Abstract
Description
Technical Field
[0001] This application belongs to the technical field of display devices, and particularly relates to a display module, an electronic device, and a method for manufacturing a display module. Background Art
[0002] In order to make the display module meet the requirements of being thinner, lower power consumption, bendable, etc., in the OLED (Organic Light-Emitting Diode) display screen industry, a de-polarizer technology has emerged, and a thinner color filter structure, that is, CF (Color Filter), is used to replace the polarizer, which will significantly reduce the thickness of the display module and improve the brightness.
[0003] This solution of replacing the polarizer with a color filter is called the COE (Color filter on encapsulation) solution, that is, the color filter is installed between the touch screen and the encapsulation layer of the display module. In addition, the color filter can also be installed between the touch screen and the cover plate. At the same time, in the COE solution, pixels of different colors are separated by a black matrix, and the black matrix can absorb light that does not need to enter the display module while avoiding crosstalk between pixels, so as to solve the problems of reflection and light transmission of the display module.
[0004] However, with the advent of the folding screen technology, the COE solution still makes the thickness of the display module relatively thick, which makes it difficult for the display module to be folded. Therefore, the display module involved in the related technology has the problem that it is difficult to achieve the folding function. Summary of the Invention
[0005] The purpose of the embodiments of this application is to provide a display module, an electronic device, and a method for manufacturing a display module, which can solve the problem that the display module involved in the related technology is difficult to achieve the folding function.
[0006] In a first aspect, the embodiments of this application provide a display module, including an organic light-emitting layer and a plurality of functional layers stacked in the thickness direction of the display module. The organic light-emitting layer includes a plurality of spaced-apart light-emitting pixels. The functional layer has a plurality of quantum dot photoresist layers and quantum dot light-shielding layers. The quantum dot light-shielding layer is disposed in the gap between adjacent quantum dot photoresist layers, and each quantum dot photoresist layer is correspondingly disposed with each light-emitting pixel.
[0007] In a second aspect, the embodiments of this application provide an electronic device, including the display module described above.
[0008] In a third aspect, the embodiments of this application provide a method for manufacturing a display module, which is applied to the display module described above. The method includes:
[0009] Irradiate a plurality of first target areas of the functional layer with laser light so as to form a quantum dot photoresist layer within the first target areas;
[0010] Irradiate a second target area of the functional layer with laser light so as to form a quantum dot light-shielding layer within the second target area, where: the second target area is disposed between each of the first target areas.
[0011] In the embodiments of the present application, by irradiating the interior of the functional layer with laser light, a quantum dot photoresist layer and a quantum dot light-shielding layer are formed inside the functional layer. A plurality of quantum dot photoresist layers and a plurality of spaced-apart light-emitting pixels of the organic light-emitting layer are correspondingly arranged, so that the quantum dot photoresist layer and the quantum dot light-shielding layer can filter and adjust the light entering the display module from the outside of the display module, that is, solve the problem of light reflection of the display module. At the same time, since the quantum dot photoresist layer is formed inside the functional layer, therefore, compared with the conventional scheme of laminating a functional layer and a quantum dot photoresist layer, the present application can reduce the thickness of the display module to a certain extent, which makes it easier for the display module to be folded. Therefore, the present application can solve the problem that the display module in the related art is difficult to achieve the folding function. Description of the Drawings

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.
[0025] Next, in conjunction with the accompanying drawings, the display module disclosed in the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.
[0026] Please refer to Figures 1 - 12 , the present application discloses a display module, and the disclosed display module includes an organic light-emitting layer 100 and a functional layer 200.
[0027] The organic light-emitting layer 100 is the light source of the display module. Specifically, the organic light-emitting layer 100 includes a plurality of spaced-apart light-emitting pixels 110. The colors of the light emitted by the plurality of light-emitting pixels 110 are generally RGB, that is, the three primary colors. In addition, the display module further includes structures such as thin-film transistors, cathodes, anodes, etc. for driving the organic light-emitting layer 100 to emit light.
[0028] There are multiple functional layers 200, and the multiple functional layers 200 are stacked in sequence in the thickness direction of the display module. The multiple functional layers 200 are components of the display module for realizing display functions, touch functions, protection functions, etc. At least one functional layer 200 has multiple quantum dot photoresist layers 300 and quantum dot light-shielding layers 400. Each quantum dot photoresist layer 300 is correspondingly arranged with each light-emitting pixel 110, so that the quantum dot photoresist layer 300 performs selective light transmission on the light emitted by the light-emitting pixel 110. At the same time, the quantum dot photoresist layer 300 also has the effect of reducing the reflection of external ambient light, that is, the quantum dot photoresist layer 300 has the function of filtering and adjusting the light entering from the external environment, that is, the quantum dot photoresist layer 300 acts as a filter, so that users can clearly see the picture displayed by the display module even in the sun.
