本发明涉及显示技术领域, 尤其涉及一种阵列基板及其驱动方法、 显示装置。 背景技术
液晶显示器 (Liquid Crystal Display, 筒称 LCD ) 因其所具有的功 耗低、 外形轻薄以及无辐射等特点而倍受工程师青睐, 因此已被广泛地 应用于包括电脑、 手机等电子产品在内的各种电子设备中。 液晶显示器 通常包括阵列基板、 彩膜基板以及位于阵列基板和彩膜基板之间的液晶 层, 其显示原理主要是: 通过改变液晶层两端的电位差, 即可改变液晶 层内液晶分子的旋转角度, 使得液晶的光透性发生改变, 以显示出不同 的图像。
一般而言, 施加在液晶层两端的电压极性必须每隔一预定时间进行 反转, 以避免液晶材料产生极化而造成永久性的破坏。 常见的像素阵列 极性反转的方式有帧反转、 列反转、 行反转和点反转四种。 其中, 在上 一帧写入结束、 下一帧写入开始之前, 如果在整帧上的像素所储存的电 压极性 Δ ν (定义 =像素电压 Vpixel-公共电压 Vc。m)都是相同的 (全部 是正或全部是负 ) , 即称为帧反转; 若是同一列上的像素所储存的电压 极性都是相同的, 且相邻列上的像素所储存的电压极性相反, 即称为列 反转; 若是同一行上的像素所储存的电压极性都是相同的, 且相邻行上 的像素所储存的电压极性相反, 即称为行反转; 若是每个像素所储存的 电压极性, 都与其上下左右相邻的像素所储存的电压极性相反, 即称为 点反转。 为了提高整个显示画面的品质, 像素点反转驱动方式已逐渐成 为目前主流的驱动方式。
在现有的点反转驱动方式下, 数据线信号需要在每行栅线的扫描时 间内反转一次, 以实现如图 1所示的点反转驱动,其时序图如图 2所示, 其中定义每一像素单元显示某灰阶需要 Δ ν=2ν,每个像素单元的公共电 极电压 Vc。m=3V , 由于栅线 G1 和数据线所界定的像素单元极性为正 (Vpixel-Vc。m=2) , 则数据线 D1 电压为 5V, 栅线 G2和数据线 D1所界定
的像素区域极性为负(Vpixel-Vc。m=-2), 则数据线电压为 IV。 以此类推, 数据线 D1电压需要在 IV与 5V之间不断来回反转, 数据线 D2与数据 线 D1极性相反, 由于公共电极电压 Ve。m=3V, 故数据线 D2电压也需要 在 IV与 5V之间不断来回反转, 采用这样一种点反转驱动方式, 由于数 据线驱动电压在正负极性灰阶之间的电压摆幅相当大, 因而在正负极性 灰阶电压的切换过程中会带来很大的功耗。 发明内容

下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案 进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实 施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术 人员所获得的所有其他实施例, 都属于本发明保护的范围。
本发明实施例提供的阵列基板, 如图 3所示, 包括由横纵交叉的多 条栅线 31和多条数据线 32划分成的呈矩阵状排列的多个像素单元 33 , 每个像素单元 33又包括像素电极 331 , 其中, 每个像素单元 33还包括 公共电极 332。
在像素单元 33 矩阵中, 行列数之和 (即, 行数和列数之和) 相同 的像素单元 33对应的公共电极 332的电压极性相同。
相邻像素单元 33的公共电极 332的电压极性相反。
例如, 在如图 3所示的像素单元 33矩阵中, 第 2行第 1列像素单 元的行列数之和与第 1行第 2列像素单元的行列数之和相等, 第 3行第 1列、 第 2行第 2列以及第 1行第 3列像素单元的行列数之和相等, 以 此类推。 由于行列数之和相等的像素单元呈一条斜线排列, 因此可以将 每一组斜向排列的像素单元所对应的公共电极相连接, 形成斜向排列的 多组公共电极条, 多组公共电极条相互平行。 其中, 可以将行列数之和 公共电极条, 将行列数之和均为 2n 的像素单元所对应的公共电极组成 的公共电极条称为偶数行公共电极条, 其中 n为自然数。
采用这样一种结构的阵列基板, 通过控制输入像素电极 331和公共 电极 332的电压可以实现点反转驱动。 进一步地, 在一帧画面显示结束 时, 每个公共电极 332的电压极性还将反转一次, 从而可以提高电压反 转的频率, 进一步避免液晶材料发生极化, 提高了显示装置的质量。
