Description

显示装置的驱动方法和驱动装置
技术领域
[0001] 本申请实施例属于显示技术领域, 尤其涉及一种显示装置的驱动方法和驱动装 置。
背景技术
[0002] 随着显示技术的不断发展, 液晶面板、 显示器等显示设备不断向着轻薄化、 大 屏化、 低功耗、 低成本的方向发展。 目前常用的显示面板的驱动方式有基于三 栅极晶体管 (Tri-Gate, 3D三维晶体管) 技术的三栅极驱动方式和基于双栅极 ( Dual Gate) 驱动技术的双栅极驱动方式。 不论采用哪种驱动方式对子像素进行 行扫描驱动, 都是通过从扫描线的起始端输入扫描驱动信号传递到扫描线的末 端, 对扫描线上连接的各个子像素进行逐个充电。
[0003] 然而, 由于扫描线与数据线之间、 相邻扫描线之间、 扫描线与晶体管之间或者 扫描线与子像素之间存在寄生电容, 该寄生电容构成扫描线上的驱动负载, 使 得扫描驱动信号在从扫描线的起始端传递到末端的过程中会产生损耗, 从而导 致靠近扫描线末端的子像素的充电吋间延长, 使得整条扫描线上连接的子像素 充电吋间不均匀。
技术问题
[0004] 本申请实施例提供一种显示装置的驱动方法和驱动装置, 旨在解决由于扫描线 与数据线之间、 相邻扫描线之间、 扫描线与晶体管之间或者扫描线与子像素之 间存在寄生电容, 该寄生电容构成扫描线上的驱动负载, 使得扫描驱动信号在 从扫描线的起始端传递到末端的过程中会产生损耗, 从而导致靠近扫描线末端 的子像素的充电吋间延长, 使得整条扫描线上连接的子像素充电吋间不均匀的 问题。

[0045] 为了更清楚地说明本申请实施例中的技术方案, 下面将对实施例描述中所需要 使用的附图作简单地介绍, 显而易见地, 下面描述中的附图是本申请的一些实 施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动的前提下, 还可以 根据这些附图获得其他的附图。

