以下将结合具体实施例及附图对本发明提供的阵列基板、液晶显示面板及显示装置进行详细描述。
请参阅图1，本发明提供一种显示装置1000，所述显示装置1000包括显示面板1001及主体1002，所述显示面板1001设置在所述主体1002内。
在本实施例中，所述显示装置1000可以是显示屏、笔记本、计算机等。所述显示面板1001可以是液晶显示面板、OLED显示面板、LED显示面板、Micro-LED显示面板、Mini-LED等显示面板。
请参阅图2，所述显示面板1001包括显示基板110及偏光片120，所述偏光片120形成在所述显示基板110上。所述偏光片120包括偏光主体121及形成在所述偏光主体121上的防眩减反射层130，所述偏光主体121位于所述显示基板110和所述防眩减反射层130之间。
在本实施例中，所述显示基板110可以是液晶显示基板、OLED显示基板、LED显示基板、Micro-LED显示基板、Mini-LED基板等中的至少一种。
在本实施例中，所述偏光主体121包括补偿膜(图未示)、偏光层(图未示)及保护层(图未示)，所述补偿膜形成在所述显示基板110上，所述偏光层形成 在所述补偿膜上，所述保护层形成在所述偏光层上，所述防眩减反射层130形成在所述保护层上，所述保护层为所述防眩减反射层130的基材。其中，所述补偿膜的材料可以是环烯烃聚合物(Cyclo Olefin Polymer，COP)、三醋酸纤维素(Tri-cellulose Acetate，TCA)等材料，例如所述补偿膜的材料可以为商品名为SANUQI的COP材料、商品名分别为PK3和NR01的TCA材料。所述偏光层的材料可以是聚乙烯醇(polyvinyl alcohol vinylalcohol polymer，PVA)等具有偏光作用的材料，所述保护层的材料可以是TCA、聚甲基丙烯酸甲酯(polymethyl methacrylate，简称PMMA)、聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，PET)等材料。
在其他实施例中，所述偏光片120的结构并不局限于上述结构，可以根据实际情况进行调整。
请再次参阅图2及图3，所述防眩减反射层130包括硬化层20、第一消光粒子层30及第二消光粒子层40。所述第一消光粒子层30包括多个第一消光粒子31，所述第二消光粒子层40包括多个第二消光粒子41，所述第一消光粒子31及所述第二消光粒子41均分散在所述硬化层20中。其中，所述第二消光粒子层40位于所述第一消光粒子层30和所述偏光主体121之间，所述第一消光粒子31的平均折射率小于所述第二消光粒子41的平均折射率。
在本发明一可选实施例中，所述第一消光粒子31的平均折射率为1.17～1.30。所述第二消光粒子41的平均折射率为1.65～1.85。
其中，基于反射光的干涉原理，光线入射到具有不同折射率的所述第一消光粒子31和所述第二消光粒子41的表面会发生干涉相消，可以降低所述防眩减反射层130的反射率，从而提升所述防眩减反射层130的减反射效果，提升所述显示面板1001的显示画面质量。
其中，可以通过压花等工艺分别自所述硬化层20相背的两表面将所述第一消光粒子31和所述第二消光粒子41压进所述硬化层20内，也可以改进所述第一消光粒子31和所述第二消光粒子41并将所述第一消光粒子31和所述 第二消光粒子41分散在制作所述硬化层20的材料中，再通过涂布等方式形成所述硬化层20。
在本发明一可选实施例中，所述第一消光粒子31的一部分位于所述硬化层20内，另一部分凸出于所述硬化层20的远离所述偏光片120的表面，以在所述硬化层20的远离所述偏光片120的表面上形成粗糙表面，所述粗糙表面使得所述防眩减反射层130的雾度得到提升，光线会在所述防眩减反射层130的表面发生漫散射，可以提升所述防眩减反射层130的防眩光效果，从而提升所述显示面板1001的显示画面质量。
在本发明一可选实施例中，所述第一消光粒子层30中的所述第一消光粒子31均匀分布且大小均一，以使得所述防眩减反射层130整体的防眩减反射效果均一，可避免出现局部反射光和眩光强烈的现象，可以进一步提升所述显示面板1001的显示画面质量。
在本发明一可选实施例中，所述第一消光粒子31呈球形。
