Technical Field

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

[0002] As people's demands for home audio-visual entertainment experiences continue to increase, they are placing higher demands on the clarity, color, and realism of images on display devices such as televisions.

[0003] Display devices typically include an LCD panel, a backlight module for emitting light, and a processor for controlling the backlight module and the LCD panel. The backlight module includes an optical film layer and a lamp board. The lamp board has multiple light-emitting units for emitting light, and multiple driver chips for driving the light-emitting units to emit light. The driver chips are connected to the processor through multiple wiring groups.

[0004] However, bridging structures are needed at the intersections of different wiring groups, and the increased number of bridging structures leads to higher costs for the lamp boards and display devices. Utility Model Content

[0005] This application discloses a light panel and a display device that can reduce the cost of the light panel and the display device.

[0006] To achieve the above objectives, in a first aspect, this application discloses a light panel, including a substrate, light-emitting units, driver chips, a first circuit group, and a second circuit group. The substrate is provided with terminals for connecting to a processor. Multiple light-emitting units are disposed on the substrate, each having multiple light-emitting chips. These multiple light-emitting chips emit at least two different colors of light. Multiple driver chips are arranged in an array on the substrate. Each driver chip is connected to at least one light-emitting unit and is used to drive the corresponding light-emitting unit to emit light. The first circuit group is connected between the multiple driver chips, and the multiple driver chips are sequentially connected in series to the terminals via the first circuit group. The first circuit group is configured as address lines for the driver chips. The second circuit group is connected between the multiple driver chips, and the multiple driver chips are sequentially connected in series to the terminals via the second circuit group. The second circuit group is configured as data lines for the driver chips.

[0007] With the above configuration, the driver chips connected to the first line group and the driver chips connected to the second line group are all connected in series. The second line group can extend in the same or similar direction as the first line group. This can reduce or even avoid the crossing between the first line group and the second line group, thereby reducing or even avoiding the use of bridging structures and reducing the cost of the lamp board and display device.

[0008] Optionally, the substrate has a first side extending along a first direction and a second side extending along a second direction, with an included angle between the first and second directions. The first circuit group includes multiple first traces extending along the first direction and multiple second traces extending along the second direction. The first traces and second traces are alternately arranged and connected in sequence to connect multiple driver chips in series. The first traces are connected in series between some driver chips, and the second traces are connected between driver chips connected in series by different first traces. The driver chips connected in series by the first traces are spaced apart along the first direction.

[0009] With the above configuration, the first circuit group can connect multiple driver chips on the substrate in series to the terminal block.

[0010] Optionally, the driver chip includes a first driver chip and a second driver chip, which are respectively connected to the opposite ends of the first trace segment. The first driver chips of two adjacent first trace segments are interconnected, or the second driver chips of two adjacent first trace segments are interconnected.

[0011] With the above settings, the second wiring segment can connect multiple first wiring segments sequentially end to end to connect multiple driver chips on different first wirings in series, and can simplify the wiring of the first wiring group and reduce the production difficulty of the lamp board.

[0012] Optionally, at least two of the multiple first wiring segments are disposed on the side of the terminal block closest to the first side.

[0013] Optionally, the terminal block has an input port and an output port, and both the first line group and the second line group are connected in series between the input port and the output port.

[0014] Optionally, the first and second line groups are respectively connected to the same output port of the terminal block. This configuration saves on the number of terminal block output ports, reducing costs.

[0015] Optionally, the first line group and the second line group are connected to different output ports of the terminal block.

[0016] Optionally, in the transmission direction of the second line group, the driver chip located at the end of the second line group is connected to the input port of the terminal block through the first line group. This configuration saves on the input ports of the terminal block, reducing costs.

[0017] Optionally, it also includes a third line group, which is connected between multiple driver chips and configured to form the power lines of the driver chips, wherein the third line group connects multiple driver chips in series to the terminal block.

