消除面板上关机残影的方法及装置
相关申请

技术领域
本申请涉及显示技术领域，尤其涉及消除面板上关机残影的方法及装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。
为了降低液晶显示器的色偏，提高可视角范围，对液晶显示器通常会做低色偏(low color shift)的设计。一般的做法是通过增加像素的区域，一个像素一般可以分成4个区域。但是，如果将一个像素分为主像素区和次像素区，就可以增加到8个区域，从而改善色偏情况，提高可视角度。具体地，采用多个不同的薄膜晶体管（Thin Film Transistor，TFT）对像素区域供电（3T像素设计），即采用三个TFT为两个像素区域充放电。在栅极（gate line）打开时，通过主TFT和次TFT将电荷分别送至像素的主像素区和次像素区。栅极关闭后，电荷共享（charge sharing）TFT打开，将次像素区中的部分电荷释放到电荷共享的电容中。从而，次像素区与主像素区之间呈现出电位差，液晶的倾斜角度产生差异，达到降低色偏的效果。
对于上述做了低色偏设计的液晶显示器，在采用驱动集成电路上的准位控制信号（XON）功能来开启所有像素电极的薄膜电晶体，以使像素区域进行快速放电的方法解决关机残影问题时，栅极全开电荷共享TFT一直开启，储存电极（Array Com，简称ACom）与数据线（data line）连通，阵列储存的电能流向数据线，导致数据准位被升高或降低，因而，数据线电压准位与参考电极（CF Com，简称CCom）电压间的夹压较大，导致像素区域中的电荷无法完全释放，关机残影得不到消除。

参照图2，本申请消除面板上关机残影的方法一实施例，所述消除面板上关机残影的方法包括：
步骤S10，获取数据线的初始电压以及参考电极的设定电压；
步骤S20，在显示面板关机时，获取所述数据线的当前电压；
由于液晶显示器在显示图像时，会在两相对电极( 如参考电极及像素电极) 之间的储存电容中累积电荷。当液晶显示器的显示面板关断电源时，这些累积电荷将会使相应的像素处于不同的灰阶，从而在显示屏上残留一些图像。
为了解决液晶显示器关机残影问题，现有技术中是在液晶显示器电源关闭后使用驱动集成电路(IC) 上的准位控制信号（Xon）功能来开启所有像素结构的薄膜电晶体，以使像素区域进行快速放电。这里的Xon 功能是指，栅极驱动集成电路的Xon引脚收到显示面板的关机信号后，栅极驱动集成电路将所有输出端的输出电压都拉升至高电位电压，开启液晶显示面板中所有的薄膜晶体管的栅极，以强制性将像素结构中的电荷快速地中和、释放掉，来达到消除残影的目的。
然而，对于有些显示面板，在开启所有像素结构的薄膜电晶体时，电荷共享薄膜晶体管（charge sharing TFT ）一直开启，储存电极（Array Com，简称A Com）与数据线（data line）连通，阵列储存的电能流向数据线，导致数据线电压准位被升高或降低，从而使得数据电压线准位与参考电极的电压间的夹压较大，像素结构中的电荷无法有效释放，关机时，显示面板中的残影得不到消除。例如，图3所示的低色偏设计的显示面板，在显示面板关机时，Tcs打开，A Com与Data连通，A Com中的电能流向Data。
为避免储存电极对数据线的电压的影响，本申请提供一种消除面板上关机残影的方法，在显示面板关机前，通过电压检测元件检测数据线的初始电压（正半周电压）以及参考电极的设定电压。在显示面板关机后，检测数据线的当前电压（正半周电压）。
步骤S30，根据所述数据线的初始电压以及所述数据线的当前电压更新所述参考电极的设定电压。
将显示面板的控制系统中的参考电极设置为设定电压可调变，在显示面板关机时，根据数据线的初始电压以及数据线的当前电压更新参考电极的设定电压的设定电压，使得数据线的当前电压下对应的电压准位与更新后参考电极的设定电压间的夹差小于一定值。从而，像素结构中的电荷得到有效释放，显示面板画面变黑，解决残影问题。