在本发明一可选实施例中，定义所述第一消光粒子31凸出于所述硬化层20远离所述偏光片120的表面的部分的高度为H，则H满足：2/3R≤H<2R，其中，R为所述第一消光粒子31的粒径的一半。其中，H满足：2/3R≤H<2R可以使得所述防眩减反射层130具有较好的雾度。
在本发明一可选实施例中，所述第一消光粒子31的表面张力小于所述第二消光粒子41的表面张力。如此，可以使得所述第一消光粒子31上浮至所述硬化层20的远离所述偏光片120的一侧且部分凸出于所述硬化层20，并使得所述第二消光粒子41沉淀至所述硬化层20的面向所述偏光片120的一侧，有利于在所述硬化层20内形成具有不同折射率且层级分明的第一消光粒子层30和第二消光粒子层40。
具体地，在本发明一可选实施例中，所述第一消光粒子31的表面接枝有含氟的硅烷偶联剂，所述含氟的硅烷偶联剂可以降低所述第一消光粒子31的表面张力，不仅可以使得所述第一消光粒子31上浮至所述硬化层20的表层并 形成低反射层，还可以使得第一消光粒子31的表面和所述硬化层20具有更好的相容性，减少所述防眩减反射层130膜面的颗粒感。
在本发明一可选实施例中，所述第一消光粒子31可以为实心消光粒子或中空消光粒子或介孔消光粒子等。其中，所述实心消光粒子的折射率大于所述中空消光粒子的平均折射率且大于所述介孔消光粒子的平均折射率。
在本发明一可选实施例中，所述中空消光粒子的中空度在30％～60％之间，在这一范围内的中空度有利于所述中空消光粒子的光学性能和机械性能的平衡。
具体地，本发明引入中空度概念用以度量中空消光粒子的中空程度和平均折射率。
其中，所述中空消光粒子的中空度X的计算公式为：X＝V r/V R。其中，V r＝3πr 3/4为所述中空消光粒子的中空体积；V R＝3πR 3/4为所述中空消光粒子的整体体积。
其中，所述中空消光粒子的平均折射率为n＝n 0X+n 1(1-X)。其中，X为所述中空消光粒子的中空度，n 0为空气的折射率，n 1为实心的消光粒子的折射率，1.42≤n 1≤1.46，1.17≤n 0≤1.30。
其中，所述中空消光粒子可以通过喷雾干燥法、模板合成法等方法制备。
在本发明一可选实施例中，所述介孔消光粒子的内部具有粒径在2nm～50nm之间的孔隙。
在本发明一可选实施例中，所述第一消光粒子31的粒径在纳米级。具体地，所述第一消光粒子31的粒径在40nm～65nm之间。根据已有的研究理论可知：当颗粒的尺寸在4μm以下时，颗粒的散射强度较佳，因此，将所述第一消光粒子31的粒径尺寸按如上(40nm～65nm)设置，可以使得所述第一消光粒子31具有较佳的散射强度，从而能够提升所述防眩减反射层130的防眩光和减反射效果，从而提升所述显示面板1001的显示画面质量。
理论上所述防眩减反射层130的计算反射率公式为：
Figure PCTCN2022078624-appb-000001
式中，R为反射率，n 0为入射光所在介质折射率(空气折射率为1)，n 1为第一层(本发明的所述第一消光粒子31)的折射率，n 2为第二层(本发明的所述第二消光粒子41)的折射率，d为所述第一消光粒子31的粒径，λ为入射光波长。经过推算，理论上当d满足公式n 1d＝kλ/4时，所述第一消光粒子31的反射率最低。方程化为：
Figure PCTCN2022078624-appb-000002
因此，在设计低反层结构(所述第一消光粒子130)的粒径时，就可以基于该公式(n 1d＝kλ/4)进行计算。
具体地，在本发明一可选实施例中，所述第一消光粒子31为SiO 2等低折射率的消光粒子。更具体地，所述第一消光粒子31为实心SiO 2粒子或中空SiO 2粒子或介孔SiO 2粒子等。更具体地，所述第一消光粒子31为表面接枝有含氟的硅烷偶联剂的实心SiO 2粒子或中空SiO 2粒子或介孔SiO 2粒子等。
请参阅图3，在本发明一可选实施例中，所述第一消光粒子31包括中空部分311及实体部分312，所述中空部分311位于所述实体部分312的内部。所述实体部分312具有一远离所述中空部分311的外表面3121。
在本发明一可选实施例中，所述第一消光粒子31的外表面3121为平滑表面。
具体地，在本发明一可选实施例中，所述第一消光粒子31的外表面3121为圆形或椭圆形表面。
