Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and more specifically, to a display panel and a display device. Background Technology
[0002] With the continuous development of display technology, users' demands for display panel products are also constantly increasing. Their expectations extend beyond simply increasing screen size; they also include improving image display quality. Against this backdrop, MiniLED backlight modules have become widely used. By employing smaller LED chips compared to traditional LED backlight technology, MiniLED backlight modules achieve more precise local dimming, improve the contrast and brightness range of the display panel, and thus significantly enhance the realism of colors and the depth of the image, providing viewers with a more immersive and refined visual experience.
[0003] In the MiniLED backlight module, the light emitted by the blue LED chip needs to pass through a quantum dot (QD) film. The blue light excites the quantum dots in the QD film to produce pure red and green light, which is then mixed with the blue light to produce high-quality white light. This white light enters the liquid crystal panel, where the rotation of liquid crystal molecules controls the transmission and blocking of light, thereby displaying the image. Based on this display principle, to prevent more blue light from emanating from the bezel than from the center, phosphor needs to be printed on the reflective strips of the backlight module. These phosphor-printed reflective strips can excite the blue light emitted by the blue LED chip to produce white light, thus solving the blue edge problem.
[0004] However, the above solution is greatly affected by the concentration of the printed phosphor, which can easily cause the border of the display panel to appear bluish or yellowish, resulting in uneven display effect and affecting the overall visual experience of the display panel. Summary of the Invention
[0005] This application provides a display panel and display device that can control the total area of the fluorescent area, thereby improving the phenomenon of bluish or yellowish color on the bezel of the display panel and enhancing the user's visual experience.
[0006] In a first aspect, a display panel is provided, the display panel comprising: a lamp panel assembly including a circuit board and a plurality of light-emitting chips disposed on the circuit board; a first fluorescent component disposed around the lamp panel assembly, the first fluorescent component including a first fluorescent area that converts blue light emitted by the plurality of light-emitting chips into first white light; a second fluorescent component disposed around the first fluorescent component, the second fluorescent component including a second fluorescent area that converts blue light emitted by the plurality of light-emitting chips into second white light; and a transmission component that drives the second fluorescent component to move relative to the first fluorescent component to adjust the overlapping area of the first fluorescent area and the second fluorescent area.
[0007] In this embodiment, the transmission component moves the second fluorescent component relative to the first fluorescent component, thereby adjusting the overlapping area of the first and second fluorescent areas and thus adjusting the total area of the fluorescent area. In this way, when the border area of the display panel exhibits a bluish tint, the total area of the fluorescent area is increased; when the border area of the display panel exhibits a yellowish tint, the total area of the fluorescent area is decreased. This improves the bluish or yellowish tint of the display panel border and enhances the user's visual experience.
[0008] In conjunction with the first aspect, in some implementations of the first aspect, the first fluorescent component further includes a first non-fluorescent region, the first non-fluorescent region including a first groove, the first fluorescent region being disposed in the first groove, and the first non-fluorescent region allowing the second white light to pass through the first fluorescent component.
[0009] In this embodiment, by setting a first non-fluorescent area, the second white light converted by the second fluorescent area can pass through the first non-fluorescent area, thus enabling the second white light to enter the liquid crystal panel and thereby display an image.
[0010] In conjunction with the first aspect, in some implementations of the first aspect, the first fluorescent component further includes a reflective layer disposed on the inner wall of the first groove, the reflective layer being used to reflect the first white light.
[0011] In this embodiment, by setting a reflective layer, the first white light converted by the first fluorescent region can be reflected, preventing the first white light converted by the first fluorescent region from illuminating the second fluorescent region. In this way, not only can the utilization efficiency of white light be improved, but also light interference between different fluorescent regions can be avoided.
[0012] In conjunction with the first aspect, in some implementations of the first aspect, the second fluorescent component further includes a second non-fluorescent region, the second non-fluorescent region including a second groove, the second fluorescent region being disposed in the second groove, and the second non-fluorescent region reflecting the blue light and the second white light emitted by the light-emitting chip.
[0013] In this embodiment, by setting a second non-fluorescent area, the blue light and second white light emitted by the light-emitting chip can be reflected. In this way, not only can the light recycling rate be improved and the waste of light be reduced, but the light output brightness and efficiency of the display panel can also be further improved.
[0014] In conjunction with the first aspect, in some implementations of the first aspect, the second fluorescent region is at the same height as the side of the second non-fluorescent region facing the first fluorescent component.
