本发明涉及显示技术领域， 尤其涉及一种显示控制系统及控制方 法、 显示装置。 背景技术
传统的液晶显示装置正常工作时， 由包括发光灯条 （LED 灯条） 的背光模组工作提供背光源； 当待机状态时， 液晶显示装置不再更新 任何画面， 同时背光模组关闭。 也就是说在待机情况下， 整个液晶显 示装置都是在关闭的状态下， 如果要显示内容， 需要重新开机。
目前的智能应用服务器通常会支持后台推送信息的功能， 即当有 信息送达， 或者关键新闻、 天气变化时， 相应的软件会提示用户有重 要信息， 在目前的手机、 电视等产品上， 如果有类似的后台推送信 息， 通常是以外部的 LED指示灯实现。 以上介绍的传统技术， 只能实 现后台推送信息的提示， 但并不能够显示主要内容， 如果要显示完整 的信息内容， 则需要完全打开液晶显示装置获取信息， 开关的过程中 不仅操作不便， 同时也会造成不必要的电能损耗。
因此， 针对上述问题本发明提出一种新的显示控制系统及控制方 法、 显示装置。 发明内容
本发明的目的是： 提供一种显示控制系统及控制方法、 显示装置； 解决现有显示装置在待机状态时只能实现后台推送信息的提示， 而不 能显示后台推送消息内容的问题。
根据本发明的一个方面， 提供了一种显示控制系统。 该显示系统 包括多个源极驱动芯片， 与多个源极驱动芯片相连的开机时序控制器， 用于向多个源极驱动器芯片提供第一源极驱动信号， 与多个源极驱动 芯片相连的待机时序控制器， 用于向多个源极驱动器芯片提供第二源 极驱动信号， 以及多个栅极驱动芯片。 其中， 开机时序控制器与多个 栅极驱动芯片串联以向多个栅极驱动芯片提供第一栅极时序信号， 并 且待机时序控制器与多个栅极驱动芯片串联， 以向多个栅极驱动芯片 中的至少一个提供第二栅极时序信号。
根据本发明的一个方面， 通过采用开机时序控制器和待机时序控 制器， 可实现显示装置在待机状态时的后台推送消息显示。 这解决了 现有显示装置在待机状态时只能实现后台推送信息的提示， 而不能显 示后台推送消息内容的问题。 显示装置无需开启即可显示后台推送消 息的内容， 因此， 简化了用户对消息内容获取的过程， 节省了因需获 取信息内容而频繁开机所造成的电能损耗。
根据本发明的一个实施例， 还包括背光源驱动芯片； 所述开机时 序控制器和待机时序控制器均与所述背光源驱动芯片连接。
进一步地， 还包括状态控制模块； 所述状态控制模块分别连接各 所述栅极驱动芯片。
进一步地， 还包括主控制器， 该主控制器分别连接所述开机时序 控制器和所述待机时序控制器。
根据本发明的另一方面， 提供了一种显示装置， 包括如所述的显 示控制系统。 该显示装置还包括背光模组、 阵列基板、 彩膜基板和密 封于所述阵列基板与彩膜基板之间的液晶层； 所述阵列基板内安装有 多个晶体管； 所述栅极驱动芯片与各晶体管栅极连接； 所述源极驱动 芯片与各晶体管源极连接。
根据本发明的再一方面， 提供了一种在显示装置上显示推送消息 的方法。 该方法包括如下步骤： 接收推送消息； 确定所述显示装置的 状态； 以及根据所确定的显示装置的状态来显示所述推送消息。 其中， 在待机状态下， 通过待机时序控制器来产生待机状态源极驱动信号和 待机状态栅极时序信号以及在开机状态下， 通过开机时序控制器来产 生开机状态源极驱动信号和待机状态栅极时序信号。
以此通过各晶体管驱动所述显示装置在开机状态下显示后台推送 消息。
待机状态时， 所述待机时序控制器根据后台推送消息编辑待机状 态源极驱动信号和待机状态栅极时序信号， 分别发送给所述源极驱动 芯片和所述栅极驱动芯片。
所述源极驱动芯片根据待机状态源极驱动信号对各晶体管的源极 进行驱动控制； 所述栅极驱动芯片根据待机状态栅极时序信号对各晶 体管的栅极进行时序控制。 以此通过各晶体管驱动所述显示装置在待机状态下显示后台推送 消息。
进一步地， 所述状态控制模块检测显示装置的工作状态， 并根据 工作状态编辑开机状态切换指令或待机状态切换指令发送给所述栅极 驱动芯片；
所述栅极驱动芯片根据开机状态切换指令或待机状态切换指令在 开机状态栅极时序信号和待机状态栅极时序信号之间进行选择并执 行。
