Definitions
- the invention belongs to a light-emitting structure or display device based on the principle of electroluminescence.
- Chinese patent CN201010101273.7 provides a flexible matrix inorganic electroluminescent flat panel display comprising a transparent plastic base layer, a stacked lateral transparent conductive stripe layer, a luminescent layer, a dielectric layer, and a vertical layout which are sequentially arranged on a transparent plastic base layer.
- the through electrode on the display is connected to the conductive stripe layer, and the back electrode is connected to the back electrode strip layer.
- the electrodes, electroluminescent materials, various dielectric layers and auxiliary layer structures in the patent are directly prepared on a whole flat substrate (glass or plastic substrate), which is an overall structure, and the size of the display is directly dependent on the substrate size.
- the large-area flat substrate processing has high requirements on equipment, environment and processing technology, and the processing technology is also very complicated, so there are disadvantages such as large screen difficulty, high equipment requirements, and high realization cost.
- Electrodes, electroluminescent materials, various dielectric layers, and auxiliary layer structures are all in parallel stacked structures on a flat substrate.
- the electric field concentration is poor, and the luminance and luminous efficiency are low.
- each color light-emitting lattice structure needs to be performed on a flat substrate by using a mask evaporation or deposition, or a complicated processing process such as mask printing, mask exposure, mask etching, and the like.
- the process precision is high and difficult, resulting in high equipment and production environment requirements, large investment, low yield and high cost.
- the preparation of the light-emitting layer requires a paste printing or coating and sintering process, which is limited by the hot working temperature, and requires the use of a heat-resistant hard substrate (such as glass), which cannot be realized. Flexible, it is difficult to enlarge the screen.
- the preparation of the light-emitting layer requires vacuum deposition or growth process, which requires high process environment and equipment, and has the disadvantages of large investment, low yield and high cost.
- the electroluminescent material layer is a film.
- the preparation of the luminescent layer requires vacuum deposition or growth process.
- the organic luminescent material is very sensitive to water and oxygen, and the requirements for the permeability of the substrate material and the sealing technology are strict, which leads to The production process environment and processing equipment have high requirements, and have the disadvantages of large investment, low yield, and high cost.
- the present invention provides a new structure of a light-emitting structure or a display device, which solves the above problems by using separate light-emitting line unit structures independent of each other.
- a light-emitting structure based on the principle of electroluminescence which is characterized in that it comprises: a first supporting component and a light-emitting filament unit, wherein the first supporting component comprises a thin supporting substrate and a substrate functional unit, and the substrate functional unit comprises Preparing or coating at least one layer of scan electrodes and fixing components on the thin support substrate;
- the light emitting filament unit is fixed on the first supporting component by a fixing component
- the luminescent filament unit comprises an array of filaments formed by rewinding or arranging or weaving at least one luminescent filament.
- the second support assembly includes a thin support substrate and a substrate function unit, and the substrate functional unit includes at least one scanning electrode and a fixing assembly sequentially prepared or coated on the thin support substrate;
- the light emitting filament unit is fixed between the first support assembly and the second support assembly.
- the above fixing member is at least one layer of bonding material prepared, coated on the scanning electrode, a layer of a low-melting heat sealing material, a riveting structure or a snap structure.

