具体实施方式
为了进一步说明本公开实施例提供的驱动芯片、显示面板的驱动方法、显示装置，下面结合说明书附图进行详细描述。
请参阅图1和图2，对于显示区域的边界包括圆弧11或异形结构12(例如，缺口)的显示器件1，由于像素的排列无法与圆弧11或异形结构12的边界完美匹配，因此导致位于圆弧11或异形结构12的边界处的像素排布不整齐，如图3所示，显示器件显示的画面会在对应圆弧或异形结构的边界出现较为明显的锯齿感。
目前，解决上述锯齿感的常规方法主要包括以下两种：
第一种方法，如图4所示，在圆弧或异形结构的边界用黑矩阵2遮挡像素，使像素在圆弧或异形结构的边界处的显示是与该边界相匹配的平滑形状，从而弱化显示器件在显示时产生的锯齿感。但是由于每个像素至少包括R/G/B三种亚像素，而在采用黑矩阵2对像素进行遮挡时，该像素所包括的各亚像素被遮挡的面积不同，导致在圆弧或异形结构的边界处出现显示彩边的问题。更详细地说，例如图4中的第四行，靠近圆弧或异形结构的边界处 的R亚像素3遮挡最多，蓝色(B)亚像素5遮挡最少，绿色(G)亚像素4的遮挡面积在红色(R)亚像素3的遮挡面积和B亚像素5的遮挡面积之间。这就使得当显示器件显示白色(W)画面时，因为边界处的R/G/B亚像素全开，造成G亚像素4和B亚像素5的显示亮度远高于R亚像素3的显示亮度，造成在白画面边角处的显示偏青色(C)，宏观上看即为彩边效果。
第二种方法，如图5所示，对接近圆弧或异形结构的边界处的像素进行轻微遮挡，使得该像素依然是完整的像素，只是透过率降低(例如：图5中的第一行像素和第二行像素，靠近边界处的像素的透过率依次例如为GL236、GL189、GL158)。当使得显示器件在进行白色画面的显示时，接近圆弧或异形结构的边界处的像素的亮度会逐步下降，从而弱化在对应圆弧或异形结构的边界出现较为明显的锯齿感。但是在实际产品中，通过黑矩阵(BM)对像素进行轻微遮挡来控制像素的透过率时，黑矩阵的形状和遮挡方式不同，人眼识别的感觉也不同，因此为了实现更好的人眼识别感觉，需要对用于遮挡的黑矩阵的形状和遮挡方式进行大量验证，这导致生产成本和时间成本的不必要浪费。
从上述两种方法可以看出，相关技术中，主要是通过设置黑矩阵来遮挡位于圆弧或异形结构的边界处的像素，来解决显示器件在圆弧或异形结构的边界出现较为明显的锯齿感问题，而这种解决方式还存在彩边显示、浪费生产成本和时间成本等一系列问题。基于上述问题的存在，本公开的发明人经研究发现，可通过显示器件中的驱动芯片控制降低位于圆弧或异形结构的边界处的像素的透过率，从而实现不用改变黑矩阵的分布，就能够随意调节像素的透过率，实现弱化在圆弧或异形结构的边界处出现锯齿感的效果。
本公开实施例提供了一种驱动芯片，应用于显示面板，如图6所示，显示面板包括位于显示区域的多个亚像素，显示区域具有非直线延伸的边界6，多个亚像素包括与非直线延伸的边界6的距离实质上小于预设阈值的第一亚像素7和除第一亚像素7之外的第二亚像素8；该驱动芯片100包括调整电路200和驱动电路300，其中，调整电路200用于在进入预设显示模式时，将至少部分第一亚像素7在原始画面数据中的第一灰阶值调整为第二灰阶值，第二灰阶值实质上小于对应第一亚像素7的第一灰阶值；驱动电路300用于 按照第二灰阶值驱动第一亚像素7进行显示。
具体地，上述显示区域的非直线延伸的边界6具体可以包括：与亚像素形状(例如，矩形形状)不匹配的圆弧状的边界或者其它异形结构的边界。这里所称的“不匹配”是指非直线延伸的边界与该边界所经过的多个亚像素的外轮廓不重合。
