Description

一种背光模组、显示面板及显示装置 技术领域
本申请涉及显示面板技术领域,尤其涉及一种背光模组、显示面板及显示装置。
背景技术
LCD显示器是目前显示领域中最为常见的显示器,由于其自身轻薄低能耗和较低的价格深受消费者的喜爱,但是目前传统白背光与色阻的相结合使得LCD显示器的色域一直处于劣势。量子点是近年来最受人们关注的发光材料之一,它的发光峰集中,色纯度高,并且可以通过调节量子点的成分和尺寸等方式来改变发光的波段位置,目前已有大量产品将量子点应用于LCD显示器中来提升显示器自身的色域。
其中作为普遍的是将量子点的树脂体系通过挤压成型的方式制得量子点增亮膜,将量子点增量膜放置在LCD显示器的背光单元中。由于目前量子点材料中红绿量子点的合成已经很成熟,且荧光量子产率较高,以硒化镉CdSe量子点为例,其荧光量子产率可达90%以上。但是蓝色量子点由于尺寸小、稳定性差、荧光量子产率低等因素很难在产品中得到应用,所以一般产品是以蓝背光为背光源,激发红绿混合的量子点增亮膜后混合得到白光,由于蓝光LED的发光峰也集中,所以使蓝色量子点的应用变得不那么重要。
但是,由于量子点是点光源,其类似于发光的球体,故其被激发的红色量子点发出的红色与绿色的光型很大,而蓝色LED受LED自身设计的限制光型很小,从而在红绿蓝混合的白光进入LCD面板前,红光、绿光光型与蓝光光型差异较大,从而在观看视角变大时,受光型影响,红绿光衰减慢,而蓝光衰减较快,从而导致大视角偏黄问题。
因此,确有必要来开发一种新型的背光模组,以克服现有技术的缺陷。
技术问题
本发明的一个目的是提供一种背光模组,其能够解决现有技术中量子点液晶显示面板存在的红光、绿光光型与蓝光光型差异较大,从而在观看视角变大时,受光型影响,红绿光衰减慢,而蓝光衰减较快,从而导致大视角偏黄的问题。
技术解决方案
为实现上述目的,本发明提供一种背光模组,包括LED光源;量子点增亮膜,设于所述LED光源的一侧;其中,所述量子点增亮膜含有蓝色荧光粉和红绿量子点的树脂体系。

将蓝色荧光粉与红绿量子点混合制得新型量子点树脂体系,再通过挤压成型的方式制得量子点增亮膜,背光采用紫外或近紫外LED激发,激发蓝色荧光粉和红绿量子点发射红绿蓝三色光,红绿蓝三色出射光型一致,从而解决了红绿蓝三色光型的差异问题,从而达到改善大视角色偏的问题。
进一步的,在其他实施方式中,其中所述蓝色荧光粉采用BaMgAl14O23:Eu 、BaMg2Al16O27:Eu、 Al7O3N5:Eu中的一种或多种组合。
进一步的,在其他实施方式中,其中所述红绿量子点采用CdSe、ZnCdSe2、InP,Cd2Sse、Cd2SeTe、InAs中的一种或多种组合。
蓝色荧光粉可充当扩散粒子的作用,增加紫外光光程,防止量子点团聚,可以起到提高紫外光利用率,从而提高量子点增亮膜中量子点的光效;进一步地,蓝色荧光粉发射的蓝光可以再次激发红绿量子点,可进一步提升量子点光效。
进一步的,在其他实施方式中,其中所述背光模组还包括反射片,设于所述LED光源远离所述量子点增亮膜的一侧。