[0015] In this embodiment, by setting the heights of the sides of the second fluorescent region and the second non-fluorescent region facing the first fluorescent component to be flush, the contact surfaces of the first fluorescent component and the second fluorescent component can be made flatter and smoother, thereby increasing the moving speed of the second fluorescent component relative to the first fluorescent component and thus more efficiently adjusting the overlapping area of the first fluorescent region and the second fluorescent region.
[0016] In conjunction with the first aspect, in some implementations of the first aspect, there are multiple first fluorescent regions and multiple first non-fluorescent regions, with each first fluorescent region disposed between two adjacent first non-fluorescent regions; there are multiple second fluorescent regions and multiple second non-fluorescent regions, with each second fluorescent region disposed between two adjacent second non-fluorescent regions.
[0017] In conjunction with the first aspect, in some implementations of the first aspect, the transmission assembly includes: a first roller, the first roller having its rotation direction controlled by a forward and reverse rotating motor.
[0018] In this embodiment, the rotation direction of the first roller is controlled by a forward and reverse motor, so that the first roller can drive the second fluorescent component to move relative to the first fluorescent component. In this way, the overlapping area of the first fluorescent area and the second fluorescent area can be precisely adjusted, thereby improving the situation where the display panel bezel appears bluish or yellowish.
[0019] In conjunction with the first aspect, in some implementations of the first aspect, the transmission assembly includes: a spring, a second roller, and a locking mechanism, wherein the spring is connected to the second fluorescent component, and the second fluorescent component is wound around the surface of the second roller; when the locking mechanism is in a first state, the spring and the second roller drive the second fluorescent component to move relative to the first fluorescent component.
[0020] In this embodiment, the interaction of the spring, the second roller, and the locking mechanism allows the second phosphor component to move relative to the first phosphor component. This improves the total area of the phosphor region, thereby reducing the bluish or yellowish tint on the display panel bezel. Furthermore, the redundant length of the second phosphor component allows the aforementioned transmission assembly to be used in display panels of different sizes.
[0021] In conjunction with the first aspect, in some implementations of the first aspect, the display panel further includes a plurality of third rollers, the plurality of third rollers being used to control the movement direction of the second fluorescent component.
[0022] In this embodiment, by setting multiple third rollers, it can be ensured that the second fluorescent component is in close contact with the first fluorescent component during movement, thus preventing the second fluorescent component from deviating from the preset movement direction and improving the display reliability and performance of the entire display panel.
[0023] In a second aspect, a display device is provided, the display device including a display panel in any of the implementations of the first aspect described above.
[0024] In conjunction with the second aspect, in some implementations of the second aspect, the display device further includes components such as a housing, a power supply, and control buttons. Attached Figure Description

[0032] In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In this application, "at least one" means one or more, and "more" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.
[0033] The use of prefixes such as "first" and "second" in this application embodiment is solely for distinguishing different descriptive objects and does not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes to distinguish descriptive objects in this application embodiment does not constitute a limitation on the described objects. The description of the described objects is found in the claims or the context of the embodiments, and the use of such prefixes should not constitute unnecessary restrictions.
[0034] The technical solutions in this application will now be described with reference to the accompanying drawings.
[0035] As described in the background section, the light emitted by the blue LED chip in the MiniLED backlight module needs to pass through a quantum dot (QD) film. The blue light excites the quantum dots in the QD film to produce pure red and green light, which are then mixed with the blue light to produce high-quality white light. This white light enters the liquid crystal panel, where the rotation of liquid crystal molecules controls the transmission and blocking of light, thereby enabling image display.
[0036] During image display, a small portion of blue light is transmitted to the bezel of the display panel. Insufficient excitation of this blue light can cause the bezel to appear bluish. Based on this display principle, to prevent the bezel from emitting more blue light than the center, phosphor needs to be printed on the reflective strips of the backlight module. These phosphor-printed reflective strips can excite the blue light emitted by the blue LED chips to produce white light, thus solving the blue edge problem.
[0037] However, the above solution is greatly affected by the concentration of the printed phosphor, which can easily cause the border of the display panel to appear bluish or yellowish, resulting in uneven display effect and affecting the overall visual experience of the display panel.
[0038] This application provides a display panel and a display device that can control the total area of the fluorescent area, thereby improving the phenomenon of bluish or yellowish color on the border of the display panel and enhancing the user's visual experience.
