Description

Technical Field

[0001] The invention relates to the technical field of organic electroluminescence, and in particular to a transparent flexible active organic electroluminescence coupled waveguide optical structure. Background Art

[0002] Organic electroluminescence refers to the luminescence phenomenon produced by small organic molecules or polymer films under the action of an electric field. The luminescence mechanism is that under the action of an external electric field, holes and electrons are injected into the organic material respectively, and they meet and recombine in the organic layer to form excitons, releasing energy. This energy is transferred to the molecules of the organic luminescent material, causing them to transition from the ground state to the excited state. Due to the instability of the excited state, the excited molecules will undergo a radiative transition, returning from the excited state to the ground state, and luminescence will occur in the process.

[0064] Buffer block 7: installed in the middle of the slot area top plate 8 and the slot area bottom plate 10, used to relieve thermal expansion stress at high temperature.

[0065] The present invention relates to a transparent flexible active organic electroluminescent coupled waveguide optical structure, which is mainly used to improve the optical coupling efficiency between optical waveguides and solve the problem of low optical power output caused by the refractive index difference between the core layer and the cladding layer in traditional organic electroluminescent devices. The present invention combines liquid crystal adjustable microlens elements, slot area top and bottom plates, flexible screens, and a variety of support and buffer structures through innovative design to achieve efficient transmission and coupling of light. The actual use process of the present invention will be described in detail below.

[0066] First, you need to prepare the base layer 1 and the light-emitting layer 2, making sure that both are clean and free of impurities, and have a flat surface. Connect the base layer 1 and the light-emitting layer 2 together with an adhesive or other fixing method to ensure that the connection is firm and the sealing is good. This step is the basis of the entire structure. The light-emitting effect of the light-emitting layer 2 will directly affect the subsequent transmission and coupling of light waves.

[0067] The slot area top plate 8 and the slot area bottom plate 10 are installed on the top and bottom of the base layer 1 and the light-emitting layer 2, respectively. The installation of the slot area top plate 8 and the bottom plate 10 must ensure accurate position, and the parallelism and verticality between the two meet the design requirements. The top plate 8 and the bottom plate 10 not only provide the necessary support for the structure, but also form a slot area, providing space for the subsequent installation of light guide strips and light guide columns.

[0068] A flexible screen 6 is installed between the slot area top plate 8 and the slot area bottom plate 10. The flexible screen 6 needs to be laid flat to ensure that it fits tightly with the slot area top plate 8 and the bottom plate 10 to avoid bubbles or wrinkles. The introduction of the flexible screen 6 allows the entire structure to have good flexibility while maintaining transparency, and is suitable for a variety of application scenarios.

[0069] In the slot area between the flexible screen 6 and the light-emitting layer 2, vertical light guide bars 3 and horizontal light guide bars 4 are installed. The vertical light guide bars 3 and horizontal light guide bars 4 are arranged in a cross shape to form a grid structure. This layout is conducive to the uniform transmission and coupling of light waves in all directions. During installation, it is necessary to ensure that the shape of the connecting end of the light guide bar matches the outer contour of the light-emitting layer 2 and the flexible screen 6 to ensure smooth transmission of light waves.

[0070] A light guide column slot 5 is provided at the position where the vertical light guide strip 3 and the horizontal light guide strip 4 are cross-connected. A light guide column connection block 15 is installed at the center of the light guide column slot 5, and then a light guide column 11 is installed on the light guide column connection block 15. The light guide column 11 uses a liquid crystal adjustable microlens element, which can actively improve the refraction of light after power is turned on, thereby enhancing the coupling efficiency of light waves. During installation, it is necessary to ensure that the width of the light guide column 11 is consistent with the width of the light guide column slot 5 to ensure that the installation is stable and the light wave transmission path is unobstructed.

[0071] A slot area top plate plug hole 9 is provided on the slot area top plate 8, and a light guide column block 12 at the top of the light guide column 11 is plugged into the slot area top plate plug hole 9. The slot area top plate plug hole 9 is made of a light-transmitting soft material, with a wall thickness of 2 mm, and a lateral support column 14 is installed on the side wall to enhance the supporting force. The close fit between the light guide column block 12 and the slot area top plate plug hole 9 ensures the stability of the light guide column 11 in the vertical direction.

[0072] A slot area flexible cover plate 13 is installed on the slot area top plate socket 9 to cover and protect the socket and the internal structure. At the same time, a buffer block 7 is arranged in the middle of the slot area top plate 8 and the slot area bottom plate 10 to relieve the thermal expansion stress generated by the optical structure when used at high temperatures. The buffer block 7 includes a buffer block main beam and buffer blades installed on both sides of the main beam. A buffer space is arranged between the buffer blades to effectively absorb and disperse stress.

[0073] After completing the above assembly steps, the entire structure is powered on for testing. First, check whether the connection between the components is firm and reliable, without looseness or falling off. Then turn on the power and observe the luminous effect of the light-emitting layer 2 and the transmission of light waves in the vertical light guide strip 3, the horizontal light guide strip 4 and the light guide column 11. It is also necessary to pay attention to the operation of the light guide column 11, which is the liquid crystal adjustable microlens element. If there is no abnormality, the equipment operates normally, realizing the use of transparent flexible active organic electroluminescent coupled waveguide optical structure.
