Description

Technical Field

[0001] Embodiments of this application relate to the technical field of backlighting, and more particularly to a lamp panel and a display device. Background Technology

[0002] Display devices typically include display modules, which are capable of displaying image information. A display module may include a backlight panel and an optical film layer; the backlight panel serves as the light source for the display module, and the optical film layer is disposed on one side of the backlight panel.

[0003] Typically, display modules are at high risk of developing shadows, which affects their display performance. Utility Model Content

[0004] The embodiments of this application provide a light panel and a display device that can reduce the risk of shadows appearing in the display module and improve the display performance of the display module.

[0005] On one hand, embodiments of this application provide a light panel. The light panel includes a substrate, a light-emitting group, a driving chip, a power supply wiring group, and a first bridging structure. The light-emitting group is disposed on the substrate and includes multiple light-emitting units. The multiple light-emitting units are arranged in multiple rows along a first direction and in multiple columns along a second direction, with the first and second directions perpendicular to each other. The driving chip is disposed on the substrate and connected to the light-emitting units, and the driving chip is used to drive the light-emitting units to emit light. The power supply wiring group is disposed on the substrate. The first bridging structure is disposed on the substrate, and the light-emitting units are connected to the power supply wiring group through the first bridging structure. The light-emitting unit includes multiple light-emitting chips, and at least two of the multiple light-emitting chips emit light of different colors. One of the driving chip and the first bridging structure is located between two adjacent rows of light-emitting units along the first direction and between two adjacent columns of light-emitting units along the second direction, while the other is located outside the arrangement range of the multiple light-emitting units on the substrate.

[0006] In the embodiments of this application, one of the driver chip and the first bridging structure is located between two adjacent columns of light-emitting units along the first direction and between two adjacent rows of light-emitting units along the second direction, while the other is located outside the arrangement range of multiple light-emitting units on the substrate, so that at least one light-emitting unit can be spaced between the driver chip and the first bridging structure, thereby increasing the distance between the driver chip and the first bridging structure.

[0007] In this way, the part of the optical film layer lifted by the driving chip and the part of the optical film layer lifted by the first bridging structure are not connected. Compared with the driving chip and the first bridging structure being set adjacent to each other, the area of ​​the optical film layer being lifted can be reduced, that is, the area of ​​the optical film layer protruding away from the substrate can be reduced, thereby reducing the risk of shadows appearing in the display module and improving the display performance of the display module.

[0008] Furthermore, by positioning one of the driver chip and the first bridging structure between two adjacent columns of light-emitting units along the first direction and between two adjacent rows of light-emitting units along the second direction, the driver chip and the first bridging structure do not need to occupy the wiring space between multiple light-emitting groups and between the edges of the light-emitting groups and the substrate. This allows for more space to be used for power supply wiring groups, enabling the width of the power supply wiring groups to be made larger, thereby reducing the voltage drop of the power supply wirings.

[0009] In some possible implementations, when the first bridging structure is disposed outside the arrangement range of the multiple light-emitting units on the substrate, the first bridging structure is disposed on one side of the multiple light-emitting units along a first direction.

[0010] This configuration allows the first bridging structure to be positioned between two adjacent light-emitting groups along the first direction, enabling the light-emitting units in two adjacent light-emitting groups along the first direction to be connected through the same first bridging structure and power supply wiring group, thus improving the ease of connection between the light-emitting units and the first bridging structure.

[0011] In some possible implementations, there are multiple light-emitting groups, arranged along a first direction and a second direction. Along the first direction, a driver chip is positioned between the multiple rows of light-emitting units, dividing them into a first group and a second group. In two adjacent light-emitting groups arranged along the first direction, the first group of light-emitting units in one group and the second group of light-emitting units in the other group are adjacent. A first bridging structure is positioned between the first group of light-emitting units in one group and the second group of light-emitting units in the other group. The first group of light-emitting units in one group and the second group of light-emitting units in the other group are connected through the same first bridging structure and power supply trace group.

[0012] This configuration allows the light-emitting units in two adjacent light-emitting groups along the first direction to connect to the first bridging structure nearby, shortening the wiring distance between the light-emitting units and the first bridging structure and improving the ease of connection between the light-emitting units and the first bridging structure.

[0013] In some possible implementations, the substrate includes a first edge and a second edge, configured as two edges of the substrate disposed opposite each other along a first direction. In adjacent light-emitting groups along the first direction and the second edge, a first group of light-emitting units is closer to the second edge than a second group of light-emitting units. The lamp board also includes a second bridging structure disposed on the substrate and located between two adjacent light-emitting groups along a second direction. In two adjacent light-emitting groups along the second direction, the first group of light-emitting units in one light-emitting group is connected to a power supply trace group via the second bridging structure, and the first group of light-emitting units in the other light-emitting group is connected to a power supply trace group via the second bridging structure.

