Abstract

Embodiments of the present invention provide a display panel, a manufacturing method thereof, and a display device, which relate to the technical field of display and improve display uniformity. The display panel includes an array substrate, the display area includes a plurality of sub-pixel areas, and the sub-pixel area includes a display sub-pixel area and a spare sub-pixel area; in the first direction and the second direction, the display sub-pixel area and the spare sub-pixel area are alternately arranged; The display sub-pixel region is provided with a display anode and a display cathode, and at least part of the spare sub-pixel region is provided with a spare anode and a spare cathode; at least part of the display anode of the display sub-pixel region is connected to the spare anodes of at least two spare sub-pixel regions, and / Or, at least part of the spare sub-pixel area is provided with at least two spare anodes, and the at least two spare anodes are respectively electrically connected to the display anodes of the at least two display sub-pixels in one-to-one correspondence; it also includes light-emitting diodes, including a plurality of display light-emitting diodes , the positive pin is bound to the display anode, and the negative pin is bound to the display cathode.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. 【Background technique】 [0002] For light-emitting diode display panels, such as micro LED display panels, in the manufacturing process, the light-emitting diodes formed on the growth substrate need to be transferred to the array substrate by mass transfer. If the number is too large, it will inevitably appear dead pixels due to the impact of the transplant yield. [0003] For this reason, in the prior art, such as figure 1 shown, figure 1 It is a schematic diagram of the arrangement of sub-pixel regions in the prior art. On the array substrate, a row of display sub-pixel regions 1 ′ for binding display light-emitting diodes and a row of spare sub-pixel regions 2 for binding spare light-emitting diodes ' are alternately arranged in the column direction, and each spare sub-pixel area 2' is pr...

Problems solved by technology

[0004] However, in practical applications, only a small number of spare sub-pixel regions 2' are bound with spare light-emitting diodes, and there are no light-emitting diodes in other spare sub-pixels 2'. Therefore, if the above arrangement is adopted, when the display panel emits light, the spare A dark line will appear in the area where the sub-pixel 2' is located, which will affect the display effect