其中，根据显示面板的不同型号，在显示面板关机后，能够使得面板黑化消除关机残影的夹差不同。通常，该夹差的取值范围为[-0.5V~0.5V]。
例如，在显示面板关机前，检测到数据线的初始电压为4V，参考电极的设定电压为2V。当显示面板关机时，检测到数据线的当前电压为5V，与初始电压的电压差为1V。则，将参考电极的设定电压更新为3V（4V+1V）。即，在数据线受到储存电极的影响之后，数据线的电压准位变化了1V，此时，将参考电极的设定电压也相应调整1V，从而数据线电压准位与参考电极电压的夹压不变，像素结构中的电荷得到释放，显示面板画面变黑，解决残影问题。应当指出的是，在此例子中，若夹差的取值为[-0.3V~0.3V]，则，参考电极的设定电压更新为4.7 V ~5.3V中的任意值均可解决关机残影问题。
如图4所示，显示面板关机后，储存电极（A Com）影响电极线（Data）的电压，将电极线的电压准位（电极线的电压准位，在电极线的正半周电压与负半周电压的中间，图中未示出）拉走。电极向的电压准位与参考电极（C Com）的设定电压之间存在较大夹压。将参考电极的设定电压更新之后，如图5所示，随着参考电极（C Com）的电压变化小电极线的电压准位与参考电极（C Com）电压之间的夹压缩小，像素结构中的电荷得到释放，显示面板画面变黑，解决残影问题。
此外，参考电极的设定电压的更新方法，不限定于本实施例提供的上述方法，凡是设定电压更新后的，能够达到如下效果的参考电极的设定电压的更新方法均属于本申请的保护范围。所述效果为：更新后参考电极的设定电压与数据线的电压准位间的夹压小于一定的电压。
在本实施例中，在显示面板关机前，通过电压检测元件检测数据线的初始电压以及参考电极的设定电压。在显示面板关机后，检测数据线的当前电压。将显示面板的控制系统中的参考电极设置为设定电压可调变，在显示面板关机时，根据数据线的初始电压以及数据线的当前电压更新参考电极的设定电压的设定电压，使得数据线的当前电压下对应的电压准位与更新后的所述设定电压的夹差小于一定值。从而，像素结构中的电荷得到有效释放，显示面板画面变黑，解决残影问题。
进一步的，参照图6，本申请消除面板上关机残影的方法另一实施例，基于上述第一实施例，所述步骤S30包括：
步骤S31，获取所述数据线的初始电压与所述当前电压的电压差。
步骤S32，根据所述电压差更新所述参考电极的设定电压。
参考电极的设定电压的更新方法可为：首先计算数据线的初始电压与当前电压压的电压差，根据电压差来更新参考电极的设定电压。在根据电压差来更新参考电极的设定电压时，将参考电极更新前的设定电压与所述电压差相加得到电压和，再根据电压和来更新设定电压。具体地，根据所述电压和确定调变电压，将所述调变电压作为所述参考电极更新后的设定电压，其中，所述调变电压与所述电压和的差值在第一预设范围内，以使在更新后的设定电压与数据线的电压准位间的夹压小于一定的电压。
此外，设定的电压的更新方法还可为：在获取到数据线的初始电压与当前电压的电压差之后，根据电压差来确定调变电压差，根据调变电压差来更新参考电极的设定电压。具体地，可将调变电压差与更新前的设定电压之和作为更新后的设定电压。同理，所述调变电压差与所述电压差的差值在第二预设范围内，以使在更新后的设定电压与数据线的电压准位间的夹压小于一定的电压。
需要指出的是，本申请所述的电压差包含正值和负值，在电压差与其他参数作和时，应当将电压差的正负带入。
其中，根据显示面板的不同型号，设置不同的第一预设范围值以及第二预设范围。在数据线电压准位与参考电极设定电压间的夹压小于一定电压时，显示面板关机后，能够使得面板黑化。通常，该第一预设范围值以及第二预设范围的取值区间包含在[-0.5V~0.5V]内。在本实施例中，第一预设范围可与第二预设范围相同，也可不同。
