具体实施方式
下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的要素。下面通过参考附图描述的实施例是示例性的,旨在用于解释本申请,而不能理解为对本申请的限制。
本申请实施例针对相关技术中,由于可折叠显示屏的尺寸较大,分辨率较高,使用单颗驱动芯片对显示屏进行驱动,无法有效驱动整个显示屏的问题,提出一种显示屏驱动方法。
本申请实施例提供的显示屏驱动电路,通过两个驱动芯片对整个显示屏进行驱动,且两个驱动芯片驱动的显示区域存在一部分的交叠区域(即第三显示区域),进而通过控制器根据显示屏的展开状态,确定第一驱动芯片与第二驱动芯片对显示屏的驱动方式,从而通过两个驱动芯片对显示屏进行驱动,提升了对显示屏的驱动能力,改善了显示屏的显示效果。
下面参考附图对本申请提供的显示屏驱动电路、方法、电子设备、存储介质及计算机程序进行详细描述。
图1为本申请实施例所提供的一种显示屏驱动电路的结构示意图。
如图1所示,该显示屏驱动电路10,包括:第一驱动芯片110、第二驱动芯片120及控制器130。
其中,第一驱动芯片110,与显示屏的第一扫描线组连接,以及与显示屏的第一显示区域对应的第一数据线组及显示屏的第三显示区域对应的第三数据线组连接。
第二驱动芯片120,与显示屏的第二扫描线组连接,以及与显示屏的第二显示区域对应的第二数据线组及第三数据线组连接,其中,第三显示区域位于第一显示区域与第二显示区域之间。
控制器130,分别与第一驱动芯片110及第二驱动芯片120连接,用于获取显示屏的展开状态,并根据显示屏的展开状态,控制第一驱动芯片110和/或第二驱动芯片120驱动显示屏进行显示。
需要说明的是,对于可折叠显示屏,由于显示屏的尺寸较大、分辨率较高,而单颗驱动芯片由于驱动能力有限,无法有效驱动整个显示屏。因此,在本申请实施例中,可以采用两个驱动芯片对显示屏进行驱动。
在本申请实施例中,控制器130可以是显示屏所在的电子设备中的处理器,也可以是为了实现对显示屏的驱动,专门设置的微处理器,本申请实施例对此不做限定。
作为一种可能的实现方式,可以将整块显示屏的显示区域划分为第一显示区域、第二显示区域与第三显示区域,且第三显示区域位于第一显示区域与第二显示区域之间。其中,第一显示区域可以由第一驱动芯片110驱动,第二显示区域可以由第二驱动芯片120驱动,第三显示区域既可以由第一驱动芯片110驱动,也可以由第二驱动芯片120驱动。也就是说,第一驱动芯片110驱动的显示区域可以为第一显示区域与第三显示区域,第二驱动芯片120驱动的显示区域可以为第二显示区域与第三显示区域。
如图1所示,在实际连接时,第一驱动芯片110可以与位于显示屏的一侧的第一扫描线组(Gate线)连接,即与图1中位于第一显示区域左侧的Gate1至GateN连接,第二驱动芯片120可以与位于 显示屏的另一侧的第二扫描线组(Gate线)连接,即与图1中位于第二显示区域右侧的Gate1至GateN连接;第一驱动芯片110与第一显示区域对应的第一数据线组(Source线)及第三显示区域对应的第三数据线组连接,即与图1中的S11至S1M连接;第二驱动芯片120与第二显示区域对应的第二数据线组及第三数据线组连接,即与图1中的S21至S2M连接,从而使得第一驱动芯片110与第二驱动芯片120均可以对第三显示区域进行驱动。
需要说明的是,若显示屏中包括N行像素,则第一扫描线组中可以包括N个扫描线,第二扫描线组中可以包括N个扫描线;其中,显示屏中第i行像素中的每个像素点对应的开关的栅极与第一扫描线组中的第i个扫描线连接,以及与第二扫描线组中的第i个扫描线连接,i为小于或等于N的正整数。也就是说,对于显示屏中的每行像素,可以在该行像素的两端分别引出一个扫描线,以构成第一扫描组与第二扫描线组。
