需要说明的是，本实施例中的“彩色光”不包括白光，彩色光例如包括红光、绿光和蓝光等。
需要说明的是，本公开实施例中“透明光学膜层的厚度”是指透明光学膜层在垂直于衬底的方向上的厚度。
需要说明的是，“视觉粗糙度”是指人眼感受到的图像(例如画作)表面的高低起伏的程度，其表征本公开实施例提供的显示面板所显示的图像模拟出的纸质画作的表面的粗糙度的效果。
本公开至少一实施例提供了一种显示基板。该显示基板包括：显示层、多个光学膜层形成单元和间隔层。显示层包括多个像素区，所述多个像素区的每个包括发出不同彩色光的多个彩色子像素开口；多个光学膜层形成单元与所述显示层堆叠设置；间隔层位于所述显示层与所述多个光学膜层形成单元之间以将所述显示层与所述多个光学膜层形成单元间隔开；所述多个光学 膜层形成单元构造为在所述间隔层的远离所述显示层的一侧形成透明光学膜层，所述透明光学膜层配置为使显示图像具有视觉粗糙度。
示意性地，参照图1A，该显示基板包括：衬底10、显示层22和多个光学膜层形成单元30。衬底10具有相对设置的第一表面11和第二表面12。显示层22设置在第一表面11上，且划分为多个像素区21(图中仅示出了一个像素区)，多个像素区21的每个包括发出不同彩色光的多个彩色子像素开口。例如，多个像素区的每个还包括黑矩阵211，黑矩阵211限定出多个子像素开口。例如，显示层22包括多个彩色滤光片212，多个彩色滤光片212分别设置在多个彩色子像素开口中；例如，多个彩色子像素开口中的彩色滤光片212分别为红色滤光片、绿色滤光片和蓝色滤光片，不同彩色光分别为红光、绿光和蓝光。多个光学膜层形成单元30与显示层22堆叠设置。例如，多个光学膜层形成单元30间隔设置在衬底10的第二表面12的远离显示层22的一侧，配置为在第二表面12的远离显示层22的一侧形成透明光学膜层40，透明光学膜层40配置为使显示图像具有视觉粗糙度。在本实施例中，衬底10配置为所述间隔层，衬底10位于显示层22与多个光学膜层形成单元30之间以将显示层22与多个光学膜层形成单元30间隔开，以使显示层22受到衬底10的保护。使采用该显示基板的显示面板用于显示图像时，例如该图像为画作，当画作的某处具有颜料堆叠的层次、凝固或者墨迹在纸张上干涸后的凹凸时，可控制光学膜层形成单元在第二表面上对应该位置处形成具有预定厚度的透明光学膜层，该预定厚度的透明光学膜层便可表现出画作中颜料堆叠的层次感、凝固感或者墨迹在纸张上干涸后的凹凸感等不同的画作立体质感，还原画作原始风格。例如，光学膜层形成单元利用透明有机材料或透明有机材料和溶剂形成该透明光学膜层。
例如，如图1A所示，透明光学膜层40在衬底10上的正投影可以覆盖一部分彩色子像素开口在衬底10上的正投影；透明光学膜层40在衬底10上的正投影也可以覆盖所有子像素开口在衬底10上的正投影，根据所需显示的画作进行控制。
例如，图1A所示的实施例中的显示基板为彩膜基板，可用于液晶显示装置(LCD)等。
根据本公开的实施例，光学膜层形成单元的数量没有要求，本领域技术人员可根据实际需求在多个像素区设置光学膜层形成单元。例如，在本公开至少一实施例中，光学膜层形成单元30和像素区21一一对应设置。当显示基板处于显示工作状态时，多个光学膜层形成单元30配置为形成多个所述透明光学膜层40，多个透明光学膜层40与多个像素区21一一对应。例如，多个透明光学膜层40的每个在显示层22上的正投影与多个像素区21中与其对应的一个至少部分重叠。例如，透明光学膜层40具有预定厚度。多个透明光学膜层40中的至少两个的厚度不同。