下面参考附图和较佳的实施例对本申请作进一步说明。
如图1至图3所示，本申请实施例公布了一种显示面板110的跨压补偿方法，包括步骤：
S11：在当前帧最后一行扫描线扫描完成之后，下一帧第一行扫描线启动之前，传输预设电压信号给面内的数据线；
S12：在传输预设电压信号给面内的数据线的同时，所有扫描线保持关闭状态。
本方案中，如果当前帧最后一行的数据信号电压和下一帧第一行的数据信号电压压差较大，甚至极性相反时，在给下一帧第一行扫描时的扫描时间初期，该数据信号的数据电压将不能迅速达到预设的数据电压，从而造成扫描时间初期充电率不足导致最终充电电压不足的情况和下一帧第一行亮度不足等问题的发生。本方案中，当前帧最后一行扫描线扫描完成之后，下一帧第一行扫描线启动之前即空闲(V-blank)时间，所有的扫描线都保持关闭状态，在V-blank时间内将预设电压信号传输给面内的数据线以先行改变其内的电压，可以使得在当前帧最后一行和下一帧第一行扫描线扫描时，减少甚至避免两行扫描线扫描期间内的数据线内的电压跨压太大的问题，改善当前帧最后一行和下一帧第一行之间的跨压问题，特别是由于不同极性的跨压切换造成的充电不足问题。
在一实施例中，传输预设电压信号给面内的数据线的步骤包括：获取极性与下一帧第一行数据信号的极性相同的预设电压信号；将预设电压信号传输给面内的数据线。
本方案中，当我们可以获知下一帧第一行数据信号的极性时，我们可以将预设电压信号设置为与下一帧第一行数据信号极性相同；例如，当前帧最后一行数据信号的极性与下一帧第一行数据信号的极性相反时，我们在V-blank时间内，先给面内的数据线输入与下一帧第一行极性相同的预设电压信号，如此操作之后，该数据线内的电压准位和下一帧第一行数据信号的电压准位将为同极性，如此，便可以在下一帧第一行扫描时间内迅速达到对应的电压准位，保证扫描时间初期的充电率能够在较高水平，使得最终达到较高的充电电压，减少甚至消除下一帧第一行像素亮度较暗的问题。
在一实施例中，当前帧最后一行的数据信号的极性与下一帧第一行的数据信号的极性相反；获取极性与下一帧第一行数据信号的极性相同的预设电压信号的步骤包括：侦测并根据当前帧最后一行数据信号的极性，获取与当前帧最后一行数据信号极性相反的预设电压信号。
本方案中，我们将电路架构设置为同一数据线当前帧最后一行数据信号和下一帧第一行数据信号极性相反；如此，我们无需获取下一帧第一行数据信号即可获知下一帧第一行数据信号的极性，通过获知当前帧最后一行数据信号的极性间接获知下一帧第一行数据信号的极性，这样我们可以将预设电压信号设置为与下一帧第一行数据信号极性相同；例如，当前帧最后一行数据信号的数据信号为7伏时与下一帧第一行数据信号的为-7伏时，我们在V-blank时间内，先给面内的数据线输入一个负极性的预设电压信号(例如-1伏，-3伏等，但该预设电压信号的电压绝对值不会超过面板设计对应255灰阶数据信号的电压)，如此操作之后，该数据线内的电压准位和下一帧第一行数据信号的电压准位将为同极性，这样便可以在下一帧第一行扫描时间内迅速达到对应的电压准位，保证扫描时间初期的充电率在较高水平，使得最终达到较高的充电电压，这样可以减少下一帧第一行像素亮度较暗的问题，在没有其他任何影响的情况下，甚至可以消除下一帧第一行像素亮度较暗的问题。
在一实施例中，获取极性与下一帧第一行数据信号的极性相同的预设电压信号的步骤包括：在当前帧最后一行扫描线扫描完成之后，下一帧第一行扫描线启动之前，从时序控制芯片120获取下一帧第一行数据信号；侦测并根据下一帧第一行数据信号的极性，获取与下一帧第一行数据信号极性相同的预设电压信号。
