背景技术
彩色滤光片是某些显示器，例如液晶显示器中实现彩色显示的关键元件，彩色滤光片是一种表现颜色的光学滤光片，它可以精确选择欲通过的小范围波段光波，反射或吸收掉其他不希望通过的波段的光波。目前的彩色滤光片上通常包括黑色遮光区域、RGB(红绿蓝)三基色区域。黑色遮光区域用于阻挡光的透过，RGB三基色区域包括红色区域、绿色区域以及蓝色区域，每三个区域构成一个像素，根据需要选择三个区域中的一个或多个透过光线显示该区域的颜色，从而三个区域混合成相应的颜色。目前的彩色滤光片的制程一般为通过光阻涂布→预烘烤→曝光→显影→后烘烤的方式依次分别形成黑色遮光区域、RGB三基色区域。该种制程较为复杂，制程时间长。此外，通过该种制程得到的彩色滤光片中，RGB三基色区域会比黑色遮光区域厚，导致后续彩色滤光片与液晶显示面板中的其他层的压合过程中容易出现问题。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述 中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的明显变形方式。
图1为本发明一实施例中的彩色滤光片的制造方法的流程图。
图2为本发明一实施例中的渗透膜形成于玻璃基板上的示意图。
图3为图1所示的方法中的一步骤的较佳实施例的子流程图。
图4-图7为本发明一较佳实施例中的彩色滤光片的形成过程示意图。
图8为本发明一实施例中的显示器的模块示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
请参阅图1及图2，图1为一种彩色滤光片100的制造方法的流程图。首先，在如图2所示的一玻璃基板10上形成一渗透膜20，并对该渗透膜20进行烘干处理(S101)。其中，该渗透膜20为一多孔结构的高分子渗透膜，可通过粘贴的方式形成于该玻璃基板10上。在其他实施例中，通过在该玻璃基板10涂布一层多孔结构的高分子渗透材料，而在玻璃基板10上形成该渗透膜20。其中，该渗透膜10形成于玻璃基板10的整个表面上。
然后，在该烘干的渗透膜20上依次且唯一覆盖具有镂空区域L1的黑色掩膜板Y1(如图4所示)、具有镂空区域L2的红色掩膜板Y2(如图5所示)、具有镂空区域L3的绿色掩膜板Y3(如图6所示)、具有镂空区域L4的蓝色掩膜板Y4(如图7所示)中的一个，并依次将覆盖有掩膜板的渗透膜20放入对应颜色的颗粒溶液而形成具有黑色遮光区域Z1、红色区域R1、绿色区域G1以及蓝色区域B1的彩色滤光片100(如图7所示)(S102)。
请一并参阅图3-7，图3为步骤S102在一较佳实施方式中的子流程图。在该烘干后的渗透膜20上贴覆如图4所示的具有镂空区域L1的黑色掩膜板Y1，并将贴覆有黑色掩膜板Y1的玻璃基板10放入碳黑颗粒溶液中而在渗透膜20上形成如图3所示的黑色遮光区域Z1以及标记区域M1(S1021)。其 中，黑色掩膜板Y1在需要形成黑色遮光区域B1以及标记区域M1的位置镂空成镂空区域L1其中，黑色掩膜板Y1中的镂空区域L1由于没有遮盖，从而炭黑颗粒溶液将会被烘干后的渗透膜20吸收而在该些镂空区域L1形成黑色图案，黑色图案不透光而形成黑色遮光区域B1以及该标记区域M1。该黑色掩膜板Y1中的镂空区域L1根据彩色滤光片100中需要形成黑色遮光区域B1以及标记区域M1的位置预先进行设置。其中，在本实施方式中，该标记区域M1对应的镂空位置为具有一定宽度的矩形边框。
去除黑色掩膜板Y1，并将如图5所示的具有镂空区域L2的红色掩膜板Y2根据标记区域M1贴覆在玻璃基板10上，并将具有贴覆有红色掩膜板Y2的渗透膜20的玻璃基板10放入红色颗粒溶液中而形成红色区域R1(S1023)。其中，该红色掩膜板R1的大小与标记区域M1的外框相同，将红色掩膜板R1与该标记区域M1的外框边对齐然后贴覆在该玻璃基板10上，然后再放入红色颗粒溶液中。红色掩膜板R1中的镂空的区域由于没有遮盖，从而红色颗粒溶液将会被烘干后的渗透膜20吸收而在该镂空的区域形成红色图案，该些红色图案而形成红色区域R1。其中，该红色掩膜板Y2中的镂空区域根据彩色滤光片100中需要形成红色区域R1的位置预先进行设置。
