A main body of this embodiment is a splicing screen. Referring to
It can be seen that, in this embodiment, the splicing screen comprises:
The splicing screen provided in this embodiment is provided with the first unit panel 1 and the second unit panel 2 that are spliced together. The first light-emitting device layer 11 defining a display area AA thereof in the first unit panel 1 overlaps a non-display area NA of the second unit panel 2 for displaying, so as to visually eliminate or weaken visual influence of the non-display area NA on the splicing screen, lift restriction of the non-display area NA on spacing between adjacent pixel units of different unit panels in the splicing screen, and improve visual senses of the splicing screen, which is conducive to realizing a seamless splicing screen with a spacing of less than 0.7 μm between pixel units.
Referring to
It should be noted herein that the above-mentioned unit panel refers to a unit screen that forms a portion of a splicing screen and can be independently displayed. In addition, as shown in
In addition, it should be noted that, for the first unit panel 1 and the second unit panel 2 described above, an implementer may dispose the first unit panel 1 and the second unit panel 2 to have the same structure as shown in this embodiment. An implementer may also dispose the first unit panel 1 and the second unit panel 2 to have different structures. For example, in another embodiment, the first unit panel 1 is specifically a mirco LED display panel, and the second unit panel 2 is a mini LED display panel.
In addition, the first light-emitting device layer 11 mainly refers to a film layer member for performing light-emitting displaying in the first unit panel 1. The first light-emitting device layer 11 comprises a pixel unit, which defines a range of the display area AA of the first unit panel 1. The first light-emitting device layer 11 may be a mirco LED light-emitting device layer or a mini LED light-emitting device layer. In addition, as described above, the first light-emitting device layer 11 overlaps the non-display area NA of the second unit panel 2, that is, the first light-emitting device layer 11 partially covers and shields the non-display area NA of the second unit panel 2 in a positive direction, thereby emitting light and displaying. It should be noted that the positive direction refers to a direction perpendicular to display surfaces of the splicing screen.

Further referring to
In order to reduce influence of a binding structure on overlapping effects of the extension portion 11a, the extension portion 11a can be stably overlapped on the non-display area NA of the second unit panel 2. In this embodiment, the extension portion 11a laps over one side of the chip on film 12 facing away from the second unit panel 2.
Referring to
Accordingly, in this embodiment, the extension portion 11a is concavely formed with a holding opening 12 for holding the chip on film 21. By disposing the holding opening 12, influence of thickness of the chip on film 21 on lapping effects of the extension 11a can be reduced, and surfaces of the display area of the first unit panel 1 and the second unit panel 2 can be kept flush more easily. Ideally, an extension depth of the holding opening 12 in the positive direction is configured such that display surfaces of the first unit panel 1 and the second unit panel 2 are flush with each other. Of course, an implementer may also dispose other depths of the holding opening 12 to weaken influence of thickness of the chip on film 21 on lapping effects of the extension 11a. The holding opening 12 is not limited to realize the fact that display surfaces of the first unit panel 1 and the second unit panel 2 must be flush with each other.
Further referring to
Specific structures of the first unit panel 1 and the second unit panel 2 will be further disclosed below. As described above, the first light-emitting device layer 11 may be a structural layer including a micro LED light-emitting device, or may be a structural layer including a mini LED light-emitting device. However, if a structure provided in a conventional manner is adopted, the first array substrate 13 may be partially cut off when forming the extension portion 11a, so that the extension portion 11a can extend to an outer side of one side edge of the first array substrate, which will increase manufacturing difficulty of the first unit panel 1.
Accordingly, referring to
It should be noted herein that the first bead plate 14 may be shown in
Regarding driving mode of the first bead plate 14, please refer to
Certainly, the foregoing description should not be understood as a limitation on structure of the first bead plate 14. An implementer may further deform structure of the first bead plate 14, for example, so that each first pixel unit 15 comprises only a blue light-emitting chip B and a green light-emitting chip G, and the first pixel unit 15 emits a white light by disposing a red fluorescent layer on the first bead plate 14 and encapsulating the blue light-emitting chip B and the green light-emitting chip G. It should be noted that, in this embodiment, the first light-emitting chip is specifically a micro led light-emitting chip, and the first pixel unit may be used as a backlight of the splicing screen, or may be directly displayed by self-emitting of the chip.
As for set mode of the pin portions 16 on the extension bead plates 14a, as shown in
For the inner bead plates 14b, an implementer may select set mode of the pin portions 16 according to an actual situation, which is not particularly limited in the present application. An ideal set mode is shown in
In more detail, please refer to
In detail, in the embodiment, the common pin 16a is specifically used to connect to cathodes of each first light emitting chip, and the independent pins 16b are used to connect to anodes of the corresponding first light-emitting chips. An independent pin 16b comprises a red chip pin r used to electrically connect to anode of the red light-emitting chip R, a green chip pin g used to electrically connect to anode of the green light-emitting chip G, and a blue chip pin b used to electrically connect to anode of the blue light-emitting chip b.
It can be understood that an implementer can also connect the common pin 16a to anode of each first light-emitting chip, and connect the independent pin 16b to cathode of a corresponding first light-emitting chip, which can also simplify structure of the pin portions 16.
Furthermore, for the first bead plate 14, only one first pixel unit 15 may be included, or a plurality of first pixel units 15 may be collectively packaged as shown in
More specifically, referring to
A main body of embodiment 2 is a splicing screen. Referring to
A main body of embodiment 3 is a splicing screen comprising a splicing screen and a main body. The display device may be any display device such as an iPad, a mobile phone, a computer display, or a VR device. The above-described splicing screen may be the splicing screen as described in either Embodiment 1 or Embodiment 2, and the splicing screen is disposed on the main body. It should be noted here that the main body may be the whole or a part of the display device other than the display screen.
