背景技术
随着显示技术的发展，曲面显示越来越受到面板厂商和消费者的推崇，曲面显示面板是一种采用柔性塑料的显示面板，主要通过OLED(Organic Light Emitting Diode，有机发光二极管)面板来实现，相比于传统的直面显示面板，曲面显示面板的弹性更好，不易破碎，且能带来更直观的视觉感受。
目前，在制作曲面显示面板的工艺中，使用正常的mask(掩模板)工艺制作阵列基板和彩膜基板，将制作好的阵列基板和彩膜基板对合之后，由于采用弯曲技术，要将原有的直面显示面板弯曲，曲面显示面板会以显示面板的中心位置为基准，使得彩膜基板上的黑矩阵与阵列基板上的非像素开口区域，从原本正对应的位置发生一定程度的偏移。

具体实施方式
为使本公开的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本公开作进一步详细的说明。下面所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。
另外，在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或更多个实施例在没有这些具体细节的情况下也可以被实施。在其他情况下，公知的结构和装置以图示的方式体现以简化附图。
在发明人应用在先技术时，发现在相关技术中，对于曲面显示面板，彩膜基板上的黑矩阵会遮蔽阵列基板上的部分像素开口区域，且越到曲面显示面板的边缘，契合度越不好，黑矩阵与非像素开口区域的偏移量越大，导致开口率降低，且容易发生漏光现象。
图2示出了本公开的一个实施例的一种曲面显示面板的制作方法的流程图。该方法可以包括如下步骤：
步骤201：根据预定的补正量调整阵列基板和彩膜基板中至少一者的曲边尺寸以使得所述阵列基板的曲边尺寸与所述彩膜基板的曲边尺寸的差值与预定的补正量相符；
步骤202：根据调整后的曲边尺寸来制作阵列基板和彩膜基板；以及
步骤203：将所述阵列基板与所述彩膜基板进行对合。
在本公开的实施例中，首先确定阵列基板和彩膜基板的曲边尺寸，具体地，根据预定的补正量调整阵列基板和彩膜基板中至少一者的曲边尺寸，以使得所述阵列基板的曲边尺寸与所述彩膜基板的曲边尺寸的差值与预定的补正量相符。可以根据预定的补正量只调整阵列基板的曲边尺寸，彩膜基板的曲边尺寸无需做调整；或者，可以根据预定的补正量只调整彩膜基板的曲边尺寸，阵列基板的曲边尺寸无需做调整；或者，还可以根据预定的补正量调整阵列基板和彩膜基板的曲边尺寸。根据经过调整的阵列基板和彩膜基板的曲边尺寸(可以同时调整阵列基板和彩膜基板的曲边尺寸，也可以仅调整其中之一的曲边尺寸)，可以分别制作阵列基板和彩膜基板。最后，将制作得到的阵列基板和彩膜基板进行对合。
当彩膜基板62的黑矩阵621与阵列基板61上的非像素开口区域611没有偏移时，黑矩阵(或非像素开口区域)的宽度为第二宽度D2，如图6所示。如果没有基于补正量调整上述曲边尺寸，如图1所示，则在阵列基板11和彩膜基板12弯曲后，彩膜基板12上的黑矩阵121与阵列基板11上的非像素开口区域111，从原本正对应的位置发生一定程度的偏移，偏移之后黑矩阵(或非像素开口区域)的宽度与产生偏移的宽度的总和为第一宽度D1。D1-D2为彩膜基板上的黑矩阵与阵列基板上的非像素开口区域之间的偏移量。本公开通过预先根据基本对盒后无偏移的相关结构尺寸计算补正量然后根据补正量调整阵列基板的曲边尺寸和/或彩膜基板的曲边尺寸，对偏移量D1-D2进行补正，使得彩膜基板的黑矩阵与阵列基板上的非像素开口区域没有偏移。换言之， 所述补正量用于补偿由于曲面显示面板的曲率导致的彩膜基板上的黑矩阵与阵列基板上的非像素开口区域的错位。
下面具体介绍补正量的计算方法。
参照图3，示出了本公开的实施例中的一种补正量的计算原理图。
