Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a lamp panel and display device. Background Technology

[0002] For traditional LCD display devices, the backlight module uses LED (Mini LED) as the backlight source, and generates white light through color conversion materials (KSF, YAG, QD, etc.). The sub-pixels on the LCD panel perform RGB spatial adjustment to achieve full-color display.

[0003] With the trend towards larger screens, users are increasingly demanding high image quality and low power consumption. Employing multi-primary-color backlighting (such as RGB three-color backlighting) allows for full-color backlighting through independent control of the primary colors, reducing image signal loss, improving color saturation, and enhancing the image quality of LCD displays. Furthermore, compared to traditional local dimming, full-color backlighting (Color Local Dimming) can adaptively adjust the backlight based on the image content, turning off or reducing unwanted backlight colors at any time, thereby achieving system energy savings.

[0004] Multi-color backlighting can also be applied to field-sequence displays. Since its liquid crystal display panel does not have the filtering effect of a color filter layer, the light transmittance of the display module can be increased to about 3 times that of the original, which can effectively reduce the power consumption of the liquid crystal display panel while improving the image quality.

[0005] Currently, the main representative of multi-primary-color backlight modules is the RGB tri-color backlight module. In an RGB tri-color backlight module, multiple RGB LEDs are arranged in an array on the light board. Each RGB LED contains a red, green, and blue LED chip within a single LED package. Therefore, compared to traditional LED backlight modules, the light-emitting angle of the LEDs in a multi-primary-color backlight module is somewhat limited, and the wiring on the light board becomes more complex, leading to increased driving and manufacturing costs. Summary of the Invention

[0006] This application provides a lamp board and a display device. The lamp board can reduce the cost of using lamp beads and the manufacturing cost of the substrate, thereby reducing the overall manufacturing cost of the lamp board.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A light panel, comprising:

[0009] The substrate, the first side of the substrate comprising:

[0010] Multiple light output zones;

[0011] Multiple lamp groups are located on the first side of the substrate, and the multiple lamp groups are arranged one-to-one within the multiple light-emitting zones. Each lamp group includes:

[0012] Multiple LED beads, each LED bead having a light-emitting top surface located on the side of the LED bead away from the substrate, and the light-emitting top surface being the light-emitting surface;

[0013] In the lamp assembly, the plurality of lamp beads include at least a plurality of first lamp beads, which are arranged circumferentially in the corresponding light-emitting zones. The light-emitting top surface of the first lamp beads is not parallel to the first side surface of the substrate, and the light-emitting top surface of the first lamp beads is inclined towards the outside of the light-emitting zone.

[0014] The lamp panel in the above technical solution has the following beneficial effects: the first side of the substrate has multiple light-emitting zones, and each light-emitting zone is provided with a lamp group. Multiple first lamp beads in the lamp group are arranged circumferentially in the corresponding light-emitting zone. Since the light-emitting top surface of the first lamp bead is tilted towards the outside of the light-emitting zone, the light-emitting angle of the lamp group can be increased, realizing the design of a large light-emitting angle for the light-emitting zone.

[0015] Furthermore, while ensuring the light output effect, it can reduce the number of LEDs used in each light output zone, thereby reducing the complexity of wiring on the substrate, which in turn reduces the cost of LEDs on the light board and the manufacturing cost of the substrate, thus reducing the overall manufacturing cost of the light board.

[0016] In some embodiments of this application, the lamp assembly further includes:

[0017] At least one second LED, wherein the light-emitting top surface of the second LED is parallel to the first side surface of the substrate;

[0018] The plurality of first LED beads are arranged around the at least one second LED bead.

[0019] The lamp panel in the above technical solution has the following beneficial effects: In the lamp group, multiple first lamp beads can be arranged around second lamp beads, the light-emitting top surface of the second lamp beads can be parallel to the first side surface of the substrate, the light-emitting top surface of the second lamp group and the first lamp beads have different orientations, and the light emission uniformity of the light emission zone can be improved by the cooperation of the second lamp beads and the first lamp beads.

