Electronic device and power supply method for electronic device

An example aspect of a backlight system of the present invention includes: a plurality of light emitting elements that operate as a light source of a backlight using bus-supplied electric power in which a voltage is changed to one of a plurality of predetermined values as a power source; a plurality of serial connection switches that connect the plurality of light emitting elements in series and disconnect connections among the plurality of light emitting elements; a plurality of parallel connection switches that connect the plurality of light emitting elements in parallel relative to the power source and disconnect the connections among the plurality of light emitting elements; and a control unit that turns on or turns off the plurality of serial connection switches and the plurality of parallel connection switches in accordance with the value of the voltage corresponding to the bus-supplied electric power.

Backlight system, display apparatus, and control method for backlight system

A display device includes a processing unit that determines whether a plurality of videos can be displayed side by side without overlapping each other in a display unit without changing resolutions of the plurality of videos. When the processing unit determines that the plurality of videos can be displayed, it causes the display unit to display the plurality of videos side by side without overlapping each other without changing the resolutions of the plurality of videos. When the processing unit determines that the plurality of videos cannot be displayed, it changes a resolution of at least one of the plurality of videos based on a resolution of the display unit, the resolutions of the plurality of videos, and a priority order, and causes the display unit to display the plurality of videos including the video for which the resolution has been changed side by side without overlapping each other.
