Description

曲面显示面板及曲面显示装置 技术领域
本申请涉及显示技术领域，具体涉及一种曲面显示面板及曲面显示装置。
 背景技术
液晶显示装置因具有轻薄、能耗小、无辐射等优点而广泛应用于多种显示设备中。液晶显示面板通常包括相对设置的阵列基板和彩膜基板以及夹在阵列基板和彩膜基板之间的液晶，在阵列基板和彩膜基板之间通常还会设置支撑柱，用以支撑阵列基板和彩膜基板，在彩膜基板侧会涂布黑矩阵以改善漏光与对比度。
 技术问题
对于中大尺寸的液晶显示面板，例如车载用的液晶显示面板，数据线与黑矩阵的位置为居中关系，在制造曲面屏时，由于屏幕弯曲时阵列基板的曲率和彩膜基板的曲率不同，使得黑矩阵与金属走线发生错位，导致屏幕发生漏光，影响对比度，严重影响显示装置的显示效果。现有解决方案为将液晶显示面板划分为左右两个显示区域，左侧显示区域内黑矩阵的中心线相对于数据线的中心线偏左，右侧显示区域内黑矩阵的中心线相对于数据线的中心线偏右，此方案可有效改善漏光与对比度。然而，在上述技术方案中，靠近中心线的子像素的开口率与远离中心线的子像素的开口率的差异较大，导致面板中间存在开口率突变区域，使得面板产生分屏现象，降低了曲面显示面板的显示效果。

本申请提供一种曲面显示面板。所述曲面显示面板包括多个子像素，曲面显示面板具有中线和中心显示区，中心显示区关于中线对称，自远离中线至朝向中线的方向，位于中心显示区内的子像素的开口率逐渐增大，且相邻两个子像素的开口率的差值小于或等于2%。
由此，在本申请提供的曲面显示面板中，自曲面显示面板的中线至朝向所述中线的方向，位于曲面显示面板的中心显示区的子像素的开口率逐渐增大，且相邻两个子像素的开口率的差值小于或等于2%。在上述设置下，本申请降低了中心显示区内的相邻子像素的开口率的差异，进而能够降低曲面显示面板的分屏几率，从而有利于提高曲面显示面板的显示效果。
请参照图1至图3，现有技术中的曲面显示面板100’包括相对设置的阵列基板10’和彩膜基板20’。阵列基板10’包括多条数据线11’和多条扫描线12’。多条数据线11’沿第一方向Y’延伸且沿第二方向X’排布。每一数据线11’具有沿第一方向Y’延伸的第一中心线11a’。多条扫描线12’沿第二方向X’延伸且沿第一方向Y’排布。多条数据线11’和多条扫描线12’交叉形成多个子像素13’。彩膜基板20’包括黑矩阵21’。黑矩阵21’覆盖数据线11’和扫描线12’。黑矩阵21’包括多个黑矩阵部211’。一黑矩阵部211’对应覆盖一数据线11’。每一黑矩阵部211’具有沿第一方向Y’延伸的第二中心线21a’。曲面显示面板100’具有一中线10a’。中线10a’沿第一方向Y’延伸。在非弯曲状态下，自中线10a’至远离中线10a’的方向，第一中心线11a’和对应的第二中心线21a’在第二方向X’上的间距n’相等。
在上述曲面显示面板100’中，在中线10a’位置处，第一中心线11a’和对应的第二中心线21a’在第二方向X’上的距离为零，也即，中线10a’位置处的黑矩阵部211’相较于数据线11’无偏离；自中线10a’至远离中线10a’的方向，第一中心线11a’和对应的第二中心线21a’在第二方向X’上的间距n’相等，也即，黑矩阵部211’相较于数据线11’的偏离程度相同。
其中，子像素13’所在区域内未被黑矩阵21’覆盖的区域为像素开口区（图中未标识）。每一子像素13’对应像素开口区均具有一开口率。当多个黑矩阵部211’在第一方向Y’上的长度相同时，相邻子像素13’的像素开口率之间的大小关系等同于相邻黑矩阵部211’之间距离的大小关系。
请继续参照图2，位于中线10a’位置处的黑矩阵部211’与相邻两个黑矩阵部211’之间的距离为L0’，且自中线10a’至远离中线10a’的方向，每相邻两个黑矩阵部211’之间的距离为L1’，L0’>L1’。以中线10a’为曲面显示面板100’的对称轴，位于中线10a’位置处的黑矩阵部211’与相邻两个黑矩阵部211’之间的区域为中心显示区10A’，进一步的，曲面显示面板100’还包括位于中心显示区10A’一侧的左侧显示区10B’和位于中心显示区10A’另一侧的右侧显示区10C’。
