具体实施方式
以下各实施例的说明是参考附加的图式，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。
附图和说明被认为在本质上是示出性的，而不是限制性的。在图中，结构相似的单元是以相同标号表示。另外，为了理解和便于描述，附图中示出的每个组件的尺寸和厚度是任意示出的，但是本申请不限于此。
在附图中，为了清晰起见，夸大了层、膜、面板、区域等的厚度。在附图中，为了理解和便于描述，夸大了一些层和区域的厚度。将理解的是，当例如层、膜、区域或基底的组件被称作“在”另一组件“上”时，所述组件可以直接在所述另一组件上，或者也可以存在中间组件。
另外，在说明书中，除非明确地描述为相反的，否则词语“包括”将被理解为意指包括所述组件，但是不排除任何其它组件。此外，在说明书中，“在......上”意指位于目标组件上方或者下方，而不意指必须位于基于重力方向的顶部上。
为更进一步阐述本申请为达成预定发明目的所采取的技术手段及功效，以下结合附图及具体的实施例，对依据本申请提出的显示面板的制造方法及其制造装置，其具体实施方式、结构、特征及其功效，详细说明如后。
图1为范例性的混切产品和纯切产品的对比示意图。请参考图1，其中，上方的两图为纯切产品12(例如产品C，或产品D)，而下方一图则展示的是混切产品13，混切产品是相对于纯切产品来说的，简称MMG(Multi-Model on Glass)，在一个基板上设计并生产出不同的尺寸或规格的产品，MMG产品的基板利用率很高，减少浪费情况；可以设计出满足市场需求的不同尺寸的产品；降低成本。
MMG产品的困难是无法找到一个共享的制程参数，使两支产品的性能同时达到最佳。尤其是两支产品的开口率大小相差很多时(如图1，A和B的尺寸不一样，分辨率一样的话，A产品的像素开口率会远小于B产品的像素开口率)，在光配向技术条件下，同样的制程参数，由于A和B接收到的紫外光的照光量不同，形成的预倾角大小是不一样的，而预倾角直接影响产品的对比度和响应时间。和预倾角强相关的制程参数有：液晶的特性，紫外光的强度和照射时间，上下显示面板(CF板和array板)之间所加的电压差。
图2为范例性的混切产品的示意图，图中第一区域A和第二区域B对应的两支产品在相同的紫外光照射下，获得相同的紫外光照射强度，如此，将会形成相同的预倾角，即该PSVA(聚合物 稳定的垂直排列液晶，Polmer Stabilized Vertivally Aligned)产品，在形成预倾角时，紫外光是同时照光的，所获得的光强也都是一样的。
如此，若第一区域A和第二区域B对应的两支产品的预期预倾角不同的话，由于使用的是同一光源，而预倾角与显示面板获得的光强有关，这会使得显示面板形成的预倾角无法达到预期要求。
图3为本申请一实施例的一种显示面板的制造装置的示意图、图4为本申请一实施例的一种遮光板的示意图、图5为本申请一实施例的显示面板混切产品的制造示意图及图6为本申请一实施例的一种显示面板的制造方法的流程图。请参照图3、图4及图5，本申请一实施例中，一种显示面板的制造装置100，包括：一安装单元10，用于放置一基板11；一涂布单元20，用于涂布配向材料；一光源30，用于对所述基板11进行曝光显影以形成一配向层；一遮光板40(举例：液晶板)，设置在所述安装单元10和光源30之间，所述光线挡板40的透光率可控制；以及一切割单元50，用于对配向完成的所述基板11进行切割，得到多个显示面板。
在本申请的一实施例中，所述遮光板40(举例：液晶板)内设置有控制透光率的遮光图层41、42。
在本申请的一实施例中，所述遮光板40(举例：低反光材质的多重透光率板)内设置有控制透光率的遮光图层41、42。
在本申请的一实施例中，所述遮光板40(举例：液晶板)可拆卸或所述遮光图层41、42可更换。
在本申请的一实施例中，所述遮光板40(举例：低反光材质的多重透光率板)可拆卸或所述遮光图层41、42可更换。
在本申请的一实施例中，所述遮光板40(举例：液晶板)包括至少两个不同的区域，每个区域对应设置有不同透光率的遮光图层41、42。
在本申请的一实施例中，所述遮光板40(举例：低反光材质的多重透光率板)包括至少两个不同的区域，每个区域对应设置有不同透光率的遮光图层41、42。
在本申请的一实施例中，所述基板11为阵列基板，所述基板11组件包括配向层、主动开关与像素单元中至少其一所组成的群组。
在本申请的一实施例中，所述基板11为彩色滤光层基板，所述基板11组件包括配向层、遮光层与电极层中至少其一所组成的群组。
