 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。在图中，结构相近的单元是用以相同标号表示。
本申请实施例提供一种显示装置和终端，用以缓解现有显示装置中相邻行子像素间的边界不清晰的技术问题。
本申请提供一种显示装置，包括多个子像素、多条扫描线、多条数据线和驱动芯片；多个子像素在显示区内呈阵列排布；扫描线沿水平方向延伸，各扫描线沿竖直方向间隔设置，每条扫描线连接一行子像素，在工作阶段，多条扫描线逐行输入扫描信号，控制多个子像素逐行打开；数据线与扫描线垂直，各数据线沿水平方向间隔设置，每条数据线连接一列子像素，在工作阶段，多条数据线输入数据信号，控制打开的子像素在各数据信号对应的灰阶下逐行显示；驱动芯片用于存储第一区域内第i+1行子像素的待输入数据信号对应的第一灰阶，第一区域与扫描线的扫描信号输入端的距离大于阈值，第一区域内包括至少一列子像素，并用于在获取第一区域内第i行子像素输入的第一数据信号对应的第二灰阶与第一灰阶的第一灰阶差值后，根据第一灰阶差值，在第i+1行子像素打开之前，控制第一区域内子像素对应的第一数据线向第i行子像素输入补偿后的第二数据信号。
如图1所示，本申请的显示装置中，多个子像素10在显示区内呈阵列排布，形成多行和多列，G1、G2、...、Gi、Gi+1、...、Gn表示沿竖直方向自上而下间隔设置的第1条、第2条、...、第i条、第i+1条至第n条扫描线，i、n均为正整数且i＜n，扫描线沿水平方向延伸，D1、D2、...、Dj、Dj+1、...、Dm表示沿水平方向自左向右间隔设置的第1条、第2条、...、第j条、第j+1条至第m条数据线，j、m均为正整数且j＜m，数据线与扫描线垂直，即沿竖直方向延伸。每条扫描线均连接一行子像素10，该行中每个子像素10均包括像素驱动电路，在显示装置进入的工作阶段后，扫描线的输出信号端向像素驱动电路输入扫描信号Gate，将对应行的m个子像素10打开，m条数据线向该行的每个子像素10的像素驱动电路中输入数据信号Data，使各子像素10在各数据信号Data对应的灰阶下进行显示。
如图2所示，同一条扫描线中由左侧输入的扫描信号Gate，用于打开一整行的子像素10，然而，在大尺寸的显示面板中，扫描信号Gate由最左侧输到最右侧距离较远，会出现电阻/电容延迟 (RC Delay)，使得矩形的波形发生改变。
当某一行子像素写入数据信号结束后，数据线要向下一行子像素写入数据信号，而当前行子像素对应的扫描线中，扫描信号不能立刻达到关闭电位，而是需要一段时间才能达到，因此在下一行子像素写入数据时，当前行子像素仍然处于开启状态，因此原本要写入下一行子像素的数据信号会有一部分写入到当前行子像素中，即出现错充。
如图3所示，在现有的液晶显示面板中，当某一行子像素写入的数据信号为负极性时，用Data R-表示，则下一行子像素写入的数据信号为正极性，由于扫描信号的RC延迟，因此原本要写入下一行子像素的正极性数据信号会有一部分写入到当前行子像素中，使得当前行子像素的电位Pixel R-偏高；当某一行子像素写入的数据信号为正极性时，用Data R+表示，则下一行子像素写入的数据信号为负极性，由于扫描信号的RC延迟，因此原本要写入下一行子像素的负极性数据信号会有一部分写入到当前行子像素中，使得当前行子像素的电位Pixel R+偏低。
如图4所示，从现有显示面板中取9行子像素，每行子像素均包括红色子像素R、绿色子像素G和蓝色子像素B，将第1至3行子像素中的绿色子像素G和蓝色子像素B关闭，仅打开红色子像素R，则该3行子像素显示红色，将第4至6行子像素中的红色子像素R和蓝色子像素B关闭，仅打开绿色子像素G，则该3行子像素显示绿色，将第7至9行子像素中的红色子像素R和绿色子像素G关闭，仅打开蓝色子像素B，则该3行子像素显示蓝色。此时，显示面板中呈现红色、绿色和蓝色三条色带，如图4中的a所示。
