Abstract: An electronic device includes: a printed circuit board on which an electronic component is mounted; a case comprising a board mounting portion, on which the printed circuit board is mounted, the board mounting portion comprising an interference wall; and a mounting member fixed to the printed circuit board and configured to fix the printed circuit board to the board mounting portion, the mounting member including an interference portion configured to interfere with the interference wall and a scratch protrusion protruding from the interference portion and configured to scratch an outer surface of the interference wall in a state in which to the interference portion interferes with the interference wall.

Abstract: Provided is a display apparatus. The display apparatus includes: a display panel; a chassis supporting the display panel; a printed circuit board on which an electronic component is mounted; and a supporter inserted in the printed circuit board, wherein the printed circuit board includes a first surface facing the chassis, a second surface facing a direction opposite to the first surface, and a through hole penetrating the first surface and the second surface. The supporter includes: a head fixed on the second surface of the printed circuit board; a first body positioned inside the through hole, and extending from the head toward the chassis; and a second body extending from the first body, and protruding from the through hole toward the chassis.

Abstract: An electronic apparatus includes a power factor correction (PFC) circuit including an inductor and a switch serially connected to the inductor, and a control circuit. The control circuit, based on an amount of current flowing in the PFC circuit being less than or equal to a threshold current, operates the PFC circuit in a standby mode, and based on an output voltage of the PFC circuit being less than a threshold output voltage corresponding to the standby mode, adjusts the output voltage to correspond to a reference voltage by applying a signal for on-off control of the switch in the PFC circuit to the switch. The control circuit identifies an on-off frequency of the switch based on a reference current level for limiting a peak current of the inductor included in the PFC circuit in the standby mode, and applies the signal to the switch based on the on-off frequency.

Abstract: An electronic apparatus is provided.

Abstract: A display apparatus includes a power supply device. The power supply device includes a power supply part and an integrated circuit chip. The power supply part outputs a first power to drive a backlight and a second power to drive a main circuit. The integrated circuit chip increases, based on a control signal to adjust a brightness of the backlight being received, a current value of the second power, and reduces, based on the control signal not being received for a first threshold time, the current value of the second power.
