Description

Technical Field

[0001] The present application relates to the field of display technologies, and in particular, to a display panel and a display device having the display panel. Background Art

[0002] As a self-luminous structure, OLED (Organic Light-Emitting Diode) has been increasingly widely used in display products such as smart phones, wearable devices, tablets, computers, and televisions. The OLED display panel has advantages such as a wide viewing angle, high contrast ratio, low power consumption, high brightness, and flexible display, and has become the mainstream product in the current display field. In order to reduce the reflectivity of external light in the OLED display panel, a circular polarizer generally needs to be attached to the light-emitting surface of the OLED device, but the circular polarizer will cause a large light-emitting loss. Another solution is the POL-less technology, which is a new technology to replace the polarizer represented by COE (Color film on Encapsulation), and the light-emitting efficiency can be improved through the color filter relative to the polarizer, which can greatly increase the light-emitting brightness.

[0003] However, when the OLED display panel is stretched, due to the difference in the elastic coefficients of different film layers of the display panel, a corresponding deformation displacement may occur between the light-emitting layer and the color-resist layer located above it, resulting in a decrease in the light intensity of the deformed display screen, and misalignment and display abnormality may occur during normal display of the screen, resulting in a poor viewing experience for users.

[0032] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic diagram of the layer structure of a display panel disclosed in the first embodiment of the present application. Figure 2 is Figure 1 a schematic diagram of the position alignment between the light-shielding stretching layer and the light-emitting unit when the display panel shown is stretched. As Figure 1 and Figure 2As shown in the figure, the display panel 100 provided by the embodiment of the present application includes a substrate 110, a light-emitting unit layer 120, a pixel definition layer 130, a packaging layer 140, and a filter stretching composite layer 150. Among them, the light-emitting unit layer 120 is disposed on the substrate 110, and the light-emitting unit layer 120 includes a plurality of light-emitting units 121, and the plurality of light-emitting units 121 are arranged in an array on the substrate 110. The pixel definition layer 130 is disposed on the substrate 110, and adjacent two light-emitting units 121 are separated by the pixel definition layer 130. Specifically, the pixel definition layer 130 and the light-emitting unit 121 are disposed on the same layer, and the pixel definition layer 130 is provided with a plurality of pixel openings 131 arranged at intervals, and the plurality of light-emitting units 121 are respectively located in the pixel openings 131 in one-to-one correspondence. The packaging layer 140 is disposed on one side of the plurality of light-emitting units 121 and the pixel definition layer 130 facing away from the substrate 110.

[0033] The filter stretching composite layer 150 is disposed on one side of the packaging layer 140 facing away from the pixel definition layer 130. The filter stretching composite layer 150 includes a plurality of color conversion portions 151 and a plurality of light-shielding stretching portions 153. The plurality of color conversion portions 151 are arranged in one-to-one correspondence with the plurality of light-emitting units 121. That is, the orthographic projection of the light-emitting unit 121 on the substrate 110 is within the range of the orthographic projection of the color conversion portion 151 on the substrate 110. The plurality of light-shielding stretching portions 153 are respectively disposed between adjacent color conversion portions 151, that is, one light-shielding stretching portion 153 is disposed between adjacent two color conversion portions 151. The light-shielding stretching portion 153 is used for stretching when the display panel 100 is deformed, so that the positions between the corresponding color conversion portion 151 and the light-emitting unit 121 are kept aligned.