在本申请实施例中,显示屏所处的展开状态不同,可以采用不同的的驱动芯片驱动显示屏进行显示。因此,控制器130可以获取显示屏的展开状态,并根据显示屏的展开状态,控制第一驱动芯片110与第二驱动芯片120同时驱动显示屏进行显示,或者驱动第一驱动芯片110与第二驱动芯片120中的任一个驱动显示屏进行显示。
作为一种可能的实现方式,显示屏的折叠线可以位于第三显示区域内,以使显示屏处于折叠状态时,可以仅通过一个驱动芯片对显示屏进行驱动,即可以满足用户的使用需求。
举例来说,折叠线可以为显示屏的中线,显示屏的面积为N,其中,N为正整数,则第一显示区域与第三显示区域的面积之和可以大于N/2,第二显示区域与第三显示区域的的面积之和也可以大于N/2。
需要说明的是,第一显示区域、第二显示区域及第三显示区域的具体大小,可以根据第一驱动芯片110与第二驱动芯片120的驱动能力确定,各驱动芯片的驱动范围可以分别根据实际显示需求,在各驱动芯片的最大驱动范围内调整。
作为一种可能的实现方式,在显示屏处于展开状态时,通常需要整个显示屏都处于工作状态,从而可以通过第一驱动芯片110与第二驱动芯片120共同驱动显示屏进行显示。因此,可以在驱动显示屏进行显示之前,控制器130可以首先判断显示屏是否处于展开状态,进而根据判断结果,确定对显示屏的驱动策略。即在本申请实施例一种可能的实现形式中,在显示屏的折叠线位于第三显示区域内时,控制器130,还可以用于:
获取第一显示区域与第二显示区域之间的夹角;
若第一显示区域与第二显示区域之间的夹角处于预设范围,则确定显示屏处于展开状态;
若第一显示区域与第二显示区域之间的夹角未处于预设范围,则确定显示屏未处于展开状态。
在本申请实施例中,由于第一显示区域与第二显示区域处于显示屏折叠线的两侧,从而控制器130可以根据第一显示区域与第二显示区域之间的夹角,确定显示屏是否处于展开状态。
具体的,可以预设显示屏处于展开状态时的角度范围,从而控制器130可以获取第一显示区域与第二显示区域之间的夹角,进而在第一显示区域与第二显示区域之间的夹角处于预设范围时,确定显示屏处于展开状态;否则,确定显示屏未处于展开状态。
需要说明的是,由于显示屏处于展开状态时,第一显示区域与第二显示区域处于同一平面或近似处于同一平面,从而可以将预设范围确定为[170°,180°],即在第一显示区域与第二显示区域的夹角处于[0,170°)范围时,可以确定显示屏未处于展开状态;或者,还可以将预设范围确定为[180°,190°],即在第一显示区域与第二显示区域的夹角处于(190°,360°]范围时,可以确定显示屏未处于展开状态。
需要说明的是,上述170°与190°仅为示例性的,不能视为对本申请的限制。实际使用时,可以根据实际需要及具体的应用场景,确定具体的预设范围,本申请实施例对此不做限定。
进一步的,在显示屏处于展开状态时,通常需要整个显示屏都处于工作状态,从而可以通过第一驱动芯片110与第二驱动芯片120共同驱动显示屏进行显示。即在本申请实施例一种可能的实现形式中,在显示屏处于展开状态时,控制器130,具体可以用于:
控制第一驱动芯片110向第一扫描线组发送第一时序信号,以及控制第二驱动芯片120向第二扫描线组发送第二时序信号,以通过第一扫描线组与第二扫描线组导通显示屏中每个像素点对应的开关的栅极,其中,第一时序信号与第二时序信号为同步时序信号;
若当前的显示帧为奇数帧,则控制第一驱动芯片110与第一数据线组及第三数据线组导通,以及控制第二驱动芯片120与第二数据线组导通,以驱动显示屏对当前的显示帧进行显示;以及
若当前的显示帧为偶数帧,则控制所述第一驱动芯片110与第一数据线组导通,以及控制第二驱动芯片120与第二数据线组及第三数据线组导通,以驱动显示屏对当前的显示帧进行显示。
在本申请实施例中,由于显示屏处于展开状态时,可以通过两个驱动芯片对显示屏进行驱动,而两个驱动芯片所驱动的显示区域的交界处都无法获得相邻区域的亮度信息,从而无法实现像素增强补偿,导致交界处的亮度差异较大,视觉体验较差。因此,在本申请实施例中,显示屏处于展开状态时,可以采用插帧的方式,使得第一驱动芯片110与第二驱动芯片120交替驱动第三显示区域进行显示,以使第一驱动芯片110所驱动的显示区域与第二驱动芯片120所驱动的显示区域的交界处不断交替变换,从而使得两个驱动芯片所驱动的显示区域不存在固定的交界处,使得人眼不易感知交界处的光学差异,以提升显示屏的视觉舒适度。
