Material be preferably be molybdenum (Mo) or aluminium (Al).Base of the conductive grid 412 by sputtering technology formation in OLED screen body 4
On plate and the outer perimeter of each light-emitting zone 411 is covered, the later stage passes through conductive grid 412 according to the luminous pattern of design
Photoetching process forms required figure.There is clearance for insulation, between insulation between the conductive grid 412 of each OLED luminescence units 41
Gap is the part in grid gap, is realized by clearance for insulation between the conductive grid 412 of each OLED luminescence units 41 mutually absolutely
Edge, it is ensured that the normal work of each conductive grid 412.
Further, as shown in Figure 1 and Figure 5, OLED intelligences combinations back light also includes the pinboard 7 of two pieces or so arrangements,
Every piece of OLED screen body 4 is all connected by a FPC flexible PCBs 8 with the pinboard 7, therefore FPC flexible PCBs 8 also have 10
Block；In 10 pieces of pinboards 7, it is connected with four pieces of OLED screen bodies 4 for being located at the right side of mounting bracket 3 in two rows OLED screen body 4
Four pieces of FPC flexible PCBs 8 be connected with the pinboard 7 on right side, the OLED that the pinboard 7 on right side and one piece are located at right side is controlled
Making sheet 5 is connected；With being located at six pieces that six pieces of OLED screen bodies 4 in the left side of mounting bracket 3 are connected in two rows OLED screen body 4
FPC flexible PCBs 8 are connected with the pinboard 7 in left side, the pinboard 7 in left side and one piece of OLED control panel 5 positioned at left side
Be connected, thus pinboard 7 by a plurality of connection line 83 on each FPC flexible PCBs 8 collect after with the phase of OLED control panels 5
Connection, efficiently reduces the area of OLED control panels 5 and the quantity of plug connector, it is adaptable to which OLED screen body 4 is in vehicle light illumination
The production in enormous quantities in field.
With the increase of the quantity of OLED luminescence units 41, by the electrode and FPC of the OLED luminescence units 41 of each OLED screen body 4
The control circuit that flexible PCB 8 is connected can also be multiplied.Based on this, the application provides each FPC flexible PCBs 8 and each
The preferred wiring construction of OLED screen body 4：As shown in Figure 12 to Figure 14, the back side of every piece of OLED screen body 4 all offers left and right extension
Accepting groove 44, the electrode of each OLED luminescence units 41 be all located on the back side of the OLED screen body 4 exposed from accepting groove 44 and
Along the bearing of trend linear arrangement from left to right of accepting groove 44；Every piece of FPC flexible PCB 8 all includes circuit board main body portion
81 and be located at the end in circuit board main body portion 81 and the length direction along accepting groove 44 or so extension circuit board connecting portion
82, the circuit board connecting portion 82 is fixed on by way of hot pressing is bound in the accepting groove 44 of OLED screen body 4 so that each FPC
Flexible PCB 8 is fixed on each OLED screen body 4, therefore every piece of OLED screen body 4 goes out to be formed with for fixing FPC flexibilities in accepting groove 44
The binding region 45 of circuit board 8；The a plurality of company drawn from circuit board main body portion 81 is integrated with the circuit board connecting portion 82
Link 83, therefore the joint in circuit board connecting portion 82 and circuit board main body portion 81 forms the wiring branch of FPC flexible PCBs 8
Point, electrode of a plurality of connection line 83 respectively with each OLED luminescence units 41 is connected, and a plurality of connection line 83 is along accepting groove
44 width is arranged side by side successively from top to bottom, therefore circuit board connecting portion 82 and the OLED screen body that exposes from accepting groove 44
4 back side fits so that the width of circuit board connecting portion 82 is consistent with the width of accepting groove 44, be all upper and lower
To the thickness direction of, circuit board connecting portion 82 it is consistent with the thickness direction of OLED screen body 4, be all fore-and-aft direction.Therefore, the application
Cabling is reasonable in design, orderly；And circuit board connecting portion 82 width and binding region 45 width all with accepting groove
44 width is consistent, and the thickness direction of circuit board connecting portion 82 is consistent with the thickness direction of OLED screen body 4, so as to effectively subtract
The thickness and FPC flexible PCBs 8 and the width of the binding region 45 of OLED screen body 4 of few circuit board connecting portion 82, prevent FPC