[0018] With the above configuration, the driver chips connected to the first, second, and third line groups are all connected in series. The first, second, and third line groups can all be routed in the same or similar directions, thereby reducing or even avoiding the crossing between the first, second, and third line groups, thus reducing or even avoiding the use of bridging structures, and thus reducing the cost of the lamp board and display device.

[0019] Optionally, the third circuit group connects multiple driver chips in parallel to the terminal block.

[0020] Optionally, the light-emitting unit includes a first light-emitting chip, a second light-emitting chip, and a third light-emitting chip, wherein the first light-emitting chip is used to emit red light, the second light-emitting chip is used to emit blue light, and the third light-emitting chip is used to emit green light.

[0042] As mentioned in the background section, with the increasing demands for home entertainment experiences, higher requirements are being placed on the image clarity, color, and realism of display devices such as televisions. Display devices typically consist of an LCD panel, a backlight module for emitting light, and a processor that controls the backlight module and the LCD panel. The backlight module includes an optical film layer and a lamp board. The lamp board has multiple light-emitting units and multiple driver chips for driving these units. These driver chips are connected to the processor via multiple wiring groups. However, bridging structures are needed at the intersections of different wiring groups, and the increased number of bridging structures leads to higher costs for both the lamp board and the display device.

[0043] To address the aforementioned issues, this application provides a light panel to resolve the problem of increased costs for both the light panel and the display device due to the numerous bridging structures present in related technologies.

[0044] Please refer to Figures 1 to 6 The lamp board 12 of this application includes: a substrate 100, a light-emitting unit 300, a driver chip 400, a first circuit group 500, and a second circuit group 600. The substrate 100 is provided with a terminal block 200, which is used to connect to the processor 16 to electrically connect the substrate 100 and the processor 16.

[0045] The light-emitting unit 300 is disposed on the substrate 100, and there are multiple light-emitting units 300. Each light-emitting unit 300 has multiple light-emitting chips 310, and the multiple light-emitting chips 310 are used to emit light of at least two different colors.

[0046] There are multiple driving chips 400, and each driving chip 400 is arranged in an array on the substrate 100. Each driving chip 400 is connected to at least one light-emitting unit 300 and is used to drive the corresponding light-emitting unit 300 to emit light.

[0047] The first line group 500 is connected between multiple driver chips 400, and the multiple driver chips 400 are connected in series to the terminal 200 through the first line group 500. The first line group 500 is configured to constitute the address lines of the driver chips 400.

[0048] The second line group 600 is connected between multiple driver chips 400, and the multiple driver chips 400 are connected in series to the terminal 200 through the second line group 600. The second line group 600 is configured to form the data line of the driver chip 400.

[0049] With the above configuration, each driver chip 400 connected to the first line group 500 and each driver chip 400 connected to the second line group 600 are connected in series. The second line group 600 can extend in the same or similar direction as the first line group 500. This can reduce or even avoid the first line group 500 and the second line group 600 crossing each other, thereby reducing or even avoiding the use of bridging structures and reducing the cost of the lamp board 12 and the display device 10.

[0050] The components and technical solutions of the display device 10 and the lamp board 12 of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0051] Please refer to Figure 1 The display device 10 provided in this application embodiment may include at least one of the following devices with display functions: television, computer, monitor, display screen, virtual reality (VR) device, or augmented reality (AR) device. The following embodiments of this application will use a television as an example for describing the display device 10; however, the display device 10 in this application embodiment is not limited to a television.

[0052] For ease of explanation, the width direction of the display device 10 is defined as the first direction x, and the length direction of the display device 10 is defined as the second direction y. There is an angle between the first direction x and the second direction y. The first direction x can be perpendicular or approximately perpendicular to the second direction y.

[0053] The display device 10 may include a housing 10a, which can be used to support, fix and protect other components inside the display device 10 to ensure that the display device 10 can work normally and stably.