[0020] In some embodiments of this application, the multiple LEDs in the lamp assembly are arranged in a matrix; or,

[0021] The multiple first LED beads in the lamp assembly are distributed in an equilateral polygon.

[0022] The lamp board in the above technical solution has the following beneficial effects: multiple lamp beads in the lamp group can be distributed in a matrix, or multiple first lamp beads in the lamp group can be distributed in an equilateral polygon, which can make the lamp beads in the lamp group evenly distributed, improve the light output uniformity of the light output zone, and the lamp beads on the lamp board have a simple arrangement pattern, making the lamp board easy to manufacture.

[0023] In some embodiments of this application, in the lamp assembly, the angle between the light-emitting top surface of each of the first lamp beads and the first side surface of the substrate is equal.

[0024] The lamp panel in the above technical solution has the following beneficial effects: the angle between the top surface of each first lamp bead in the lamp group and the first side surface of the substrate is equal, which can ensure that the light emission angle around the light emission zone is consistent and optimize the light emission effect of the lamp panel.

[0025] In some embodiments of this application, the light-emitting top surfaces of the plurality of first lamp beads in the lamp assembly are oriented in at least two directions.

[0026] The lamp board in the above technical solution has the following beneficial effects: the light-emitting top surface of the multiple first lamp beads in the lamp group is oriented in at least two directions, and the light-emitting top surface of the multiple first lamp beads in the lamp group is set at an angle to achieve a large light-emitting angle design for light-emitting zones.

[0027] In some embodiments of this application, in the lamp group, the light-emitting top surfaces of the plurality of first lamp beads have different orientations, and the included angle between the light-emitting top surfaces of two adjacent first lamp beads along the circumferential direction is the first included angle, and any first included angle is equal.

[0028] The lamp panel in the above technical solution has the following beneficial effects: In the lamp group, the included angle of the light-emitting top surface of any two adjacent first lamp beads along the circumference is equal, which can ensure the uniformity of light emission around the light emission zone and ensure the light emission effect of the lamp panel.

[0029] In some embodiments of this application, a light diffusion section is disposed on the light-emitting top surface of the lamp bead, and the light diffusion section is configured to make the light-emitting top surface emit light uniformly.

[0030] The lamp board in the above technical solution has the following beneficial effects: a light diffusion part is provided on the light-emitting top surface of the lamp bead, which can make the light emission from the light-emitting top surface of the lamp bead more uniform, thereby ensuring that the light emission from the light-emitting zone is more uniform.

[0031] In some embodiments of this application, the first side of the substrate has multiple driving zones, and multiple lamp groups are evenly distributed within the multiple driving zones;

[0032] The light panel also includes:

[0033] Multiple driver modules are set in multiple driver partitions, one-to-one, and the driver modules are used to drive the lamp groups in their respective driver partitions.

[0034] The substrate includes:

[0035] Multiple first wiring lines are provided, through which multiple LED beads in the lamp group are connected in series sequentially.

[0036] Multiple second wirings are provided, through which the drive module is electrically connected to the LED beads connected in series in the lamp group.

[0037] The lamp board in the above technical solution has the following beneficial effects: Since the light-emitting top surface of the first lamp bead in the lamp group is designed as a slope, it can realize a large light-emitting angle design for the light-emitting zone. This can reduce the number of lamp beads used in the lamp group while ensuring the light-emitting effect, thereby reducing the number of first wirings and the area occupied, and increasing the usable area of ​​the second wirings. Therefore, it can reduce the wiring difficulty on the substrate and reduce the manufacturing cost of the substrate.

[0038] In some embodiments of this application, the spacing between two adjacent lamp groups is a first spacing;

[0039] In the lamp assembly, the spacing between two adjacent lamp beads is the second spacing, which is smaller than the first spacing.

