具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普 通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
请参阅图1，本公开实施例提供的显示装置包括显示面板和显示控制器，显示控制器包括显示驱动器5、数据存储器400、模式触发器1，以及用于控制显示面板处在正常显示模式或待机显示模式的模式控制器3；模式触发器1的输出端与模式控制器3的输入端连接，模式控制器3的输出端分别与信号切换器4的控制端和显示驱动器5的控制端连接，信号切换器4的输出端分别与正常显示信号端子401以及与数据存储器400相接的待机显示信号端子402连接，正常显示信号端子401和待机显示信号端子402分别与显示驱动器5的输入端连接。
具体实施时，在待机条件下需要显示显示装置所自带的信息时，模式触发器1发出第一触发电信号给模式控制器3，使得模式控制器3根据第一触发电信号控制显示驱动器5工作，信号切换器4根据第一触发电信号使得待机显示信号端子402向显示驱动器5提供待机显示信号，该待机显示信号为数据存储器400所存储的显示装置自带的信息。
在需要正常显示时，通过模式触发器1发出第二触发电信号给模式控制器3，使得模式控制器3根据第二触发电信号控制显示驱动器5工作，信号切换器4根据第二触发电信号使得正常信号端子提供正常显示信号。
基于上述显示装置的结构可以发现，模式触发器1的输出端与模式控制器3的输入端连接，使得模式触发器1能够触发模式控制器3进行模式选择；而模式控制器3的输出端分别与信号切换器4的控制端和显示驱动器5的控制端连接，而信号切换器4的输出端分别与正常显示信号端子401，以及与数据存储器400相接的待机显示信号端子402连接，正常显示信号端子401和待机显示信号端子402分别与显示驱动器5的输入端连接，使得在需要进行正常显示时，通过模式触发器1向模式控制器3发送第一触发电信号，使得模式控制器3根据第一触发电信号控制显示驱动器5在需要进行待机显示时，通过模式控制器3控制信号切换器4使得待机显示信号端子402给显示驱动器5的提供待机显示信号，这样就能够在待机状态通过模式触发器触发待机显示模式，以显示数据储存器通过待机显示信号端子402所提供的 显示装置自带信息内容(如年月日)，而由于显示显示装置所自带的信息内容需要使得显示驱动器5驱动显示面板所有像素工作，因此，本公开提供的显示装置在待机状态下，只需要通过模式触发器1触发待机显示模式，减小显示装置显示自带信息时显示装置的功耗，以及显示装置的硬件损耗。
可以理解的是，上述实施例中数据存储器400可以为显示装置的内存，也可以是另外接入的数据存储器400，其与计时器连接，以存储计时器实时计算出的时间信息。当然，数据存储器400不仅限于存储显示装置所自带的信息，也可以在正常显示时，存储正常显示信号。
在一个实施例中，上述实施例中的显示控制器还包括触发识别器2，模式触发器1的输出端通过触发识别器2与模式控制器3的输入端连接，使得模式触发器1发出模式第一触发信号时，可通过触发识别器2进行触发信号的确认，保证所输入的第一触发信号的准确性和真实性。
下面结合图2和图3举例说明上述触发识别器2的具体实现结构，以及识别原理。
第一种实现结构如图2所示，上述触发识别器2包括计数继电器211和第一数值比较器212，模式触发器1为预设按键101；预设按键101与计数继电器211的输入端连接，第一数值比较器212的第一输入端与计数继电器211的输出端连接，第一数值比较器212的第二输入端与第一基准信号端子210连接，第一数值比较器212的输出端与模式控制器3的输入端连接。预设按键101开关可以为显示装置上的任意开关按键，也可以是另外接入的按键，也可以是显示装置中的“home”键。
此时，由于预设按键101与计数继电器211的输入端连接，而第一数值比较器212的第一输入端与计数继电器211的输出端连接，第一数值比较器212的第二输入端与第一基准信号端子210连接，第一数值比较器212的输出端与模式控制器3的输入端连接，使得计数继电器211可以识别预设按键101的按压次数，而第一数值比较器212则可以将计数继电器211所识别的预设按键101的按压次数，与第一基准信号端子210所提供的基准信号进行比较，以在预设按键101的按压次数等于基准信号时，发出第一触发电信号给模式控制器3，使得 模式控制器3控制显示面板处在待机显示模式，而在预设按键101的按压次数大于基准信号时，发出第二触发电信号给模式控制器3，使得模式控制控制显示面板处在正常显示模式。