[0029] The quantum dot light-shielding layer 400 has the function of absorbing the reflection of external ambient light. That is, when external light is incident on the display module and irradiates on the quantum dot light-shielding layer 400, all the light will be absorbed by the quantum dot light-shielding layer 400. At the same time, the light emitted by the light-emitting pixel 110 will also be absorbed when it irradiates on the quantum dot light-shielding layer 400. The quantum dot light-shielding layer 400 is arranged in the gap between adjacent quantum dot photoresist layers 300 to avoid the phenomenon of color crosstalk between adjacent quantum dot photoresist layers 300. Optionally, the quantum dot light-shielding layer 400 can be a black matrix.
[0030] Optionally, the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 in the functional layer 200 can be formed by laser excitation, and the laser can be emitted by a laser device 500.
[0031] In the embodiment of the present application, by irradiating a laser into the functional layer 200, a quantum dot photoresist layer 300 and a quantum dot light-shielding layer 400 are formed inside the functional layer 200. The multiple quantum dot photoresist layers 300 are correspondingly arranged with the multiple spaced-apart light-emitting pixels 110 of the organic light-emitting layer 100, so that the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 can filter and adjust the light entering the display module from the outside of the display module, that is, solve the problem of light reflection of the display module. At the same time, since the quantum dot photoresist layer 300 is formed inside the functional layer 200, therefore, compared with the conventional scheme of stacking the functional layer 200 and the quantum dot photoresist layer 300, the present application can reduce the thickness of the display module to a certain extent, which makes it easier for the display module to be folded. Therefore, the present application can solve the problem that the display module involved in the related art is difficult to realize the folding function.
[0032] Optionally, the multiple functional layers 200 include a touch layer 210, a cover plate 220, an optical adhesive layer 230, and a packaging layer 240. The packaging layer 240, the touch layer 210, the optical adhesive layer 230, and the cover plate 220 are stacked in sequence, and the cover plate 220 is generally disposed on the outermost layer of the display module to protect the touch layer 210. At the same time, the cover plate 220 has functions such as shock resistance, scratch resistance, oil resistance, fingerprint prevention, and enhanced light transmittance. The optical adhesive layer 230 is generally a cemented transparent optical element, which is used to connect the cover plate 220 and the touch layer 210. The touch layer 210 is used to implement the touch function of the electronic device, and the packaging layer 240 is used to prevent moisture and oxygen from penetrating into the interior of the display module.
[0033] Among the cover plate 220, the touch layer 210, the packaging layer 240, and the optical adhesive layer 230, at least one has a quantum dot photoresist layer 300 and a quantum dot light-shielding layer 400. Specifically, among the interior of the cover plate 220, the interior of the touch layer 210, the interior of the packaging layer 240, and the interior of the optical adhesive layer 230, at least one has a quantum dot photoresist layer 300 and a quantum dot light-shielding layer 400. The cover plate 220, the touch layer 210, the packaging layer 240, and the optical adhesive layer 230 can be used to protect the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400.
[0034] In one embodiment, the functional layer 200 includes a matrix and nanocrystals 250 doped in the matrix. The matrix is generally a glass matrix. The nanocrystals 250 can precipitate and form a quantum dot photoresist layer 300 and a quantum dot light-shielding layer 400 under high-temperature heating. The matrix can completely coat the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 and isolate them from the external environment. This can not only effectively improve the stability and enhance the water and oxygen resistance of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400, but also effectively avoid the leakage of heavy metal elements such as lead and cadmium, which greatly reduces the impact of metal elements on the environment and human health.
[0035] In another embodiment, the nanocrystals 250 can precipitate and form a quantum dot photoresist layer 300 and a quantum dot light-shielding layer 400 under the action of a laser. Specifically, by irradiating the nanocrystals 250 with an ultrafast laser, the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 are directly induced to generate inside the matrix. This method of generating the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 by laser induction does not require multiple photolithography processes. Therefore, this setting method can improve the production yield and reduce the cost.
[0036] Optionally, other materials can also be used to generate the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400, such as polymers and the like.
[0037] Optionally, the functional layer 200 has a first surface 260 and a second surface 270 facing away from each other in the thickness direction. At least one of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 can be located on the first surface 260 or the second surface 270, that is, at least one of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 is disposed close to the outer surface of the functional layer 200. At this time, since at least one of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 is close to the external environment, at least one of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 is easily oxidized by water and oxygen in the environment, which easily affects the display effect of the display module.