作为一种可能的实现方式,在显示屏处于展开状态时,可以通过第一驱动芯片110与第二驱动芯片120共同驱动显示屏进行显示,从而控制器130可以控制第一驱动芯片110向第一扫描线组发送第一时序信号,以及控制第二驱动芯片120向第二扫描线组发送第二时序信号,以使第一驱动芯片110与第二驱动芯片120共同驱动显示屏中每个像素点对应的开关的栅极打开,并准备根据驱动芯片通过数据线发送的数据进行显示。
在本申请实施例中,通过第一驱动芯片110与第二驱动芯片120共同驱动显示屏中每个像素点对应的开关的栅极打开之后,可以根据当前的显示帧的显示次序,确定对当前的显示帧的显示策略。具体的,可以在每次控制第一驱动芯片110与第二驱动芯片120通过数据线发送显示数据,以驱动显示屏对当前的显示帧进行显示之前,通过控制器130首先判断当前的显示帧是否为奇数帧,即当前的显示帧的显示次序是否为奇数。在当前的显示帧为奇数帧时,可以利用第一驱动芯片110驱动第三显示区域进行显示;在当前的显示帧为偶数帧时,可以利用第二驱动芯片120驱动第三显示区域进行显示。
举例来说,显示屏在2020年5月1日13点10分30秒开始显示第一帧图像,当前的显示帧为显示屏在该时刻进行显示之后,显示的第15帧显示帧,从而可以确定当前的显示帧为奇数帧。
在本申请实施例中,确定当前的显示帧为奇数帧时,可以利用第一驱动芯片110驱动第一显示区域与第三显示区域进行显示,以及利用第二驱动芯片120驱动第二显示区域进行显示,从而可以控制第一驱动芯片110与第一显示区域对应的第一数据线组及第三显示区域对应第三数据线组导通,以及控制第二驱动芯片120与第二显示区域对应的第二数据线组导通,以使第一驱动芯片110通过第一数据线组与第三数据线组,向显示屏发送显示数据(每个像素点的亮度、颜色等数据),以及使得第二驱动芯片120通过第二数据线组,向显示屏发送显示数据,从而使得第一显示区域与第三显示区域对当前的显示帧的一部分区域进行显示,以及使得第二显示区域对当前的显示帧的其余部分进行显示,进而实现对当前显示帧的完整显示。
在本申请实施例中,确定当前的显示帧为偶数帧时,可以利用第一驱动芯片110驱动第一显示区域进行显示,以及利用第二驱动芯片120驱动第二显示区域与第三显示区域进行显示,从而可以控制第一驱动芯片110与第一数据线组导通,以及控制第二驱动芯片120与第二数据线组及第三数据线组导通,以使第一驱动芯片110通过第一数据线组,向显示屏发送显示数据,以及使得第二驱动芯片120通过第二数据线组及第三数据线组,向显示屏发送显示数据,从而使得第一显示区域对当前的显示帧的一部分区域进行显示,以及使得第二显示区域与第三显示区域对当前的显示帧的其余部分进行显示,进而实现对当前显示帧的完整显示。
进一步的,第一驱动芯片110及第二驱动芯片120还可以通过开关电路与第三数据线组连接,以便于实现第一驱动芯片110与第二驱动芯片120对第三显示区域的交替驱动。即在本申请实施例一种 可能的实现形式中,如图2所示,上述显示屏驱动电路10,还可以包括第一开关电路111与第二开关电路121。
其中,第一驱动芯片110通过第一开关电路111与第三数据线组连接;第二驱动芯片120通过第二开关电路121与第三数据线组连接。
作为一种可能的实现方式,开关电路可以是驱动芯片的内部开关电路,即第一开关电路111可以位于第一驱动芯片110内部,第二开关电路121可以位于第二驱动芯片120内部。
进一步的,第一驱动芯片110及第二驱动芯片120通过开关电路与第三数据线组连接时,控制器130可以通过控制第一开关电路111与第二开关电路121的导通状态,实现第一驱动芯片110与第二驱动芯片120对第三显示区域的交替驱动。即在本申请实施例一种可能的实现形式中,控制器130,还可以用于:
