Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and a display terminal. Background Technology

[0002] Micro-LED (Micro-Light Emitting Diode) and OLED (Organic Light Emitting Diode) display technologies are among the hottest trends in future display technologies. Compared to current Liquid Crystal Display (LCD) devices, Micro-LED and OLED displays offer advantages such as faster response times, wider color gamut, higher PPI, and lower energy consumption. However, they also face numerous technical challenges and are highly complex. For example, OLED technology suffers from low efficiency and short lifespan of red and green OLED materials, while Micro-LED technology faces similar issues with low production volume and luminous efficiency of red and green LEDs. For these reasons, color conversion display technology is becoming increasingly prevalent.

[0003] Color conversion display technology generally refers to the technology of displaying the three primary colors of red, green, and blue (RGB) by using a monochromatic light source in conjunction with the color conversion capability of quantum dots (QDs). Because blue has the shortest wavelength and the highest energy, it can excite the other two colors with the highest excitation efficiency, and color conversion display technology generally uses blue as the reference light source.

[0004] However, in related technologies, color conversion display technology generally uses pure black resin materials, resulting in a loss of brightness. Therefore, how to improve the contrast of the display panel without sacrificing the brightness of the light-emitting area has become an increasingly important technical challenge. Summary of the Invention

[0005] In view of this, this application proposes a display panel and display terminal that can switch the structural state of the photosensitive layer according to the light emitted by the multiple pixel units. When the corresponding pixel units do not emit light, they cross-link to form a three-dimensional network structure; when the corresponding pixel units emit light, they de-crosslink to form a linear chain structure. This makes the photosensitive layer corresponding to the display area with light source in the display panel transparent and highly transparent, thereby reducing the brightness loss of the display panel. Meanwhile, the photosensitive layer corresponding to the display area without light source in the display panel is black and opaque, making the black areas darker and the bright areas brighter, thereby improving the contrast of the display panel. This method is simple and efficient.

[0006] According to one aspect of this application, a display panel is provided, the display panel comprising: a back panel; a light-emitting layer comprising a plurality of pixel units arranged in an array, the light-emitting layer being located on the back panel; and a photosensitive layer located on the light-emitting layer, wherein: the photosensitive layer comprises a plurality of polymer chains, the plurality of polymer chains being cross-linked to each other to form a three-dimensional network structure when the corresponding pixel units are not emitting light; and the plurality of polymer chains being decross-linked to form a linear chain structure when the corresponding pixel units emit light.

[0007] Furthermore, the photosensitive layer comprises a resin material, and the plurality of polymer chains are located in the resin material, wherein: the polymers in the plurality of polymer chains include at least one of diazo groups, diazoquinone groups, and azide groups.

[0008] Furthermore, each of the pixel units includes at least one light-emitting component, which is used to emit blue light.

[0009] Furthermore, the display panel also includes a driving circuit layer located on the back panel, and the light-emitting layer is located on the driving circuit layer.

[0010] Furthermore, a non-light-emitting area is provided between each of the pixel units, and a light-shielding material is provided in the non-light-emitting area. The light-shielding material is located on the driving circuit layer, wherein the height of the light-shielding material is the same as the height of the pixel unit adjacent to the light-shielding material.

[0011] Furthermore, the light-emitting component includes a non-light-emitting side and a light-emitting side facing away from the driving circuit layer, wherein: the light-emitting component is provided with a light-blocking package, and the light-blocking package covers the non-light-emitting side of the light-emitting component.

[0012] Furthermore, when the plurality of pixel units emit light, the photosensitive layer includes a plurality of cross-linked regions and a plurality of uncross-linked regions. The plurality of cross-linked regions maintain a three-dimensional network structure, and the plurality of uncross-linked regions maintain a linear chain structure. The plurality of uncross-linked regions correspond to each of the pixel units.

[0013] Furthermore, the display panel also includes a quantum dot matrix layer disposed on the photosensitive layer, wherein: the quantum dot matrix layer includes a red quantum dot matrix and a green quantum dot matrix, the red quantum dot matrix includes a plurality of red quantum dots arranged in an array, and the green quantum dot matrix includes a plurality of green quantum dots arranged in an array.

[0014] Furthermore, the quantum dot lattice layer also includes a blue quantum dot lattice, which comprises multiple blue quantum dots arranged in an array.

[0015] According to another aspect of this application, a display terminal is provided, the display terminal including a terminal body and a display panel, the terminal body being connected to the display panel.