在本申请的一实施例中，一种显示面板的制造装置100，由于装配了控制透光率的遮光板40，因而同一个光源可以不必更换或者进行调整，而通过调整遮光板40的透光率以适应不同显示 面板的光照需求；而且，本申请的显示面板的制造装置100可以使用于纯切产品的制造，也可以用于混切产品，纯切产品时，可以进行光照强度的快速调整以满足需求，而混切产品，则能够在使用同一光源的情况下，让不同的显示面板，由于遮光板40的存在，而获得不同的光照强度，以形成预期的预倾角，这让混切产品在光照强度这一制程参数上得到很好的解决；本申请不仅使用范围广，而且能够让不同的显示面板都能够获得需求的光照强度，进而使产品的预倾角达到最佳，这大大提高了生产效率，而且能够减少材料的损耗，以及光源等相关设备的调整和改进成本，降低产品成本。
在本申请的一实施例中，所述遮光板40(举例：液晶板或低反光材质的多重透光率板)可以是做好一定的透光率而不可更改的，但是可以将遮光板40进行拆卸而换上不同的遮光板40以适应生产的要求；当然，该遮光板40也可以是通过加装遮光图层41、42等器件而实现透光率的调节的，这种情况下，该遮光图层41、42是可以更换的，根据不同的产品更换不同透光率、尺寸或者是形状的遮光图层41、42以适应不同的显示面板的生产需求；而且，该遮光板40可以设置一个或者多个遮光图层41、42。
在本申请的一实施例中，遮光板40(举例：液晶板或低反光材质的多重透光率板)包括至少两个不同的区域(可以包括图中，第一区域A和第二区域B)，每个区域对应设置有不同透光率的遮光图层(即图中对应区域A的第一遮光图层41和对应区域B的第二遮光图层42)。
在本申请的一实施例中，通过更换遮光板40(举例：液晶板或低反光材质的多重透光率板)或更换遮光图层41、42调整各个区域的尺寸和形状。该显示面板的制造装置100中，该遮光板40可以拥有多个不同的区域，该区域的尺寸大小与显示面板的尺寸大小相对应，以适应混切产品(同时进行两种以上显示面板的制造)的需求；并且该区域的尺寸大小、形状和透光率等都是可以调整的，例如，一种A产品较小，而同时的B产品较大，那么就可以设置光线挡板上拥有两种不同尺寸的区域；当然，该不同区域的透光率等也是和显示面板相对应的。
在本申请的一实施例中，基板11对应不同的显示面板划分为不同区域，所述遮光板40对应不同区域设置不同透光率的遮光图层41、42；所述遮光图层41、42的透光率对应显示面板的开口率进行设置，透光率的大小与显示面板的开口率成反比。本实施例中，实际上该遮光板40之所以设置成不同的区域，正式因为基板11上也是对应不同的显示面板划分了区域的，遮光板40对应区域以及区域中的显示面板进行设置和调整。
请参考图3及图6，在本申请的一实施例中，一种显示面板的制造方法，包括：提供一基板11，所述基板11上涂布组件成形材料，所述基板11上划分成多个组件成形区域；配置遮光板40于所述基板11与光源30之间，其中，所述遮光板40包括多个透光区域，所述多个透光区域位置分别对应所述多个组件成形区域，所述多个透光区域具有相同、相异或局部相同的透光率；对所 述基板11进行曝光显影；以及对所述基板11进行切割，得到多个显示面板；其中，所述光源30的光源30通过所述遮光板40而照射至所述基板11；所述基板11为阵列基板或彩色滤光层基板。
在本申请的一实施例中，每一透光区域包括：透光区、遮光区与半透光区，所述半透光区的透光率介于所述透光区和所述遮光区之间。
在本申请的一实施例中，所述遮光板的透光率依据低反光材质的掺入及分布密度而调节，使所述半透光区的透光率低于所述透光区的透光率，且高于所述遮光区的透光率。
在本申请的一实施例中，所述低反光材质的材质是选自于铬金属及其化合物所组成的群组。
在本申请的一实施例中，所述半透光区的透光率介于30％到70％。

本申请使混切产品(Multi-Model on Glass)设计的两支产品都得到最佳的预倾角。
“在一些实施例中”及“在各种实施例中”等用语被重复地使用。所述用语通常不是指相同的实施例；但它也可以是指相同的实施例。“包含”、“具有”及“包括”等用词是同义词，除非其前后文意显示出其它意思。
以上所述，仅是本申请的实施例，并非对本申请作任何形式上的限制，虽然本申请已以具体的实施例揭露如上，然而并非用以限定本申请，任何熟悉本专业的技术人员，在不脱离本申请技 术方案范围内，当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本申请技术方案的内容，依据本申请的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本申请技术方案的范围内。
