具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
请参阅图1,本发明实施例一提供的显示面板20与蓝色背光模组10相对层叠设置,蓝色背光模组10发出蓝色的背光源进入液晶面板后使液晶面板显示彩色图像信息,用于用户通过人眼接收。一种实施方式中,显示面板20为液晶显示面板,液晶显示面板通过施加于液晶分子上的驱动电压的大小调节液晶分子的偏转角度,从而控制显示面板20显示的图像。
本发明实施例一提供的显示面板20包括第一基板22、液晶层26及第二基板24,液晶层26位于第一基板22与第二基板24之间,一种实施方式中,第一基板22为彩膜基板,第二基板24为阵列基板,第一基板22、液晶层26及第二基板24一次层叠设置并通过框胶密封后形成液晶盒。第一基板22提供公共电压,第二基板24提供像素电压,通过改变公共电压与像素电压的压差(即驱动电压)调 节液晶分子的偏转角度。
结合图2,第一基板22包括阵列排布的红色子像素222、绿色子像素224及蓝色子像素226,红色子像素222用于发出红色的光线,绿色子像素224用于发出绿色的光线,蓝色子像素226用于发出蓝色的光线,通过控制红、绿、蓝三原色光线的亮暗与搭配可以显示任意的彩色图像。
本实施例中,红色子像素222填充有红色量子点,绿色子像素224填充有绿色量子点。一种实施方式中,红色量子点和绿色量子点为量子点(Quantum Dots,QDs)材料,量子点材料能够将高能区的背光源(本实施例中为蓝色背光模组10提供的蓝色背光源)转换成可控的三色子像素,例如红色量子点将蓝色背光源转化为红色光线,绿色量子点将蓝色背光源转化为绿色光线。具体的,量子点材料本身具备光转换能力,在受到蓝色背光源激发的情况下,发生电子跃迁,而后以荧光辐射的形式完成电子空穴的复合,量子点材料作为典型的零维纳米材料,其各个方向都是在量子限域范围内的尺寸,因此荧光辐射也不存在方向选择性,故受激后的量子点材料是向360°无差别辐射荧光的,第一基板22发出的红色光线和绿色光线向各方向散射,可以有效平衡各视角亮度情况,大视角亮度与正视视角亮度的差异的梯度变化较缓和。一种实施方式中,红色量子点和绿色量子点材料体系为丙烯酸系、环氧类或聚烯烃类树脂。
本实施例中,蓝色子像素226填充有透明散射粒子2260,蓝色背光源照射至第一基板22的蓝色子像素226时,蓝色背光源穿过透明散射粒子2260并以蓝色光线向显示面板20外射出。具体的,蓝色背光源穿过透明散射粒子2260时蓝色光线被重新打散,光型被拓宽,形成向显示面板20外各方向散射的蓝色光线,同时搭配红色子像素222发出的红色光线、绿色子像素224发出的绿色光线的散射效果,从显示面板20发出的所有光线均覆盖较大的显示角度,最终实现改善视角表现的目的。
一种实施方式中,透明散射粒子2260包括无机纳米粒子和树脂微球,具体的,透明散射粒子2260包括TiO2,SiO2,ZnO等,树脂微球包括聚苯乙烯、聚甲基丙烯酸甲酯(PMMA)等。无机纳米粒子和树脂微球具有良好的透明度以提高蓝色背光源的透过率,并且使蓝色光线具有良好的散射效果。
一种实施方式中,透明散射粒子2260的直径为10nm~1um,以提高透明散 射粒子2260对蓝色背光源的散射效果。具体的,无机纳米粒子和树脂微球的直径均为10nm~1um,可选的,无机纳米粒子的直径为20nm、100nm、500nm或800nm,树脂微球的直径为30nm、80nm、300nm或900nm。
本实施例中,蓝色背光模组10位于第二基板24背离液晶层26的一侧并向显示面板20提供蓝色背光源。具体的,蓝色背光模组10通过蓝色发光二极管(Light Emitting Diode,LED)发出的蓝色光线依次穿过第二基板24和液晶层26后到达第一基板22,并使红色子像素222、绿色子像素224及蓝色子像素226分别发出散射的红色光线、绿色光线及蓝色光线。
蓝色背光模组10提供的蓝色背光源依次穿过第二基板24和液晶层26后照射到第一基板22,蓝色背光源激发红色量子点发射红色光线,蓝色背光源激发绿色量子点发射绿色光线,量子点材料产生的红色光线和绿色光线向显示面板20外各方向散射,蓝色背光源穿过透明散射粒子2260向显示面板20外发射蓝色光线,透明散射粒子2260重新打散蓝色背光源,光型被拓宽的蓝色光线搭配红色光线和绿色光线的散射效果,提高了液晶显示器大视角处显示亮度,大视角亮度与正视角亮度变化梯度缓和,平衡了各视角亮度,改善视角表现,提高用户体验。