[0039] Figure 1 This is a schematic top view of a display panel provided in an embodiment of this application. The purpose of this schematic view is to facilitate the description of the display panel's structure. Figure 1 The optical films and other components have been hidden.
[0040] like Figure 1 As shown, the display panel includes a lamp panel assembly, a first fluorescent component 103, a second fluorescent component 105, and a transmission assembly 107. The lamp panel assembly includes a circuit board 101 and a plurality of light-emitting chips 102 disposed on the circuit board 101. The first fluorescent component 103 is disposed around the lamp panel assembly and includes a first fluorescent area 104, which is used to convert the blue light emitted by the plurality of light-emitting chips 102 into a first white light. The second fluorescent component 105 is disposed around the first fluorescent component 103 and includes a second fluorescent area 106, which converts the blue light emitted by the plurality of light-emitting chips 102 into a second white light. The transmission assembly 107 is used to drive the second fluorescent component 105 to move relative to the first fluorescent component 103 to adjust the overlap area of the first fluorescent area 104 and the second fluorescent area 106.
[0041] In the aforementioned display panel, the transmission component moves the second phosphor component relative to the first phosphor component, thereby adjusting the overlapping area of the first and second phosphor regions and thus the total area of the phosphor region. In this way, when the bezel area of the display panel exhibits a bluish tint, the total area of the phosphor region can be increased; conversely, when the bezel area exhibits a yellowish tint, the total area of the phosphor region can be decreased. This improves the bluish or yellowish tint of the display panel bezel and enhances the user's visual experience.
[0042] Optionally, the plurality of light-emitting chips 102 may be a plurality of blue LED chips.
[0043] Optionally, the first fluorescent region 104 and the second fluorescent region 106 can be formed by a printing process. The material of the first fluorescent region 104 and the second fluorescent region 106 may include a yellow fluorescent material layer. There are various types of yellow fluorescent material layers, which can be selected appropriately according to actual needs. For example, the yellow fluorescent material layer may include a yellow fluorescent ink layer or a yellow fluorescent adhesive layer. The yellow fluorescent ink layer is formed by mixing fluorescent powder and yellow ink, while the yellow fluorescent adhesive layer can be formed by mixing yellow fluorescent powder and a transparent colloid.
[0044] Optionally, a reflector 111 may be provided around the lamp panel assembly, which can enhance the luminous intensity of the light-emitting chip 102.
[0045] Optionally, the display panel also includes a back plate 110, which supports the lamp panel assembly, the first fluorescent assembly 103, the second fluorescent assembly 105, and the transmission assembly 107. A baffle may be provided on the back plate 110. Figure 1 (Not shown in the image), the height of the barrier wall can be greater than or equal to the height of the second fluorescent component 105, and the second fluorescent component 105 can be installed against the barrier wall. Further optionally, lubricating oil can be applied between the second fluorescent component 105 and the barrier wall to facilitate the movement of the second fluorescent component 105 relative to the first fluorescent component 103.
[0046] Optionally, the first fluorescent region 104 and the second fluorescent region 106 can be of any shape. For example, the first fluorescent region 104 and the second fluorescent region 106 can be curved or straight.
[0047] In one possible implementation, such as Figure 2 As shown, the first fluorescent component 103 also includes a first non-fluorescent region 108, the first non-fluorescent region 108 includes a first groove, the first fluorescent region 104 is disposed in the first groove, and the first non-fluorescent region 108 allows the second white light to pass through the first fluorescent component 103.
[0048] Based on the aforementioned display panel, by setting the first non-fluorescent area, the second white light converted from the second fluorescent area can pass through the first non-fluorescent area, thus enabling the second white light to enter the liquid crystal panel and thereby display the image.
[0049] Optionally, the first groove may be provided on the side facing the lamp panel assembly, and the thickness of the first groove is less than the thickness of the first non-fluorescent area 108.
[0050] Optionally, the first non-fluorescent region 108 can be made of a highly transparent material. For example, the first non-fluorescent region 108 can be made of polycarbonate (PC) or polymethyl methacrylate (PMMA). PC and PMMA can ensure that the first non-fluorescent region 108 can transmit light while giving the first non-fluorescent region 108 a certain rigidity.
[0051] In one possible implementation, such as Figure 2 As shown, the first fluorescent component 103 also includes a reflective layer 112, which is disposed inside the first groove, that is, at the position where the first fluorescent area 104 and the first non-fluorescent area 108 are in contact. The reflective layer 112 is used to reflect the first white light.