结合图3，由于L0’>L1’，也即，中心显示区10A’内子像素13’的开口率大于左侧显示区10B’和右侧显示区10C’内子像素13’的开口率，且左侧显示区10B’和右侧显示区10C’内子像素13’的开口率均相同，由此可以看出，由于像素开口率在中心显示区10A’会发生突变，进而会导致面板产生分屏现象，从而会大大降低曲面显示面板100’的显示效果。
进一步的，针对现有技术中存在的上述技术问题，本申请提供一种曲面显示面板。曲面显示面板包括相对设置的阵列基板和彩膜基板。阵列基板包括多条沿第一方向延伸且沿第二方向排布的数据线，多条数据线包括多条第一数据线，每一第一数据线具有沿第一方向延伸的第一中心线；彩膜基板包括多个第一黑矩阵部，一第一黑矩阵部对应覆盖于一第一数据线，每一第一黑矩阵部具有沿第一方向延伸的第二中心线；其中，中线沿第一方向延伸，至少四条第一数据线位于中心显示区并关于中线对称；在非弯曲状态下，在中心显示区，第一中心线和对应的第二中心线在第二方向上具有第一预设距离，自远离中线至朝向中线的方向，第一预设距离逐渐减小。
由此，在本申请提供的曲面显示面板的中心显示区，在非弯曲状态下，自远离曲面显示面板的中线至朝向所述中线的方向，通过使第一数据线的中心线和第一黑矩阵部的中心线之间的距离逐渐减小，也即，第一黑矩阵部相对于第一数据线的偏离程度逐渐减小，由此使得中心显示区的像素开口率逐渐增大，因而通过像素开口率的渐变式设计，能够避免曲面显示面板在中心显示区出现开口率突变现象，从而降低了曲面显示面板的分屏几率，提高了曲面显示面板的显示效果。
下面通过具体实施例对本申请提供的曲面显示面板进行详细的阐述。
请参照图4和图5，本申请第一实施例提供一种曲面显示面板100。曲面显示面板100包括相对设置的阵列基板10、彩膜基板20以及设置在阵列基板10和彩膜基板20之间的液晶层（图中未示出）。
阵列基板10包括多条数据线11和多条扫描线12。多条数据线11沿第一方向Y延伸且沿第二方向X排布。多条数据线11包括多条第一数据线111。每一第一数据线111具有沿第一方向Y延伸的第一中心线111a。多条扫描线12沿第二方向X延伸且沿第一方向Y排布。
彩膜基板20包括黑矩阵21。黑矩阵21覆盖数据线11和扫描线12。黑矩阵21包括多个第一黑矩阵部211。一第一黑矩阵部211对应覆盖于一第一数据线111。每一第一黑矩阵部211具有沿第一方向Y延伸的第二中心线211a。
其中，曲面显示面板100具有中线10a。中线10a沿第一方向Y延伸。可以理解的是，中线10a即为曲面显示面板100的中心轴。对于应用曲面显示面板100的曲面屏，中线10a所在位置即为曲面屏的屏幕中心线。进一步的，当曲面显示面板100处于弯曲状态时，中线10a为曲面显示面板100的弯折线。
在本实施例中，位于中心显示区10A内的数据线11的数量为奇数。其中，多条数据线11还包括一第二数据线112。第二数据线112具有沿第一方向Y延伸的第三中心线112a。第三中心线112a与中线10a在第二方向X上的间距为零，从俯视角度看，第三中心线112a与中线10a重合。对应的，黑矩阵21还包括一第二黑矩阵部212。第二黑矩阵部212具有沿第一方向Y延伸的第四中心线212a。第四中心线212a与第三中心线112a在第二方向X上的间距为零，从俯视角度看，第四中心线212a与第三中心线112a重合。也即，在中线10a位置处，第二黑矩阵部212相较于第二数据线112没有发生偏离。
进一步的，曲面显示面板100还具有中心显示区10A和位于中心显示区10A相对两侧并关于中线10a对称的非中心显示区10B。其中，中心显示区10A关于中线10a对称。可以理解的是，对于应用曲面显示面板100的曲面屏，中心显示区10A即为曲面屏的屏幕中心区域，位于中心显示区10A一侧的非中心显示区10B为曲面屏的左侧显示区，位于中心显示区10A另一侧的非中心显示区10B为曲面屏的右侧显示区。在本实施例中，至少四条第一数据线111位于中心显示区10A并关于中线10a对称。
