在时序控制器的控制下， 栅极驱动集成电路驱动与栅极线连接的薄膜场 效应晶体管的栅极开启或关闭， 在薄膜场效应晶体管的栅极开启时， 与薄膜 场效应晶体管连接的电容开始充电， 源极驱动集成电路驱动源极线输出相应 的驱动信号。
根据现有的驱动方式， 如图 2所示， 栅极驱动集成电路的每条栅极线与 一行 TFT的栅极连接 ,源极驱动集成电路的每条源极线与一列 TFT的源极连 接。 在进行画面显示时， 同一时间， 开启一行 TFT的栅极。
为了减少闪烁以保证画面显示质量， 通过改变源极驱动集成电路驱动源 极线输出的驱动信号的极性进行像素翻转， 在像素翻转方式中， 点翻转（dot inversion ) 方式得到的画面品质最好， 闪烁最小。
点翻转的效果图如附图 3所示，该翻转方式的核心思想是第 Y帧画面下， 每相邻两条源极线上的极性相反； Y+1帧画面下同一条源极线上的电压与 Y 帧画面时的极性相反， 且每相邻两条源极线上的极性相反， 从而达到既能防 止液晶老化又能降低功耗的目的， 其中 Y为大于等于 1的整数。
但是如附图 2和附图 3所示， 基于该结构下釆用点翻转方式在同一画面 下每经过一个扫描线扫描时间后， 每条数据线（源极线）所载的驱动信号的 极性就要翻转一次， 因而消耗大量的能量， 并且容易使液晶显示面板上源极 驱动集成电路的温度升高。 例如为了实现点翻转的效果， 假设第一行第一列 的红色子像素上的电压极性为正， 第二行第一列的红色子像素对应的电压极 性就要为负， 因此当栅极驱动器从驱动第一行转为第二行时， 第一条源极线 S1上的极性就会由正变为负。 发明内容

下面结合附图和实施例对本发明提供的显示面板及其驱动方法进行更详 细地说明。
本发明实施例提供一种显示面板， 包括以阵列分布的多个 TFT的显示基 板、 通过源极线（ Source线 )驱动 TFT源极的源极驱动集成电路、 通过栅极 线（ Gate线 )驱动 TFT栅极的栅极驱动集成电路。 在显示面板上， 一个 TFT 对应一个子像素 （Sub Pixel ), 子像素是构成像素的基本元素。
本实施例中， 栅极驱动集成电路连接多条栅极线， 每条栅极线连接相邻 的 N行 TFT的栅极， 1<N < TFT总行数， 且不同栅极线连接不同行的 TFT 的栅极， 即各栅极线连接的 TFT所在的行不重叠，每行 TFT的栅极仅与一条 栅极线连接；
源极驱动集成电路连接多条源极线， 连接在同一条栅极线上的不同 TFT 的源极分别与不同的源极线连接， 且连接在不同栅极线上、 位于同一列并间 隔 g*N-l个 TFT的 TFT的源极连接在同一条源极线上， g为正整数，且 N<g*N < TFT总行数。
优选地， 栅极驱动集成电路按扫描顺序逐条驱动各栅极线， 由于一条栅 极线连接多行 TFT的栅极， 从而驱动与该条栅极线连接的 N行 TFT的栅极 同时开通， 在 N行 TFT的栅极开通时， 源极驱动集成电路驱动各源极线输出 相应的驱动信号， 以实现像素翻转。
本发明实施例中， 改变传统驱动方式中同一时间只有一行子像素对应的
TFT的栅极开启的方式， 在同一时间内， 多行子像素对应的 TFT的栅极同时 开启， 因此开启时间可以稍长一些， 保证了每个 TFT上栅极的开启时间， 从 而保证了画面的显示效果。 本发明实施例中， 由于驱动一条栅极线， 多行子 像素对应的 TFT的栅极同时开启， 因此栅极线减少为原来的 1/N, 因此扫描 次数也减少为原来的 1/N, 每条数据线 （源极线）所载的驱动信号的极性每 两帧翻转一次， 从而大大降低了功耗， 不会使液晶显示面板上源极驱动集成 电路的温度升高。
优选地，源极驱动集成电路驱动各源极线输出相应的驱动信号具体包括： 对于同一帧画面， 每相邻两个 TFT的源极连接的源极线输出的驱动信号极性 相反； 对于相邻的两帧画面， 同一 TFT的源极连接的源极线输出的驱动信号 极性相反， 从而实现点翻转效果。