[0016] By placing the photosensitive layer on the light-emitting layer of the display panel, according to various aspects of this application, the structural state of the photosensitive layer can be switched according to the light emitted by the multiple pixel units. When the corresponding pixel units are not emitting light, they cross-link to form a three-dimensional network structure; when the corresponding pixel units are emitting light, they de-crosslink to form a linear chain structure. This makes the photosensitive layer corresponding to the display area with light source in the display panel transparent and highly transparent, thereby reducing the brightness loss of the display panel; while the photosensitive layer corresponding to the display area without light source in the display panel is black and opaque, making black areas darker and bright areas brighter, thereby improving the contrast of the display panel. This method is simple and efficient. Attached Figure Description

[0026] Figure 9 This diagram illustrates a light-blocking package according to an embodiment of this application. Detailed Implementation

[0027] This application mainly provides a display panel, the display panel comprising: a back panel; a light-emitting layer comprising a plurality of pixel units arranged in an array, the light-emitting layer being located on the back panel; and a photosensitive layer located on the light-emitting layer, wherein: the photosensitive layer comprises a plurality of polymer chains, the plurality of polymer chains cross-linking with each other when the corresponding pixel unit is not emitting light, forming a three-dimensional network structure; and the plurality of polymer chains uncross-linking when the corresponding pixel unit emits light, forming a linear chain structure.

[0028] By placing the photosensitive layer on the light-emitting layer of the display panel, this application can switch the structural state of the photosensitive layer according to the light emitted by the multiple pixel units. That is, when the corresponding pixel units do not emit light, they cross-link to form a three-dimensional network structure; when the corresponding pixel units emit light, they de-crosslink to form a linear chain structure. This makes the photosensitive layer corresponding to the display area with light source in the display panel transparent and highly transparent, thereby reducing the brightness loss of the display panel. Meanwhile, the photosensitive layer corresponding to the display area without light source in the display panel is black and opaque, making "black areas darker and bright areas brighter", thereby improving the contrast of the display panel.

[0029] Figure 1 A schematic diagram of the cross-linking structure of the display panel according to an embodiment of this application is shown.

[0030] like Figure 1 As shown, a driving circuit (i.e., array) layer 12 may be disposed on the back panel 11 of the display panel, and a plurality of pixel units arranged in an array are disposed on the driving circuit layer 12. Metal traces may be provided in the driving circuit layer 12 to electrically connect the back panel 11 to each of the pixel units, thereby driving each pixel unit to operate. The back panel may be a glass substrate, a PCB substrate, a BT resin substrate, or an aluminum substrate, etc. The driving circuit may employ AM TFT driving, AM Micro IC driving, or PM driving; this application does not limit the specific driving method.

[0031] The light-emitting layer may include multiple pixel units arranged in an array, and the light-emitting layer is located on the backplate. Each pixel unit may include at least one light-emitting component. The area where each pixel unit is located may be referred to as the light-emitting area. Each pixel unit includes at least one light-emitting component, which is used to emit blue light. The light-emitting component may be an LED, or a chip or other device. The light-emitting component may be bonded using methods such as surface mount, die bonding, or die bonding. For example, in... Figure 1 In this design, pixel unit 14 may include a first light-emitting component 141, a second light-emitting component 142, and a third light-emitting component 143. All light-emitting components may be blue LEDs for emitting blue light. The distance between the light-emitting components can be set as needed and is not limited in this application.

[0032] See Figure 1 Multiple non-light-emitting areas may be spaced apart on both sides of each pixel unit. Each non-light-emitting area may be filled with a black light-blocking material, such as black ink. The thickness of the black light-blocking material filling each non-light-emitting area may be the same. The black light-blocking material filling each non-light-emitting area can form a light-blocking layer 13.

[0033] Furthermore, such as Figure 1 As shown, a photosensitive layer 15 can be covered on each pixel unit, and the photosensitive layer 15 is located on the light-emitting layer. This photosensitive layer can have a three-dimensional network structure in a cross-linked state. The photosensitive layer 15 may include multiple cross-linked polymer chains. These polymer chains can sense external light and undergo a chemical reaction under the influence of external light, causing the originally cross-linked polymer chains to dissociate, forming a decrosslinked photosensitive layer. That is, the multiple polymer chains cross-link with each other when the corresponding pixel unit is not emitting light, forming a three-dimensional network structure; the multiple polymer chains decross-link with each other when the corresponding pixel unit emits light, forming a linear chain structure.

[0034] Figure 2 This diagram illustrates a cross-linked photosensitive layer according to an embodiment of this application.

