Abstract: A power supply device comprises: a switching converter using input power of AC or DC supplied through an input power unit, having a switch, and generating output power by using an on-off action of the switch; a driving controller generating a first control signal for controlling the on-off action of the switch of the switching converter; a level converter receiving the first control signal from the driving controller and outputting a second control signal to the switch of the switching converter, and a voltage generator supplying a power source to at least one among the switching converter, the driving controller, and the level converter.

Abstract: A power supply device according to one aspect of the present invention comprises: a switch including a first terminal and a second terminal receiving a control signal, the switch operating to be turned on or off by comparing the magnitude between a threshold voltage and a voltage between the first terminal and the second terminal; and a protection element connected to the first terminal to change the magnitude of a source voltage of the first terminal, wherein the magnitude of the source voltage of the first terminal may be adjusted to be higher than when the protection element is not present.

Abstract: A source driver and a display device having the same are provided. The source driver shares several outputs by using a time division method and has an analog voltage stored in a buffer supplied to each data line multiple times during a horizontal scanning interval. Accordingly, by supplying an analog voltage to a data line a first time in a first activation interval and supplying an analog voltage to a data line a second time in a second activation interval, a target voltage of each pixel may be achieved quickly and accurately.

Abstract: A light emitting pixel includes a first organic light emitting diode (OLED) and a capacitor supplying to the first OLED current generated by an electric charge corresponding to a difference between a first voltage supplied to a first electrode of the capacitor and a second voltage supplied to a second electrode of the capacitor.
