背景技术
现有技术中,6代及以上的液晶显示面板中的TAC基材是平光的,可视角度相对较少,另外,在太阳光直射或在外界光线较强的情况下,因光线反射致使显示屏的表面出现晕光现象,显示屏的内容完全无法被人眼所观察,因此有必要予以改进。
发明内容
针对现有技术存在的不足,本发明的目的是提供一种防反射AG液晶显示面板,本发明结构简单,易于加工,加工效率高,生产成本低,。
为了实现上述目的,本发明所采用的技术方案是:一种防反射AG液晶显示面板,从上到下依次包括一个厚度小于50纳米的二氧化钛膜层、一个厚度小于3微米的AG膜层、一个厚度为150-200微米的SRF基材、一个厚度小于30微米的PSA光学粘着胶和一个厚度小于100微米的光学透明离型膜;SRF基材的表层具有一磨砂面,磨砂面相对均匀分布有平均粒径为20-100纳米的凹坑;表面经过高压电晕处理的SRF基材具有相对均匀分布的微型孔穴,微型孔穴深入SRF基材的深度为30-50纳米,微型孔穴的顶部的平均宽度为30-50纳米,SRF基材的表面的表面交错分布有凹坑和微型孔穴。
所述SRF基材的表面同时具有相对独立存在的所述凹坑、相对独立存在的所述微型孔穴以及由局部重叠的凹坑和微型孔穴所组成的组合型穴坑。其中,相对独立存在的所述凹坑间隔分布各所述微型孔穴之和所述组合型穴坑间的间隙中,且相对独立存在的微型孔穴间隔分布在各凹坑和组合型穴坑间的间隙中。所述二氧化钛膜层复合在SRF基材的表面,二氧化钛膜层封闭各所述微型孔穴的表面,二氧化钛膜层覆盖各所述凹坑。
本发明和现有技术相比所具有的优点是:本发明结构简单,易于加工,加工效率高,生产成本低,将外界的强光进行散光处理,将光线反射到四面八方,实现漫反射,其雾度小于0.63%,可见光透过率为大于93%,表面硬度为5H,对可见光的反射率小于0.63%。

图中:
具体实施方式
对比例一
一种漫反射显示面板,图1和2所示,从上到下依次包括,
第一层为PE保护膜层,保护膜为实际的使用层,避免脏污、刮花等,
第二层为AG硬化的光学涂层,实现漫反射的目的,
第三层为承载光学涂层的载体光学PET膜,
第四层为PSA光学粘着胶,便于与产品进行无缝隙粘着,
第五层为光学透明离型膜,保护膜光学粘着胶不收污染等。
对比例一的漫反射显示面板是三层普通膜系漫反射结构,其雾度为6.5%,透过率为92.5%,表面硬度为3H,像素值:250ppi,对可见光的平均反射率为1.5-2.2%。
图1和2所示,对可见光的反射率达1.5以上,在黑屏状态(未点亮)下以及在显示状态(点亮)下,通观察到的液晶显示面板中的灯管都是刺眼的,灯管影像对图像影响严重。
实施例一
一种防反射AG液晶显示面板,图3至6所示,从上到下依次包括一个厚度小于50纳米的二氧化钛膜层、一个厚度小于3微米的AG膜层、一个厚度为150-200微米的SRF基材、一个厚度小于30微米的PSA光学粘着胶和一个厚度小于100微米的光学透明离型膜;SRF基材的表层具有一磨砂面,磨砂面相对均匀分布有平均粒径为20-100纳米的凹坑;表面经过高压电晕处理的SRF基材具有相对均匀分布的微型孔穴,微型孔穴深入SRF基材的深度为30-50纳米,微型孔穴的顶部的平均宽度为30-50纳米,SRF基材的表面的表面交错分布有凹坑和微型孔穴;二氧化钛膜层复合在SRF基材的表面,二氧化钛膜层封闭各微型孔穴的表面,二氧化钛膜层覆盖各凹坑。
较佳的,二氧化钛膜层的厚度为15-18纳米、AG膜层的厚度为小于1微米、SRF基材的厚度为160-170微米的、PSA光学粘着胶的厚度为5-8微米和光学透明离型膜的厚度为70-80微米。
SRF基材的表面同时具有相对独立存在的凹坑、相对独立存在的微型孔穴以及由局部重叠的凹坑和微型孔穴所组成的组合型穴坑。相对独立存在的凹坑间隔分布各所述微型孔穴之述组合型穴坑间的间隙中,且相对独立存在的微型孔穴间隔分布在各凹坑和组合型穴坑间的间隙中。
本发明将外界的强光进行散光处理,将光线反射到四面八方,实现漫反射,而不是向一个方向反射。将一个方向反射的光变成多个方向反射的光,从而实现漫反射,防眩光膜可以有效减少来自屏幕55%的眩光和65%的反射,同时减少70%的有害蓝光和光泽度。使用防炫光膜可以减少蓝光损伤和眼睛眩光不适的风险,防止视觉疲劳和保护眼睛健康。
图3和4所示,对可见光的反射率降低至0.63以下,在黑屏状态(未点亮)下观察到的液晶显示面板中的灯管是散开且明显柔和的,在显示状态(点亮)下观察到的液晶显示面板灯管影像明显减轻且散开。
具体的,本发明的雾度为0.63%,透过率为93.5%,表面硬度为5H,像素值:250ppi,对可见光的反射率小于0.63,参见表1反射率测试。
Figure BDA0004136369760000041
表1反射率测试
具体的,相邻两个微型孔穴的平均间距为100-300纳米,相邻两个凹坑的平均间距为50-100纳米。较佳的,凹坑的平均粒径控制31-35纳米的,微型孔穴深入SRF基材的深度为5-10纳米,微型孔穴的顶部的平均宽度为41-45纳米,微型孔穴深入SRF基材的深度为31-35纳米,相邻两个微型孔穴的平均间距为260-280纳米,相邻两个凹坑的平均间距为80-90纳米,按数量占比30%以上的凹坑和对应的微型孔穴组成组合型穴坑。图5中黑色圆形区对应微型孔穴,白色和灰色的圆形凹陷对应不同深度的凹坑,本发明对波长380-420um的可见光的反射率从2.0491%线性下降至0.629%。本发明对波长420-460um的可见光的反射率从0.629%线性下降至0.4481%。本发明对波长460-620um的可见光的反射率为0.229至0.4481在该波长区间的可见光的反射率变化平缓变化。本发明对波长620-740um的可见光的反射率从0.229增长到2.736。
