[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0037] Quantum dot light-emitting diodes (QLEDs) are an emerging display device with a structure similar to OLEDs (Organic Light-Emitting Diodes), consisting of a sandwich structure of a hole transport layer, an emissive layer, and an electron transport layer. QLEDs represent a novel technology between liquid crystal displays (LCDs) and OLEDs, with the core technology being "quantum dots," which are composed of zinc, cadmium, selenium, and sulfur atoms.

[0038] Quantum dots emit light over a very narrow wavelength range and produce pure, adjustable colors, resulting in clearer and brighter images compared to LCD displays. Currently, the functional layers of quantum dot light-emitting devices are fabricated using spin coating or printing methods. Spin coating results in poor overall uniformity, while printing requires humidification to improve device performance. However, humidification introduces black spots, significantly hindering subsequent illumination and frequently causing fluorescence quenching during testing. These issues severely restrict the research and development of quantum dot light-emitting devices.

[0039] Please see the appendix Figure 1 To be continued Figure 4 A humidifier box, the humidifier box 100 comprising:

[0040] First-stage filter 1;

[0041] The second-stage filter 2 is stacked inside the humidification box 100, consisting of the first-stage filter 1 and the second-stage filter 2.

[0042] By setting the first-stage filter and the second-stage filter 2 vertically, the light-emitting device can be uniformly humidified to improve the display uniformity of the light-emitting device.

[0043] As attached Figure 1 To be continued Figure 4 As shown, furthermore, in the thickness direction of the first-stage filter 1 and the second-stage filter 2, the filter holes of the first-stage filter 1 and the second-stage filter 2 are misaligned. By vertically aligning the first-stage filter and the second-stage filter 2 and misaligning the filter holes of the first-stage filter 1 and the second-stage filter 2, uniform humidification treatment can be performed on the light-emitting device to improve the display uniformity of the light-emitting device.

[0044] To elaborate further, misalignment means that in the thickness direction of the first-stage filter 1 and the second-stage filter 2, the filter holes of the first-stage filter 1 and the second-stage filter 2 are not completely aligned. Instead, there is a certain offset or misalignment between the filter holes of the first-stage filter 1 and the filter holes of the second-stage filter 2. That is, when viewed from the thickness direction of the first-stage filter 1 and the second-stage filter 2, the filter holes of the first-stage filter 1 and the filter holes of the second-stage filter 2 may partially overlap or not overlap.

[0045] As attached Figure 1 To be continued Figure 4 As shown, further, the orthographic projection of the filter pores of the first-stage filter 1 onto the second-stage filter 2 is located between the filter pores on the second-stage filter 2. This ensures that after moisture passes through the first-stage filter 1, it is blocked by the second-stage filter 2, which not only slows down the propagation speed of the moisture but also allows the moisture to evenly fill the entire humidification box 100, improving humidification uniformity. This provides uniform humidification for the light-emitting device, eliminates black spots generated by the printed film deposition method, reduces the probability of fluorescence quenching, and reduces leakage current, thereby improving the luminous uniformity of the light-emitting device.

[0046] Furthermore, in this embodiment, the aforementioned misalignment means that the orthographic projection of the filter holes of the first-stage filter 1 onto the second-stage filter 2 does not overlap with the filter holes on the second-stage filter 2.

[0047] As attached Figure 1 To be continued Figure 4 As shown, the first-stage filter 1 further includes a first filtration zone 11 and a first closed zone 12. The first closed zone 12 is located on the outer periphery of the first filtration zone 11, and the filter holes of the first-stage filter 1 are disposed on the first filtration zone 11.