在非弯曲状态下，在中心显示区10A，第一中心线111a和对应的第二中心线211a在第二方向X上具有第一预设距离。自远离中线10a至朝向中线10a的方向，第一预设距离逐渐减小，结合图5，n1<n2<n3。也即，在中心显示区10A中位于中线10a任一侧的区域，第一黑矩阵部211相较于第一数据线111具有不同的偏离程度，具体来说，自远离中线10a至靠近中线10a的方向，第一黑矩阵部211相较于第一数据线111的偏离程度逐渐减小。
进一步的，至少六条第一数据线111位于中心显示区10A。自中线10a至远离中线10a的方向，第一预设距离构成等差数列，即(n2-n1)=(n3-n2)。需要说明的是，位于中心显示区10A的第一数据线111的数量可以根据面板分辨率的需求进行设定，本申请对此不作限定，只要保证第一数据线111的数量为至少四条，均在本申请的保护范围内。
在本实施例中，多条数据线11和多条扫描线12交叉形成多个子像素13。子像素13所在区域内未被黑矩阵21覆盖的区域为像素开口区（图中未标识）。每一子像素13对应像素开口区均具有一开口率。其中，子像素13包括位于中心显示区10A的第一子像素131。
在本实施例中，多个第一黑矩阵部211在第一方向Y上的长度相同，相邻第一子像素131的开口率之间的大小关系反比于相邻第一黑矩阵部211间距的大小关系。具体的，自远离中线10a至靠近中线10a的方向，当第一黑矩阵部211相较于第一数据线111的偏离程度逐渐减小时，第一子像素131的开口率逐渐增大。其中，为了提高面板的显示均一性，避免相邻第一子像素131的开口率差异过大，每相邻两个第一子像素131的开口率的差值均维持为2%以内。
进一步的，自远离中线10a至朝向中线10a的方向，中心显示区10A内第一子像素131的开口率构成等差数列，由此可以实现中心显示区10A内显示亮度的均匀过渡，有助于提高面板在中心显示区10A的亮度均一性。
结合图5，在本实施例中，每相邻两条数据线11的间距d相等。在第二方向X上，第二黑矩阵部212与相邻的第一黑矩阵部211之间具有一中心距离L0。中心距离L0大于相邻两个第一黑矩阵部211的间距。自远离中线10a至朝向中线10a的方向，相邻两个第一黑矩阵部211的间距逐渐增大。具体的，以中心显示区10A内第一数据线111的数量为六条为例，自中线10a至远离中线10a的方向，相邻两个第一黑矩阵部211的间距依次为L1和L2，L0>L1>L2。
进一步的，结合图6，在中心显示区10A，自远离中线10a至朝向中线10a的方向，第一子像素131的开口率逐渐增大，因而相较于现有技术中的像素开口率突变，上述像素开口率的渐变式设计能够有效避免开口率突变现象的发生，从而能够显著降低曲面显示面板100的分屏几率，以提高曲面显示面板100的显示效果。
在非弯曲状态下，在非中心显示区10B，第一中心线111a和对应的第二中心线211a在第二方向X上具有第二预设距离m。第二预设距离m大于第一预设距离。自远离中线10a至朝向中线10a的方向，第二预设距离m不变。也即，在本实施例的非中心显示区10B，第一黑矩阵部211相较于第一数据线111的偏离程度相同，对应的，结合图6，第二子像素132的开口率相同。
由此，在本实施例中，通过在曲面显示面板100的中心显示区10A进行像素开口率渐变式设计，并维持非中心显示区10B的像素开口率一致，能够在降低面板分屏几率的同时，提高曲面显示面板100的实用性。
结合图7，在曲面显示面板100处于弯曲状态时，自远离中线10a至朝向中线10a的方向，位于中心显示区10A内的第一子像素131的开口率逐渐增大，且相邻两个第一子像素131的开口率的差值小于或等于2%。具体的，所述差值可以为0.2%、0.5%、0.8%、1.0%、1.2%、1.5%、1.8%或2%，所述差值的具体大小可以根据实际应用需求进行设定，本申请对此不作限定。
另外，在本实施例中，在曲面显示面板100处于弯曲状态时，位于非中心显示区10B内的第二子像素132的开口率相同。
进一步的，在曲面显示面板100处于弯曲状态下时，在中心显示区10A和非中心显示区10B，第一中心线111a和对应的第二中心线211a在第二方向X上的间距均为零。也即，在整个曲面显示面板100中，第一黑矩阵部211相较于第一数据线111均没有发生偏离。请参照图8，第一黑矩阵部211与对应的第一数据线111之间没有错位。因此，本实施例能够避免因第一黑矩阵部211和第一数据线111之间错位而发生漏光现象，从而可以保证曲面显示面板100的对比度不受影响，有利于提高曲面显示面板100的显示质量。