[0014] In this way, the light-emitting units in two adjacent light-emitting groups arranged along the second direction can be connected to the second bridging structure nearby, which shortens the wiring distance between the light-emitting units and the second bridging structure and improves the connection convenience between the light-emitting units and the second bridging structure.

[0015] In some possible implementations, when the first bridging structure is located outside the arrangement range of the multiple light-emitting units on the substrate, the first bridging structure is located on one side of the multiple light-emitting units along the second direction.

[0016] This configuration allows the first bridging structure to be positioned between two adjacent light-emitting groups along the second direction, enabling the light-emitting units in two adjacent light-emitting groups along the second direction to be connected through the same first bridging structure and power supply wiring group, thus improving the ease of connection between the light-emitting units and the first bridging structure.

[0017] In some possible implementations, multiple light-emitting units in a light-emitting group are connected by one or at least two first bridging structures and power supply wiring groups.

[0018] This configuration improves the connection flexibility between multiple light-emitting units in a light-emitting group and the first bridging structure, meeting the needs of different situations.

[0019] In some possible implementations, when multiple light-emitting units in a light-emitting group are connected through at least two first bridging structures and power supply traces, the at least two first bridging structures connected to the multiple light-emitting units in the light-emitting group are spaced apart along a first direction or a second direction.

[0020] This configuration improves the flexibility of the setup of at least two first bridging structures connected to multiple light-emitting units in a light-emitting group, meeting the needs of different situations.

[0021] In some possible implementations, at least two of the multiple light-emitting units are connected in series. Of the at least two light-emitting units connected in series, one light-emitting unit is connected to the driver chip, and the other light-emitting unit is connected to the power supply wiring group. The at least two light-emitting units connected in series are spaced apart along a first direction or a second direction.

[0022] By connecting at least two of the multiple light-emitting units in series with the driver chip and power supply wiring group, it is possible to achieve zoned control of multiple light-emitting units in the light-emitting group. Compared with connecting multiple light-emitting units separately with the driver chip and power supply wiring group, it can simplify the wiring structure of the substrate, reduce the number of driver chips, and help reduce the cost of the lamp board.

[0023] At least two light-emitting units connected in series are spaced apart along a first direction or a second direction, which can improve the flexibility of the light-emitting units on the substrate and meet different needs.

[0024] In some possible implementations, at least two light-emitting units connected in series form a lamp zone, and the number of lamp zones is multiple. When the at least two light-emitting units connected in series are spaced apart along a first direction, the multiple lamp zones are spaced apart along a first direction and a second direction, or the multiple lamp zones are spaced apart along a second direction. When the at least two light-emitting units connected in series are spaced apart along a second direction, the multiple lamp zones are spaced apart along a first direction and a second direction, or the multiple lamp zones are spaced apart along a first direction.

[0025] This configuration allows multiple light zones to be arranged on substrates of different sizes and shapes, and enables the light-emitting units in multiple light-emitting groups to be arranged in an odd number of columns or rows on the substrate, thus meeting the arrangement requirements of the substrate under different conditions.

[0026] On the other hand, embodiments of this application provide a display device. The display device includes a backlight module and a liquid crystal panel. The backlight module includes a lamp panel and an optical film layer, the optical film layer being disposed on the light-emitting side of the lamp panel. The liquid crystal panel is disposed on the side of the optical film layer away from the lamp panel.

[0027] The display device provided in the embodiments of this application includes the lamp panel as described above, and therefore has all the above-described beneficial effects, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 a part of the embodiments of this application, and not all possible 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.

[0039] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0040] As used herein, terms such as “equal,” “parallel,” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equal items less than or equal to 5% of either one.

[0041] In the embodiments of this application, the directional indications used to explain the structure and movement of different components, such as up, down, left, right, front, and back, are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.

[0042] Figure 1 This is a schematic diagram of the structure of a display device provided in some embodiments of this application. For example... Figure 1 As shown, an embodiment of this application provides a display device 200, which has an image display function.

[0043] The display device 200 can be a television, laptop computer, tablet computer, in-vehicle computer, smartphone, smartwatch, projection device, head-up display (HDU), augmented reality (AR) glasses, etc. The embodiments of this application do not further limit the specific form of the display device 200.

[0044] like Figure 1As shown, the display device 200 may include a display module 210 and a housing 220. The display module 210 is used to display image information. The display module 210 may be a light-emitting diode (LED) display module. For example, the display module 210 may be at least one of a micro light-emitting diode (Micro LED) display module and a mini light-emitting diode (Mini LED) display module.

[0045] Understandably, Mini LED display modules and Micro LED display modules have advantages such as self-illumination, high brightness, high contrast, high resolution, high color saturation, long lifespan, fast response speed, and low power consumption.

