Description

背光模组及显示装置
本发明要求2015年6月26日递交的发明名称为“背光模组及显示装置”的申请号201510361769.0的在先申请优先权,上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及液晶显示技术领域,特别涉及一种背光模组及显示装置。
背景技术
液晶显示器是当今市场上的主流平板显示器技术。而显示器都需要背光来作为光源点亮液晶显示器。传统的背光模组包括LED组成的背光源,背光源的光线经过背光模组将光源转化成面光源射出,经过扩散片的匀光作用,从背光模组出射,经过液晶面板后即可显示出我们所需要的图像。随着科技的进步,人们对显示器的品质需求越来越高,高色域成为该领域内的一个热门话题。
现在市场上一种热点技术是采用量子点(quantum dot)改进背光色域,量子点是准零维的纳米材料,由少量的原子所构成;其粒径一般介于1~10nm之间,由于电子和空穴被量子限域,连续的能带结构变成具有分子特性的分立能级结构,受激后可以发射荧光,进而改变注入光的色域。
现有技术中一种常见的背光模组中采用量子管装于灯源与导光板之间,以改进液晶显示器的色域。但是量子管两端必然存在失效边缘,一般会将失效边缘伸入背光模组的胶框中,但是无效区域较长这样使得背光模组边框宽度增加,不利于窄边框设计。

具体实施方式
下面将结合本发明实施方式中的附图,对本发明实施方式中的技术方案进行清楚、完整地描述。
请参阅图1与图2,本发明提供一种背光模组及具有背光模组的显示装置。所述显示装置包括还包括盖于所述背光模组上的显示面板并通过双面胶114固定。本实施例中,所述背光模组包括胶框10、背光源11、导光板12、量子管13及光学薄膜14。所述导光板12包括入光面121及出光面122,所述背光源11包括基板111及数个呈直线排列于基板111上的灯源112,所述量子管13包括本体131及由本体131两端弯折形成的弯折段132,所述光学薄膜14装于所述出光面122上,所述胶框10围绕所述导光板12及光学薄膜14周缘设置,所述量子管13装于所述基板111上与所述数个灯源112平行设置,所述灯源112位于胶框10与导光板12之间,所述本体131位于所述灯源112与所述入光面121之间,所述本体131两端的弯折段132位于数个灯源112中位于两端的灯源112外侧。
请参阅图3,本实施例中,所述胶框10为矩形框体结构,其包括两个相对的边框101及连接两个边框101的侧框(图未标)。所述边框101及侧框围成收容空间,用以收容所背光源11、导光板12、量子管13及光学薄膜14。 所述背光模组还包括反光板15。所述反光板15装于所述胶框10一侧,所述导光板12设于所述反光板15上。具体的所述反光板15作为所述胶框10的底板,与胶框10形成矩形槽结构,用于承载导光板12并收容所述背光源11及量子管13。灯源112的线未进入导光板的部分或者从导光板12漏出的部分经反光板15反射回导光板12内,充分利用光源。
所述导光板12为矩形板体,用于收入灯源112的光线并均与后射出所述出光面。所述入光面121连接所述出光面122。所述入光面121为导光板112的一侧面。所述出光面边缘设有凸起部123。所述光学薄膜14为矩形板体,其叠加于所述出光面122上,所述凸起部123围绕所述光学薄膜14设置。所述基板111为铝基板,为所述灯源112提供电量。所述灯源112为LED灯,数个灯源112呈直线排列于所述基板111的一个表面上。
所述量子管13为截面呈矩形的玻璃管体。所述量子管13内的量子点的大小不完全相同却均匀分布。可以有大部分或者小部分量子点的大小相同。所述量子管13有较长的量子管基材剪切形成,所述弯折段132的自由端部为剪切端。所述弯折段132为所述本体131两端向同一方向弯折形成。本实施例中,弯折段132与本体131成直角设置。所述本体131平行于所述数个灯源112所在直线,所述弯折段132位于数个灯源112中位于两端的灯源112外侧,即数个灯源112中位于两端最外侧的灯源的外侧位置。当灯源112的光线经过入光面121进入所述量子管13的本体131后,在进入所述入光面121,经导光板12均匀光线后射出出光面122。所述量子管13改变注入光的色域,提高了背光模组出光的色域。
进一步的,所述本体131的长度与所述数个灯源112依次排列的总长度相同,及保证所述本体131与所述灯源112完全对应,进而实现灯源112的光纤完全进入所述本体131后在进入入光面121。由于所述弯折段132的自由端部为剪切端,由于量子管剪切边缘易受水氧等外界条件的影响,产生失效,所以弯折段132的自由端为失效部分,而所述弯折段132避开灯源设置,不会影响进入入光面121的光线的高色域,保证导光板的高色域光线;并且弯折段132位于所基板111内灯源112的侧部,不会伸出基板111,节省长度空间,避免增加背光模组边框宽度。本实施例中,所述量子管13通过模内注射成型。
进一步的,所述量子管13与所述基板111上设有灯源112的表面之间通过双面胶113固定。所述基板111两端相对量子管13设有卡持部115,所述本体131上靠近所述弯折段132的部分卡持于卡持部115内。具体的,所述本体131及弯折段132朝向相同的一侧面与所述基板111通过双面胶113固定。所述卡持部115为卡槽、夹爪或者扣环等可以稳固所述量子管的结构。
进一步的,所述基板111两端抵持所述边框101的表面上,所述基板111边缘通过双面胶与所述边框101固定。本实施例中,所述基板111的两端放于所述边框101的表面上。在其它实施方式,所述基板111两端插入所述边框101内与边框101固定,也就是说,所述基板111端部从所述胶框10内侧插入所述边框101内,如此结构节省胶框的宽度及背光模组的厚度。
本发明的显示装置为手机显示屏、显示器等电子设备。
本发明的背光模组采用量子管13设于灯源源入光面之间,量子管13因为空气等环境产生失效的部分设于弯折段132,避开入光面121,进而避免背光模组边缘失效问题,同时所述弯折段132位于灯源112的边缘,不占用二外的长度空间,避免增加胶框的宽度,便于实现窄边框设置。本发明的显示装置采用所述背光模组,可以避免边缘是小问题,而且便于窄边框的设计。
以上所述是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也视为本发明的保护范围。
