目前，市面上常见的一类显示装置为液晶显示装置。常规液晶显示装置的结构一般包括液晶显示面板和位于液晶显示面板入光侧的背光模组。其中，液晶显示面板包括：相对设置以形成液晶盒的阵列基板和滤光基板，位于阵列基板和滤光基板之间的液晶，位于阵列基板的远离滤光基板一侧的第一偏光片，以及位于滤光基板的远离阵列基板一侧的第二偏光片，其中，阵列基板相对滤光基板更加靠近背光模组，第一偏光片和第二偏光片的偏光方向正交。液晶显示面板包括多个像素单元，每个像素单元包括颜色各不相同的多个子像素。同一像素单元的子像素按照一定比例混光，可以使像素单元显示出人眼可见的彩色。此类常规液晶显示装置由于自身结构特点，存在画面对比度欠佳和暗态漏光的技术缺陷。
为改善上述缺陷，相关技术提出一种采用双屏驱动技术的液晶显示装置。与上述常规液晶显示装置的主要不同在于，如图1所示，其显示面板100’包括调光液晶面板2’和显示液晶面板1’，调光液晶面板2’和显示液晶面板1’通过一面状的胶层3’粘接在一起。其中，显示液晶面板1’与上述液晶显示面板的结构和工作原理类似，调光液晶面板2’位于显示液晶面板1’的入光侧且位于背光模组的出光侧(背光模组在图中未示出，背光模组的出光见图中的虚线箭头所示)，包括呈阵列排布的多个调光像素20’。每个调光像素20’作为一个调光单元，与显示液晶面板1’的若干个子像素10’位置相对，用于控制经由该调光像素20’射入显示液晶面板1’相应区域的背光的方向和强弱。
相关技术的液晶显示装置可以实现对画面较为精细的区域调光，其原理为，根据所显示画面在不同区域的灰阶，调整调光液晶面板2’的相应调光像素20’的透光性(即允许背光透过的方向和/或强弱)。例如，对于画面亮度较高的区域，调光液晶面板2’的相应调光像素20’的透光率也调整地相对较高；而对于画面亮度较低的区域，调光液晶面板2’的相应调光像素20’的透光率也调整的相对较低；对于画面显示为 黑色的区域，调光液晶面板2’的相应调光像素20’的透光率调整至基本为零。该类液晶显示装置与上述的常规液晶显示装置相比，可以克服画面暗态漏光的缺陷，对比度显著提升，从而为用户带来较佳的观看体验。尤其是，当液晶显示装置进行HDR(High-Dynamic Range，高动态范围图像)显示时，区域调光使画面的亮度范围更广，低灰阶过渡更加自然，显示效果更佳。
然而，上述可以实现区域调光的显示面板，由于胶层的厚度均一性和表面平整度难以保证，导致显示画面经常存在条纹、彩虹纹和色偏等缺陷。而且，胶层由于具有一定厚度，透过率不能达到100％，因此，对显示面板的透过率影响也比较大。为达到画面亮度要求，就需要增加背光的功耗，导致显示装置能耗较高。另外，胶层的设置还增加了显示面板的厚度和重量，不符合显示装置的超轻以及超薄设计理念。
为解决上述技术问题，本公开实施例提供了一种显示面板、显示装置及显示面板的制作方法。
如图2和图3所示，本公开一实施例提供的显示面板100，包括：
显示液晶面板1，包括呈阵列排布的多个子像素10；
调光液晶面板2，位于显示液晶面板1的入光侧，包括呈阵列排布的多个调光像素20；
框胶31，位于调光液晶面板2和显示液晶面板1之间，框胶31的靠近调光液晶面板2的一侧与调光液晶面板2粘接，框胶31的靠近显示液晶面板1的一侧与显示液晶面板1粘接。
其中，显示液晶面板1用于实现画面显示，调光液晶面板2用于根据显示液晶面板1所显示画面在不同区域的灰阶，调整相应调光像素20的透光性。关于显示液晶面板1和调光液晶面板2的结构和工作原理参见前述相关技术的描述，这类不再重复赘述。
相关技术的显示面板，由于连接显示液晶面板1和调光液晶面板2的胶层的厚度均一性和表面平整度较难保证，导致显示画面经常存在条纹、彩虹纹和色偏等缺陷。此外，胶层对显示面板的透过率影响也比较大，从而增加了显示装置的功耗。另外，胶层的设置还增加了显示面板的厚度和重量。
在本公开上述实施例技术方案中，采用了非面状的框胶31设计，从而避免了因面状胶层厚度均一性和表面平整度难以保证而带来的上述技术问题，改善了显示画面 的条纹、彩虹纹和色偏等现象。框胶31设置在靠近显示面板边缘的位置，可以避开显示面板的有效显示区域，因此对显示面板的透过率基本没有影响，这有利于降低显示装置的功耗。此外，采用了非面状的框胶31设计，还能减小显示面板的厚度和重量。