[0046] The display module 210 includes a light-emitting side and a backlight side disposed opposite to each other. A housing 220 is disposed on the backlight side and connected to the display module 210, thereby protecting the display module 210 and reducing the impact of the housing 220 on the light emitting side of the display module 210. For example, the housing 220 can be connected to the display module 210 by a snap-fit ​​connection, or it can be connected to the display module 210 by an adhesive connection; the embodiments of this application do not further limit this.

[0047] like Figure 1 As shown, the display device 200 may also include a bracket 230, which is disposed on one side of the housing 220 and connected to the housing 220, serving to support the housing 220 and the display module 210.

[0048] Figure 2 This is a schematic diagram illustrating the structure of a display module provided in some embodiments of this application. In some examples, such as... Figure 2 As shown, the display module 210 includes a backlight module 211 and a liquid crystal panel 212. That is, the display device 200 includes a backlight module 211 and a liquid crystal panel 212.

[0049] The backlight module 211 includes a lamp panel 100 and an optical film layer 2111. Understandably, the lamp panel 100 is the light source of the display module 210, and the light-emitting side of the lamp panel 100 is the light-emitting side of the display module 210.

[0050] The optical film layer 2111 is disposed on the light-emitting side of the lamp panel 100. The light emitted by the lamp panel 100 can pass through the optical film layer 2111, and the optical film layer 2111 can perform optical processing on the light emitted by the lamp panel 100.

[0051] For example, the number of optical film layers 2111 can be one or more. When the number of optical film layers 2111 is multiple, the multiple optical film layers 2111 can be stacked on the light-emitting side of the lamp panel 100.

[0052] The optical film layer 2111 may include at least one of a light-diffusing sheet, a prism sheet, and a diffuser sheet. Understandably, the light-diffusing sheet is used to homogenize light, the prism sheet is used to refract or reflect light to improve the brightness of the display module 210, and the diffuser sheet is used to diffuse light. Understandably, the optical film layer 2111 may also include other light-processing films besides the light-diffusing sheet, prism sheet, and diffuser sheet; the embodiments of this application do not further limit the specific form of the optical film layer 2111.

[0053] Continue to refer to Figure 2 In some examples, the liquid crystal panel 212 is disposed on the side of the optical film layer 2111 away from the lamp panel 100. For example, the liquid crystal panel 212 may include a stacked liquid crystal driving circuit (not shown) and a liquid crystal layer, the liquid crystal layer including a plurality of liquid crystal molecules 212a, the liquid crystal driving circuit being able to apply a voltage to the liquid crystal molecules 212a, causing the liquid crystal molecules 212a to deflect, so as to transmit or block the light emitted by the backlight module 211.

[0054] The display module 210 may further include a color filter 213, which is disposed on the side of the liquid crystal panel 212 away from the backlight module 211. The color filter 213 has red, green, and blue pixel blocks. The red pixel blocks transmit red light, the green pixel blocks transmit green light, and the blue pixel blocks transmit blue light. The size and shape of the red, green, and blue pixel blocks may be the same or different. The embodiments of this application do not further limit the size, shape, or arrangement of the red, green, and blue pixel blocks.

[0055] Understandably, the light passing through the color filter 213 is red, green and blue light of different intensities, enabling the display module 210 to achieve full-color display.

[0056] The embodiments of this application do not further limit the liquid crystal panel 212 and color filter 213, etc., and the lamp board 100 is described by example below.

[0057] Figure 3 This is a schematic diagram of the structure of a lamp panel provided in some embodiments of this application. Figure 4 This is a schematic diagram of the structure of a lamp panel provided in some other embodiments of this application. Figure 5 for Figure 3 A magnified schematic diagram of the Q11 region. Figure 6 for Figure 4 A magnified schematic diagram of the Q21 region.

[0058] In some examples, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the lamp panel 100 may include a substrate 110 and a light-emitting group 120, the light-emitting group 120 being disposed on the substrate 110. The light-emitting group 120 includes a plurality of light-emitting units 121.

[0059] For example, substrate 110 can be a single-layer aluminum substrate, or substrate 110 can be a multilayer printed circuit board (PCB). The embodiments of this application use a single-layer aluminum substrate as an example for further illustration.

[0060] Understandably, the light-emitting group 120 is capable of emitting light. The light-emitting group 120 may include eight light-emitting units 121, or the light-emitting group 120 may also include other numbers of light-emitting units 121. The embodiments of this application do not further limit the number of light-emitting units 121 in the light-emitting group 120.

[0061] Figure 7 The diagram illustrates the structure of the light-emitting unit and the conductive unit provided in some embodiments of this application. In some examples, such as... Figure 7 As shown, the light-emitting unit 121 includes a plurality of light-emitting chips 1211, and at least two of the plurality of light-emitting chips 1211 emit light of different colors.

