The present disclosure provides a display motherboard, a display panel, and a method for fabricating a display panel, wherein the display motherboard includes a plurality of rows of display units, and a first side edge of the display panel is provided with a first row of display units and a second side edge of the display panel is provided with a second row of display units; an electrode overlap area of a storage capacitor of the first row of display units is gradually increased from a second side to a first side of the first row of display units; an electrode overlap area of a storage capacitor of the second row of display units is gradually increased from a first side to a second side of the second row of display units. The present disclosure performs gradual compensation for the storage capacitor with respect to uniform luminance at a low gray scale caused by unevenness in a manufacturing procedure and adjusts a size of the storage capacitor according to a variation amount in the manufacturing procedure, to and ensure that current flowing through each light emitting diode in the display panel is substantively the same, thus improving luminance uniformity of the display panel at a low gray scale.

Display motherboard, display panel, and fabricating method of display panel

The disclosure comprises a first to a seventh transistor, a capacitor and a light-emitting diode, the second end of the first transistor, the first end of the fifth transistor and one end of the capacitor being connected at the first node, the first end of the second transistor, the control end of the third transistor and the other end of the capacitor being connected at the second node. The second ends of the second, the third and the forth transistor is connect at the third node, the first end of the forth transistor and the first end of the seventh transistor is connected to the anode of the light-emitting diode. The second end of the sixth transistor is connected to the second node, and the second end of the fifth transistor, the first end of the sixth transistor and the second end of the seventh transistor connect with each other.

Pixel compensating circuit

A display device includes a pixel array, a scan driving unit, a light emitting driving unit and a light emitting switch unit. The scan driving unit is configured to provide a scan signal to the pixel array, the light emitting driving unit is configured to provide a light emitting signal to the pixel array, and the light emitting switch unit is configured to provide a switch signal to the pixel array, wherein the display device performs a progressive displaying when the light emitting driving unit is enabled and performs a simultaneous displaying when the light emitting switch unit is enabled.