[0040] The lamp board in the above technical solution has the following beneficial effects: by setting the second spacing to be smaller than the first spacing, the area occupied by the first wiring connecting the lamp beads can be further reduced, while the usable area of ​​the second wiring connecting the driver module and the lamp group can be increased, which can reduce the manufacturing difficulty of the substrate and thus reduce the manufacturing cost of the substrate.

[0041] This application also provides a display device, including any of the lamp panels provided in the above-described technical solutions. Attached Figure Description

[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] In related technologies, RGB tri-color backlight modules provide light output through a light panel; such as Figure 1 As shown, the lamp panel includes a substrate 01 and multiple LED chips 02 located on the substrate 01. The main structure of the LED chips 02 can be as follows: Figure 2 As shown, the lamp bead 01 contains at least three LED chips 021 with different emitting colors. For example, the lamp bead 02 contains a red LED chip, a green LED chip, and a blue LED chip.

[0063] Specifically, the arrangement of multiple LED beads 02 on the light panel can be as follows: Figure 1 As shown, multiple LED beads 02 can be arranged in an array, with the top surface of each LED bead 02 parallel to the extended surface of the substrate. The multiple LED beads 02 can be divided into multiple LED groups A, which are also arranged in an array. In each LED group A, multiple LED beads 02 can be connected sequentially through the first trace 04 on the substrate 01.

[0064] The lamp board also includes multiple driving modules located on the substrate 01. Each driving module can drive the lamp beads in multiple lamp groups to emit light. The driving element 03 can be electrically connected to the lamp group A through the second trace on the substrate 01.

[0065] Specifically, the driving module may include multiple driving elements 03 that correspond one-to-one with multiple LED chips in the lamp bead, and the driving elements 03 can be used to drive the state of the corresponding LED chip.

[0066] Compared with traditional LED backlight modules, the manufacturing process of LED chips in multi-color backlight modules is more complex, making mass production difficult, and the light emission angle is limited. Similarly, the wiring on the substrate 01 becomes more complicated, which increases the overall manufacturing cost of the light board.

[0067] Please refer to Figure 3 and Figure 4 This application provides a light panel, comprising:

[0068] Substrate 1, the first side of substrate 1 includes multiple light-emitting zones B;

[0069] Multiple lamp groups 2 are located on the first side of the base 1. The multiple lamp groups 2 are arranged in multiple light-emitting zones B in a one-to-one correspondence. Each lamp group 2 includes multiple lamp beads 21. Each lamp bead 21 has a light-emitting top surface D. The light-emitting top surface D is located on the side of the lamp bead 21 away from the base 1. The light-emitting top surface D is the light emission surface.

[0070] In the lamp group 2, the multiple lamp beads 21 include at least multiple first lamp beads 201. The multiple first lamp beads 201 are arranged circumferentially in the corresponding light-emitting zone B. The light-emitting top surface D of the first lamp bead 201 is not parallel to the first side surface of the substrate 1, and the light-emitting top surface D of the first lamp bead 201 is inclined towards the outside of the light-emitting zone.

[0071] In the lamp panel provided in this application embodiment, the first side of the substrate 1 has multiple light-emitting zones B, and each light-emitting zone B is provided with a lamp group 2. Multiple first lamp beads 201 in the lamp group 2 are arranged circumferentially in the corresponding light-emitting zone B. Since the light-emitting top surface D of the first lamp bead 201 is inclined towards the outside of the light-emitting zone, the light-emitting angle of the lamp group 2 can be increased, realizing the design of a large light-emitting angle of the light-emitting zone B.

[0072] Based on this design, while ensuring the light output effect, compared with related technologies, it can also reduce the number of LEDs 21 used in each light output zone B, thereby reducing the complexity of wiring on the substrate, and thus reducing the cost of using LEDs 21 on the light board and the manufacturing cost of the substrate, thereby reducing the overall manufacturing cost of the light board.

[0073] like Figure 3 The diagram shows the arrangement of multiple lamp groups 2 on the lamp panel. The multiple lamp groups 2 can be arranged in an array, and each lamp group 2 is located in a light-emitting zone B of the substrate.