[0062] The light-emitting chip 1211 can be a miniLED chip. There can be three light-emitting chips 1211, which can be used to emit red, green, and blue light respectively. Alternatively, there can be two light-emitting chips 1211, which can be used to emit green and blue light respectively. Or, there can be four light-emitting chips 1211, with two emitting red light and the other two emitting green and blue light, or two emitting green light and the other two emitting red and blue light.

[0063] Multiple light-emitting chips 1211 can be spaced apart along a first direction X, or along a second direction Y, or along both directions X and Y. The first direction X and the second direction Y are perpendicular.

[0064] For example, the second direction Y and the first direction X can be perpendicular or approximately perpendicular. That is, the angle between the second direction Y and the first direction X can be 90°, or it can be 88° or 89°, etc.

[0065] The light-emitting unit 121 includes multiple light-emitting chips 1211, with at least two light-emitting chips 1211 emitting light of different colors, which can improve the color gamut of the display module 210 and facilitate image display.

[0066] For example, such as Figure 7 As shown, the substrate 110 may include a plurality of conductive connection units 181, the number of conductive connection units 181 being equal to the number of light-emitting units 121, and the plurality of conductive connection units 181 and the plurality of light-emitting units 121 being connected in a one-to-one correspondence.

[0067] The conductive connection unit 181 may include a plurality of conductive connection portions 1811. The number of conductive connection portions 1811 and the number of light-emitting chips 1211 may be equal. The plurality of conductive connection portions 1811 and the plurality of light-emitting chips 1211 are connected in a one-to-one correspondence, so that the plurality of light-emitting chips 1211 in the light-emitting unit 121 can be connected to the substrate 110 respectively.

[0068] Alternatively, the number of conductive connections 1811 may be less than the number of light-emitting chips 1211, and at least two light-emitting chips 1211 may be connected to the same conductive connection 1811. For example, at least two light-emitting chips 1211 with the same emitting color may be connected to the same conductive connection 1811.

[0069] For example, the conductive connection portion 1811 may include a first sub-portion 1811a and a second sub-portion 1811b, the anode pin of the light-emitting chip 1211 is connected to the first sub-portion 1811a, and the cathode pin of the light-emitting chip 1211 is connected to the second sub-portion 1811b.

[0070] Continue to refer to Figure 5 and Figure 6 In some examples, the lamp board 100 may include a driver chip 130 disposed on the substrate 110 and connected to the light-emitting unit 121, the driver chip 130 being used to drive the light-emitting unit 121 to emit light.

[0071] The driver chip 130 can be connected to multiple light-emitting chips 1211 in the light-emitting unit 121 respectively, so that the driver chip 130 can drive the light-emitting unit 121 to emit light.

[0072] Continue to refer to Figure 5 and Figure 6 In some examples, the lamp board 100 may include a power supply line group 141 and a first bridging structure 161, the power supply line group 141 being disposed on the substrate 110. The first bridging structure 161 is disposed on the substrate 110, and the light-emitting unit 121 is connected to the power supply line group 141 through the first bridging structure 161.

[0073] Understandably, the first bridging structure 161 enables cross-line connection. The substrate 110 is a single-layer aluminum substrate. By placing the first bridging structure 161 on the substrate, two intersecting traces on the substrate 110 can be connected through the first bridging structure 161.

[0074] The power supply voltage of the light-emitting chip 1211 that emits different colors of light is different. For example, the power supply voltage of the light-emitting chip 1211 that emits red light can be lower than the power supply voltage of the light-emitting chip 1211 that emits green light. The power supply voltage of the light-emitting chip 1211 that emits green light can be lower than the power supply voltage of the light-emitting chip 1211 that emits blue light.

[0075] The power supply wiring group 141 may include multiple power supply lines. Multiple light-emitting chips 1211 in the light-emitting unit 121 can be connected to the multiple power supply lines in the power supply wiring group 141 through the first bridging structure 161, so as to realize separate power supply for light-emitting chips 1211 with different light-emitting colors.

[0076] For example, the number of power traces in the power trace group 141 and the number of light-emitting chips 1211 in the light-emitting unit 121 can be equal, and the multiple power traces in the power trace group 141 and the multiple light-emitting chips 1211 in the light-emitting unit 121 are connected in a one-to-one correspondence.

[0077] The number of power traces in the power trace group 141 can also be less than the number of light-emitting chips 1211 in the light-emitting unit 121, with at least two light-emitting chips 1211 connected to the same power trace in the power trace group 141. For example, at least two light-emitting chips 1211 with the same light emission color can be connected to the power supply circuit 101 through the same power trace in the power trace group 141.