[0034] It can be understood that currently in the market, the requirements for the deformation performance of display products such as stretching or bending are getting higher and higher. When the display panel is stretched, the light-emitting unit layer or other film layer structures will have corresponding displacements due to the difference in elastic coefficients during stretching. At the same time, the displacement magnitudes between different film layers may be different, which will cause misalignment of the functional structures in the layer positions in the stretched display panel, resulting in a decrease in the light intensity of the stretched display panel and various degrees of display abnormalities. The present application is directed to a display panel 100 using a Pol-less technology. By canceling the polarizer in the display panel and using a color filter to replace the polarizer, the loss of light is lower, the brightness is higher, and a better display effect is achieved. Among them, the color conversion part 151 and the light-shielding stretching part 153 form a COE structure. Therefore, by setting the COE structure to replace the polarizer, the reflection of the display panel can be reduced. In addition, the thickness of the COE structure can usually be less than the thickness of the polarizer, so that the total thickness of the display panel can be reduced, making the display panel more conducive to the application of foldable and rollable display products, and also conducive to improving the light transmittance of the display panel and reducing the power consumption of the display panel. And because the thickness of the display panel is reduced, when the display panel is applied to a 3D display product, it is also conducive to reducing the bonding difficulty between the display panel and other components in the 3D display product.

[0035] In an exemplary embodiment, the filter stretching composite layer 150 is configured to reduce the reflection of external light and replace the polarizer, which can effectively improve the transmittance and color saturation of the display panel and enhance the anti-bending property.

[0036] For convenience of description, the width direction of the display panel 100 can be defined as the X-axis direction, the length direction of the display panel 100 can be defined as the Y-axis direction, and the height direction of the display panel 100 (i.e., the stacking direction from the substrate 110 to the filter stretching composite layer 150) can be defined as the Z-axis direction. Among them, the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other in pairs. Among them, the X-axis direction can also be the first direction, the Y-axis direction can also be the second direction, and the Z-axis direction can also be the third direction. It can be understood that according to the product design requirements, the length direction of the display panel 100 can also be defined as the X-axis direction, and the width direction of the display panel 100 can be defined as the Y-axis direction. The present application does not make specific limitations on this.

[0037] In an embodiment of the present application, a plurality of the light-emitting units 121 are arranged in an array on the substrate 110, the pixel definition layer 130 is disposed on the substrate 110, and adjacent two of the light-emitting units 121 are separated by the pixel definition layer 130, and the encapsulation layer 140 is disposed on the plurality of light-emitting units 121 and the pixel definition layer 130. A plurality of the color conversion portions 151 and a plurality of the light-shielding stretching portions 153 are disposed on a side of the encapsulation layer 140 facing away from the pixel definition layer 130. Among them, positions of the plurality of color conversion portions 151 and positions of the plurality of light-emitting units 121 are arranged in one-to-one correspondence in the Z-axis direction, and one of the light-shielding stretching portions 153 is disposed between adjacent two of the color conversion portions 151. As Figure 2 shown, when the display panel 100 is stretched and deformed in the X-axis direction, the light-shielding stretching portion 153 is also stretched along the X-axis direction accordingly, and a distance between adjacent color conversion portions 151 becomes larger. Then, the color conversion portion 151 and the light-emitting unit 121 corresponding to a position before the display panel 100 is stretched still maintain relative alignment of positions at this time. That is to say, when the display panel 100 is stretched, the color conversion portion 151 and the light-emitting unit 121 always maintain relative alignment of positions in the Z-axis direction, that is, a positive projection of the light-emitting unit 121 on the substrate 110 is always located within a range of a positive projection of the color conversion portion 151 on the substrate 110.

[0038] In an embodiment of the present application, a length of the color conversion portion 151 in the X-axis direction is 1 to 2 μm larger than a length of the light-emitting unit 121 in the X-axis direction. For example, 1 μm, 1.2 μm, 1.5 μm, 1.8 μm, 2 μm, or other values, and the present application does not make specific limitations thereto. That is to say, a positive projection of the light-emitting unit 121 on the substrate 110 is located inside a positive projection of the color conversion portion 151 on the substrate 110, and boundaries of the positive projections do not overlap.

[0039] It can be understood that during the stretching process of the display panel 100, since the light-shielding stretching portion 153 has relatively large stretching elasticity, the color conversion portion 151 can be separately fixed by using a rigid substrate or other fixed encapsulation technologies. Then, deformation of the entire light-filtering stretching composite layer 150 is provided by the light-shielding stretching portion 153. At this time, it can be ensured that when the light-filtering stretching composite layer 150 is subjected to a stretching force, the color conversion portion 151 is not deformed due to a tensile force, avoiding a problem that in the prior art, when elasticity of a black matrix (BM) is small, a color resistor is still stretched and deformed. Therefore, when the display panel 100 of the present application is stretched, a relative position between the color conversion portion 151 and the light-emitting unit 121 always remains fixed and aligned.