[0052] Based on the aforementioned display panel, by setting up a reflective layer, the first white light converted by the first fluorescent area can be reflected, preventing the first white light converted by the first fluorescent area from illuminating the second fluorescent area. In this way, not only can the utilization efficiency of white light be improved, but also light interference between different fluorescent areas can be avoided.
[0053] In one possible implementation, such as Figure 3 As shown, the second fluorescent component 105 also includes a second non-fluorescent region 109, which includes a second groove. The second fluorescent region 106 can be disposed in the second groove. The second non-fluorescent region 109 reflects the blue light and the second white light emitted by the light-emitting chip.
[0054] Based on the aforementioned display panel, the setting of the second non-fluorescent area can reflect the blue light and the second white light emitted by the light-emitting chip. In this way, not only can the light recycling rate be improved and the waste of light be reduced, but the light output brightness and efficiency of the display panel can also be further improved.
[0055] Optionally, the second groove can be disposed on the side facing the first fluorescent component 103, and the thickness of the second groove is less than the thickness of the second non-fluorescent region 109.
[0056] Optionally, the second non-fluorescent region 109 can be made of flexible polyethylene terephthalate (PET) material, giving it the same function as a reflective sheet, which can reflect the blue light and second white light emitted by the light-emitting chip to make full use of the light.
[0057] In one possible implementation, such as Figure 4 As shown, the second fluorescent region 106 and the second non-fluorescent region 109 are at the same height on the side facing the first fluorescent component 103.
[0058] In this embodiment, by setting the heights of the sides of the second fluorescent region and the second non-fluorescent region facing the first fluorescent component to be flush, the contact surfaces of the first fluorescent component and the second fluorescent component can be made flatter and smoother, thereby increasing the moving speed of the second fluorescent component relative to the first fluorescent component and thus more efficiently adjusting the overlapping area of the first fluorescent region and the second fluorescent region.
[0059] The following is combined with Figure 5 Explain in detail how the overlap area of the first fluorescent region 104 and the second fluorescent region 106 affects the total area of the fluorescent region.
[0060] Figure 5 This is a schematic diagram illustrating the area change of the overlapping region of the fluorescent region provided in an embodiment of this application. Figure 5 (a) in the diagram is a schematic diagram showing the first fluorescent region 104 and the second fluorescent region 106 in an overlapping state. Figure 5 (b) is a schematic diagram showing that the first fluorescent region 104 and the second fluorescent region 106 are in a staggered state.
[0061] like Figure 5 As shown in (a), in the initial state, the first fluorescent region 104 and the second fluorescent region 106 completely overlap. At this time, the overlap area of the first fluorescent region 105 and the second fluorescent region 106 is the largest, and the total area of the fluorescent region is the smallest. When a bluish tint appears on the border of the display panel, the transmission component 107 can drive the second fluorescent component 105 to move relative to the first fluorescent component 103 to adjust the overlap area of the first fluorescent region 104 and the second fluorescent region 106. Ultimately, this can achieve the desired effect. Figure 5 The state is shown in (b) in the figure. During this process, the overlapping area of the first fluorescent region 104 and the second fluorescent region 106 gradually decreases, and the total area of the fluorescent region (the sum of the non-overlapping area and the overlapping area of the first fluorescent region 104 and the second fluorescent region 106) gradually increases. As the total area of the fluorescent region increases, the phenomenon of the display panel bezel being bluish is also eliminated.
[0062] It should be noted that, Figure 5 The process of adjusting the area of the overlapping region of the first fluorescent region 104 and the second fluorescent region 106 shown is merely an illustrative example, and this application does not limit the adjustment process of the first fluorescent region 104 and the second fluorescent region 106.
[0063] In one possible implementation, such as Figure 1 As shown, the transmission assembly 107 includes a first roller 1071, the first roller 1071 having its rotation direction controlled by a forward and reverse motor.
[0064] Based on the aforementioned display panel, the rotation direction of the first roller is controlled by a forward and reverse motor, allowing the first roller to move the second fluorescent component relative to the first fluorescent component. In this way, the overlapping area of the first fluorescent area and the second fluorescent area can be precisely adjusted, thereby improving the situation where the display panel frame appears bluish or yellowish.
[0065] For example, when the reversible motor rotates in the forward direction, it can drive the first roller 1071 to rotate in the clockwise direction, and when the reversible motor rotates in the reverse direction, it can drive the first roller 1071 to rotate in the counterclockwise direction.