若当前的显示帧为奇数帧,则控制第一开关电路111导通,以使第一驱动芯片110与第一数据线组及第三数据线组导通,以及控制第二开关电路121断开,以使第二驱动芯片120仅与第二数据线组导通,以驱动显示屏对当前的显示帧进行显示;
若当前的显示帧为偶数帧,则控制第一开关电路111断开,以使第一驱动芯片110仅与第一数据线组导通,以及控制第二开关电路121导通,以使第二驱动芯片120与第二数据线组及第三数据线组导通,以驱动显示屏对当前的显示帧进行显示。
作为一种可能的实现方式,通过开关电路实现第一驱动芯片110及第二驱动芯片120与第三显示区域的数据线的连接时,在通过第一驱动芯片110驱动第三显示区域时,控制器130可以控制第一驱动芯片110与第三数据线组之间的第一开关电路导通,以及控制第二驱动芯片120与第三数据线组之间的第二开关电路121断开,从而使得第一驱动芯片110可以对第一显示区域与第三显示区域进行驱动,而第二驱动芯片120仅可以对第二显示区域进行驱动,以驱动显示屏对当前的显示帧进行完整显示。
相应的,在通过第二驱动芯片120驱动第三显示区域时,控制器130可以控制第二驱动芯片120与第三数据线组之间的第二开关电路121导通,以及控制第一驱动芯片与第三数据线组之间的第一开关电路111断开,从而使得第二驱动芯片120可以对第二显示区域与第三显示区域进行驱动,而第一驱动芯片110仅可以对第一显示区域进行驱动,以驱动显示屏对当前的显示帧进行完整显示。
本申请实施例提供的显示屏驱动电路,通过两个驱动芯片对整个显示屏进行驱动,且两个驱动芯片驱动的显示区域存在一部分的交叠区域(即第三显示区域),进而通过控制器根据显示屏的展开状态,确定第一驱动芯片与第二驱动芯片对显示屏的驱动方式,从而通过两个驱动芯片对显示屏进行驱动,提升了对显示屏的驱动能力,改善了显示屏的显示效果。
需要说明的是,在显示屏处于展开状态时,本申请实施例的显示屏驱动电路通过两个驱动芯片对整个显示屏进行驱动,且两个驱动芯片驱动的显示区域存在一部分的交叠区域(即第三显示区域),进而使得两个驱动芯片交替驱动第三显示区域进行显示,以使两个驱动芯片所驱动的显示区域的交界处不断交替变换,从而不仅通过两个驱动芯片提升了对显示屏的驱动能力,而且使得两个驱动芯片所驱动的显示区域不存在固定的交界处,使得人眼不易感知交界处的光学差异,提升了显示屏的视觉舒适度。
在本申请一种可能的实现形式中,显示屏未处于展开状态时,可以根据用户当前使用的显示区域,选择其中一个驱动芯片对显示屏进行驱动,以进一步提升显示屏的显示效果,并降低电子设备的功耗。
下面结合图1和图2,对本申请实施例提供的显示屏驱动电路进行进一步说明。
在上述实施例的基础上,在显示屏的折叠线位于所述第三显示区域内,且在显示屏未处于展开状态时,控制器130,具体用于:
控制第一驱动芯片110向第一扫描线组发送第一时序信号,以通过第一扫描线组导通显示屏中每个像素点对应的开关的栅极;
控制第一驱动芯片110与第一数据线组及第三数据线组导通,并关闭第二驱动芯片120,以驱动显 示屏对当前的显示帧进行显示;
或者

控制第二驱动芯片120与第二数据线组及第三数据线组导通,并关闭第一驱动芯片110,以驱动显示屏对当前的显示帧进行显示。
在本申请实施例中,若控制器130确定显示屏未处于展开状态,如处于折叠状态、支撑状态等,则可以根据用户当前使用的显示区域,确定对显示屏的驱动策略。具体的,控制器130若确定用户当前使用的显示区域为第一显示区域所在的显示区域,则可以控制第一驱动芯片110向第一扫描线组发送第一时序信号,以使第一驱动芯片110驱动显示屏中每个像素点对应的开关的栅极打开;之后,控制第一驱动芯片110与第一数据线组及第三数据线组导通,以使第一驱动芯片110通过第一数据线组与第三数据线组,向显示屏发送显示数据,即利用第一驱动芯片110驱动第一显示区域与第三显示区域,对当前的显示帧进行显示;并且,可以关闭第二驱动芯片120(比如断开第二驱动芯片120的供电通路),以使第二显示区域处于休眠状态,以节约电子设备的功耗。