Description
一种基于电致发光原理的发光结构及显示器件 技术领域 Light-emitting structure and display device based on electroluminescence principle
本发明属于一种基于电致发光原理的发光结构或显示器件。 The invention belongs to a light-emitting structure or display device based on the principle of electroluminescence.
背景技术 Background technique
平板发光显示器作为信息技术的终端线设备， 已经广泛用于移动电话、 电 视机、 计算机等。 如中国专利 CN201010101273.7 提供了一种柔性矩阵无机 电致发光平板显示器， 包括透明塑料基础层、 依次布局在透明塑料基础层上的 堆叠的横向透明导电条纹层、 发光层、 介质层、 纵向布局的背电极条纹层、 保 护层以及塑料薄膜。 显示器上的透电极与导电条纹层连接， 背电极与背电极条 纹层连接。 虽然上述结构的显示器解决的动态显示的问题， 但是还是存在下列 几个问题： As a terminal line device for information technology, flat panel light-emitting displays have been widely used in mobile phones, televisions, computers, and the like. For example, Chinese patent CN201010101273.7 provides a flexible matrix inorganic electroluminescent flat panel display comprising a transparent plastic base layer, a stacked lateral transparent conductive stripe layer, a luminescent layer, a dielectric layer, and a vertical layout which are sequentially arranged on a transparent plastic base layer. The back electrode stripe layer, the protective layer and the plastic film. The through electrode on the display is connected to the conductive stripe layer, and the back electrode is connected to the back electrode strip layer. Although the display of the above structure solves the problem of dynamic display, there are still several problems:
1、 该专利中的电极、 电致发光材料和各种介质层以及辅助层结构都是直 接制备在一整张平板基板（玻璃或塑料基板）上， 是整体结构， 显示器尺寸直 接取决于基板尺寸， 而大面积的平板基板整体加工对设备、 环境和处理工艺的 要求都很高， 加工工艺也很复杂， 因此存在大画面化困难、 设备要求高、 实现 成本高等缺点。 1. The electrodes, electroluminescent materials, various dielectric layers and auxiliary layer structures in the patent are directly prepared on a whole flat substrate (glass or plastic substrate), which is an overall structure, and the size of the display is directly dependent on the substrate size. The large-area flat substrate processing has high requirements on equipment, environment and processing technology, and the processing technology is also very complicated, so there are disadvantages such as large screen difficulty, high equipment requirements, and high realization cost.
2、 电极、 电致发光材料和各种介质层以及辅助层结构都采用的是在平板 基板上的平行堆叠结构， 电场集中性差， 发光亮度和发光效率较低。 2. Electrodes, electroluminescent materials, various dielectric layers, and auxiliary layer structures are all in parallel stacked structures on a flat substrate. The electric field concentration is poor, and the luminance and luminous efficiency are low.
3、 各色发光点阵结构的制备需要使用掩模蒸镀或沉积， 或者掩模印刷、 掩模曝光、 掩模蚀刻等复杂加工工艺， 逐层堆叠制备在平板基板上。 工艺精度 要求高、 难度大， 导致设备和生产环境要求高、 投资大， 以及良品率低、 成本 高等缺点。 3. The preparation of each color light-emitting lattice structure needs to be performed on a flat substrate by using a mask evaporation or deposition, or a complicated processing process such as mask printing, mask exposure, mask etching, and the like. The process precision is high and difficult, resulting in high equipment and production environment requirements, large investment, low yield and high cost.
4、 使用分散粉体类型电致发光材料的显示器， 发光层的制备需要浆料印 刷或涂敷以及烧结工艺，受到热加工温度的限制，需要使用耐热的硬性基板（如 玻璃）， 无法实现柔性化， 难以大画面化。 4. Using a display that disperses a powder type electroluminescent material, the preparation of the light-emitting layer requires a paste printing or coating and sintering process, which is limited by the hot working temperature, and requires the use of a heat-resistant hard substrate (such as glass), which cannot be realized. Flexible, it is difficult to enlarge the screen.
5、 使用薄膜或者厚膜电致发光材料层的显示器， 发光层的制备需要使用 真空沉积或生长工艺， 对工艺环境和设备要求很高， 存在投资大、 良品率低、 成本高等缺点。
6、 电致发光材料层为薄膜， 发光层的制备需要使用真空沉积或生长工艺， 另外有机发光材料对水和氧气十分敏感，对基板材料的透气率以及密封技术的 要求都很严格， 这导致生产工艺环境和处理设备的要求高， 存在投资大、 良品 率低、 成本高等缺点。 5. For the display using thin film or thick film electroluminescent material layer, the preparation of the light-emitting layer requires vacuum deposition or growth process, which requires high process environment and equipment, and has the disadvantages of large investment, low yield and high cost. 6. The electroluminescent material layer is a film. The preparation of the luminescent layer requires vacuum deposition or growth process. In addition, the organic luminescent material is very sensitive to water and oxygen, and the requirements for the permeability of the substrate material and the sealing technology are strict, which leads to The production process environment and processing equipment have high requirements, and have the disadvantages of large investment, low yield, and high cost.
7、 使用有机发光材料， 当使用柔性塑料基板时， 难以保证全面范围内的 透气率和封装质量， 会导致材料迅速劣化， 出现寿命短和良品率低等问题； 当 使用透气率低和易于密封的玻璃基板时， 又难于实现柔性化。 7. When using organic light-emitting materials, when using flexible plastic substrates, it is difficult to ensure the air permeability and package quality in a comprehensive range, which will lead to rapid deterioration of materials, short life and low yield; when using low air permeability and easy to seal When the glass substrate is used, it is difficult to achieve flexibility.