[0074] Optionally, the multiple light groups 2 on the light panel can also be arranged in a honeycomb pattern or other arrangements. There are no restrictions here, and it depends on the actual situation.

[0075] In some embodiments of this application, the above-mentioned lamp bead 21 may have a base, at least one light-emitting element 211 and a protective shell. The base is disposed on the substrate 1, the light-emitting element 211 is disposed on the base, and the protective shell covers the outside of the light-emitting element 211.

[0076] Among them, the light-emitting top surface D of the lamp bead 21 can be the top surface of the protective shell away from the substrate 1.

[0077] Specifically, the lamp bead 21 may have at least three light-emitting elements 211 inside, and the light-emitting elements 211 emit different colors, which can make the lamp panel emit light of different colors to realize a multi-color backlight module.

[0078] For example, LED bead 21 may have red, green, and blue light-emitting elements. Alternatively, LED bead 21 may also have at least three light-emitting elements of other different colors; this is not limited here and depends on the actual situation.

[0079] Specifically, the light-emitting element 211 can be an LED chip, and the lamp bead 2 can be an RGB LED lamp bead.

[0080] Specifically, the aforementioned protective shell can be injection molded.

[0081] When the LED bead 2 has multiple light-emitting elements, the manufacturing process of such LED bead is complex and not easy to mass-produce. However, the lamp board provided in this application embodiment can realize the design of a large light emission angle in the light emission zone. Based on this, the number of LED beads 21 used in the light emission zone B can be reduced, thereby reducing the cost of using LED beads 21 on the lamp board.

[0082] In some embodiments of this application, the first side of the substrate may include multiple driving zones, and multiple lamp groups may be evenly distributed within the multiple driving zones;

[0083] The light panel may also include multiple driver modules 3, which can be located in multiple driver partitions in a one-to-one correspondence. The driver module 3 can be used to drive the light group 2 in the driver partition where it is located.

[0084] For example, such as Figure 5 As shown, each drive zone can have two rows of light groups 2, and the drive module 3 can be set between the two rows of light groups 2. The drive module 3 can drive the LED beads 21 in the adjacent two rows of light groups 2 to emit light.

[0085] Specifically, the number of lamp groups that the drive module 3 can drive and the setting position of the drive module 3 are not limited here and can be determined according to the actual situation.

[0086] In some embodiments of this application, the substrate 1 may include a routing layer, which includes multiple first traces L and multiple second traces;

[0087] In this lamp group 2, multiple LED beads 21 can be electrically connected sequentially via the first wiring L, and the driving module 3 can be electrically connected to the lamp group 2 via the second wiring, so that the driving module 3 can drive the LED beads 21 in the lamp group to emit light.

[0088] For example, such as Figure 6 As shown, in lamp group 2, four LED beads 21 are connected in series through the first wiring L, and the four connected LED beads 21 can be connected to the drive module 3 through the second wiring.

[0089] In the aforementioned light board, based on the large light emission angle design of the light group 2, while ensuring the light emission effect of the light emission zone, the number of LED beads 21 used in the light group 2 can be reduced, thereby reducing the number and area occupied by the first wiring L, and increasing the usable area of ​​the second wiring. In this way, a single layer of wiring can be installed on the substrate 1, which can simplify the manufacturing process of the substrate 1 and reduce the manufacturing cost of the substrate 1.

[0090] Specifically, when the lamp bead 21 includes at least three light-emitting elements 211, each driving module 3 may include at least three driving elements 31, and the at least three driving elements 31 correspond one-to-one with the at least three light-emitting elements 211 in the lamp bead 21. The driving elements 31 can drive the corresponding light-emitting elements 211 to emit light.

[0091] For example, such as Figure 5 As shown, the LED bead 21 may include a red light-emitting element, a green light-emitting element, and a blue light-emitting element;

[0092] In lamp group 2, the red light-emitting elements of multiple lamp beads are connected in series sequentially through the first wiring, the green light-emitting elements of multiple lamp groups are connected in series sequentially through the first wiring, and the blue light-emitting elements of multiple lamp beads are connected in series sequentially through the first wiring.

