Description

显示面板驱动方法、 驱动装置及显示器件
技术领域
本发明的实施例涉及一种显示面板驱动方法、 驱动装置及显示器 件。
背景技术
在传统的显示器件中,显示模组部分的扫描驱动通常是通过一块信 号处理芯片控制栅极驱动电路,从而将栅极驱动信号按照预设时序传输 到显示面板上, 因此并不存在同步性问题。 但是在大尺寸或者高分辨率 的显示产品中, 由于同时需要处理的信号量变大, 一颗芯片通常无法完 成整张显示面板的扫描驱动,所以通常会采用多颗芯片分别对不同显示 区域同时进行扫描驱动, 多颗芯片之间的协调工作也就显得尤为重要。
常规的芯片设计中, 为了实现多颗芯片之间协调工作, 通常会在每 颗芯片中增加帧存储单元, 同时通过串行外设接口( Ser i a l Per i phera l Int erface Bus , 筒称 SP I ) 的信号在每两个芯片之间进行通信, 使两 个芯片同步工作。 该同步过程具体为两个芯片均预存一帧以上的画面, 通过 SP I信号两个芯片同时向各自所控制的显示区域发送数据。但是其 不足之处在于,多颗芯片之间以及每颗芯片的不同传输路径上的栅极驱 动信号仍然存在延时, 此外由于每颗芯片的内部均增加了存储器, 还将 进一步造成生产成本的上升。
发明内容
本发明的实施例提供一种显示面板驱动方法、 驱动装置及显示器 件, 可以改善分区域控制显示面板栅极驱动信号中存在的延时, 降低生 产成本。
为达到上述目的, 本发明的实施例采用如下技术方案:
本发明实施例的一方面, 提供一种显示面板驱动方法:

具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合 本发明实施例的附图, 对本发明实施例的技术方案进行清楚、 完整地描 述。 显然, 所描述的实施例是本发明的一部分实施例, 而不是全部的实 施例。基于所描述的本发明的实施例, 本领域普通技术人员在无需创造 性劳动的前提下所获得的所有其他实施例, 都属于本发明保护的范围。
除非另作定义,此处使用的技术术语或者科学术语应当为本发明所 属领域内具有一般技能的人士所理解的通常意义。本发明专利申请说明 书以及权利要求书中使用的 "第一" 、 "第二" 以及类似的词语并不表 示任何顺序、数量或者重要性, 而只是用来区分不同的组成部分。 同样, "一个" 或者 "一" 等类似词语也不表示数量限制, 而是表示存在至少 一个。 "包括"或者 "包含"等类似的词语意指出现在 "包括"或者 "包 含" 前面的元件或者物件涵盖出现在 "包括" 或者 "包含" 后面列举的 元件或者物件及其等同,并不排除其他元件或者物件。 "连接 "或者 "相 连"等类似的词语并非限定于物理的或者机械的连接, 而是可以包括电 性的连接, 不管是直接的还是间接的。 "上" 、 "下" 、 "左" 、 "右" 等仅用于表示相对位置关系, 当被描述对象的绝对位置改变后, 则该相 对位置关系也可能相应地改变。
本发明实施例提供的显示面板包括至少两个时序控制器和至少两 个显示区域, 每个时序控制器分别对应一个显示区域; 驱动方法包括: 每个时序控制器根据获取到的对应的显示区域的显示信号得到同步信 号, 同步信号包括对应的显示区域的首行扫描信号的起始时刻; 时序控 制器根据至少一个显示区域的同步信号调整所有显示区域的首行扫描 信号的起始时刻, 以使得所有显示区域的首行扫描信号的起始时刻相 同。
本发明实施例提供的显示面板驱动方法,在分区域控制的显示面板 中, 时序控制器之间通过对不同位置的同步信号进行差异化计算, 并通 过调节内部显示画面的起始位置, 实现了对时序信号的同步调节, 从而 有效改善了栅极驱动信号的延时。 此外, 这样一种结构的显示面板无需 设置大量的显示緩存单元, 从而大大降低了显示产品的生产成本。