[0035] See Figure 2 The photosensitive layer can be a resin film layer, which may include multiple polymer chains. The substrate of the photosensitive layer can be epoxy resin or other transparent resins. In the cross-linked photosensitive layer 15, the first polymer 151 and the second polymer 152 can form a stable three-dimensional network structure by means of forces such as hydrogen bonds and van der Waals forces. The polymer chains in the photosensitive layer 15 can extend along a first direction (i.e., transverse) or a second direction (i.e., longitudinal), and the polymer chains extending along the first direction and the polymer chains extending along the second direction can intersect perpendicularly.

[0036] The photosensitive layer comprises a resin material, and the plurality of polymer chains are located within the resin material. The polymers in the plurality of polymer chains include at least one of diazo groups, diazoquinone groups, and azido groups. That is, the polymers of the photosensitive layer may contain functional groups such as diazo groups, diazoquinone groups, or azido groups. The photosensitive layer may be made of a nitrogen-containing resin material, such as diazo-modified polystyrene (PS). It is understood that, in addition to diazo groups, diazoquinone groups, or azido groups, the photosensitive layer may also use other types of functional groups, as long as they exhibit the property of photolytic crosslinking. This application does not limit the specific material of the photosensitive layer.

[0037] Furthermore, when the plurality of pixel units emit light, the photosensitive layer includes a plurality of cross-linked regions and a plurality of uncross-linked regions. The plurality of cross-linked regions maintain a three-dimensional network structure, and the plurality of uncross-linked regions maintain a linear chain structure. The plurality of uncross-linked regions correspond to each of the pixel units.

[0038] Figure 3 A schematic diagram of the decrosslinking structure of the display panel according to an embodiment of this application is shown.

[0039] like Figure 3 As shown, the decrosslinking region 31 and the crosslinking region 32 can be adjacent to each other. Multiple decrosslinking regions and multiple crosslinking regions can be arranged alternately. The emitted light 211 from the first light-emitting component 141 can be captured by the human eye after passing through the decrosslinking region 31, thereby forming a display image. For example, the decrosslinking region can be located directly above the corresponding pixel unit, that is, corresponding to the pixel unit in a direction perpendicular to the light-emitting layer. It is understood that the size of the decrosslinking region depends on the light path emitted by the corresponding pixel unit, and this application does not limit the correspondence between the decrosslinking region and the pixel unit.

[0040] Figure 4 This diagram illustrates the decrosslinked photosensitive layer according to an embodiment of this application.

[0041] For example, see Figure 4 When the first polymer chain 41 and the second polymer chain 42 of the photosensitive layer are energized by the blue light emitted by the corresponding blue LED, the cross-linked functional groups begin to de-crosslink, and both the first polymer chain 41 and the second polymer chain 42 become linear molecular chains. Gaps exist between the different linear molecular chains after de-crosslinking, allowing light to pass through. Macroscopically, this manifests as a transparent state of the de-crosslinked photosensitive layer with high light transmittance.

[0042] Because this application introduces a photosensitive layer to replace the pure black material in related technologies, in the absence of light, the polymer chains of the photosensitive layer are in a tightly cross-linked state, and the photosensitive layer appears black and is opaque. Under light, the polymer chains of the photosensitive layer de-crosslink, becoming linear polymer chains, and the photosensitive layer becomes transparent with high light transmittance. Therefore, by utilizing the photosensitive properties of this photosensitive layer, the photosensitive layer corresponding to the display area with a light source in the display panel becomes transparent with high light transmittance, thereby reducing the brightness loss of the display panel; while the photosensitive layer corresponding to the display area without a light source in the display panel remains black and opaque, making "black areas darker and bright areas brighter," thereby improving the contrast of the display panel.

[0043] In practical applications, the display panel can be a backlit product or a direct-view product. The photosensitive layer can be applied to display panels of types such as Micro-LED, OLED, and LCD, and can be used to form three types of display panels: QD-Micro LED, QD-OLED, and QDCF-LCD, based on quantum dot (QD) technology. Of course, other types of display panels can also be formed based on the inventive concept of this application. The following description uses the above three types of display panels as examples.

[0044] Figure 5 A schematic diagram of the structure of a QD-Micro LED display panel according to an embodiment of this application is shown.