[0093] The drive module may include a first drive element 311, a second drive element 312, and a third drive element 313;

[0094] The first driving element 311 can be electrically connected to the red light-emitting element 211 connected in series in the lamp group through the second wiring. The first driving element 311 is used to drive the red light-emitting element 211 in the lamp bead 21 to emit light.

[0095] The second driving element 312 can be electrically connected to the green light-emitting element 211 connected in series in the lamp group through the second wiring. The second driving element 312 is used to drive the green light-emitting element 211 in the lamp bead 21 to emit light.

[0096] The third driving element 313 can be electrically connected to the red light-emitting element 211 connected in series in the lamp group through the second wiring, and the third driving element 312 can be used to drive the blue light-emitting element 211 in the lamp bead 21 to emit light.

[0097] Specifically, the aforementioned driving element 31 can be a driving IC.

[0098] The aforementioned substrate 1 can be a PCB substrate or a substrate of other materials. There are no restrictions here, and it depends on the actual situation.

[0099] In some embodiments of this application, the spacing between two adjacent lamp groups 2 is a first spacing P1; while in lamp group 2, the spacing between two adjacent lamp beads 21 is a second spacing P2, the second spacing P2 being smaller than the first P1, such as... Figure 14 As shown.

[0100] In the aforementioned light board, by setting the second spacing to be smaller than the first spacing, the area occupied by the first wiring L connecting the LED beads 21 can be further reduced, while increasing the available area of ​​the second wiring connecting the driver module and the lamp group. This can reduce the manufacturing difficulty of the substrate 1 and thus reduce the manufacturing cost of the substrate 1.

[0101] In some embodiments of this application, the above-mentioned lamp group 2 may include only a plurality of first lamp beads 201, that is, the light-emitting top surface D of each lamp bead 21 in the lamp group 2 is inclined towards the outside of the light-emitting zone where it is located, which can increase the light-emitting angle of the light-emitting zone B.

[0102] Specifically, the number of LED beads 21 in the above-mentioned light group 2 is not limited here, and depends on the actual situation.

[0103] For example, such as Figure 3 and Figure 4 As shown, each lamp group 2 includes four lamp beads 21, which are arranged circumferentially within the light-emitting zone. The light-emitting top surface D of each lamp bead 21 is an inclined surface that is not parallel to the first side surface of the substrate 1, and the light-emitting top surface of the lamp bead 21 is inclined towards the outside of the light-emitting zone, which can increase the light-emitting angle of the light-emitting zone B.

[0104] like Figure 7 As shown, each lamp group 2 includes 6 lamp beads 21, which are arranged circumferentially within the light-emitting zone. The light-emitting top surface D of each lamp bead 21 is an inclined surface that is not parallel to the first side surface of the substrate 1, and the light-emitting top surface of the lamp bead 21 is inclined towards the outside of the light-emitting zone, which can increase the light-emitting angle of the light-emitting zone B.

[0105] like Figure 8 As shown, each lamp group 2 includes 8 lamp beads 21, which are arranged circumferentially within the light-emitting zone. The light-emitting top surface D of each lamp bead 21 is an inclined surface that is not parallel to the first side surface of the substrate 1, and the light-emitting top surface of the lamp bead 21 is inclined towards the outside of the light-emitting zone, which can increase the light-emitting angle of the light-emitting zone B.

[0106] like Figure 9 and Figure 10 As shown, each lamp group 2 may also include 3 lamp beads 21. The 3 lamp beads are arranged circumferentially within the light-emitting zone. The light-emitting top surface D of each lamp bead 21 is an inclined surface that is not parallel to the first side surface of the base 1, and the light-emitting top surface of the lamp bead 21 is inclined towards the outside of the light-emitting zone, which can increase the light-emitting angle of the light-emitting zone B.

