本申请提供一种彩色滤光模组，用于大尺寸显示面板上，该大尺寸显示面板采用曝光接图方式实现大屏，该彩色滤光模组结构使得该大尺寸显示面板的显示亮度均匀。
参照图1和图2，图1为本申请提供的彩色滤光模组的结构示意图；图2为图1中A-A的剖面结构示意图；所述彩色滤光模组包括至少两个彩色滤光片10，所述彩色滤光片10相互拼接，其中，所述彩色滤光片10包括：
基板100，所述基板100即为玻璃衬底；
遮光膜200，所述遮光膜200也叫黑色矩阵，其作用是遮挡住显示面板中的液晶层的杂乱散射光，防止亚像素之间混色和防止环境光照射到薄膜晶体管（TFT）沟道。本实施例中所述遮光膜200间隔设置在所述基板100上，每块彩色虑光片上的所述遮光膜200的间距固定不变，每块所述遮光膜200之间的间隙可以相同，也可以根据需求设置不同。
以及彩膜300，所述彩膜300也即红/绿/蓝三基色阻，色阻的作用是吸收自然光中的一部分光谱，仅透过与之匹配的单色光谱，形成混色中的基色。所述彩膜300间隔设置在所述遮光膜200之间，且部分与所述遮光膜200重叠，也即所述彩膜300设置在所述遮光膜200的间隙中，且部分延伸至所述遮光膜200上，所述彩色滤光片10上的彩膜300与所述遮光膜200重叠的部位为重叠区400。
显示面板实现大尺寸设置，基于采用至少两块相互拼接的彩色滤光片10形成，若两块相互拼接的彩色滤光片10上彩膜300与遮光膜200的重叠区400差别过大，则显示面板的亮度显示会出现不均匀情况，本实施例至少设置相邻两个彩色滤光片10相对位置处的重叠区400的尺寸差值小于预设值，如此所形成的彩色滤光模组在大尺寸的显示面板中，保证显示面板的显示亮度均匀，其中，所述预设值为光透过相邻两个彩色滤光片10时满足亮度时，所述重叠区400允许的最大尺寸差值。
本申请中，相邻两个彩色滤光片10相对位置处的重叠区400的尺寸差值可以为重叠区400的重叠区400面积差值，保证透过彩色滤光模组同一位置处的亮度均匀；相邻两个彩色滤光片10相对位置处的重叠区400的尺寸差值也可以为所述重叠区400在遮光膜200排列方向的长度差值，通过控制两个相邻彩色虑光片上的所述重叠区400在遮光膜200排列方向的长度差值小于预设值，基于所述遮光膜200和彩膜300在其延伸方向的长度一定，在保证其排列方向的长度差值小于预设值时，确保其重叠区400面积的差值小于预设值，故设置所述重叠区400在遮光膜200排列方向的长度差值小于预设值时，即可实现透过彩色滤光模组同一位置处的同一位置亮度均匀。
设置相邻两个彩色滤光片10对应位置处的重叠区400的尺寸差值小于预设值，例如，彩色滤光片10上设有四排遮光膜200时，从左到右分别标记为1号遮光膜200、2号遮光膜200、3号遮光膜200和4号遮光膜200，遮光膜200之间设置彩膜300，部分所述彩膜300与遮光膜200重叠，设置1号遮光膜200的右侧与彩膜300重叠的重叠区400为第一重叠区400，相邻两个彩色滤光片10拼接时，设置其第一重叠区400的长度差值小于预设值，也即a-b的绝对值小于预设值，以使光通过相邻两个彩色滤光片10的第一重叠区400位置时，相邻两个彩色滤光片10的第一重叠区400照射到显示屏上的显示亮度均匀。
可选的，也可以设置所述彩色滤光片10各个重叠区400之间的尺寸差值小于预设值，也即彩色滤光片10上所有重叠区400之间的尺寸差值小于预设值，例如，彩色滤光片10上设有四排遮光膜200时，从左到右分别标记为1号遮光膜200、2号遮光膜200、3号遮光膜200和4号遮光膜200，遮光膜200之间设置彩膜300，部分所述彩膜300与遮光膜200重叠，设置1号遮光膜200的右侧与彩膜300重叠的重叠区400为第一重叠区400，设置2号遮光膜200的右侧与彩膜300重叠的重叠区400为第二重叠区400，相邻两个彩色滤光片10拼接时，设置其第一重叠区400的长度差值小于预设值，同时设置所述第一重叠区400与第二重叠区400的尺寸差值小于预设值，以使光通过相邻两个彩色滤光片10的各个重叠区400位置时，照射到显示屏上的显示亮度均匀。