相应的,若控制器130确定用户当前使用的显示区域为第二显示区域所在的显示区域,则可以控制第二驱动芯片120向第二扫描线组发送第二时序信号,以使第二驱动芯片120驱动显示屏中每个像素点对应的开关的栅极打开;之后,可以控制第二驱动芯片120与第二数据线组及第三数据线组导通,以使第二驱动芯片120通过第二数据线组与第三数据线组,向显示屏发送显示数据,即利用第二驱动芯片120驱动第二显示区域与第三显示区域,对当前的显示帧进行显示;并且,可以关闭第一驱动芯片110(比如断开第一驱动芯片110的供电通路),以使第一显示区域处于休眠状态。
作为一种可能的实现方式,在显示屏所在的电子设备中包括摄像头时,可以在显示屏未处于展开状态时,根据电子设备中摄像头采集的图像,确定用户当前使用的显示区域。即在本申请实施例一种可能的实现方式中,上述显示屏所在的电子设备中可以包括摄像头;相应的,控制器130,还可以用于:

可选地,若第一显示区域包括摄像头,则控制器130可以在摄像头采集的参考图像中包括用户人脸时,确定用户当前注视第一显示区域;相应的,若摄像头采集的参考图像中未包含用户人脸,则控制器130可以确定用户当前注视第二显示区域。
可选的,若第二显示区域包括摄像头,则控制器130可以在摄像头采集的参考图像中包括用户人脸时,确定用户当前注视第二显示区域;相应的,若摄像头采集的参考图像中未包含用户人脸,则控制器130可以确定用户当前注视第一显示区域。

相应的,控制器130在确定用户当前注视第二显示区域时,可以控制第二驱动芯片120向第二扫描线组发送第二时序信号,以使第二驱动芯片120驱动显示屏中每个像素点对应的开关的栅极打开;之后,可以控制第二驱动芯片120与第二数据线组及第三数据线组导通,以使第二驱动芯片120通过第二数据线组与第三数据线组,向显示屏发送显示数据,即利用第二驱动芯片120驱动第二显示区域与第三显示区域,对当前的显示帧进行显示;并且,可以关闭第一驱动芯片110,以使第一显示区域处于休眠状态。
作为另一种可能的实现方式,在显示屏未处于展开状态时,还可以根据用户对显示屏的触摸情况,确定用户当前使用的显示区域。即在本申请实施例一种可能的实现方式中,控制器130,还可以用于:
获取用户手指与第一显示区域的第一接触面积,及与第二显示区域的第二接触面积;
在第一接触面积小于第二接触面积时,控制第一驱动芯片110向第一扫描线组发送第一时序信号,以通过第一扫描线组导通显示屏中每个像素点对应的开关的栅极;
控制第一驱动芯片110与第一数据线组及第三数据线组导通,并关闭第二驱动芯片120,以驱动显示屏对当前的显示帧进行显示;
在第一接触面积大于第二接触面积时,控制第二驱动芯片120向第二扫描线组发送第二时序信号,以通过第二扫描线组导通显示屏中每个像素点对应的开关的栅极;
控制第二驱动芯片120与第二数据线组及第三数据线组导通,并关闭第一驱动芯片110,以驱动显示屏对当前的显示帧进行显示。
在申请实施例中,确定显示屏未处于展开状态时,控制器130还可以通过显示屏中的触控单元获取用户手指对显示屏的触摸情况,以根据用户手指对显示屏的触摸情况,确定用户当前使用的显示区域,进而根据用户当前使用的显示区域,确定对显示屏的驱动策略。
可选地,在显示屏未处于展开状态,如电子设备处于折叠状态时,若用户手持电子设备,则用户当前未使用的显示区域与用户手指的接触面积通常较大。因此,控制器130可以获取用户手指与第一显示区域的第一接触面积,以及与第二显示区域的第二接触面积。若第一接触面积小于第二接触面积,则可以确定用户当前使用的显示区域为第一显示区域,从而控制器130可以控制第一驱动芯片110向第一扫描线组发送第一时序信号,以使第一驱动芯片110驱动显示屏中每个像素点对应的开关的栅极打开;之后,控制第一驱动芯片110与第一数据线组及第三数据线组导通,以使第一驱动芯片110通过第一数据线组与第三数据线组,向显示屏发送显示数据,即利用第一驱动芯片110驱动第一显示区域与第三显示区域,对当前的显示帧进行显示;并且,可以关闭第二驱动芯片120,以使第二显示区域处于休眠状态,以节约电子设备的功耗。