在本实施例中，获取所述数据线的初始电压与当前电压的电压差，再根据所述电压差更新所述参考电极的设定电压。通过数据线的初始电压与当前电压的电压差来参考电极的调节设定电压，能够确保参考电极更新后的设定电压与数据线电压准位间的夹压在面板黑化范围内，有效地解决显示面板关机残影的问题。
进一步的，参照图7，本申请消除面板上关机残影的方法又一实施例，基于上述实施例，所述步骤S30之前，还包括：
步骤S40，获取所述数据线的当前电压与所述数据线的初始电压的电压差；
步骤S50，判断所述电压差的绝对值是否大于预设阈值；
当所述电压差的绝对值大于预设阈值时，执行步骤S30，即根据所述数据线的初始电压以及所述数据线的当前电压更新所述参考电极的设定电压。
在获取到数据线的初始电压和当前电压之后，先计算该当前电压与初始电压的电压差。如果电压差的绝对值在一定预设阈值内，则表明储存电极收到关机前最后一个画面的像素影响较小，电压变化不大，使得在储存电极的影响下数据线的电压变化在一定可接受的范围内，数据线的电压准位偏移量较小，能够将像素结构中的电荷能够得到释放后，满足显示面板画面变黑要求，不会出现关机残影现象；反之，电压差的绝对值大于一定预设阈值，则储存电极的当前电压对数据线电压的影响较大，数据线的电压准位偏移量过大，无法使得显示面板变黑，出现关机残影现象。
故，在显示面板的控制系统中增加所述电压差的绝对值是否大于预设阈值的判断，当电压差的绝对值大于预设阈值时，执行步骤S30，调节参考电极的设定电压；当电压差的绝对值大于预设阈值时，则无需设定电压的调节操作。减少程序操作，提高使用关机效率。
进一步的，在判断是否需要更新参考电极的设定电压时，在获取面板关机前最后一个画面的像素灰阶，当灰阶很低，画面亮度低时，画面像素对储存电极的电压影响较小，在此，将不对储存电极的设定电压进行更新。
在本实施例中，在获取到数据线的初始电压和当前电压之后，先计算该当前电压与初始电压的电压差。判断所述电压差的绝对值是否大于预设阈值的判断，当电压差的绝对值大于预设阈值时，执行步骤S30，调节参考电极的设定电压；当电压差的绝对值大于预设阈值时，则无需设定电压的调节操作。减少程序操作，提高使用关机效率。
进一步的，参照图8，本申请消除面板上关机残影的方法再一实施例，基于上述实施例，所述步骤S20之前，还包括：
步骤S60，在显示面板关机时，检测所述显示面板的驱动中的电荷共享薄膜晶体管是否与数据线连通。
当所述电荷共享薄膜晶体管与所述数据线连通时，执行步骤S20，即获取所述数据线的当前电压。
当显示面板的电荷共享薄膜晶体管与数据线连通时，导致储存电极中存储的电能流向数据线，影响数据线的电压，数据线电压准位与参考电极的设定电压间的夹压增大，最终导致像素区域的从而使得像素结构中的电荷不能够得到有效地释放，造成显示面板关机残影的问题。
因此，在显示面板在显示面板关机时，检测所述显示面板的驱动中的电荷共享薄膜晶体管是否与数据线连通。在显示面板的驱动中的电荷共享薄膜晶体管与数据线连通时，执行更新参考电极的设定电压的步骤，解决关机残影问题；反之，在显示面板的驱动中的电荷共享薄膜晶体管没有与数据线连通时，则关机时，储存电极中存储的电能不能够流向数据线，数据线的电压不会受到影响，无需对参考电极的设定电压更新，也可以避免显示面板关机残影现象的发生。
此外，当显示面板的驱动中的栅极线全开时，电荷共享薄膜晶体管必然与数据线连通。故，在显示面板关机时，判断栅极线是否全开，当所述栅极线全开时，执行更新参考电极的设定电压的操作，解决关机残影问题。