由此，可以在任何不同的显示位置处形成光学膜层，根据每个像素区显示图像(例如画作)的颜料的数量、颜料堆叠的层次、凝固或者墨迹在纸张上干涸后的凹凸的具体情况，对应于多个像素区21形成不同预定厚度的光学膜层40，以满足对不同画作，以及不同位置设置光学膜层的需求。实体画作中，对画作的截面进行放大会发现，其表面的颜料不是完全平整的，而且还存在高低起伏，这些起伏形成了画作颜料的质感。这里的质感是指颜料材质带给人眼的视觉感受。以油画为例，不同的油画原料的堆叠形成起伏，这些材料及起伏形成油画的质感。在呈现该油画的电子画作中，通常，画面是用平整的像素显示的，每个像素间的高低起伏几乎不可被人眼察觉，即显示图像不具有视觉粗糙度。在本公开实施例提供的显示基板中，在显示层上增加具有预设厚度的透明的光学膜层来模拟纸质画作的颜料的质感和画作表面的起伏，以使显示图像具有视觉粗糙度。
例如，多个光学膜层形成单元30的每个在显示层22上的正投影与多个彩色子像素开口的每个不重叠，例如，多个光学膜层形成单元30的每个在衬底10上的正投影与多个彩色滤光片212的每个在衬底上的正投影不重叠。从而，光学膜层形成单元30不会影响多个彩色子像素开口中光的透过率，也就不会影响使用该显示基板的显示面板的显示效果。
例如，在本公开的一些实施例中，参照图1A，多个光学膜层形成单元30的每个在衬底10上的正投影在黑矩阵211在衬底10上的正投影范围内，即多个光学膜层形成单元30的每个在显示层22上的正投影位于黑矩阵211的范围内。在本公开的另一些实施例中，例如，显示基板的每个像素区211的多个子像素开口的每个还包括发出白光的白色子像素开口23，参照图1B 和图3，光学膜层形成单元30可设置在白色子像素开口23对应的位置，即白色子像素开口23在衬底10上的正投影与光学膜层形成单元30在衬底10上的正投影至少部分重叠，即多个光学膜层形成单元30的每个在显示层22上的正投影与白色子像素开口23至少部分重叠。当然，在存在白色子像素开口23的情况下，光学膜层形成单元30也可设置在黑矩阵211对应的位置，即黑矩阵211在衬底10上的正投影覆盖光学膜层形成单元在衬底10上的正投影(这种情况图未示出)。由此，光学膜层形成单元30不会影响进入彩色滤光片(非白色滤光片)的光的透过率，从而不会影响使用该显示基板的显示面板的显示效果。
例如，在另一个实施例中，如图2A所示，显示基板包括：衬底10、显示层22和多个光学膜层形成单元30。显示层22位于衬底10上；显示层22包括多个能够发射不同彩色光的多个彩色发光器件213，分别位于多个彩色子像素开口中；间隔层100位于多个彩色发光器件213的远离衬底10的一侧且覆盖多个彩色发光器件213，以保护多个彩色发光器件213。即间隔层位于显示层22与多个光学膜层形成单元30之间以将显示层22与多个光学膜层形成单元30间隔开。当然，在间隔层100与彩色发光器件213之间也可以存在其他的层，例如，用于密封彩色发光器件213的密封层等，以防止水氧接触彩色发光器件213。
例如，图2A所示的实施例中，彩色发光器件包括电致发光元件、给电致发光元件提供电信号的阳极和阴极等。例如，该显示基板为发光二极管(LED)显示基板，例如有机发光二极管显示基板(OLED)或无机发光二极管显示基板，可用于发光二极管显示装置。或者，彩色发光器件为其他类型的能够发出彩色光的器件。
