Description
技术领域
本发明属于液晶显示器配件领域,更具体的说涉及一种液晶显示器背板。
背景技术
液晶显示技术是在两块导电玻璃面板之间充满液晶材料,在外加电压作用下,液晶分子会发生扭转,使得背光源的光线透过液晶材料,再经过三色滤色片进行成像。液晶显示技术有多种类型,其中薄膜晶体管液晶显示技术最为常用,其是以液晶为介质、以薄膜晶体管为控制元件的集大规模半导体集成电路技术和平板光源技术于一体的显示技术。
现有技术中,液晶显示因其具有平板化、低功耗、无闪烁、使用寿命长等许多优点而被广泛应用。液晶显示器从-30℃到80℃的温度范围内都可以正常使用,既可作移动显示终端、台式显示终端,还可以用于壁挂式超大屏幕电视。总之,液晶显示器件具有诸多优点,而且随着材料、光源技术和半导体工艺技术的同步发展,目前正逐步向集成化、智能化、经济化方向发展。
虽然液晶显示器在设计技术、产业链和工艺流程方面都已经比较成熟,但是随着液晶显示器的使用和技术的发展,人们对液晶显示在产品的优化设计、性能提升和成本控制上提出了更高的要求。然而液晶显示由于它属于被动显示技术,其本身不能发光,必须要有背光源。所以,液晶显示器的重要性能指标如画质、色彩再现性、亮度、对比度、功耗、厚度、成本等都会与液晶显示器的背板上的背光源密不可分。可以说,液晶显示器的很多重要性能都是由背光源所控制的。
发明内容
本发明的目的在于提供一种液晶显示器背板,通过优化背板上的背光源,实现对液晶显示器的画质、色彩再现性、亮度、对比度、功耗、厚度、成本进行控制和优化,使得液晶显示器能够满足人们日益提高的要求。
本发明技术方案一种液晶显示器背板,包括依次设置的背板、主控制板、光源板、导光板、扩散板、电路板、垂直偏光板、后玻璃基板、液晶、彩色滤光板、前玻璃基板、水平偏光板和面板,所述光源板外部设置有混光区,所述导光板设置在混光区口部。
优选地,所述混光区包括设置在所述光源板四周的挡光板,所述挡光板内侧面上覆有反射膜。
优选地,所述光源板包括光源底板,所述光源底板上固定有反射片和若干灯条,所述灯条与光源底板固接。
优选地,所述灯条包括铝制灯条底板和均布固定在铝制灯条底板上的若干LED灯珠,所述光源底板为铝板,所述铝板四周卡接有PCD板。
优选地,所述混光区内灯条前端设置有量子点玻璃管,所述量子点玻璃管前端为导光板。
优选地,所述量子点玻璃管为在玻璃管内封装红色量子点材料和绿色量子点材料。
优选地,所述玻璃管横截面为方形,且与混光区横截面相适应,所述量子点玻璃管两端及距离混光区内侧面较近的一对侧面均通过热熔胶与混光区内侧面固定。
优选地,所述导光板与混光区内侧面固定。
本发明技术方案的一种液晶显示器背板的有益效果是:
1、设置混光区,实现将光源进行集中,使得光源能够全部的从导光板上射出,避免光源有光源板周边泄露,影响背板整体质量和对光源的控制。
2、设置量子点玻璃管,加强液晶模组的背光效果,从而改善了液晶显示器的色域。
附图说明
图1为本发明技术方案的一种液晶显示器背板结构示意图,
图2为本发明技术方案的一种液晶显示器背板中光源板结构示意图。
具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细的说明。本发明的实施例是为了示例和描述起见而给出的,而并不是无遗漏的或者将本发明限于所公开的形式。很多修改和变化对于本领域的普通技术人员而言是显而易见的。选择和描述实施例是为了更好说明本发明的原理和实际应用,并且使本领域的普通技术人员能够理解本发明从而设计适于特定用途的带有各种修改的各种实施例。
如图1和图2所示,本发明技术方案一种液晶显示器背板,包括依次设置的背板1、主控制板2、光源板3、导光板4、扩散板5、电路板6、垂直偏光板7、后玻璃基板8、液晶9、彩色滤光板10、前玻璃基板11、水平偏光板12和面板13。光源板3外部设置有混光区35,导光板4设置在混光区35口部。利用混光区实现对光源板3上发出的光进行反射和阻隔,避免光线溢出。
如图2所示,混光区35包括设置在光源板3四周的挡光板32,挡光板32内侧面上覆有反射膜。放射膜实现将照射在其上的光线进行反射至混光驱,最终全部进入导光板4并由导光板4均匀射出。
如图2所示,光源板3包括光源底板31,光源底板31上固定有反射片33和若干灯条34,灯条34与光源底板31固接。安装时,首先将反射片33安装在光源底板31,然后将灯条34用过反射片33固定在光源底板31上。反射片33实现对灯条34发出的光线进行反射,有效的降低灯条34的密度和灯条上灯珠的密度,减小灯珠和灯条的使用,降低成本,同时也能够减少热源和也降低灯珠发热量。
如图2所示,灯条34包括铝制灯条底板和均布固定在铝制灯条底板上的若干LED灯珠,光源底板为铝板,铝板四周卡接有PCD板。采用铝板作为光源底板31,提高其散热效果和散热速度,避免灯珠工作发热对整个背板造成影响。
如图2所示,混光区35内灯条34前端设置有量子点玻璃管36,量子点玻璃管36前端为导光板4。量子点玻璃管36为在玻璃管内封装红色量子点材料和绿色量子点材料。玻璃管横截面为方形,且与混光区横截面相适应,量子点玻璃管36两端及距离混光区35内侧面较近的一对侧面均通过热熔胶与混光区35内侧面固定。导光板4与混光区内31侧面固定。设置量子点玻璃管,加强液晶模组的背光效果,从而改善了液晶显示器的色域。
上述技术方案中,从灯条34中发射出来的光线经过量子点玻璃管36,再通过导光板,可以把这些点光源转变成一个均匀分布的面光源,同时将光线从正面透射出来,再利用扩散板等光学膜片将光线均匀的发散出去,加强液晶模组的背光效果,从而改善了液晶显示器的色域。
显然,所描述的实施例仅仅是本发明的一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域及相关领域的普通技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例,都应属于本发明保护的范围。本发明中未具体描述和解释说明的结构、装置以及操作方法,如无特别说明和限定,均按照本领域的常规手段进行实施。