本发明实施例提供的阵列基板, 包括由横纵交叉的多条栅线和多条 数据线划分成的呈矩阵状排列的多个像素单元, 每个像素单元包括像素 电极, 每个像素单元还包括公共电极; 在像素单元矩阵中, 行列数之和 相同的像素单元对应的公共电极的电压极性相同; 相邻像素单元的公共 电极的电压极性相反。 采用这样一种结构的阵列基板, 在实现了点反转 驱动的同时, 大大降低了数据线驱动电压在正负极性灰阶之间的电压摆 幅, 从而有效降低了点反转驱动模式下阵列基板的功耗。
需要说明的是, 在本发明实施例中, 一个像素单元的相邻像素单元 具体是指在呈矩阵形式排列的像素单元阵列中与该像素单元上下左右 方向相邻的像素单元, 即对于一个像素单元来说, 最多可以有四个相邻 的像素单元。
进一步地, 在如图 3所示的阵列基板中, 该阵列基板还包括驱动电 路 34 , 该驱动电路 34与公共电极 332电连接, 用于控制每个公共电极 332的电压。
该驱动电路 34可以包括第一输出端 341和第二输出端 342。该第一 输出端 341连接奇数行公共电极条, 第二输出端 342连接偶数行公共电 极条, 该第一输出端 341与第二输出端 342输出电压的极性相反。
在本发明实施例中, 奇数行公共电极条均可以采用相同电压, 同样
偶数行公共电极条也可以采用相同电压, 因此可以将所有的奇数行公共 电极条采用一体结构制成, 将所有的偶数行公共电极条也采用一体结构 制成, 这样一来, 可以大大降低阵列基板的制作难度。
进一步地, 第一输出端 341和第二输出端 342均可以采用栅线金属 层制成。 其中, 栅线金属层主要用于形成栅线的图案, 在本发明实施例 中, 可以通过对栅线金属层进行一次构图工艺同时形成栅线以及第一输 出端 341和第二输出端 342的图案,这样可以筒化阵列基板的层级结构, 降低产品的生产难度。
具体的, 驱动电路 34可以采用驱动芯片 IC, 在图 3所示的阵列基 板中, 条状的公共电极 332在面板周边通过穿过栅绝缘层和钝化层 (图 3 中未示出) 的过孔与最底层的栅线金属层连接, 栅线金属层最终连接 到驱动芯片 IC的引脚上, 以便驱动芯片 IC内部的信号能加载到公共电 极 332上, 这样将斜向的公共电极 332串联在一起, 有利于降低点反转 模式下的驱动功耗。 这里需要特别说明的是, 左右相邻像素以及上下相 邻像素之间的公共电极 332 虽然不是全部连接在一起, 但是在栅线 31 和数据线 32 两边均会有一定宽度的黑矩阵 (在彩膜基板上制作) , 因 此并不会产生漏光的现象。
本发明实施例提供的阵列基板可以适用于 FFS ( Fringe Field Switching , 边缘场开关 ) 型、 AD-SDS ( Advanced-Super Dimensional Switching, 筒称为 ADS , 高级超维场开关)型以及 IPS ( In Plane Switch, 横向电场效应) 型等像素电极与公共电极均设置于阵列基板上的一类液 晶显示装置的生产。
在如图 3所示的阵列基板中, 是以 FFS型的液晶显示装置为例进行 的说明。 该像素电极 331通过 TFT ( Thin Film Transistor , 薄膜晶体管) 分别与栅线 31和数据线 32相连接。
其中, TFT区域的剖面图可以如图 4所示, 包括形成在基板 40上 的 TFT的栅极 41 , 其上形成栅绝缘层 42 , 有源层 43形成在栅绝缘层 42上并位于栅极层 41的上方, TFT的源极 441的一端位于栅极 41的上 方, 另一端与数据线 (图 4中未示出) 连接, 漏极 442的一端位于栅极 41的上方, 另一端与像素电极 331连接, 源极 441与漏极 442之间形成 TFT沟道区域 45。 钝化层 46形成在上述结构图形上, 条状排列的公共
电极 332形成在钝化层 46上, 工作时, 像素区域内的奇数行公共电极 条中的公共电极 332采用相同的电压且偶数行公共电极条中的公共电极 332 采用相同的电压, 并且奇数行公共电极条和偶数行公共电极条的电 压极性相反, 相邻像素区域内的像素电极 331采用相反的电压, 通过像 素电极 331与公共电极 332之间的边缘电场驱动液晶分子的偏转, 从而 实现黑白和灰度的显示。