例如，在本公开的一些实施例中，参照图2B，图2B所示的显示基板与图2A具有以下区别。该显示基板的每个像素区211的多个子像素开口的每个还包括发出白光的白色子像素开口23，光学膜层形成单元30可设置在白色子像素开口23对应的位置，即多个光学膜层形成单元30的每个在衬底10上的正投影与白色子像素开口23在衬底10上的正投影至少部分重叠，即光学膜层形成单元30在显示层22上的正投影与白色子像素开口23至少部分重 叠。当然，在存在白色子像素开口23的情况下，光学膜层形成单元30也可设置在黑矩阵211对应的位置，即黑矩阵211在衬底10上的正投影覆盖光学膜层形成单元在衬底10上的正投影(这种情况图未示出)。由此，光学膜层形成单元30不会影响进入彩色滤光片(非白色滤光片)的光的透过率，从而不会影响使用该显示基板的显示面板的显示效果。
根据本公开的实施例，衬底的具体种类没有限制要求，本领域技术人员可以根据实际情况灵活选择。在本公开的一些实施例中，当上述显示基板用于LCD、OLED等显示器时，衬底的具体种类包括但不限于金属衬底、聚合物衬底或玻璃衬底；在本公开的另一些实施中，当上述显示基板用于LED屏时，该衬底可为由氮化硅、氧化硅等材料形成的透明保护层。由此，该显示基板应用范围广泛。
例如，在本公开的实施例中，间隔层的材料化学性质稳定、耐腐蚀。例如，间隔层的材料包括氮化硅、氧化硅、氮氧化硅中的至少之一。但本公开的实施例对间隔层的材料不作限定，本领域技术人员可根据实际需求灵活选择本领域中可适用的材料。根据本公开的实施例，形成黑矩阵的材料也没有限制要求，本领域技术人员可根据实际需求灵活选择本领域中可适用的黑矩阵材料。在本公开的实施例中，形成黑矩阵的材料包括但不限于铬黑、炭黑、混合型金属氧化物等材料。
根据本公开的实施例，光学膜层的预定厚度没有限制要求，本领域技术人员可根据画作所用颜料的种类以及不同的画作立体质感等实际需求灵活设计，在此不作限制要求。
例如，在一个实施例中，透明有机材料为聚异丁烯，溶剂为笨，这种情况下，还能够防止显示基板上存在过多水汽，从而可以改善水汽进入显示层，从而有利于保护显示层。例如，在另一个实施例中，透明有机材料为纤维素，溶剂为含水氢氧化铜铵。根据本公开的实施例，透明有机材料和溶剂的具体种类没有限制要求，只要有机材料是透明的。其凝固时间随着其液态时浓度的变化而变化即可，比如随着透明有机材料浓度的增大，其凝固时间越短。所以，可根据透明光学膜层的形成位置与光学膜层形成单元之间的距离来确定所需有机材料的浓度，以此在不同位置形成预定厚度的透明光学膜层，具 体的，当随着透明有机材料浓度的增大，其凝固时间越短时，透明光学膜层的形成位置与光学膜层形成单元之间的距离越远，透明有机材料的浓度越小，其凝固时间较长，使其具有充分的时间从光学膜层形成单元流到透明光学膜层的形成位置；透明光学膜层的形成位置与光学膜层形成单元之间的距离越近，透明有机材料的浓度越大，其凝固时间就较短。
在本公开的一些实施例中，该有机材料为可降解塑料或生物降解材料，比如乳酸等，由此，当采用该显示基板的显示面板更换画作时，可降解塑料或生物降解材料形成的透明光学膜层便会被分解，然后光学膜层形成单元根据新的画作重新形成具有预定折射率的透明光学膜层。
在本公开的另一些实施例中，该有机材料可为聚乙烯醇缩丁醛(PVB)，溶剂只要能将PVB溶解即可，比如为乙醇等。由此，不同浓度的PVB其凝固时间会有所不同，随着浓度的增大，其凝固时间越短。但是由于PVB不易分解，所以采用该显示基板的显示面板更换画作时，可通过设置有机材料回收装置将其回收。
根据本公开的实施例，例如，预定厚度的透明光学膜层具有预定折射率。不同浓度的透明有机材料在其凝固后形成的透明光学膜层的折射率不同，具体的，浓度越大，折射率越大。不同位置形成的不同折射率的透明光学膜层相互配合，可进一步加强透明光学膜层体现的立体质感，而且折射率的不同还可以表达出优化、水墨、蜡笔等不同颜料的画作。