[0051] 图 6是本申请的一个实施例提供的驱动装置的结构示意图。
[0052] 图 7是本申请的一个实施例提供的显示装置的结构示意图。
本发明的实施方式
[0053] 为了使本技术领域的人员更好地理解本申请方案, 下面将结合本申请实施例中 的附图, 对本申请实施例中的技术方案进行清楚地描述, 显然, 所描述的实施 例是本申请一部分的实施例, 而不是全部的实施例。 基于本申请中的实施例, 本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例, 都应当属于本申请保护的范围。
[0054] 本申请的说明书和权利要求书及上述附图中的术语"包括"以及它们任何变形, 意图在于覆盖不排他的包含。 例如包含一系列步骤或单元的过程、 方法或系统 、 产品或设备没有限定于已列出的步骤或单元, 而是可选地还包括没有列出的 步骤或单元, 或可选地还包括对于这些过程、 方法、 产品或设备固有的其它步 骤或单元。 此外, 术语"第一"、 "第二 "和"第三"等是用于区别不同对象, 而非用 于描述特定顺序。
[0055] 如图 1所示, 示例性的示出了一个包括 m行和 n列子像素的像素阵列, 其中, m 和 n大于 0且为正整数。
[0056] 可选的, 根据所采用的栅极驱动方式的不同, 扫描线的数量也不同。 若采用三 栅极驱动方式, 则每条扫描线对应连接一行子像素, 扫描线的数量与像素阵列 的行数相等; 若采用双栅极驱动方式, 则每三行子像素对应连接两条扫描线, 每三行子像素中的一行子像素对应连接其中一条扫描线, 每三行子像素中的另 外两行子像素对应连接另外一条扫描线, 扫描线的数量少于像素阵列的行数。
[0057] 图 1示例性的示出了采用三栅极驱动方式驱动的像素阵列, 包括 m条扫描线 (ga te line) 和 n条数据线 (data line) , 分别表示为 Gl、 G2、 G3、 Gm和 Sl、 S2
、 S3、 Sn。
[0058] 图 1所示的像素阵列的驱动原理为: [0059] 通过栅极驱动芯片 (Gate driver IC) 分别连接每条扫描线对像素阵列进行逐行 扫描驱动, 从与每行子像素对应连接的扫描线的起始端输入扫描驱动信号传递 到扫描线的末端, 对扫描线上连接的各个子像素进行逐个充电。
[0060] 由于扫描线与数据线之间、 相邻扫描线之间、 扫描线与晶体管之间或者扫描线 与子像素之间存在寄生电容, 该寄生电容构成扫描线上的驱动负载, 使得扫描 驱动信号在从扫描线的起始端传递到末端的过程中会产生损耗, 因此, 采用现 有的行扫描驱动方式对子像素进行行扫描驱动, 会导致靠近扫描线末端的子像 素的充电吋间延长, 产生信号延迟, 使得整条扫描线上连接的子像素充电吋间 不均匀。
[0061] 如图 2所示, 为了解决图 1所示的像素阵列在驱动过程中所产生的问题, 本申请 的一个实施例提供一种显示装置的驱动方法, 其包括:
[0062] 步骤 S101 : 分别对每行子像素进行分区, 将每行子像素的分区位置作为每行子 像素对应的扫描线的充电起始点位置;
[0063] 步骤 S102: 通过每条扫描线的充电起始点位置, 分别为每条扫描对应的一行子 像素的不同区域输入扫描电压信号, 以对每行子像素进行分区扫描。
[0064] 可选的, 每行子像素可以分为至少两个区域, 每条扫描线的充电起始点位置的 数量等于该条扫描线对应的一行子像素的分区数量减一, 即若一行子像素被划 分为 N个区域, 则该行子像素对应的扫描线的充电起始点数量为 N-l, 扫描线的 位置位于相邻的两个区域中间的位置。
[0065] 在一个实施例中, 每行子像素被分为两个区域。
[0066] 在一个实施例中, 若将每行子像素分为两个区域, 则将位于每行子像素之间的 中间点位置作为充电起始点位置, 所能实现的缩小扫描线两端连接的子像素之 间的充电吋间的差距的效果较好, 可以使得任意两个对称设置于中间点位置两 侧的子像素的充电吋间相等, 使中间点位置两侧的子像素的充电吋间以该中间 点位置为基准由近及远的依次递增。
[0067] 在一个实施例中, 每条扫描线的充电起始点位置相同;
[0068] 若每行子像素所包括的子像素个数为奇数, 则每条扫描线的充电起始点位置为 其所对应的一行子像素的中间子像素与扫描线的连接位置; [0069] 若每行子像素所包括的子像素个数为偶数, 则每条扫描线的充电起始点位置位 于其所对应的一行子像素的中间两个子像素之间。
[0070] 如图 3所示, 本申请的一个实施例示例性的示出了每行子像素所包括的子像素 个数为偶数吋, 每条扫描线的充电起始点位置相同的情况。 图 3中, 第 1条扫描 线 G1的充电起始点位于第 1行子像素的第 n/2个子像素和第 n/2+l个子像素之间, 第 2条扫描线 G2的充电起始点位于第 2行子像素的第 n/2个子像素和第 n/2+l个子像 素之间, 第 3条扫描线 G3的充电起始点位于第 3行子像素的第 n/2个子像素和第 n/2 + 1个子像素之间, ......, 第 m条扫描线 Gm的充电起始点位于第 m行子像素的第 n/
2个子像素和第 n/2+l个子像素之间; 其中, n为偶数。
[0071] 在一个实施例中, 每条扫描线的充电起始点位置不完全相同, 显示装置包括 N 条扫描线;
[0072] 第 i条扫描线的充电起始点位置为其对应的一行子像素中的第 j个子像素与第 i条 扫描线的连接位置;
[0073] 或者, 第 i条扫描线的充电起始点位置位于其对应的一行子像素中的第 j个子像 素与第 j-1个像素之间;
[0074] 其中, N≥i≥l, j > l£.N i和 j为正整数。
[0075] 可选的, 也可以根据实际需要将各扫描线的充电起始点设置为不同位置, 只要 保证充电起始点位置不是扫描线的起始端或末端即可。
[0076] 如图 4所示, 本申请的一个实施例示例性的示出了每条扫描线的充电起始点位 置不完全相同的情况。 图 4中, 第 1条扫描线 G1的充电起始点位于第 1行子像素的 第 2个子像素和第 3个子像素之间, 第 2条扫描线 G2的充电起始点位于第 2行子像 素的第 2个子像素和第 3个子像素之间, 第 3条扫描线 G3的充电起始点位于第 3行 子像素的第 3个子像素和第 4个子像素之间, ......, 第 m条扫描线 Gm的充电起始 点位于第 m行子像素的第 n- 1个子像素和第 n个子像素之间。
[0077] 可选的, 扫描线的数量由所采用的对像素阵列进行扫描驱动的方式决定, 图 3 和图 4所对应的实施例中所采用的驱动方式为三栅极驱动方式, 即像素阵列的行 子像素数量与显示装置的扫描线数量相等, 每条扫描线对应连接一行子像素。
[0078] 如图 5所示, 本申请的一个实施例提供一种驱动装置 100, 应用于显示装置 200 [0079] 其中, 显示装置 200包括:
