Description

一种阵列基板及显示面板
【技术领域】
本发明涉及显示技术领域, 特别涉及一种阵列基板及显示面板。 【背景技术】
液晶显示器中使用的薄膜晶体管通常有非晶硅薄膜晶体管和多晶硅薄膜 晶体管, 其中, 非晶硅薄膜晶体管随着使用时间的增加, 其迁移率低, 光敏退 化性严重; 而 LTPS ( Low Temperature Poly-silicon, 低温多晶硅技术)则具有较 高的迁移率和稳定性。
本申请的发明人在长期的研发中发现, 目前 LTPS 面板进行 GOA ( Gate Driver on Array, 阵列基板栅极驱动)设计时, 通常采用单向驱动的隔行扫描模 式, 即左右两侧都设有 GOA, 按照扫描线扫描的时序进行间隔开启。 由于扫描 线上存在电阻 -电容延迟, 扫描线起始端与末端的信号就会存在差异, 直接影响 到扫描线起始端与末端的像素单元的像素电压。 面板越大, 扫描线越长, 电阻- 电容延迟就会越严重, 扫描线两端的像素单元的像素电压差异就会越明显, 导 致面板两侧的亮度大于中间的亮度, 出现显示不均。
【发明内容】

为解决上述技术问题, 本发明釆用的另一个技术方案是提供一种显示面板, 包括如上述的阵列基板。
本发明通过在远离扫描信号输入端的第二区域的每个像素单元设置控制单 元, 减小第二区域的像素单元的像素电压, 以使多个像素单元的像素电压一致, 解决面板左右两侧泛白的问题, 使显示面板的显示效果更均匀, 显示画面质量 更高。

【具体实施方式】
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。
本发明提供第一实施例的阵列基板。请参见图 1, 本实施例所揭示的阵列基 板包括:
多条扫描线 Gn, 本实施例以扫描线 G1至 G5为例进行说明;
多条数据线 Dn, 本实施例以数据线 D1至 D10为例进行说明, 与多条扫描 线 Gn相交设置, 以形成多个像素单元 10;
其中, 将多个像素单元 10沿着扫描线 Gn的方向划分为第一区域 A和第二 区域 B, 第一区域 A靠近扫描信号输入端, 第二区域 B远离所述扫描信号输入 端。第二区域 B的每个像素单元 101包括第一薄膜晶体管 T1和与第一薄膜晶体 管 T1连接的控制单元 1011 , 控制单元 1011用于减小第一薄膜晶体管所在像素 单元 101的像素电压;第一区域 A的每个像素单元 102包括第二薄膜晶体管 T2。
具体的, 阵列基板在两侧 GOA驱动电路(图中未示出)的驱动下进行隔行 扫描, 即右侧的 GOA驱动电路向奇数行扫描线输入扫描信号, 左侧的 GOA驱 动电路向偶数行扫描线输入扫描信号, 且奇数行和偶数行的扫描信号依次交替 输入。
可选的, 也可以通过右侧的 GOA驱动电路向偶数行扫描线输入扫描信号, 通过左侧的 GOA电路向奇数行扫描线输入扫描信号。
其中, 第一区域 Α和第二区域 Β可以以中间线, 即每条扫描线 Gn的中点 连线划分, 例如当前行扫描信号从右侧输入, 右半侧的多个像素单元 10为第一 区域 A, 左半侧的多个像素单元 10为第二区域 B; 也可以以当前行的泛白区域 划分, 例如当前行扫描信号从右侧输入, 将当前行中左侧边缘泛白的区域划分 为第二区域 B,将当前行中右侧边缘,即当前行无泛白的区域划分为第一区域 A; 还可以以不同行的泛白区域划分, 例如当前扫描信号从右侧输入, 将当前行中 左侧边缘泛白的区域划分为第二区域 B,将对应下一行泛白的区域划分为第一区 域 A。
参见图 1至图 4, 在第二区域 B的像素单元 101中, 控制单元 1011包括第 三薄膜晶体管 T3和第一电容 C1 , 第三薄膜晶体管 T1的漏极连接第三薄膜晶体 管 T3所在的像素单元 101的像素电极, 第三薄膜晶体管 T3的栅极连接下一行 扫描线 G2, 第三薄膜晶体管 T3的源极通过第一电容 C1接地, 其中, 第一电容 C1由第一薄膜晶体管 T1的源极与公共电极等效构成。 第二区域 B的像素单元 101还包括第一液晶电容 C2以及第一存储电容 C3, 第一薄膜晶体管 T1的源极 与数据线 m连接, 第一薄膜晶体管 Ti的栅极与当前的扫描线 Gi连接, 第一 薄膜晶体管 Ti的漏极连接第一薄膜晶体管 T1所在像素单元 101的像素电极, 其中, 第一液晶电容 C2由第一薄膜晶体管 T1所在像素单元 101的像素电极和 彩膜基板(图中未示出)上的公共电极等效构成, 第一存储电容 C3由第一薄膜 晶体管 T1所在像素单元 101的像素电极与阵列基板上的其他金属线等效构成。