[0038] To avoid the above influence, in another embodiment, at least one of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 is located between the first surface 260 and the second surface 270, that is, at least one of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 is disposed away from the outer surface of the functional layer 200, and thus away from the external environment. At this time, oxidation of at least one of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 by water and oxygen in the environment can be avoided, that is, the protection effect of the functional layer 200 on at least one of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 is better. At the same time, this setting method can effectively improve the optical performance of the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400, and thus improve the display effect of the display module.
[0039] Optionally, the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 can be disposed on different layers. At this time, in the thickness direction of the functional layer 200, the space occupied by the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 is relatively large, and thus the thickness of the functional layer 200 is increased, and thus the thickness of the display module is increased, which is not conducive to the realization of the folding function of the display module.
[0040] Therefore, in another embodiment, the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 are disposed on the same layer. At this time, the space of the functional layer 200 occupied by the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 in the thickness direction of the functional layer 200 is relatively small, and thus the thickness of the functional layer 200 is reduced, and thus the thickness of the display module is reduced, which is conducive to the realization of the folding function of the display module. At the same time, the quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 are disposed on the same layer, so that the quantum dot light-shielding layer 400 can better prevent crosstalk between adjacent quantum dot photoresist layers 300.
[0041] Optionally, the organic light-emitting layer 100 further includes a pixel spacer 120 disposed in the gap between adjacent light-emitting pixels 110. The pixel spacer 120 is used to prevent color mixing between adjacent light-emitting pixels 110. In the thickness direction, a part of the orthographic projection contour line of the pixel spacer 120 coincides with a part of the orthographic projection contour line of the quantum dot light-shielding layer 400, that is, a part of the pixel spacer 120 is disposed opposite to a part of the quantum dot light-shielding layer 400, and a part of the orthographic projection contour line of the light-emitting pixel 110 coincides with a part of the orthographic projection contour line of the quantum dot photoresist layer 300, that is, a part of the light-emitting pixel 110 is disposed opposite to a part of the quantum dot photoresist layer 300. At this time, only a part of the light emitted by the light-emitting pixel 110 can pass through the quantum dot photoresist layer 300, which results in a poor display effect of the display module.
[0042] Therefore, to ensure the display effect of the display module, in another embodiment, the entire orthographic projection contour line of the pixel spacer 120 coincides with the entire orthographic projection contour line of the quantum dot light-shielding layer 400, that is, the entire pixel spacer 120 is disposed opposite to the entire quantum dot light-shielding layer 400, and the entire orthographic projection contour line of the light-emitting pixel 110 coincides with the entire orthographic projection contour line of the quantum dot photoresist layer 300, that is, the entire light-emitting pixel 110 is disposed opposite to the entire quantum dot photoresist layer 300. At this time, all the light emitted by the light-emitting pixel 110 can pass through the quantum dot photoresist layer 300 disposed opposite thereto, so that the display module can display all this light, thereby improving the display effect of the display module.
[0043] Optionally, the plurality of light-emitting pixels 110 include a first light-emitting pixel 111, a second light-emitting pixel 112, and a third light-emitting pixel 113. The colors of the light emitted by the first light-emitting pixel 111, the second light-emitting pixel 112, and the third light-emitting pixel 113 can be respectively one of the three primary colors. The plurality of quantum dot photoresist layers 300 include a first photoresist layer 310, a second photoresist layer 320, and a third photoresist layer 330. The colors of the first photoresist layer 310, the second photoresist layer 320, and the third photoresist layer 330 can also be respectively one of the three primary colors.
[0044] The first light-emitting pixel 111 and the first photoresist layer 310 are arranged in the thickness direction, and the color of the light emitted by the first light-emitting pixel 111 may be different from the color of the first photoresist layer 310; the second light-emitting pixel 112 and the second photoresist layer 320 are arranged in the thickness direction, and the color of the light emitted by the second light-emitting pixel 112 may be different from the color of the second photoresist layer 320; the third light-emitting pixel 113 and the third photoresist layer 330 are arranged in the thickness direction, and the color of the light emitted by the third light-emitting pixel 113 may be different from the color of the third photoresist layer 330. However, with this setting method, only a small part of the light emitted by the first light-emitting pixel 111, the second light-emitting pixel 112, and the third light-emitting pixel 113 may pass through the corresponding photoresist layers, which results in a poor color rendering of the display module.
[0045] In order to improve the color rendering of the display module, in another embodiment, the first light-emitting pixel 111 and the first photoresist layer 310 are arranged in the thickness direction, and the color of the light emitted by the first light-emitting pixel 111 is the same as the color of the first photoresist layer 310; the second light-emitting pixel 112 and the second photoresist layer 320 are arranged in the thickness direction, and the color of the light emitted by the second light-emitting pixel 112 is the same as the color of the second photoresist layer 320; the third light-emitting pixel 113 and the third photoresist layer 330 are arranged in the thickness direction, and the color of the light emitted by the third light-emitting pixel 113 is the same as the color of the third photoresist layer 330. With this setting method, most of the light emitted by the first light-emitting pixel 111, the second light-emitting pixel 112, and the third light-emitting pixel 113 can pass through the corresponding first photoresist layer 310, second photoresist layer 320, and third photoresist layer 330, thereby improving the color rendering of the display module.