进一步地， 当所述状态控制模块检测到显示装置的工作状态为开 机状态时， 则编辑开机状态切换指令发送给所述栅极驱动芯片； 所述 栅极驱动芯片随即选择执行开机状态栅极时序信号， 以对各晶体管的 栅极进行时序控制；
当所述状态控制模块检测到显示装置的工作状态为待机状态时， 则编辑待机状态切换指令发送给所述栅极驱动芯片； 所述栅极驱动芯 片随即选择执行待机状态栅极时序信号， 以对各晶体管的栅极进行时 序控制。
根据本发明的一个实施例， 在待机状态时， 所述待机时序控制器 在预设的信息显示时间段内， 间断式驱动显示装置对后台推送;肖 , 进 行显示； 直至预设的信息显示时间段结束或用户选择关闭后台推送消 息的显示。
通过采用所述待机时序控制器在预设的信息显示时间段内， 间断 式驱动显示装置对后台推送消息进行显示， 可使待机时序控制器不需 要持续的处理高频率信号， 由此进一步节省了功耗， 延长了使用寿命。
进一步地， 待机状态时， 所述待机时序控制器发送待机状态栅极 时序信号给其中一个所述栅极驱动芯片； 该栅极驱动芯片根据待机状 态栅极时序信号对与之连接的部分晶体管的栅极进行时序控制； 以此 通过部分晶体管驱动所述显示装置的部分显示区域在待机状态下显示 后台推送消息。
进一步地， 开机状态时， 所述背光源驱动芯片接收所述开机时序 控制器发送的开机状态背光驱动信号， 并根据开机状态背光驱动信号 驱动发光灯条发光；
待机状态时， 所述背光源驱动芯片接收所述待机时序控制器发送 的待机状态背光驱动信号， 并根据待机状态背光驱动信号驱动发光灯 条发光。
本发明采用在待机状态时， 待机时序控制器通过对后台推送信息 的分析， 判断出该后台推送信息位于显示装置显示区域上的显示位置； 并对应驱动与该显示位置相对应一侧或两侧的发光灯条发光的步骤； 可以实现根据后台推送信息的具体显示位置的不同， 有针对性的分别 驱动显示区域的左、 右两侧的发光灯条工作； 例如， 当后台推送信息 位于显示区域的左侧时， 则待机时序控制器驱动位于显示区域左侧的 发光灯条发光， 而位于右侧的发光灯条则不发光， 以此进一步有效降 低显示控制系统整个控制过程的功耗。 附图说明
以下结合附图和实施例对本发明作进一步说明。
图 1是根据本发明一个实施例的显示控制系统的框图；
图 2 是根据本发明一个实施例来显示推送消息的控制方法的流程 图； 以及
图 3 是根据本发明一个实施例在待机状态下显示推送消息内容的 具体界面。 具体实施方式
参见图 1 所示， 根据本发明的一个实施例提供了一个显示控制系 统 100 , 其包括多个源极驱动芯片 110a, 110b , 110c, 多个栅极驱动芯 片 120a, 120b , 120c, 开机时序控制器 130和待机时序控制器 140。 其 中， 各所述源极驱动芯片 110a, 110b , 110c分别与开机时序控制器 130 和待机时序控制器 140连接。 各所述源极驱动芯片 110a, 110b , 110c 之间并联； 所述开机时序控制器 130与多个所述栅极驱动芯片 120a, 120b , 120c串联。 各所述栅极驱动芯片 120a, 120b , 120c之间以级联 的方式串联。 所述待机时序控制器 140 也与多个所述栅极驱动芯片串 联 120a, 120b , 120c。
根据本发明的一个实施例， 所述开机时序控制器 130 根据开机状 态指令编辑开机状态源极驱动信号和开机状态栅极时序信号， 分别发 送给各所述源极驱动芯片 110a, 110b , 110c 和各所述栅极驱动芯片 120a, 120b , 120c。
所述待机时序控制器 140从主控制器 180接收状态指令， 根据待 机状态指令编辑待机状态源极驱动信号和待机状态栅极时序信号并且 分别发送给各所述源极驱动芯片 110a, 110b , 110c和各所述栅极驱动 芯片 120a, 120b , 120c。
所述源极驱动芯片 110a, 110b , 110c与阵列基板中各各晶体管的 源极连接， 并根据开机状态源极驱动信号或待机状态源极驱动信号对 各晶体管的源极进行驱动控制。