[0107] In some embodiments of this application, the lamp assembly 2 may further include at least one second lamp bead 202, such as Figure 11As shown, the light-emitting top surface D of the second lamp bead 202 can be parallel to the first side surface of the substrate 1, and a plurality of first lamp beads 201 are arranged around at least one second lamp bead 202.

[0108] Specifically, in the above-mentioned lamp group 2, the first lamp bead 201 and the second lamp bead 202 work together to achieve a large light emission angle design for the light emission zone B. In addition, in the lamp group, the light emission top surfaces of the second lamp bead 202 and the first lamp bead 201 face different directions, which can improve the light emission uniformity of the light emission zone B.

[0109] Specifically, the number of the first LED 201 and the second LED 202 in the above-mentioned LED 2 are not limited here, and are determined according to the actual situation.

[0110] For example, such as Figure 11 As shown, each lamp group 2 includes 9 lamp beads 21, one lamp bead 21 is the second lamp bead 202, and the other 8 lamp beads 21 are the first lamp beads 201, arranged around the second lamp bead 202.

[0111] Among them, the light-emitting top surface of one second lamp bead 202 is perpendicular to the first side surface of the substrate, while the light-emitting top surface D of the other eight first lamp beads 201 is inclined to the outside of the light-emitting zone, which can both increase the light-emitting angle of the light-emitting zone B and improve the light-emitting uniformity of the light-emitting zone B.

[0112] like Figure 12 As shown, each lamp group 2 includes 5 lamp beads 21, one lamp bead 21 is the second lamp bead 202, and the other 4 lamp beads 21 are the first lamp beads 201, arranged around the second lamp bead 202.

[0113] Among them, the light-emitting top surface of one second lamp bead 202 is perpendicular to the first side surface of the substrate, while the light-emitting top surface D of the four first lamp beads 201 is inclined to the outside of the light-emitting zone, which can both increase the light-emitting angle of the light-emitting zone B and improve the light-emitting uniformity of the light-emitting zone B.

[0114] like Figure 13 As shown, each lamp group 2 includes 7 lamp beads 21, one lamp bead 21 is the second lamp bead 202, and the other 6 lamp beads 21 are the first lamp beads 201, arranged around the second lamp bead 202.

[0115] Among them, the light-emitting top surface of one second lamp bead 202 is perpendicular to the first side surface of the substrate, while the light-emitting top surface D of the six first lamp beads 201 is inclined to the outside of the light-emitting zone, which can both increase the light-emitting angle of the light-emitting zone B and improve the light-emitting uniformity of the light-emitting zone B.

[0116] Or, such as Figure 14As shown, each lamp group 2 may include 9 lamp beads 21, the middle 3 lamp beads 21 can be second lamp beads 202, and the other 6 lamp beads 21 are first lamp beads 201, distributed on both sides of the 3 second lamp beads 202.

[0117] Among them, the light-emitting top surfaces of the three second lamp beads 202 are perpendicular to the first side surface of the substrate, while the light-emitting top surfaces D of the six first lamp beads 201 are inclined to the outside of the light-emitting zone. This can increase the light-emitting angle of the light-emitting zone B and improve the light-emitting uniformity of the light-emitting zone B.

[0118] In some embodiments of this application, the multiple LED beads 21 in the lamp group 2 can be distributed in a matrix, so that the LED beads in the lamp group are evenly distributed, which can improve the light emission uniformity of the light emission zone; and the arrangement pattern of the LED beads 21 on the lamp board is simple, making the lamp board easy to manufacture.

[0119] For example, such as Figure 4 , Figure 7 , Figure 8 as well as Figure 11 As shown, Figure 4 The LED beads 21 in the middle lamp group 2 are arranged in a 2*2 array. Figure 7 The LED beads 21 in the middle lamp group 2 are arranged in a 2*3 array. Figure 8 The LED beads 21 in the middle lamp group 2 are arranged in a 2*4 array. Figure 11 The LED beads 21 in the middle lamp group 2 are arranged in a 3*3 array.

