摘要: A display driving system includes a timing controller, a level shifter and a power supply circuit. The timing controller is configured to send first clock signals having a first level, a second level and a third level to the level shifter. The second level is less than the first level and greater than the third level. The power supply circuit is configured to output a first, second and third voltage signals to the level shifter. The second voltage signal has a second voltage less than a first voltage of the first voltage signal and greater than a third voltage of the third voltage signal. The level shifter is configured to transmit the first voltage in response to the first level, the second voltage to in response to the second level and the third voltage in response to the third level, to a gate driver circuit.

摘要: An array substrate, a display panel, a display device, an operating method, and a manufacturing method are disclosed. The array substrate includes a wiring structure formed on a base substrate, and the wiring structure includes a common electrode line for connecting a common electrode, and a plurality of signal lines. The plurality of signal lines include at least one pair of signal lines, and the pair of signal lines include a first signal line and a second signal line. The first signal line is disposed on a first side of the common electrode line and is configured to transmit a driving signal for a gate driving circuit. The second signal line is disposed on a second side of the common electrode line and is configured to transmit an inverted signal of the driving signal.