[0040] In some specific embodiments, multiple signal lines may also be provided on the substrate 110. The multiple signal lines include multiple gate lines, multiple data lines, multiple initialization signal lines, multiple power supply lines, etc. For example, in one row of sub-pixels, a pixel driving circuit is connected to one gate line; in one column of sub-pixels, a pixel driving circuit is connected to one data line, one initialization signal line, and one power supply signal line. In this way, corresponding signals can be input to the pixel driving circuit through these signal lines to control the pixel driving circuit to drive the light-emitting device to emit light. The specific structure and working principle may be the same as those in the prior art and will not be elaborated here.

[0041] In the embodiment of the present application, the light-emitting unit 121 may be an organic light-emitting diode. The number of the light-emitting units 121 is the same as the number of pixel apertures and they are in one-to-one correspondence. Among them, the light-emitting unit 121 may include multiple types, and the light-emitting colors of the light-emitting layers of different types of light-emitting units 121 are different. For example, in this embodiment, the light-emitting unit 121 includes multiple red light-emitting units, multiple green light-emitting units, and multiple blue light-emitting units, and the red light-emitting units, the green light-emitting units, and the blue light-emitting units are arranged in an array. The display panel 100 in this embodiment is an OLED display panel with RGB light-emitting units as the light source. Of course, the light-emitting unit 121 in the present application may also be a white light-emitting unit, forming an OLED display panel with white light as the light source.

[0042] The color conversion part 151 may include a red light filter part, a green light filter part, and a blue light filter part. The red light filter part is a color film that allows red light to pass through, the green light filter part is a color film that allows green light to pass through, and the blue light filter part is a color film that allows blue light to pass through. When the light-emitting unit 121 of the display panel 100 is an RGB light-emitting unit and when the display panel 100 is stretched, the red light filter part is arranged corresponding to the red light-emitting unit, the green light filter part is arranged corresponding to the green light-emitting unit, and the blue light filter part is arranged corresponding to the blue light-emitting unit. When the display panel 100 is a white light-emitting unit, the red light filter part, the green light filter part, and the blue light filter part are arranged in an array.

[0043] In an exemplary embodiment, each of the light-emitting units 121 includes a top electrode, a light-emitting layer, and a bottom electrode. The bottom electrode, the light-emitting layer, and the top electrode are sequentially stacked on the substrate 110, and the bottom electrode is disposed under the pixel definition layer 130. The bottom electrode generally uses a metal electrode as the anode of the light-emitting unit 121. Of course, there are also composite electrodes with a stack of a transparent conductive layer and a metal electrode as the anode. The top electrode generally uses a transparent conductive layer as the cathode of the light-emitting unit 121. Since the bottom electrode has high reflectivity, under a certain voltage drive, electrons and holes move from the cathode and the anode to the light-emitting layer respectively, and visible light is emitted after recombination. Therefore, the light-emitting unit 121 generally emits light in one direction. For example, the bottom-emitting light-emitting unit 121. In addition, there is also a top-emitting light-emitting unit 121, which exchanges the use of the anode and cathode materials to form light emitted from top to bottom.

[0044] In an embodiment of the present application, the light-shielding stretching portion 153 may be formed by a composite of a black matrix (BM) material and a metal-organic frameworks (MOF) material.

