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，尤其涉及一种曲面显示面板与曲面显示装置。
背景技术
曲面显示装置整片屏幕呈弧形的设计，与弧形的人眼构造相吻合，从人体工学上讲更符合人眼的设计，同时可提供宽阔的全景影像效果，不论是在屏幕中央还是边缘四周，都能够带来同样的视觉享受，并且在近距离观看时还减少了离轴观看的失真度，还能为人眼带来更舒适的感觉，提供沉浸式的观影体验。
曲面显示面板是曲面显示装置的核心组成部分。曲面显示面板的制程过程为：先完成制作平面状态的显示面板，再通过物理弯曲或其它相关或相类似的施力方式，将此平面状态的显示面板弯曲，形成曲面显示面板。
曲面显示面板处于平面状态时，对向基板上的间隔柱的位置大致对应阵列基板显示区的主动开关的位置。但当对该液晶面板进行弯曲，使其处于曲面状态时，由于曲面液晶面板具有一定的弧度，再加上玻璃基底应力的关系，弯曲后的对向基板与阵列基板之间会产生相对滑动，造成显示面板的两相对基板错位。从而导致视觉上的暗团，光学品味下降。
申请内容
本申请一目的在于提供一种曲面显示面板，包括但不限于解决平面状态的显示面板弯曲形成曲面显示面板后，曲面显示面板的两基板之间的间隔空间厚度不等，从而导致曲面显示面板的显示质量差。
本申请实施例采用的技术方案是：提供一种曲面显示面板，包括：第一基 板，包括显示区及环设其周边的边框区，设于所述显示区上的阵列结构，所述阵列结构包括多个主动开关和多个像素单元，所述多个像素单元分别耦接于所述多个主动开关，所述多个主动开关电性耦接于多个数据线与多个扫描线的交集处；第二基板，与所述第一基板对向设置；多个间隔柱，设置于所述第二基板，定义所述第一基板与所述第二基板之间的间隔空间；其中，在平面状态下，在所述显示区的所述多条数据线的排列方向上，所述多个间隔柱中的本列间隔柱与所述多个主动开关中的本列主动开关的排列顺序相同，所述本列间隔柱与所述本列主动开关的位置相重合时，相邻列间隔柱之间的第一间隔，与相邻列开关之间的第二间隔相差一偏移距离；在曲面状态下，所述多个间隔柱与所述多个主动开关的位置相重合。
本申请的另一目的在于提供一种曲面显示装置，包括：控制模块；第一基板，包括显示区及环设其周边的边框区，设于所述显示区上的阵列结构，所述阵列结构包括多个主动开关和多个像素单元，所述多个像素单元分别耦接于所述多个主动开关，所述多个主动开关电性耦接于多个数据线与多个扫描线的交集处；第二基板，与所述第一基板对向设置；多个间隔柱，设置于所述第二基板，定义所述第一基板与所述第二基板之间的间隔空间；其中，在平面状态下，在所述显示区的所述多条数据线的排列方向上，所述多个间隔柱中的本列间隔柱与所述多个主动开关中的本列主动开关的排列顺序相同，所述本列间隔柱与所述本列主动开关的位置相重合时，相邻列间隔柱之间的第一间隔，与相邻列开关之间的第二间隔相差一偏移距离；在曲面状态下，所述多个间隔柱与所述多个主动开关的位置相重合。
本申请实施例可以在不大幅改变现有生产流程的前提下，通过提前对间隔柱偏移设计，避免曲面状态下的间隔柱与主动开关错位，较能使两基板之间的 间隔空间维持相等厚度，降低曲面显示面板左右两侧区域与中间区域的亮度差异问题，减少视觉上的暗团，从而提升曲面显示面板的显示质量与光学品味。

为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。
图1a为范例性的曲面显示面板的平面状态横截面示意图。曲面显示面板基本结构包括第一基板100、第二基板200与液晶层30。第一基板100，其包括显示区及环设其周边的边框区，阵列结构110设置于显示区，阵列结构110包括多个主动开关112和多个像素单元，多个像素单元分别耦接于多个主动开关112，多个主动开关112电性耦接于多个数据线与多个扫描线的交集处。第二基板200，与第一基板100对向设置，第二基板200包括多个像素区域，与第一基板100的像素单元相对应。多个间隔柱204设置于第一基板100与第二基板200之间，用以定义第一基板100与第二基板200之间的间隔空间。液晶层30则设于间隔空间中。