第二种实现结构，如图3所示，上述实施例中触发识别器2包括角度识别器221和第二数值比较器，模式触发器1包括方向感应器102和预设按键101；方向感应器102的输出端与角度识别器221的输入端连接，第二数值比较器的第一输入端与所述角度识别器221的输出端连接，第二数值比较器的第二输入端与第二基准信号端子连接，第二数值比较器的输出端和预设按键101分别与模式控制器3的输入端连接；预设按键101开关可以为显示装置上的任意开关按键，也可以是另外接入的按键，也可以是显示装置中的“home”键。
此时，由于方向感应器102的输出端与角度识别器221的输入端连接，第二数值比较器的第一输入端与角度识别器221的输出端连接，第二数值比较器的第二输入端与第二基准信号端子220连接，第二数值比较器的输出端与模式控制器3的输入端连接，使得方向感应器102可以识别显示装置的方向，并通过角度识别器221识别显示装置所处的角度，然后利用第二数值比较器比较显示装置所处的角度与第二基准信号端子220所提供的基准信号，在相等的条件下，向模式控制器3提供第一触发电信号，使得模式控制器3控制显示面板处在待机显示模式，在预设按键101的按压次数大于基准信号的条件下，不会发出触发电信号，保持待机状态，至于模式控制器3控制显示面板处在待机显示模式的具体过程可参见前文描述。
而由于预设按键101与模式控制器3的输入端连接，使得在需要进行正常显示时，通过按压预设按键101向模式控制器3发出第二触发电信号，使得模式控制器3在接收到第二触发电信号后，模式控制器3控制显示面板处在正常显示模式，至于模式控制器3控制显示面板处在正常显示模式的过程参见前文描述。
在一个示例中，方向感应器102为三维陀螺仪或角速度传感器，角度识别器221为用于将角速度转换为旋转角度的角速度积分电路，以利用角速度积分电路将三维陀螺仪或角速度传感器所感测到的角速度转换为旋转角度。
第三种实现结构如图4所示，上述显示面板为触摸式显示面板， 模式触发器1为触摸检测器103和预设按键101，触发识别器2包括第一逻辑与门运算电路231以及用于检测触摸式显示面板显示面光线的光线传感器233，光线传感器233的输出端与所述第一逻辑与门运算电路231的第一输入端连接，触摸检测器103的输出端与第一逻辑与门运算电路231的第二输入端连接，第一逻辑与门运算电路231的输出端和预设按键101分别与模式控制器3的输入端连接；预设按键101开关可以为显示装置上的任意开关按键，也可以是另外接入的按键，也可以是显示装置中的“home”键。
此时，由于触摸检测器103的输出端与模式控制器3的输入端连接，在电极条件下，只需要通过触摸触摸式显示面板，使得触摸检测器103检测到触摸信号，并以第一触发电信号的形式发送给模式控制器3，使得模式控制器3控制触摸式显示面板处在待机显示模式；至于模式控制器3控制触摸式显示面板处在待机显示模式的过程参见前文描述。而由于预设按键101与模式控制器3的输入端连接，使得需要正常显示时，通过按压预设按键101，使得预设按键101发送第二触发电信号，模式控制器3在接收到第二触发电信号时，模式控制器3控制触摸式显示面板处在正常显示模块；至于模式控制器3控制触摸式显示面板处在正常显示模块的过程可参见前文描述。
另外，考虑到在特定情况下误触触摸式显示面板，如在手扶触摸式显示面板时，触摸式显示面板一直保持被触摸的状态，此时触摸式显示面板内部没有光线，因此，本公开实施例还引入了检测所述触摸式显示面板显示面光线的光线传感器233，且由于光线传感器233的输出端与第一逻辑与门运算电路231的输入端连接，触摸检测器103的输出端与第二逻辑与门运算电路232的输入端连接，第一逻辑与门运算电路231的输出端与模式控制器3的输入端连接，使得光线传感器233可检测触摸式显示面板的显示屏是否有光线；其中，第一逻辑与门运算电路231有电信号输出，表明光线传感器233检测到光线，触摸检测器103识别到触摸信息，此时可利用第一逻辑与门运算电路231所输出的电信号控制模式控制器3使得显示面板处在待机显示模式。
