The present disclosure provides a display device including a display panel and a scan driver. The display panel displays an image. The scan driver includes a scan signal generation circuit disposed on one side of the display panel, and an emission signal generation circuit disposed on the other side of the display panel. The emission signal generation circuit outputs an emission signal having at least two Logic High sections in response to an external clock signal and a first scan signal output from the scan signal generation circuit.

Scan driver, display device, and method of driving display device

The present disclosure provides a display device including a display panel and a scan driver. The display panel displays an image. The scan driver includes a scan signal generation circuit disposed on one side of the display panel, and an emission signal generation circuit disposed on the other side of the display panel. The emission signal generation circuit outputs an emission signal having at least two Logic High sections in response to an external clock signal and first and second scan signals output from the scan signal generation circuit.

An apparatus comprising a circuit configured to control anode voltages of one or more adjacent pixel rows, which are adjacent to an Nth pixel row, to achieve minimal voltage differences between said Nth pixel row and said adjacent pixel rows to suppress luminance drops in an OLED display by minimizing leakage currents being introduced from adjacent pixel rows.

Organic light emitting diode display device including pixel driving circuit

A display device is disclosed to include a display panel including a plurality of data lines, a plurality of gate lines, and a plurality of pixels coupled to the data lines and gate lines. The data lines include first and second data lines, and the pixels include first and second color pixels. The display device also includes a data driving circuit to generate data voltages through a plurality of output channels, a gate driving circuit coupled to the gate lines, and a timing controller to generate control signals to the data driving circuit and the gate driving circuit. The display device further includes a demultiplexer switching circuit with first demux switches to supply, when turned on, the data voltages from the output channels to the first data lines, and second demux switches to supply, when turned on, the data voltages from the output channels to the second data lines.