本实施例中,显示面板20还包括第一偏光片282和第二偏光片284,第一偏光片282和第二偏光片284分别设置在液晶层26相对的两侧,并且第二偏光片284位于液晶层26与蓝色背光模组10之间。具体的,蓝色背光源经过第二偏光片284筛选后只剩下与第二偏光片284的偏振方向相同的蓝色光线通过,偏转的液晶分子调整该蓝色光线的偏振方向,并且仅有经过调整后与第一偏光片282的偏振方向相同的蓝色光线能够穿过第一偏光片282。
结合图3,本实施例中,红色子像素222、绿色子像素224及蓝色子像素226均包括入光口22a与出光口22b,入光口22a位于第一基板22面对液晶层26的一侧,出光口22b位于第一基板22背离液晶层26的一侧,入光口22a的尺寸大于出光口22b的尺寸。具体的,第一基板22的截面中,红色子像素222、绿色子像素224及蓝色子像素226的截面为梯形,红色子像素222和绿色子像素224中,红色量子点和绿色量子点受激发出的红色光线和绿色光线在梯形的斜边反射后从出光口22b射出,以提高显示面板20射出的红色光线和绿色光线的角度;蓝色 子像素226中,从入光口22a进入的蓝色光线在梯形的斜边反射后从出光口22b射出,以提高显示面板20射出的蓝色光线的角度。
一种实施方式中,第一基板22还包括黑色矩阵200,黑色矩阵200位于红色子像素222、绿色子像素224及蓝色子像素226之间。黑色矩阵200填充红色子像素222、绿色子像素224及蓝色子像素226之间的缝隙,用于遮挡显示面板20中的像素电极等不透明的元件。
请参阅图4,本发明实施例二提供的显示面板20与实施例一的区别在于,第一偏光片282位于第一基板22与液晶层26之间。具体的,蓝色光线在照射至第一基板22之前,蓝色光线已经过第一偏光片282和第二偏光片284的筛选和准直,从而使红色子像素222、绿色子像素224及蓝色子像素226接收的蓝色光线具有相同的偏振方向,并且入射方向较统一,一方面提高了红色量子点和绿色量子点的受激发光效果,另一方面有序的蓝色光线穿过透明散射粒子2260后散射效果较佳。
蓝色背光模组10提供的蓝色背光源依次穿过第二基板24和液晶层26后照射到第一基板22,蓝色背光源激发红色量子点发射红色光线,蓝色背光源激发绿色量子点发射绿色光线,量子点材料产生的红色光线和绿色光线向显示面板20外各方向散射,蓝色背光源穿过透明散射粒子2260向显示面板20外发射蓝色光线,透明散射粒子2260重新打散蓝色背光源,光型被拓宽的蓝色光线搭配红色光线和绿色光线的散射效果,提高了液晶显示器大视角处显示亮度,大视角亮度与正视角亮度变化梯度缓和,平衡了各视角亮度,改善视角表现,提高用户体验。
请参阅图5,本发明实施例三提供的显示面板20与实施例二的区别在于,第二偏光片284位于第二基板24背离液晶层26的一侧。具体的,蓝色背光源进入液晶盒前先经过第二偏光片284筛选准直,以使经过阵列基板的蓝色背光源有序,提高蓝色背光源的透过率,即提高蓝色背光源的利用率,降低能耗。
本发明实施例提供的显示面板20还包括透明盖板210,透明盖板210位于第一基板22背离液晶层26的一侧。一种实施方式中,透明盖板210贴合于第一基板22的表面。透明盖板210可以为玻璃或塑料等透明材料制成。透明盖板210用于保护显示面板20,以避免刮伤或损坏第一基板22。
蓝色背光模组10提供的蓝色背光源依次穿过第二基板24和液晶层26后照射到第一基板22,蓝色背光源激发红色量子点发射红色光线,蓝色背光源激发绿色量子点发射绿色光线,量子点材料产生的红色光线和绿色光线向显示面板20外各方向散射,蓝色背光源穿过透明散射粒子2260向显示面板20外发射蓝色光线,透明散射粒子2260重新打散蓝色背光源,光型被拓宽的蓝色光线搭配红色光线和绿色光线的散射效果,提高了液晶显示器大视角处显示亮度,大视角亮度与正视角亮度变化梯度缓和,平衡了各视角亮度,改善视角表现,提高用户体验。
