实施例1
参照图1、图2，本实施例提供了一种滤光片1，其包括介质层11以及设置于介质层11上的线栅层12，线栅层12上设置有线栅结构阵列，线栅结构阵列包括多个线栅结构12a，图2示出了线栅层12包括一个线栅结构12a的情况，每个线栅结构12a包括第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123，第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123分别包括多个间隔设置的线栅100，其中，第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123的栅距均不相 等，由于第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123的栅距不相等，入射光经过第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123滤光后得到四种不同的颜色的光。
介质层11为折射率调制的多层介质结构，优选的，介质层11包括第一折射率调制层110、设置于第一折射率调制层110上的第二折射率调制层111以及设置于第二折射率调制层111与线栅层12之间的第三折射率调制层112。其中，第一折射率调制层110与第三折射率调制层112的折射率低于第二折射率调制层111，第一折射率调制层110与第三折射率调制层112的材质可以为SiO2、SiO、MgO等，第二折射率调制层111的材质可以为Si3N4、TiO2、Ta2O5等。
具体的，第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123的栅距依次减小。线栅层12包括线栅结构阵列及黑矩阵单元12b，黑矩阵单元12b位于第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123之间，黑矩阵单元12b不透光，其用于防止第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123的侧面漏光。每个线栅单元中的线栅100的宽度以及栅距相等，不同线栅单元的栅距不相等。线栅层12的材质为具有较大折射率虚部的材料，例如为铝、银或金等，优选的，线栅层12的材质为铝。
其中，第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123中的线栅周期为200nm～500nm，这里线栅周期指的是两个相邻的线栅100的几何中心之间的距离，线栅100的宽度为线栅周期的0.4～0.9倍，线栅100的高度为20nm～200nm。线栅100为条状，其沿与与介质层11及线栅100垂直的方向上的截面的形状为方形、梯形或三角形，不同的线栅单元中的线栅100的长度相等。
通过改变每个线栅单元的栅距、线栅100的宽度、线栅100的高度以及线栅100的材质可以获得不同颜色的光的同时提升每个线栅单元的透光率。
参照图3，本实施例还提供了一种显示装置，其包括背光模组2以及依次设置于背光模组2上的下基板、液晶层3以及上基板，上基板包括基底4以及位于基底4上的上偏光片5，下基板包括下偏光片6、上述的滤光片1以及TFT阵列7，TFT阵列7位于下偏光片6上，滤光片1位于TFT阵列7与液晶层3之间，线栅层12 位于介质层11与液晶层3之间。其中，上偏光片5的偏振方向与下偏光片6的偏振方向垂直，背光模组2为侧入式背光模组结构或者直下式背光模组结构。当背光模组2发出的光入射到线栅层12上时，入射到黑矩阵单元12b和线栅100上的光被吸收，其余入射光从每个线栅单元中两个相邻的线栅100之间穿过并通过第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123分别对其进行滤光后得到颜色为红色的R子像素、颜色为绿色的G子像素、颜色为蓝色的B子像素以及颜色为白色的W子像素，例如，第一线栅单元120对入射光进行滤光后得到R子像素，第二线栅单元121对入射光进行滤光后得到G子像素，第三线栅单元122对入射光进行滤光后得到B子像素，第四线栅单元123对入射光进行滤光后得到W子像素，这样入射光通过每个线栅结构12a便可以得到R、G、B以及W这四个子像素，这四个子像素形成显示装置的一个像素。
参照图4，优选的，本实施例显示装置中的线栅层12的材质为铝，第一线栅单元120中的线栅周期为400nm～500nm，第二线栅单元121中的线栅周期为300nm～450nm，第三线栅单元122中的线栅周期为200nm～350nm，第四线栅单元123中的线栅周期为200nm～500nm。通过这样的设置可以使得第一线栅单元120在红光波段对应的中心峰值处的透过率、第二线栅单元121在绿光波段对应的中心峰值处的透过率以及第三线栅单元122在蓝光波段对应的中心峰值处的透过率分别大于70％，而在波段外的最低透过率低于10％；第四线栅单元123在全波段的透过率大于70％。其中，位于任意两个相邻的第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123之间的黑矩阵单元12b的宽度相等。
除此之外，本实施例的显示装置还包括OC平坦化层8，其位于线栅层12与液晶层3之间，OC平坦化层8覆盖于线栅层12的上表面，用于增加线栅层12的上表面的平滑性以及对液晶层3起到防污染的作用。
本实施例每个线栅结构12a中的第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123的排列方式可以根据实际显示需要进行设定，图3中只是通过示例给出并不用于进行限定。
下面以线栅层12的材质为铝，线栅层12的高度固定的情况为例来具体描述通过改变每个线栅单元的栅距、线栅100的宽度使得R子像素、G子像素和B子像 素合成的白光色坐标与W子像素的白光色坐标相匹配的过程。
参照图5，整个匹配过程包括以下步骤：
步骤S1、选取使得第一线栅单元120在红光波段对应的中心峰值处的透过率大于70％、在波段外的最低透过率低于10％的第一参数范围，第二线栅单元121在绿光波段对应的中心峰值处的透过率大于70％、在波段外的最低透过率低于10％的第二参数范围，第三线栅单元122在蓝光波段对应的中心峰值处的透过率大于70％、在波段外的最低透过率低于10％的第三参数范围，第四线栅单元123在可见光对应的全波段的透过率大于70％的第四参数范围。这里的参数包括线栅单元的线栅周期和占空比，其中，占空比表示的是线栅100的宽度与线栅周期的比值。
步骤S2、在第一、第二、第三参数范围中选取不同的参数，计算R子像素、G子像素和B子像素在选取的参数下合成的白光色坐标在不同灰阶下的色坐标变化曲线，从而得到R子像素、G子像素和B子像素在第一、第二、第三参数范围下的第一色坐标变化曲线集合。
步骤S3、在第四参数范围中选取不同的参数，计算W子像素在选取的参数下的白光在不同灰阶下的色坐标变化曲线，从而得到W子像素在第四参数范围下的第二色坐标变化曲线集合。
步骤S4、选取第一色坐标变化曲线集合与第二色坐标变化曲线集合中偏差最小的两个色坐标变化曲线所对应的参数作为第一线栅单元120、第二线栅单元121、第三线栅单元122以及第四线栅单元123的线栅参数，从而实现R子像素、G子像素和B子像素合成的白光色坐标与W子像素的白光色坐标相匹配。
通过改变每个线栅单元的栅距、线栅的宽度、线栅的高度以及线栅的材质可以获得不同颜色的光的同时提升每个线栅单元的透光率，此外，还可以使得R子像素、G子像素和B子像素合成的白光色坐标与W子像素的白光色坐标相匹配，从而改善显示装置的白点漂移现象。
实施例2
参照图6，本实施例与实施1的不同之处在于，滤光片1位于TFT阵列7与下 偏光片6之间，线栅层12位于介质层11与TFT阵列7之间。
本实施例的显示装置除了具备实施例1中的显示装置的性能外，通过将滤光片1设置于TFT阵列7与下偏光片6之间，可以省去实施例1的显示装置中的OC平坦化层8，通过TFT阵列将滤光片1与液晶层3进行隔离，避免了线栅层12对液晶层3产生污染。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