[0046] Optionally, the present application also discloses an electronic device, and the disclosed electronic device includes the display module described above.
[0047] As Figure 12 shown, the embodiment of the present application also discloses a method for manufacturing a display module. The method for manufacturing the display module is applied to the display module described in any of the above embodiments, and the method includes:
[0048] S100. Irradiate a plurality of first target areas of the functional layer 200 with laser light to form a quantum dot photoresist layer 300 in the first target areas.
[0049] Specifically, the functional layer 200 is filled with a matrix, and nanocrystals are provided inside the matrix. The nanocrystals are the nanocrystals 250 described above. The area provided with the nanocrystals 250 is divided into a plurality of first target areas, and a laser device 500 is used to irradiate the plurality of first target areas with laser light to form a quantum dot photoresist layer 300 in each first target area. Optionally, the laser device 500 can irradiate the plurality of first target areas sequentially or simultaneously.
[0050] S200. Irradiate a laser onto a second target area of the functional layer 200 to form a quantum dot light-shielding layer 400 in the second target area, where: the second target area is disposed between each of the first target areas.
[0051] Specifically, the area where the nanocrystals 250 are disposed is further divided into second target areas, where: the second target areas are disposed between each of the first target areas, that is, each of the first target areas is separated by the second target areas. Laser irradiation is performed on the second target areas through a laser device 500 to form a quantum dot light-shielding layer 400 in each of the second target areas, so that the quantum dot light-shielding layer 400 is disposed in the gap between adjacent quantum dot photoresist layers 300. Optionally, the laser device 500 can irradiate multiple positions of the second target area in sequence, or can irradiate multiple positions of the second target area simultaneously.
[0052] The method for manufacturing a display module disclosed in the embodiments of the present application forms a quantum dot photoresist layer 300 and a quantum dot light-shielding layer 400 inside the functional layer 200 by irradiating a laser onto multiple first target areas and second target areas in the functional layer 200. The quantum dot photoresist layer 300 and the quantum dot light-shielding layer 400 can filter and adjust the light entering the display module from the outside of the display module, that is, solve the problem of light reflection of the display module. At the same time, since the quantum dot photoresist layer 300 is formed inside the functional layer 200, therefore, compared with the conventional scheme of stacking the functional layer 200 and the quantum dot photoresist layer 300, the present application can reduce the thickness of the display module to a certain extent, which makes it easier for the display module to be folded.
[0053] Optionally, the first target area includes a first sub-area, a second sub-area, and a third sub-area. The above step S100 specifically includes:
[0054] S110. Irradiate lasers with different operating parameters onto the first sub-area, the second sub-area, and the third sub-area respectively, so as to form a first photoresist layer 310 with a first target wavelength in the first sub-area, a second photoresist layer 320 with a second target wavelength in the second sub-area, and a third photoresist layer 330 with a third target wavelength in the third sub-area.
[0055] Optionally, the operating parameters of the laser may include laser exposure time, laser energy, etc. By irradiating the first sub-region, the second sub-region, and the third sub-region inside the substrate with lasers having different operating parameters, quantum dot photoresist layers 300 with different wavelengths are induced to be generated, that is, a first photoresist layer 310 with a first target wavelength is formed in the first sub-region, a second photoresist layer 320 with a second target wavelength is formed in the second sub-region, and a third photoresist layer 330 with a third target wavelength is formed in the third sub-region. Since the first photoresist layer 310, the second photoresist layer 320, and the third photoresist layer 330 have different wavelengths, the first photoresist layer 310, the second photoresist layer 320, and the third photoresist layer 330 can filter light of different colors.
[0056] Optionally, a quantum dot light-shielding layer 400 is disposed between the first photoresist layer 310, the second photoresist layer 320, and the third photoresist layer 330. The quantum dot light-shielding layer 400 can prevent color crosstalk from occurring between the first photoresist layer 310, the second photoresist layer 320, and the third photoresist layer 330.
[0057] The electronic device in the embodiments of the present application may be a terminal or other devices other than the terminal. Exemplarily, the electronic device may be a mobile phone, a tablet computer, a notebook computer, a handheld computer, an in-vehicle electronic device, a Mobile Internet Device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. It may also be a server, a Network Attached Storage (NAS), a personal computer (PC), a television (TV), a teller machine, or a self-service machine, etc. The embodiments of the present application do not make specific limitations.
[0058] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
