具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
本发明一实施例提供了一种边界判定方法，可用于3D显示装置中，如图1所示，该方法可以包括：
步骤S11，分别将待显示第一视图和第二视图划分为多个理论像素单元，并确定每一个理论像素单元的各个颜色分量。
具体的，显示装置中的一个像素对应于一个理论像素单元。在步骤S11中，可以根据第一视图按照3D显示装置的理论上能够达到的像素的个数划分为多个理论像素单元。之后确定各个理论像素单元中的红、绿、蓝所占的颜色分量。并按照相同的方式，得到第二视图对应的多个理论像素单元以及各个理论像素单元中红、绿、蓝所占的颜色分量。
步骤S12，针对用于显示每一个视图的每一个亚像素，根据该亚像素对应的预设采样区所覆盖的、属于该视图的各个理论像素单元中 该亚像素的颜色对应的颜色分量确定该亚像素的发光亮度。
具体的，这里的步骤S12可以具体是指：针对每一个亚像素，确定其对应的矩形采样区与所述多个理论像素单元中的每一个理论像素单元的重叠面积以及在该理论像素单元中该亚像素的颜色对应的颜色分量；确定每一个理论像素单元对应的重叠面积与对应的颜色分量的乘积；根据各个乘积的和以及采样区的面积确定该亚像素的发光亮度。当然在实际应用中，在使用矩形采样区进行采样之后，也可以通过其他方式确定对应亚像素的发光强度。本发明实施例中不再进行详细说明。
步骤S13，针对每一个视图，根据每一种颜色的相邻两个亚像素之间的亮度差确定在该视图中该颜色的亚像素的边界。
本发明的实施例提供的边界判定方法，能够准确确定3D显示装置中的边界。
根据本发明的实施例，上述的步骤S13可以具体包括：
对于用于显示同一视图的同一种颜色的两个相邻亚像素，在第一亚像素对应的发光亮度为第二亚像素对应的发光亮度的1.5-2倍时，判定该颜色的亚像素的边界位于所述第一亚像素和所述第二亚像素之间。
在实际应用中，如果第一亚像素对应的发光亮度大于第二亚像素对应的发光亮度的2倍之上，一般的边界较为清晰，此时无需执行后续的亮度调整过程。而如果第一亚像素对应的发光亮度为第二亚像素对应的发光亮度的1-1.5倍时，则说明两个亚像素之间很可能并不存在边界。本发明的实施例中，在第一亚像素对应的发光亮度为第二亚像素对应的发光亮度的1.5-2倍时，判定该颜色的亚像素的边界位于所述第一亚像素和所述第二亚像素之间。当不在此范围内时，判定该颜色的亚像素的边界没有位于所述第一亚像素和所述第二亚像素之间，这样也就避免了后续的亮度调整过程。
根据本发明的实施例，这里的第一亚像素对应的发光亮度为第二亚像素对应的发光亮度的1.7倍时，判定该颜色的亚像素的边界位于所述第一亚像素和所述第二亚像素之间。
另一方面，本发明的实施例还提供了一种显示驱动方法，如图2所示，所述方法包括：
步骤S21-S23同步骤S11-步骤S13；
步骤S24，根据第一预设策略提高位于边界两侧的两个该种颜色的相邻亚像素中亮度较大的亚像素的发光亮度和/或根据第二预设策略降低亮度较小的亚像素的发光亮度；
步骤S25，根据调整后的发光亮度进行显示。
通过本发明的实施例提供的显示驱动方法，能够增加一个视图的同一颜色的亚像素的边界两侧的两个亚像素之间的亮度差，从而使得边界更加清晰。
这里的第一预设策略可以是指按照一个预设的比例提高两个该种颜色的相邻亚像素中亮度较大的亚像素的发光亮度，或者按照一个预设的比例降低两个该种颜色的相邻亚像素中亮度较小的亚像素的发光亮度。比如将亮度较大的亚像素的发光亮度提高30％，或者将亮度较小的亚像素的发光亮度降低30％。
作为一种可选的方式，本发明实施例中，这里的步骤S24可以具体为：
根据第三预设策略扩大位于边界两侧的两个该种颜色的相邻亚像素中亮度较大的亚像素所对应的采样区域并相应缩小亮度较小的亚像素所对应的采样区域。例如，将亮度较大的亚像素所对应的采样区向亮度较小的亚像素的边界扩展至所确定的边界当前所在的理论像素单元朝向亮度较低的亚像素的边界。
通过这种方式，能够使得亮度较小的亚像素的采样区在边界处缩小，减少或者避免对边界处的理论像素单元进行采样，这样就降低了 亮度较小的亚像素的发光亮度。并且通过这种方式，能够使得所显示的边界更符合实际边界情况。
具体的，这里的第三预设策略可以是指可以将亮度较高的亚像素的采样区朝向亮度较低的亚像素的边界扩展至该边界当前所在的理论像素单元朝向亮度较低的亚像素的边界。