所述栅极驱动芯片 120a, 120b , 120c与阵列基板中各各晶体管的 栅极连接， 并根据开机状态栅极时序信号或待机状态栅极时序信号对 各晶体管的栅极进行时序控制。 不同的栅极控制芯片 120a, 120b , 120c 对应于不同的显示区域。 尽管在附图 1 的实施例中， 待机时序控制器 140被串联至所有的栅极驱动芯片 120a, 120b , 120c, 但是本领域技术 人员可以理解， 当需要显示的待机信息的内容比较少时， 待机时序控 制器 140 可以仅连接至一部分的栅极驱动芯片， 例如， 仅仅与栅极驱 动芯片 120c相连， 从而在待机时只在与该栅极驱动芯片相对应的显示 区域中显示推送消息的内容。 当需要显示比较大面积的待机信息， 则 需要控制更多个栅极驱动芯片。 在工作中， 当需要在与多个栅极驱动 芯片对应的区域中显示推送消息的内容时， 各个栅极驱动芯片 120a, 120b , 120c被按照次序依次驱动。
本发明采用开机时序控制器 130和待机时序控制器 140两个时序 控制器的设计， 可实现显示装置在待机状态时的后台推送消息显示， 解决了现有显示装置在待机状态时只能实现后台推送信息的提示， 而 不能显示后台推送消息内容的问题； 使显示装置无需开启即可显示后 台推送消息的内容， 简化了用户对消息内容获取的过程， 节省了因需 获取信息内容而频繁开机所造成的电能损耗。
此外， 通过设置两个时序控制器， 可以区分正常显示与待机显示 时不同的驱动时序。 由于待机显示的推送消息的内容比较简单 （如文 字）， 所以对于图像的处理要求不高， 待机时序控制器 140中对图像的 处理也会变得简单， 对于图像刷新率的要求也不需要很高， 工作时功 耗降低。
根据本发明的一个实施例， 所述显示控制系统 100 还包括背光源 驱动芯片 150。所述开机时序控制器 130和待机时序控制器 140均与所 述背光源驱动芯片 150连接。 所述背光源驱动芯片 150连接至少两个 发光灯条 160;所述发光灯条 160安装在显示装置的背光模组中用作显 示装置的背光源。
所述背光源驱动芯片 150接收所述开机时序控制器 130发送的开 机状态背光驱动信号或所述待机时序控制器 140 发送的待机状态背光 驱动信号， 并根据开机状态背光驱动信号或待机状态背光驱动信号驱 动发光灯条发光。
根据本发明的一个实施例， 所述显示控制系统 100 还包括状态控 制模块 170。 所述状态控制模块 170 分别连接各所述栅极驱动芯片 120a, 120b , 120c。
本实施例中所述状态控制模块 170 检测显示装置的工作状态， 并 根据工作状态编辑开机状态切换指令或待机状态切换指令发送给各所 述栅极驱动芯片 120a, 120b , 120c。 根据本发明的一个实施例， 在待 机状态时， 只需要在显示装置上的特定区域内显示推送消息的内容。 状态控制模块 170控制各个栅极驱动芯片 120a, 120b , 120c的开关， 以在待机模式下只驱动部分栅极驱动芯片用于显示。
所述栅极驱动芯片 120a, 120b , 120c根据开机状态切换指令或待 机状态切换指令在开机状态栅极时序信号和待机状态栅极时序信号之 间进行选择并执行。
例如， 当所述状态控制模块 170 检测到显示装置的工作状态为开 机状态时， 则编辑开机状态切换指令发送给所述栅极驱动芯片 120a,
120b , 120c。 所述栅极驱动芯片 120a, 120b , 120c随即选择执行开机 状态栅极时序信号， 以对各晶体管的栅极进行时序控制。 反之， 当所 述状态控制模块 170 检测到显示装置的工作状态为待机状态时， 则编 辑待机状态切换指令发送给所述栅极驱动芯片 120a, 120b , 120c。 所 述栅极驱动芯片 120a, 120b , 120c随即选择执行待机状态栅极时序信 号， 以对各晶体管的栅极进行时序控制。