根据本公开的实施例，彩色滤光片的具体种类没有限制要求，本领域技术人员可根据实际需求灵活选择。在本公开的一些实施例中，参照图1A，多个子像素开口可以为设置有红色滤光片的红色子像素开口、设置有绿色滤光片的绿色子像素开口和设置有蓝色滤光片的蓝色子像素开口。在本公开的另一些实施例中，参照图1B，多个子像素开口可以为设置有红色滤光片的红色子像素开口、设置有绿色滤光片的绿色子像素开口、设置有蓝色滤光片的蓝色子像素开口和设置有透明材料的白色子像素开口。在本公开的又一些实施例中，多个子像素开口可以为设置有红色滤光片的红色子像素开口、设置有绿色滤光片的绿色子像素开口、设置有蓝色滤光片的蓝色子像素开口、设置有黄色滤光片的黄色子像素开口和设置有透明材料的白色子像素开口。
根据本公开的实施例，光学膜层形成单元的设置位置没有很大的限制要求，只要保证多个光学膜层形成单元在显示层上的正投影与多个子像素开口不重叠即可。
根据本公开的实施例，光学膜层形成单元的具体结构没有限制要求，只要能实现在所需位置形成具有预定折射率的光学膜层即可。在本公开的实施例中，参照图4-5和图6A-6B，例如，多个光学膜层形成单元30中每个包括：存储微腔31、阀门32和驱动结构33。存储微腔31内设置有透明有机材料和第一溶剂阀门32设置在存储微腔31上，阀门32配置为释放有机材料和第一溶剂以形成透明光学膜层；驱动结构33配置为驱动阀门32打开以释放透明有机材料和第一溶剂以形成所述透明光学膜层以及驱动阀门32关闭以停止释放透明有机材料和第一溶剂。由此，该结构的光学膜层形成单元可以灵活控制透明有机材料和溶剂的释放以及其释放量，具体的，当阀门打开后，驱动结构33可驱动透明有机材料和第一溶剂的释放，使其在所需位置处形成一定厚度的透明有机材料，待其凝固后便得到预定厚度的光学膜层。
根据本公开的实施例，驱动结构的设置位置没有限制要求，可以设置在存储微腔的内部(如图5)，也可以设置在存储微腔的外部(如图4、图6A-6B)，本领域技术人员可以根据实际情况灵活选择，在此不作限制要求。
根据本公开的实施例，对驱动结构的具体结构没有限制要求，只要可以达到驱动阀门32打开以释放透明有机材料和溶剂、提供流动动力以及可以驱动阀门32关闭以停止释放透明有机材料和溶剂即可。例如，在本公开的一些实施例中，参照图4，驱动结构33包括第一微型泵332，例如微型空气泵(比如扇叶)、液压泵等，当透明有机材料和溶剂需要释放时，通过第一微型空气泵将空气压入存储微腔31中，透明有机材料和第一溶剂在空气的挤压下被释放出；例如，在本公开的另一些实施例中，参照图5，驱动结构33包括活塞331，当透明有机材料和溶剂需要释放时，例如通过活塞331朝向阀门32的方向移动，将透明有机材料和第一溶剂推出。由此，结构简单，易控制，而且，当再次填充透明有机材料和第一溶剂时，可将活塞331移动到存储微腔31的远离阀门的一端，以容纳最大量的透明有机材料或溶剂。
例如，在本公开至少一实施例中，控制扇叶的旋转和活塞的移动的方式 没有限制要求，本领域技术人员可根据实际情况灵活选择，比如，驱动结构33还包括电机，扇叶的旋转和活塞的移动可以通过电机来驱动。或者，通过电极驱动第一微型泵332的工作来控制阀门的打开与关闭。例如，阀门32可以为机械阀门，通过驱动结构施加给阀门32的机械力控制阀门32的移动以实现其打开和关闭。又例如，阀门也可以为电磁阀，通过来自驱动结构33的电信号控制电磁阀的打开和关闭以控制有机材料和溶剂的释放。阀门的具体结构本领域技术人员可根据本领域常规技术进行设计。