[0054] Please combine Figure 1 and Figure 2 The display device 10 includes a display panel 10b disposed on the housing 10a and used to display an image. The display panel 10b includes a backlight module 11 for emitting light and has an emitting side and a backlight side disposed opposite to each other. Accordingly, the emitting side of the backlight module 11 is the side of the display panel 10b from which the image is displayed.

[0055] The display panel 10b also includes a liquid crystal panel 14. The liquid crystal panel 14 and the backlight module 11 are arranged in the thickness direction of the display panel 10b. The liquid crystal panel 14 is located on the light-emitting side of the backlight module 11 and is used to receive the light emitted by the backlight module 11. The liquid crystal panel 14 may include a liquid crystal driving circuit (not shown) and a plurality of liquid crystal molecules 14a. The liquid crystal driving circuit can apply a voltage to the liquid crystal molecules 14a, so that the liquid crystal molecules 14a can be deflected to adjust the transmittance of light on different pixels to control the intensity of light transmitted through each pixel, thereby adjusting the grayscale of the image displayed on the display panel 10b.

[0056] The backlight module 11 includes a lamp panel 12, which is used to emit light. Accordingly, the light-emitting side of the lamp panel 12 is the light-emitting side of the backlight module 11, and the backlight side of the lamp panel 12 is the backlight side of the backlight module 11.

[0057] The backlight module 11 also includes an optical film layer 13, which and the lamp panel 12 are arranged in the thickness direction of the display panel 10b, with the optical film layer 13 located on the light-emitting side of the lamp panel 12. The optical film layer 13 can be used to adjust the path, direction, or polarization state of the light emitted by the lamp panel 12, so that the backlight module 11 emits light with uniform brightness, controllable direction, and pure color.

[0058] For example, the number of optical film layers 13 can be one or more. When the number of optical film layers 13 is multiple, the multiple optical film layers 13 can be stacked on the light-emitting side of the lamp panel 12. The optical film layer 13 can include at least one of a light-diffusing sheet, a prism sheet, and a diffuser sheet. The light-diffusing sheet can be used to uniformly distribute light, the prism sheet can be used to refract or reflect light, and the diffuser sheet can be used to diffuse light. Of course, the optical film layer 13 can also include other light-processing film layers 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 13.

[0059] The display panel 10b may also include a color filter 15, which is disposed on the side of the liquid crystal panel 14 away from the backlight module 11. The color filter 15 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. Understandably, the light passing through the color filter 15 consists of red, green, and blue light of different intensities, enabling the display panel 10b to achieve full-color display.

[0060] Therefore, in the thickness direction of the display panel 10b, the lamp plate 12, the optical film layer 13, the liquid crystal panel 14, and the color filter 15 are arranged sequentially. The optical film layer 13, the liquid crystal panel 14, and the color filter 15 are all located on the light-emitting side of the lamp plate 12. The optical film layer 13 is located between the lamp plate 12 and the liquid crystal panel 14, and the liquid crystal panel 14 is located on the side of the optical film layer 13 away from the lamp plate 12. The liquid crystal panel 14 is located between the optical film layer 13 and the color filter 15, and the color filter 15 is located on the side of the liquid crystal panel 14 away from the lamp plate 12.

[0061] Please refer to Figure 3 The display device 10 also includes a processor 16, which is disposed within the housing 10a and may be located on the backlight side of the backlight module 11 in the display panel 10b. The processor 16 can be electrically connected to the backlight module 11 to control the backlight module 11 to emit light. The processor 16 can also be electrically connected to the liquid crystal panel 14 to control the deflection angle of the liquid crystal molecules 14a in the liquid crystal panel 14, thereby adjusting the grayscale of the image displayed on the display panel 10b.

[0062] In one example, the processor 16 may include a main chip, a timing controller (TCON) chip (hereinafter referred to as the TCON chip), and a buffer controller (BCON) chip (hereinafter referred to as the BCON chip). The TCON chip and the BCON chip are connected in parallel to the main chip. Furthermore, the TCON chip is connected to the LCD panel 14, and the BCON chip is connected to the backlight board 12.