请参阅图4及图5，在本发明一可选实施例中，所述第一消光粒子31包括中空部分311及实体部分312，所述中空部分311位于所述实体部分312的内部。所述实体部分312具有一远离所述中空部分311的外表面3121，在本 发明一可选实施例中，所述第一消光粒子31的外表面3121为不规则表面。所述实体部分312的不规则的外表面3121包括多个凸部313和多个凹部314，所述凸部313和所述凹部314交替设置。
在本发明一可选实施例中，所述第一消光粒子31的外表面3121为不规则表面。通过引入粒子表面不规则的中空的二氧化硅作为第一消光粒子31，可以进一步加强粗糙表面的细微变化，外部环境光入射时，会在不规则结构上发生各种漫反射，以改变整体光路，从而增强了所述硬化层20表面的雾度，达到防眩膜的效果。
请再次参阅图4，在本发明一可选实施例中，所述凸部313包括第一平面3131和第二平面3132，所述第一平面3131和所述第二平面3132连接且构成一尖角。其中一个凸部313的第一平面3131与与之相邻的另一个凸部313的第二平面3132连接以形成所述凹部314。
请再次参阅图5，在本发明一可选实施例中，所述凸部313包括一圆弧面3133，相邻的两个所述凸部313的所述圆弧面3133的一端相交连接以形成所述凹部314。

在本发明一可选实施例中，所述第二消光粒子41为金属氧化物粒子。具体地，所述第二消光粒子41为氧化锌粒子、氧化钛粒子、氧化锡粒子等金属氧化物粒子。
在本发明一可选实施例中，所述第二消光粒子41为纳米级粒子。在本实施例中，所述第二消光粒子41为氧化锌纳米粒子、氧化钛纳米粒子、氧化锡纳米粒子等金属氧化物纳米粒子。具体地，所述氧化锌粒子的折射率为1.9、所述氧化钛粒子的折射率为2.1～2.3及所述氧化锡粒子的折射率为1.9。
在本发明一可选实施例中，所述第二消光粒子41的粒径范围在10nm～50nm之间。
在本发明一可选实施例中，所述第二消光粒子41的表面接枝有硅烷偶联剂。其中，所述硅烷偶联剂的分子结构式一般为Y-R-Si(OR) 3，其中，Y为有机官能基，SiOR为硅烷氧基，硅烷氧基对无机物具有反应性，有机官能基对有机物具有反应性或相容性。因此,当硅烷偶联剂介于无机和有机界面之间，可形成有机基体-硅烷偶联剂-无机基体的结合层。典型的硅烷偶联剂有A151(乙烯基三乙氧基硅烷)、A171(乙烯基三甲氧基硅烷)、A172(乙烯基三(β-甲氧乙氧基)硅烷)等。
通过硅烷偶联剂处理所述第二消光粒子41可以增加所述第二消光粒子41的表面张力，使得所述第二消光粒子41沉淀到所述硬化层20的底部并形成高折射层；如此，有利于在所述硬化层20内形成具有不同折射率且层级分明的第一消光粒子层30和第二消光粒子层40。
在本发明一可选实施例中，所述硬化层20的材质为丙烯酸树脂、聚氯乙烯树脂、水性聚氨酯树脂、紫外光固化树脂等中的至少一个。

在本实施例中，所述复合树脂为紫外光固化树脂。
其中，采用复合树脂作为所述硬化层20的材料一方面，可以使得所述防眩减反射层130具有较佳的消光效果，另一方面，由复合树脂所制作的硬化层20具有较好的硬度。
请参阅图7，当光线L1自外界射入凸出于所述硬化层20的所述第一消光粒子上，一部分光线L1和L2在所述第一消光粒子31的表面发生漫反射。可以提升所述防眩减反射层的防眩光效果，从而提升所述显示面板的显示画面质量。另一部分光线L3在所述第二涂层223内部发生折射和反射并产生第一反射光线L31和折射光线L32，所述折射光线L32入射到所述第二消光粒子41 表面并在所述第二消光粒子41表面发生反射，产生第二反射光线L33。基于反射光的干涉原理：光线入射到不同折射率的粒子或涂层会发生干涉相消，由于本发明提供的所述第一消光粒子31的折射率小于所述第二消光粒子41的折射率，故，所述第一反射光线L31与所述第二反射光线L33之间会发生干涉相消，从而能够降低所述光线L3在所述第一消光粒子31表面的反射光，以降低所述第一消光粒子31的反射率，从而提升所述防眩减反射层130的减反射效果，以提升所述显示面板1001的显示画面质量。部分光线L4和L5进入所述硬化层20内并在所述第二消光粒子41的表面发生漫反射，部分光线L5进入所述硬化层20内并在所述第二消光粒子41的内表面发生多次折射，能够将显示面板发出的光线打散，起到扩大视角的效果。部分光线L6进入所述硬化层20内并在所述第二消光粒子41内部发生折射。部分光线L7自所述第一消光粒子31和所述第二消光粒子41的空隙穿过所述硬化层20。