[0120] Optionally, the multiple first LED beads 201 in the lamp group 2 can also be distributed in an equilateral polygon, so that the LED beads in the lamp group are evenly distributed, which can improve the light output uniformity of the light output zone. In addition, the arrangement pattern of the LED beads 21 on the lamp board is simple, making the lamp board easy to manufacture.

[0121] For example, such as Figure 9 As shown, Figure 9 Each lamp group 2 includes 3 first lamp beads 201, but does not include second lamp beads 202. The 3 first lamp beads 201 can be distributed in an equilateral triangle.

[0122] like Figure 12 As shown, Figure 12 Each lamp group 2 includes four first lamp beads 201 and one second lamp bead 202. The four first lamp beads 201 can be arranged in a square, and one second lamp bead 202 is located between the four first lamp beads 201. The distance between the second lamp bead 202 and the four first lamp beads 201 can be equal.

[0123] like Figure 13 As shown, Figure 13Each lamp group 2 includes 6 first lamp beads 201 and one second lamp bead 202. The 6 first lamp beads 201 can be arranged in a square, and the 1 second lamp bead 202 is located between the 6 first lamp beads 201. The distance between the second lamp bead 202 and the 6 first lamp beads 201 can be equal.

[0124] Specifically, the arrangement of the LED beads 21 in the lamp group 2 can also be in other ways, which are not limited here.

[0125] In some embodiments of this application, the arrangement of LED beads 21 in two adjacent lamp groups 2 can be the same, such as... Figure 12 , Figure 13 and Figure 14 As shown.

[0126] Alternatively, the arrangement of LED beads 21 in two adjacent light groups 2 can also be different, such as... Figure 9 As shown, Figure 9 In two adjacent light groups 21, the number of LED beads 21 is the same, but the arrangement is different.

[0127] Optionally, the arrangement of LED beads 21 in two adjacent light groups 2 is not limited here and can be determined according to the actual situation.

[0128] In some embodiments of this application, in the lamp group 2, the angle between the light-emitting top surface D of each first lamp bead 201 and the first side surface of the substrate 1 is equal, which can ensure that the light-emitting angles around the light-emitting partition B are consistent and optimize the light-emitting effect of the lamp board.

[0129] For example, such as Figure 4 As shown, each lamp group 2 includes 4 first lamp beads 201. The angle between the light-emitting top surface D of the 4 first lamp beads 201 and the first side surface of the substrate 1 is equal, which can ensure that the light-emitting angles around the light-emitting zone B are consistent.

[0130] Specifically, the angle between the light-emitting top surface D of the LED 21 and the first side surface of the substrate 1 is not limited here, and can be determined according to the backlight requirements of the backlight module, such as the driving voltage and light emission brightness.

[0131] In some embodiments of this application, in the lamp group 2, the orientation of the light-emitting top surface D of the plurality of first lamp beads 201 includes at least two directions, which can realize the design of a large light-emitting angle of the light-emitting zone B.

[0132] For example, such as Figure 7 and Figure 8 As shown, the lamp group 2 includes two rows of lamp beads 21. The light-emitting top surface D of the first row of lamp beads 21 can be designed to face the same direction, while the light-emitting top surface D of the second row of lamp beads 21 faces the same direction, and the light-emitting top surface D of the two rows of lamp beads 21 faces different directions.

[0133] Or, such as Figure 9 As shown, the lamp assembly includes three rows of LED beads 21. The top light-emitting surfaces D of the first row of LED beads 21 can be designed to face the same direction, the top light-emitting surfaces D of the second row of LED beads 21 can face the same direction, the top light-emitting surfaces D of the third row of LED beads 21 can face the same direction, and the top light-emitting surfaces D of the three rows of LED beads 21 can face different directions.

[0134] In some embodiments of this application, in the lamp group 2, the orientation of the light-emitting top surface D of each first lamp bead 201 can be different, and the included angle between the light-emitting top surfaces of two adjacent first lamp beads 201 along the circumferential direction is the first included angle, and any first included angle is equal.