本方案中，如图5所示，设置有一提前获取器160，在下一帧数据信号还未传输到面内的情况下，提前从时序控制芯片120处侦测下一帧第一行数据信号的极性，如此，不管是怎么样架构的显示面板110，我们无需管当前帧的数据信号的极性或电压准位，只要从时序控制芯片120处获取下一帧第一行数据信号的极性，即可在V-blank时间内，先给面内的数据线输入一极性与下一帧第一行数据信号极性相同的预设电压信号，保证扫描时间初期的充电率在较高水平，使得最终达到较高的充电电压，减少甚至消除下一帧第一行像素亮度较暗的问题；另外，仅获取下一帧第一行数据信号的极性，则我们对应预设电压信号只要设计较少的电压转换，例如对应255灰阶的数据信号电压为±7伏，则我们可以将预设电压信号设置为3.5伏或-3.5伏，必要是可以再设计一个0伏(例如下一帧第一行的数据信号为0伏时，可以将预设电压信号设为0伏，即认为0伏对应的极性相同为0伏)，如此，便能够对应下一帧第一行数据信号为正极性、负极性和0伏的时候，分别进行加压操作，设计简单。
在一实施例中，获取极性与下一帧第一行数据信号的极性相同的预设电压信号的步骤包括：在当前帧最后一行扫描线扫描完成之后，下一帧第一行扫描线启动之前，从时序控制芯片120获取下一帧第一行数据信号；侦测并根据下一帧第一行数据信号，获取与下一帧第一行数据信号极性数据相同的预设电压信号。
本方案中，设置有一提前获取器160，在下一帧数据信号还未传输到面内的情况下，提前从时序控制芯片120处侦测下一帧第一行数据信号，如此，不管是怎么样架构的显示面板 110，我们无需管当前帧的数据信号的极性或电压准位，只要从时序控制芯片120处获取下一帧第一行数据信号，即可在V-blank时间内，先给面内的数据线输入与该下一帧第一行数据信号相同的预设电压信号，如此操作之后，该数据线内的电压准位和下一帧第一行数据信号的电压准位将相同，如此便可以在下一帧第一行扫描时间从启动时起就达到要的电压准位，保证整个扫描时间的充电率一种处在对应数据信号的水平，使得显示面板110最终达到较高的充电电压甚至达到预设的充电电压，减少甚至消除下一帧第一行像素亮度较暗的问题。
在一实施例中，当前帧最后一行的数据信号的极性，与下一帧第一行的数据信号的极性相反；传输预设电压信号给面内的数据线的步骤中，预设电压信号的电压为0伏。
本方案中，不管该当前帧最后一行和下一帧第一行的极性是否相同，现将面内的数据线电压调到0伏的电压准位，即不管下一帧第一行数据信号如何，预设电压信号均设置为0伏。我们这样设计能够保证面内数据线的电压和下一帧第一行数据信号的电压准位不会相差太大,例如,当前帧最后一行的极性电压为5伏,下一帧第一行的极性电压为10伏,我们先将面内数据线电压调到0伏，特别是当前帧最后一行和下一帧第一行极性相反的时候，如果先将面内的数据线电压先调到0伏的电压准位,那么面内数据线的电压和下一帧第一行数据信号的电压准位相差与没有将面内的数据线电压先调到0伏的电压准位面内数据线的电压和下一帧第一行数据信号的电压准位相差相对更加明显,能够达到较好的减少跨压,保证扫描时间初期的充电率在较高水平，使得显示面板110最终达到较高的充电电压，减少甚至消除跨压问题对像素亮度的影响。
在一实施例中，侦测并根据当前帧最后一行数据信号的极性的步骤包括:时序控制芯片120检测到源极驱动器的极性反转信号(polarity inversion signal for source driver，POL)切换到当前帧时，计数器开始计数扫描行数；当前扫描行数等于预设最大行数，侦测当前扫描行的数据信号的极性作为最后一行数据信号的极性。
本方案中，如图4所示，我们在此处添加设置计数器，可以计数什么时候达到了当前帧最后一行，什么时候达到了v-blank,，极性反转信号会在V-blank时间做切换，首先利用时序控制芯片120来侦测极性反转信号的切换，当侦测到极性反转信号有切换后，再侦测行计数器162的数值，计算当前数据传输到哪一行，只要在第一行进行输出前完成即可。时序控制芯片120会根据行计数器162的数值，来决定是否输出预设电压信号；比如现在全高清(Full High Definition，FHD)解析度的显示面板110，考虑到V-blank的时间，总行数会达到1125行，所以时序控制芯片120侦测到目前是第1125行时，认为已经传输到最后一行了，此时便将默认存储器130(可以是数据信号存储器)中的预设电压信号取出进行输出，通过数据驱动芯片140转化为实际的电压输出，在下一帧第一行的输出前，提前将面内传输线上 的电压提前改变为同一极性(在保持栅线关闭的情况下)，完成跨压补偿的过程。其中默认存储的预设电压信号可以取黑画面的数据，也可以根据下一帧第一行的实际电压信号，来取更合适的数值。