上述预设阈值可以根据实际情况进行定义。上述第一亚像素7可以是指与非直线延伸的边界6的绝对距离(绝对距离可以是第一亚像素7与非直线延伸的边界6之间的最短距离)实质上小于一预设阈值的亚像素；也可以根据预设阈值确定一与非直线延伸的边界6相邻的区域，该区域内的所有亚像素即为第一亚像素7；也可以根据预设阈值确定另一与非直线延伸的边界6相邻的区域，该区域内的各个亚像素与非直线延伸的边界6的各个绝对距离的平均值实质上小于一预设阈值，该区域内的各个亚像素即为第一亚像素7。当然，本领域技术人员还可以根据实际情况做出其他方式的上述预设阈值的定义，本公开实施例并不以上述三种具体示例为限。
上述原始画面数据即为显示面板在进行显示时由该显示面板的中央处理器(CPU)输入的原始显示画面所对应的数据。显示面板在基于该原始画面数据进行显示时，显示区域显示实际的显示效果，而非显示区域(即非直线延伸的边界之外的区域)显示黑色画面，由此导致在非直线延伸的边界处会产生锯齿感。
采用上述驱动芯片驱动显示面板进行显示时，具体驱动过程如下：
在预设显示模式时，驱动芯片中的调整电路将至少部分第一亚像素在原始画面数据中的第一灰阶值调整为第二灰阶值，该第二灰阶值实质上小于对应第一亚像素的第一灰阶值；驱动芯片中的驱动电路按照第二灰阶值驱动第一亚像素进行显示，使得第一亚像素的显示亮度低于其在原始画面数据中对应的显示亮度。同时，驱动芯片还根据第二亚像素在原始画面数据中对应的灰度值驱动第二亚像素进行显示，使得显示面板处于显示状态。
根据上述驱动芯片的具体结构和驱动过程可知，本公开实施例提供的驱动芯片中，调整电路能够将显示面板中的至少部分第一亚像素在原始画面数据中的第一灰阶值调整为第二灰阶值，且第二灰阶值实质上小于对应第一亚 像素的第一灰阶值；驱动电路能够按照第二灰阶值驱动第一亚像素进行显示，使得第一亚像素的实际显示亮度低于该第一亚像素在原始画面数据中对应的显示亮度。因此，在利用本公开实施例提供的驱动芯片驱动显示面板进行显示时，能够控制接近非直线延伸的边界处的第一亚像素具有较低的显示亮度，从而弱化用户对显示画面边缘的亮度变化的感知，改善边界区域在显示画面中所出现的锯齿感，更好的提高了画面的显示品质。
由此可见，在本公开的技术方案中不需要通过黑矩阵遮挡第一亚像素来控制其显示亮度，而是通过驱动芯片来相应地控制第一亚像素的显示亮度，因此在利用本公开实施例提供的驱动芯片驱动显示面板进行显示时，不用改变显示面板中黑矩阵的分布，就能够随意调节第一亚像素的透过率，并确认第一亚像素处于不同透过率时显示面板对应的显示效果。可见，在利用本公开实施例提供的驱动芯片驱动显示面板进行显示时，不仅弱化了在非直线延伸的边界处出现锯齿感，还避免了彩边显示、浪费生产成本和时间成本等一系列问题。
进一步地，可设置调整电路在预设显示模式时，将全部第一亚像素的灰阶值调整为第二灰阶值，第二灰阶值实质上小于对应第一亚像素的第一灰阶值。
具体地，设置调整电路将全部第一亚像素的灰阶值调整为第二灰阶值，并使第二灰阶值实质上小于对应第一亚像素的第一灰阶值，能够使得显示面板中非直线延伸的边界附近的全部第一亚像素均具有较低的显示亮度，从而进一步改善了显示面板在进行显示时，在非直线延伸的边界处出现的锯齿感，更好的提高了画面的显示品质，改善用户对画面的体验。
进一步地，上述实施例提供的驱动芯片还包括存储单元400，该存储单元400用于获取并存储第一亚像素的位置信息。调整电路200在进入预设显示模式时，查找并获取所存储的位置信息，并根据位置信息，确定第一亚像素，并将第一亚像素对应原始画面的第一灰阶电压调整为第二灰阶电压。
