具体实施方式
下面将结合本公开中的附图，对本公开中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
发明人已经发现，在相关技术中，如图1a所示，显示装置包括层叠设置的盖板1和显示面板2，显示面板2包括显示区21(即AA区)，在显示区21周边设置有周边区22，周边区22内通常设置黑矩阵，保证电路走线及封闭液晶等需要。盖板1包括透光区11(即VA区)和位于透光区11周边的非透光区12，非透光区12通常涂覆油墨进行遮挡。
为了避免盖板1的透光区11遮盖住显示面板2显示区21内的像素，通常将透光区11的尺寸设置为大于显示区21的尺寸。但是，这样设置后，如图1b所示，透过盖板1的透光区11会看到下方的显示区21周边的黑矩阵，即在显示面板2的显示区21周边显示黑边，影响视觉效果。
本公开提供一种消除显示装置的黑边的方法，如图2-6所示，所述显示装置包括层叠设置的盖板1和显示面板2，盖板1包括透光区11和位于透光区11周边的非透光区12，显示面板2包括显示区21，显示区21与透光区11相对应以便可以从透光区11观看显示区21，(即透光区11在所述显示面板2上的正投影落入到所述显示区21中)。作为示例，显示区21的尺寸大于透光区11的尺寸。显示区21的尺寸大于透光区11的尺寸可以理解为显示区21的总面积大于透光区11的总面积，例如，当显示区21为矩形时，显示区21的长边比透光区11的相应的一侧长，显示区21的短边比透光区11的相应的一侧长；也可以理解为，显示区21覆盖的区域包含透光区11覆盖的区域，或者，在如图2所示的视图中，显示区21在水平面上的正投影包含透光区11在水平面上的正投影。如图6所示，图6为图7中沿A-A’的截面图，显示区21包括第一子显示区211和位于第一子显示区211周边的第二子 显下区212。
所述消除显示装置的黑边的方法包括以下步骤：
使得第二子显示区212至少一侧的像素显示与非透光区12相同的颜色。具体的，如图6所示，所述像素中远离边缘位置的像素在盖板1上的正投影位于透光区11的范围之内。也就是说，采用本公开的消除显示装置的黑边的方法对所述显示装置进行处理后，显示面板2中有效的显示区21的尺寸小于盖板1的透光区11的尺寸。
盖板1的非透光区12内通常涂覆有油墨，第二子显示区212至少一侧的像素显示的颜色与油墨的颜色相同。
本公开提供的消除显示装置的黑边的方法，将显示面板2的显示区21的尺寸大于盖板1的透光区11的尺寸，其中，显示区21包括位于显示面板2中间位置的第一子显示区211和位于第一子显示区211周边的第二子显示区212，使得第二子显示区212的至少一侧的像素显示与盖板1的非透光区12相同的颜色，以使第一子显示区211的尺寸小于透光区11的尺寸，通过利用显示区21边界处的像素(即第二子显示区212的像素)遮挡位于周边区22和第一子显示区211之间的黑矩阵，从而消除显示装置的黑边，提高显示效果。
在一个实施例中，在将第二子显示区212的至少一侧的像素显示与非透光区12相同的颜色之前，根据本公开的一个实施例的消除显示装置的黑边的方法还包括以下步骤：
检测第二子显示区212中与透光区11的边界对应的像素位置，其中，透光区11的边界为与所述像素对应的边界。
如图7所示，显示面板2呈矩形，第二子显示区212呈回字型，在第一方向(即x轴方向)和第二方向(即y轴方向)上分别包括两侧。
以下结合图3至图6，以消除第一方向上的黑边为例，对本公开提供的消除显示装置的黑边的方法进行详细说明。
如图3所示，所述检测第二子显示区212中与透光区11的边 界对应的像素位置的步骤，具体包括：
检测第二子显示区212中与透光区11的第一边界111所对应的第一像素位置i和第二子显示区212中与透光区11的第二边界112所对应的第二像素位置j。其中，第二边界112与第一边界111相对设置，第一边界111到第二边界112的方向为第一方向。在本公开中，第一边界111为透光区11的左侧边界，第二边界112为透光区11的右侧边界。
具体的，结合图4a和图4b所示，从显示区21的与第一边界111一侧沿第一方向逐列显示扫描测试线3。扫描测试线3可以通过向显示面板2的数据线加载测试信号被点亮，扫描测试线3的宽度即为像素的宽度。在扫描过程中，记录在透光区11观测到扫描测试线3开始出现时对应的第一像素位置i和在透光区11观测到扫描测试线3消失时对应的第二像素位置j。