进一步地, 以显示面板包括两个时序控制器, 即包括第一时序控制 器和第二时序控制器为例。 第一时序控制器对应第一显示区域, 第二时 序控制器对应第二显示区域。 本发明实施例提供的显示面板驱动方法, 如图 1所示, 包括以下步骤。
在 S 1 01 中, 第一时序控制器根据获取到的第一显示区域的显示信 号得到第一帧同步信号,该第一帧同步信号包括第一显示区域的首行扫 描信号的起始时刻。
在 S 1 02 中, 第二时序控制器根据获取到的第二显示区域的显示信 号得到第二帧同步信号,该第二帧同步信号包括第二显示区域的首行扫 描信号的起始时刻。
具体地, 例如, 时序控制器可以获取所对应的显示区域近端的显示 信号,通过该显示信号中所记录的时间信号得到显示区域的首行扫描信 号的起始时刻, 从而形成帧同步信号。
在 S 1 0 3中, 时序控制器根据第一帧同步信号和第二帧同步信号调 整第一显示区域和第二显示区域的首行扫描信号的起始时刻,以使得第 一显示区域的首行扫描信号的起始时刻与第二显示区域的首行扫描信 号的起始时刻相同,该两个时序控制器包括第一时序控制器和第二时序 控制器。
需要说明的是, 在本发明实施例所提供的分区控制显示面板中, 显 示面板包括多个显示区域, 并且显示面板至少包括两个时序控制器, 每 个时序控制器均与一个显示区域相对应,用于控制该显示区域内栅极驱 动信号的时序输出。 应当理解, 上述第一时序控制器和第二时序控制器 仅用于区别任意两个不同的时序控制器,而并非是对本发明中时序控制 器个数所做的限定。 当包括多个时序控制器时, 任意两个时序控制器之 间均可以满足上述方法步骤。
进一步地, 如图 2所示, 以显示面板包括两个时序控制器, 即包括 第一时序控制器和第二时序控制器为例,第一时序控制器对应第一显示 区域, 第二时序控制器对应第二显示区域, 本发明实施例提供的显示面 板驱动方法例如可以包括:
52 01、第一时序控制器根据获取到的第一显示区域的显示信号得到 第一帧同步信号,该第一帧同步信号包括第一显示区域的首行扫描信号 的起始时刻;
52 02、第二时序控制器根据获取到的第二显示区域的显示信号得到 第二帧同步信号,该第二帧同步信号包括第二显示区域的首行扫描信号 的起始时刻;
S 2 0 3、 第一时序控制器接收第二时序控制器发送的第二帧同步信 号,根据第一帧同步信号和第二帧同步信号调整第一显示区域的首行扫 描信号的起始时刻;
S 2 04、 第二时序控制器接收第一时序控制器发送的第一帧同步信 号,根据第一帧同步信号和第二帧同步信号调整第二显示区域的首行扫 描信号的起始时刻。
例如,当第一时序控制器和第二时序控制器根据其所对应的显示区 域的显示信号生成帧同步信号之后,可以将各自的帧同步信号发送至其 他时序控制器(即对第一时序控制器来说, 其将帧同步信号发送到除第 一时序控制器之外的其他时序控制器, 对第二时序控制器来说, 其将帧 同步信号发送到除第二时序控制器之外的其他时序控制器), 以便时序 控制器调整首行扫描信号的起始时刻。
例如, 当仅包括第一时序控制器和第二时序控制器时, 根据第一帧 同步信号和第二帧同步信号调整首行扫描信号的起始时刻可以包括: 根据第一帧同步信号和第二帧同步信号得到第一显示区域的首行 扫描信号的起始时刻与第二显示区域的首行扫描信号的起始时刻之间 的第一延时量 t l ;
将第一显示区域的首行扫描信号的起始时刻与第二显示区域的首 行扫描信号的起始时刻分别提前或延后该第一延时量的一半 t l /2 , 以 使得第一显示区域的首行扫描信号的起始时刻与第二显示区域的首行 扫描信号的起始时刻相同。