在一个实施例中，该曲面显示面板还包括彩色滤光层400，该彩色滤光层400可以设置于第一基板100或者第二基板200上。
曲面显示面板的制程过程为：先完成制作平面状态的显示面板，再通过物理弯曲或其它相关或相类似的施力方式，将此平面状态的显示面板弯曲，形成曲面显示面板。
图1b为范例性的曲面显示面板朝向第二基板侧弯曲示意图，图1c与1d为范例性的间隔柱向外偏移示意图。图1e为范例性的曲面显示面板朝向第一基板侧弯曲示意图，图1f与图1g为范例性的间隔柱向外偏移示意图。曲面显示面板处于平面状态时，第二基板200上的间隔柱204的位置大致对应第一基板100显示区的主动开关112的位置。但当对该液晶面板进行弯曲，使其处于曲面状态时，由于曲面液晶面板具有一定的弧度，再加上玻璃基底应力的关系，弯曲后的第二基板200与第一基板100之间会产生相对滑动，造成显示面板的两相对基板错位。如图1c与1d，第二基板200以其中心为基点，其左侧相对于第一基板100向左偏移，其右侧相对于第一基板100向右偏移；或如图1f与图1g，第二基板200以其中心为基点，其左侧相对于第一基板100向右偏移，其右侧相对于第一基板100向左偏移。不论是图1b或图1c，都会造成间隔柱204的位置不再对应主动开关112的位置，而是相对于曲面显示面板的径向产生了错位。
如此，曲面显示面板的左右两侧偏移量较大的区域，与曲面显示面板中间偏移量较小(或无偏移量)的区域，两部位的面板封装盒厚不相等，中间部位盒厚为d1+d2，两侧的盒厚为d1-d2，，造成两基板之间的间隔空间不再保持相等厚度，这样就会出现曲面显示面板左右两侧区域与中间区域的亮度有差异，从而导致视觉上的暗团，光学品味下降。
图2a为显示本申请一实施例的曲面显示面板的偏移距离示意图。图2b为显示本申请一实施例的曲面显示面板的弯曲变化示意图。图2c为显示图2b 曲面显示面板的中央部位状态变化示意图。图2d为显示图2b曲面显示面板的左侧部位状态变化示意图。图2e为显示图2b曲面显示面板的右侧部位状态变化示意图。在本申请一实施例中，一种曲面显示面板，包括：第一基板100与第二基板200。第一基板100包括显示区及环设其周边的边框区，阵列结构110设置于显示区，阵列结构110包括多个主动开关112和多个像素单元，多个像素单元分别耦接于多个主动开关112，多个主动开关112电性耦接于多个数据线与多个扫描线的交集处。第二基板200与第一基板100对向设置。多个间隔柱204，设置于第二基板200，在第一基板100与第二基板200组装时，定义第一基板100与第二基板200之间的间隔空间。其中，在平面状态下，显示区中心纵线C为始，所述多条数据线的排列方向上，多个间隔柱204中的本列间隔柱2041与多个主动开关112中的本列主动开关1121的排列顺序相同，本列间隔柱2041与本列主动开关1121的位置相重合时，相邻列间隔柱(即本列间隔柱2041与次列间隔柱2042)之间的第一间隔L1，与相邻列开关(本列主动开关1121与次列主动开关1122)之间的第二间隔L2相差一偏移距离X；在曲面状态下，多个间隔柱204与多个主动开关112的位置相重合。
在一个实施例中，该曲面显示面板还包括彩色滤光层400，该彩色滤光层400可以设置于第一基板100或者第二基板200上。
在一个实施例中，第一基板100为阵列基板，第二基板200为对向基板。
在一个实施例中，曲面显示面板朝向第二基板200侧弯曲，在平面状态时，第一间隔L1为第二间隔L1与偏移距离X的和值，即L1＝L2+X。
在一个实施例中，曲面显示面板预定朝向第二基板200侧弯曲时，多个间隔柱204朝向显示区中心纵线C方向偏移X。
在一个实施例中，不同位置的所述多个间隔柱204对应的偏移距离X为相 同、相异或局部相同。
如图2c，在一个实施例中，中央部位的多个间隔柱204与其位置相对应的多个主动开关112之间，偏移距离X较小，或无偏移量，在面板弯曲后，两基板中间部位的多个间隔柱204与多个主动开关112仍是位置相对应。
如图2d与图2e，在一个实施例中，在平面状态下，第二基板200左侧的每一间隔柱204向右(即朝向显示区中心纵线C方向)偏移X，第二基板200右侧的每一间隔柱204向左(即朝向显示区中心纵线C方向)偏移X。面板弯曲后，令第二基板200左侧相对于第一基板100向左偏移X，右侧相对于第一基板100向右偏移X。多个间隔柱204与多个主动开关112的位置相重合。