相应的,若第一接触面积大于第二接触面积,则可以确定用户当前使用的显示区域为第二显示区域,从而控制器130可以控制第二驱动芯片120向第二扫描线组发送第二时序信号,以使第二驱动芯片120驱动显示屏中每个像素点对应的开关的栅极打开;之后,可以控制第二驱动芯片120与第二数据线组及第三数据线组导通,以使第二驱动芯片120通过第二数据线组与第三数据线组,向显示屏发送显示数据,即利用第二驱动芯片120驱动第二显示区域与第三显示区域,对当前的显示帧进行显示;并且,可以关闭第一驱动芯片110,以使第一显示区域处于休眠状态。
可选地,在显示屏未处于展开状态且用户手持电子设备,则用户当前未使用的显示区域与用户手 指的接触点的数量通常较多,从而还可以根据用户手指与显示屏各区域的接触点的数量,确定用户当前使用的显示区域。因此,控制器130可以获取用户手指与第一显示区域的第一接触点数量,以及与第二显示区域的第二接触点数量。若第一接触点数量小于第二接触点数量,则可以确定用户当前使用的显示区域为第一显示区域;相应的,若第一接触点数量大于第二接触点数量,则可以确定用户当前使用的显示区域为第二显示区域。
可选地,在显示屏未处于展开状态且用户未手持电子设备时,还可以根据用户对显示屏的操作区域,确定用户当前使用的显示区域。从而控制器130可以获取用户对显示屏的触摸操作,以确定用户的触摸操作所在的操作区域,若用户的触摸操作所在的操作区域为第一显示区域,则可以确定用户当前使用的显示区域为第一显示区域;相应的,若用户的触摸操作所在的操作区域为第二显示区域,则可以确定用户当前使用的显示区域为第二显示区域。
需要说明的是,确定出用户当前使用的显示区域之后,可以按照上述方式确定对显示屏的驱动策略,具体实现过程及原理,可以参照上述实施例的详细描述,此处不再赘述。
本申请实施例提供的显示屏驱动电路,通过在显示屏处于展开状态时,通过两个驱动芯片交替驱动第三显示区区域,以及在显示屏未处于展开状态时,根据显示屏所在的电子设备中的摄像头采集的参考图像,或用户手指对显示屏的触摸情况,确定用户当前使用的显示区域,进而根据用户当前使用的显示区域,选择一个驱动芯片对显示屏进行驱动。由此,通过使得两个驱动芯片交替驱动第三显示区域进行显示,以使两个驱动芯片所驱动的显示区域的交界处不断交替变换,并且在显示屏未处于展开状态时,选择一个驱动芯片对显示屏进行驱动,从而不仅通过两个驱动芯片提升了对显示屏的驱动能力,使得两个驱动芯片所驱动的显示区域不存在固定的交界处,使得人眼不易感知交界处的光学差异,而且可以实现显示屏处于折叠状态时的瀑布屏效果,进一步提升了显示屏的显示效果和视觉舒适度,并且降低了显示屏处于折叠状态时电子设备的功耗。
为实现上述实施例,本申请还提出一种显示屏驱动方法。
图3为本申请实施例所提供的一种显示屏驱动方法的流程示意图。
如图3所示,该显示屏驱动方法,包括以下步骤:
步骤101,获取显示屏的展开状态,其中,显示屏为可折叠显示屏。
需要说明的是,对于可折叠显示屏,由于显示屏的尺寸较大、分辨率较高,而单颗驱动芯片由于驱动能力有限,无法有效驱动整个显示屏。因此,在本申请实施例中,可以采用两个驱动芯片对显示屏进行驱动。
作为一种可能的实现方式,可以将整块显示屏的显示区域划分为第一显示区域、第二显示区域与第三显示区域,且第三显示区域位于第一显示区域与第二显示区域之间。其中,第一显示区域可以由第一驱动芯片驱动,第二显示区域可以由第二驱动芯片驱动,第三显示区域既可以由第一驱动芯片驱动,也可以由第二驱动芯片驱动。也就是说,第一驱动芯片驱动的显示区域可以为第一显示区域与第三显示区域,第二驱动芯片驱动的显示区域可以为第二显示区域与第三显示区域。