如图3所示，曲面显示面板向彩膜基板的方向弯曲(即阵列基板位于曲面显示面板的凸出的一侧，彩膜基板位于曲面显示面板的凹陷的一侧)，31为阵列基板，32为彩膜基板，弯曲后的曲面显示面板有固定的曲率，圆心为O，曲率半径为R，OB1和OB2的夹角为θ，从B1沿着阵列基板31至B2的距离为阵列基板31的曲边长度，其曲边尺寸为L2，阵列基板31的厚度为T2，彩膜基板32的厚度为T1，阵列基板31与彩膜基板32之间的间距为n，假设从A1沿着彩膜基板32至A2的距离为根据补正量调整后的彩膜基板曲边的长度，其曲边尺寸为L1，则有如下计算公式：
(R+T1+n)×θ×π/180＝L2，   (1)
以及(R+T1)×θ×π/180＝L1；   (2)
根据上述计算公式(1)和计算公式(2)可以得到公式(3)：
L1＝L2×(R+T1)/(R+T1+n)，   (3)
所以补正量Min＝(L2-L1)/L2＝[L2-L2×(R+T1)/(R+T1+n)]/L2＝[1-(R+T1)/(R+T1+n)]；   (4)
公式(4)给出了补正量Min的计算方法，补正量实际表示的是补正系数，即单位长度下需要补正的值，在对阵列基板或彩膜基板的曲边尺寸进行调整时，需要通过补正量Min乘以补正位置的实际长度，确定补正的长度。本公开中由于无法获取偏移量D1-D2，不能直接根据偏移量确定补正量，而需要根据上述公式(4)来获得补正量，通过补正量去消除偏移量。作为示例，补正量可以是所述补正量是所述阵列基板的曲边尺寸与所述彩膜基板的曲边尺寸的差值与所述阵列基板的曲边尺寸的比例，或者，也可以是所述彩膜基板的曲边尺寸与所述阵列基板的曲边尺寸的差值与所述彩膜基板的曲边尺寸的比例。
作为示例，补正量等于1减去第一尺寸与第二尺寸的比值后得到的差值；所述第一尺寸为所述曲面显示面板的曲率半径与所述彩膜基板的厚度的和，所述第二尺寸为所述第一尺寸以及所述阵列基板与所述彩膜基板之间的间距的和，例如当曲面显示面板向彩膜基板的方向弯曲(即阵列基板位于曲面显示面板的凸出的一侧且彩膜基板位于曲面显示面板的凹陷的一侧)时。
其中，可以根据上述补正量调整彩膜基板的曲边尺寸，彩膜基板的曲边尺寸为原始曲边尺寸减去补正量后的尺寸，补正后的曲边尺寸小于原始曲边尺寸；或者还可以根据补正量调整阵列基板的曲边尺寸，阵列基板的曲边尺寸为原始曲边尺寸加入补正量后的尺寸，补正后的曲边尺寸大于原始曲边尺寸。作为示例，也可以通过相对于所 述彩膜基板的曲边尺寸增加所述阵列基板的曲边尺寸或者通过相对于所述阵列基板的曲边尺寸减小所述彩膜基板的曲边尺寸，以使得所述阵列基板的曲边尺寸与所述彩膜基板的曲边尺寸的差值与预定的补正量相符。
另外，还可以根据补正量同时调整阵列基板和彩膜基板的曲边尺寸，则根据第一补正量调整彩膜基板的曲边尺寸，彩膜基板的曲边尺寸为原始曲边尺寸减去第一补正量后的尺寸，根据第二补正量调整阵列基板的曲边尺寸，阵列基板的曲边尺寸为原始曲边尺寸加入第二补正量后的尺寸，第一补正量与第二补正量的和等于上述的补正量；其中，第一补正量和第二补正量均为正数，作为示例，可将第一补正量和第二补正量的差值设置成接近于零。作为示例，在上述示例中，彩膜基板的原始曲边尺寸和阵列基板的原始曲边尺寸可以基本上相等。
在本公开的另一种实施例中，当曲面显示面板向阵列基板的方向弯曲(彩膜基板位于所述曲面显示面板的凸出的一侧且所述阵列基板位于所述曲面显示面板的凹陷的一侧)时，补正量的计算方法与上述的计算方法类似，在此不做详述。例如，补正量可以等于1减去第一尺寸与第二尺寸的比值后得到的差值；所述第一尺寸为所述曲面显示面板的曲率半径与所述阵列基板的厚度的和，所述第二尺寸为所述第一尺寸以及所述阵列基板与所述彩膜基板之间的间距的和。
其中，可以根据上述补正量调整阵列基板和/或彩膜基板的曲边尺寸，所述阵列基板的曲边尺寸为原始曲边尺寸减去所述补正量后的尺寸；或者，所述彩膜基板的曲边尺寸为原始曲边尺寸加入所述补正量后的尺寸。作为示例，也可以通过相对于所述阵列基板的曲边尺寸增加所述彩膜基板的曲边尺寸或者通过相对于所述彩膜基板的曲边尺寸减小所述阵列基板的曲边尺寸，以使得所述彩膜基板的曲边尺寸与所述阵列基板的曲边尺寸的差值与预定的补正量相符。