如果第一逻辑与门运算电路231没有电信号输出，且触摸检测器103检测到信息，则表明光线传感器233没有检测到光线，此时第一逻辑与门运算电路231无法控制模式控制器3使得显示面板处在待机显 示模式。
示例性的，如图4所示，上述实施例中的触摸检测器103为手势识别器或指纹识别器；触发识别器2还包括第二逻辑与门运算电路232，第二逻辑与门运算电路232的第一输入端与所述触摸检测器103的输出端连接，第二逻辑与门运算电路232的第二输入端与第三基准信号端子230连接；第二逻辑与门运算电路232的输出端与第一逻辑与门运算电路231的第二输入端连接。
当触摸检测器103为手势识别器时，通过第二逻辑与门运算电路232还能够判断触摸的手势是否与第三基准信号端子230所提供的预设手势信号相同，以在相同时向第一逻辑与门运算电路231输入第一触发电信号；而触摸检测器103为指纹识别器时，可通过第二逻辑与门运算电路232判断触摸的指纹是否与第三基准信号端子230所提供的预设指纹信号相同，以在相同时向第一逻辑与门运算电路231输入第一触发电信号。
此处需要说明的是，上述第三基准信号端子230可根据触摸检测器103的不同，选择与不同存储器连接。如触摸检测器103为手势识别器，则上述第三基准信号端子230与预设指纹存储器连接，以向第二逻辑与门运算电路232提供预设指纹信号；触摸检测器103为手势识别器，则上述第三基准信号端子230与预设手势存储器连接，以向第二逻辑与门运算电路232提供预设手势信号。
进一步，如图4所示，上述触发识别器2还包括触摸定位器234，触摸检测器103的输出端还与触摸定位器234的输入端连接，触摸定位器234的输出端与模式控制器3的输入端连接，以在进行待机显示时，使得模式控制器3接收触摸定位器234所发出的定位信息后，控制显示驱动器5驱动触摸式显示面板进行待机显示。
进一步，如图5所述，上述实施例中还可以根据触摸位置进行待机显示，如：当触摸到图5的圆弧区域时，待机显示所显示的内容就会显示该圆弧区域。
在一个实施例中，如图6所示，触摸式显示面板为触摸式液晶显示面板，触摸式液晶显示面板包括位于正常显示区域A内的待机显示区域；显示装置还包括背光模组，背光模组包括用于对应正常显示区域A的m个正常显示光源6；显示控制器还包括背光控制器8，背光 控制器8包括背光控制器81、电源82，以及与电源82连接的m个电源用电磁开关83，m个电源用电磁开关83与m个正常显示光源6一一对应连接；模式控制器3的输出端还与背光控制器81的输入端连接，背光控制器81的输出端分别与m个电源用电磁开关83的控制端连接。
具体实施时，模式控制器3将触摸位置信息发送给背光控制器81，使得背光控制器81控制对应触摸位置的电源用电磁开关闭合，以点亮这些电源用电磁开关对应的正常显示光源，从而使得显示面板对应触摸位置进行待机显示，将这些待机显示的区域定义为可变待机显示区域。
如图7所示，第一次触摸触摸式液晶显示面板时，图7被虚线框框出的正常显示光源被点亮，相应的在触摸式液晶显示面板上就具有第一可变待机显示区域B1，该第一可变待机显示区域B1与图7被虚线框框出的正常显示光源对应。
如图8所示，第二次触摸触摸式液晶显示面板时，图8被虚线框框出的正常显示光源被点亮，相应的在触摸式液晶显示面板上就具有第二可变待机显示区域B2，该第二可变待机显示区域B2与图8被虚线框框出的正常显示光源对应。
当然上述实施例提供的显示装置在实现待机显示时，也可以将待机显示的区域固定，将固定的待机显示区域称作固定待机显示区域B0(参见图10和图12)；此时，可通过以下两种结构实现。
第一种结构：如图9和图10所示，上述显示面板为液晶显示面板，液晶显示面板包括位于正常显示区域A的待机显示区域，将该待机显示区域称作固定待机显示区域B0；显示装置还包括背光模组，背光模组包括用于对应正常显示区域A的m个正常显示光源6；k个正常显示光源6a作为k个待机显示光源对应固定待机显示区域B0；显示控制器还包括背光控制器8，背光控制器8包括待机背光控制器812、电源82以及与电源82连接的m个电源用电磁开关83；m个正常显示光源6与m个电源用电磁开关83一一对应连接；1＜k＜m。