其中, 第三薄膜晶体管 T3的漏极连接在第一液晶电容 C2的一端和第一存 储电容 C3的一端之间。
在当前的扫描线 G1输入扫描信号 Vgl, 即扫描线 G1在右侧输入扫描信号, 此时第二区域 B的像素单元 101中, 当前行的第三薄膜晶体管 T3断开, 当前行 的第一薄膜晶体管 T1导通, 当前行的第二薄膜晶体管 T2导通; 下一行扫描线 G2的输入端与当前扫描线 G1的输入端相反,即扫描线 G2在左侧输入扫描信号, 且下一行扫描线 G2上的第二区域 B的像素单元 101与当前扫描线 G1上的第二 区域 B的像素单元 101位于不同的数据线上;在当前行的下一行扫描线 G2输入 扫描信号 Vg2 , 此时第二区域 B的像素单元 101中, 第三薄膜晶体管 T3导通, 当前行的第一薄膜晶体管 T1断开, 当前行的第二薄膜晶体管 T2断开, 当前行 的第三薄膜晶体管 T3用于将当前行的像素电压拉低。
具体的, 当前的扫描线 G1输入扫描信号 Vgl时, 第三薄膜晶体管 T3断开, 第一薄膜晶体管 T1导通, 第二薄膜晶体管 T2导通, 数据线 D1输入电压, 此 时第二区域 B的像素单元 101中的第一薄膜晶体管 T1源极电压为 Vdl, 栅极电 压为 Vgir , 像素电压 (即漏极电压) 为\^11'; 第一区域 A中的像素单元 102中 的薄膜晶体管 T2源极电压为 Vd2, 栅极电压为 Vgl l , 像素电压 (即漏极电压) 为 11;然后当前扫描线 G1上的扫描信号 Vgl断开,使第一薄膜晶体管 T1断开, 此时第二区域 B的像素单元 101中的第一薄膜晶体管 1源极电压为 Vdl, 栅极电 压为 V 12' ,像素电压为 V 12' ; 第一区域 A中的像素单元 102中的薄膜晶体管 T2 源极电压为 Vd2 , 栅极电压为 Vg12, 像素电压 (即漏极电压) 为^12; 由于第二 区域 B的像素单元 101内的元件会在高频下产生电容联系,即产生寄生电容 Cgs, 根据电荷不减定律, 馈通( feed through ) AV=(Vgl l-Vg12)*Cgs / (Cgs+C2+C3) ; 同时馈通电压 AV=Vd - Vs12, 所以 Vs12 = Vd -(Vgl l-Vg12)*Cgs / (Cgs+C2+C3)。
具体的, 第一区域 A中的像素单元 102靠近扫描信号 Vgl, 当第一薄月 晶体 管 T1和第二薄膜晶体管 T2断开, ^在很短的时间内下降, 使得 Vgl l与 Vg12的 差值较大, 即馈通电压 AV较大, 对应像素电压 Vs12较小, 显示亮度正常; 第二 区域 B的像素单元 101远离扫描信号 Vgl, 当第一薄膜晶体管 T1和第二薄膜晶 体管 T2断开, 第二区域 B的像素单元 101产生电阻电容延迟, Vg'下降延緩, 使得 Vgl l'与 Vg12'的差值较小, 即馈通电压 AV'较小, 对应像素电压 Vs12'较大, 显示亮度较高, 在屏幕上出现亮点。 当下一行扫描线 G2输入扫描信号 Vg2 , 第 三薄膜晶体管 T3导通,根据电荷共享原理, 将第二区域 B的像素单元 101的像 素电压 Vs12'拉低, 并且被拉低后的第二区域 B的像素单元 101的像素电压 (图 中未示出) 与第一区域 A.的像素单元 102的像素电压 Vs12的值相等。 由于当前 扫描线 G1上的扫描信号 与下一行扫描线 G2的扫描信号 VK2输入的时间间隔 较短, 人眼无法分辨, 用户能够看到的是经过第三薄膜晶体管 T3作用后第二区 域 B的像素单元 101 , 因此第二区域 B的像素单元 101的显示亮度与第一区域 A的像素单元 102的显示亮度相同。 类似的, 多行扫描线依次扫描, 在第二区 域 B的像素单元 101中的第三薄膜晶体管 T3的作用下,拉低靠近扫描信号输入 端的第二区域 B的像素单元 101中的像素电压,使得第二区域 B的像素单元 101 中的像素电压与第一区域 A的像素单元 102中的像素电压相等, 两侧显示亮度 相同。