[0048] The second-stage filter 2 includes a second filtration zone 21, a second closed zone 22, and a third closed zone 23. The second closed zone 22 is located on the outer periphery of the second filtration zone 21, and the second filtration zone 21 is located on the outer periphery of the third closed zone 23. The filter holes on the second-stage filter 2 are arranged on the second filtration zone 21, and the orthographic projection of the first filtration zone 11 on the second-stage filter 2 is located on the third closed zone 23. After passing through the first-stage filter 1, the moisture will move towards the third closed area 23. When it comes into contact with the third closed area 23, it will be blocked by the third closed area 23 and thus diffuse to the surrounding area. At the same time, the moisture is also blocked by the second closed area 22. The moisture can only pass through the filter holes of the second filter area 21. Setting multiple closed areas can not only slow down the propagation speed of moisture, but also make the moisture evenly fill the entire humidification box 100, improve the humidification uniformity, perform uniform humidification treatment on the light-emitting device, eliminate black spots generated by the printing film method of the device, reduce the probability of fluorescence quenching and reduce leakage current, thereby improving the light emission uniformity of the light-emitting device.

[0049] Furthermore, the shape of the first filter area 11 is the same as that of the third closed area 23, although they can also be set to different shapes. In this embodiment, the first filter area 11 and the third closed area 23 are both circular, and the diameter of the third closed area 23 is greater than or equal to the diameter of the first filter area 11, thereby improving the effect of blocking the movement of moisture.

[0050] As attached Figure 1 To be continued Figure 4 As shown, the humidification box 100 is further provided with a third-stage filter 3. In the stacking direction of the first-stage filter 1 and the second-stage filter 2, the third-stage filter 3 is located on the side of the second-stage filter 2 away from the first-stage filter 1. The third-stage filter 3 is configured as a full filtration area structure. Adding the third-stage filter 3 can further slow down the propagation speed of moisture, so that moisture can evenly fill the entire humidification box 100, improve the humidification uniformity, and perform uniform humidification treatment on the light-emitting device.

[0051] As attached Figure 1 To be continued Figure 4As shown, the humidification box 100 further includes a heating module 5, which is used to place the device to be humidified. A first propagation space 10 is formed between the first-stage filter 1 and the second-stage filter 2, a second propagation space 20 is formed between the second-stage filter 2 and the third-stage filter 3, and a humidification space 30 is formed between the third-stage filter 3 and the heating module 5. Moisture passes through the first-stage filter 1, the first propagation space 10, the second-stage filter 2, the second propagation space 20, and the third-stage filter 3 in sequence, and then uniformly fills the humidification space 30. The heating module 5 is used to heat the device to be humidified, promote the reaction process of the light-emitting device, improve efficiency and stabilize performance. At the same time, the multi-layer filter can further slow down the propagation speed of moisture, so that the moisture uniformly fills the entire humidification space 30, so that the moisture uniformly humidifies the device, improves the humidification uniformity, and the moisture passivates the defect state of the light-emitting device, thus uniformly humidifying the light-emitting device.

[0052] Furthermore, the first-stage filter 1 is circular or square, the second-stage filter 2 and the third-stage filter 3 are square, and the second-stage filter 2 and the third-stage filter 3 are square structures with a side length of 45mm. The diameter of the first filtration zone 11 is 15mm, the diameter of the third closed zone 23 is 20mm, and the second filtration zone 21 is an annular structure with an outer diameter of 40mm and an inner diameter that is the same as the diameter of the third closed zone 23.

[0053] Furthermore, the heating module 5 includes a platform 51 for placing the humidified device, a heating plate 52 and a heat probe 53 disposed within the platform 51. The number of heat probes 53 is 6 to 80, and the number of probes can be determined according to the size of the platform 51. The distribution of the heat probes 53 can be random or arrayed. The platform 51 is also provided with grooves for placing the heat probes 53, and the size of the grooves ranges from (30mm*30mm) to (200mm*200mm). The distance between the heating plate 52 and the end face of the platform 51 is 5mm.

[0054] As attached Figure 1 To be continued Figure 4 As shown, the humidifier box 100 further includes an adjustment unit 6;

[0055] The adjustment unit 6 is used to move the adjustment units 6 of the second-stage filter 2 and the third-stage filter 3 to adjust the distance between the first-stage filter 1 and the second-stage filter 2, and / or adjust the distance between the second-stage filter 2 and the third-stage filter 3. By adjusting the distance between the first-stage filter 1 and the second-stage filter 2, the distance between the second-stage filter 2 and the third-stage filter 3, and the distance between the third-stage filter 3 and the humidified device, the propagation speed of moisture can be adjusted in real time, so that moisture evenly fills the entire humidification space 30.