[0045] like Figure 5 As shown, the display panel may further include a first quantum dot matrix layer 51, which is disposed on the photosensitive layer 15. The first quantum dot matrix layer 51 may be located in a transparent substrate. Figure 5 In this design, the quantum dot array layer includes a red quantum dot array and a green quantum dot array. For example, the red quantum dot array includes multiple red quantum dots 511 arranged in an array, and the green quantum dot array includes multiple green quantum dots 512 arranged in an array. Adjacent red quantum dots 511 and green quantum dots 512 can form a quantum dot unit, corresponding to a pixel unit 14.

[0046] Among them, the red quantum dot 511 corresponds to the first blue LED 541, and the green quantum dot 512 corresponds to the second blue LED 542. Since the substrate is transparent, the blue light emitted by the third blue LED 543 can pass directly through the area corresponding to the first quantum dot array layer 51 directly above it.

[0047] It should be noted that the wavelength threshold for decrosslinking of the photosensitive decrosslinking film layer used in this application can be between 470 nm and 740 nm. For example, the wavelength threshold can be 470 nm, 520 nm, 740 nm, etc. When the wavelength of the light irradiating the photosensitive decrosslinking film layer is less than the decrosslinking wavelength threshold, the photosensitive decrosslinking film layer will undergo decrosslinking; when the wavelength of the light irradiating the photosensitive decrosslinking film layer is greater than or equal to the decrosslinking wavelength threshold, the photosensitive decrosslinking film layer will remain in a crosslinked state. Since the wavelength range of blue light is between 465 nm and 470 nm, this application uses blue light to decrosslink the photosensitive decrosslinking film layer, which can achieve a good decrosslinking effect.

[0048] In practical applications, using blue Micro LEDs combined with a quantum dot matrix layer can achieve full-color display. Furthermore, the fabrication process for blue Micro LEDs is mature and the cost is relatively low.

[0049] Figure 6 A schematic diagram of the structure of a QD-OLED display panel according to an embodiment of this application is shown.

[0050] like Figure 6 As shown, with Figure 5 The difference is, Figure 5 The blue LEDs in the image have all been replaced with blue OLED light-emitting devices, namely the first blue OLED light-emitting device 621, the second blue OLED light-emitting device 622, and the third blue OLED light-emitting device 623. The first blue OLED light-emitting device 621, the second blue OLED light-emitting device 622, and the third blue OLED light-emitting device 623 can be located in the same pixel unit 62.

[0051] exist Figure 6 The display panel may further include a second quantum dot matrix layer 61, which is disposed on the photosensitive layer 15. The second quantum dot matrix layer 61 may be located within a transparent substrate. Figure 6 In this design, the quantum dot array layer includes a red quantum dot array and a green quantum dot array. For example, the red quantum dot array includes multiple red quantum dots 611 arranged in an array, and the green quantum dot array includes multiple green quantum dots 612 arranged in an array. Adjacent red quantum dots 611 and green quantum dots 612 can form a quantum dot unit, corresponding to a pixel unit 62.

[0052] Figure 7 A schematic diagram of the structure of a QDCF-LCD display panel according to an embodiment of this application is shown.

[0053] like Figure 7 As shown, with Figure 5 Same, Figure 7 The pixel unit 72 may include a fourth blue LED 721, a fifth blue LED 722, and a sixth blue LED 723. Conversely, the display panel may also include a third quantum dot matrix layer 71, which is disposed on the photosensitive layer 15. The third quantum dot matrix layer 71 may be located in a transparent substrate.

[0054] exist Figure 7In addition to red and green quantum dot arrays, the quantum dot array layer may also include a blue quantum dot array, which comprises multiple blue quantum dots arranged in an array. For example, the red quantum dot array comprises multiple red quantum dots 711 (i.e., R-QDCF), the green quantum dot array comprises multiple green quantum dots 712 (i.e., G-QDCF), and the blue quantum dot array comprises multiple blue quantum dots 713 (i.e., B-CF). Adjacent red quantum dots 711, green quantum dots 712, and blue quantum dots 713 can form a quantum dot unit, corresponding to a pixel unit 72.

[0055] It should be noted that, Figure 7 The quantum dot matrix layer can be disposed in the color group (CF) layer of the liquid crystal display panel. The types of red and green quantum dots are different from those of blue quantum dots. When pixel unit 72 emits light, blue light can be emitted directly through the blue quantum dots without affecting the light emission path of the blue light.

[0056] Furthermore, a non-light-emitting area is provided between each of the pixel units, and a light-shielding material is provided in the non-light-emitting area. The light-shielding material is located on the driving circuit layer, wherein the height of the light-shielding material is the same as the height of the pixel unit adjacent to the light-shielding material.

[0057] Figure 8 A schematic diagram of a light-shielding material according to an embodiment of this application is shown.

