Description

一种背光模组及液晶显示装置
技术领域
本发明涉及显示技术领域,尤其涉及一种背光模组及液晶显示装置。
背景技术
背光模组是液晶显示器的关键组件,它能够为液晶显示器提供面光源,使液晶显示器能正常显示影像。目前,背光模组所用的光源主要为发光二极管(Light EmittingDiode,以下简称LED)和冷阴极荧光灯管(Cold Cathode Fluorescent Lamp,简称CCFL);其中,以LED作为光源的LED背光模组所发出的光色域更广,色彩表现能力更好,因此,LED背光模组的生产受到人们的广泛关注。
请参阅图1,在生产以LED作为光源3的LED背光模组时,LED灯条与导光板1组装的过程为:先在柔性电路板2上刷锡膏,将LED贴在柔性电路板2的锡膏上,然后采用回流焊工艺使贴在锡膏上的LED固定在柔性电路板2上,形成LED灯条,接下来将LED灯条中的柔性电路板2与导光板1相连接,以使LED的出光面贴合在导光板1的入光面上,完成LED灯条与导光板1的组装。
然而,在形成LED灯条的过程中,由于回流焊工艺是在较高温度下进行的,在这样的温度下,锡膏会熔化流动,因此,采用回流焊工艺使贴在锡膏上的LED固定在柔性电路板2上时,LED会产生位移,偏离了柔性电路板2上原本为LED设定的位置,导致同一灯条上的LED的出光面与导光板1的入光面之间产生间隙,从而使进入导光板1的光存在背光辉度差及均齐不良的问题。
发明内容
本发明的目的在于提供一种背光模组及液晶显示装置,以解决由同一灯条上的光源的出光面与导光板的入光面之间产生间隙,造成的进入导光板的光存在背光辉度差及均齐不良的问题。
为了实现上述目的,本发明提供如下技术方案:
一种背光模组,包括导光板以及柔性电路板;所述导光板的边缘设有若干光源安装孔,所述光源安装孔沿所述导光板的厚度方向开设;每个所述光源安装孔内安装有光源,所述光源通过连接件安装在所述光源安装孔内,且所述光源的出光面贴在所述光源安装孔的孔壁上;所述柔性电路板上设有若干组与各所述光源安装孔一一对应的正负极导电件,且每组所述正负极导电件对应与所述光源安装孔中光源的正负极相连接。
本发明还提供了一种液晶显示装置,包括上述技术方案所述的背光模组。
与现有技术相比,本发明的有益效果在于:
本发明提供的背光模组中,导光板的边缘设有若干光源安装孔,光源通过连接件安装在光源安装孔内,并使光源的出光面与导光板的入光面贴合在一起,而柔性电路板通过其上设有的正负极导电件,对应与光源上的正负极相连接,实现了柔性电路板向光源供电。柔性电路板向光源供电使光源发光,由于光源的出光面与导光板的入光面贴合在一起,光源发出的光直接进入导光板内,不需要经过多余的路径,避免了光源发出的光在进入导光板前的消耗,而且光源按照光源安装孔的设定位置,均匀的排布的导光板的入光面上,保证了光源发出的光从导光板的入光面上均匀的进入导光板内部,从而解决了进入导光板的光存在背光辉度差及均齐不良的问题。而且,本发明提供的背光模组中,在实现光源与导光板的组装过程中,只需将光源安装在光源安装孔中,不会涉及由于组装人员的熟练度存在差异,而导致光源与导光板之间出现一定程度的偏移问题。
另外,相比于现有技术中,通过回流焊工艺将光源与柔性电路板相连接,来实现柔性电路板向光源供电的方式,本发明将光源固定在光源安装孔中,再通过设置在柔性电路板上的正负极导电件,对应与光源上的正负极相连接,即可实现柔性电路板向光源供电,从而避免了回流焊过程中,锡膏受热熔化导致的光源偏离柔性电路板上原本为光源设定的位置的问题;而且简化了背光模组组装时的操作过程。

具体实施方式
为了进一步说明本发明实施例提供的背光模组及液晶显示装置,下面结合说明书附图进行详细描述。
请参阅图2-图4,本发明实施例提供的背光模组包括导光板1以及柔性电路板2;导光板1的边缘设有若干光源安装孔5,光源安装孔沿导光板的厚度方向开设;每个光源安装孔5内安装有光源3,光源3通过连接件4安装在光源安装孔5内,且光源3的出光面贴在光源安装孔5的孔壁上;柔性电路板2上设有若干组与各光源安装孔5一一对应的正负极导电件8,且每组正负极导电件8对应与光源安装孔5中光源3的正负极相连接。