具体地，显示面板中包括的亚像素呈阵列排布，且呈阵列排布的亚像素中，哪些亚像素能够进行有效的显示(即位于显示区域内的亚像素)是在显示面板设计时就已经确定的。驱动芯片能够通过代码一次性将具体有哪些亚 像素参与显示，以及各亚像素的位置信息记录在存储单元中，使得显示面板在进行显示时，可根据存储单元中存储的信息实现显示功能，而不需要再次对参与显示的亚像素的位置进行计算，很好的节省了运算量。更详细地说，驱动芯片中包括的存储单元能够获取并存储第一亚像素(需要进行灰阶电压调整的亚像素)的位置信息，和第二亚像素(不需要进行灰阶电压调整，按照原始画面数据进行显示的亚像素)的位置信息。值得注意，上述存储单元可选为时钟存储器，但是本公开各个实施例并不以此为限。
调整电路在进入预设显示模式时，先在存储单元中查找并获取所存储的位置信息，并根据该位置信息，从显示面板包括的全部亚像素中确定出哪些是第一亚像素，然后再将确定出的第一亚像素对应原始画面的第一灰阶电压调整为第二灰阶电压，使得第一亚像素的实际显示亮度相对于原始画面数据中对应的显示亮度降低，从而改善该边界区域在显示画面中所出现的锯齿感。
进一步地，上述实施例提供的驱动芯片100还包括Gamma补偿电路500，该Gamma补偿电路500用于基于gamma值仅对第一亚像素的灰阶电压进行补偿；调整电路200存储有第一亚像素的gamma校正值，具体用于在进入预设显示模式时，查找并获取所存储的第一亚像素对应的gamma校正值，并根据gamma校正值对Gamma补偿电路的gamma值进行校正，使得Gamma补偿电路500基于校正后的gamma值将第一亚像素对应原始画面的第一灰阶电压补偿为第二灰阶电压。
具体地，上述实施例提供的驱动芯片100还包括Gamma电路600和Gamma补偿电路500，其中，Gamma电路600用于为第二亚像素提供灰阶电压，该灰阶电压为第二亚像素在原始画面数据中对应的灰阶电压。值得注意，每一个第二亚像素仅对应一个Gamma电路600即可，并由对应的Gamma电路600为其提供灰阶电压，这样驱动芯片中不需要增加与第二亚像素对应的Gamma补偿电路，更好的节省了驱动芯片的空间。
上述Gamma补偿电路500与Gamma电路600不是同一电路，该Gamma补偿电路500用于控制第一亚像素，能够基于gamma值对第一亚像素的灰阶电压进行补偿。更详细地说，调整电路200存储有第一亚像素的gamma校正值，调整电路200具体用于在进入预设显示模式时，查找并获取所存储的第 一亚像素对应的gamma校正值，并根据gamma校正值对Gamma补偿电路的gamma值进行校正，使得Gamma补偿电路500能够基于校正后的gamma值将第一亚像素对应原始画面的第一灰阶电压补偿为第二灰阶电压。
更详细地说，以图7中第一行像素为例，在第一行像素中，从第17列像素开始，像素进行有效显示。当显示第一行第17列像素时，若第一行第17列像素在原始画面数据(原始画面可选为白色的纯色画面)中对应的灰阶电压是4.5V，则在进入预设显示模式时，Gamma补偿电路基于校正后的gamma值，通过代码控制第一行第17列像素所包括的各亚像素的灰阶电压，使得该第一行第17列像素的灰阶电压实质上小于4.5V，从而改善显示画面在非直线延伸的边界处出现的锯齿感。
值得注意，上述调整电路200中存储的第一亚像素的gamma校正值例如可以事先通过实验得到。具体地，可先调节显示面板中包括的各第一亚像素处于任意透过率，并确认显示面板中包括的全部第一亚像素在搭配不同透过率时，显示面板的显示效果，在确认显示面板中第一亚像素在不同透过率的搭配下，对应的显示效果后，选取其中一种搭配来确定第一亚像素的gamma校正值，在后续显示面板的生产中，可基于此gamma校正值进行量产。
为了更清楚的说明上述实施例提供的驱动芯片的工作过程，下面给出一具体实施例。