[0045] It should be noted that in the embodiments of the present application, the MOF material is a crystalline porous material with a periodic network structure formed by the self-assembly connection of inorganic metal centers (metal ions or metal clusters) and bridging organic ligands. The MOF material has many unique properties, including high porosity, low density, large specific surface area, regular pores, adjustable pore size, and topological diversity. The MOF material is an organic-inorganic hybrid material, also known as a coordination polymer, which combines the rigidity of inorganic materials and the flexibility of organic materials. Through the method of confined interface synthesis and controlled by "reaction-diffusion", a wrinkled MOF film containing various patterns was obtained, unlocking the stretchable performance of the MOF film. Specifically, a polymer coating layer was added to the surface of zinc oxide deposited by atomic layer deposition (ALD), thus constructing a confined reaction space. In this space, the reaction reagents for synthesizing MOF diffuse from top to bottom, and the alkaline hydrolysis products released from the surface of zinc oxide diffuse from bottom to top, thus forming a set of chemically traveling waves moving towards each other. By mathematical modeling and numerical simulation and by regulating the "reaction-diffusion" conditions, unstable states of waves with various morphologies can be obtained, that is, patterns are generated. Further, by changing the concentration of the reaction reagents and the thickness of the polymer coating layer, various types of patterns are prepared, and a wrinkled MOF film with adjustable morphology is obtained. These patterns include, but are not limited to, various pattern types such as labyrinth-like stripes, dots, rings, etc. It can be understood that the introduction of the wrinkled structure not only greatly increases the effective surface area of the MOF film, but also endows the film with excellent flexibility, enabling it to withstand a strain of up to 53.2% without being damaged. The excellent mechanical properties of the wrinkled MOF film enable the MOF material to be easily transferred between different substrates like a "sticker". For example, when it is transferred to various substrates such as plexiglass, porous ceramics, and metal electrodes, the structure and properties of the wrinkled MOF film can be well retained. Therefore, the light-shielding stretching part 153 can be formed by physical compounding / physical bonding of a black matrix material and a metal-organic framework material. The formed composite film layer has a wrinkled structure, thus having good stretching characteristics, and the light-shielding stretching part 153 formed after compounding is opaque before and after stretching.

[0046] In the embodiment of the present application, based on the physical and chemical properties of the above-mentioned MOF material, the preparation method of the light-shielding stretching portion 153 includes: first depositing patterned zinc oxide (ZnO) on the COE substrate PI or other flexible materials; reacting on the surface of zinc oxide to prepare a COF corrugated film; coating the surface of the COF corrugated film with BM material, so as to form the above-mentioned light-shielding stretching portion 153. It can be understood that since the COF corrugated film itself is a metal / organic polymer material, the BM material can be coated on the surface of the COF corrugated film by inkjet printing or photolithography. Since the surface of the COF corrugated film has a large number of corrugated structures, the BM solvent can fill the grooves in the area, and the corrugated structure can be stretched and deformed during stretching, which can improve the service life.

[0047] In another embodiment of the present application, based on the physical and chemical properties of the above-mentioned MOF material, the preparation method of the light-shielding stretching portion 153 includes: preparing the required MOF corrugated film, transferring the prepared MOF corrugated film to a preset position and fixing it, and coating the BM material on the fixed MOF corrugated film, so as to form the above-mentioned light-shielding stretching portion 153. It can be understood that since the COF corrugated film itself is a metal / organic polymer material, the MOF corrugated film can be fixed by electrostatic adsorption or colloid adhesion with the substrate, and the BM material is coated on the surface of the COF corrugated film by inkjet printing or photolithography. Since the surface of the COF corrugated film has a large number of corrugated structures, the BM solvent can fill the grooves in the area, and the corrugated structure can be stretched and deformed during stretching, which can improve the service life.

[0048] In the embodiment of the present application, the display panel 100 is provided with a light-shielding stretching portion 153 between adjacent color conversion portions 151. When the display panel 100 is stretched, the displacement and deformation of the color conversion portion 151 during stretching can be reduced or avoided, and the color conversion portion 151 and the corresponding light-emitting unit 121 can be ensured to always maintain position alignment, which can prevent the color conversion portion 151 and the corresponding light-emitting unit 121 from being misaligned when the display panel 100 is stretched, thereby improving the display effect of the display panel 100.

[0049] In another embodiment of the present application, the color conversion unit 151 may be formed by combining a color resist material and a MOF material.