通过上述说明可知， 通过状态控制模块 170 可控制栅极驱动芯片 120a, 120b , 120c 在开机时序控制器和待机时序控制器之间进行控制 切换。也就是说，当显示装置处于开机状态时，所述栅极驱动芯片 120a, 120b , 120c被切换至由开机时序控制器 130进行控制。 否则， 则由待 机时序控制器 140 进行控制。 通过对阵列基板分别在两种状态下进行 不同控制， 显示装置可以在开机状态和待机状态两种工作状态下均能 实现后台推送消息的显示。
本实施例中所述显示控制系统还包括主控制器 180。 该主控制器 180分别连接所述开机时序控制器 130和所述待机时序控制器 140。 所 述主控制器 180通过有线网络或无线网络与智能应用服务器 190连接， 用于接收智能应用服务器 190 实时发送的后台推送消息， 并根据后台 推送消息编辑开机状态指令和待机状态指令， 并分别发送至开机时序 控制器 130和待机时序控制器 140。
本发明中所述待机时序控制器 140 输出用于控制阵列基板中各晶 体管源极 110a, 110b , 110c的待机状态源极驱动信号， 以及用于控制 阵列基板中各晶体管栅极 120a, 120b , 120c的待机状态栅极时序信号； 通过这两组信号的匹配实现显示装置的驱动。
根据本发明的一个实施例， 还提供了一种显示装置。 其包括如上 述中所述显示控制系统 100以及显示面板。 该显示面板包括背光模组、 阵列基板、 彩膜基板和密封于所述阵列基板与彩膜基板之间的液晶层。 所述阵列基板内安装有多个用于驱动显示装置显示图像的晶体管。 所 述栅极驱动芯片对应排布在所述阵列基板两侧 , 并与该阵列基板内的 各晶体管栅极连接。 所述源极驱动芯片对应排布在所述阵列基板底端， 并与该阵列基板内的各晶体管源极连接。 所述栅极驱动芯片对应连接 所述阵列基板中各各晶体管的栅极。 所述源极驱动芯片对应连接所述 阵列基板中各各晶体管的源极。 所述背光源驱动芯片连接所述背光模 组中的发光灯条， 所述发光灯条分设在所述背光模组两侧。
根据本发明的一个实施例还提供一种在显示装置上显示推送消息 的方法。 以下结合附图 1 中所描述的显示控制系统来详细介绍在显示 装置上显示推送消息的方法。 该方法包括如下步骤：
主控制器 180从远程的智能应用服务器 190接收推送消息。 所述 推送消息例如是天气预报、 突发新闻等实时消息， 或者客户自定义的 信息， 例如在显示装置上显示的记事贴。
主控制器 180 在接收到推送消息之后确定显示装置的状态， 并且 结合具体的显示状态来确定如何显示所述推送消息。 在附图 2 中示例 了如何根据不同状态来显示推送消息的具体操作方法。 201、 开机状态时， 所述开机时序控制器 130根据接收到的后台推 送消息编辑开机状态源极驱动信号和开机状态栅极时序信号， 分别发 送给所述源极驱动芯片 110a, 110b , 110c和所述栅极驱动芯片 120a, 120b , 120c。
202、 所述源极驱动芯片 110a, 110b , 110c才艮据开机状态源极驱动 信号对各晶体管的源极进行驱动控制。 同时， 所述栅极驱动芯片 120a,
120b , 120c根据开机状态栅极时序信号对各晶体管的栅极进行时序控 制；
以此通过各晶体管驱动所述显示装置在开机状态下显示后台推送 消息。
203、 待机状态时， 所述待机时序控制器 140根据接收到的后台推 送消息编辑待机状态源极驱动信号和待机状态栅极时序信号， 分别发 送给所述源极驱动芯片 110a, 110b , 110c和所述栅极驱动芯片 120a, 120b , 120c。
204、 所述源极驱动芯片 110a, 110b , 110c根据待机状态源极驱动 信号对各晶体管的源极进行驱动控制。 同时， 所述栅极驱动芯片 120a,
120b , 120c根据待机状态栅极时序信号对各晶体管的栅极进行时序控 制；
以此通过各晶体管驱动所述显示装置在待机状态下显示后台推送 消息。
在待机状态时， 只有在接收到后台推送信息时， 待机时序控制器