[0063] The main chip receives video signals and decodes them into image data signals and backlight control signals. The TCON chip receives image data signals and can control the LCD panel 14 according to the image data signals. The BCON chip receives backlight control signals and can control the lamp board 12 according to the backlight control signals.

[0064] In one implementation, the processor 16 may have three circuit boards. For example, the processor 16 may include a motherboard 16a, a central control board 16b, and a driver board 16c. The main chip may be located on the motherboard 16a, the TCON chip on the driver board 16c, and the BCON chip on the central control board 16b. The central control board 16b and the driver board 16c are connected in parallel to the motherboard 16a to connect the TCON chip and the BCON chip in parallel to the main chip.

[0065] In another implementation, the processor 16 may have a circuit board on which the main chip, TCON chip, and BCON chip are all located.

[0066] The display device 10 may further include a power supply circuit 17, which supplies power to the light-emitting chip 310 in the light-emitting unit 300 on the lamp board 12 that emits at least two different colors of light. For example, the power supply circuit 17 can supply power to the light-emitting unit 300 via two power supplies. Alternatively, the power supply circuit 17 can also supply power to the light-emitting unit 300 via multiple power supplies, so that the light-emitting chip 310 emits multiple different colors of light.

[0067] The driver chip 400 is electrically connected to the light-emitting unit 300 and the BCON chip of the processor 16, and can transmit a first feedback signal to the BCON chip according to the working status of the light-emitting unit 300. The processor 16 is also electrically connected to the power supply circuit 17. The processor 16 can obtain the working status of the light-emitting unit 300 according to the first feedback signal, and transmit a second feedback signal to the power supply circuit 17 to adjust the power supply voltage of the power supply circuit 17, thereby controlling the light-emitting unit 300 to emit light.

[0068] Please combine Figure 1 and Figure 4 This application provides a light panel 12, which can be multiple light panels, and each light panel 12 can be sequentially arranged along the length direction of the display device 10. The length direction of each light panel 12 can be parallel or approximately parallel to the width direction of the display device 10, and the width direction of each light panel 12 can be parallel or approximately parallel to the length direction of the display device 10. That is, the width direction of the light panel 12 can be parallel or approximately parallel to the second direction y, and the length direction of the light panel 12 can be parallel or approximately parallel to the first direction x.

[0069] The lamp panel 12 includes a substrate 100, which may be made of at least one material selected from aluminum, copper, or ceramic. The substrate 100 has a first side 110, a second side 120, a third side 130, and a fourth side 140 connected sequentially. The first side 110 and the third side 130 are disposed opposite each other on both sides of the lamp panel 12 and both extend along a first direction x. The second side 120 and the fourth side 140 are disposed opposite each other on both sides of the lamp panel 12 and both extend along a second direction y. The second side 120 is adjacent to one end of the first side 110 and one end of the third side 130, and the fourth side 140 is adjacent to the other end of the first side 110 and the other end of the third side 130.

[0070] In this embodiment, the first side 110 and the third side 130 can be the long sides of the substrate 100, and the second side 120 and the fourth side 140 can be the short sides of the substrate 100. Alternatively, the first side 110 and the third side 130 can also be the short sides of the substrate 100, and the second side 120 and the fourth side 140 can also be the long sides of the substrate 100. The following embodiments of this application will be described using the first side 110 as an example of the long side of the substrate 100.

[0071] Please refer to Figure 5 The substrate 100 is provided with a terminal block 200, which may include at least one of a PH2.0 connector or an XH2.54 connector. The terminal block 200 is used to connect to the processor 16 to connect the lamp board 12 to the processor 16. For example, the processor 16 may be connected to the end of the terminal block 200 located on the backlight side of the lamp board 12.

[0072] Please combine Figure 3 and Figure 5 The lamp panel 12 also includes multiple light-emitting units 300, which can be arrayed on the substrate 100. Each light-emitting unit 300 has multiple light-emitting chips 310, which can include at least one of mini light-emitting diodes (Mini LEDs) or micro light-emitting diodes (Micro LEDs).