[0050] It can be understood that during the stretching process of the display panel 100, since the MOF material as a whole has a large tensile elasticity, the color conversion part 151 can be separately fixed using a flexible substrate material, so that the color conversion part 151 also has a certain tensile property (it can be understood that the tensile property of the color conversion part 151 is much smaller than that of the light-shielding stretching part 153). Then, the deformation of the entire filter light-stretching composite layer 150 is still mainly provided by the light-shielding stretching part 153. At this time, it can be ensured that when the filter light-stretching composite layer 150 is subjected to a tensile force, the color conversion part 151 is subjected to a tensile force and undergoes slight deformation, avoiding the problem in the prior art that when the elasticity of the black matrix (BM) is small, the color resistor is still stretched and undergoes large deformation. Therefore, when the display panel 100 of the present application is stretched, the color conversion part 151 will undergo slight deformation, and the area of the color resistor increases, that is, the overall area of the color resistor above the light-emitting unit layer 120 increases. Thus, not only can the relative position between the color conversion part 151 and the light-emitting unit 121 be always kept fixed and aligned, but also the light output and light intensity of the display panel 100 can be increased.

[0051] In an embodiment of the present application, the color conversion part 151 can be formed by physically compounding / physically bonding a color resistor material and a metal-organic framework material. The formed composite filter film layer has a certain tensile property, and the color conversion part 151 formed after the compounding retains the properties of the color resistor layer.

[0052] In an embodiment of the present application, based on the physical and chemical properties of the above MOF material, the preparation method of the color conversion part 151 includes: first depositing patterned zinc oxide (ZnO) on a COE substrate PI or other flexible materials; preparing a COF wrinkled film on the surface of the zinc oxide; and coating a color resistor material on the surface of the COF wrinkled film, so that the color conversion part 151 can be formed. It can be understood that since the COF wrinkled film itself is a metal / organic polymer material, the color resistor material can be coated on the surface of the COF wrinkled film by inkjet printing or photolithography. Since the surface of the COF wrinkled film has a large number of wrinkled structures, the color resistor solvent can fill the grooves in this area, and slight tensile deformation can occur along with the wrinkled structures during stretching, which can improve the service life.

[0053] In another embodiment of the present application, based on the physical and chemical properties of the above-mentioned MOF material, the preparation method of the color conversion unit 151 includes: preparing the required MOF corrugated film, transferring the prepared MOF corrugated film to a preset position and fixing it, coating the color resist material on the fixed MOF corrugated film, so as to form the above-mentioned color conversion unit 151. It can be understood that since the COF corrugated film itself is a metal / organic polymer material, the MOF corrugated film can be fixed by electrostatic adsorption or colloidal adhesion with the substrate, and the color resist material is coated on the surface of the COF corrugated film by inkjet printing or photolithography. Since the surface of the COF corrugated film has a large number of corrugated structures, the color resist solvent can fill the grooves in the area, and the corrugated structure can be slightly stretched and deformed during stretching, which can improve the service life.

[0054] It should be noted that the "patterning process" mentioned in this application includes processes such as coating photoresist, mask exposure, development, etching, and stripping photoresist for metal materials, inorganic materials, or transparent conductive materials, and includes processes such as coating organic materials, mask exposure, and development for organic materials. Deposition can be any one or more of sputtering, evaporation, and chemical vapor deposition, coating can be any one or more of spraying, spin coating, and inkjet printing, and etching can be any one or more of dry etching and wet etching, and this application does not make specific restrictions. "Thin film" refers to a layer of thin film made by deposition, coating, or other processes on a substrate of a certain material. If the "thin film" does not require a patterning process during the entire production process, the "thin film" can also be called a "layer". If the "thin film" requires a patterning process during the entire production process, it is called a "thin film" before the patterning process and a "layer" after the patterning process. "A and B are arranged in the same layer" mentioned in this disclosure means that A and B are formed simultaneously through the same patterning process.

