  • Publication number: 20240105098
    Abstract: A display device including a display panel is disclosed. The display panel includes a substrate, multiple scan lines, multiple data lines, multiple pixel structures, a first gate driving circuit, and a second gate driving circuit. The pixel structures are electrically connected to the scan lines and the data lines. Multiple first output stage circuits of the first gate driving circuit disposed in a peripheral area are electrically connected to the scan lines. Multiple second output stage circuits of the second gate driving circuit disposed in the peripheral area are electrically connected to the scan lines. A channel width of a first output transistor of the first output stage circuit is greater than a channel width of a second output transistor of the second output stage circuit.

  • Publication number: 20230411407
    Abstract: A display panel including a substrate, scan lines, data lines, and pixel structures is provided. The pixel structures are electrically connected to the data lines and the scan lines. Each pixel structure includes an active device, a pixel electrode, a capacitor electrode, a common electrode, an overcoat layer, a first passivation layer and a second passivation layer. The active device is electrically connected to the pixel electrode. The capacitor electrode is electrically connected to the pixel electrode. The common electrode is located between the capacitor electrode and the pixel electrode. The common electrode, the capacitor electrode and the pixel electrode overlap with each other. The overcoat layer is disposed between the common electrode and the first passivation layer. The second passivation layer is disposed between the common electrode and the pixel electrode.