由于显示区21的尺寸大于透光区11的尺寸，在从显示区21的左侧逐列显示扫描测试线3时，在显示区21的左侧边缘区域内，由于有非透光区12的遮挡，扫描测试线3虽然被点亮但是无法显示。一旦位于第一边界111右侧的扫描测试线3被点亮，此时点亮的扫描测试线3位于透光区11的范围内，即可以显示扫描测试线3。也就是说，在显示区21的与第一边界111和第二边界112之间区域(即透光区11)对应的范围内，均可以显示扫描测试线3，一旦位于第二边界112右侧的扫描测试线3点亮，显示区21的该范围内的扫描测试线3消失。
在显示扫描测试线3的过程中，记录在透光区11观测到扫描测试线3开始出现时对应的第一像素位置i和在透光区11观测到扫描测试线3消失时对应的第二像素位置j。第一像素位置i即为透光区11的第一边界111所对应的像素位置，第二像素位置j即为透光区11的第二边界112所对应的像素位置。
在本公开中，像素位置是指显示面板2中像素的列数，例如，第一像素位置i可以表示为显示面板2的第100列像素，第二像素位置j可以表示为显示面板2的第1000列像素。
所述将第二子显示区212的至少一个边界位置的像素显示与非透光区12中油墨相同的颜色的步骤，具体包括以下步骤：
步骤111，根据第一像素位置i、第二像素位置j以及第一子显示区211在第一方向上的分辨率，确定第二子显示区212在第一像素位置i一侧和/或第二像素位置j一侧的待处理像素的列数。
具体的，如图2、3所示，透光区11位于显示区21的中间位置。如图5所示，第二子显示区212在第一像素位置i一侧的待处理像素的列数为L1+C，第二子显示区212在第二像素位置j一侧的待处理像素的列数为L2+C。
后续结合图4a-4b和图5，对步骤111的具体实现方式进行详细说明。
步骤112，使得第二子显示区212在第一像素位置i一侧的待处理像素和/或第二子显示区在第二像素位置j一侧的待处理像素，显示与非透光区12颜色相同的颜色。
具体的，如图6所示，将第二子显示区212在第一像素位置i一侧的(L1+C)列待处理像素显示与非透光区12中油墨颜色相同的颜色；和/或，将第二子显示区212在第二像素位置j一侧的(L2+C)列待处理像素显示与非透光区12中油墨颜色相同的颜色。这样，从所述显示装置的外侧(即盖板1远离显示面板2的一侧)观看时，从视觉上相当于将非透光区12从边界向中间延伸了一段距离，从而达到遮挡住显示面板2的周边区22内黑矩阵的效果。
需要说明的是，由于第二子显示区212在第一像素位置i一侧的第一待处理像素，以及第二子显示区212在第二像素位置j一侧的第一待处理像素已被非透光区12遮挡，因此，第二子显示区212在第一像素位置i一侧位于透光区内的待处理像素的列数和第二子显示区212在第二像素位置j一侧位于透光区内的待处理像素的列数均可以为C。也就是说，可以仅将第二子显示区212在第一像素位置i一侧位于透光区内的C列第二待处理像素，和/或第二子显示区212在第二像素位置j一侧位于透光区内的C列第 二待处理像素显示和非透光区颜色相同的颜色。
结合图4a和图5所示，所述根据第一像素位置i、第二像素位置j以及第一子显示区211在第一方向上的分辨率，确定第二子显示区2112在第一像素位置i一侧和/或第二像素位置j一侧的待处理像素的列数(即步骤111)包括以下步骤：
步骤1111，根据第一像素位置i和第二像素位置j，分别计算第二子显示区212在第一像素位置i的一侧被非透光区12遮挡的第一待处理像素的列数L1，和/或第二子显示区212在第二像素位置j的一侧被非透光区12遮挡的第一待处理像素的列数L2，以及，显示区21在透光区11内的在第一方向上对应的像素的列数m。
具体的，如图4a所示，若第二子显示区212内与透光区11的第一边界111对应的第一像素位置为第i列像素，第二子显示区212内与透光区11的第二边界112对应的第二像素位置j为第j列像素，显示区21在第一方向上的像素的总列数为n，则第二子显示区212在第一像素位置i一侧被非透光区12覆盖的第一待处理像素的列数L1＝i，第二子显示区212在第二像素位置j一侧被非透光区12覆盖的第一待处理像素的列数L2＝n-j+1，透光区11在第一方向上对应的像素的列数m＝j-i-1。
步骤1112，根据透光区11在第一方向上对应的像素的列数m和第一子显示区211在第一方向上的分辨率，计算第二待处理像素的列数C。
