为清楚地表述本申请的方案，对本申请一些名词解释如下：
凸起底面的中心点：当凸起底面为圆形时，凸起底面的中心点为圆形的圆心；当凸起底面为多边形时，凸起底面的中心点为多边形外接圆的圆心。
凸起底面的尺寸：当凸起底面为圆形时，凸起底面的尺寸为圆形的半径；当凸起底面为多边形时，凸起底面的尺寸为多边形外接圆的半径。
本申请中，在第一方向上，多个凸起的顶点位置逐渐发生变化，该变化可以是凸起的顶点高度的变化，也可以是凸起的顶点在凸起底面投影的位置变化，第一方向可以是多个凸起的阵列方向，也可以是为纹理层所在的平面内的任一方向。具体的，请再次参阅图8，图8为本申请一实施例提供的凸起11的立体结构示意图，其中，凸起11的顶点高度h指的是凸起11的顶点111到凸起底面112的距离，凸起11的顶点高度h的变化指的是多个凸起11在第一方向上的顶点高度h的逐渐变化，逐渐变化可以是逐渐增大或逐渐减小，或是先增大再减小、或是先减小再增大。请参阅图9，图9为本申请一实施例提供的凸起底面112结构示意图，图9中，凸起底面112的中心点O为凸起底面112外接圆110的圆心，凸起11的顶点在凸起底面112的投影点为H，凸起11的顶点在凸起底面112投影点H相对凸起底面112中心点O的距离为d，凸起11的顶点在凸起底面112投影点H相对凸起底面112的中心点O的位置变化指的是凸起11的顶点在凸起底面112的投影点H与凸起底面112的中心点O的距离逐渐变化，该逐渐变化可以是逐渐增大或逐渐减小，或是先增大再减小、或是先减小再增大。本申请通过设定凸起阵列中凸起结构的变化可以实现纹理层在不同角度下的多层次变化，定向排布的凸起使得颜色渐变更加自然，从而实现装饰基板立体的渐变效果。
本申请一些实施方式中，在第一方向上，多个凸起的顶点在凸起底面的投影点相对凸起底面的中心点的距离逐渐变化。需要注意的是，本申请中，纹理层中多个凸起底面图形相同或相似，故不同的凸起中，凸起底面的中心点位置是相同的。请参阅图10，图10为本申请一实施例提供的凸起结构变化示意图，图10中，凸起底面为四边形，凸起的结构为四棱锥，四棱锥顶点在底面的投影位置发生变化，使得四棱锥的结构也相应变化。请参阅图11，图11为本申请一实施例提供的凸起结构变化示意图，图11中，凸起底面为五边形，凸起的结构为五棱锥，五棱锥顶点在底面的投影位置发生变化，使得五棱锥的结构也相应变化。请参阅图12，图12为本申请一实施例提供的凸起结构变化示意图，图12中，凸起底面为六边形，凸起的结构为六棱锥，六棱锥顶点在底面的投影位置发生变化，使得六棱锥的结构也相应变化。凸起顶点相对凸起底面中心点的位置变化可以改变凸起侧面的角度和尺寸，使得光线在纹理层中不同位置反射出不同强度的光，呈现出明暗的变化，且散射出不同的颜色，呈现出渐变色的效果。
本申请中，多个凸起的顶点在凸起底面的投影点相对凸起底面的中心点的距离逐渐变化可以理解为，多个凸起的顶点在凸起底面的投影点逐渐靠近或逐渐远离凸起底面的中心点，在多个凸起顶点位置变化的方向上(即第一方向)，将多个凸起的顶点在凸起底面的投影点连接后得到凸起顶点的排布路径，该排布路径可以是直线路径和曲线路径中的至少一者。请参阅图13A和图13B，图13A为本申请一实施例提供的多个凸起A1、A2和A3的排布示意图，图13B为图13A中的多个凸起A1、A2和A3的顶点111在凸起底面112的投影点H1、H2、H3的位置变化的结构示意图。其中，多个凸起A1、A2和A3对应的多个凸起底面112均为四边形，第一方向X为多个凸起A1、A2和A3的阵列方向。在第一方向X上，多个凸起A1、A2和A3的顶点在凸起底面112的投影点H1、H2和H3沿四边形的对角线P依次排布设置。请参阅图14A和图14B，图14A为本申请另一实施例提供的多个凸起A1、A2和A3的排布示意图，图14B为图14A中的多个凸起A1、A2和A3的顶点在凸起底面112的投影点H1、H2和H3的位置变化的结构示意图，其中，多个凸起A1、A2和A3对应的多个凸起底面112均为四边形。示例性地，在本实施例中，四边形包括长度相同的四条边长113。在一些实施例中，四边形还可以包括长度不同的四条边长113。定义预设线段l1为平行于四边形的边长113的线段， 在第一方向X上，多个凸起A1、A2和A3的顶点沿预设线段l1移动。示例性地，在本实施例中，预设线段l1位于凸起底面112内。在一些实施例中，预设线段l1还可以至少部分位于凸起底面112内。
