Abstract: A flexible display panel, a method for fabricating the same, and a display device are provided. A protruding structure located is formed in a via-hole area on a flexible base substrate so that both the protruding structure, and the portions of an organic light-emitting functional film and a top electrode layer covering the protruding structure can be removed. Thereafter an encapsulation thin film covering the patterns of the organic light-emitting functional film and the top electrode layer is formed. After the encapsulation thin film is formed, the step of removing the pattern of the encapsulation thin film in the via-hole area can be further performed to expose the flexible base substrate in the via-hole area, and after the flexible base substrate in the via-hole area is removed, a via-hole can be formed in the flexible base substrate.

Abstract: A display panel, a manufacturing method thereof and a display device are provided. The display panel includes a plurality of functional layers arranged on a base substrate. A portion of at least one of the functional layers is removed to form a gap portion. The display panel further includes a light-transmissible structure including the gap portion and configured to allow a light beam to pass therethrough to an optical sensing element arranged at a position corresponding to the light-transmissible structure. An orthogonal projection of the gap portion onto the base substrate overlaps an orthogonal projection of the optical sensing element onto the base substrate.

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.