[0056] Furthermore, the distance between the first-stage filter 1 and the second-stage filter 2 is 5mm to 40mm, and the distance between the second-stage filter 2 and the third-stage filter 3 is 3mm to 10mm. Of course, the adjustment unit 6 can also adjust the distance between the heating module 5 and the third-stage filter 3, with the adjusted distance ranging from 3mm to 60mm.

[0057] As attached Figure 1 To be continued Figure 4 As shown, the first-stage filter 1, the second-stage filter 2, and the third-stage filter 3 are each provided in two layers, and the pore sizes of the two layers of the first-stage filter 1 are different, as are the pore sizes of the two layers of the second-stage filter 2. This multi-layered filter arrangement forces moisture to pass through multiple layers, further slowing down the propagation speed of moisture and ensuring that moisture evenly fills the entire humidification space 30. This allows for uniform humidification of the humidified device, improving humidification uniformity. The moisture also passivates defect states in the light-emitting device, resulting in uniform humidification.

[0058] As attached Figure 1 To be continued Figure 4 As shown, furthermore, the pore sizes of the two first-stage filter screens 1 are independently selected from 200μm to 400μm and 10μm to 60μm, respectively; the pore sizes of the two second-stage filter screens 2 are independently selected from 200μm to 400μm and 10μm to 60μm, respectively; and the pore size of the third-stage filter screen 3 is 10μm to 30μm. Setting appropriate pore sizes can filter moisture, slow down the propagation speed of moisture, and ensure that moisture evenly fills the entire humidification space 30.

[0059] It is understood that the pore sizes of the upper first-stage filter 1 and the upper second-stage filter 2 are any value or any two of 200μm, 300μm, and 400μm; the pore sizes of the lower first-stage filter 1 and the lower second-stage filter 2 are any value or any two of 10μm, 20μm, 30μm, 40μm, 50μm, and 60μm; and the pore sizes of the third-stage filter 3 are any value or any two of 10μm, 20μm, and 30μm. The two first-stage filter 1 layers and the two second-stage filter 2 layers can each have pores of the same or different diameters.

[0060] As attached Figure 1 To be continued Figure 4 As shown, the humidification box 100 is further provided with a humidification pipe 4, and the first-stage filter 1 is disposed on the humidification pipe 4. The two ends of the humidification pipe 4 are respectively connected to an air inlet 41 and an exhaust outlet 42. The air inlet 41 and the exhaust outlet 42 can adjust the air flow rate and speed to slow down the propagation speed of moisture, so that the moisture evenly fills the entire humidification space 30.

[0061] Furthermore, the first-stage filter 1, the second-stage filter 2, the third-stage filter 3, and the humidification pipe 4 form a humidification assembly. The humidification pipe 4 has a U-shaped structure and a diameter of 15mm to 30mm. The humidification assembly and the heating module 5 are connected by a lead screw assembly 43 and a motor to open and close, thereby allowing the humidified device, i.e., the light-emitting device, to be placed or removed. A sealing strip 44 is also provided between the humidification assembly and the heating module 5, ensuring excellent sealing of the humidification environment. This sealing performance eliminates the influence of oxygen on the humidification environment and can exclude interference from other unnecessary factors.

[0062] Please see the appendix Figure 5 Based on the aforementioned humidifier box 100, this application embodiment also provides a humidification device, comprising: a humidification device body 200, a moving component 300, a gas component 400, and multiple humidifier boxes 100. Each humidifier box 100 is disposed on the moving component 300, and the gas component 400 is connected to the humidifier box 100. By misaligning the filter holes of the first-stage filter 1 with those of the second-stage filter 2, uniform humidification can be applied to the light-emitting device, thereby improving the display uniformity of the light-emitting device. The humidification device provides a highly uniform humidification environment, and each humidifier box 100 is independent, allowing for control of different humidity levels and temperatures. The humidification environment has excellent sealing properties, eliminating the influence of oxygen on the humidification environment and preventing interference from other unnecessary factors.