本申请一些实施方式中，在第一方向上，多个凸起的顶点在凸起底面的投影点都落在凸起底面的过凸起底面的中心点的同一条轴上，过凸起底面的中心点的轴例如可以是凸起底面的对称轴，也可以是任意过凸起底面的中心点的线段(该线段为凸起底面的周长的任意两点的连线)。也就是说，在第一方向上，将多个凸起的顶点在凸起底面的投影点连接后得到凸起顶点的排布路径，该排布路径与凸起底面的对称轴或过凸起底面中心点的线段相重合。本申请一些实施方式中，凸起底面为多边形，在第一方向上，多个凸起的顶点在凸起底面的投影点都落在平行于凸起底面的多边形的任一边长的同一条线段上(该线段为凸起底面的周长的任意两点的连线)。具有上述结构的凸起阵列排布形成的纹理层可以使装饰基板的颜色过渡较为自然。
本申请一些实施方式中，在第一方向上，多个凸起的顶点在凸起底面的投影点相对凸起底面的中心点的距离逐渐变化，在第一方向上，每1cm的距离内，多个凸起的顶点在凸起底面的投影点相对凸起底面的中心点的距离变化量为1μm～200μm。以图13B为例，在第一方向X上有多个凸起A1、A2和A3，多个凸起A1、A2和A3的顶点在底面112上的投影点H1、H2和H3与凸起底面112的中心点O的距离d1、d2和d3在第一方向X上逐渐减小。例如，凸起A1的顶点在底面112上的投影点H1与凸起底面112中心点O的距离为d1，凸起A2的顶点在凸起底面112上的投影点H2与凸起底面112的中心点O的距离为d2，凸起A3的顶点在凸起底面112上的投影点H3与凸起底面112的中心点O的距离为d3，其中，d1>d2>d3。需要说明的是，凸起A1到凸起A3的距离为1cm(中间可以省略若干凸起)，则凸起的顶点在凸起底面的投影点相对凸起底面的中心点的距离变化量为d1-d3。本申请一些实施例中，第一方向为曲线方向，则1cm的距离指的是弧线段的长度为1cm。
本申请一些实施方式中，在第一方向上，多个凸起的顶点相对凸起底面的高度逐渐变化。请参阅图15A和图15B，图15A为本申请再一实施例提供的多个凸起A1、A2和A3的排布示意图，图15B为图15A中的多个凸起A1、A2和A3的顶点111的高度变化的结构示意图。其中，多个凸起A1、A2和A3对应的多个凸起底面112均为四边形，第一方向X为多个凸起A1、A2和A3的阵列方向。示例性地，在本实施例中，多个凸起A1、A2和A3对应的多个凸起底面112的形状相同，即多个凸起A1、A2和A3对应的多个凸起底面112的中心点O均位于四边形的对角线的交叉处。在一些实施例中，多个凸起A1、A2和A3对应的多个凸起底面112的形状还可以相同。在第一方向X上，多个凸起A1、A2和A3的顶点111相对凸起底面112的高度h1、h2和h3逐渐减小。凸起顶点相对凸起底面高度的变化也可以改变凸起侧面的角度和尺寸，使得光线在纹理层中不同位置反射出不同强度的光，呈现出明暗的变化，且散射出不同的颜色，呈现出渐变色的效果。
本申请一些实施方式中，在第一方向上，多个凸起的顶点相对凸起底面的高度逐渐变化，在第一方向上，每1cm的距离内，凸起的顶点相对凸起底面的高度变化量为0.2μm～6μm，凸起的顶点相对凸起底面的高度变化量具体可以但不限于为0.2μm、0.3μm、0.4μm、0.5μm或0.6μm。请再次参阅图15B，示例性地，在本实施例中，纹理层在第一方向X上具有多个凸起A1、A2和A3，多个凸起A1、A2和A3的高度h1、h2和h3在第一方向X上逐渐减小。例如，凸起A1的顶点111相对凸起底面112的高度为h1，凸起A2的顶点111相对凸起底面112的高度为h2，凸起A3的顶点111相对凸起底面112的高度为h3，其中，h1>h2>h3。需要说明的是，凸起A1到凸起A3的距离为1cm(中间可以省略若干凸起)，则凸起A1和A3的顶点111相对凸起底面112的高度h1和h3的变化量为h1-h3。
