This document discusses, among other things, an apparatus comprising a pump configured to deliver insulin, a processor, and a user interface including a bistable display. A display element of the bistable display is placed in one of two stable orientations upon application of a biasing voltage and stays in the stable orientation when the biasing voltage is removed. The processor includes a display module configured to display a non-blank reversion display screen on the bistable display when no input is received at the user interface after a specified time duration, and to recurrently change the reversion display screen until input is received at the user interface.

An electronic device includes sensors, a display, and a processor electrically connected to the sensors and the display, in which the electronic device is in a first running mode for permanently providing compass information or a second running mode for providing the compass information, in response to a request from a user. When set to be in the first running mode, the processor a performance mode of a digital compass to be a first performance mode, determines first performance mode-based compass information using the sensors, and displays the determined first performance mode-based compass information on the display. When set to be in the second running mode, the processor sets the performance mode of the digital compass to be a second performance mode, determines second performance mode-based compass information using the sensors at the request from the user, and displays the determined second performance mode-based compass information on the display.

The present invention provides a data processing device connected with an intermission driving. The data processing device achieves a satisfactory power saving while ensuring a high level of display quality of the display device. Upon detection of non-data update in a frame buffer, the host calculates a next refreshing timing based on driving information obtained from a liquid crystal display device (LCD), sets a timer for a timeout after a length of time representing the calculated result, and then the host and the LCD shift to Intermission State 1. Thereafter, when the timer times out to bring the host back to Normal State and a data update at the frame buffer is detected, data for refreshing an display image in the LCD is transferred from the host to the LCD. If the amount of time representing the calculated result is longer than a predetermined baseline, a shift is made to Intermission State 2 which provides greater power saving than Intermission State 1.

According to an example, a system for electronic display illumination comprises a display, a sensor communicatively coupled to the display to detect a user and a user eye gaze, and a processing resource communicatively coupled to the sensor. In some examples, the processing resource may determine an active screen area and an inactive screen area of the display based on the user eye gaze; instruct a display controller to adjust a display value of the inactive screen area; and transmit active screen area data to a secondary display.

A display device is provided, the display device includes a first display portion, a second display portion not in a same plane with the first display portion, and a side display portion connected between the first display portion and the second display portion, a brightness of the second display portion is less than a brightness of the first display portion and a brightness of the side display portion.

Disclosed are an image display device and a method of controlling an image display device. The image display device includes a motion detection unit for detecting a motion of a user and provides a welcome feedback to the user in the form of a visual signal, an audio signal, or both according to whether the motion of the user is detected or not, thereby drawing attention of the user or switching a display state to reduce power consumption of the image display device. The image display device determines a motion exception event that is not regarded a user motion on the basis of an overall change or a local change in pixel value between image frames, thereby preventing the display panel from being activated by a non-human-related factor such as a sudden change in illuminance or a movement of a periodically operating object.

A control method of a power supply path includes detecting a plug-in state of a first connector through a configuration channel pin of the first connector; acquiring a plurality of rated voltages of a first power adaptor externally connected to the first connector and a rated current corresponding to each of the rated voltages; detecting a plug-in state of a second connector through a direct-current (DC) input pin of the second connector; acquiring a power quota of a second power adaptor externally connected to the second connector; selecting, from the plurality of rated voltages, the largest one that is not greater than an operating voltage, as a selected rated voltage; calculating a power quota of the selected rated voltage; and controlling a switching circuit to couple a power circuit to a power pin of one of the first and second connectors according to the two power quotas.

The first time a display device is turned on, is turned on after it has been factory reset, or is factory reset, the display device displays a message indicating that in a default and current power mode of the display device, a hardware component of the display device different than display hardware is powered off when the display device enters a low-power state. A user is permitted to have the hardware component remain powered on when the display device enters the low-power state.

A device including a display screen including display pixels arranged in rows and in columns, including a first row and a first column. The device further includes a display screen control circuit configured to, in a first mode, start the display of a first image on the first row and on the first column and, in a second mode, start the display of a second image on one of the rows different from the first row and/or on one of the columns different from the first column.