具体实施时,在导光板1出光面的边缘或出光面相对的底面的边缘,形成光源安装孔5,在光源安装孔5的孔壁上设置连接件4。需要说明的是,导光板1上光源安装孔5的形成方法有很多种,例如通过注塑的方法在导光板1上形成光源安装孔5,该光源安装孔5可以是盲孔或通孔,且光源安装孔5的容积优选地与光源3相匹配,使光源3能够恰好放入光源安装孔5中,这样光源3的出光面就能对应与光源安装孔5的孔壁相接触,防止光源3晃动。
在组装背光模组的过程中,通过连接件4将光源3安装在光源安装孔5中,且光源3的出光面贴在光源安装孔5的孔壁上,即光源3的出光面与导光板1的入光面贴合在一起,并保证光源3的正负极朝向光源安装孔5的开口处,设置在柔性电路板2上的若干组正负极导电件8对应与光源3的正负极相连接,从而保证柔性电路板2能够向光源3供电。柔性电路板2向光源3供电后,使光源3发光,光源3发出的光经过导光板1的入光面进入到导光板1的内部,然后从导光板1的出光面射出,实现背光模组的发光过程。
从本发明实施例提供的背光模组的组装和工作过程可知,背光模组中导光板1的边缘设有若干光源安装孔5,光源3通过连接件4安装在光源安装孔5内,并使光源3的出光面与导光板1的入光面贴合在一起,而柔性电路板2通过其上设有的正负极导电件8,对应与光源3上的正负极相连接,实现了柔性电路板2向光源3供电。柔性电路板2向光源3供电使光源3发光,由于光源3的出光面与导光板1的入光面贴合在一起,光源3发出的光直接进入导光板1内,不需要经过多余的路径,避免了光源3发出的光在进入导光板1前的消耗,而且光源3按照光源安装孔5的设定位置,均匀的排布的导光板1的入光面上,保证了光源3发出的光从导光板1的入光面上均匀的进入导光板1内部,从而解决了进入导光板1的光存在背光辉度差及均齐不良的问题。而且,本发明提供的背光模组中,在实现光源3与导光板1的组装过程中,只需将光源3安装在光源安装孔5中,不会涉及由于组装人员的熟练度存在差异,而导致光源3与导光板1之间出现一定程度的偏移问题。
另外,相比于现有技术中,通过回流焊工艺将光源3与柔性电路板2相连接,来实现柔性电路板2向光源3供电的方式,本发明将光源3固定在光源安装孔5中,再通过设置在柔性电路板2上的正负极导电件8,对应与光源3上的正负极相连接,即可实现柔性电路板2向光源3供电,从而避免了回流焊过程中,锡膏受热熔化导致的光源3偏离柔性电路板2上原本为光源3设定的位置的问题;而且简化了背光模组组装时的操作过程。需要说明的是,正负极导电件8与光源3上的正负极相连接的方式有很多种,例如:将柔性电路板2与导光板1相连,并保证正负极导电件8与光源3上的正负极相接触,但不仅限于此。
需要说明的是,导光板1的厚度方向是指:导光板1的出光面到导光板1的出光面相对的底面的方向。
本发明实施例中提到的连接件4可以与导光板1呈一体结构;或连接件4为与导光板1相连接的独立结构。当连接件4与导光板1呈一体结构时,可以直接通过注塑的方法,在形成光源安装孔5的同时一起形成连接件4,这种方法能够一次成型光源安装孔5和连接件4,且操作简单方便。当连接件4为与导光板1相连接的独立结构时,可选择柔性支撑件作为连接件4,来实现光源3与光源安装孔5的连接。由于柔性支撑件的形状能够根据需要任意变化,因此,将柔性支撑件与光源3相连接时,可以根据光源3与柔性支撑件相接触的表面的平整程度,将柔性支撑件与光源3充分接触,且不会破坏光源3的表面。而柔性支撑件可选的结构很多,但其大部分由环氧树脂胶制成,环氧树脂胶能够在常态下根据需要做成任意结构,且在一定温度下会固化,而本实施例利用其这种性质,通过使用环氧树脂胶制成的连接件4,来实现光源3与光源安装孔5的连接。