[0078] When the number of power lines in the power line group 141 is less than the number of light-emitting chips 1211 in the light-emitting unit 121, the blue light-emitting chip 1211 and the green light-emitting chip 1211 can also be connected to the power supply circuit 101 through the same power line in the power line group 141.

[0079] For example, the lamp board 100 may include terminal blocks disposed on the substrate 110. Power traces in the power trace assembly 141 may be connected to the terminal blocks and, through the terminal blocks, to the power supply circuit (see...). Figure 8 )connect.

[0080] The terminal block may include a body and multiple wiring pins. The multiple wiring pins may be arranged on both sides of the body along a first direction X and spaced apart along a second direction Y to improve the connection convenience between the power lines and the terminal blocks in the power line assembly 141.

[0081] For example, such as Figure 6 As shown, the lamp board 100 may also include a grounding trace 151, which is disposed on the substrate 110 and connected to the driver chip 130 to ground the driver chip 130.

[0082] Figure 8 The following is a structural block diagram of a display device provided in some embodiments of this application. Referring below... Figure 8 An example is given of a method for displaying images on the display device 200.

[0083] like Figure 8 As shown, the display device 200 may include a motherboard 201, a central control board 202, and a driver board 203. The motherboard 201, the central control board 202, and the driver board 203 are respectively disposed within the receiving space enclosed by the housing 220.

[0084] The motherboard 201, the central control board 202, and the driver board 203 may include at least one of a printed circuit board (PCB), a flexible printed circuit board (FPC), and a flexible printed circuit board (FPCB). The specific forms of the motherboard 201, the central control board 202, and the driver board 203 may be the same or different, and the embodiments of this application do not further limit them.

[0085] The display module 210 may also include a main chip 204, a backlight control chip (bcon chip) 205, and a timing control chip (tcon chip) 206. The main chip 204 is located on the motherboard 201, the backlight control chip 205 is located on the central control board 202, and the timing control chip 206 is located on the driver board 203.

[0086] Alternatively, the display device 200 may consist of only the motherboard 201, with the main chip 204, backlight control chip 205, and timing control chip 206 all located on the motherboard 201.

[0087] The embodiments of this application take the example of a display device 200 including a motherboard 201, a central control board 202, and a driver board 203, and will be further illustrated below.

[0088] Continue to refer to Figure 8 The motherboard 201 is connected to the central control board 202 and the driver board 203 respectively, so that the main chip 204 can transmit signals to the backlight control chip 205 and the timing control chip 206 respectively.

[0089] For example, the main chip 204 can receive video sources from external sources and decode the video sources. After decoding the video sources, the main chip 204 can send a portion of the data to the backlight control chip 205 and another portion of the data to the timing control chip 206.

[0090] The timing control chip 206 can be connected to the liquid crystal driving circuit of the liquid crystal panel 212, so that the timing control chip 206 can control the deflection of the liquid crystal molecules 212a.

[0091] The backlight control chip 205 can be connected to the driver chip 130, and the driver chip 130 is connected to the light-emitting unit 121, so that the backlight control chip 205 can control the light-emitting unit 121 to emit light through the driver chip 130.

[0092] The display module 210 may also include a power supply circuit 101, which is connected to the power supply wiring group 141 through a terminal block, so that the power supply circuit 101 can be connected to the light-emitting unit 121 and thus supply power to the light-emitting unit 121.

[0093] The driver chip 130 can receive the light emission state of the light-emitting unit 121 and generate a first feedback signal based on the light emission state of the light-emitting unit 121, and feed the first feedback signal back to the backlight control chip 205. The backlight control chip 205 can generate a second feedback signal based on the first feedback signal and feed the second feedback signal back to the power supply circuit 101. The power supply circuit 101 can supply power to the light-emitting unit 121 based on the second feedback signal to achieve closed-loop control.

[0094] Understandably, in order to simplify the structure of the attached figures, Figure 8 Only one light-emitting chip 1211 in the light-emitting unit 121 is shown, and the number of light-emitting chips 1211 in the light-emitting unit 121 is not limited. Furthermore, to simplify the structure of the drawings, Figure 8 Only one power trace connecting the light-emitting unit 121 and the power supply circuit 101 is shown in the diagram, and the number of power traces in the power trace group 141 is not limited.

[0095] In some possible cases, multiple light-emitting units 121 are spaced apart along a first direction X, and a driving chip 130 and a first bridging structure 161 are disposed on one side of the multiple light-emitting units 121 along a second direction Y.

[0096] For example, the first direction X can be the length direction of the substrate 110, and the second direction Y can be the width direction of the substrate 110.

[0097] For example, along the first direction X, the driver chip 130 and the first bridging structure 161 are typically positioned close to the middle of the plurality of light-emitting units 121 to improve the ease of connection between the driver chip 130 and the first bridging structure 161 and the light-emitting units 121.