在本实施例中，在显示面板在显示面板关机时，检测所述显示面板的驱动中的电荷共享薄膜晶体管是否与数据线连通。在显示面板的驱动中的电荷共享薄膜晶体管与数据线连通时，执行更新参考电极的设定电压的步骤，解决关机残影问题；反之，在显示面板的驱动中的电荷共享薄膜晶体管没有与数据线连通时，则无需对参考电极的设定电压更新，也可以避免显示面板关机残影现象的发生。
此外，本申请实施例还提出一种消除面板上关机残影的方法。
参照图9，本申请消除面板上关机残影的方法再又一实施例，所述消除面板上关机残影的方法包括以下步骤：
步骤S70，获取数据线的初始电压以及参考电极电压；
在显示面板关机前，通过电压检测元件检测数据线的初始电压（正半周电压）以及参考电极的设定电压。
步骤S80，在面板关机时，检测所述面板的驱动中的电荷共享薄膜晶体管是否与数据线连通；
当显示面板的电荷共享薄膜晶体管与数据线连通时，导致储存电极中存储的电能流向数据线，影响数据线的电压，数据线电压准位与参考电极的设定电压间的夹压增大，最终导致像素区域的从而使得像素结构中的电荷不能够得到有效地释放，造成显示面板关机残影的问题。
步骤S90，当所述电荷共享薄膜晶体管与数据线连通时，获取所述数据线的初始电压与所述当前电压的电压差；
步骤S100，根据所述电压差更新所述参考电极的设定电压。
在显示面板在显示面板关机时，检测所述显示面板的驱动中的电荷共享薄膜晶体管是否与数据线连通。在显示面板的驱动中的电荷共享薄膜晶体管与数据线连通时，通过电压检测元件检测数据线的当前电压，并计算数据线的当前电压与初始电压的电压差。
将显示面板的控制系统中的参考电极设置为设定电压可调变，在显示面板关机时，根据数据线的初始电压以及数据线的当前电压更新参考电极的设定电压的设定电压，使得数据线的当前电压下对应的电压准位与更新后参考电极的设定电压间的夹差小于一定值。从而，像素结构中的电荷得到有效释放，显示面板画面变黑，解决残影问题。
其中，根据显示面板的不同型号，在显示面板关机后，能够使得面板黑化消除关机残影的夹差不同。通常，该夹差的取值范围为[-0.5V~0.5V]。
例如，在显示面板关机前，检测到数据线的初始电压为4V，参考电极的设定电压为2V。当显示面板关机时，检测到数据线的当前电压为5V，与初始电压的电压差为1V。则，将参考电极的设定电压更新为3V（4V+1V）。即，在数据线受到储存电极的影响之后，数据线的电压准位变化了1V，此时，将参考电极的设定电压也相应调整1V，从而数据线电压准位与参考电极电压的夹压不变，像素结构中的电荷得到释放，显示面板画面变黑，解决残影问题。应当指出的是，在此例子中，若夹差的取值为[-0.3V~0.3V]，则，参考电极的设定电压更新为4.7 V ~5.3V中的任意值均可解决关机残影问题。
如图4所示，显示面板关机后，储存电极（A Com）影响电极线（Data）的电压，将电极线的电压准位（电极线的电压准位，在电极线的正半周电压与负半周电压的中间，图中未示出）拉走。电极向的电压准位与参考电极（C Com）的设定电压之间存在较大夹压。将参考电极的设定电压更新之后，如图5所示，随着参考电极（C Com）的电压变化小电极线的电压准位与参考电极（C Com）电压之间的夹压缩小，像素结构中的电荷得到释放，显示面板画面变黑，解决残影问题。
此外，参考电极的设定电压的更新方法，不限定于本实施例提供的上述方法，凡是设定电压更新后的，能够达到如下效果的参考电极的设定电压的更新方法均属于本申请的保护范围。所述效果为：更新后参考电极的设定电压与数据线的电压准位间的夹压小于一定的电压。
进一步的，参考电极的设定电压的更新方法可为：首先计算数据线的初始电压与当前电压压的电压差，根据电压差来更新参考电极的设定电压。在根据电压差来更新参考电极的设定电压时，将参考电极更新前的设定电压与所述电压差相加得到电压和，再根据电压和来更新设定电压。具体地，根据所述电压和确定调变电压，将所述调变电压作为所述参考电极更新后的设定电压，其中，所述调变电压与所述电压和的差值在第一预设范围内，以使在更新后的设定电压与数据线的电压准位间的夹压小于一定的电压。
