When in lamp plate 1 when the quantity in target lamp district 11 is N, there is the unable condition of arranging of connecting wire of lamp pearl in N lamp districts of lamp plate 1, need be in first connector 12 with respectively increase 2N at least pins in the second connector 21, specifically do: at least N of the first pins 121 and at least N of the second pins 122 are added to the first connector 12, and at least N of the third pins 211 and at least N of the fourth pins 212 are added to the second connector 21.
In the lamp panel 1, N is the number of the target lamp zones 11 located near the first connector 12, that is, the connection lines of the lamp beads of the target lamp zones 11 cannot be arranged due to the first connector 12 and the connection lines of the first connector 12. When the lamp panel 1 includes a plurality of the first connectors 12, the target lamp area 11 may exist near each of the first connectors 12.
In the embodiment of the present application, the definition of the first connector 12 includes a cathode pin connected to the driving chip, a positive voltage VLED for each of the lamp beads to operate, and 2N pins added in the embodiment of the present application. In the embodiment shown in fig. 3, lamp panel 1 may include 80 lamp zones, each of which is connected to first connector 12, so that first connector 12 includes 80 cathode pins, and the current of VLED requires that the connection line of VLED is not less than 15 pins, and on the basis of the above 95 pins, first pin 121 and second pin 122 are added to first connector 12 in the implementation shown in fig. 3, that is, first connector 12 at least includes 97 pins. When the number of pins is too large, the first connector 12 has high processing difficulty and low reliability, and can be divided into a plurality of sub-connectors. That is, the first connector 12 and the second connector 21 described in the embodiment of the present application may each include one or more than one connector, the number of the specific connectors is set according to actual needs, and the number of the connectors is not limited in the embodiment of the present application.
As shown in fig. 5, the embodiment shows a backlight driving circuit of the display device, and the display device may include a plurality of light panels 1 and one driver board 2, for example, four light panels 1, where the four light panels 1 are all connected to the driver board 2. Specifically, the first connector 12 of the lamp panel 1 is connected to the second connector 21 of the driver board 2, and the second connector 21 is connected to the driver chip 22 of the driver board 2, so as to form a backlight driving circuit of the display device.
In the embodiment shown in fig. 6, display device may be a display module block diagram of a television, display device may include 16 lamp panel 1 and two drive plate 2, every lamp panel 1 all includes two first connector 12, every lamp panel 1 includes 112 lamp area, the base plate of lamp panel 1 is the individual layer PCB board, the base plate is provided with two mounting grooves that are used for installing first connector 12, sets up behind the mounting groove, makes lamp panel 1's 112 some in the lamp area be target lamp area 11, and partial lamp area exists the lamp pearl that the connecting wire can't arrange promptly. By adopting the structure of each embodiment, pins are added to the first connector 12 and the second connector of the driving board 2, so that the arrangement of the connecting lines of the target lamp area 11 in a single-layer PCB can be realized, and the cost of the lamp panel 1 is reduced.
An embodiment of the present application further provides an electronic device, where the electronic device includes the display apparatus described in any of the above embodiments, for example, the display apparatus may be a display device such as a television or a display.
In the embodiment of this application, through lamp plate 1 first connector 12 and drive plate 2 increase 2N pins on the basis of the original structure of second connector 21, will 2N pins of first connector 12 with 2N pin one-to-one of second connector 21 is connected, and will in lamp plate 1 each target lamp district 11 first lamp pearl 111 with second lamp pearl 112 is connected to first connector 12 respectively the pin for each that the connecting wire can't be arranged target lamp district 11 first lamp pearl 111 with second lamp pearl 112 passes through drive plate 2 second connector 21 connects, makes when lamp plate 1 is the individual layer PCB board still can realize the lamp district includes a plurality of lamp pearls.
The above description is only a specific implementation of the embodiments of the present application, but the scope of the embodiments of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the embodiments of the present application should be covered by the scope of the embodiments of the present application. Therefore, the protection scope of the embodiments of the present application shall be subject to the protection scope of the claims.