下面结合具体的像素阵列和光栅阵列对本发明实施例提供的边界判定方法及相应的显示驱动方法进行详细说明。该3D显示装置可以包括像素阵列和光栅阵列，如图3所示，为一种可能的包含8列(S1-S8)、24行(R1-R24)的亚像素的像素阵列的示意图，其中的奇数列S1、S3、S5、S7列用于显示右眼视图，偶数列S2、S4、S6、S8列用于显示左眼视图。在每一列中，蓝色亚像素、绿色亚像素和红色亚像素交替排列，为了便于区分，用于显示右眼视图的蓝色亚像素、绿色亚像素和红色亚像素分别表示为B1、G1、R1。用于显示左眼视图的蓝色亚像素、绿色亚像素和红色亚像素分别表示为B2、G2、R2。
图4为还示出了光栅阵列的分布示意图，该光栅阵列遮挡用于显示左眼视图的亚像素列的右侧，并遮挡用于显示右眼视图的亚像素列的左侧。这样，对于经用于显示左眼视图的亚像素列出射的光线只能向左传播被左眼看到，经用于显示右眼视图的亚像素列出射的光线只能向右传播被右眼看到，这样进行适当的控制，可以使左眼和右眼看到不同的图像，从而实现3D显示。
以下以判断右眼视图的红色边界的具体方式进行说明。如图5所示，对于S3列R12行的红色亚像素R1，首先根据其对应的预设采样区确定其发光亮度。参考图5，S3列R12行的红色亚像素R1对应的预设采样区可以如图中的虚线矩形框所示。由于右眼视图中的红色亚像素R1均匀分布，其对应的预设采样区的大小相同。预设采样区在列方向上的长度均为亚像素在列方向的长度的三倍，在行方向上的长 度均为在行方向上的长度的二倍。之后按照该预设采样区在右眼视图中所覆盖的各个理论像素单元的重叠面积以及红色在各个理论像素单元中的分量确定S3列R12行的红色亚像素R1的发光强度。
参考图6，对于S3列R9行的红色亚像素R1，其右侧相邻的红色亚像素R1在S5列R9行，其下方相邻的红色亚像素R1在S3列R12行。按照上述确定S3列R12行的红色亚像素R1的发光亮度的方式分别确定S5列R9行、S3列R12行的红色亚像素R1的发光亮度。确定S3列R9行的红色亚像素R1与S5列R9行的红色亚像素R1的亮度差是否为较小发光亮度的一个的0.5倍至1倍之间，如果判断为是，则确定两个红色亚像素之间存在边界。相应的，确定S3列R9行的红色亚像素R1与S3列R12行的红色亚像素之间是否存在边界。
至此，完成了针对S3列R9行的红色亚像素R1与下方和右侧相邻红色亚像素R1之间的边界的判定过程。
如图7所示，假设按照上述的边界判定方法判断S3列的红色亚像素R1与其右侧的S5列的红色亚像素R1之间存在边界，且S3列的红色亚像素R1具有较高的亮度。则根据本发明实施例提供的显示驱动方法，将S3列红色亚像素R1的采样区向S5列的方向扩大，相应缩小S5列红色亚像素R1的采样区，如图8所示，S3列红色亚像素R1的采样区的右侧边界由S4列的中线处向右移动至S4列与S5列的交界处。通过这种方式，能够使得S5列红色亚像素的采样区缩小，减少与红色分量较高的理论像素单元的重叠面积，从而降低了S5列红色亚像素的亮度。
本发明实施例提供的边界判定方法和显示驱动方法也可以用于对不规则的边界进行判定并进行亮度调整，如图9示，为判定的边界呈锯齿状的一种情形。假设边界的上方的红色亚像素R1的亮度较大，边界下方的红色亚像素R1的亮度较小，则调整后的采样区可以参考 图10，边界上方的红色亚像素R1对应的采样区相对于图9扩大，边界下方的红色亚像素R1对应的采样区相对于图9缩小。另外，本发明的实施例提供的边界判定方法同样可以用于亚像素按照其他方式排列(比如delta像素阵列、菱形像素阵列)的情况。
图11中还示出了S5列的红色亚像素R1的红色亚像素与S3列的红色亚像素R1位于边界两侧，且与S7列红色亚像素R1列的红色亚像素也位于边界两侧的情况。假设S5列的红色亚像素R1的亮度大于S3列的红色亚像素R1的发光亮度，且大于S7列的红色亚像素R1的发光亮度，则按照本发明实施例提供的显示驱动方法进行调整后，如图12所示，调整采样区之后S5列的红色亚像素R13列的红色亚像素的采样区向S3列方向和向S5方向均扩大。
对右眼视图中蓝色和绿色，确定边界以及显示驱动的过程可以与上述的确定红色边界以及调整红色亚像素的亮度的方式一致。相应的，对于左眼视图中的各个颜色，也可以按照上述的方法确定相应的边界并进行相应的显示驱动。
另一方面，本发明实施例还提供了一种边界判定装置，用于3D显示装置中，该装置可用于执行上述任一项所述的边界判定方法，该装置包括：
