Abstract: A display panel and a display device. Because the pixel distribution density in a second display subarea (A12) is lower than that in a first display subarea (A11), the quantities of sub-pixels (pix) connected to scanning lines are not completely the same; a sub-pixel row having the greatest quantity of sub-pixels (pix) in the display panel is taken as a reference sub-pixel row, the quantity of the sub-pixels (pix) of the reference sub-pixel row is taken as a reference value, a sub-pixel row having the quantity of sub-pixels (pix) smaller than the reference value is taken as a compensation sub-pixel row, and a scanning line connected to the compensation sub-pixel row is taken as a first scanning line; the display panel is provided with load compensation units corresponding to at least part of the first scanning lines, and the load compensation units are located in the second display subarea.

Abstract: A pixel circuit, a display apparatus, and a driving method. The pixel circuit include: a driving circuit, a data writing circuit, a compensation circuit, a light emission control circuit, a first reset circuit, a second reset circuit, and a light-emitting element. The data writing circuit is for writing a data signal into the first terminal of the driving circuit based on a writing control signal; the first reset circuit is for applying a first reset voltage to the control terminal of the driving circuit based on a first reset control signal; and the second reset circuit is for applying a second reset voltage to a first electrode of the light-emitting element based on a second reset control signal. The writing control signal and the second reset control signal are synchronized in each write frame, and the writing control signal remains at an invalid level in each skip frame.

Abstract: The present disclosure provides a display motherboard, a method for fabricating the same, and a method for aligning the same. The display motherboard includes an array substrate on which an alignment mark and a color film layer are provided. A portion of a black matrix of the color film layer in an alignment mark area includes a first light-shielding portion and a second light-shielding portion. The first light-shielding portion covers the alignment mark, and the second light-shielding portion covers an area outside the alignment mark, where upper surfaces of the first light-shielding portion and the second light-shielding portion are not in the same plane. When the display motherboard is aligned in the subsequent processes, since the black matrix forms the same pattern as the alignment mark due to a height step, when the exposure machine exposures, the pattern can be directly captured for alignment.