[0098] However, the height of both the driver chip 130 and the first bridging structure 161 is relatively large, which allows the driver chip 130 and the first bridging structure 161 to lift up a portion of the optical film layer 2111, that is, to make a portion of the optical film layer 2111 bulge away from the substrate 110.

[0099] The driving chip 130 and the first bridging structure 161 are positioned close to the middle of the plurality of light-emitting units 121 in the first direction X, which causes the portion of the optical film layer 2111 lifted by the driving chip 130 and the portion of the optical film layer 2111 lifted by the first bridging structure 161 to be connected, resulting in a larger area of ​​the area where the optical film layer 2111 is lifted, that is, a larger area of ​​the area where the optical film layer 2111 protrudes in the direction away from the substrate 110.

[0100] When the area of ​​the protruding region of the optical film layer 2111 in the direction away from the substrate 110 is large, a shadow will appear on the display module 210, affecting the display performance of the display module 210.

[0101] Based on this, in the embodiments of this application, such as Figure 5 and Figure 6 As shown, multiple light-emitting units 121 are arranged in multiple rows along the first direction X and in multiple columns along the second direction Y.

[0102] For example, multiple light-emitting units 121 can be arranged in 4 rows along the first direction X and in 2 columns along the second direction Y. Alternatively, multiple light-emitting units 121 can be arranged in other numbers of rows along the first direction X and in other numbers of columns along the second direction Y. The embodiments of this application do not further limit the values ​​of the number of rows arranged along the first direction X and the number of columns arranged along the second direction Y of multiple light-emitting units 121.

[0103] like Figure 5 and Figure 6 As shown, one of the driving chip 130 and the first bridging structure 161 is located between two adjacent rows of light-emitting units 121 along the first direction X and between two adjacent columns of light-emitting units 121 along the second direction Y, while the other is located outside the arrangement range of the multiple light-emitting units 121 on the substrate 110.

[0104] Understandably, the arrangement range of the multiple light-emitting units 121 on the substrate 110 is the range of the closed pattern enclosed by the outer contours of the multiple light-emitting units 121 on the substrate 110.

[0105] For example, the chip 130 can be positioned between two adjacent rows of light-emitting units 121 along the first direction X, and between two adjacent columns of light-emitting units 121 along the second direction Y, with the first bridging structure 161 positioned outside the arrangement range of the plurality of light-emitting units 121 on the substrate 110.

[0106] Alternatively, the first bridging structure 161 can be located between two adjacent rows of light-emitting units 121 along the first direction X, and between two adjacent columns of light-emitting units 121 along the second direction Y, with the driving chip 130 located outside the arrangement range of the multiple light-emitting units 121 on the substrate 110.

[0107] In the embodiments of this application, one of the driving chip 130 and the first bridging structure 161 is located between two adjacent rows of light-emitting units 121 along the first direction X and between two adjacent columns of light-emitting units 121 along the second direction Y. The other is located outside the arrangement range of the multiple light-emitting units 121 on the substrate 110, so that at least one light-emitting unit 121 can be spaced between the driving chip 130 and the first bridging structure 161, thereby increasing the distance between the driving chip 130 and the first bridging structure 161.

[0108] In this way, the portion of the optical film layer 2111 lifted by the driving chip 130 and the portion of the optical film layer 2111 lifted by the first bridging structure 161 are not connected. Compared with the driving chip 130 and the first bridging structure 161 being arranged adjacently, the area of ​​the area where the optical film layer 2111 is lifted can be reduced, that is, the area of ​​the area where the optical film layer 2111 protrudes in the direction away from the substrate 110 can be reduced, thereby reducing the risk of shadows appearing in the display module 210 and improving the display performance of the display module 210.

[0109] Furthermore, one of the driver chip 130 and the first bridging structure 161 is located between two adjacent rows of light-emitting units 121 along the first direction X, and between two adjacent columns of light-emitting units 121 along the second direction Y. This means that one of the driver chip 130 and the first bridging structure 161 does not need to occupy the wiring space between multiple light-emitting groups 120 and between the edges of the light-emitting groups 120 and the substrate 110. This allows the width of the power traces in the power trace group 141 to be made larger, thereby reducing the voltage drop of the power traces.

[0110] In some examples, such as Figure 5 and Figure 6 As shown, when the first bridging structure 161 is disposed outside the arrangement range of the plurality of light-emitting units 121 on the substrate 110, the first bridging structure 161 is disposed on one side of the plurality of light-emitting units 121 along the first direction X.

