Abstract:
A display device may include first to third semiconductor light-emitting devices in each of a plurality of pixels, a sensing element, and a circuit block in each of the plurality of pixels. The sensing element may include a fourth semiconductor light-emitting device. The first to third semiconductor light-emitting devices may emit light during the first section by a power source having a forward bias. The fourth semiconductor light-emitting device may be light-received by a power source having a reverse bias.
Abstract:
A display apparatus includes a plurality of first brackets adhered to the rear panel. A first bracket has a recess on a first surface where an adhesive is applied, and a first protrusion extending from a second surface and a second protrusion extending from the first protrusion. A connection bracket has a side wall and a plurality of first tab portions. The tab portion is provided into an opening of the first protrusion. A second bracket is provided adjacent to the plurality of the first brackets and attached to the connection bracket. A frame is mounted to the at least one second bracket. A light source is provided between the frame and the second bracket.
Abstract:
A motor driving apparatus includes: an inverter that includes a plurality of switching elements and that is configured to output AC power to a motor by a switching operation of the plurality of switching elements, a switching unit that includes a relay and that is configured to switch a connection mode of the motor by an operation of the relay, and an inverter controller configured to control the inverter and the switching unit. The inverter controller is configured to, based on the relay being turned off, apply a reverse voltage to the relay.
Abstract:
A method of controlling an air conditioner includes a step of sensing the capacitance of condensed water through a plurality of electrode pads to sense the level of condensed water stored in a condensed water storage part during cooling, a step of comparing the sensed level of the condensed water with a drainage level stored in a memory, and a step of, upon determining that the sensed level of the condensed water is within an error range of the drainage level, operating a drainage pump. A water level detecting device of the air conditioner more accurately senses the level of condensed water based on the capacitance of the condensed water, thereby effectively controlling the drainage pump.
