Problems solved by technology

like image 3 As shown, when the OLED panels are spliced ​​into a large screen, splicing gaps will be left, and images cannot be displayed in the non-luminous border areas, resulting in discontinuous screen images and affecting viewing effects
Many panel manufacturers are committed to improving the manufacturing process, but only relying on the improvement of the manufacturing process can only narrow the seam as much as possible, but cannot achieve the effect of seamless splicing

Embodiment 1

[0036] like Figure 5 As shown, it is a schematic structural diagram of an OLED display unit in this embodiment; an OLED display unit includes a substrate 7, an OLED module, and an encapsulation layer, and the OLED module is composed of an anode layer 6, an organic layer 5 and a cathode layer 4 stacked on top of each other. , the encapsulation layer is arranged on the periphery and the front surface of the OLED module.

[0037] Wherein the anode layer 6, the organic layer 5, and the cathode layer 4 are sequentially arranged on the substrate 7, that is, the anode layer 6 of the OLED module is arranged on the front of the substrate 7, the organic layer 5 is arranged on the front of the anode layer, and the cathode layer 4 is arranged on the front of the organic layer 5.

[0038] A conductive film is coated on the front side of the substrate 7 and the surrounding side walls 71, wherein the conductive film on one of the substrate side walls 71 is connected to the anode in the OLED...

Embodiment 2

[0046] like Image 6 As shown, this embodiment is similar to Embodiment 1, the difference is that the OLED module adopts an inverted structure, wherein the cathode layer 4, the organic layer 5, and the anode layer 6 are sequentially arranged on the substrate 7, that is, the backside of the cathode layer 4 of the OLED module is arranged on the On the front side of the substrate 7 , the organic layer 5 is arranged on the front side of the cathode layer 4 , and the anode layer 6 is arranged on the front side of the organic layer 5 . The inverted structure of the OLED module changes the light output direction of the OLED display unit, and the image of the OLED display unit is displayed from the anode layer 6 through the encapsulation layer on the front of the anode layer 6. This light output method increases the aperture ratio, thereby increasing the The brightness of the OLED display unit.

Abstract

The invention relates to an OLED (organic light-emitting diode) display technology and specifically relates to an OLED display unit and an OLED spliced display screen with the same. The OLED display unit comprises a substrate and an OLED module arranged on the front surface of the substrate, wherein a packaging layer is arranged on the periphery and the front surface of the OLED module, conductive films are plated on the front surface and the peripheral side walls of the substrate, the conductive film on any one side wall of the substrate is connected with an anode in the OLED module, the conductive film on another side wall of the substrate is connected with a cathode of the OLED module, an anode leading wire and a cathode leading wire are respectively led out of the conductive films on another two side walls of the substrate and connected with an external circuit, and the two side walls of the substrate are externally connected with binding regions. According to the OLED display unit disclosed by the invention, the binding regions of an OLED panel are transferred onto the side walls of the substrate through a packaging surface of the OLED module, so that a non-luminous side frame region of a device is reduced, and the splicing effect of the OLED spliced display screen is optimized.

Description

technical field [0001] The invention relates to an organic light emitting diode (OLED) display technology, in particular to an OLED display unit and an OLED splicing display screen with the display unit. Background technique [0002] OLED has the advantages of all solid state, ultra-thin, no viewing angle limitation, fast response, wide operating temperature, easy to realize flexible display and 3D display, etc., and is considered to be one of the most promising new FPD technologies. At present, the largest OLED screen that can be trial-produced is below 55 inches, and the OLED screens that are commercially put on the market are limited to 5-10 inches, and the size is small. Expensive raw materials. Therefore, how to use existing size OLED panels to further assemble and splice into a large-screen video wall to meet the requirements of large-screen display has become an important issue in this technical field. [0003] According to the requirements of the driving circuit an...