这样一来,当第一显示区域与第二显示区域的近端显示信号出现延 时时, 例如, 根据两区域显示的延时量为 t l , 只需要同时将显示信号 时序较为靠前一侧的信号时序延后该延迟量的一半 t l /2 , 将显示信号 时序较为靠后一侧的信号时序提前该延迟量的一半 t l / 2即可实现两个 显示区域显示的同步。采用这样一种显示面板驱动方法可以筒单的实现 分区控制的同步。
或者, 当包括两个以上的时序控制器时, 可以将其中一个时序控制 器所对应的显示区域内的首行扫描信号的起始时刻作为标准时刻,其余 时序控制器按照该标准时刻对各自显示区域内的首行扫描信号时序进 行提前或延后调整,以消除不同显示区域内的首行扫描信号的起始时刻 的延迟量, 从而实现分区控制的同步。
需要说明的是, 在本发明实施例中, 时序控制器的内部可以增设少 量的行寄存器, 通过在显示信号处理中, 在垂直方向上插入或去除无效 数据时间(V-b l ank ing 时间)来实现扫描信号时序的提前或延后。 由于 时序控制器内增加了若干行的寄存器,因此提前或延后若干行信号并不 会对显示造成影响。
此外, 显示面板驱动方法, 还可以包括: 每个时序控制器根据获取到的对应显示区域的显示信号得到同步 信号, 同步信号还包括对应显示区域的末行扫描信号的起始时刻; 时序控制器根据首行扫描信号的起始时刻和末行扫描信号的起始 时刻调整对应显示区域内每一行扫描信号的起始时刻,以消除对应显示 区域内每一行扫描信号的起始时刻的延时量。
例如, 如图 2所示, 以显示面板包括两个时序控制器, 即包括第一 时序控制器和第二时序控制器为例, 第一时序控制器对应第一显示区 域, 第二时序控制器对应第二显示区域, 本发明实施例提供的显示面板 驱动方法还可以包括:
S205、第一时序控制器根据获取到的第一显示区域的显示信号得到 第三帧同步信号,该第三帧同步信号包括第一显示区域的末行扫描信号 的起始时刻。
S206、第一时序控制器根据第一帧同步信号和第三帧同步信号调整 第一显示区域内每一行扫描信号的起始时刻,以消除第一显示区域内每 一行扫描信号的起始时刻的延时量。
其中, 由于生产制作工艺或外界环境的原因, 显示区域远端的行扫 描信号较近端行扫描信号通常具有延时,可以通过采集远端的帧同步信 号消除传输路径上存在的延时。
例如,第一时序控制器根据第一帧同步信号和第三帧同步信号调整 第一显示区域内每一行扫描信号的起始时刻的处理可以包括:
第一时序控制器根据第一帧同步信号和第三帧同步信号得到第一 显示区域的末行扫描信号的起始时刻与首行扫描信号的起始时刻之间 的第二延时量。
将第一显示区域内每一行扫描信号的起始时刻均根据该第二延时 量进行提前调整,以消除第一显示区域内每一行扫描信号的起始时刻的 延时量。
例如,第一时序控制器根据第一帧同步信号和第三帧同步信号得到 第一显示区域的末行扫描信号的起始时刻与首行扫描信号的起始时刻 之间的第二延时量 t 2。 通常栅极扫描线在垂直方向上等距离设置, 根 据显示信号的垂直分辨率 n , 可以得到每一行信号在传输过程中相对于 上一行信号发生的延时 t 2/ ( n-l ) , 此时时序控制器内部可以通过调 节栅极驱动信号在不同行时的起始信号位置,即第 m行栅极驱动信号的 起始位置提前(m-1 ) *t2/ ( n-1 ) 。 这样即可消除显示区域内由于信号 传输路径造成的延时影响。
需要说明的是, 在上述实施例中, 第一时序控制器针对对应的显示 区域内由于信号传输路径造成延时所进行栅极驱动信号时序调整的过 程同样适用于其他时序控制器。 也就是说, 其他时序控制器, 如第二时 序控制器, 也可以进行步骤 S205和 S206, 来消除第二显示区域内的每 一行扫描信号起始时刻的延时量。 在此也仅是举例说明, 而并非对本发 明所做的限制。
