结合现有技术中常见的一种液晶显示装置结构局部剖视图图1,说明现有技术中存在的缺陷。现有技术中超薄挂墙式液晶显示装置多采用背包设计,液晶显示装置100中,前框110外观框部分、面板111、导光板112、散热器113以及驱动板117、后壳119在厚度方向上占据了空间,不利于液晶显示装置的薄型化,尤其是散热器113与驱动板117的翻转固定设计,使得液晶显示装置侧视呈台阶结构,不利于液晶显示装置的贴墙悬挂。

实施例一
本申请实施例提供一种背光模组,如图2所示,为本申请实施例中背光模组的局部结构示意图。一种背光模组200包括,面板210,前框211,中框212,支撑框213,导光板214,背板215,LED灯条216、PCB板217,驱动板218。其中,导光板214侧面包括一入光侧;背板215设置在导光板214下方,在与导光板214相对一侧设置有背板凹槽2151,在垂直于导光板214入光侧向外的方向上,背板215的长度大于导光板214的长度;中框212设置在背板215上方,中框214包括一与背板215边缘抵接的凸台;支撑框213与位于背板215上方,且介于中框212与导光板214入光侧之间,支撑框213与中框212,背板215间形成一矩形空腔,该矩形空腔用于放置驱动板218;LED灯条216设置在导光板214入光侧;PCB板介于导光板214与背板凹槽2151之间,且与LED灯条连接。
进一步地,背板215采用散热系数良好的材料,使得背板215在起到固定与支撑作用的同时,还能代替现有技术中散热器的作用,在液晶显示装置正常工作时,实现热量传导与散热功能,这样避免了散热器的使用,在液晶显示装置的厚度上,省去了散热器的尺寸,进而减小液晶显示装置的整体厚度,实现液晶显示装置的薄型化。
优选地,背板215选用材料为铝材。
进一步地,如图3所示,本申请实施例中PCB板217外形为L型,L型立端2171为出线端,与LED灯条216电性连接,L型底端2172为布线端,背板凹槽2151的长度大于L型底端2172的长度,使得L型底端2172能完全固定在背板凹槽2151内侧底面,实现对PCB板217的固定连接以及增大PCB板217与背板凹槽2151整体接触面积,更好地实现PCB板217的热量传导与散发。
优选地,L型底端与背板凹槽2151为粘接。
进一步地,如图2所示,支撑框213与前框211间留有空隙,该空隙厚度大于柔性线缆219厚度,进而在装配时,柔性线缆219穿过该空隙,电性连接驱动板218与面板210,实现面板210正常工作。
进一步地,为保证液晶显示装置在正常工作时有强度足够、光线均匀的背光亮度,本申请实施例LED灯条216为灯条组,数量为多个,且均匀的分布在L型立端2171上,图3为LED灯条216在PCB板217上均匀分布的结构示意图。PCB板217为LED灯条216提供电源以及对灯光强度的控制,实现为液晶显示装置提供可调节的匀强亮光的作用。
进一步地,LED灯条216产生的热量通过PCB板217传导到背板215,实现热量的散发。
进一步地,如图2所示,本申请实施例中驱动板218放置在中框212与支撑框213间矩形空腔,固定在背板215上,中框212与支撑框213间矩形空腔高度大于或等于驱动板218的整体高度,空腔长度大于或等于驱动板218的整体长度。与现有技术中驱动板117的翻转固定在背板113后方相比,驱动板217放置在中框212与支撑框213矩形空腔间的方式,在厚度方向上省去了固定驱动板217所需的空间尺寸,进一步减小液晶显示装置的在厚度上的尺寸,消除了现有技术中的背包设计与台阶结构,实现液晶显示装置的超薄贴墙设计。
进一步地,支撑框213、中框212设有凸台,中框212凸台高度等于背板215的厚度,支撑框213凸台高度等于所述背板凹槽2151的深度;
优选地,驱动板218、支撑框213以及中框212与背板215的连接方式均采用粘接。