本申请一些实施方式中，凸起底面的尺寸为1μm～10mm，凸起底面的尺寸具体可以但不限于为1μm、20μm、50μm、80μm、100μm、200μm、500μm、800μm、1mm、1.5mm、2mm、3mm、5mm、7mm或10mm。当凸起底面为圆形时，凸起底面的尺寸为圆形的半径，即圆形的半径为1μm～10mm；当凸起底面为多边形时，凸起底面的尺寸为多边形外接圆的半径，即多边形外接圆的半径为1μm～10mm。请参阅图16，图16为本申请一实施例提供的纹理层10的结构示意图。在本申请中，相邻凸起11之间的距离d5指的是相邻两个凸起11的两个凸起底面的中心点O的连线长度L1与两个凸起底面的尺寸L2的差值。换句话说，相邻两个凸起11之间的距离d5为凸起底面112之间平面区域的长度。本申请一些实施方式中，相邻两个凸起11之间的距离d5为1μm～10mm，相邻两个凸起11之间的距离d5具体可以但不限于为1μm、20μm、50μm、80μm、100μm、200μm、500μm、800μm、1mm、1.5mm、2mm、3mm、5mm、7mm或10mm。本申请一些实施方式中，凸起底面112的尺寸L2与相邻两个凸起11之间的距离d5的比值为(2～3):1，凸起底面112的尺寸L2与相邻两个凸起11之间的距离d5的比值具体可以但不限于为2:1、2.5:1、2.7:1或3:1。控制凸起底面112的尺寸L2与相邻两个凸起11之间的距离d5有利于提升颜色渐变的流畅度，使颜色变化更加细腻。
请再次参阅图8，本申请一些实施方式中，凸起11的顶点111相对凸起底面112的高度h为0.1μm～20μm，凸起11的顶点111相对凸起底面112的高度h具体可以但不限于为0.1μm～20μm。本申请一些实施方式中，凸起底面112的尺寸与凸起11的顶点111相对凸起底面112的高度h的比值大于或等于2。凸起底面112的尺寸与凸起11的顶点111相对凸起底面112的高度h的比值具体可以但不限于为2、4、6、8、10或15。控制凸起底面112的尺寸与凸起11的顶点111相对凸起底面112的高度h可以使颜色变化效果更为显著。
本申请一些实施方式中，凸起底面为多边形，在至少一个阵列方向上，多个凸起底面具有相对阵列方向渐变的相对旋转角度。请参阅图17，图17为本申请一实施例提供的纹理层的结构示意图，图17中，凸起底面为四边形，在第一阵列方向上，多个凸起底面在相对第一阵列的方向上发生旋转，且旋转角度逐渐增大。请参阅图18，图18为本申请一实施例提供的纹理层的结构示意图，图18中，凸起底面为五边形，在第一阵列方向上，多个凸起底面在相对第一阵列的方向上发生旋转，且旋转角度逐渐增大。请参阅图19，图19为本申请一实施例提供的纹理层的结构示意图，图19中，凸起底面为六边形，在第一阵列方向上，多个凸起底面在相对第一阵列的方向上发生旋转，且旋转角度逐渐增大。

本申请一些实施方式中，装饰基板还包括修饰层，修饰层包括显色层、磨砂层和闪光层中的一种或多种。本申请实施方式中，显色层可以是镀膜层，也可以是油墨层，只要具有一定颜色即可。本申请中，装饰膜片中的纹理层自身即具有一定的颜色效果，设置显色层可以进一步提高丰富颜色变化，该显色层与纹理层的结合可以实现单一颜色镀膜的颜色变化。磨砂层具有一定的防滑功能，并且视觉效果更加柔和，可以丰富产品的外观。闪光层指的是能够呈现闪点效果的修饰层，一些实施例中，闪光层包括掺杂有闪光颗粒的涂层，设置闪光层可以使装饰基板具有一定的炫彩效果。在一些实施例中，修饰层设置在纹理层的表面。在一些实施例中，修饰层设置在基材的表面。在一些实施例中，修饰层设置在基材和纹理层的表面。
本申请提供的装饰基板中，纹理层具有连续变化的特征结构，该结构可以实现装饰基板在不同角度下的颜色变化，例如在正面观察为浅紫到浅黄的渐变，在侧面观察为浅紫到浅蓝的渐变，呈现出动态立体的颜色渐变效果，从而大大提升产品的美观性。
本申请还提供了该装饰基板的制备方法，本申请实施方式中，纹理层的制备方法包括刻蚀、UV转印和热压成型中的一种或多种。在一些实施例中，基材包括透明膜片，例如基材可以是聚酯基片(PET膜)、聚碳酸酯基片(PC膜)、聚甲基丙烯酸甲酯基片(PMMA膜)，装饰基板的制备方法包括：根据纹理层的图案在模具上制作出具有纹理图案的纹理母版，将纹理母版转印基材表面，得到装饰基板，所得的装饰基板为纹理膜片。在一些实施例中，基材包括塑胶板材，装饰基板的制备方法包括：将纹理母版转印至基材表面，经热压成型得到装饰基板，所得的装饰基板为带纹理的塑胶板材。在一些实施例中，基材包括玻璃，装饰基板的制备方法包括：根据纹理层的图案在基材表面制备掩膜板，对基材进行刻蚀，掩膜板较薄处刻蚀作用较强，掩膜板较厚处刻蚀作用较弱，从而在基材表面形成纹理图案，得到装饰基板，所得的装饰基板为带纹理的玻璃。本申请提供的装饰基板的制备方法技术成熟、流程简单，生产的产品稳定性高，从而可以提高产品的良品率，适用于批量生产。