本发明实施例通过在远离扫描信号输入端的第二区域的每个像素单元设置 控制单元, 减小第二区域的像素单元的像素电压, 以使多个像素单元的像素电 压一致, 解决面板左右两侧泛白的问题, 使显示面板的显示效果更均匀, 显示 画面质量更高。
本发明进一步提供第二实施例的阵列基板。 请参见图 5和图 6, 本实施例所 揭示的阵列基板包括: 106959 多条扫描线 Gn, 本实施例以扫描线 G1至 G5为例进 4亍说明;
多条数据线 Dn, 本实施例以数据线 D1至 D10为例进行说明, 与多条扫描 线 Gn相交设置, 以形成多个像素单元 10;
其中, 将多个像素单元 10沿着扫描线 Gn的方向划分为第一区域 A和第二 区域 B, 第一区域 A靠近扫描信号输入端, 第二区域 B远离所述扫描信号输入 端。第二区域 B的每个像素单元 101包括第一薄膜晶体管 T1和与第一薄膜晶体 管 T1连接的控制单元 1011,控制单元 1011用于减小第一薄膜晶体管 T1所在像 素单元 101 的像素电压; 第一区域 A的每个像素单元包括第二薄膜晶体管 T2 和第四薄膜晶体管 Τ4。
具体的, 第一区域 Α的每个像素单元还包括第二液晶电容 C4、 第二存储电 容 C5、 第二电容 C6和第三电容 C7, 第二薄膜晶体管 T2的源极与数据线 D6 连接, 第二薄膜晶体管 T2的栅极与当前的扫描线 G1连接, 第二薄膜晶体管 T2 的漏极连接第二薄膜晶体管 T2所在的像素单元 102的像素电极, 其中, 第二液 晶电容 C4由第二薄膜晶体管 T2所在像素单元 102的像素电极和彩膜基板 (图 中未示出) 上的公共电极等效构成, 第二存储电容 C5由第二薄膜晶体管 T2所 在像素单元 102 的像素电极与阵列基板上的其他金属线等效构成。 第四薄膜晶 体管 T4的栅极连接下一行扫描线, 第四薄膜晶体管 T4的源极通过第二电容 C6 接地, 第四薄膜晶体管 T4的漏极通过第三电容 C7接地, 其中, 第二电容 C6 由第四薄膜晶体管 T4的源极与公共电极等效构成, 第三电容 C7由第四薄膜晶 体管 T4的漏极与公共电极等效构成。 由于制备阵列基板时并不确定当前扫描线 的输入方向, 所以在第一区域 A的像素单元 102中设置第四薄膜晶体管 T4, 以 根据扫描线的输入方向调整控制单元 1011和第四薄膜晶体管 Τ4的连接, 同时 保证了液晶面板的一致性。
本发明实施例通过在远离扫描信号输入端的第二区域的每个像素单元设置 控制单元, 在靠近扫描信号输入端的第一区域的每个像素单元设置薄膜晶体管, 减小第二区域的的像素电压, 以使多个像素单元的像素电压一致, 保持面板的 一致性, 解决面板左右两侧泛白的问题, 使显示面板的显示效果更均匀, 显示 画面质量更高。
本发明进一步提供一实施例的显示面板, 请参见图 7, 本发明显示面板实施 例包括:
第一基板 701、第二基板 702和位于第一基板 701和第二基板 702之间的液 晶层 703 , 其中第一基板 701为阵列基板, 该阵列基板为上述实施例所揭示的阵 列基板, 在此不再赘述。
本发明实施例通过在远离扫描信号输入端的第二区域的每个像素单元设置 控制单元, 减小第二区域的像素单元的像素电压, 以使多个像素单元的像素电 压一致, 解决面板左右两侧泛白的问题, 使显示面板的显示效果更均匀, 显示 画面质量更高。
以上所述仅为本发明的实施方式, 并非因此限制本发明的专利范围, 凡是 利用本发明说明书及附图内容所作的等效结构或等效流程变换, 或直接或间接 运用在其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