优选地,本申请实施例前框211采用0.2mm级别的刚性材料制作。图4为前框与面板装配局部示意图。如图4所示,面板210由上偏振片2101、CF玻璃2102以及TFT玻璃2103三层结构组成,上偏振片2101与CF玻璃2102间形成台阶部,厚度为0.2mm级别的刚性材料制成的前框211粘接与CF玻璃2102的上表面与中框212上,上偏振片2101与中框212边缘凸起起到限位作用,实现面板210外侧与前框211外侧齐平的效果,在保证前框211足够的刚性强度的同时,优化了液晶显示装置的外观,实现液晶显示装置前表面平齐无凸起的设计。
实施例二
可选地,本申请实施例二提供冲压加工和机加工两种背板凹槽加工方式。如图5A所示,为采用冲压加工的方式形成的背板凹槽2151。采用冲压加工的优点是:背板凹槽2151加工效率高,背板215的厚底小,液晶显示装置的整体厚度最小;缺点是:冲压加工会在背板215外表面形成冲压凸起,使得背板215外表面存在高度差,背面无法完全平齐,对液晶显示装置的完全贴墙悬挂造成一定影响。
优选地,如图5B所示,背板凹槽3151采用机加工的方式形成。与冲压加工的方式相比,机加工的优点是:背板外表面完全平齐无高度差,整个液晶显示装置整体为平齐无台阶设计,有利于实现液晶显示的完全贴墙悬挂设计;缺点是:为保证机加工形成背板凹槽3151具有一定的强度度,需要背板315具有的厚度比冲压加工的背板215的厚度大,造成液晶显示装置的整体厚度增加,不利于液晶显示装置的薄型化,但与现有技术相比,本实施例优选的液晶显示装置整体厚度远小于现有技术中液晶显示装置的整体厚度。
与现有技术相比,本申请实施例所提出的技术方案的有益技术效果包括:
本发明申请提供的一种背光模组及液晶显示装置,其中,背光模组包括:前框、中框、支撑框、背板、导光板、LED灯条、PCB板与驱动板,导光板侧面包括一入光侧;背板设置在导光板下方,在与导光板相对一侧设置有背板凹槽,在垂直于导光板入光侧向外的方向上,背板的长度大于导光板的长度;中框设置在背板上方,中框包括一与背板边缘抵接的凸台;支撑框与位于背板上方,且介于中框与导光板入光侧之间,支撑框与中框,背板间形成一矩形空腔,该矩形空腔用于放置驱动板;LED灯条设置在导光板入光侧;PCB板介于导光板与背板凹槽之间,且与LED灯条连接。
本发明申请提供的背光模组中,背板采用散热系数良好的材料,使得背板在起到固定与支撑作用的同时,还能代替现有技术中散热器的使用,实现热量的传导与散发,从而避免散热器的使用,在液晶显示装置的厚度空间上,省去了散热器的尺寸,进而减小液晶显示装置的整体厚度,实现液晶显示装置的薄型化;同时,PCB板外形为L型,包括与LED灯条电性连接的立端以及与背板固定的底端,增到了与背板的接触面积,更好地实现LED灯条与PCB板热量的传导与散发,并且在厚度空间上减小PCB板所占的尺寸,从而进一步减小液晶显示装置的整体厚度;在中框与支撑框间设置矩形空腔,驱动板防置在矩形空腔内,固定在背板上,与现有技术中驱动板的翻转固定在被板后方的方式相比,本申请中驱动板固定方式在厚度方向上省去了固定驱动板所需的空间尺寸,进一步减小液晶显示装置的厚度,消除了现有技术中的背包设计与台阶结构,有利于实现液晶显示装置的超薄贴墙设计。
实施例三
本申请实施例三还提供一种液晶显示装置,包含面板210和上述实施例一和实施例二中所述的背光模组200。其中,背光模组200与面板210相对设置,面板210位于背光模组200上表面;背光模组200的结构、功能与作用已在前述实施例中详细说明,此处不再赘述。
最后应说明的是:以上各实施例仅用以说明本发明中的技术方案,而非对其限制;尽管参照前述各实施例对本发明进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分或者全部技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
