Abstract: An adjusting device for adjusting a driving voltage of a light-emitting element is provided. The adjusting device includes a driving circuit and a control circuit. The control circuit is configured to generate a voltage difference. A control signal indicates that brightness of a display is adjusted from first brightness of the display to second brightness of the display, and the driving circuit adjusts the driving voltage according to the voltage difference. The control circuit queries a look-up table to obtain a first voltage corresponding to the first brightness of the display and a second voltage corresponding to the second brightness of the display. The voltage difference is obtained from the difference between the first voltage and the second voltage. The first voltage and second voltage respectively indicate the minimum cross-voltages required by the light-emitting element under the first brightness of the display and the second brightness of the display.

Abstract: An electronic device bearing seat includes a casing, a hook, a first resilient element, an ejector, a second resilient element, a pivot, a connecting rod and an ejecting button. The casing has a first opening and a second opening. The hook is movably provided in the first opening and includes a first withstanding post and a recess. The first resilient element is disposed between the casing and the hook. The ejector is movably provided in the second opening and is detachably fastened in the recess. The ejector includes a second withstanding post. The second resilient element is disposed between the casing and the ejector. The shaft is disposed in the casing. The connecting rod is rotatably disposed at and passed by the pivot and pushes against the first and second withstanding post. The ejecting button is movably disposed on the casing and abuts against the connecting rod.