具体的，如图4a所示，由于透光区11位于显示区21的中间位置，因此在第二子显示区212的第一像素位置i一侧的第二待处理像素的宽度与第二子显示区212在第二像素位置j一侧的第二待处理像素的宽度相等，均为C。
具体的，可以根据以下公式(1)计算第二待处理像素的列数C：
C＝(m-h)/2；      (1)
其中，m为透光区11在第一方向上对应的像素的列数，h为第一子显示区211在第一方向上的分辨率。第一子显示区211的 分辨率为h*v，h为第一子显示区211在第一方向(即横向方向)上的像素的列数，v为第一子显示区211在第二方向(即纵向方向)上的像素的行数。通常，对于全高清(Full High Definition，FHD)的显示面板而言，其分辨率通常为1080*1920，即在第一方向上共有1080列像素，这里所说的像素是指R、G、B、W等。需要说明的是，显示面板2也可以为高清(High Definition，HD)面板、宽屏高清(2K分辨率，WQHD)面板、QFHD(4K分辨率，Quad Full High Definition)面板等。
步骤1113，根据第二子显示区212在第一像素位置i一侧的第一待处理像素的列数L1和第二待处理像素的列数C，计算第二子显示区212在第一像素位置i一侧的待处理像素的列数P1，和/或，根据第二子显示区212在第二像素位置j一侧的第一待处理像素的列数L2和第二待处理像素的列数C，计算第二子显示区212在第二像素位置j一侧的待处理像素的列数P2。
具体的，如图5所示，可以根据以下公式(2)计算第二子显示区212在第一像素位置i一侧的待处理像素的列数：
P1＝L1+C；             (2)
其中，P1为第二子显示区212在第一像素位置i一侧的待处理像素的列数，L1为第二子显示区212在第一像素位置i一侧的第一待处理像素的列数，C为第二待处理像素的列数。
可以根据以下公式(3)计算第二子显示区212在第二像素位置j一侧的待处理像素的列数：
P2＝L2+C；              (3)
其中，P2为第二子显示区212在第二像素位置j一侧的待处理像素的列数，L2为第二子显示区212在第二像素位置j一侧的第一待处理像素的列数，C为第二待处理像素的列数。
需要说明的是，不但可以在第一方向上消除显示装置的黑边，进一步还可以在第二方向上消除显示装置的黑边，即消除显示装置四周的黑边，从而可以进一步提高消除显示装置的黑边的效果。
因此，所述检测第二子显示区212中与透光区11的边界对应 的像素位置的步骤，还包括以下步骤：
检测第二子显示区212中与透光区11的第三边界所对应的第三像素位置和所述第二子显示区212中与透光区11的第四边界所对应的第四像素位置，第四边界与第三边界相对设置，第三边界到第四边界的方向为第二方向，第二方向与第一方向垂直。
在本公开实施例中，第三边界为透光区11的上侧边界，第四边界为透光区11的下侧边界。
需要说明的是，检测第三像素位置和第四像素位置的过程与检测第一像素位置i和第二像素位置j的过程相同，在此不再赘述。
相应的，在检测出第三像素位置和第四像素位置之后，所述使得第二子显示区212的至少一侧的像素显示与非透光区12相同的颜色的步骤，还包括以下步骤：
步骤111’，根据第三像素位置、第四像素位置以及第一子显示区211在第二方向上的分辨率，确定第二子显示区212在第三像素位置一侧和/或第四像素位置一侧的待处理像素的列数。
需要说明的是，确定第二子显示区212在第三像素位置一侧和/或第四像素位置一侧的待处理像素的列数的实现过程，与确定第二子显示区212在第一像素位置i一侧和/或第二像素位置j一侧的待处理像素的列数的实现过程相同，不再赘述。
步骤112’，使得第二子显示区212在第三像素位置一侧的待处理像素和/或所述第二子显示区在所述第四像素位置一侧的待处理像素，显示与非透光区12颜色相同的颜色。
本公开还提供一种显示装置，如图6所示，所述显示装置包括层叠设置的盖板1和显示面板2，盖板1包括透光区11和位于透光区11周边的非透光区12，显示面板2包括与透光区11对应的显示区21，优选地，显示区21的尺寸大于透光区11的尺寸，然而，显示区21的尺寸可以等于透光区11的尺寸；并且，显示区21包括第一子显示区211和位于第一子显示区211周边的第二子显示区212，第二子显示区212至少一侧的像素用于显示与非透光区12相同的颜色。