模式控制器3的输出端还分别与m个电源用电磁开关83的控制端和待机背光控制器812的输入端连接，待机背光控制器812的输出端分别与作为k个待机显示光源的k个正常显示光源6a对应的k个电源用电磁开关83a的控制端连接，使得模式控制器3接收到第一触发电 信号，模式控制器3控制待机背光控制器812向k个作为待机显示光源的正常显示光源对应的电源用电磁开关发出信号，使得作为k个待机显示光源的k个正常显示光源6a对应的k个电源用电磁开关83a闭合，从而点亮作为k个待机显示光源的k个正常显示光源6a，以实现固定待机显示区域B0中的待机显示；而在模式控制器3接收到第二触发电信号时，模式控制器3控制m个电源用电磁开关83闭合，使得m个正常显示光源6点亮，从而实现正常显示。
第二种结构：如图11-图13所示，上述显示面板为液晶显示面板，液晶显示面板包括位于正常显示区域A的待机显示区域，将该待机显示区域称作固定待机显示区域B0；显示装置还包括背光模组，背光模组包括导光膜片、用于对应正常显示区域A的m个正常显示光源6以及用于对应固定待机显示区域的k个待机显示光源7，m个正常显示光源位于导光膜片作为入光面的第一侧面，k个待机显示光源位于导光膜片的第二侧面。
示例性的，如图12和图13所示，k个待机显示光源7所在的导光膜片的第二侧面，可以与导光膜片的第一侧面相对，也可以相邻。
如图11所示，上述显示控制器还包括背光控制器8，背光控制器8包括待机背光控制器812和正常背光控制器811；模式控制器3的输出端分别与待机背光控制器812的控制端和正常背光控制器811的输入端连接；正常背光控制器811的输出端分别与m个正常显示光源连接，待机背光控制器812的输出端分别与k个待机显示光源连接；此时，模式控制器3接收到第一触发电信号时，模式控制器控制待机背光控制器812点亮k个待机显示光源7，以实现固定待机显示区域B0的待机显示；而模式控制器接收到第二触发电信号时，模式控制器控制正常背光控制器811点亮m个待机显示光源，以实现正常显示。
另外，上述实施例中待机背光控制器812和正常背光控制器811相当于电控开关，只需要在接收到对应信号后，点亮对应显示光源即可，无需特殊的方法改进。现有技术中如电磁开关就可以实现。
需要说明的是，上述实施例中信号切换器4的结果多种多样，下面给出一种具体结构，并说明其切换原理。
如图14所示，上述实施例中的信号切换器4包括待机显示用电磁开关42和正常显示用电磁开关41，待机显示用电磁开关42设在待机 显示信号端子402上，正常显示用电磁开关41设在正常显示信号端子401上，模式控制器3的输出端分别与待机显示用电磁开关42的控制端和正常显示用电磁开关41的控制端连接。
当模式控制器3接收到第一触发电信号时，模式控制器3控制待机显示用电磁开关42闭合，使得数据存储器400中存储的待机显示信号可通过待机显示信号端子402提供给显示驱动器5；当模式控制器3接收到第二触发电信号时，模式控制器3控制正常显示用电磁开关41闭合，使得正常显示信号可通过待机显示信号端子402提供给显示驱动器5。
上述显示驱动器5为现有显示驱动器，如图15所示，其包括时序控制器51、数据驱动器53和栅极驱动器52；显示面板至少包括阵列基板，阵列基板包括阵列化的薄膜晶体管；模式控制器3的输出端与时序控制器51的控制端连接，正常显示信号端子401和待机显示信号端子402分别与所述时序控制器51的输入端连接，时序控制器51的输出端分别与所述数据驱动器53的输入端和所述栅极驱动器52的输入端连接，数据驱动器53的输出端与阵列化的薄膜晶体管的信号输入端连接，栅极驱动器52的输出端与阵列化的薄膜晶体管的控制端连接。
在进行待机显示时，模式控制器3接收到第一触发电信号，控制时序控制器51，启动时序控制器51，使得时序控制器51接收待机数据信号，并传送给栅极驱动器52和数据驱动器53进行显示。在进行正常显示时，模式控制器3接收到第二触发电信号，控制时序控制器51，使得时序控制器51接收正常数据信号进行显示。
另外，上述栅极驱动器52为栅极驱动电路(GOA电路)时，栅极驱动电路制作在阵列基板上，且栅极驱动电路会依次打开阵列基板中每行薄膜晶体管，且不管是待机显示，还是正常显示，只是由于待机显示时，数据驱动器53只给固定几列数据线提供待机数据信号，因此，待机显示时，虽然栅极驱动电路会依次打开阵列基板中每行薄膜晶体管，但阵列基板中的薄膜晶体管并不是每个都会工作。
与现有技术相比，本公开提供的显示控制器和显示装置在待机状态下，只需要通过模式触发器触发待机显示模式，减小显示装置显示自带信息时显示装置的功耗以及显示装置的硬件损耗。