为方便表述，取前6行子像素进行说明，如图4中的b所示。对于第1列的红色子像素R，自上而下第3行红色子像素R为打开状态，第4行红色子像素R为关闭状态，即第4行红色子像素R的灰阶是减小状态，此时，对于第4行红色子像素R，数据线输入的数据信号为负极性，而在扫描线的扫描信号出现RC延迟时，原本要输入到第4行红色子像素R中的负极性数据信号会错充到第3行红色子像素R中，使得第3行红色子像素R的亮度偏暗。
对于第二列的绿色子像素G，自上而下第3行绿色子像素G为关闭状态，第4行绿色子像素G为打开状态，此时，对于第4行绿色子像素G，由于扫描线的扫描信号出现RC延迟时，扫描信号不能立刻达到开启电位，而是需要一段时间才能达到，使得第4行绿色子像素G的充电时间过短，充电不足，亮度也会偏暗。
由于充电不足和错充的同时影响，在第3行子像素与第4行子像素所在区域11内，两行子像素边界不清晰，会出现黑线，影响显示效果。现有技术对于充电不足已有相应的补偿方法，本申请的补偿方式主要针对错充问题进行补偿。
如图1所示，在本申请实施例提供的显示装置中，多个子像素10在显示区内阵列排布，其中至少一列子像素位于第一区域100中，其中第一区域100与扫描线的扫描信号输入端的距离大于阈值，即在第一区域100内的子像素距离扫描信号输入端较远，扫描信号会发生RC延迟，因此可以对该区域内的子像素进行补偿。针对不同的机种和尺寸，阈值也会不同。对应向第一区域100内的子像素输入数据信号的各数据线为第一数据线。
在一种实施例中，第一区域100与显示区大小相等，即对于显示装置中所有子像素均进行补偿。
在一种实施例中，扫描信号输入端设置在显示装置的左侧或右侧，第一区域100位于显示区内远离扫描信号输入端的一侧。此时，显示装置采用单侧扫描方式，当扫描信号输入端在显示装置左侧时，第一区域100位于显示区内的右侧，且与扫描信号输入端的距离大于阈值，当扫描信号输入端在显示装置右侧时，第一区域100位于显示区内的左侧，且与扫描信号输入端的距离大于阈值。
在一种实施例中，扫描信号输入端设置在显示装置的左侧和右侧，第一区域位于显示区内的中间区域。此时，显示装置采用双侧扫描的方式，第一区域100位于显示区内的中间区域，且与左侧和右侧的扫描信号输入端的距离均大于阈值。
在本申请中，在显示装置进入工作阶段后，驱动芯片用于存储第一区域100内第i+1行子像素的待输入数据信号对应的第一灰阶，即第i+1行子像素在输入数据信号之前，先将该数据信号对应的第一灰阶存储起来，然后获取第一区域100内第i行子像素输入的第一数据信号对应的第二灰阶与第一灰阶的第一灰阶差值，并根据第一灰阶差值，在第i+1行子像素打开之前，控制第一区域100内子像素对应的第一数据线向第i行子像素输入补偿后的第二数据信号。
在第一区域100内，扫描信号会出现RC延迟，第i+1行的数据信号会错充到第i行的子像素中，本申请在第一区域100内的第i+1行子像素打开之前，根据驱动芯片获取到的第一灰阶差值，先对第一区域100内的第i行子像素进行数据补偿，使得第i行子像素的错充数据信号被抵消，然后再输入第i+1行子像素的数据信号，从而缓解了错充现象，使得相邻行子像素的边界清晰，提高了显示效果。
在一种实施例中，驱动芯片用于，在第一灰阶差值为正值时，控制第一数据线向第i行子像素输入补偿后的第二数据信号，第二数据信号对应的第三灰阶大于第二灰阶。
