1. a backlight assembly, including:

  • Waveguide plate, is used for guiding light;

    First light emitting module, is placed on the first side of described waveguide plate, described firstOptical module includes multiple first light-emitting block;

    Second light emitting module, is placed on the second side of described waveguide plate, described secondOptical module includes multiple second light-emitting block,Multiple optical drives, for multiple described first light-emitting blocks and multiple describedThe luminance level of the second light-emitting block is controlled;

    AndData optical signal control module, it is based on picture signal generation the most right to receiveIn the representative image signal of multiple displaying blocks, and should provide to described optical driveCorresponding to the data optical signal of described representative image signal,Wherein, at least one first light-emitting block in multiple described first light-emitting blocks, manyAt least one second light-emitting block in individual described second light-emitting block and multiple described lightAt least one optical drive learned in driver is connected to each other,Wherein, the first end of at least one the first light-emitting block described be connected to described at leastOne optical drive, the second end of at least one the first light-emitting block described is connected to instituteState the first end of at least one the second light-emitting block, and at least one second luminescence describedSecond end of block is connected at least one optical drive described;

    Wherein, the second end of at least one the first light-emitting block described with described at least oneConnection between first end of the second light-emitting block is not by least one optics describedDriver and connect, and cross described waveguide plate,Wherein, the second end of at least one the first light-emitting block described is positioned at the of waveguide plateSide, and the first end of at least one the second light-emitting block described is positioned at the of waveguide plateTwo sides,Wherein, the first side of described waveguide plate and the position each other, the second side of described waveguide platePut relatively,Each in multiple described first light-emitting blocks includes being placed in described firstMultiple luminescent devices in optical module;

    Each in multiple described second light-emitting blocksIncluding the multiple luminescent devices being placed in described second light emitting module;

    Described first is luminousModule includes the first support unit and the first routing cell, at described first support unitOn the luminescence of each the first light-emitting block that is formed in multiple described first light-emitting blockDevice, and in described first routing cell, it is formed with multiple described first light-emitting blockIn the wire of luminescent device of each the first light-emitting block;

    Described second light emitting moduleIncluding the second support unit and the second routing cell, shape on described second support unitBecome the luminescent device of each the second light-emitting block having in multiple described second light-emitting block,And be formed in multiple described second light-emitting block in described second routing cellThe wire of the luminescent device of each the second light-emitting block;

    And described first support unitIt is facing with each other with described second support unit,Described first light emitting module farther includes the 3rd routing cell, described 3rd clothLine unit makes the luminescent device and described first being formed on described first support unitWire electrical connection in routing cell;

    Described second light emitting module farther includes the 4thRouting cell, described 4th routing cell makes to be formed on described second support unitLuminescent device electrically connects with the wire in described second routing cell;

    And the described 3rdAfter routing cell and described 4th routing cell are placed in described waveguide plate,Described 3rd routing cell and described 4th routing cell prolong in a first directionStretch;

    One end that described first routing cell includes being connected to described 3rd routing cell andThe first area that extends in said first direction and be different from described first partyTo the upwardly extending second area of second party;

    And described second routing cell includesIt is connected to one end of described 4th routing cell and extends in said first directionFirst area and the second area extended in this second direction, wherein;

    Each in described first routing cell and described second routing cell is wrappedInclude folded portion;

    And in described first routing cell and described second routing cellEach direction extended changes in office, described folding part.
