Description

Technical Field

[0001] This utility model relates to the field of display equipment technology, and in particular to an OLED display module and an OLED display screen. Background Technology

[0002] OLED (Organic Light-Emitting Diode), also known as organic electroluminescent display or organic light-emitting semiconductor, is a device that generates electroluminescence using a multilayer organic thin-film structure. OLED display modules are display modules manufactured using OLED technology. They consist of multiple layers of organic materials and emit light through current-driven illumination. They possess self-emissive properties and do not require a backlight, thus allowing for the creation of thinner and lighter displays. Flexible OLED display modules, in particular, are bendable.

[0003] In existing technologies, the ITO anode, cathode, and organic light-emitting layer of flexible OLED display modules are all designed on a glass substrate, and a polarizer is placed on the other side of the glass substrate through an additional process. However, as the overall design of the flexible OLED display module becomes smaller, the existing flexible OLED display modules are not easy to bend and cannot meet the miniaturization requirements. Utility Model Content

[0004] The purpose of this invention is to provide an OLED display module and an OLED display screen to solve the problem that existing flexible OLED display modules are difficult to bend when the design is smaller, thus failing to meet miniaturization requirements.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] On one hand, this utility model provides an OLED display module, comprising:

[0007] Polarizing layer;

[0008] An ITO anode layer is disposed on the polarizing layer;

[0009] An organic light-emitting layer is disposed on the ITO anode layer;

[0010] A cathode layer is disposed on the organic light-emitting layer;

[0011] An encapsulation film layer covers the cathode layer.

[0012] As an optional solution for the above-mentioned OLED display module, the OLED display module further includes a protective adhesive layer, which is coated on the outside of the encapsulation film layer.

[0013] As an optional solution for the aforementioned OLED display module, the protective adhesive layer is a waterproof membrane.

[0014] As an alternative to the aforementioned OLED display module, the OLED display module further includes an encapsulation cover, which is disposed on the polarizing layer and covers the encapsulation film layer.

[0015] As an alternative solution for the aforementioned OLED display module, a drying element is provided on the encapsulation cover, and the drying element is located between the encapsulation cover and the encapsulation film layer.

[0016] As an alternative to the aforementioned OLED display module, the OLED display module further includes a driving chip, which is disposed on the polarizing layer and electrically connected to the ITO anode layer or the cathode layer.

[0017] As an alternative to the aforementioned OLED display module, the OLED display module further includes an FPC component, which is disposed on the polarizing layer and electrically connected to the driving chip.

[0018] As an alternative to the aforementioned OLED display module, the encapsulation film, the driving chip, and the FPC component are arranged sequentially at intervals.

[0019] As an optional solution for the aforementioned OLED display module, the polarizing layer is a PET polarizer.

[0020] On the other hand, the present invention provides an OLED display screen, including the OLED display module as described above.

[0021] The beneficial effects of this utility model are as follows:

[0022] This OLED display module includes a polarizing layer, an ITO anode layer, an organic light-emitting layer, a cathode layer, and an encapsulation film layer. The ITO anode layer is disposed on the polarizing layer, the organic light-emitting layer is disposed on the ITO anode layer, the cathode layer is disposed on the organic light-emitting layer, and the encapsulation film layer covers the cathode layer. This OLED display module directly places the ITO anode layer, organic light-emitting layer, and cathode layer on the polarizing layer as a whole, and then covers the cathode layer with the encapsulation film layer. This reduces the amount of glass substrate used, reduces the overall thickness of the OLED display module, and improves its flexibility and bending capability, thereby meeting the miniaturization requirements of the OLED display module. At the same time, by reducing the amount of glass substrate used, materials are saved, and the original process of attaching the polarizing layer to the glass substrate is eliminated, thereby reducing production costs.

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides an OLED display module that can be flexibly bent.

[0032] This OLED display module includes a polarizing layer 1, an ITO anode layer 2, an organic light-emitting layer 3, a cathode layer 4, and an encapsulation film layer 5. The ITO anode layer 2 is disposed on the polarizing layer 1, the organic light-emitting layer 3 is disposed on the ITO anode layer 2, the cathode layer 4 is disposed on the organic light-emitting layer 3, and the encapsulation film layer 5 covers the cathode layer 4. This OLED display module directly places the ITO anode layer 2, the organic light-emitting layer 3, and the cathode layer 4 onto the polarizing layer 1, and then covers the cathode layer 4 with the encapsulation film layer 5. This reduces the amount of glass substrate used, lowers the overall thickness of the OLED display module, and improves its flexibility and bending capability, thus meeting the miniaturization requirements of the OLED display module. Simultaneously, by reducing the amount of glass substrate used, materials are saved, and the original process of attaching the polarizing layer 1 to the glass substrate is eliminated, thereby reducing production costs. The polarizing layer 1 is used to convert the light emitted by the organic light-emitting layer 3 into soft light acceptable to the human eye, thereby preventing glare. Optionally, the polarizing layer 1 is a PET polarizing film. The PET polarizing film has a certain strength and folding resistance, and can be used as a substrate for support, and realize the flexible bending of the OLED display module.

[0033] Furthermore, the OLED display module also includes a protective adhesive layer 6, which is coated on the outside of the encapsulation film layer 5 and can completely cover the encapsulation film layer 5 to effectively protect the internal display device. Optionally, the protective adhesive layer 6 is a waterproof film, thereby protecting the adhesive layer 6 from water and oxygen, preventing or prolonging the time for water and oxygen to enter the display device, and extending the service life of the OLED display module.

[0034] Furthermore, the OLED display module also includes an encapsulation cover 7, which is disposed on the polarizing layer 1 and covers the encapsulation film layer 5. By providing the encapsulation cover 7, water and oxygen can be isolated, preventing them from entering the interior of the display device. A drying element 71 is provided on the encapsulation cover 7, located between the encapsulation cover 7 and the encapsulation film layer 5, to absorb moisture entering the space between the encapsulation cover 7 and the encapsulation film layer 5, thereby extending the lifespan of the OLED display module. Optionally, the edge of the encapsulation cover 7 is fixed to the polarizing layer 1 by adhesive.

[0035] Furthermore, the OLED display module also includes a driver chip 8, which is disposed on the polarizing layer 1 and electrically connected to the ITO anode layer 2 or cathode layer 4 to control the operation of the OLED display module. Simultaneously, the OLED display module also includes an FPC component 9, which is disposed on the polarizing layer 1 and electrically connected to the driver chip 8, allowing the OLED display module to be electrically connected to external connection devices via the FPC component 9. Optionally, the encapsulation film layer 5, the driver chip 8, and the FPC component 9 are arranged sequentially at intervals to facilitate wiring on the polarizing layer 1, reduce the difficulty of electrically connecting the driver chip 8 to the ITO anode layer 2 or cathode layer 4, and reduce the difficulty of electrically connecting the FPC component 9 to the driver chip 8.

[0036] This embodiment also provides an OLED display screen, including the OLED display module as described above. By using the OLED display module as described above, the glass substrate can be reduced, the overall thickness of the OLED display screen can be reduced, and the flexible bending capability can be improved, thereby meeting the requirement of miniaturization of the OLED display screen.