需要说明的是, 在 FFS型显示装置的阵列基板中, 公共电极和像素 电极可以异层设置, 其中位于上层的电极包含多个条形电极, 位于下层 的电极可以为平板形或同样采用条形电极, 本发明对此并不做限制。 其 中, 异层设置是针对至少两种图案而言的, 至少两种图案异层设置是指: 分别将至少两层薄膜通过构图工艺形成至少两种图案。 对于两种图案异 层设置是指: 通过构图工艺, 由两层薄膜各形成一种图案。 例如, 公共 电极和像素电极异层设置是指: 由第一层透明导电薄膜通过构图工艺形 成下层电极, 由第二层透明导电薄膜通过构图工艺形成上层电极, 其中, 下层电极为公共电极 (或像素电极) , 上层电极为像素电极 (或公共电 极) 。 应当理解, 以上也仅是对本发明实施例所做的举例说明, 而并非 对本发明所做的限制。
采用本发明实施例所提供的这样一种阵列基板, 可以在实现点反转 驱动方式的同时有效降低阵列基板的功耗。
为了更好地理解上述原理, 以下参照图 5所示的像素单元示意图对 本发明实施例提供的阵列基板驱动方式进行举例说明。 定义显示某灰阶 需要像素电极和公共电极之间具有 2V 的电压差, 正极性像素的公共电 极电压为 -3V, 负极性像素的公共电极为 3V, 即图 5中斜虚线 A贯穿的 像素的公共电极的电压为 -3V, 斜实线 B 贯穿的像素的公共电极的电压 为 3V。
如图 5所示,由于栅线 G1和数据线 D1所界定的像素区域极性为正 (Vpixei-Vcom =2) ,公共电极电压 Vc。m为 -3 V ,则数据线电压为 2+( -3 )=- 1 V。 栅线 G2和数据线 D1所界定的像素区域极性为负(Vpixel-Vc。m =-2) , 公共 电极电压 。01为 3 , 则数据线电压为 -2+3=lV。 同理可知栅线 G3与数 据线 D1 所界定的像素区域极性为正, 公共电极电压 ^ 为^ , 则数 据线电压为 -1V。 依此规律, 数据线 Dl , D3 , D5……的电压在 -IV与 IV
之间不断来回翻转, 反转的频率为每扫描一行栅线反转一次。 栅线 G1和数据线 D2所界定的像素区域极性为负(Vpixel-Vc。m =-2), 公共电极电压 Vc。m为 3V, 则数据线电压为 -2+3=lV。 栅线 G2和数据线 D2 所界定的像素区域极性为正 (Vpixel-Vc。m =2) , 公共电极电压 U -3V, 则数据线电压为 2+ ( -3 ) =-lV。依次规律,数据线 D2, D4, D6 ··· ··· 的电压同样在 -IV与 IV之间不断来回翻转, 反转的频率为每扫描一行 栅线反转一次。
综上所述, 这种设计结构在点反转驱动方式下, 对于需要像素电极 和公共电极之间具有 2V 的电压差以显示某灰阶的情况而言, 所有数据 线 Dl , D2, D3……的电压均在 -IV与 IV之间不断来回反转, 反转的频 率为每扫描一行栅线反转一次。 相比传统奇偶行(列)公共电极均为 3V, 数据线需要在 IV与 5V之间不断来回反转, 明显可以节省功耗。
这里需要特别说明的是: 为使帧与帧之间像素的极性亦反转, 如图 6所示, 斜虚线 A的公共电极与斜虚线 B的公共电极的电压极性在每帧 画面结束后反转一次。 这种设计不但可以实现点反转的驱动模式, 而且 还可以节省数据线上的电压输出从而节省整个面板的驱动功耗。
采用这样一种结构的阵列基板, 在实现了点反转驱动的同时, 大大 降低了数据线驱动电压在正负极性灰阶之间的电压摆幅, 从而有效降低 了点反转驱动模式下阵列基板的功耗。
本发明实施例还提供了一种显示装置, 包括如上所述的阵列基板。 在本发明实施例中, 显示装置具体可以包括液晶显示装置, 例如该 显示装置可以为液晶显示器、 液晶电视、 数码相框、 手机或平板电脑等 任何具有显示功能的产品或者部件。
需要说明的是, 阵列基板可以适用于 FFS ( Fringe Field Switching , 边缘场开关) 型、 AD-SDS ( Advanced-Super Dimensional Switching, 筒 称为 ADS , 高级超维场开关)型以及 IPS ( In Plane Switch, 横向电场效 应) 型等像素电极与公共电极均设置于阵列基板上的一类液晶显示装置 的生产。
其中, 阵列基板的详细结构已在前述实施例中做了详细的描述, 此 处不再赘述。
本发明实施例提供的显示装置, 包括阵列基板, 该阵列基板又包括