作为本申请的另一实施例，参考图4所示，公开了一种显示面板110，包括：时序控制芯片120(Timing Controller IC，TCON IC)，控制栅极驱动电路和源极驱动电路；预补偿电路150，输出预设电压信号；默认存储器130，存储预设电压信号，通常也叫作默认data存储；数据驱动芯片140(Data driver)，传输数据信号到显示面板110内的数据线；时序控制芯片120，在当前帧最后一行扫描完成之后，下一帧第一行扫描启动之前，在保持栅极驱动电路关闭的同时，将预设电压信号输入到显示面板110的数据线。
本方案中，将时序控制芯片120输出给数据驱动芯片140的源极驱动器的极性反转信号拉回做侦测，源极驱动器的极性反转信号控制数据驱动芯片140输出电压的正负极性；预补偿电路150是根据源极驱动器的极性反转信号和时序控制芯片120，确定预设电压信号，时序控制芯片120,在V-blank时间，保持栅极驱动电路关闭的同时，将预设电压信号输入到显示面板110的数据线。如图2所示，前一帧切换到下一帧第一行进行充电的时候，由于正负极性的切换，会造成数据线上的电压从准位a开始切换，如果当前帧最后一行的数据信号电压和下一帧第一行的数据信号电压压差较大，甚至极性相反时，在给下一帧第一行扫描时的扫描时间初期，该数据信号的数据电压将不能迅速达到预设的数据电压，例如，如图2所示，准位a和准位b的电压差距很大，所以会造成最终充电电压只能到b’的位置，与目标b会有△V的差距，从而造成扫描时间初期充电率不足导致最终充电电压不足的情况和下一帧第一行亮度不足等问题的发生。本方案中，当前帧最后一行扫描线扫描完成之后，下一帧第一行扫描线启动之前即空闲(V-blank)时间，所有的扫描线都保持关闭状态，在V-blank时间内，将预设电压信号传输给面内的数据线以先行改变其内的电压，可以使得在当前帧最后一行和下一帧第一行扫描线扫描时，减少甚至避免两行扫描线扫描期间内的数据线内的电压跨压太大的问题，改善当前帧最后一行和下一帧第一行之间的跨压问题，特别是由于不同极性的跨压切换造成的充电不足问题，可以达到如图3所示的效果。如图3是本方案的效果示意图，POL在V-blank时间内切换后，在当前帧最后一行传输预设电压信号，本效果以默认预设电压信号为黑画面数据举例，电压准位会经由黑色实线由准位a慢慢切换至0，然后在下一帧的第一行开始输出时，由于电压准位提前从a降为了0，电压的切换就可以从0准位开始切换至准位b，那么在相同的充电时间内就更加容易到达，从而保证了第一行的充电效果。
在一实施例中，预补偿电路150包括提前获取器160，提前获取器160包括主控器161(Microcontroller Unit，MCU)和行计数器162，主控器161和行计数器162设置控制芯片上，提前获取器160从控制芯片内获取下一帧第一行的数据信号。
本方案中，提前获取器160，在下一帧数据信号还未传输到面内的情况下，提前从时序控制芯片120处侦测下一帧第一行数据信号，POL信号会在V-blank时间做切换，因此会首先利用MCU(主控器161)来侦测POL的切换，当侦测到POL有切换后，行计数器162再侦测行计数器162的数值，计算当前数据传输到哪一行，跨压补偿只要在第一行进行输出前完成即可，所以TCON会根据行计数器162的数值，来决定是否输出预设电压信号，如此，不管是怎么样架构的显示面板110，我们无需管当前帧的数据信号的极性或电压准位，只要从时序控制芯片120处获取下一帧第一行数据信号，即可在V-blank时间内，先给面内的数据线输入与该下一帧第一行数据信号相同的预设电压信号，保证整个扫描时间的充电率一种处在对应数据信号的水平，使得显示面板110最终达到较高的充电电压甚至达到预设的充电电压，减少甚至消除下一帧第一行像素亮度较暗的问题。
作为本申请的另一实施例，参考图6所示，公开了一种显示装置100，包括如上的显示面板110。

以上内容是结合具体的优选实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