在本申请提供的彩色滤光模组包括至少两个彩色滤光片10，所述彩色滤光片10相互拼接，以形成大彩色滤光模组，基于彩色滤光片10上的彩膜300与遮光膜200存在部分重叠，通过设置相邻两个彩色滤光片10相对位置处的重叠区400的尺寸差值小于预设值，使得透过相邻两个彩色滤光片10的光差距较小，使得经过所述彩色滤光模组照射到显示屏上的显示亮度均匀。
可选地，所述预设值为1.2um-1.7um。也即设置相邻两个彩色滤光片10相对位置处的重叠区400的长度差值小于1.2um到1.7um。本实施例设置所述预设值设有1.5um，设置所述长度差值小于1.5um，以使透过相对位置处的光差异较小，提高显示面板的显示均匀度。
一实施例中，基于上述彩色滤光片10，所述彩色滤光片10还可以包括平坦层（图中未标注），所述平坦层设置所述彩膜300之上，所述平坦层设置的目的在于在遮光膜200和彩膜300（红/绿/蓝三基色阻）的段差之间形成一个平坦面，有利于液晶的取向，同时隔离彩膜300中的重金属杂质与取向层接触而污染液晶。
可选地，所述彩色滤光片10还可以包括隔垫物，所述隔垫物设置在所述平坦层上，所述隔垫物呈柱状，用于维持液晶盒厚，所述隔垫物包括主隔垫物和辅助隔垫物，所述主隔垫物与所述辅助隔垫物间隔设置。
在一般设置中，相邻彩膜300的相对面为倾斜面301，所述倾斜面301位于所述彩膜300与所述遮光膜200的重叠位置，也即彩膜300与遮光膜200的互叠区设置呈斜坡。在示例性技术中，由于彩膜300的材料特征原因需要设置该倾斜面301长且缓，对于长且缓的倾斜面301，斜面较薄的位置容易落入遮光膜200的开口区，若彩膜300较薄的位置落入遮光膜200的开口区时，容易出现该开口区的显示亮度不均匀的情况，故本申请设置所述倾斜面301与所述基板100的夹角c为60度-90度，具体通过改变彩膜300材料的特性或在彩膜300制程过程中，缩短所述彩膜300的显影时间，以使相邻彩膜300的相对面的倾斜面301的倾斜角c度在60度-90度之间。
由于倾斜面301与基板100的角度设置为60度-90度之间，倾斜面301较为陡峭，彩膜300的厚薄位置被遮光膜200遮挡，不容易落入遮光膜200的开口区，从而避免出现显示亮度不均匀的问题出现。本实施例中，所述倾斜面301与所述基板100的夹角c为70度，基于遮光膜200之间的间隙固定不变，所述倾斜面301与所述基板100的夹角c为70度时，保证彩膜300的透光作用的同时，更佳程度确保彩膜300的厚薄区不会落入遮光膜200的开口区。
一实施例中，参照图3，本申请还提供一种彩色滤光模组的制作方法，所述彩色滤光模组至少包括两个彩色滤光片，所述彩色滤光片相互拼接，其中，所述彩色滤光模组的制作方法包括以下步骤：
S10，在基板上间隔形成遮光膜；
所述基板为玻璃衬底，在所述玻璃衬底上形成遮光膜。具体在所述玻璃衬底上涂布遮光材料，涂布遮光材料后进行曝光处理，将景观曝光处理的遮光膜进行显影，形成所需求的BM图案（遮光膜图案），形成所述彩色滤光模组的遮光膜。
S20，在所述遮光膜之间形成彩膜，所形成的彩膜与所述遮光膜部分重叠，其中，所述彩色滤光片上的彩膜与所述遮光膜重叠的部位为重叠区，在所述遮光膜之间形式所述彩膜时，设置相邻的两个彩色滤光片相对位置处的重叠区的尺寸差值小于预设值。