如图2和图3所示，在本公开的一个实施例中，显示面板还包括：多个支撑单元32，该多个支撑单元32位于显示液晶面板1和调光液晶面板2之间，且位于框胶31的内侧，即位于框胶31更加靠近有效显示区域的一侧。该多个支撑单元32支撑于显示液晶面板1和调光液晶面板2之间，可以有效避免显示液晶面板1和调光液晶面板2对向弯曲，以及避免因显示液晶面板1和调光液晶面板2相贴合而产生的水波纹，从而保证框胶31、调光液晶面板2和显示液晶面板1所构成盒形腔体001的盒厚均一性，这有利于提升显示的品质。在一个实施例中，多个支撑单元32呈阵列状均匀排布。多个支撑单元32和框胶31将显示液晶面板1和调光液晶面板2间隔开，并保证其间距在各处的均一性。
其中，支撑单元32的形状不限，可以为柱体状、锥体状或立方体状等等。如图3所示，在本公开的一些实施例中，支撑单元32的形状为圆柱体状。在本公开的另一些实施例中，支撑单元32的形状也可以为圆锥台状。关于支撑单元32的更多形状选择，在此不再一一列举。
在本公开的一些实施例中，支撑单元32的等效柱径(即将支撑单元32等效为圆柱体后的底面直径)可以设计为0.1mm～0.3mm，略宽于显示液晶面板1上栅线的设计宽度，以保证支撑单元32的机械强度。支撑单元32的分布密度可以设计为1.8mm 2/cm 2～7.1mm 2/cm 2。支撑单元32的高度可以设计为0.02mm～0.4mm。支撑单元32的具体参数尺寸、排列间距等需要结合产品结构尺寸、产品重量、大气压力、设计最大支撑力以及光学影响等因素来确定。
显示面板制作时，支撑单元32可以预先形成在调光液晶面板2的靠近显示液晶面板1的一侧，或者，预先形成在显示液晶面板1的靠近调光液晶面板2的一侧。支撑单元32可以采用有机材料或无机材料，可以通过图案化工艺形成。此外，支撑单元32也可以采用胶类材料，预先涂布在显示液晶面板1或调光液晶面板2上。例如，在一些实施例中，支撑单元32采用胶类材料，其在靠近调光液晶面板2的一侧与调光液晶面板2粘接，其在靠近显示液晶面板1的一侧与显示液晶面板1粘接。
在本公开的一些实施例中，支撑单元32与框胶31的材料相同，这样框胶31和 支撑单元32的材料压缩率相同，可以进一步提高调光液晶面板2和显示液晶面板1所构成盒形腔体001的盒厚均一性。支撑单元32与框胶31的材料类型不限，例如可以为透明光学胶(Optically Clear Adhesive，OCA)、光学透明树脂(Optical Clear Resin，OCR)或聚丙烯酸酯类胶(VHB胶)，等等。
如图2所示，显示液晶面板1上通常设置有用于遮挡栅线、数据线以及薄膜晶体管等结构(图中未示出)的第一遮光矩阵13。在本公开的一些实施例中，在垂直于显示液晶面板1的方向上，支撑单元32处于第一遮光矩阵13的遮光区域内，即：从显示液晶面板1的出光侧观察，支撑单元32被第一遮光矩阵13遮挡而不可见。采用该设计，支撑单元32的设置位置避开了子像素10的开口区，所以对显示面板的光学均一性基本没有影响。
如图2所示，调光液晶面板2上通常设置有用于遮挡其栅线(图中未示出)的第二遮光矩阵14。由于显示液晶面板1和调光液晶面板2的分辨率不同，因此，第一遮光矩阵13和第二遮光矩阵14的图案通常也不相同。在本公开的一些实施例中，在垂直于调光液晶面板2的方向上，支撑单元32还可以处于第二遮光矩阵14的遮光区域内，其设置位置避开了调光像素20的开口区，因此，基本不会影响到调光液晶面板的开口率。
在本公开实施例中，框胶31可以呈闭合框或者不闭合框形状。如图3所示，在本公开的一些实施例中，框胶31呈闭合框形状，具体呈口字形，并且，框胶31、调光液晶面板2和显示液晶面板1构成的盒形腔体001为真空腔体。即调光液晶面板2和显示液晶面板1之间不存在空气层，这样可以减弱因光线在空气层中传播而可能导致的彩虹纹，以及子像素边缘的光晕，从而进一步提升显示的品质。另外，调光液晶面板2和显示液晶面板1在真空环境中粘接，还可以提高粘接的粘度。在本公开的一些其它实施例中，框胶也可以呈不闭合框形状，例如包括相间隔并且大致呈口字形排列的多段胶条。