由横纵交叉的多条栅线和多条数据线划分成的呈矩阵状排列的多个像 素单元, 每个像素单元包括像素电极, 每个像素单元还包括公共电极; 在像素单元矩阵中, 行列数之和相同的像素单元对应的公共电极的电压 极性相同; 相邻像素单元的公共电极的电压极性相反。 采用这样一种结 构的阵列基板, 在实现了点反转驱动的同时, 大大降低了数据线驱动电 压在正负极性灰阶之间的电压摆幅, 从而有效降低了点反转驱动模式下 阵列基板的功耗。
本发明实施例还提供了一种阵列基板驱动方法, 该阵列基板包括由 横纵交叉的多条栅线和多条数据线划分成的呈矩阵状排列的多个像素 单元, 每个像素单元包括像素电极, 每个像素单元还包括公共电极, 如 图 7所示, 该方法包括:
5701、 在进行第一帧画面显示时, 向在像素单元矩阵中行列数之和 为 2n- l的像素单元对应的公共电极输入第一电压。
5702、 向在像素单元矩阵中行列数之和为 2n 的像素单元对应的公 共电极输入第二电压, 该第一电压和第二电压极性相反。
其中, n为自然数。
需要说明的是, 在进行第一帧画面显示时, 步骤 S701和步骤 S702 并无严格的先后顺序, 二者的执行顺序可以相互倒换。
例如, 在如图 3所示的像素单元 33矩阵中, 第 2行第 1列像素单 元的行列数之和与第 1行第 2列像素单元的行列数之和相等, 第 3行第 1列、 第 2行第 2列以及第 1行第 3列像素单元的行列数之和相等, 以 此类推。 由于行列数之和相等的像素单元呈一条斜线排列, 因此可以将 每一组斜向排列的像素单元所对应的公共电极相连接, 形成斜向排列的 多组公共电极条, 多组公共电极条相互平行。 其中, 可以将行列数之和 公共电极条, 将行列数之和均为 2n 的像素单元所对应的公共电极组成 的公共电极条称为偶数行公共电极条, 其中 n为自然数。
本发明实施例提供的阵列基板及其驱动方法、 显示装置, 该阵列基 板包括由横纵交叉的多条栅线和多条数据线划分成的呈矩阵状排列的 多个像素单元, 每个像素单元包括像素电极, 每个像素单元还包括公共 电极; 在像素单元矩阵中, 行列数之和相同的像素单元对应的公共电极
的电压极性相同; 相邻像素单元的公共电极的电压极性相反。 采用这样 一种结构的阵列基板, 在实现了点反转驱动的同时, 大大降低了数据线 驱动电压在正负极性灰阶之间的电压摆幅, 从而有效降低了点反转驱动 模式下阵列基板的功耗。
进一步地, 如图 7所示, 所述方法还包括:
S703、 在进行第二帧画面显示时, 向第一帧画面显示时电压为第一 电压的公共电极输入第二电压, 向第一帧画面显示时电压为第二电压的 公共电极输入第一电压。
采用这样一种结构的阵列基板, 通过控制输入像素电极和公共电极 的电压可以实现点反转驱动。 进一步地, 在一帧画面显示结束时, 每个 公共电极的电压极性还将反转一次, 从而可以提高电压反转的频率, 进 一步避免液晶材料发生极化, 提高了显示装置的质量。
本发明实施例提供的阵列基板可以适用于 FFS ( Fringe Field Switching , 边缘场开关 ) 型、 AD-SDS ( Advanced-Super Dimensional Switching, 筒称为 ADS , 高级超维场开关)型以及 IPS ( In Plane Switch, 横向电场效应) 型等像素电极与公共电极均设置于阵列基板上的一类液 晶显示装置的生产。
在本发明实施例中, 是以 FFS型的液晶显示装置为例进行的说明。 该像素电极通过 TFT ( Thin Film Transistor, 薄膜晶体管 )分别与栅线和 数据线相连接。 这样一种 FFS结构的阵列基板通过同一平面内像素电极 场形成多维电场, 使液晶盒内像素电极间、 电极正上方所有取向液晶分 子都能够产生旋转, 从而提高了平面取向型液晶工作效率并增大了透光 效率。
本领域普通技术人员可以理解: 实现上述方法实施例的全部或部分 步骤可以通过程序指令相关的硬件来完成, 前述的程序可以存储于一计 算机可读取存储介质中, 该程序在执行时, 执行包括上述方法实施例的 步骤; 而前述的存储介质包括: ROM、 RAM, 磁碟或者光盘等各种可以 存储程序代码的介质。
以上所述, 仅为本发明的具体实施方式, 但本发明的保护范围并不 局限于此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范围
内, 可轻易想到变化或替换, 都应涵盖在本发明的保护范围之内。 因此, 本发明的保护范围应以权利要求的保护范围为准。