此外，设定的电压的更新方法还可为：在获取到数据线的初始电压与当前电压的电压差之后，根据电压差来确定调变电压差，根据调变电压差来更新参考电极的设定电压。具体地，可将调变电压差与更新前的设定电压之和作为更新后的设定电压。同理，所述调变电压差与所述电压差的差值在第二预设范围内，以使在更新后的设定电压与数据线的电压准位间的夹压小于一定的电压。
需要指出的是，本申请所述的电压差包含正值和负值，在电压差与其他参数作和时，应当将电压差的正负带入。
其中，根据显示面板的不同型号，设置不同的第一预设范围值以及第二预设范围。在数据线电压准位与参考电极设定电压间的夹压小于一定电压时，显示面板关机后，能够使得面板黑化。通常，该第一预设范围值以及第二预设范围的取值区间包含在[-0.5V~0.5V]内。在本实施例中，第一预设范围可与第二预设范围相同，也可不同。
进一步的，在获取到数据线的初始电压和当前电压之后，先计算该当前电压与初始电压的电压差。判断所述电压差的绝对值是否大于预设阈值的判断，当电压差的绝对值大于预设阈值时，执行步骤S30，调节参考电极的设定电压；当电压差的绝对值大于预设阈值时，则无需设定电压的调节操作。减少程序操作，提高使用关机效率。
进一步的，在显示面板在显示面板关机时，检测所述显示面板的驱动中的电荷共享薄膜晶体管是否与数据线连通。在显示面板的驱动中的电荷共享薄膜晶体管与数据线连通时，执行更新参考电极的设定电压的步骤，解决关机残影问题；反之，在显示面板的驱动中的电荷共享薄膜晶体管没有与数据线连通时，则无需对参考电极的设定电压更新，也可以避免显示面板关机残影现象的发生。
进一步的，当显示面板的电荷共享薄膜晶体管与数据线连通时，导致储存电极中存储的电能流向数据线，影响数据线的电压，数据线电压准位与参考电极的设定电压间的夹压增大，最终导致像素区域的从而使得像素结构中的电荷不能够得到有效地释放，造成显示面板关机残影的问题。
因此，在显示面板在显示面板关机时，检测所述显示面板的驱动中的电荷共享薄膜晶体管是否与数据线连通。在显示面板的驱动中的电荷共享薄膜晶体管与数据线连通时，执行更新参考电极的设定电压的步骤，解决关机残影问题；反之，在显示面板的驱动中的电荷共享薄膜晶体管没有与数据线连通时，则关机时，储存电极中存储的电能不能够流向数据线，数据线的电压不会受到影响，无需对参考电极的设定电压更新，也可以避免显示面板关机残影现象的发生。
此外，当显示面板的驱动中的栅极线全开时，电荷共享薄膜晶体管必然与数据线连通。故，在显示面板关机时，判断栅极线是否全开，当所述栅极线全开时，执行更新参考电极的设定电压的操作，解决关机残影问题。
在本实施例中，在显示面板关机前，通过电压检测元件检测数据线的初始电压以及参考电极的设定电压。在显示面板关机后，检测所述显示面板的驱动中的电荷共享薄膜晶体管是否与数据线连通。在显示面板的驱动中的电荷共享薄膜晶体管与数据线连通时，检测数据线的当前电压。将显示面板的控制系统中的参考电极设置为设定电压可调变，在显示面板关机时，根据数据线的初始电压以及数据线的当前电压更新参考电极的设定电压的设定电压，使得数据线的当前电压下对应的电压准位与更新后的所述设定电压的夹差小于一定值。从而，像素结构中的电荷得到有效释放，显示面板画面变黑，解决残影问题。
此外，本申请实施例还提出一种消除面板上关机残影的装置，其中，所述消除面板上关机残影的装置包括：储存器、处理器及储存在所述储存器上并可在所述处理器上运行的关机残影的消除程序，所述关机残影的消除程序被所述处理器执行时实现如上各个实施例所述的消除面板上关机残影的方法。
