[0051] The embodiment of the present application provides a display panel 100. The display panel 100 includes: at least one display component 10, a driving substrate 20, and a conductive member 30. The display component 10 includes a first base 11, and at least A first terminal 12, and a light-emitting layer 19, the light-emitting layer 19 is electrically connected to the first terminal 12; the driving substrate 20 includes a driving chip 60, a second base 21, and a plurality of second terminals 22 arran...

Embodiment 2

[0092] This embodiment is the same or similar to the display panel in the above embodiments, except that the sub-through hole 51 also extends to the inside of the first terminal 12 .

[0093] see Figure 4 , Figure 4 It is a second schematic diagram of the display panel 100 provided by the embodiment of the present application.

[0094] The embodiment of the present application provides a display panel 100 . Compared with the first embodiment, the sub-through hole 51 also extends to the inside of the first terminal 12 .

[0095] Specifically, when a plurality of sub-vias 51 are formed by laser, the sub-vias 51 also extend to the inside of the first terminal 12 at the same time.

[0096] Specifically, when the first sub-vias 31 are formed in the sub-vias 51 , the first sub-vias 31 also fill the part of the sub-vias 51 extending to the inside of the first terminal 12 .

[0097] In the embodiment of the present application, the arrangement of the through hole group 50 also ha...

Embodiment 3

[0101] This embodiment is the same as or similar to the display panel in the above embodiments, except that the sub-through hole 51 also passes through the first terminal 12 .

[0102] see Figure 5 , Figure 5 It is a third schematic diagram of the display panel 100 provided by the embodiment of the present application.

[0103] In the embodiment of the present application, compared with the first and second embodiments, the sub-through hole 51 also penetrates the first terminal 12 .

[0104] Specifically, in some implementation situations, the size of the first terminal 12 is small and the thickness is relatively thin, and when the sub-through hole 51 does not penetrate the first terminal 12, the contact area between the first terminal 12 and the side surface of the conducting member 30 is not large enough. .

[0105] Specifically, when the sub-through hole 51 also passes through the first terminal 12 , the contact area of ​​the first terminal 12 with the side surface of ...

Abstract

In the embodiment of the invention, the display panel and the display terminal are provided, the display panel comprises at least one display assembly, a driving substrate and a conduction piece, the display assembly comprises at least one through hole group, the through hole group is arranged between the corresponding first terminal and the corresponding second terminal, each through hole group comprises a groove and a plurality of sub through holes, and the sub through holes are arranged in the groove. The groove is located in the surface of the side, facing the driving substrate, of the first substrate, the sub-through hole penetrates through the surface of the side, away from the groove, of the first substrate, the sub-through hole is connected between the first terminal and the groove, and the groove and the sub-through hole are at least filled with the conduction piece. According to the embodiment of the invention, the process window of the laser drilling process can be improved by arranging the plurality of sub through holes, the yield of the drilling process is improved, and meanwhile, the contact area of the conduction piece and the first terminal is increased by arranging the groove, so that the contact property of the conduction piece and the first terminal is improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a display terminal. Background technique [0002] Display panels have been widely used in people's lives. In the production and manufacture of large-size display panels, such as the production and manufacture of large-size organic light-emitting display panels (OLED), there are still problems such as relatively difficult production and low yield. Therefore, a method of splicing small-size display components into a large-size display panel has been developed. In the spliced ​​large-size display panel, multiple small-size display components are spliced ​​and arranged on a large-size drive substrate. Each display component includes The array functional layer and the light-emitting functional layer, the array functional layer is equivalent to each film layer on the array substrate, the array functional layer includes structures such as thin film transistors (TFTs), d...