[0073] Each light-emitting chip 310 is used to emit light of at least two different colors. In one example, the light-emitting unit 300 may include a first light-emitting chip, a second light-emitting chip, and a third light-emitting chip. The first light-emitting chip can be used to emit red light, the second light-emitting chip can be used to emit blue light, and the third light-emitting chip can be used to emit green light. This application embodiment does not limit the number of the first, second, and third light-emitting chips in a single light-emitting unit 300; each of the first, second, and third light-emitting chips can be one, two, or more.

[0074] In another example, the light-emitting unit 300 may include a first light-emitting chip and a second light-emitting chip, which are used to emit any one of red light, blue light and green light, respectively, and the light emitted by the first light-emitting chip and the second light-emitting chip are different colors.

[0075] Please combine Figures 4 to 6 The lamp board 12 also includes a plurality of driver chips 400, which can be arrayed on the substrate 100. Each driver chip 400 is connected to at least one light-emitting unit 300 and is used to drive the corresponding light-emitting unit 300 to emit light. This embodiment does not limit the number of light-emitting units 300 connected to each driver chip 400; for example, each driver chip 400 can be connected to two, four, six, or eight light-emitting units 300. Of course, the driver chip 400 can also be connected to other numbers of light-emitting units 300.

[0076] like Figure 6 As shown, the lamp board 12 also includes a first circuit group 500, which is disposed on the substrate 100 and connected between multiple driver chips 400, so as to connect multiple driver chips 400 in series between the input port 220 and the output port 210 of the terminal block 200, and then connect each driver chip 400 to the processor 16.

[0077] The first line group 500 can be configured to form the address lines of the driver chip 400. The first line group 500 can be connected to the serial data input (DIS) port and the serial data output (DOS) port of the driver chip 400. The processor 16 can transmit address information to each driver chip 400 through the first line group 500.

[0078] In one embodiment, the first line group 500 may include multiple first trace segments 510 extending along a first direction x, and multiple second trace segments 520 extending along a second direction y. The multiple first trace segments 510 may be arranged sequentially along the second direction y, and each first trace segment 510 may be connected in series between different driver chips 400. For example, the first trace segments 510 may be connected in series between at least two driver chips 400 spaced apart along the first direction x.

[0079] The second trace segment 520 connects to the driver chips 400 connected in series by different first trace segments 510, so as to connect multiple driver chips 400 on different first traces connected by the second trace segment 520 in series. For example, the second trace segment 520 can be connected between two adjacent first traces arranged in the second direction y, and the second trace segment 520 can be connected to any two driver chips 400 arranged at intervals along the second direction y on the two first traces.

[0080] The signal transmission directions of the two first traces 510 connected by the second trace 520 can be opposite, or the signal transmission directions of the two first traces 510 connected by the second trace 520 can be the same.

[0081] The first trace segment 510 and the second trace segment 520 are alternately arranged and connected in sequence to connect multiple driver chips 400 on each first trace in series. With the above arrangement, the first circuit group 500 can connect multiple driver chips 400 on the substrate 100 in series to the terminal block 200.

[0082] In one embodiment, the driver chip 400 may include a first driver chip 410 and a second driver chip 420 spaced apart in a first direction x. Each first trace segment 510 may have one first driver chip 410 and one second driver chip 420, and the first driver chip 410 and the second driver chip 420 may be respectively connected to opposite ends of the first trace segment 510. On each first trace segment 510, at least one driver chip 400 may be connected in series between the first driver chip 410 and the second driver chip 420, or the first driver chip 410 and the second driver chip 420 may be arranged adjacent to each other.

[0083] In the signal transmission direction of the first line group 500, one of the first driver chip 410 and the second driver chip 420 can be located at the beginning of the first trace segment 510, and the other can be located at the end of the first trace segment 510. On two adjacent first traces arranged in the second direction y, the first driver chip 410 on one first trace can be located at the beginning in the signal transmission direction, and the first driver chip 410 on the other first trace can be located at the end in the signal transmission direction.

