A display device, includes a substrate; first to fourth subpixels sequentially arranged on the substrate; a first power line on a left side of the first subpixel and shared by the first and second subpixels; a sensing line between the second subpixel and the third subpixel and shared by the first to fourth subpixels; a second power line on a right side of the fourth subpixel and shared by the third and fourth subpixels; and a first data line on the left side of the first subpixel, a second data line on a right side of the second subpixel, a third data line on a left side of the third subpixel, and a fourth data line on the right side of the fourth subpixel. The first and second power lines and the sensing line are disposed on a layer different from the first to fourth data lines.

Display device

A display device and a method of driving the same are disclosed. The display device includes a display panel configured to display an image, a plurality of data lines arranged in a first diagonal direction of the display panel, a plurality of scan lines arranged in a second diagonal direction intersecting the first diagonal direction of the display panel, a plurality of data drivers connected to the plurality of data lines, and a plurality of scan drivers connected to the plurality of scan lines.

Display device and method of driving the same

A display device includes a plurality of pixels, and a pixel disposed in a n-th pixel line has a light emitting diode, a driving TFT to control a current flowing the light emitting diode, a capacitor connecting a source of the driving TFT and a gate of the driving TFT, a first TFT controlled by a first gate signal which is transferred through a first gate line to connect the gate of the driving TFT to one of data lines, a second TFT controlled by a second gate signal which is transferred through a second gate line to connect the gate of the driving TFT to an initialization voltage, and a third TFT controlled by the second gate signal transferred to a pixel disposed in a (n&#x2212;1)-th pixel line to connect the source of the driving TFT to a reference voltage, n being a natural number.

Provided is a single input level shifter. The single input level shifter includes: an input unit applying a power voltage to a first node in response to an input signal and applying the input signal to a second node in response to a reference signal; a bootstrapping unit applying the power voltage to the second node according to a voltage level of the first node; and an output unit applying the input signal to an output terminal in response to the reference signal and applying the power voltage to the output terminal according to the voltage level of the first node, wherein the bootstrapping unit includes a capacitor between the first and second nodes, and when the input signal is shifted from a first voltage level to a second voltage level, the bootstrapping unit raises the voltage level of the first node to a level higher than the power voltage.