[0055] Considering that most of the film layers in the display panel 100 have a certain degree of ductility, such as metal layers, organic film layers, etc., but the ductility of color resistance, light-emitting units, etc. is poor, and it is easy to cause the problem of breaking during the stretching process. The display panel 100 of this embodiment is provided with a light-shielding stretching portion 153 between adjacent color conversion portions 151. When the display panel 100 is stretched, the displacement and deformation of the color conversion portion 151 during stretching can be reduced or avoided. On the one hand, it is to prevent the color resistance from being generally an inorganic material, which has poor ductility and is prone to breaking. On the other hand, in order to prevent the cross-color between different colors of light, the light-shielding stretching portion 153 is provided between adjacent color conversion portions 151, so that a black matrix (BM) is provided between different color resistances to absorb the colored light at the edge of the color resistance and the natural light in the non-pixel opening area in the environment, and these color filters of different colors are separated from each other by the black matrix.

[0056] In an embodiment of the present application, the orthographic projection of the color conversion part 151 on the substrate 110 and the orthographic projection of the corresponding light-emitting unit 121 on the substrate 110 are always aligned when the display panel 100 is stretched. The meaning of "always aligned" in this embodiment is that: when the display panel 100 is stretched and displaying, the position of the light-emitting unit 121 is always set corresponding to the position of the color conversion part 151, and when light is emitted, the light emitted by the light-emitting unit 121 exactly emits from the corresponding color conversion part 151.

[0057] In an embodiment of the present application, the display panel 100 further includes a functional layer (FL) 160, and the functional layer 160 is disposed on a side of the filter stretching composite layer 150 facing away from the encapsulation layer 140. In an exemplary embodiment, the functional layer may be a touch structure layer (TSP), which has light transmissivity. The touch structure layer may include a touch control electrode layer, or may include a touch control electrode layer and a touch control insulating layer, etc., which are not limited in the present application.

[0058] In summary, the display panel 100 provided by the embodiment of the present application includes a substrate substrate 110, a light-emitting unit layer 120, a pixel definition layer 130, a packaging layer 140, and a filter stretching composite layer 150. Among them, the light-emitting unit layer 120 is disposed on the substrate substrate 110, and the light-emitting unit layer 120 includes a plurality of light-emitting units 121, and the plurality of light-emitting units 121 are arranged in an array on the substrate substrate 110. The pixel definition layer 130 is disposed on the substrate substrate 110, and adjacent two light-emitting units 121 are separated by the pixel definition layer 130. The packaging layer 140 is disposed on a side of the plurality of light-emitting units 121 and the pixel definition layer 130 facing away from the substrate substrate 110. The filter stretching composite layer 150 is disposed on a side of the packaging layer 140 facing away from the pixel definition layer 130. The filter stretching composite layer 150 includes a plurality of color conversion portions 151 and a plurality of light-shielding stretching portions 153. The plurality of color conversion portions 151 are provided in one-to-one correspondence with the plurality of light-emitting units 121, and one light-shielding stretching portion 153 is disposed between adjacent two color conversion portions 151. The light-shielding stretching portion 153 is configured to stretch when the display panel 100 is deformed, so that the positions between the corresponding color conversion portion 151 and the light-emitting unit 121 are kept aligned. Therefore, by providing the light-shielding stretching portion 153 between adjacent color conversion portions 151, when the display panel 100 is stretched, the light-shielding stretching portion 153 can make the color conversion portion 151 and the light-emitting unit 121 always keep their positions aligned in the Z-axis direction, that is, the relative positions between the color conversion portion 151 and the light-emitting unit 121 always remain fixed and aligned, and the problem that the color conversion portion 151 and the corresponding light-emitting unit 121 are misaligned when the display panel 100 is stretched and deformed can be prevented. Thus, by using the light-shielding stretching portion 153, the display panel 100 of the present application can ensure that the relative positions between the color conversion portion 151 and the light-emitting unit 121 always remain fixed and aligned when the display panel 100 is stretched, can ensure the light intensity of the display panel 100, avoid abnormal display of the display panel 100, and further improve the display effect of the display panel 100 and enhance the quality of the display panel 100.