[0084] In this configuration, the first driver chips 410 of two adjacent first trace segments 510 are interconnected. For example, the first driver chips 410 of two adjacent first trace segments 510 can be interconnected through a second trace segment 520. Alternatively, the second driver chips 420 of two adjacent first trace segments 510 are interconnected. For example, the second driver chips 420 of two adjacent first trace segments 510 can be interconnected through a second trace segment 520.

[0085] With the above settings, the second wiring segment 520 can connect multiple first wiring segments 510 sequentially end to end to connect multiple driver chips 400 on different first wirings in series, and can simplify the wiring of the first circuit group 500 and reduce the production difficulty of the lamp board 12.

[0086] In some implementations, at least one of the first driver chip 410 and the second driver chip 420 on a first trace segment 510 may be disposed near the edge of the substrate 100.

[0087] In some implementations, each first driving chip 410 can be spaced apart along the second direction y, and each second driving chip 420 can also be spaced apart along the second direction y.

[0088] In the above embodiments, the first line group 500 can be arranged in an "S" shape or a near "S" shape. Of course, in other embodiments, the first line group 500 can also connect the driver chips 400 in series through other wiring methods, and the wiring method of the first line group 500 is not limited to an "S" shape.

[0089] In some implementations, in the signal transmission direction of the first line group 500, the trace length between the driver chip 400 at the beginning of the first line group 500 and the terminal 200 is L1, and the trace length between the driver chip 400 at the end of the first line group 500 and the terminal 200 is L2. In one example, L1 can be greater than L2. In another example, L2 can be greater than L1.

[0090] In one embodiment, please combine Figure 7 , Figure 8 as well as Figure 9 In the second direction y, the terminal 200 may be located near the center of the first side 110 and the third side 130. Accordingly, in the second direction y, the number of first wiring segments 510 located between the terminal 200 and the first side 110 may be equal to or approximately equal to the number of first wiring segments 510 located between the terminal 200 and the third side 130.

[0091] In another embodiment, such as Figure 6As shown, in the second direction y, the terminal 200 can be positioned closer to the third side 130 than the first side 110. For example, the terminal 200 can be located at the edge of the substrate 100 near the third side 130.

[0092] Correspondingly, in the second direction y, the number of first wiring segments 510 located between the terminal 200 and the first side 110 can be greater than the number of first wiring segments 510 located between the terminal 200 and the third side 130. In one example, each first wiring segment 510 can be located on the side of the terminal 200 closer to the first side 110.

[0093] In the above embodiments, at least two of the plurality of first wiring segments 510 may be disposed on the side of the terminal 200 near the first side 110.

[0094] In one embodiment, such as Figure 6 As shown, in the first direction x, the terminal block 200 can be positioned close to the center of the second side 120 and the fourth side 140. Accordingly, in the first direction x, the number of first wiring segments 510 located between the terminal block and the second side 120 can be equal to or approximately equal to the number of first wiring segments 510 located between the terminal block 200 and the fourth side 140.

[0095] In another embodiment, such as Figure 9 As shown, in the first direction x, the terminal 200 can be positioned closer to the second side 120 than the fourth side 140. Correspondingly, in the first direction x, the number of first wiring segments 510 located between the terminal 200 and the fourth side 140 can be greater than the number of first wiring segments 510 located between the terminal 200 and the second side 120. In one example, each first wiring segment 510 can be located on the side of the terminal 200 closer to the fourth side 140.

[0096] In the above embodiments, there may be two first line groups 500, and each of the two first line groups 500 may include multiple first wiring segments 510 and second wiring segments 520. Furthermore, the two first line groups 500 may be symmetrically or approximately symmetrically arranged on both sides of the terminal block 200.