如图8所示，驱动芯片中的存储单元(例如，时钟存储器)事先存储显示面板中第一亚像素和第二亚像素对应的位置信息(步骤S801)；驱动芯片在驱动显示面板进行显示时，驱动芯片中的调整电路在存储单元中进行查找，以获得显示面板中各亚像素对应的位置信息，并根据位置信息，确定出第一亚像素和第二亚像素(步骤S802)；对于第一亚像素，Gamma补偿电路基于gamma值对第一亚像素的灰阶电压进行补偿，将第一亚像素对应原始画面的第一灰阶电压补偿为第二灰阶电压，驱动芯片中的驱动电路按照第二灰阶值驱动第一亚像素进行显示(步骤S803)；对于第二亚像素，Gamma电路为第二亚像素提供灰阶电压，该灰阶电压为第二亚像素在原始画面数据中对应的灰阶电压，驱动芯片中的驱动电路按照该灰阶电压驱动第二亚像素进行显示(步骤S804)。
本公开实施例还提供了一种显示面板的驱动方法，该显示面板中包括上述实施例提供的驱动芯片，该显示面板包括位于显示区域的多个亚像素，显示区域具有非直线延伸的边界，多个亚像素包括与非直线延伸的边界的距离实质上小于预设阈值的第一亚像素和除第一亚像素之外的第二亚像素；该驱动方法包括：
在进入预设显示模式时，将至少部分第一亚像素在原始画面数据中的第一灰阶值调整为第二灰阶值，第二灰阶值实质上小于对应第一亚像素的第一灰阶值；
按照第二灰阶值驱动第一亚像素进行显示。
具体地，采用上述驱动方法驱动显示面板进行显示时，具体驱动过程如下：
在预设显示模式时，驱动芯片中的调整电路将至少部分第一亚像素在原始画面数据中的第一灰阶值调整为第二灰阶值，该第二灰阶值实质上小于对应第一亚像素的第一灰阶值；驱动芯片中的驱动电路按照第二灰阶值驱动第一亚像素进行显示，使得第一亚像素的显示亮度低于其在原始画面数据中对应的显示亮度；同时，驱动芯片还根据第二亚像素在原始画面数据中对应的灰度值驱动第二亚像素进行显示，使得显示面板处于显示状态。
在采用上述驱动方法驱动显示面板进行显示时，调整电路能够将显示面板中的至少部分第一亚像素在原始画面数据中的第一灰阶值调整为第二灰阶值，且第二灰阶值实质上小于对应第一亚像素的第一灰阶值；驱动电路能够按照第二灰阶值驱动第一亚像素进行显示，使得第一亚像素的实际显示亮度低于该第一亚像素在原始画面数据中对应的显示亮度。因此，在利用本公开实施例提供的驱动方法驱动显示面板进行显示时，能够控制接近非直线延伸的边界处的第一亚像素具有较低的显示亮度，从而弱化用户对显示画面边缘的亮度变化的感知，改善边界区域在显示画面中所出现的锯齿感，更好的提高了画面的显示品质。
而且，本公开的技术方案中不需要通过黑矩阵遮挡第一亚像素来控制其显示亮度，而是通过驱动芯片来控制第一亚像素的显示亮度，因此在利用本公开实施例提供的驱动方法驱动显示面板进行显示时，不用改变显示面板中 黑矩阵的分布，就能够随意调节第一亚像素的透过率，并确认第一亚像素处于不同透过率时显示面板对应的显示效果。可见，在利用本公开实施例提供的驱动方法驱动显示面板进行显示时，不仅弱化了在非直线延伸的边界处出现锯齿感，还避免了彩边显示、浪费生产成本和时间成本等一系列问题。
进一步地，在进入预设显示模式时，将全部第一亚像素在原始画面数据中的第一灰阶值调整为第二灰阶值。
具体地，在进入预设显示模式时，调整电路将全部第一亚像素的灰阶值调整为第二灰阶值，并使第二灰阶值实质上小于对应第一亚像素的第一灰阶值，能够使得显示面板中非直线延伸的边界附近的全部第一亚像素均具有较低的显示亮度，从而进一步改善了显示面板在进行显示时，在非直线延伸的边界处出现的锯齿感，更好的提高了画面的显示品质，改善用户对画面的体验。
进一步地，上述实施例提供的驱动方法还包括：
获取并存储第一亚像素的位置信息；
在进入预设显示模式时，将第一亚像素在原始画面数据中的第一灰阶值调整为第二灰阶值的步骤，包括：
