Abstract: An electronic device, a foldable-slider device, and a method for displaying information are disclosed. The electronic device may include a housing assembly (10) and a display screen (20). The housing assembly (10) may include a first housing portion (11), a second housing portion (12), and a foldable portion (13). The display screen (20) may have a shortcut display area (211). In a condition of the foldable portion (13) being in a folded state, the second housing portion (12) can be enabled to slide between a first folded position where the shortcut display area (211) is covered by the second housing portion (12) and a second folded position where the shortcut display area (211) is exposed from the second housing portion (12).

Abstract: The present invention discloses a method for reducing a self-mixing interference effect of a laser system, comprising the following step: connecting a direct current (DC) bias circuit and a modulated signal generator to electrodes of a laser, respectively. The DC bias circuit is configured to drive the laser and provide carriers for pumping to the laser; a resonant cavity is provided in the laser, and is configured to convert the carriers for pumping into photons which are subjected to stimulated radiation to form stable laser output; the DC bias circuit and the modulated signal generator are injected into the laser; the modulated signal generator outputs a modulated signal; and the modulated signal matches a parasitic parameter of the laser so as to change the distribution state of the photons in the resonant cavity of the laser.