[0111] This configuration allows the first bridging structure 161 to be positioned between two adjacent light-emitting groups 120 along the first direction X, thereby enabling the light-emitting units 121 in the two adjacent light-emitting groups 120 along the first direction X to be connected to the power supply wiring group 141 through the same first bridging structure 161, which improves the ease of connection between the light-emitting units 121 and the first bridging structure 161.

[0112] Continue to refer to Figure 5 and Figure 6 In some examples, there are multiple light-emitting groups 120, which are arranged along the first direction X and the second direction Y. For example, the multiple light-emitting groups 120 can be arranged in an array along the first direction X and the second direction Y, or the multiple light-emitting groups 120 can be arranged along the first direction X and the second direction Y in other ways. The embodiments of this application do not further limit this.

[0113] Understandably, the light-emitting units 121 in the plurality of light-emitting groups 120 arranged adjacent to each other along the second direction Y are respectively connected to the power supply line group 141.

[0114] like Figure 5 As shown, along the first direction X, the driving chip 130 is disposed between the multiple rows of light-emitting units 121, and divides the multiple rows of light-emitting units 121 into a first group of light-emitting units 121a and a second group of light-emitting units 121b.

[0115] The first group of light-emitting units 121a and the second group of light-emitting units 121b are arranged at intervals along the first direction X. The number of rows of light-emitting units 121 in the first group of light-emitting units 121a and the number of rows of light-emitting units 121 in the second group of light-emitting units 121b can be the same or different.

[0116] Understandably, when the number of rows of light-emitting units 121 in the first group of light-emitting units 121a is the same as the number of rows of light-emitting units 121 in the second group of light-emitting units 121b, the driving chip 130 is positioned in the middle of the multiple rows of light-emitting units 121 along the first direction X, which can improve the ease of connection between the driving chip 130 and the light-emitting units 121 in the first group of light-emitting units 121a and the light-emitting units 121 in the second group of light-emitting units 121b.

[0117] Continue to refer to Figure 5In two adjacent light-emitting groups 120 arranged along the first direction X, the first group of light-emitting units 121a of one light-emitting group 120 and the second group of light-emitting units 121b of the other light-emitting group 120 are adjacent. The first bridging structure 161 is disposed between the first group of light-emitting units 121a of one light-emitting group 120 and the second group of light-emitting units 121b of the other light-emitting group 120. The first group of light-emitting units 121a of one light-emitting group 120 and the second group of light-emitting units 121b of the other light-emitting group 120 are connected to the power supply line group 141 through the same first bridging structure 161.

[0118] This configuration allows the light-emitting units 121 in two adjacent light-emitting groups 120 arranged along the first direction X to be connected to the first bridging structure 161 nearby, shortening the wiring distance between the light-emitting units 121 and the first bridging structure 161 and improving the ease of connection between the light-emitting units 121 and the first bridging structure 161.

[0119] In some examples, such as Figure 3 and Figure 4 As shown, the substrate 110 includes a first edge L1 and a second edge L2, which are configured as two edges of the substrate 110 disposed opposite to each other along a first direction X.

[0120] For example, the substrate 110 can be a rectangular or approximately rectangular structure, such that the first edge L1 and the second edge L2 can be positioned opposite each other along the first direction X.

[0121] Continue to refer to Figure 5 In the adjacent light-emitting groups 120 along the first direction X and the second edge L2, the first group of light-emitting units 121a is closer to the second edge L2 than the second group of light-emitting units 121b. The lamp board 100 also includes a second bridging structure 162, which is disposed on the substrate 110 and located between two adjacent light-emitting groups 120 along the second direction Y.

[0122] In two adjacent light-emitting groups 120 arranged along the second direction Y, the first group of light-emitting units 121a in one light-emitting group 120 is connected to the power supply line group 141 through the second bridging structure 162, and the first group of light-emitting units 121a in the other light-emitting group 120 is connected to the power supply line group 141 through the second bridging structure 162.

[0123] In this way, the light-emitting units 121 in two adjacent light-emitting groups 120 arranged along the second direction Y can be connected to the second bridging structure 162 nearby, which shortens the distance of the wiring between the light-emitting units 121 and the second bridging structure 162 and improves the connection convenience between the light-emitting units 121 and the second bridging structure 162.

[0124] In some examples, such as Figure 6 As shown, when the first bridging structure 161 is disposed outside the arrangement range of the plurality of light-emitting units 121 on the substrate 110, the first bridging structure 161 is disposed on one side of the plurality of light-emitting units 121 along the second direction Y.

[0125] This configuration allows the first bridging structure 161 to be positioned between two adjacent light-emitting groups 120 along the second direction Y. This enables the light-emitting units 121 in the two adjacent light-emitting groups 120 along the second direction Y to be connected to the power supply wiring group 141 through the same first bridging structure 161, thereby improving the ease of connection between the light-emitting units 121 and the first bridging structure 161.