本发明实施例对显示面板上分布的子像素的种类及子像素的排列方式不 作限定。
如图 4所示， 现有技术每个像素由红、 绿、 蓝（RGB )三个子像素组成， 由于液晶每个像素由 RGB三个子像素组成， 通过液晶分子后依靠 RGB像素 组合成任意颜色光， 因此 RGB三原色越鲜艳， 那么可以表示的颜色范围就越 广； 反之， 三原色不鲜艳， 所能显示的颜色范围就窄。 现阶段， 因为其无法 显示比三原色更鲜艳的颜色，应用 RGB三原色技术并不能全面还原自然界人 眼所能感知的色彩， 传统三原色在黄色和蓝绿色领域的色彩表现能力不足。
依照本发明优选实施例， 所述显示面板上分布有组成像素的红、 绿、 蓝 和白 （RGBW ) 四种子像素， 各像素的四种子像素呈横向一字分布或呈矩形 分布； 或者， 所述显示面板上分布有组成像素的红、 绿、 蓝、 黄（RGBY ) 四种子像素， 每个像素的四种子像素呈横向一字分布或呈矩形分布。 当然， 根据实际需要， 还可以釆用其它颜色的子像素来构成每个像素， 而且构成每 个像素的子像素的数量也不限于四种。
优选地， 呈一字分布时， R、 G、 B、 W四种子像素依次排列呈一字分布， 当然， 也可以是其他排列方式。 或者， R、 G、 B、 Y四种子像素依次排列呈 一字分布， 当然， 也可以是其他排列方式。
优选地， 呈矩形分布时， 每个像素的 R、 G依次排列在上面一行， B、 W 依次排列在下面一行。 或者， 每个像素的 R、 G依次排列在上面一行， B、 Y 依次排列在下面一行。
本实施例改变传统驱动方式中同一时间只有一行栅极开启的方式， 保证 充电电容的充电时间， 保证了显示效果， 同时还改变现有液晶面板的像素排 列形式， 以 RGBW-子像素替代原有的 RGB子像素， 其中， R-G-B决定像素 显示的颜色， W增加像素显示的亮度； 或以 RGBY子像素替代原有的 RGB 子像素， 以实现更广阔的色域。
当然， 还可以在核心思想不变的情况下将白色或黄色像素变为其他子像 素， 以便增加相应颜色的表现力或使某一子像素 （某几个子像素） 更大或更 小以增加或减小相应颜色的表现力。 RGBW或 RGBY像素相对位置排布亦可 在核心思想不变的情况下做相应变化。
同样， 为了实现像素逐行显示的效果， 每条栅极线连接的 N行 TFT显示 时呈现完整的像素点， 优选地， 本实施例中， 每条栅极线连接的 TFT行数 N 为 2的倍数。 优选地， 每个像素的四种子像素呈横向一字分布或者矩形分布 时， N为 4的倍数。 这样在每个像素的子像素呈横向一字分布或呈矩形分布 时， 可以保证显示的是完整的像素点。 进一步优选地， 本实施例中 N为 4。
本发明还实施例还提供一种显示装置， 该显示装置包括上述实施例提供 的显示面板， 这里不再详述显示面板的具体结构。
本发明实施例还提供一种上述显示面板的驱动方法， 包括：
栅极驱动集成电路按扫描顺序逐条驱动各栅极线 , 从而同时驱动与栅极 线连接的 N行 TFT的栅极开通；
在 N行 TFT的栅极开通时，源极驱动集成电路驱动各源极线输出相应的 驱动信号。
优选地， 一个 TFT对应一个子像素， 源极驱动集成电路驱动各源极线输 出相应的驱动信号， 使所述子像素呈现点翻转的翻转方式。
优选地， 源极驱动集成电路驱动各源极线输出相应的驱动信号， 使所述 子像素呈现点翻转的翻转方式， 具体包括：
对于同一帧画面， 每相邻两个 TFT的源极连接的源极线输出的驱动信号 极性相反； 对于相邻的两帧画面， 同一 TFT的源极连接的源极线输出的驱动 信号极性相反。
下面以釆用四种子像素为例给出本发明显示面板的优选实施例。 实施例 1
本实施例中显示面板由一个以阵列分布的多个 TFT的显示面板、 一个驱 动 TFT源极的带有源极线的源极驱动集成电路、一个驱动 TFT栅极的带有栅 极线的栅极驱动集成电路以及背光模块组成。 显示面板上的像素阵列 （Pixel Array )分布示意图如图 5所示， 每个像素由 RGBW四种子像素组成， 每个 像素的四种子像素 RGBW呈横向一字分布。