请参阅图4,本发明实施例提到的柔性电路板2上设有若干组正负极导电件8,且若干组正负极导电件8与各光源安装孔5一一对应,通过正负极导电件8与光源3的正负极相接触来为光源3供电,使光源3能够发光;接触的过程中,由于光源3与光源安装孔5的连接不牢固,可能会使光源3的正负极与正负极导电件8不能够很好的对位接触,因此,每组正负极导电件8的面积大于对应的光源安装孔中光源3的正负极的面积,保证光源3的正负极与正负极导电件8能够良好的接触,并实现柔性电路板2向光源3供电。上述正负极导电件8的种类有很多,例如:焊盘或导电薄膜,但不仅限于此。
请参阅图3和图5,本发明实施例提到的背光模组中,导光板1的出光面上或与出光面相对的底面上,相邻光源安装孔5之间设有凹槽6,相邻光源安装孔5之间通过凹槽6相连通;相邻光源3之间通过柔性连接板7连接,且柔性连接板7位于凹槽6内。
在将光源3安装在光源安装孔5内的过程中,可以先将光源3通过柔性连接板7连接,形成链状结构,然后所形成的链状结构上的光源3对应安装在光源安装孔5内,所形成的链状结构上的柔性连接板7对应设置在凹槽6内,实现将所形成的链状结构和导光板1组装在一起的目的。相比于将光源3逐个放入光源安装孔5中,上述将链状结构与导光板1组装在一起的方式,方便了光源3与导光板1的组装。另外,由于柔性连接板7可以自由弯曲,采用柔性连接板7将光源3连接在一起,保证了每个光源3能够对应设置在光源安装孔5中。
而由于相邻光源安装孔5之间安装的凹槽6能够容纳柔性连接板7,使相邻光源3之间的柔性连接板7对应安装在凹槽6内,因此,相邻光源安装孔5之间设置的凹槽6,避免了柔性连接板7设在导光板1的表面时占用过多空间的问题。另外,所使用的柔性连接板7具有一定的强度,且能够与凹槽6固定连接,因此,通过使用柔性连接板7方便了光源3与导光板1的组装,而将柔性连接板7与凹槽6固定连接,使光源3能够更为牢固的固定在光源安装孔5内,进一步保证了光源3的出光面与导光板1的入光面贴合在一起。
需要说明的是,柔性连接板7的种类有很多,例如胶带等。而使用胶带作为柔性连接板7,由于其粘度和强度均能满足需要,因此,能够将光源3很好的固定在光源安装孔5中。
另外,上述实施例中的光源安装孔5沿垂直导光板1的出光面的方向贯穿导光板1时,凹槽6和柔性电路板2分别设在导光板1沿其厚度方向的异面上,例如:当凹槽6设于导光板1的出光面上时,柔性电路板2设于导光板1上出光面相对的底面上;或当凹槽6设于导光板1上出光面相对的底面上时,柔性电路板2设于导光板1的出光面上。
而且,光源安装孔5沿垂直导光板1的出光面的方向贯穿导光板1时,光源3在导光板1的出光面一侧的端面,与导光板1的出光面平齐;光源3在出光面相对的底面一侧的端面,与出光面相对的底面平齐。
上述实施例中由于凹槽6和柔性电路板2分设在导光板1沿其厚度方向的异面上,而柔性电路板2上的正负极导电件8与其对应的光源3的正负极相接触,因此,光源3的正负极与凹槽6不在导光板1的一侧,在将光源3与柔性连接板7连接的过程中,可以避免柔性连接板7将光源3的正负极覆盖,使光源3的正负极与柔性电路板2上的正负极导电件8能够更好的接触。另外,将光源3放入光源安装孔5中后,光源3能够将导光板1入光面盖住,而使光源3发出的光全部进入导光板1内部,有效防止光源3发出的光部分从导光板1的入射面反射,而造成入射光的泄露。
上述实施例中提到的光源3优选为发光二极管,由于发光二极管所发出的光色域更广,色彩表现能力更好,因此,采用发光二极管作为光源3的背光模组能够实现更好的发光效果。
本发明实施例还提供了一种液晶显示装置,包括上述技术方案所提的背光模组。采用上述技术方案所提的背光模组,进入导光板1的光背光灰度及均齐性均良好,因此,采用这种背光模组的液晶显示装置能够实现更好的显示效果。
上述实施例提供的液晶显示装置具体可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框或导航仪等任何具有显示功能的产品或部件。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应以所述权利要求的保护范围为准。