其中，相邻两个彩色滤光片相对位置处的重叠区的尺寸差值可以为重叠区的重叠区面积差值，保证透过彩色滤光模组同一位置处的亮度均匀；相邻两个彩色滤光片相对位置处的重叠区的尺寸差值也可以为所述重叠区在遮光膜排列方向的长度差值，通过控制两个相邻彩色虑光片上的所述重叠区在遮光膜排列方向的长度差值小于预设值，基于所述遮光膜和彩膜在其延伸方向的长度一定，在保证其排列方向的长度差值小于预设值时，确保其重叠区面积的差值小于预设值，故设置所述重叠区在遮光膜排列方向的长度差值小于预设值时，即可实现透过彩色滤光模组同一位置处的同一位置亮度均匀。
所述预设值为1.2um-1.7um。也即设置相邻两个彩色滤光片相对位置处的重叠区的长度差值小于1.2um到1.7um。本实施例设置所述预设值设有1.5um，设置所述长度差值小于1.5um，以使透过相对位置处的光差异较小，提高显示面板的显示均匀度。
具体在所述遮光膜上形成所述彩膜之前，先测量相邻两个彩色滤光片相对位置处的遮光膜的尺寸，根据所述遮光膜的尺寸以及所在位置确定彩膜的位置，进而在所述位置形成所述彩膜，使得相邻的两个彩色滤光片相对位置处的重叠区的尺寸差值小于预设值。
在彩色滤光模组制作过程中，通过在形成彩膜之前，预先确定相邻两个彩色滤光片相对位置处的遮光膜尺寸，以及相对基板的位置，根据所述遮光膜尺寸和位置确定彩膜的位置，以使相邻的两个彩色滤光片相对位置处的重叠区的尺寸差值小于预设值，基于此所形成的彩色滤光模组，使得透过相邻两个彩色滤光片的光差距较小，使得经过所述彩色滤光模组照射到显示屏上的显示亮度均匀。
可选地，参照图4，所述在所述遮光膜之间形成彩膜的步骤包括：
S210，在所述遮光膜上涂布彩膜；
S211，对所述彩膜进行曝光处理；
S212，对经过曝光处理的彩膜进行显影，且缩短显影时间，以使彩膜的倾斜面与基板的夹角c为60度-90度。
由于彩色滤光模组具有红/绿/蓝三基色阻，在所述遮光膜上形成所述彩膜的过程中，需分别对各个色阻分别进行涂布、曝光和显影处理，如在所述遮光膜上涂布红色阻层，对红色阻层进行曝光处理，对经过曝光处理的红色阻层进行显影，且缩短显影时间，以使红色阻层的倾斜面与基板的夹角c为60度-90度；再在所述遮光膜上涂布绿色阻层，对绿色阻层进行曝光处理，对经过曝光处理的绿色阻层进行显影，且缩短显影时间，以使绿色阻层的倾斜面与基板的夹角c为60度-90度；最后在所述遮光膜上涂布蓝色阻层，对蓝色阻层进行曝光处理，对经过曝光处理的蓝色阻层进行显影，且缩短显影时间，以使蓝色阻层的倾斜面与基板的夹角c为60度-90度。
在更佳实施例中，对经过曝光处理的彩膜进行显影时，缩短显影时间，以使彩膜的倾斜面与基板的夹角c为70度。
本申请在形成彩膜的过程中，通过缩短显影的时间，使得所述彩膜之间相对的面形成倾斜面，且该倾斜面与基板的夹角c为60度-90度之间，基于倾斜角度较大，该倾斜面较陡峭，彩膜的厚薄位置不易落入遮光膜的开口区，有效的防止接图时显示亮度不均匀的问题出现。
一实施例中，参照图1和图5，本申请还提供一种显示面板，所述显示面板包括：
阵列基板1002以及彩色滤光模组1，所述彩色滤光模组1与所述阵列基板1002间隔设置；
所述彩色滤光模组1包括至少两个彩色滤光片10，所述彩色滤光片10相互拼接，其中，所述彩色滤光片10包括：
基板100；所述基板100即为玻璃衬底；
遮光膜200，所述遮光膜200也叫黑色矩阵，其作用是遮挡住显示面板中的液晶层的杂乱散射光，防止亚像素之间混色和防止环境光照射到薄膜晶体管（TFT）沟道。本实施例中所述遮光膜200间隔设置在所述基板100上，每块彩色虑光片上的所述遮光膜200的间距固定不变，每块所述遮光膜200之间的间隙可以相同，也可以根据需求设置不同。
以及彩膜300，所述彩膜300也即红/绿/蓝三基色阻，色阻的作用是吸收自然光中的一部分光谱，仅透过与之匹配的单色光谱，形成混色中的基色。所述彩膜300间隔设置在所述遮光膜200之间，且部分与所述遮光膜200重叠，也即所述彩膜300设置在所述遮光膜200的间隙中，且部分延伸至所述遮光膜200上，所述彩色滤光片10上的彩膜300与所述遮光膜200重叠的部位为重叠区400。