根据本公开的实施例，阀门的设置具体位置没有限制要求，本领域技术人员可根据实际情况在存储微腔上灵活设计阀门的位置。根据本公开的实施例，阀门开启与闭合的控制没有限制要求，本领域技术人员可根据实际需求灵活设置。例如，如图13所示，显示基板还包括控制器34，控制器34与多个光学膜层形成单元30的每个的驱动结构33信号连接，控制器34配置为为驱动结构33提供控制信号以控制驱动结构33驱动阀门32打开和关闭。例如，该信号连接为电连接，控制器34与多个光学膜层形成单元30中的每个中的驱动结构33电连接，驱动结构33在控制器34的控制下完成对阀门32的移动(例如扇叶的旋转和活塞的移动)的驱动。由于多个光学膜层形成单元30中的每个的驱动结构33都分别与控制器34的一个输出端相连，因此，控制器34可通过不同的输出端向对应的驱动结构33输出不同的控制信号，从而实现对各光学膜层形成单元30的工作的独立控制，从而可以根据画作的各个位置的不同需求对各个位置独立进行控制。
例如，控制器34通过硬件或硬件与软件相结合的方式实现，例如控制器34包括驱动电路。例如，控制器34可以是数字处理器(DSP)、可编程逻辑控制器(PLC)等，也可以是通用计算设备例如中央处理单元(CPU)等。例如，将需要显示的画作的各个像素区的需求数据记录于控制器34中，当显示面板工作时，通过控制器34根据各个像素区的需求数据给与各个像素区对应的多个光学膜层形成单元30发送控制信号，以对应各个像素区形成预定厚度、预定折射率的光学膜层。
根据本公开的实施例，根据前面所述，为了可以在不同位置得到预定厚度的光学膜层，或者得到不同折射率的透明光学膜层，就需得到不同浓度的 透明有机材料，参照图6A(图中驱动结构以扇叶为例)，存储微腔31包括溶质腔311和溶剂腔312，溶质腔311中设置有透明有机材料，溶剂腔312中设置有第一溶剂。由此，根据所需形成透明光学膜层与光学膜层形成单元之间的距离来确定所需有机材料的浓度，然后分别释放透明有机材料和溶剂，如此便可得到各种不同浓度的有机材料，待其凝固后便得到预定厚度的光学膜层，以表现出画作中颜料堆叠的层次感、凝固感或者墨迹在纸张上干涸后的凹凸感等不同的画作立体质感，还原画作原始风格。
根据本公开的实施例，为了可以将分别释放出的透明有机材料和第一溶剂混合均匀，参照图6A，例如，存储微腔31还包括混合腔313，混合腔313和溶质腔311和溶剂腔312相通，用于混合溶质腔311释放的透明有机材料和溶剂腔312释放的第一溶剂。由此，可以将溶质腔311释放的透明有机材料和溶剂腔312释放的第一溶剂混合均匀，得到折射率均匀的透明光学膜层，根据本公开的实施例，为了便于分别控制透明有机材料、溶剂以及混合均匀之后的有机材料的释放，可以在溶质腔311、溶剂腔312和混合腔313中分别设有阀门和驱动结构(图中未全部示出)，由此可以实现不同腔室的独立控制，得到不同浓度的有机材料，进而可以在不同位置获得预定厚度的透明光学膜层，进而体现出不同画作的不同的立体质感。
根据本公开的实施例，如前所述，若透明有机材料为PVB，当更换画作时，由于PVB不易分解，可通过设置有机材料回收装置将其回收。例如，显示基板还可以包括第二溶剂释放单元，第二溶剂释放单元释放第二溶剂以溶解所述透明光学膜层，从而可将透明光学膜层溶解后得到的有机材料回收，以再次利用该有机材料。
下面根据本公开的一些实施例，详细介绍透明光学膜层的回收。