[0058] like Figure 8 As shown, exemplarily, compared to Figure 5 In this embodiment, the height of the light-shielding material 81 in the non-light-emitting area can be increased so that the height of the light-shielding material is the same as the height of the adjacent pixel unit, that is, the top of the light-shielding material 81 is flush with the top of the adjacent pixel unit. For example, in Figure 8 In this design, the seventh blue LED 841, the eighth blue LED 842, and the ninth blue LED 843 all have the same height and are flush with the height of the adjacent light-shielding material 81. This blocks the light emitted from the side of the light-emitting components in adjacent pixel units, making the light-emitting components a single-sided light source. This reduces the effect of light diffraction emitted by the light-emitting components, making dark areas darker and further increasing the contrast.

[0059] Furthermore, the light-emitting component includes a non-light-emitting side and a light-emitting side facing away from the driving circuit layer, wherein: the light-emitting component is provided with a light-blocking package, and the light-blocking package covers the non-light-emitting side of the light-emitting component.

[0060] Figure 9 This diagram illustrates a light-blocking package according to an embodiment of this application.

[0061] like Figure 9 As shown, exemplarily, compared to Figure 5 In this embodiment of the application, the light-shielding material may not be provided, and the light-emitting component may not be packaged as a die, but rather as a packaging (PKG) process. Figure 9 The light-blocking package 91 in the middle. For example, in Figure 9 In the middle, the left and right sides and bottom of the tenth blue LED 941, the left and right sides and bottom of the eleventh blue LED 942, and the left and right sides and bottom of the twelfth blue LED 943 can all be covered with light-blocking packages. The light-blocking packages 91 cover the light-emitting components from the left and right sides (and may also include the bottom side), thereby blocking the light emitted from the side of the light-emitting components, making the light-emitting components a single-sided light source, thereby reducing the effect of light diffraction emitted by the light-emitting components, making dark areas darker, and further increasing the contrast.

[0062] Because the light emitted by the light-emitting component of this application may diffract, areas that were originally not illuminated (such as between two adjacent quantum dot units) may also be illuminated and cross-linked, thus failing to achieve the effect of making dark areas darker. Therefore, the following is adopted: Figure 8 or Figure 9 This solution blocks light emitted from the side of the light-emitting component, making it a single-sided light source. This reduces the effect of light diffraction, making dark areas darker and further increasing contrast. It should be noted that in this application, Figure 8 and Figure 9 The same approach can also be used simultaneously.

[0063] In addition, Figure 5 , Figure 6 as well as Figure 7 In this process, the aforementioned light-shielding material can be omitted. That is, the photosensitive cross-linked photosensitive layer of this application can also be used alone to replace the black glue and full-surface sealing process in related technologies. After the machine is turned off, the cross-linked and non-cross-linked states of the entire photosensitive layer are preserved. In areas with light, the resin is not cross-linked and is transparent; in areas without light, the resin is cross-linked and is opaque, thereby achieving high contrast.

[0064] In practical applications, this application utilizes diazo-based resin materials as raw materials, combined with molding and extrusion processes, to prepare a photosensitive layer. This photosensitive layer is then cut to the target size, and adhesive is applied to the back of the cut layer. A release film is then attached to the adhesive, thus creating an independent product. In use, the release film can be removed, and the product can be adhered to the target substrate of the display panel.

[0065] The photosensitive layer and the light-emitting layer of the lamp board can be bonded together by molding, offset bonding, or bonding. The photosensitive layer can be applied manually or mechanically. It is understood that there are various methods for preparing the photosensitive layer, and this application does not limit the preparation process of the photosensitive layer.

[0066] Furthermore, this application also provides a display terminal, which includes a terminal body and a display panel, wherein the terminal body is connected to the display panel. The display terminal may include in-vehicle devices, mobile phones, laptops, tablets, commercial advertising equipment, wearable display devices, portable display devices, etc.

[0067] In summary, compared to the use of pure black resin materials with brightness loss as high as 40% in related technologies, this application employs a photosensitive layer. By controlling the "transparent-opaque" state of individual pixels, pixel-level brightness and contrast control can be achieved, reducing brightness loss. Simultaneously, the photosensitive layer has a smooth surface, eliminating flatness and ink color consistency issues. Since the resin is transparent in the areas where pixels emit light and opaque in the areas where no pixels emit light, a significant improvement in pixel-level contrast is achieved. Furthermore, the resin film manufacturing process is simple and easy to mass-produce, improving the manufacturing efficiency of display panels.