综上，在本申请第一实施例提供的曲面显示面板100中，在非弯曲状态下，自远离曲面显示面板100的中线10a至朝向所述中线10a的方向，通过使中心显示区10A内第一数据线111的中心线和第一黑矩阵部211的中心线之间的距离逐渐减小，也即，第一黑矩阵部211相对于第一数据线111的偏离程度逐渐减小，使得中心显示区10A的像素开口率逐渐增大。因而，通过在中心显示区10A对像素开口率进行渐变式设计，能够在保证面板对比度不受影响的同时，降低曲面显示面板100的分屏几率，从而能够大大提高曲面显示面板100的显示效果。此外，由于本实施例中非中心显示区10B的像素开口率保持不变，因此有利于提高曲面显示面板100的实用性。
请参照图9和图10，本申请第二实施例提供一种曲面显示面板100。本申请第二实施例提供的曲面显示面板100与第一实施例的不同之处在于：位于中心显示区10A内的数据线11的数量为偶数，在第二方向X上，与中线10a相邻的两个第一黑矩阵部211之间具有中心距离L0，自中线10a至远离中线10a的方向，中心距离L0大于相邻两个第一黑矩阵部211的间距。
请参照图11至图14，本申请第三实施例提供一种曲面显示面板100。本申请第三实施例提供的曲面显示面板100与第一实施例的不同之处在于：自远离中线10a至朝向中线10a的方向，第二预设距离逐渐减小。
结合图12，m2>m1，也即，在本实施例的非中心显示区10B，第一黑矩阵部211相较于第一数据线111的偏离程度不同。具体来说，自远离中线10a至朝向中线10a的方向，第一黑矩阵部211相较于第一数据线111的偏离程度逐渐减小。对应的，结合图13，自远离中线10a至朝向中线10a的方向，第二子像素132的开口率逐渐增大。
由此，本实施例通过在曲面显示面板100的中心显示区10A及非中心显示区10B同时进行像素开口率渐变设计，从而能够显著降低曲面显示面板100的分屏几率，进而提高曲面显示面板100的显示效果。
在本实施例中，在非中心显示区10B，自中线10a至远离中线10a的方向，第二预设距离构成等差数列。进一步的，在中心显示区10A和非中心显示区10B，自中线10a至远离中线10a的方向，第一中心线111a和对应的第二中心线211a在第二方向X上的间距构成等差数列。也即，自中线10a至远离中线10a的方向，相邻第一黑矩阵部211相较于相邻第一数据线111的偏离程度的变化值相同，故而自远离中线10a至朝向中线10a的方向，每相邻两个子像素13的开口率的差值相等。上述设置使得子像素13的开口率呈现规律性变化，从而有利于提高曲面显示面板100的亮度均一性。
进一步的，在本实施例中，在曲面显示面板100处于弯曲状态时，自远离中线10a至朝向中线10a的方向，位于非中心显示区10B内的第二子像素132的开口率逐渐增大，在非中心显示区10B和中心显示区10A，任意相邻两个子像素13的开口率的差值均小于或等于2%。上述设置可以提高曲面显示面板100的亮度均一性。
请参照图15和图16，本申请第四实施例提供一种曲面显示面板100。本申请第四实施例提供的曲面显示面板100与第三实施例的不同之处在于：位于中心显示区10A内的数据线11的数量为偶数，在第二方向X上，与中线10a相邻的两个第一黑矩阵部211之间具有中心距离L0，自中线10a至远离中线10a的方向，中心距离L0大于相邻两个第一黑矩阵部211的间距。
本申请还提供一种曲面显示装置，所述曲面显示装置可以为车载显示器、电视或商用显示产品等。其中，所述曲面显示装置包括曲面显示面板，所述曲面显示面板可以为前述任一实施例所述的曲面显示面板100，曲面显示面板100的具体结构可以参照前述实施例的描述，在此不再赘述。
以上对本申请实施例所提供的一种曲面显示面板及曲面显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上，本说明书内容不应理解为对本申请的限制。