在本公开的实施例中，阵列基板的曲边尺寸可以是阵列基板在曲面显示面板的弯曲横截面(例如图3和图6中所示的曲面显示面板的横截面)中的长度，而彩膜基板的曲边尺寸可以是彩膜基板在曲面显示面板的弯曲横截面中的长度。
作为示例，在将阵列基板与彩膜基板进行对合时，阵列基板和彩膜基板的中心对准。
具体的，可以根据所述补正量与所述曲面显示面板的中心位置对应的坐标值，制作掩模板，利用所述掩模板制作所述阵列基板或所述彩膜基板。
本公开的实施例中，根据预定的补正量与曲面显示面板的中心位置对应的掩模板的坐标值，制作相应的掩模板；其中，可以制作与已经基于补正量调整曲边尺寸的彩膜基板对应的掩模板，和与没有基于补正量调整曲边尺寸的阵列基板对应的掩模板；还可以制作与已经基于补正量调整曲边尺寸的阵列基板对应的掩模板，和与没有基于补正量调整曲边尺寸的彩膜基板对应的掩模板。然后，利用包含所述补正量的掩模板 制作相应的阵列基板或彩膜基板。
例如，55寸曲面显示面板的大小为1219.6×689.8mm，其向彩膜基板的方向弯曲(即阵列基板位于曲面显示面板的凸出的一侧且彩膜基板位于曲面显示面板的凹陷的一侧)，彩膜基板的厚度T1为0.5mm，曲率半径R为3000mm，阵列基板与彩膜基板之间的间距n为3.5μm，即为0.0035mm，根据上述计算公式得到补正量Min＝[1-(3000+0.5)/(3000+0.5+0.0035)]＝1.2×10 -6＝0.12μm/100mm，由于曲面显示面板的尺寸参数一般为mm，为了方便制作包含补正量Min的掩模板，需要将补正量的单位折算成μm/100mm，补正量Min＝0.12μm/100mm实际表示的是补正系数，当掩模板对应的图案尺寸为100mm时，则需要补正的长度为0.12μm。该55寸曲面显示面板的彩膜基板对应的掩模板的补正量为0.12μm/100mm，根据该补正量和55寸曲面显示面板的中心位置对应的掩模板的坐标值，制作与已经基于补正量调整曲边尺寸的彩膜基板对应的掩模板。
参照图4，示出了本公开的一种掩模板的结构示意图。
如图4所示，41为阵列基板或彩膜基板的掩模板，以41为彩膜基板的掩模板进行说明，掩模板41中只包含一个掩模区域，其中，掩模区域411为不包含补正量的掩模区域，对应形成一个没有基于补正量对曲边尺寸进行调整的彩膜基板，掩模区域412为包含补正量的掩模区域，对应形成一个基于补正量对曲边尺寸进行调整的彩膜基板，包含补正量的掩模区域412相对于不包含补正量的掩模区域411，其长边以掩模区域412的中心位置为基准向内缩小。
图5示出了本公开的另一种掩模板的结构示意图。
如图5所示，42为阵列基板或彩膜基板的掩模板，以42为彩膜基板的掩模板进行说明，掩模板42中包含四个掩模区域，每个掩模区域对应形成一个彩膜基板，其中，掩模区域421为不包含补正量的掩模区域，对应形成一个没有基于补正量对曲边尺寸进行调整的彩膜基板，掩模区域422为包含补正量的掩模区域，对应形成一个基于补正量对曲边尺寸进行调整的彩膜基板，包含补正量的掩模区域422相对于不包含补正量的掩模区域421，其长边以掩模区域422的中心位置为基准向内缩小，而不是以掩模板42的中心位置为基准向内缩小，对于其余三个掩模区域，也是以各自的中心位置为基准向内缩小。
因此，曲面显示面板缩小或增大的边为曲面显示面板的长边，短边无需缩小或增大。
本公开实施例中，可以利用包含补正量的掩模板制作至少一个阵列基板或至少一个彩膜基板，所述阵列基板和彩膜基板中一者的曲边尺寸为以其中心位置为基准相对于所述阵列基板和彩膜基板中另一者的曲边尺寸进行缩小或增大后的尺寸，例如，所述阵列基板的曲边尺寸为以其中心位置为基准进行缩小或增大后的尺寸，或所述彩膜 基板的曲边尺寸为以其中心位置为基准进行增大或缩小后的尺寸，其中，所述掩模板包括至少一个掩模区域，一个掩模区域对应形成一个阵列基板或一个彩膜基板。