140才开始驱动。未接收后台推送信息时，待机时序控制器 140不驱动 , 显示装置始终处于待机状态。 在附图 3 中给出了在待机状态下， 在显 示装置的部分显示区域中显示推送消息的一个具体显示界面 300。在附 图 3 中要被显示的待机推送消息是实时的天气预报。 其被显示在显示 装置底部的显示区域 310 中。 除了显示推送消息的内容之外， 还可以 在该显示区域中显示处于待机运行状态的其他应用的状态， 例如， 电 子邮件、 QQ以及微博等的状态。
本实施例中所述状态控制模块 170 检测显示装置的工作状态， 并 根据工作状态编辑开机状态切换指令或待机状态切换指令发送给相应 的栅极驱动芯片 120a, 120b , 120c。 如图 3所示， 在待机状态下， 显 示装置可能只需要在部分区域中显示推送消息的内容。 因此， 相应的， 状态控制模块 170只需要控制与显示区域相对应的部分栅极驱动芯片。 通过对于待机时序控制器所输出的栅极时序信号进行调整， 以定义不 同的时序， 可以驱动不同的栅极驱动芯片， 以实现在不同区域的显示。 例如， 从显示装置上部到显示装置下部， 利用不同的显示区域来显示 推送消息的内容。
所述栅极驱动芯片根据开机状态切换指令或待机状态切换指令在 开机状态栅极时序信号和待机状态栅极时序信号之间进行选择并执 行。
本实施例中当所述状态控制模块检测到显示装置的工作状态为开 机状态时， 则编辑开机状态切换指令发送给所述栅极驱动芯片。 所述 栅极驱动芯片随即选择执行开机状态栅极时序信号， 以对各晶体管的 栅极进行时序控制。
当所述状态控制模块检测到显示装置的工作状态为待机状态时， 则编辑待机状态切换指令发送给栅极驱动芯片。 所述栅极驱动芯片随 即选择执行待机状态栅极时序信号， 以对各晶体管的栅极进行时序控 制。
根据本发明的一个优选实施例， 当显示装置处于待机状态时， 所 述待机时序控制器 140 在预设的信息显示时间段内， 间断式驱动显示 装置对后台推送消息进行显示， 直至预设的信息显示时间段结束或用 户选择关闭后台推送消息的显示。
具体地说， 在某一信息显示时间段内间断划分出多个驱动开启时 间点和多个驱动关闭时间点； 当驱动时间到达驱动关闭时间点时， 所 述待机时序控制器停止驱动显示装置显示后台推送消息； 当驱动时间 到达驱动开启时间点时， 所述待机时序控制器开始驱动显示装置显示 后台推送消息。 通过间断式的驱动显示装置， 该实施例使待机时序控 制器不需要持续的处理高频率信号， 节省了功耗， 并且延长了显示装 置的使用寿命。
当显示装置处于待机状态时， 所述待机时序控制器 140 发送待机 状态栅极时序信号给其中一个所述栅极驱动芯片。 该栅极驱动芯片根 据待机状态栅极时序信号对与之连接的部分晶体管的栅极进行时序控 制， 以此通过部分晶体管驱动所述显示装置的部分显示区域在待机状 态下显示后台推送消息。 当显示装置处于开机状态时， 所述背光源驱动芯片接收所述开机 时序控制器发送的开机状态背光驱动信号， 并根据开机状态背光驱动 信号驱动发光灯条发光。
当显示装置处于待机状态时， 所述背光源驱动芯片接收所述待机 时序控制器发送的待机状态背光驱动信号， 并根据待机状态背光驱动 信号驱动发光灯条发光。
优选地， 当显示装置处于待机状态时， 待机时序控制器通过对后 台推送信息的分析， 判断出该后台推送信息位于显示装置显示区域上 的显示位置； 并对应驱动与该显示位置相对应一侧或两侧的发光灯条 发光。 这样就可以实现根据后台推送信息的具体显示位置的不同， 有 针对性的分别驱动显示区域的左、 右两侧的发光灯条工作； 例如， 当 后台推送信息位于显示区域的左侧时， 则待机时序控制器驱动位于显 示区域左侧的发光灯条发光， 而位于右侧的发光灯条则不发光， 以此 进一步有效降低显示控制系统整个控制过程的功耗。
虽然结合一些实施例描述了本发明， 但是并不打算将本发明限制 于在这里阐述的特定形式。 相反， 本发明的范围仅利用所附的权利要 求书来限制。 在权利要求书中， 术语包括并不排除其他元素或步骤的 存在。 此外， 虽然单个地列出， 但是多个装置、 元素或方法步骤可以 利用例如单个单元或处理器来实施。 此外， 虽然个别特征可以被包括 在不同的权利要求中， 但是这些特征可能可以有利地进行组合。