显示面板实现大尺寸设置，基于采用至少两块相互拼接的彩色滤光片10形成，若两块相互拼接的彩色滤光片10上彩膜300与遮光膜200的重叠区400差别过大，则显示面板的亮度显示会出现不均匀情况，本实施例至少设置相邻两个彩色滤光片10相对位置处的重叠区400的尺寸差值小于预设值，如此所形成的彩色滤光模组1在大尺寸的显示面板中，保证显示面板的显示亮度均匀，其中，所述预设值为光透过相邻两个彩色滤光片10时满足亮度时，所述重叠区400允许的最大尺寸差值。
本申请中，相邻两个彩色滤光片10相对位置处的重叠区400的尺寸差值可以为重叠区400的重叠区400面积差值，保证透过彩色滤光模组1同一位置处的亮度均匀；相邻两个彩色滤光片10相对位置处的重叠区400的尺寸差值也可以为所述重叠区400在遮光膜200排列方向的长度差值，通过控制两个相邻彩色虑光片上的所述重叠区400在遮光膜200排列方向的长度差值小于预设值，基于所述遮光膜200和彩膜300在其延伸方向的长度一定个，在保证其排列方向的长度差值小于预设值时，确保其重叠区400面积的差值小于预设值，故设置所述重叠区400在遮光膜200排列方向的长度差值小于预设值时，即可实现透过彩色滤光模组1同一位置处的同一位置亮度均匀。
设置相邻两个彩色滤光片10对应位置处的重叠区400的尺寸差值小于预设值，例如，彩色滤光片10上设有四排遮光膜200时，从左到右分别标记为1号遮光膜200、2号遮光膜200、3号遮光膜200和4号遮光膜200，遮光膜200之间设置彩膜300，部分所述彩膜300与遮光膜200重叠，设置1号遮光膜200的右侧与彩膜300重叠的重叠区400为第一重叠区400，相邻两个彩色滤光片10拼接时，设置其第一重叠区400的长度差值小于预设值，也即a-b的绝对值小于预设值，以使光通过相邻两个彩色滤光片10的第一重叠区400位置时，相邻两个彩色滤光片10的第一重叠区400照射到显示屏上的显示亮度均匀。
可选的，也可以设置所述彩色滤光片10各个重叠区400之间的尺寸差值小于预设值，也即彩色滤光片10上所有重叠区400之间的尺寸差值小于预设值，例如，彩色滤光片10上设有四排遮光膜200时，从左到右分别标记为1号遮光膜200、2号遮光膜200、3号遮光膜200和4号遮光膜200，遮光膜200之间设置彩膜300，部分所述彩膜300与遮光膜200重叠，设置1号遮光膜200的右侧与彩膜300重叠的重叠区400为第一重叠区400，设置2号遮光膜200的右侧与彩膜300重叠的重叠区400为第二重叠区400，相邻两个彩色滤光片10拼接时，设置其第一重叠区400的长度差值小于预设值，同时设置所述第一重叠区400与第二重叠区400的尺寸差值小于预设值，以使光通过相邻两个彩色滤光片10的各个重叠区400位置时，照射到显示屏上的显示亮度均匀。
所述显示面板还包括液晶，所述液晶设置在所述阵列基板1002与所述彩色滤光模组1之间，所述液晶位于背离所述基板100的一侧。
在本申请提供的显示面板包括彩色滤光模组1，其中彩色滤光模组1包括至少两个彩色滤光片10，所述彩色滤光片10相互拼接，以形成大彩色滤光模组1，基于彩色滤光片10上的彩膜300与遮光膜200存在部分重叠，通过设置相邻两个彩色滤光片10相对位置处的重叠区400的尺寸差值小于预设值，使得透过相邻两个彩色滤光片10的光差距较小，使得经过所述彩色滤光模组1照射到显示屏上的显示亮度均匀。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的构思下，利用本申请说明书及附图内容所作的等效变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