在本公开的一些实施例中，参照图7，第二溶剂释放单元50设置在间隔层的一端，例如设置于衬底10的一端，配置为释放第二溶剂以溶解透明光学膜层。由此，溶剂释放单元在控制器的控制下释放溶剂，将透明光学膜层溶解，溶解后的透明光学膜层又变回具有流动性的有机材料，该有机材料可根据更新的画作的需求重新利用，或者被引流到存储微腔，若存储微腔包括溶质腔和溶剂腔，例如将该有机材料引流到溶质腔，由此，可以最大程度的提 高有机材料的利用率。例如，溶剂释放单元中所盛纳的溶剂与存储微腔中的溶剂一致，由此，可以保证透明有机材料的纯度，便于对其浓度和其凝固后形成的透明光学膜层的折射率的控制。
根据本公开的实施例，第二溶剂释放单元的数量没有限制要求，本领域技术人员可以根据实际需求灵活选择。在本公开的一些实施例中，参照图7，第二溶剂释放单元可以为一个容积较大的第二溶剂释放单元，且保证其释放的溶剂可以流到所有像素区对应的第二表面上。在本公开的另一些实施例中，参照图8(图8中仅仅是示例性画出了4个第二溶剂释放单元，并非是对数量的限制)，第二溶剂释放单元可以为多个可以独立控制、容积较小的第二溶剂释放单元，如此，便可以根据透明光学膜层的分布情况，针对性的选择释放溶剂的第二溶剂释放单元，如此便可以节约原料，缩短回收时间，以及减少回收量。
在本公开的另一些实施例中，参照图9，显示基板还可包括有机材料回收单元60，有机材料回收单元60设置在间隔层的与第二溶剂释放单元50相对的一端，(例如，在一个实施例中，有机材料回收单元60设置在衬底10的与第二溶剂释放单元50相对的一端)，且配置为回收透明光学膜层溶解于第二溶剂后产生的有机材料。由此，便于透明光学膜层溶解产生的有机材料的回收。例如，在一个实施例中，在用户使用该彩膜基板时，有机材料回收单元还可以设置于衬底10的下方(衬底10的与设置有光学膜层形成单元的一侧相对的一侧)，由此，溶剂将透明光学膜层溶解后的有机材料可以借助重力流入到有机材料回收单元。
根据本公开的实施例，有机材料回收单元的数量也没有限制要求，本领域技术人员可根据实际需求灵活选择。在本公开的一些实施例中，参照图9，有机材料回收单元为一个容积较大的单元，例如一个容积较大的腔体，且保证可以回收到来自所有像素区中被溶解的有机材料。在本公开的另一些实施例中，参照图10(图10中仅仅是示例性画出了4个有机材料回收单元，并非是对数量的限制)，有机材料回收单元可以包括多个可以独立控制、容积较小的单元，该多个独立控制、容积较小的单元例如为多个腔体，如此，便可以根据透明光学膜层的分布情况，针对性的选择接收被溶解的有机材料。
根据本公开的实施例，为了将有机材料回收单元回收的透明有机材料重新利用，参照图11，有机材料回收单元可进一步包括连接管61，连接管61连通有机材料回收单元60和存储微腔31，配置为将回收至有机材料回收单元60中的所述有机材料输送至存储微腔31。例如，如图6B所示，显示基板还包括回收管36，回收管36连接连接管61和存储微腔31，将回收的所述有机材料通过连接管36输送至存储微腔31。由此，可实现有机材料的回收利用。
根据本公开的实施例，被溶解后的有机材料被引流到存储微腔的方法没有限制要求，本领域技术人员可根据实际需求灵活选择。例如，参考图6B，在本公开的一些实施例中，多个光学膜层形成单元的每个还包括回收腔35、连通管37和第二微型泵。回收腔35与连接管61连接以接收来自有机材料回收单元60的所述有机材料。例如，回收腔35通过回收管36与连接管61连接以接收来自有机材料回收单元60的所述有机材料；或者，回收腔35直接与连接管61连接以接收来自有机材料回收单元60的所述有机材料。连通管3连通回收腔35与存储微腔31。第二微型泵配置为将回收腔35中接收的有机材料通过连通管37运输至存储微腔31。