[0126] In some examples, such as Figure 6 As shown, a plurality of light-emitting units 121 in a light-emitting group 120 are connected by one or more first bridging structures 161 and power supply wiring groups 141.

[0127] This configuration improves the connection flexibility between multiple light-emitting units 121 in a light-emitting group 120 and the first bridging structure 161, meeting the needs under different circumstances.

[0128] In some examples, such as Figure 6 As shown, when multiple light-emitting units 121 in a light-emitting group 120 are connected through at least two first bridging structures 161 and power supply wiring groups 141, the at least two first bridging structures 161 connected to the multiple light-emitting units 121 in a light-emitting group 120 are spaced apart along the first direction X or the second direction Y.

[0129] This configuration improves the flexibility of the configuration of at least two first bridging structures 161 connected to multiple light-emitting units 121 in a light-emitting group 120, meeting the needs of different situations.

[0130] In some examples, such as Figure 5 and Figure 6 As shown, at least two of the multiple light-emitting units 121 are connected in series. Among the at least two light-emitting units 121 connected in series, one light-emitting unit 121 is connected to the driver chip 130, and the other light-emitting unit 121 is connected to the power supply wiring group 141. The at least two light-emitting units 121 connected in series are spaced apart along the first direction X or the second direction Y.

[0131] Understandably, multiple light-emitting chips 1211 in one light-emitting unit 121 are connected to the driver chip 130 respectively, and multiple light-emitting chips 1211 in another light-emitting unit 121 are connected to multiple power lines in the power line group 141 through a bridging structure (e.g., the first bridging structure 161 or the second bridging structure 162).

[0132] At least two light-emitting units 121 connected in series can be spaced apart along the first direction X (see [reference]). Figure 5 Alternatively, at least two light-emitting units 121 connected in series can also be spaced apart along the second direction Y (see...). Figure 6 ).

[0133] By connecting at least two of the multiple light-emitting units 121 in series with the driver chip 130 and the power supply wiring group 141, it is possible to achieve zoned control of the multiple light-emitting units 121 in the light-emitting group 120. Compared with connecting the multiple light-emitting units 121 to the driver chip 130 and the power supply wiring group 141 respectively, the wiring structure of the substrate 110 can be simplified, the number of driver chips 130 can be reduced, and the cost of the lamp board 100 can be reduced.

[0134] At least two light-emitting units 121 connected in series are arranged at intervals along the first direction X or the second direction Y, which can improve the flexibility of the arrangement of the light-emitting units 121 on the substrate 110 and meet different needs.

[0135] Continue to refer to Figure 5 In some examples, at least two light-emitting units 121 connected in series form a light area P. It can be understood that in the embodiments of this application, the light area P is a light-emitting area formed by connecting at least two light-emitting units 121 in series.

[0136] There are multiple light zones P. When at least two light-emitting units 121 connected in series are spaced apart along the first direction X, multiple light zones P are spaced apart along the first direction X and the second direction Y, or multiple light zones P are spaced apart along the second direction Y.

[0137] When multiple light zones P are spaced apart along the first direction X and the second direction Y, the multiple light zones P can be arranged in an array along the first direction X and the second direction Y, or the multiple light zones P can be arranged in an L-shape or approximately L-shape along the first direction X and the second direction Y.

[0138] Understandably, multiple lamp areas P can be spaced apart along the first direction X and the second direction Y, or multiple lamp areas P can be spaced apart along the second direction Y, so that multiple lamp areas P can be arranged on substrates 110 of different sizes and shapes, and so that the light-emitting units 121 in multiple light-emitting groups 120 can be arranged in odd number of columns or odd number of rows on substrates 110, satisfying the arrangement requirements of substrates 110 under different conditions.

[0139] like Figure 6 As shown, when at least two light-emitting units 121 connected in series are spaced apart along the second direction Y, multiple light areas are spaced apart along the first direction X and the second direction Y, or multiple light areas P are spaced apart along the first direction X.

[0140] When multiple light zones P are spaced apart along the first direction X and the second direction Y, the multiple light zones P can be arranged in an array along the first direction X and the second direction Y, or the multiple light zones P can be arranged in an L-shape or approximately L-shape along the first direction X and the second direction Y.

[0141] Understandably, multiple lamp areas P can be spaced apart along the first direction X and the second direction Y, or multiple lamp areas P can be spaced apart along the first direction X, so that multiple lamp areas P can be arranged on substrates 110 of different sizes and shapes, and so that the light-emitting units 121 in multiple light-emitting groups 120 can be arranged in odd columns or odd rows on substrates 110, satisfying the arrangement requirements of substrates 110 under different conditions.

[0142] Understandably, in different light-emitting groups 120, the arrangement of multiple light zones P can be the same or different.

[0143] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or as many of the technical features as possible; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