以下可以参照图 3所示的信号处理流程图,以显示面板划分为左右 两部分显示区域,这两个显示区域分别对应各自的时序控制器为例对本 发明实施例所提供的显示面板驱动方法进行详细说明。
在如图 4所示的显示面板中, 左右时序控制器 R分别获得近端 的显示信号 (S302 ) , 并形成相应的帧同步信号 STV_L和 STV_R(以后 缀 L和 R分别表示左时序控制器和右时序控制器) (S303 ) , 这些帧同 步信号将被输出至显示面板的近端, 以控制栅极驱动器的初始化。 与此 同时, 左右时序控制器 R分别输出栅极驱动信号 0E_L和 0E_R。 帧 同步信号 STV_L和 STV_R在分别经过左右两侧的传输路径后,有可能因 为工艺原因, 形成不同的信号延时, 在远端可采集到延时后的 STV, -L 与 STV, -R信号(远端控制信号增加 ", " 以便区分于近端)。
两个时序控制器之间分别向对方传输各自的帧同步信号 STV, 以便 进行比对(S304 ) 。 当一个时序控制器获得对方的 STV信号后, 首先对 比 STV_L与 STV_R信号, 可以得到两个信号的延时差异 tl ( S305 ) 。 如图 5所示,此时对左右两个显示区域分别进行调整,其中,由于 STV_L 的时序较为靠前,左侧显示画面延后 tl/2时间,右侧显示画面提前 tl/2 时间 (S306 ) , 这样即可筒单的实现分区控制的同步。 该方法可通过在 显示信号处理的过程中, 插入或去除垂直方向 V-blanking时间实现。 由于时序控制器内增加了若干行的寄存器,因此提前或延后若干行信号 并不会对显示造成影响。 至此, 即可消除由于近端信号处理造成的延时 问题。
在消除延时问题的显示区域内,由于信号传输路径造成的延时的过 程中, 需要对远端的 STV信号进行采集( S 308 ) 。 因为在传统显示面板 中需要进行显示画面的反转,所以都会将这远端的 STV信号引线至外部 电路, 因此该信号可以采用现有技术中的相关方法获得。 本发明对此并 不做限制。 左右区域的时序控制器分别比对各自区域的 STV与 STV, 信 号, 获得该区域垂直方向因为信号传输路径造成的不同的延时量 t 2或 1 3 ( S 309 ) , 如图 6所示。 以左侧显示区域为例, 时序控制器内部根据 显示信号的垂直分辨率 n , 可以得到每一行信号在传输过程中相对于上 一行信号发生的延时 t 2 / ( n-1 ) , 此时时序控制器内部调节栅极驱动 信号在不同行时的起始信号位置, 即第 m行, 栅极驱动信号的起始位置 提前 (m_ l ) * t 2 / ( n-1 ) ( S 31 0-S 31 1 ) 。 至此, 即可消除左、 右两个 显示区域由于各自的信号传输路径造成的不同延时影响,从而实现了两 显示区域之间以及任意显示区域内部的显示效果一致。
本发明实施例提供的显示面板驱动方法,在分区域控制的显示面板 中, 时序控制器之间通过对不同位置的同步信号进行差异化计算, 并通 过调节内部显示画面的起始位置, 实现了对时序信号的同步调节, 从而 有效改善了栅极驱动信号的延时。 此外, 这样一种结构的显示面板无需 设置大量的显示緩存单元, 从而大大降低了显示产品的生产成本。

每个时序控制器根据获取到的用于各自显示区域的显示信号得到 同步信号, 同步信号包括用于各自显示区域的首行扫描信号的起始时 刻;时序控制器根据至少两个时序控制器的显示区域的同步信号调整首 行扫描信号的起始时刻,以使得不同显示区域的首行扫描信号的起始时 刻相同。