栅极驱动集成电路的每条栅极线连接相邻 4行 TFT的栅极， 且不同栅极 线连接不同行的 TFT的栅极；连接在同一条栅极线上的不同 TFT的源极分别 与不同的源极线连接，且连接在不同栅极线上位于同一列并间隔 g*4-l个 TFT 的 TFT的源极连接在同一条源极线上， g为正整数。 如连接在第 1条栅极线 D1上、 位于第 1行第 1列的 TFT, 与连接在第 2条栅极线 D2上、 位于第 5 行第 1列的 TFT连接在 S1上； 连接在第 1条栅极线 D1上、 位于第 2行第 1 列的 TFT, 与连接在第 2条栅极线 D2上、 位于第 6行第 1列的 TFT连接在 S2上； 连接在第 1条栅极线 D1上、 位于第 3行第 1列的 TFT, 与连接在第 2条栅极线 D2上、 第 7行第 1列的 TFT连接在 S3上； 连接在第 1条栅极线 D1上、 位于第 4行第 1列的 TFT, 与连接在第 2条栅极线 D2上、 位于第 8 行第 1列的 TFT连接在 S4上， 依次类推。
在驱动方面 , 栅极驱动集成电路按扫描顺序逐条驱动各栅极线 , 从而同 时驱动与一条栅极线连接的 4行 TFT的栅极开通，在 4行 TFT的栅极开通时， 源极驱动集成电路驱动各源极线输出相应的驱动信号， 以实现像素翻转。
具体地， 当栅极驱动集成电路驱动栅极线 D1时，像素阵列上编号为 Gl、 G2、 G3、 G4的 TFT同时开通， 同时源极驱动集成电路上输出对应像素的数 据； 当栅极驱动集成电路驱动栅极线 Di开启时， 像素阵列上编号为
G[4(i-1)+1]、 G[4(i-l)+2]、 G[4(i-l)+3]、 G[4(i-l)+4] 的 TFT同时开通， K i < ( TFT的行数除以 4得到的整数）。
源极驱动集成电路驱动各源极线输出相应的驱动信号实现像素翻转的方 式如图 6和图 7所示， 该翻转方式的核心思想是对于同一帧画面， 每相邻两 个 TFT连接的源极线输出的驱动信号极性相反； 对于相邻的两帧画面， 同一 TFT连接的源极线输出的驱动信号极性相反。
对应图 5所示的像素阵列， 具体地， 第 Y帧画面下源极驱动集成电路的 同一条源极线上输出的驱动信号电压极性相同， 第 4(k-l)+l、 4(k-l)+2、 4(k-l)+3、 4(k-l)+4条源极线上每相邻两条源极线上的极性相反， l k （源 极线总数除以 4得到的整数）， Y+1帧画面下源极驱动集成电路的同一条源极 线上输出的驱动信号电压极性与 Y帧时相反，第 4(k-l)+l、4(k-l)+2、4(k-l)+3、 4(k-l)+4条源极线上每相邻两条源极线上的极性相反。 从而达到既能防止液 晶老化又能降低功耗的目的， 其中 Y为大于等于 1的整数。
实施例 2
本实施例除了将实施例 1中的白色像素换为黄色像素其他不变， 从而弥 补黄色和蓝绿色的表现力不足， 可以更加生动地再现黄色、 金色、 蓝绿色等 传统三原色技术难以表现的色彩， 拉伸了蓝色的表现色域， 提高了蓝色、 绿 色和黄色的表现力， 更能够有效的使用黄色波长， 实现更广阔的色域。
实施例 3
本实施例中显示面板由一个以阵列分布的多个 TFT的显示面板、 一个驱 动 TFT源极的带有源极线的源极驱动集成电路、一个驱动 TFT栅极的带有栅 极线的栅极驱动集成电路以及背光模块组成。 显示面板上的像素阵列像素阵 列分布示意图如图 8所示， 每个像素由 RGBW四种子像素组成， 每个像素的 四种子像素 RGBW呈矩形分布。