[0097] In one example, such as Figure 6 As shown, one first line group 500 can be located on the side of terminal 200 near the second side 120, and another first line group 500 can be located on the side of terminal 200 near the fourth side 140. In another example, as... Figure 9As shown, a first line group 500 may be located on the side of terminal 200 near the first side 110, and another first line group may be located on the side of terminal 200 near the third side 130.

[0098] Please refer to Figure 6 and Figure 9 The lamp board 12 also includes a second circuit group 600, which is disposed on the substrate 100 and connected between multiple driver chips 400, so as to connect multiple driver chips 400 in series between the input port 220 and the output port 210 of the terminal block 200, and then connect each driver chip 400 to the processor 16.

[0099] The second line group 600 can be configured to form the data lines of the driver chip 400. The second line group 600 can be connected to the parallel data input (DIP) port and parallel data output (DOP) port of the driver chip 400. The processor 16 can transmit data information to each driver chip 400 through the second line group 600. The second line group 600 and the first line group 500 can transmit signals in the same direction.

[0100] Therefore, the processor 16 can transmit addressing information and data information to the driver chip 400 through the first line group 500 and the second line group 600 respectively, so as to control each light-emitting unit 300 to emit light in sequence and realize the display function of the display device 10.

[0101] With the above configuration, each driver chip 400 connected to the first line group 500 and each driver chip 400 connected to the second line group 600 are connected in series. The second line group 600 can be routed in the same or similar direction as the routing direction of the first line group 500. This can reduce or even avoid the crossing between the first line group 500 and the second line group 600, thereby reducing or even avoiding the use of bridging structures and reducing the cost of the lamp board 12 and the display device 10.

[0102] In the example above, the second line group 600 can also be configured as a power line constituting the driver chip 400.

[0103] In one embodiment, the routing of the second line group 600 can be the same as that of the first line group 500, and the second line group 600 and the first line group 500 can be connected in series with the same driver chip 400. This avoids the first line group 500 and the second line group 600 crossing over each other, thus avoiding the use of a bridging structure and reducing the cost of the lamp board 12 and the display device 10. The routing of the second line group 600 can refer to the routing of the first line group 500 described above, and will not be repeated here.

[0104] In one embodiment, please refer to Figure 6 and Figure 9 The first line group 500 and the second line group 600 are respectively connected to the same output port 210 of the terminal block 200. This configuration saves on the output port 210 of the terminal block 200, reducing costs.

[0105] Of course, in other embodiments, such as Figure 10 As shown, the first line group 500 and the second line group 600 can be connected to different output ports 210 of the terminal block 200.

[0106] In one embodiment, please refer to Figure 6 and Figure 9 In the transmission direction of the second line group 600, the driver chip 400 located at the end of the second line group 600 is connected to the input port 220 of the terminal block 200 through the first line group 500. This configuration saves the input port 220 of the terminal block 200, reducing costs.

[0107] In one embodiment, the distance between the driver chip 400 at the beginning of the second line group 600 and the terminal 200 is the smallest compared to other driver chips 400. Therefore, the signals transmitted by the second line group 600 are less susceptible to interference.

[0108] Please refer to Figure 10 In one embodiment, the lamp board 12 may further include a third circuit group 700, which is disposed on the substrate 100 and connected between multiple driver chips 400. The third circuit group 700 may be configured to form power lines for the driver chips 400, thereby supplying power to each driver chip 400 through the third circuit group 700.

[0109] The third line group 700 can connect multiple driver chips 400 in series between the input port 220 and the output port 210 of the terminal block 200. Thus, the driver chips 400 connected to the first line group 500, the second line group 600, and the third line group 700 are all connected in series, and the first line group 500, the second line group 600, and the third line group 700 can all be routed in the same or similar directions. Through this arrangement, the crossing between the first line group 500, the second line group 600, and the third line group 700 can be reduced or even avoided, thereby reducing or even eliminating the use of bridging structures and reducing the cost of the lamp board 12 and the display device 10.