如图1所示,在实际连接时,第一驱动芯片110可以与位于显示屏的一侧的第一扫描线组连接,即与图1中位于第一显示区域左侧的Gate1至GateN连接,第二驱动芯片120可以与位于显示屏的另一侧的第二扫描线组连接,即与图1中位于第二显示区域右侧的Gate1至GateN连接;第一驱动芯片110与第一显示区域对应的第一数据线组及第三显示区域对应的第三数据线组连接,即与图1中的S11至S1M连接;第二驱动芯片120与第二显示区域对应的第二数据线组及第三数据线组连接,即与图1中的S21至S2M连接,从而使得第一驱动芯片110与第二驱动芯片120均可以对第三显示区域进行驱动。
作为一种可能的实现方式,显示屏的折叠线可以位于第三显示区域内,以使显示屏处于折叠状态时,可以仅通过一个驱动芯片对显示屏进行驱动,即可以满足用户的使用需求。
举例来说,折叠线可以为显示屏的中线,显示屏的面积为N,其中,N为正整数,则第一显示区域与第三显示区域的面积之和可以大于N/2,第二显示区域与第三显示区域的的面积之和也可以大于 N/2。
需要说明的是,第一显示区域、第二显示区域及第三显示区域的具体大小,可以根据第一驱动芯片与第二驱动芯片的驱动能力确定,各驱动芯片的驱动范围可以分别根据实际显示需求,在各驱动芯片的最大驱动范围内调整。
在本申请实施例中,显示屏处于展开状态时,通常需要整个显示屏都处于工作状态,从而可以通过第一驱动芯片与第二驱动芯片共同驱动显示屏进行显示。因此,可以在驱动显示屏进行显示之前,首先判断显示屏是否处于展开状态,进而根据判断结果,确定对显示屏的驱动策略。
进一步的,可以根据第一显示区域与第二显示区域之间的夹角,获取显示屏的展开状态。即在本申请实施例一种可能的实现形式中,上述步骤101,可以包括:
获取第一显示区域与第二显示区域之间的夹角;
若第一显示区域与第二显示区域之间的夹角处于预设范围,则确定显示屏处于展开状态;
若第一显示区域与第二显示区域之间的夹角处于预设范围,则确定显示屏未处于展开状态。
在本申请实施例中,由于第一显示区域与第二显示区域处于显示屏折叠线的两侧,从而可以根据第一显示区域与第二显示区域之间的夹角,确定显示屏是否处于展开状态。
具体的,可以预设显示屏处于展开状态时的角度范围,从而可以获取第一显示区域与第二显示区域之间的夹角,进而在第一显示区域与第二显示区域之间的夹角处于预设范围时,确定显示屏处于展开状态;否则,确定显示屏未处于展开状态。
需要说明的是,由于显示屏处于展开状态时,第一显示区域与第二显示区域处于同一平面或近似处于同一平面,从而可以将预设范围确定为[170°,180°],即在第一显示区域与第二显示区域的夹角处于[0,170°)范围时,可以确定显示屏未处于展开状态;或者,还可以将预设范围确定为[180°,190°],即在第一显示区域与第二显示区域的夹角处于(190°,360°]范围时,可以确定显示屏未处于展开状态。
需要说明的是,上述170°与190°仅为示例性的,不能视为对本申请的限制。实际使用时,可以根据实际需要及具体的应用场景,确定具体的预设范围,本申请实施例对此不做限定。
步骤102,根据显示屏的展开状态,控制第一驱动芯片和/或第二驱动芯片驱动显示屏进行显示。
在本申请实施例中,显示屏所处的展开状态不同,可以采用不同的的驱动芯片驱动显示屏进行显示。因此,可以获取显示屏的展开状态,并根据显示屏的展开状态,控制第一驱动芯片与第二驱动芯片同时驱动显示屏进行显示,或者驱动第一驱动芯片与第二驱动芯片中的任一个驱动显示屏进行显示。
本申请实施例提供的显示屏驱动方法,通过两个驱动芯片对整个显示屏进行驱动,且两个驱动芯片驱动的显示区域存在一部分的交叠区域(即第三显示区域),进而通过控制器根据显示屏的展开状态,确定第一驱动芯片与第二驱动芯片对显示屏的驱动方式,从而通过两个驱动芯片对显示屏进行驱动,提升了对显示屏的驱动能力,改善了显示屏的显示效果。