去除红色掩膜板Y2，并将如图6所示的具有镂空区域L3的绿色掩膜板Y3根据标记区域M1贴覆玻璃基板10上，并将具有贴覆有绿色掩膜板Y3的渗透膜20的玻璃基板10放入绿色颗粒溶液中而形成绿色区域G1(S1025)。其中，绿色掩膜板Y3的大小与该标记区域M1的外框边形成的区域相同，将绿色掩膜板Y3与该标记区域M1的外框边对齐然后贴覆在该玻璃基板10上的渗透膜20上，然后再放入绿色颗粒溶液中。绿色掩膜板Y3中的镂空区域L3由于没有遮盖，从而绿色颗粒溶液将会被烘干后的渗透膜20吸收而在镂空区域L3形成绿色图案，该些绿色图案形成绿色区域G1。其中，该绿色掩膜板Y3中的镂空区域L3根据彩色滤光片100中需要形成绿色区域G1的位置预先进行设置。
去除绿色掩膜板Y3，并将如图7所示的具有镂空区域L4的蓝色掩膜板Y4根据标记区域M1贴覆在玻璃基板10上，并将具有贴覆有蓝色掩膜板Y4的渗透膜20的玻璃基板10放入蓝色颗粒溶液中而形成蓝色区域B1，从而得 到了具有红色区域R1、绿色区域G1、蓝色区域B1以及黑色遮光区域Z1的彩色滤光片100(S1027)。其中，蓝色掩膜板Y4的大小与该标记区域M1形成的区域的外框大小相同，将蓝色掩膜板Y4与该标记区域M1的外框边对齐然后贴覆在该玻璃基板10上，然后再放入蓝色颗粒溶液中。蓝色掩膜板Y4中的镂空区域L4由于没有遮盖，从而蓝色颗粒溶液将会被烘干后的渗透膜20吸收而在镂空区域L4形成蓝色图案，蓝色图案形成蓝色区域B1。其中，该蓝色掩膜板Y4中的镂空区域L4根据彩色滤光片100中需要形成蓝色区域B1的位置预先进行设置。
其中，图3中所示的具体形成黑色遮光区域Z1、红色区域R1、绿色区域G1及蓝色区域B1的方法步骤仅仅是本发明一较佳实施方式。在其他实施方式中，该黑色遮光区域Z1、红色区域R1、绿色区域G1及蓝色区域B1的顺序可以调整为其他顺序。例如，通过红色掩膜板Y2首先在渗透膜20上形成红色区域R1及红色的标记区域M1，然后再依次通过黑色掩膜板Y1掩盖并放入黑色颗粒溶液中形成黑色遮光区域、通过蓝色掩膜板Y4掩盖并放入蓝色颗粒溶液中形成蓝色区域B1、以及通过绿色掩膜板Y3进行掩盖并放入绿色溶液中形成绿色区域G1。只是说，作为形成标记区域M1的第一个掩膜板的尺寸需与玻璃基板10的尺寸一致，后续的掩膜板的尺寸需与标记区域M1的外框大小一致即可。
其中，上述的黑色掩膜板Y1、红色掩膜板Y2、绿色掩膜板Y3、蓝色掩膜板Y4为在相应区域镂空的金属掩膜板，非镂空区域的位置均为金属材料板。
本发明的彩色滤光片100，由于通过干燥的渗透膜20去吸收对应的颜色颗粒而形成黑色遮光区域Z1、红色区域R1、绿色区域G1及蓝色区域B1。因此，本发明中的黑色遮光区域Z1、红色区域R1、绿色区域G1及蓝色区域B1均为该渗透膜20的不同位置直接染色而形成，因此厚度相同。
因此，本发明的彩色滤光片100包括该玻璃基板10、形成于玻璃基板上的通过相应的区域吸收黑色颗粒、红色颗粒、绿色颗粒以及蓝色颗粒而形成黑色遮光区域Z1、红色区域R1、绿色区域G1及蓝色区域B1的渗透膜20。如图7所示，在本实施方式中，该些红色区域R1、绿色区域G1、蓝色区域B1以及黑色遮光区域Z1为长条形区域，且最终形成的彩色滤光片100中，红色 区域R1、黑色遮光区域Z1、绿色区域G1、黑色遮光区域Z1、蓝色区域B1、黑色遮光区域Z1从左至右循环布置。显然，在其他实施方式中，该些红色区域R1、绿色区域G1、蓝色区域B1以及黑色遮光区域Z1可为其他形状的区域，其分布位置也可以为其他合适的分布方式。
请参阅图8，为本发明的显示器300的示意图。该显示器300包括显示面板200，该显示面板200包括上述的彩色滤光片100。该显示面板200可为液晶显示面板，显然该显示面板200还可以包括其他元件，例如TFT阵列基板、ITO电极层等。该显示器300可为液晶显示器。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