在进入预设显示模式时，查找并获取所存储的位置信息，并根据位置信息，确定第一亚像素，并将第一亚像素对应原始画面的第一灰阶电压调整为第二灰阶电压。
具体地，显示面板中包括的亚像素呈阵列排布，且呈阵列排布的亚像素中，哪些亚像素能够进行有效的显示(即位于显示区域内的亚像素)是在显示面板设计时就已经确定的。驱动芯片能够通过代码一次性将具体有哪些亚像素参与显示，以及各亚像素的位置信息记录在存储单元中，使得显示面板在进行显示时，可根据存储单元中存储的信息实现显示功能，而不需要再次对参与显示的亚像素的位置进行计算，很好的节省了运算量。更详细地说，驱动芯片中包括的存储单元能够获取并存储第一亚像素(需要进行灰阶电压调整的亚像素)的位置信息，和第二亚像素(不需要进行灰阶电压调整，按照原始画面数据进行显示的亚像素)的位置信息。
调整电路在进入预设显示模式时，先在存储单元中查找并获取所存储的 位置信息，并根据该位置信息，从显示面板包括的全部亚像素中确定出哪些是第一亚像素，然后再将确定出的第一亚像素对应原始画面的第一灰阶电压调整为第二灰阶电压，使得第一亚像素的实际显示亮度相对于原始画面数据中对应的显示亮度降低，从而改善该边界区域在显示画面中所出现的锯齿感。
进一步地，上述实施例提供的驱动方法还包括：
存储第一亚像素的gamma校正值；
在进入预设显示模式时，将第一亚像素对应原始画面的第一灰阶电压调整为第二灰阶电压的步骤，包括：
在进入预设显示模式时，查找并获取所存储的第一亚像素对应的gamma校正值，并根据gamma校正值对第一亚像素的Gamma补偿电路的gamma值进行校正，使得Gamma补偿电路基于校正后的gamma值将第一亚像素对应原始画面的第一灰阶电压补偿为第二灰阶电压。
具体地，上述实施例提供的驱动芯片还包括Gamma电路和Gamma补偿电路，其中，Gamma电路用于为第二亚像素提供灰阶电压，该灰阶电压为第二亚像素在原始画面数据中对应的灰阶电压。上述Gamma补偿电路与Gamma电路不是同一电路，该Gamma补偿电路用于控制第一亚像素，能够基于gamma值对第一亚像素的灰阶电压进行补偿。更详细地说，调整电路存储有第一亚像素的gamma校正值，该gamma校正值可以事先通过实验得到，调整电路具体用于在进入预设显示模式时，查找并获取所存储的第一亚像素对应的gamma校正值，并根据gamma校正值对Gamma补偿电路的gamma值进行校正，使得Gamma补偿电路能够基于校正后的gamma值将第一亚像素对应原始画面的第一灰阶电压补偿为第二灰阶电压。

由于利用上述实施例提供的驱动芯片驱动显示装置进行显示时，驱动芯片能够控制接近非直线延伸的边界处的第一亚像素具有较低的显示亮度，弱化用户对显示画面边缘的亮度变化的感知，因此，本公开实施例提供的显示装置在包括上述驱动芯片时，能够改善该边界区域在显示画面中所出现的锯齿感，从而更好的提高了画面的显示品质，改善用户对画面的体验。
而且，由于通过上述驱动芯片能够控制第一亚像素的显示亮度，因此本 公开实施例提供的显示装置在包括上述驱动芯片时，不用改变显示装置中黑矩阵的分布，就能够随意调节第一亚像素的透过率，并确认第一亚像素处于不同透过率时显示装置对应的显示效果，从而实现弱化在非直线延伸的边界处出现锯齿感的效果。

进一步地，处理器还用于在进入预设显示模式时，将全部第一亚像素在原始画面数据中的第一灰阶值调整为第二灰阶值。
进一步地，处理器用于获取并存储所述第一亚像素的位置信息；处理器在进入预设显示模式，将第一亚像素在原始画面数据中的第一灰阶值调整为第二灰阶值时，处理器具体用于在进入预设显示模式时，查找并获取所存储的位置信息，并根据所述位置信息，确定第一亚像素，并将第一亚像素对应原始画面的第一灰阶电压调整为第二灰阶电压。