[0063] Furthermore, the number of humidification boxes 100 is 2 to 36, and the size of the humidification boxes 100 ranges from (100mm×100mm×150mm) to (400mm×400mm×200mm). The humidification boxes 100 can simulate the environment in which the product is located (such as high temperature, inert gas, high humidity environment, etc.) for life testing. One humidification box 100 can simultaneously test 36 different humidified devices or humidified devices under multiple experimental conditions without interference. The humidification boxes are detachable, which facilitates the loading and unloading of the substrate, improves personnel work efficiency, and also increases experimental efficiency.

[0064] Furthermore, the humidifier body 200 includes a housing 7, a cavity door 8, and a control assembly 13. The cavity door 8 is sealed to the housing 7 via a snap-fit ​​connection. The volume of the humidifier cavity within the housing 7 ranges from (6000mm × 6000mm × 4000mm) to (8000mm × 8000mm × 4000mm). The cavity door 8 is fixedly connected to a support platform 9. The moving assembly 300 includes a support platform 9 for placing the humidifier box 100 and a slide rail 91. The support platform 9 is connected via... The slide rail 91 is movably connected to the housing 7, so that pulling the cavity door 8 can pull out the support platform 9 located inside the housing 7, thereby exposing the humidification box 100, and thus allowing the humidified device to be placed or removed. The slide rail 91 includes pulleys and guide rails. The pulleys are symmetrically arranged vertically, with 9 to 15 pulleys evenly distributed on both the top and bottom. The guide rail is a T-shaped slide rail, which is arranged between the pulleys to prevent the support platform 9 from falling off when it is pulled out. The gas assembly 400 can independently supply humidifying N2 gas or pure N2 gas to the humidification pipe 4.

[0065] During humidification, several unencapsulated top-emitting QLED light-emitting devices with spin-coated or printed electron transport layers are first provided, i.e., the devices to be humidified; then, the housing 7 is inflated to break the vacuum, and the humidification box 100 is opened through the control component 13; several light-emitting devices are placed in the stage 51, the cavity door 8 is closed, and then a vacuum is drawn and pure nitrogen (N2) gas is introduced, repeating this process 4-5 times; then, the humidification component and the heating module 5 are closed through the control component 13; the positions of the second-stage filter 2 and the third-stage filter 3 are adjusted through the adjustment unit 6; then, humidifying N2 gas can be introduced, and the air inlet 41 and the exhaust port 42 are opened in sequence, the valve size can be adjusted according to experimental requirements; the humidification time is 45 min to 5 h, and the time can be adjusted according to the humidity level; after humidification, the spin-coated or inkjet-printed wafers are transferred to a high-vacuum evaporation or sputtering equipment, and under a pressure of 10-5 Pa, the cathode is heated to ~ Deposition at a rate of [missing information], and then at [missing information] The adsorption layer was deposited at a high rate; then encapsulated with encapsulating adhesive and a cover plate, and the sample was encapsulated with UV-curable resin (Pulse Puretone 20-001) and stored in a pure N2 gas environment; subsequently, the encapsulated device was heated to 145℃ for 30 min as a post-treatment; the device was moved to a microscope for imaging to check the uniformity of light emission and whether black spots were generated; at the same time, the device's operating life data was tested using a constant current drive of 63.7mA / cm2 to determine the device's operating life, and the JVL data of the device was tested to determine the device's electrical performance.

[0066] As attached Figure 6 As shown in (b), if the light-emitting device is humidified using existing technology, black spots will appear on the device, affecting light emission and causing uneven light emission. (See attached image.) Figure 6 As shown in (a), the method of this application can be used to uniformly humidify the light-emitting device, which can eliminate black spots generated by the printing film method, reduce the probability of fluorescence quenching and reduce leakage current, thereby improving the light emission uniformity of the light-emitting device.