在一个实施例中，曲面显示面板朝向第一基板100侧弯曲，在平面状态时，第二间隔L2为第一间隔L1与偏移距离X的和值，即L2＝L1+X。
在一个实施例中，曲面显示面板预定朝向第一基板100侧弯曲时，在平面状态下，多个间隔柱204背向显示区中心纵线C方向偏移X，或者，多个主动开关朝向显示区中心纵线C方向偏移X。
在一个实施例中，中央部位的所述多个间隔柱204与其位置相对应的多个主动开关112之间，偏移距离X较小，或无偏移量，所以在面板弯曲后，两基板中间部位的多个间隔柱204与多个主动开关112仍是位置相对应。
如图3c与图3d，在一个实施例中，在平面状态下，第二基板200左侧的多个间隔柱204向左(即背向显示区中心纵线C方向)偏移X，第二基板200右 侧的多个间隔柱204向右(即背向显示区中心纵线C方向)偏移X。面板弯曲后，第二基板200左侧相对于第一基板100向右偏移X，右侧相对于第一基板100向左偏移X。多个间隔柱204与多个主动开关112的位置相重合。
在一个实施例中，间隔柱204是依据与显示区中心纵线之间的距离、其所对应的主动开关112、间隔柱204所属列数、对应的主动开关112、曲面显示面板的弯曲方向，第二基板200的预设弯曲半径、所在位置的预定弯曲系数等至少一者，预先偏移X。
在一个实施例中，多个数据线为等间距排列。
在一个实施例中，在平面状态下，第一间隔L1与第二间隔L2为等比例关系。
在一个实施例中，曲面显示面板朝向第二基板200侧弯曲，等比例关系为L1：L2＝(R+d)：R，其中，L1为第一间隔，L2为第二间隔，R为第二基板200的预设弯曲半径，d为间隔空间的厚度。
在一个实施例中，曲面显示面板朝向第一基板100侧弯曲，等比例关系为L1：L2＝(R+d)：R，其中，L1为第一间隔，L2为第二间隔，R为第二基板200的预设弯曲半径，d为间隔空间的厚度。
在一个实施例中，第二基板200还包括遮光层206，遮光层206设置于多个间隔柱204正上方。
在一个实施例中，遮光层206包括黑色矩阵。
在一个实施例中，在曲面状态下，曲面液晶面板的开口区与遮光区垂直相对，第一基板100与第二基板200的像素区域相匹配。
在一个实施例中，遮光区包括第二基板200的遮光层206与第一基板100的多个数据线的走线处。
在一个实施例中，第二基板200的预设弯曲半径R为处于曲面状态下的第二基板200的圆心到其邻接间隔空间一侧表面的距离。
在一个实施例中，曲面显示面板还包括液晶层30，位于第一基板100以及第二基板200之间。
在一个实施例中，显示区中心纵线C为始，由内往外画分多个显示区域，其中，每一显示区域对应的偏移距离X为相同、相异或局部相同。
在一个实施例中，相邻的两显示区域，内显示区域对应的偏移距离小于或等于外显示区域对应的偏移距离X。
在一个实施例中，显示区中心纵线C为始，由内往外画分多个显示区域，在平面状态下，多个显示区域对应的第一间隔L1与第二间隔L2，其等比例关系为相同、相异或局部相同。
在一个实施例中，偏移距离X可以依据间隔柱204与主动开关112的实际位置而各别被设计。如此，设计人员较为自由的调整曲面显示面板不同部位的弯曲度，设计上更为弹性。
在一个实施例中，曲面显示面板朝向第二基板200侧弯曲时，相邻的两显示区域，内显示区域对应的等比例关系小于或等于外显示区域对应的等比例关系。
在一个实施例中，曲面显示面板朝向第一基板100侧弯曲时，相邻的两显示区域，内显示区域对应的等比例关系大于或等于外显示区域对应的等比例关系。
在本申请一实施例中，一种曲面显示装置，包括：控制模块(图未示)；以及前述的曲面显示面板。
本申请可以在不大幅改变现有生产流程的前提下，通过提前对间隔柱偏移 设计，避免曲面状态下的间隔柱与主动开关错位，较能使两基板之间的间隔空间维持相等厚度，降低曲面显示面板左右两侧区域与中间区域的亮度差异问题，减少视觉上的暗团，从而提升曲面显示面板的显示质量与光学品味。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