本发明实施例提供的显示面板驱动装置, 例如, 如图 4所示, 包括 至少两个时序控制器, 每个时序控制器对应一个显示区域。 其中, 以显 示面板包括两个时序控制器即包括第一时序控制器和第二时序控制器 为例对该实施例进行说明。 第一时序控制器对应第一显示区域, 第二时 序控制器对应第二显示区域。
第一时序控制器 41 , 用于根据获取到的第一显示区域的显示信号 得到第一帧同步信号,该第一帧同步信号包括第一显示区域的首行扫描 信号的起始时刻。
第二时序控制器 42 , 用于根据获取到的第二显示区域的显示信号 得到第二帧同步信号,该第二帧同步信号包括第二显示区域的首行扫描 信号的起始时刻。
时序控制器还用于根据第一帧同步信号和第二帧同步信号调整首 行扫描信号的起始时刻,以使得第一显示区域的首行扫描信号的起始时 刻与第二显示区域的首行扫描信号的起始时刻相同。
本发明实施例提供的显示面板驱动装置,在分区域控制的显示面板 中, 时序控制器之间通过对不同位置的同步信号进行差异化计算, 并通 过调节内部显示画面的起始位置, 实现了对时序信号的同步调节, 从而 有效改善了栅极驱动信号的延时。 此外, 这样一种结构的显示面板无需 设置大量的显示緩存单元, 从而大大降低了显示产品的生产成本。
需要说明的是, 在本发明实施例所提供的分区控制显示面板中, 显 示面板包括多个显示区域, 时序控制器至少包括两个时序控制器, 每个 时序控制器均与一个显示区域相对应,用于控制该显示区域内栅极驱动 信号的时序输出。 应当理解, 上述第一时序控制器和第二时序控制器仅 用于区别任意两个不同的时序控制器,而并非是对本发明中时序控制器 个数所做的限定。 当包括多个时序控制器时, 任意两个时序控制器之间 均可以满足上述方法步骤。
进一步地,以显示面板包括两个时序控制器即包括第一时序控制器 和第二时序控制器为例, 第一时序控制器对应第一显示区域, 第二时序 控制器对应第二显示区域, 第一时序控制器还可以用于:
根据获取到的第一显示区域的显示信号得到第三帧同步信号,该第 三帧同步信号包括第一显示区域的末行扫描信号的起始时刻。
根据第一帧同步信号和第三帧同步信号调整第一显示区域内每一 行扫描信号的起始时刻,以消除第一显示区域内每一行扫描信号的起始 时刻的延时量。
其中, 由于生产制作工艺或外界环境的原因, 显示区域远端的行扫 描信号较近端行扫描信号通常具有延时,可以通过采集远端的帧同步信 号消除传输路径上存在的延时。
例如,第一时序控制器根据第一帧同步信号和第三帧同步信号调整 第一显示区域内每一行扫描信号的起始时刻具体过程可以包括: 第一时序控制器根据第一帧同步信号和第三帧同步信号得到第一 显示区域的末行扫描信号的起始时刻与首行扫描信号的起始时刻之间 的第二延时量。
将第一显示区域内每一行扫描信号的起始时刻均根据该第二延时 量进行提前调整,以消除第一显示区域内每一行扫描信号的起始时刻的 延时量。
例如,第一时序控制器根据第一帧同步信号和第三帧同步信号得到 第一显示区域的末行扫描信号的起始时刻与首行扫描信号的起始时刻 之间的第二延时量 t 2。 通常栅极扫描线在垂直方向上等距离设置, 根 据显示信号的垂直分辨率 n , 可以得到每一行信号在传输过程中相对于 上一行信号发生的延时 t 2/ ( n-l ) , 此时时序控制器内部可以通过调 节栅极驱动信号在不同行时的起始信号位置,即第 m行栅极驱动信号的 起始位置提前(m-1 ) * t 2 / ( n-1 ) 。 这样即可消除显示区域内由于信号 传输路径造成的延时影响。
需要说明的是, 在上述实施例中, 第一时序控制器针对对应的显示 区域内由于信号传输路径造成延时所进行栅极驱动信号时序调整的过 程同样适用于其他时序控制器。 本发明的实施例在此也仅是举例说明, 而并非对本发明所做的限制。