例如，在图6B所示的实施例中，连通管37连通回收腔35与溶质腔311，第二微型泵配置为将回收腔35中接收的有机材料通过连通管37运输至溶质腔311中(例如，在另一实施例中，连通管37连通回收腔35与溶剂腔312，第二微型泵配置为将回收腔35中接收的有机材料通过连通管37运输至溶剂腔312中)。例如，第二微型泵设置于回收腔35中或设置于回收管36中。例如，第二微型泵为空气泵或液压泵。由此，在第二微型泵的作用下，被溶解的有机材料经过回收管36被回收至回收腔35中，再次重新利用。
在本公开的另一些实施例中，也可以将被溶解的有机材料直接进入回收管36中，再依次经由回收腔35、连通管37回收至溶质腔中，再次被重新利用。本公开实施例对有机材料回收单元、回收腔、回收管等的具体结构和设置方式不作限定，只要能够达到上述效果即可，本领域技术人员可根据需要设计。根据本公开的实施例，为了可以将溶解得到的有机材料更彻底的被回收，参照图12，该显示基板还可包括清扫单元70，清扫单元70设置在间隔 层的至少一端，配置为清扫形成有所述透明光学膜层的表面。例如，在图1A和图1B所示的实施例中，清扫单元70设置在衬底10的至少一端，配置为清扫衬底10的第二表面。由此，在对透明光学膜层进行溶解回收时，清扫单元可以在控制器的控制下对衬底10的第二表面进行清扫，增加溶解后的有机材料的流动性，使的透明光学膜层更好的溶于溶剂中，进而确保有机材料回收的更加彻底，减少有机材料的浪费，提高使用该显示基板的显示面板的画面显示质量。根据本公开的实施例，清扫单元的具体种类没有限制要求，本领域技术人员可根据实际需求灵活选择，在本公开的实施例中，清扫单元可以为顺序排列的刷子，设置在衬底的至少一端，又例如，在一个实施例中，清扫单元可以设置在衬底的相对的两端。由此，对有机材料的清扫更干净彻底，清扫效率更高。
本公开至少一实施例还提供一种显示面板。根据本公开的实施例，该显示面板包括前面所述的显示基板。由此，该显示面板显示的画作可直接体现出油画、水墨或蜡笔等不同颜料的画作，也可表达出画作中颜料堆叠的层次感、凝固感或者墨迹在纸张上干涸后的凹凸感等不同的画作立体质感，还原画作原始风格。
本领域技术人员可以理解，该显示面板除了前面所述的显示基板外，该显示面板还具备常规显示面板所必备的结构或部件。例如，该显示面板可以为液晶显示面板。例如，该液晶显示面板包括图1A或图1B所示的彩膜基板。除了前面所述的显示基板外，该液晶显示面板还包括背光源、阵列基板以及液晶层等常规的必备结构。例如，在该LCD显示面板中，滤光片位于衬底的靠近液晶层的一侧，多个光学膜层形成单元位于衬底的远离液晶层的一侧。
例如，该显示面板可以为电致发光显示面板。例如，该电致发光显示面板包括图2A或图2B所示的显示基板。例如，该电致发光显示面板还包括位于间隔层100与彩色发光器件213之间的密封层，以用于密封彩色发光器件213，以及封装层等。
对于本公开实施例提供显示面板的其他结构，本领域技术人员可参考常规技术。
根据本公开的实施例，该显示面板可用于各种显示装置中，本领域技术 人员可以根据实际情况灵活选择。在本公开的实施例中，该显示面板可用于显示画作的电子画框，由此该电子画框显示画作时，可直接体现出油画、水墨或蜡笔等不同颜料的画作，也可表达出画作中颜料堆叠的层次感、凝固感或者墨迹在纸张上干涸后的凹凸感等不同的画作立体质感，还原画作原始风格，提高用户体验。