请参考图2所示，在本公开的一些实施例中，框胶31的宽度满足：c＝(0.5*b*Q)/P，其中：c为框胶的宽度，单位为mm；b为调光液晶面板的短边长度，单位为mm；Q为常规使用环境下的平均风载荷，单位为kPa；P为框胶材料的粘接强度，单位为kPa。根据该设计规则，框胶31的宽度c可以设计为2mm～5mm。
在本公开的一些实施例中，框胶31外边缘与调光液晶面板2边缘的距离满足：s＝(t-c)/2，其中：s为框胶外边缘与调光液晶面板边缘的距离；t为与框胶位置相对的 第二遮光矩阵的宽度，单位为mm；c为框胶的宽度，单位为mm。根据该设计规则，框胶31的外侧边缘至调光液晶面板2的边缘的距离s可以设计为0.5mm～2mm。
在本公开的一个实施例中，如图3所示，显示液晶面板1包括第一偏光片11，第一偏光片11位于显示液晶面板1的靠近调光液晶面板2的一侧；框胶31的远离调光液晶面板2的一侧与第一偏光片11粘接。在本公开的另一个实施例中，如图4所示，框胶31是位于第一偏光片11的边缘外侧，这样，可以进一步减小显示面板100的厚度尺寸。
如图4所示，在本公开的一个实施例中，显示液晶面板1还包括第二偏光片12，该第二偏光片12位于显示液晶面板1的远离调光液晶面板2的一侧，其偏光方向与第一偏光片11的偏光方向正交。第二偏光片12的雾化度可以设计为15％～30％，例如，第二偏光片12的雾化度为25％。这样可以进一步减弱支撑单元32对显示面板的光学影响，进一步提升显示面板的光学均一性。
如图5所示，本公开实施例还提供一种显示装置，包括前述任一实施例的显示面板100。与相关技术相比，该显示装置的画面显示品质更高，功耗更低，厚度更薄，重量更轻，从而显著提升了用户体验。显示装置的具体产品类型不限，例如可以为显示器、平板电脑、笔记本电脑、电视机、ATM设备、电子纸、展示屏等等。
如图6所示，本公开实施例还提供一种显示面板的制作方法，包括以下步骤S1和步骤S2。
在步骤S1，在调光液晶面板的出光侧或者在显示液晶面板的入光侧形成框胶。
在步骤S2，将调光液晶面板和显示液晶面板对位并通过框胶粘接。
在本公开的一些实施例中，显示面板的制作方法，在步骤S2之前，还包括：在调光液晶面板的出光侧或者在显示液晶面板的入光侧形成多个支撑单元，支撑单元的设置位置满足：在垂直于显示液晶面板的方向上，支撑单元处于显示液晶面板的遮光矩阵的遮光区域内；和/或，在垂直于调光液晶面板的方向上，支撑单元处于调光液晶面板的遮光矩阵的遮光区域内。
其中，形成多个支撑单元的步骤可以在步骤S1之前进行，也可以在步骤S1之后，步骤S2之前进行。
在本公开的一些实施例中，支撑单元与框胶的材料相同，可以共同形成在调光液 晶面板的表面或者共同形成在显示液晶面板的表面。关于支撑单元和框胶的参数设计、材料选择等可参考前述关于显示面板的实施例的描述，这里不再重复赘述。
在本公开的一些实施例中，框胶呈闭合框形状，调光液晶面板和显示液晶面板的对位和粘接是在真空环境中进行。
如图7所示，在本公开的另一个实施例中，显示面板的制作方法包括了以下步骤S101-步骤S111。
步骤S101：提供一调光液晶面板和一显示液晶面板。
步骤S102：在调光液晶面板的出光侧形成框胶和支撑单元。
步骤S103：在真空环境中，将调光液晶面板和显示液晶面板对位、粘接。
步骤S104：对框胶和支撑单元进行固化。根据具体材料不同，可以对框胶和支撑单元进行热固化或者自然固化，以提高其粘接强度和形态稳定性。
步骤S105：对框胶与调光液晶面板和显示液晶面板的粘接进行脱泡处理，例如采用真空脱泡工艺进行脱泡处理，以进一步提高粘接的强度。
步骤S106：对完成上述步骤的组件进行封边处理，以提高边缘密封性。
采用本公开上述实施例制作方法制作的显示面板，相比相关技术，可以有效改善显示画面的条纹、彩虹纹和色偏等现象，并且有利于降低显示装置的功耗，减小显示装置的厚度和重量。
至此，已经详细描述了本公开的各实施例。为了避免遮蔽本公开的构思，没有描述本领域所公知的一些细节。本领域技术人员根据上面的描述，完全可以明白如何实施这里公开的技术方案。
