Abstract: A display apparatus includes gate lines extending in a first direction, data lines extending in a second direction crossing the first direction, first color pixels, and second color pixels. A first color pixel arranged in an f-th column between an f-th data line and an (f+1)th data line is connected to one of the f-th data line and the (f+1)th data line. A first color pixel arranged in a g-th column between a g-th data line and a (g+1)th data line is connected to one of a (g−1)th data line and a (g+2)th data line. First color pixels in a first color pixel diagonal group receive data voltages having a same polarity.Second color pixels in a second color pixel diagonal group receive data voltages having a same polarity.

Abstract: A display device includes an interface, a power supply, a switch arrangement, and a display. The interface is driven by driving power and receives image data from an external source. The power supply generates first and second power based on a first input power in a first mode and delivers the driving power to the interface in the first mode. The switch arrangement forms a first delivery path to deliver the first power from the power supply to the interface in the first mode The display receives the second power from the power supply when driven in the first mode and receives the image data from the interface. The switch arrangement forms a second delivery path to deliver second input power to the power supply in a second mode when the interface receives the second input power from the external source in the second mode.

Abstract: A display device includes a memory, a signal controller, and a voltage generator. A plurality of data is stored in the memory. The signal controller detects a frame rate of an externally applied image data signal, selects data corresponding to the detected frame rate among the plurality of data, and outputs a control signal corresponding to the selected data. The voltage generator includes a DC-DC converter for determining an output voltage in correspondence to the control signal and a feedback circuit for determining a current flowing inside and a frequency of an outputted signal in correspondence to the control signal.