栅极驱动集成电路的每条栅极线连接相邻 4行 TFT的栅极， 且不同栅极 线连接不同行的 TFT的栅极；连接在同一条栅极线上的不同 TFT的源极分别 与不同的源极线连接，且连接在不同栅极线上位于同一列并间隔 g*4-l个 TFT 的 TFT的源极连接在同一条源极线上， g为正整数。 如连接在第 1条栅极线 D1上、 位于第 1行第 1列的 TFT, 与连接在第 2条栅极线 D2上、 位于第 5 行第 1列的 TFT连接在 S1上； 连接在第 1条栅极线 D1上、 位于第 2行第 1 列的 TFT, 与连接在第 2条栅极线 D2上、 位于第 6行第 1列的 TFT连接在 S2上； 连接在第 1条栅极线 D1上、 位于第 3行第 1列的 TFT, 与连接在第 2条栅极线 D2上、 第 7行第 1列的 TFT连接在 S3上； 连接在第 1条栅极线 D1上、 位于第 4行第 1列的 TFT, 与连接在第 2条栅极线 D2上、 位于第 8 行第 1列的 TFT连接在 S4上， 依次类推。
在驱动方面 , 栅极驱动集成电路按扫描顺序逐条驱动各栅极线 , 从而同 时驱动与栅极线连接的 4行 TFT的栅极开通， 在 4行 TFT的栅极开通时， 源 极驱动集成电路驱动各源极线输出相应的驱动信号， 以实现像素翻转。
具体地， 当栅极驱动集成电路驱动栅极线 D1时，像素阵列上编号为 Gl、 G2、 G3、 G4的 TFT同时开通， 同时源极驱动集成电路上输出对应像素的数 据； 当栅极驱动集成电路驱动栅极线 Di开启时， 像素阵列上编号为
G[4(i-1)+1]、 G[4(i-l)+2]、 G[4(i-l)+3]、 G[4(i-l)+4] 的 TFT同时开通， K i < ( TFT的行数除以 4得到的整数）。
源极驱动集成电路驱动各源极线输出相应的驱动信号实现像素翻转的方 式如图 9所示， 该翻转方式的核心思想是对于同一帧画面， 每相邻两个 TFT 连接的源极线输出的驱动信号极性相反； 对于相邻的两帧画面， 同一 TFT连 接的源极线输出的驱动信号极性相反。
对应图 8所示的像素阵列， 具体地， 第 Y帧画面下源极驱动集成电路的 同一条源极线上输出的驱动信号电压极性相同， 第 4(k-l)+l、 4(k-l)+2、
4(k-l)+3、 4(k-l)+4条源极线上每相邻两条源极线上的极性相反， l k （源 极线总数除以 4得到的整数）， Y+1帧画面下源极驱动集成电路的同一条源极 线上输出的驱动信号电压极性与 Y帧时相反，第 4(k-l)+l、4(k-l)+2、4(k-l)+3、 4(k-l)+4条源极线上每相邻两条源极线上的极性相反。 从而达到既能防止液 晶老化又能降低功耗的目的， 其中 Y为大于等于 1的整数。
本实施例与实施例 1的不同之处在于 TFT对应的子像素的分布方式不 同， 对于实施例 1来说， 对于分辨率为 m*n ( m代表列， n代表行） 的显示 面板， 实施例 1需要的栅极驱动集成电路数据线为 n/4, 源极驱动集成电路数 据线为 16m, 本实施例需要的栅极驱动集成电路数据线为 n/2, 源极驱动集成 电路数据线为 8m。 实施例 4
本实施例除了将实施例 3中的白色像素换为黄色像素其他不变， 从而弥 补黄色和蓝绿色的表现力不足， 可以更加生动地再现黄色、 金色、 蓝色等传 统三原色技术难以表现的色彩， 拉伸了蓝色的表现色域， 提高了蓝色、 绿色 和黄色的表现力， 更能够有效的使用黄色波长， 实现更广阔的色域。
本发明上述实施例，在同一时间内，多行栅极同时开启，保证了每个 TFT 上栅极的开启时间。相对于具有相同分辨率的传统 RGB三色液晶屏来说， 增 加了数据线的数量， 但栅极扫描线的数量减小为原来的 1/4或 1/2, 保证了栅 极的开启时间， 可以有效地提高画面的品质。 同时， 增加的像素可以用来提 高背光的利用率、 降低功耗或者扩大色域。 翻转方式上釆用源极驱动集成电 路侧的列翻转 ( column inversion ), 以实现面板侧像素点翻转的效果， 从而在 保证画面品质的同时降低了功耗。 发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内， 则本发明也意图包含这些改动和变型在内。