The present invention uses a separate, independent light-emitting filament to be arranged or woven together to form an array of light-emitting filaments to form a light-emitting lattice, instead of the conventional method of integrally processing a light-emitting lattice on a flat substrate, the processing unit Changing from a large-area flat substrate to a filament structure greatly reduces process complexity and equipment complexity. And the size of the final illuminating or display device depends on the number of arranging/weaving of the illuminating filaments, and the size of the device can be easily freely expanded without limitation.

In order to further improve the driving electric field concentration and the luminous area coverage, the present invention prepares a light-transmissive or transparent annular electrode at a position on the surface of the light-emitting filament that contacts the scanning electrode, and corresponds to a position on the thin supporting substrate. The scanning electrodes are connected to each other, or the upper and lower support members are used to make the scanning electrode surround the central axis core data electrode of the light-emitting filament in a 360-degree annular shape.

Under the conditions, the service life can be obtained much longer than the conventional electroluminescent line structure. The luminescent lifetime varies from thousands of hours to tens of thousands of hours depending on the luminescent material and the driving frequency.

7、 当使用稳定性高的无机发光材料时， 不会发生类似有机发光材料遇水 和氧迅速劣化的问题， 具有优于现有有机电致发光结构的环境稳定性。 7. When a highly stable inorganic luminescent material is used, the problem that the organic luminescent material is rapidly deteriorated with water and oxygen does not occur, and the environmental stability is superior to that of the existing organic electroluminescent structure.
8、 当使用有机发光材料时， 可以方便地在具有很小表面积的二维发光细 丝的表面覆盖或涂敷保护薄膜或者设置保护壳层等辅助层，避免发光材料遇水 和氧劣化，将有机发光材料密封保护起来，可以兼顾柔性、发光寿命和良品率， 获得优于现有有机电致发光结构的环境稳定性。 8.

路的对应接口相连。横向排列的网纹状长方条带为印制在薄型支撑基板上的扫 描电极， 与扫描电路的对应接口相连。 此处， 如果扫描电极材料是透明导电材 料， 则不需要形成网纹图案； 如果使用的是不透明的导体材料， 则需要形成网 纹图案以获得足够的透光率。 另外， 为了降低电阻， 保证全屏范围内电压或电 流信号的一致性， 扫描电极上可以制备有总线电极。 FIG. 11 is a schematic view showing the principle of illumination of the light-emitting structure of the present invention. The elongated cylindrical shape arranged vertically is a light-emitting filament, and the core of the light-emitting filament is a conductive filament, which is used as a data electrode and a data electrode. The corresponding interfaces of the roads are connected. The transversely arranged web-shaped rectangular strips are scan electrodes printed on the thin support substrate and connected to corresponding interfaces of the scanning circuit. Here, if the scan electrode material is a transparent conductive material, it is not necessary to form a textured pattern; if an opaque conductive material is used, it is necessary to form a textured pattern to obtain sufficient light transmittance. In addition, in order to reduce the resistance and ensure the consistency of the voltage or current signal in the full screen range, a bus electrode can be prepared on the scan electrode.

The curve, c curve is the charge density c/cm 2 ) curve. The luminescent material will only illuminate when the voltage exceeds a certain threshold Vth. As the driving voltage increases, the luminance of the light rises rapidly and gradually becomes saturated. The vertically aligned light-emitting filaments and the laterally aligned scan electrodes intersect to form a matrix structure. When a driving voltage applied to the luminescent material at the junction point exceeds a threshold voltage by the data electrode in the light-emitting filament and the scanning electrode on the thin supporting substrate, respectively, the point emits light of a certain brightness. Therefore, the matrix scanning of the light-emitting lattice can be formed by the control circuit modulating the matching of the driving signals on the data electrodes and the scanning electrodes, and further combining to form an image display having a certain gray level. Here, the front and rear electrodes may be directly crossed to form a passive matrix structure, or may be an active matrix structure using a TFT.
