    摘要： A method of driving a light emitting diode (LED) backlight unit, which includes a plurality of LED elements that are connected to a plurality of gate lines and a plurality of source lines, includes generating a plurality of gate signals applied to the plurality of gate lines. While the plurality of gate signals are generated, a non-overlap interval between activation intervals of two adjacent gate signals is generated. All of the plurality of gate signals are deactivated during the non-overlap interval. A plurality of source signals applied to the plurality of source lines are generated. While the plurality of source signals are generated, a high-impedance (Hi-Z) interval included in the non-overlap interval is generated. At least some of the plurality of source signals have a high-impedance state during the high-impedance interval.

    摘要： A method for displaying and transmitting images and an electronic device thereof are provided. The electronic device includes a first display, a second display separated from the first display, a transceiver, at least one processor electrically connected to the first display, the second display, and the transceiver, and a memory electrically connected to the at least one processor. The at least one processor is configured to display a first screen image on the first display, provide a second screen image on the second display at least partially simultaneously with the displaying of the first screen image on the first display, provide data associated with one of the screen images to the transceiver, and control the transceiver to transmit the data to an external device such that a screen image at least partially identical to one of the screen images is output on a display of the external device.
