Problems solved by technology

[0006] 1. Disadvantages of using soft OLED display splicing: the splicing of the soft OLED display in the described technology is to place the non-image area on the edge of each OLED display at a certain angle (greater than or equal to 90 degrees) to the OLED display. The back is bent to form a bending part, and then the bending part of each soft OLED display is closely attached to the bending part of each adjacent soft OLED display, so as to realize splicing in the two-dimensional direction
In the above technology, bending the soft OLED display screen is easy to cause damage to the OLED display screen, reducing the mass production rate of the product, and increasing the production cost; in the above technology, the soft OLED display screen is bent backward by 90 degrees or greater than 90 degrees, The technology requires high technology and is complex; in the technology, the bending parts of the soft OLED display are directly attached to each other and spliced ​​together, resulting in a gap of a certain width between adjacent OLEDs, which affects the integrity and continuity of the image. , reduce the image quality;
[0007] 2. Disadvantages of using hard OLED display splicing: The splicing of hard OLED displays in the described technology is to draw wires from the side of the hard OLED display, and connect the side of each hard OLED display to the adjacent hard OLED display. The sides of the screen are attached to each other to achieve splicing
In the above technology, the wires are distributed on the side of the hard OLED, which requires a special process, the process is complicated, and the production cost is high; in the technology, the wires are drawn between adjacent hard OLED screens, resulting in a certain width between adjacent OLED screens. The gap affects the integrity and continuity of the image and reduces the image quality; the squeeze between adjacent screens in the technology causes damage to the wires and reduces the life of the wires

Embodiment 1

[0043] An OLED seamless splicing display, comprising a prefabricated installation board 1 and a plurality of OLED splicing units 2, the OLED splicing unit 2 includes a light-emitting display area 3, an electrode lead-out area 4, connection terminals 5 and a drive circuit 6, the electrodes The lead-out area 4 is set on both sides adjacent to the light-emitting display area 3 to form an "L"-shaped electrode lead-out area; the connecting terminal 5 is set on the "L"-shaped electrode lead-out area, and the "L"-shaped electrode lead-out area is provided with Prefabricated cutouts, the driving circuit 6 is arranged on the back of the OLED splicing unit 2, and the plurality of OLED splicing units 2 are arranged on the prefabricated mounting board 1, and are spliced ​​through the prefabricated cutouts to form an OLED display module, and the OLED display modules are multiplied by M rows. N columns form a combined OLED display.

[0044] In the present invention, the "L"-shaped electrode...

Embodiment 2

[0057] The difference from Embodiment 1 is that only the upper electrode lead-out area of ​​each OLED splicing unit is provided with connection terminals 5, and when the present invention is in use, the lower prefabricated cutout 8 of the first OLED splicing unit 11 is connected to the second The upper prefabricated cutout 7 of two OLED splicing units 12 is spliced, and then the lower prefabricated cutout 8 of the second OLED splicing unit 12 is spliced ​​with the upper prefabricated cutout 7 of the third OLED splicing unit 12, thereby forming three OLEDs. The stitching unit is a stitching group of the substrate.

[0058] According to this method of design, when splicing, a splicing group with four or five OLED splicing units as the substrate can be formed; the splicing area can be increased in the horizontal, vertical or horizontal and vertical directions at the same time, and a super large OLED display can be spliced; And it has the advantages of low cost and easy installati...

Embodiment 3

[0060] The difference from Embodiment 1 and Embodiment 2 is that in the present invention, each layer of the OLED installation board surface 1 is also provided with a fixing piece 10 for installing the OLED splicing unit, and the fixing piece 10 is a support bar or Installation groove; the OLED splicing unit 2 can also be a soft OLED display screen.

[0061] When the invention is in use, the OLED splicing unit can be further fixed, and the structure is simple, the use is convenient, and the cost is low.

Abstract

The invention discloses an organic light emitting diode (OLED) seamlessly spliced display screen, which comprises a prefabricated mounting plate and a plurality of OLED splicing units. Each OLED splicing unit comprises a luminous display area, an electrode leading-out area, connecting terminals and a driving circuit. Each electrode leading-out area is arranged on the two adjacent side edges of the corresponding luminous display area to form an L-shaped electrode leading-out area. The connecting terminals are arranged on the L-shaped electrode leading-out areas. Prefabricated slots are formed in the L-shaped electrode leading-out areas. The driving circuits are arranged on the back surfaces of the OLED splicing units. The OLED splicing units are arranged on the prefabricated mounting plate, and are spliced through the prefabricated slots to form OLED display modules. The OLED display modules are arranged in a manner of M rows multiplied by N columns to form the combined OLED display screen. The OLED splicing units can be seamlessly spliced, so that the connectivity and the integrity of a picture can be ensured; the display screen is easy to manufacture and low in cost, and the batch production rate of the product is increased; and the display screen is widely applicable and high in portability.