[0135] In the aforementioned light panel, in light group 2, the angle between the top surfaces of two adjacent first lamp beads 201 along the circumferential direction is the first angle. The angles of any first angle in the light group are equal, which can ensure that the light output brightness around the light output zone B is uniform and ensure the light output effect of the light panel.

[0136] For example, such as Figure 4 Each lamp group 2 includes four first lamp beads 201. The light-emitting top surfaces D of the four first lamp beads 201 have different orientations, and the included angle between the light-emitting top surfaces D of two adjacent first lamp beads 201 can be 90 degrees.

[0137] Figures 7 to 9 , Figures 14 to 15 In the lamp group 2, the light-emitting top surface D of the multiple first lamp beads 201 have different orientations, which can ensure that the light-emitting brightness around the light-emitting zone B is uniform and ensure the light-emitting effect of the lamp board.

[0138] In some embodiments of this application, the lamp bead 21 may further include a light diffusion section, which may be disposed on the light-emitting top surface D of the lamp bead, so that the light emission from the light-emitting top surface D of the lamp bead 21 is more uniform, thereby ensuring that the light emission from the light-emitting zone B is more uniform and optimizing the light emission effect of the lamp board.

[0139] Specifically, the light diffusion section can be formed using a dispensing process.

[0140] In some embodiments of this application, the shape design of the above-mentioned lamp bead 21 can be as follows: Figure 15 and Figure 16 As shown.

[0141] like Figure 15 As shown, the light-emitting top surface D of the lamp bead is a quadrilateral. One set of opposite corners of the light-emitting top surface D is at a different distance from the base, while the other set of opposite corners is at the same distance from the base.

[0142] like Figure 16As shown, the light-emitting top surface of the lamp bead 21 is quadrilateral, and a set of opposite sides of the light-emitting top surface D are parallel to the substrate, and the two sides are at different distances from the substrate.

[0143] Specifically, the shape of the LED beads is not limited here and can be determined according to the actual situation.

[0144] Specifically, the shapes of the individual LED beads in the above-mentioned light group can be the same or different; there are no restrictions here, and it depends on the actual situation.

[0145] This application also provides a display device, including any of the lamp panels provided in the above-described technical solutions.

[0146] Specifically, the display device may include a backlight module and a liquid crystal display panel located on the light-emitting side of the backlight module. The backlight module may include any of the lamp boards provided in the above technical solutions.

[0147] The backlight module may include a back panel, a lamp panel, a light guide plate, and optical films.

[0148] The back panel may include a bottom panel and multiple side panels, which together with the bottom panel form an accommodating space.

[0149] The light panel is located within the accommodating space and is mounted on the base plate;

[0150] The light guide plate is located on the side of the lamp panel away from the base plate;

[0151] The optical film is placed on the side of the light guide plate away from the lamp plate.

[0152] In the aforementioned backlight module, the lamp groups on the lamp board are arranged in sections, and the top surface of the first lamp in the lamp group is designed with an angle, which can realize a large light emission angle design for each light emission section on the lamp board.

[0153] While ensuring the light output effect of the backlight module, compared with related technologies, the number of LEDs 21 used in each light output zone B on the light board can be reduced, which can further reduce the complexity of the wiring on the substrate, thereby reducing the cost of LEDs 21 on the light board and the manufacturing cost of the substrate, thus reducing the overall manufacturing cost of the light board.

[0154] The liquid crystal display panel may include an array substrate, a counter substrate, and a liquid crystal layer located between the array substrate and the counter substrate.

[0155] The aforementioned liquid crystal display panel does not include a color filter layer, which can increase the transmittance of the liquid crystal display panel, thereby improving the image quality of the display device while effectively and significantly reducing the power consumption of the liquid crystal display panel.

[0156] Specifically, the backlight module can be a multi-color backlight module. The display device can be a field-sequence display device.

[0157] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this application without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