如图5所示，第i+1行子像素中待输入的数据信号对应的灰阶为第一灰阶，第i行子像素输入的第一数据信号对应的灰阶为第二灰阶，驱动芯片获取第二灰阶与第一灰阶的第一灰阶差值，当第一灰阶差值为正值时，表明第一区域100中第i行子像素的数据信号为正极性，用Data R+表示，第i+1行子像素的数据信号为负极性，第i+1行子像素的负极性数据信号会被错充到第i行子像素中时，使得第i行子像素亮度偏暗，此时，驱动芯片控制第一数据线向第i行子像素输入补偿后的第二数据信号，且第二数据信号对应的第三灰阶大于第二灰阶，即对第i行子像素进行过充处理，使得第i行子像素的电位Pixel R+被调高，第二数据与第一数据的差值会将错充到第i行子像素中的负极性数据信号抵消掉，从而可以将第i行子像素亮度调节至正常水平。
在一种实施例中，驱动芯片用于，在第一灰阶差值为负值时，控制第一数据线向第i行子像素输入补偿后的第二数据信号，第二数据信号对应的第三灰阶小于第二灰阶。
如图5所示，驱动芯片获取第二灰阶与第一灰阶的第一灰阶差值，当第一灰阶差值为负值时，表明第一区域100中第i行子像素的数据信号为负极性，用Data R-表示，第i+1行子像素的数据信号为正极性，第i+1行子像素的正极性数据信号会被错充到第i行子像素中时，使得第i行子像素亮度偏亮，此时，驱动芯片控制第一数据线向第i行子像素输入补偿后的第二数据信号，且第二数据信号对应的第三灰阶小于第二灰阶，使得第i行子像素的电位Pixel R-被调低，第二数据与第一数据的差值会将错充到第i行子像素中的正极性数据信号抵消掉，从而可以将第i行子像素亮度调节至正常水平。
如图6所示，当采用和图4中相同的点亮方式时，显示装置中也呈现红色、绿色和蓝色三条色带，如图6中的a所示。为方便表述，同样取前6行子像素进行说明，如图6中的b所示。对于绿色子像素G的充电不足补偿采用现有的补偿方式，对于红色子像素R的错充现象，在第4行红色子像素R的待输入数据信号输入之前，先将待输入数据信号对应的第一灰阶存储在驱动芯片中，然后驱动芯片获取第3行红色子像素R的第一数据信号对应的第二灰阶与第一灰阶的第一灰阶差值，由于第3行红色子像素R为打开状态，第4行红色子像素R为关闭状态，即第4行红色子像素R的灰阶是减小状态，因此第一灰阶差值为正值，驱动芯片控制第一数据线向第3行子像素输入补偿后的第二数据信号，第二数据信号对应的第三灰阶大于第二灰阶，使得第3行红色子像素R的亮度提高，从而使得第3行子像素与第4行子像素所在区域11内，两行子像素的边界清晰，不会出现黑线，提高了显示效果。
由上述实施例可知，驱动芯片在获取到第一灰阶差值后，根据第一灰阶差值的正负，控制第一数据线向第i行子像素输入第三数据信号，以对第i行子像素的错充进行补偿，使其亮度处于正常水平。驱动芯片在控制第一数据线输入第三数据信号时，可通过不同方式得到第三数据信号的具体数值。
在一种实施例中，驱动芯片用于，在获取第一灰阶差值后，查询补偿表得到第一灰阶差值对应的目标灰阶，并控制第一数据线将目标灰阶对应的数据信号作为第二数据信号，向第i行子像素输入。
如图7所示，Line i+1表示第i+1行子像素，Line i表示第i行子像素，以第i+1行子像素的待输入数据信号对应的第一灰阶为0，第i行子像素的第一数据信号对应的第二灰阶为128进行说明。第一区域100内第i+1行子像素的数据信号在输入之前，先将该数据信号对应的第一灰阶0存储在驱动芯片的缓存器Buffer中，然后，驱动芯片获取第一区域100内第i行子像素输入的第一数据信号对应的第二灰阶128与第一灰阶0的第一灰阶差值128，该第一灰阶差值128为正值，表明第i+1行子像素的灰阶相对于第i行是减小的，则驱动芯片在获取到第一灰阶差值128后，从补偿表中得到第一灰阶差值128对应的目标灰阶135，目标灰阶是指第i行子像素的亮度正常时的灰阶，补偿表为预先存储在驱动芯片中的错充补偿表，在查询到目标灰阶135后，再控制第一数据线将目标灰阶135对应的数据信号作为第二数据信号，向第i行子像素输入。