本公开实施例还提供一种前面所述显示面板的显示方法。该方法包括：在显示基板所显示的图像的视觉粗糙度超过预定阈值的区域形成透明光学膜层。例如，该透明光学膜层具有预定厚度。例如，在不同的像素区形成的透明光学膜层的厚度不同。由此，在显示基板所显示的图像的视觉粗糙度超过预定阈值的区域形成具有预定厚度的透明光学膜层。例如，该图像为画作。
例如，根据上述区域与上述区域所属于的像素区中的光学膜层形成单元之间的距离来确定所需透明有机材料的浓度，例如，距离越远，浓度越小，凝固时间越长。光学膜层形成单元在控制器的控制下释放所需浓度的透明有机材料，之后流动到上述区域，并在上述区域凝固为具有预定厚度的透明光学膜层，该透明光学膜层便可以很好地体现出油画、水墨或蜡笔等不同颜料的画作，也可较佳的表达出画作中颜料堆叠的层次感、凝固感或者墨迹在纸张上干涸后的凹凸感等不同的画作立体质感，还原画作原始风格。而且，上述显示方法控制简单，易操作。
例如，将需要显示的画作的各个像素区的需求数据记录于控制器34中，这些数据例如包括各个像素区的视觉粗糙度，例如可以用透明光学膜层的厚度来表征。例如，先获取纸质画作表面不同区域的粗糙度，根据该粗糙度计算各个像素区的视觉粗糙度，从而得到个多个像素区的每个所需的透明光学膜层的厚度。当显示面板工作时，通过控制器34根据各个像素区的需求数据给与各个像素区对应的多个光学膜层形成单元30发送控制信号，以对应各个像素区形成具有预定厚度的透明光学膜层。从而，在本公开实施例提供的显示面板中，通过具有预设厚度的透明的光学膜层模拟纸质画作的颜料的质感和画作表面的起伏，以形成画作的视觉粗糙度，从而表达出纸质画作的颜料质感和由于颜料堆积而形成的表面的起伏的视觉感受。根据本公开的实施例，透明光学膜层的厚度没有限制要求，本领域技术人员根据所需表达的画作中 颜料堆叠的层次感、凝固感或者墨迹在纸张上干涸后的凹凸感等画作的不同质感情况而设定即可。例如，画作的所述区域的表面粗糙度越大，透明光学膜层的厚度越大。如果所需的透明光学膜层的厚度较厚，一次形成的透明光学膜层的厚度不能达到所需要的厚度时，可在上次形成的透明光学膜层的基础上再次形成一次透明光学膜层的厚度，进而增加透明光学膜层的厚度，使其达到最终所需要的透明光学膜层的厚度。
根据本公开的实施例，预定阈值的具体值也没有限制要求，本领域技术人员可根据画作表面粗糙度等实际需求灵活选择。在本公开的实施例中，预定阈值可以为0.1毫米、0.05毫米、0.02毫米等等。
在本公开的又一方面，本公开提供了一种显示装置。根据本公开的实施例，该显示装置包括前面所述的显示面板。由此，该显示装置显示的画作可直接体现出油画、水墨或蜡笔等不同颜料的画作，也可表达出画作中颜料堆叠的层次感、凝固感或者墨迹在纸张上干涸后的凹凸感等不同的画作立体质感，还原画作原始风格。
根据本公开的实施例，该显示装置的具体种类没有特别限制，可以为本领域任何具有显示功能的装置、设备，例如包括但不限于手机、平板电脑、计算机显示器、游戏机、电视机、显示屏幕、用于显示画作的电子画框、可穿戴设备及其他具有显示功能的生活电器或家用电器等。
当然，本领域技术人员可以理解，除了前面所述的显示面板，本公开所述的显示装置还可以包括常规显示装置所具有的必要的结构和部件，以手机为例进行说明，除了具有本公开的显示面板外，其还可以具有触控屏、外壳、CPU、照相模组、指纹识别模组、声音处理系统等等常规手机所具有的结构和部件，在此不再过多赘述。为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。以下所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其它实施例，都属于本公开保护的范围。