[0066] Optionally, such as Figure 6 As shown, there are multiple first fluorescent regions 104 and first non-fluorescent regions 108, with each first fluorescent region 104 positioned between two adjacent first non-fluorescent regions 108; there are multiple second fluorescent regions 106 and second non-fluorescent regions 109, with each second fluorescent region 106 positioned between two adjacent second non-fluorescent regions 109. Furthermore, there can also be multiple first rollers 1071, which can be distributed at the corners of the backplate 110.
[0067] Optionally, in Figure 6 In the process, the spacing between multiple first fluorescent regions 104 can be the same or different, and similarly, the spacing between multiple second fluorescent regions 106 can be the same or different.
[0068] Optionally, in Figure 6 In this process, the width and length of the multiple first fluorescent regions 104 can be the same or different. Similarly, the width and length of the multiple second fluorescent regions 106 can be the same or different.
[0069] In one possible implementation, such as Figure 7 As shown, the transmission assembly 107 includes: a spring 1072, a second roller 1073, and a locking mechanism 1074. The spring 1072 is connected to the second fluorescent component 105, and the second fluorescent component 105 is wound around the surface of the second roller 1073. When the locking mechanism 1074 is in the first state, the spring 1072 and the second roller 1073 drive the second fluorescent component 105 to move relative to the first fluorescent component 103.
[0070] Based on the aforementioned display panel, the interaction of the spring, the second roller, and the locking mechanism allows the second phosphor component to move relative to the first phosphor component. This improves the overall area of the phosphor region, thereby reducing the bluish or yellowish tint appearing on the display panel bezel. Furthermore, the redundant length of the second phosphor component allows the aforementioned transmission assembly to be used in display panels of different sizes.
[0071] Optionally, when the locking mechanism 1074 is in the second state, the second fluorescent component 105 can be fixed relative to the first fluorescent component 103.
[0072] For example, the spring 1072 and the second roller 1073 drive the second fluorescent component 105 to move relative to the first fluorescent component 103, including: when the locking mechanism 1074 is in a first state, the spring 1072 contracts, driving the second fluorescent component 105 to move relative to the first fluorescent component 103. When the distance moved is equal to a preset distance, the locking mechanism 1074 is in a second state, fixing the second fluorescent component 105 relative to the first fluorescent component.
[0073] Optionally, the first state can be a non-locked state, and the second state can be a locked state.
[0074] In one possible implementation, such as Figure 7 As shown, the display panel also includes a plurality of third rollers 113, which are used to control the movement direction of the second phosphor component 105.
[0075] Based on the aforementioned display panel, the arrangement of multiple third rollers ensures that the second phosphor component remains in close contact with the first phosphor component during movement, preventing the second phosphor component from deviating from the preset movement direction, thereby improving the display reliability and performance of the entire display panel.
[0076] Optionally, such as Figure 8 As shown, there are multiple first fluorescent regions 104 and first non-fluorescent regions 108, with each first fluorescent region 104 disposed between two adjacent first non-fluorescent regions 108; there are multiple second fluorescent regions 106 and second non-fluorescent regions 109, with each second fluorescent region 106 disposed between two adjacent second non-fluorescent regions 109. Furthermore, multiple third rollers 113 are disposed along the surface of the second fluorescent assembly 105.
[0077] Optionally, in Figure 8 In the process, the spacing between multiple first fluorescent regions 104 can be the same or different, and similarly, the spacing between multiple second fluorescent regions 106 can be the same or different.
[0078] Optionally, in Figure 8 In this process, the width and length of the multiple first fluorescent regions 104 can be the same or different. Similarly, the width and length of the multiple second fluorescent regions 106 can be the same or different.
[0079] This application also provides a display device, including a display panel in any of the above embodiments.
[0080] Optionally, the display device may also include components such as a housing, a power supply, and control buttons.
[0081] Optionally, the display device may be at least one of the following: smartphone, tablet personal computer, mobile phone, video phone, e-book reader, laptop PC, netbook computer, workstation, server, personal digital assistant, portable multimedia player, MP3 player, mobile medical device, camera, game console, digital camera, car navigation system, electronic billboard, ATM, smart bracelet, smartwatch, virtual reality (VR) device, or wearable device.
[0082] It should be noted that, unless otherwise specified or there is a logical conflict, the terminology and / or descriptions of the various implementations in this application are consistent and can be referenced by each other. The technical features in different implementations can be combined to form new embodiments based on their inherent logical relationships.
[0083] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
