Abstract
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.