其中，形成后的一个阵列基板的曲边尺寸是根据该阵列基板的中心位置为基准进行缩小或增大后的尺寸；形成后的一个彩膜基板的曲边尺寸是根据该彩膜基板的中心位置为基准进行增大或缩小后的尺寸。
具体的，还可以根据所述补正量与所述曲面显示面板的中心位置对应的坐标值，调整曝光机的曝光位置参数，基于所述曝光位置参数，制作所述阵列基板或所述彩膜基板。
本公开的实施例中，制作阵列基板和彩膜基板通常使用渐进式曝光机，曝光机是通过掩模板将光折射到基板上，当掩模板与基板的距离不同时，基板上曝光的位置也会相应变化。根据预定的补正量与曲面显示面板的中心位置对应的掩模板的坐标值，在渐进式曝光机的菜单上，调整掩模板与基板之间的距离，此时，基板可以为阵列基板或彩膜基板，通过掩模板与基板之间的距离调整曝光机的曝光位置参数，此时，掩模板为不包含补正量的掩模板，基于曝光机的曝光位置参数，调整需要曝光的部分，制作相应的阵列基板或彩膜基板。
本公开实施例中，将制作好的阵列基板和彩膜基板进行对合，形成曲面显示面板，此时，由于阵列基板和/或彩膜基板中包含预定的补正量，使得彩膜基板的黑矩阵与阵列基板的像素开口区域没有偏移，实现了弯曲后的阵列基板与彩膜基板无偏移对合。
图6示出了本公开的实施例中基于补正量调整曲边尺寸之后的曲面显示面板的结构示意图。
如图6所示，曲面显示面板向彩膜基板的方向弯曲，61为阵列基板，62为彩膜基板，其中，阵列基板61的曲边尺寸和/或彩膜基板62的曲边尺寸为根据预定的补正量调整后的尺寸，彩膜基板62上的黑矩阵621与阵列基板61上的非像素开口区域611完全对合，黑矩阵621(或非像素开口区域611)的宽度为第二宽度D2。作为示例，所述阵列基板61的曲边尺寸与所述彩膜基板62的曲边尺寸的差值与预定的补正量相符。
本公开实施例中，通过制作阵列基板和彩膜基板，所述阵列基板的曲边尺寸和/或所述彩膜基板的曲边尺寸为根据预定的补正量调整后的尺寸，将所述阵列基板与所述彩膜基板进行对合。通过预先计算补正量，在制作阵列基板和彩膜基板的阶段，根据预定的补正量调整阵列基板的曲边尺寸和/或所述彩膜基板的曲边尺寸，以实现弯曲后的阵列基板与彩膜基板无偏移对合，提高开口率，减少漏光现象的发生。
本公开实施例还公开了一种曲面显示面板，包括对盒设置的阵列基板和彩膜基板，所述阵列基板的曲边尺寸和/或所述彩膜基板的曲边尺寸为根据预定的补正量调整后的尺寸。所述阵列基板的曲边尺寸与所述彩膜基板的曲边尺寸的差值与预定的补正量 相符。
其中，所述阵列基板的非像素开口区域与所述彩膜基板上的黑矩阵之间对准(例如完全没有偏移)。
如图6所示，曲面显示面板向彩膜基板的方向弯曲，61为阵列基板，62为彩膜基板，其中，阵列基板61的曲边尺寸和/或彩膜基板62的曲边尺寸为根据预定的补正量调整后的尺寸，彩膜基板62上的黑矩阵621与阵列基板61上的非像素开口区域611完全对合。
根据前述实施例中的计算方法获得补正量，作为示例，当曲面显示面板向彩膜基板的方向弯曲时，补正量等于1减去第一尺寸与第二尺寸的比值后得到的差值，所述第一尺寸为所述曲面显示面板的曲率半径与所述彩膜基板的厚度的和，所述第二尺寸为所述第一尺寸以及所述阵列基板与所述彩膜基板之间的间距的和；可以根据上述补正量调整彩膜基板的曲边尺寸，彩膜基板的曲边尺寸为原始曲边尺寸减去补正量后的尺寸，补正后的曲边尺寸小于原始曲边尺寸；或者还可以根据补正量调整阵列基板的曲边尺寸，阵列基板的曲边尺寸为原始曲边尺寸加入补正量后的尺寸，补正后的曲边尺寸大于原始曲边尺寸。
作为示例，当曲面显示面板向阵列基板的方向弯曲时，补正量的计算方法与上述的计算方法类似，在此不做详述。则补正量等于1减去第一尺寸与第二尺寸的比值后得到的差值；所述第一尺寸为所述曲面显示面板的曲率半径与所述阵列基板的厚度的和，所述第二尺寸为所述第一尺寸以及所述阵列基板与所述彩膜基板之间的间距的和；可以根据上述补正量调整阵列基板和/或彩膜基板的曲边尺寸，所述阵列基板的曲边尺寸为原始曲边尺寸减去所述补正量后的尺寸；或者，所述彩膜基板的曲边尺寸为原始曲边尺寸加入所述补正量后的尺寸。