在一种实施例中，驱动芯片用于，在获取第一灰阶差值后，查询补偿表得到第一灰阶差值对应的第二灰阶差值，再将第一灰阶差值与第二灰阶差值叠加得到目标灰阶，然后控制第一数据线将目标灰阶对应的数据信号作为第二数据信号，向第i行子像素输入。此时，驱动芯片先获取第一区域100内第i行子像素输入的第一数据信号对应的第二灰阶128与第一灰阶0的第一灰阶差值128，该第一灰阶差值128为正值，表明第i+1行子像素的灰阶相对于第i行是减小的，则驱动芯片在获取到第一灰阶差值128后，从补偿表中得到第一灰阶差值128对应的第二灰阶差值7，其中第二灰阶差值7为第一灰阶差值与目标灰阶1之间的差值，然后，再将第一灰阶差值127与第二灰阶差值7进行叠加，得到目标灰阶135，再控制第一数据线将目标灰阶135对应的数据信号作为第二数据信号，向第i行子像素输入。
在一种实施例中，驱动芯片用于，在获取第一灰阶差值后，计算得到第二数据信号，然后控制第一数据线将向第i行子像素输入第二数据信号。此时，驱动芯片先获取第一区域100内第i行子像素输入的第一数据信号对应的第二灰阶128与第一灰阶0的第一灰阶差值128，然后直接计算得到当第一灰阶差值为128时需要输入的第二数据信号的数值，再控制第一数据线将目标灰阶135对应的数据信号作为第二数据信号，向第i行子像素输入。
通过上述实施例可知，本申请的显示装置，在第一区域内的第i+1行子像素打开之前，根据驱动芯片获取到的第一灰阶差值，先对第一区域内的第i行子像素进行数据补偿，然后再输入第i+1行子像素的数据信号，使得第i行子像素的补偿数据信号和错充数据信号相互抵消，从而缓解了错充现象，使得相邻行子像素的边界清晰，提高了显示效果。
本申请还提供一种终端，包括显示装置和外壳，其中显示装置为上述任一实施例所述的显示装置。
根据以上实施例可知：
本申请提供一种显示装置和终端，显示装置包括多个子像素、多条扫描线、多条数据线、驱动芯片；多个子像素在显示区内呈阵列排布；扫描线沿水平方向延伸，各扫描线沿竖直方向间隔设置，每条扫描线连接一行子像素，在工作阶段，多条扫描线逐行输入扫描信号，控制多个子像素逐行打开；数据线与扫描线垂直，各数据线沿水平方向间隔设置，每条数据线连接一列子像素，在工作阶段，多条数据线输入数据信号，控制打开的子像素在各数据信号对应的灰阶下逐行显示；驱动芯片用于存储第一区域内第i+1行子像素的待输入数据信号对应的第一灰阶，第一区域与扫描线的扫描信号输入端的距离大于阈值，第一区域内包括至少一列子像素，并用于获取第一区域内第i行子像素输入的第一数据信号对应的第二灰阶与所述第一灰阶的第一灰阶差值，并根据第一灰阶差值，在第i+1行子像素打开之前，控制第一区域内子像素对应的第一数据线向第i行子像素输入补偿后的第二数据信号。本申请在第一区域内的第i+1行子像素打开之前，根据驱动芯片获取到的第一灰阶差值，先对第一区域内的第i行子像素进行数据补偿，然后再输入第i+1行子像素的数据信号，使得第i行子像素的补偿数据信号和错充数据信号相互抵消，从而缓解了错充现象，使得相邻行子像素的边界清晰，提高了显示效果。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例所提供的一种显示装置和终端进行了详细介绍，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技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
