may include a visual arrangement of graphical elements that each display periodically, occasionally, and/or continuously updated information from the application, when a full user interface of the application is not displayed.