在本申请一种可能的实现形式中,显示屏处于展开状态时,可以采用插帧的方式,使得第一驱动芯片与第二驱动芯片交替驱动第三显示区域进行显示,以使第一驱动芯片所驱动的显示区域与第二驱动芯片所驱动的显示区域的交界处不断交替变换,从而使得两个驱动芯片所驱动的显示区域不存在固定的交界处,使得人眼不易感知交界处的光学差异,以提升显示屏的视觉舒适度。
图4为本申请实施例所提供的另一种显示屏驱动方法的流程示意图。
如图4所示,该显示屏驱动方法,包括以下步骤:
步骤201,获取显示屏的展开状态,,其中,显示屏为可折叠显示屏,显示屏包括第一显示区域、第二显示区域及第三显示区域,第三显示区域位于第一显示区域与第二显示区域之间。
上述步骤201的具体实现过程及原理,可以参照上述实施例的详细描述,此处不再赘述。
步骤202,在显示屏处于展开状态时,控制第一驱动芯片向显示屏的第一扫描线组发送第一时序信号,以及控制第二驱动芯片向显示屏的第二扫描线组发送第二时序信号,以通过第一扫描线组与第二扫描线组导通显示屏中每个像素点对应的开关的栅极,其中,第一时序信号与第二时序信号为同步时序信号。
在本申请实施例中,由于显示屏处于展开状态时,可以通过两个驱动芯片对显示屏进行驱动,而两个驱动芯片所驱动的显示区域的交界处都无法获得相邻区域的亮度信息,从而无法实现像素增强补偿,导致交界处的亮度差异较大,视觉体验较差。因此,在本申请实施例中,显示屏处于展开状态时,可以采用插帧的方式,使得第一驱动芯片与第二驱动芯片交替驱动第三显示区域进行显示,以使第一驱动芯片所驱动的显示区域与第二驱动芯片所驱动的显示区域的交界处不断交替变换,从而使得两个驱动芯片所驱动的显示区域不存在固定的交界处,使得人眼不易感知交界处的光学差异,以提升显示屏的视觉舒适度。
作为一种可能的实现方式,在显示屏处于展开状态时,可以通过第一驱动芯片与第二驱动芯片共同驱动显示屏进行显示,从而控制器可以控制第一驱动芯片向第一扫描线组发送第一时序信号,以及控制第二驱动芯片向第二扫描线组发送第二时序信号,以使第一驱动芯片与第二驱动芯片共同驱动显示屏中每个像素点对应的开关的栅极打开,并准备根据驱动芯片通过数据线发送的数据进行显示。
步骤203,若当前的显示帧为奇数帧,则控制第一驱动芯片与第一显示区域对应的第一数据线组及第三显示区域对应的第三数据线组导通,以及控制第二驱动芯片与第二显示区域对应的第二数据线组导通,以驱动显示屏对当前的显示帧进行显示。
作为一种可能的实现方式,通过第一驱动芯片与第二驱动芯片共同驱动显示屏中每个像素点对应的开关的栅极打开之后,可以根据当前的显示帧的显示次序,确定对当前的显示帧的显示策略。具体的,可以在每次控制第一驱动芯片与第二驱动芯片通过数据线发送显示数据,以驱动显示屏对当前的显示帧进行显示之前,通过控制器首先判断当前的显示帧是否为奇数帧,即当前的显示帧的显示次序是否为奇数。在当前的显示帧为奇数帧时,可以利用第一驱动芯片驱动第三显示区域进行显示;在当前的显示帧为偶数帧时,可以利用第二驱动芯片驱动第三显示区域进行显示。
举例来说,显示屏在2020年5月1日13点10分30秒开始显示第一帧图像,当前的显示帧为显示屏在该时刻进行显示之后,显示的第15帧显示帧,从而可以确定当前的显示帧为奇数帧。
在本申请实施例中,确定当前的显示帧为奇数帧时,可以利用第一驱动芯片驱动第一显示区域与第三显示区域进行显示,以及利用第二驱动芯片驱动第二显示区域进行显示,从而可以控制第一驱动芯片与第一显示区域对应的第一数据线组及第三显示区域对应的第三数据线组导通,以及控制第二驱动芯片与第二显示区域对应的第二数据线组导通,以使第一驱动芯片通过第一数据线组与第三数据线组,向显示屏发送显示数据(每个像素点的亮度、颜色等数据),以及使得第二驱动芯片通过第二数据线组,向显示屏发送显示数据,从而使得第一显示区域与第三显示区域对当前的显示帧的一部分区域进行显示,以及使得第二显示区域对当前的显示帧的其余部分进行显示,进而实现对当前显示帧的完整显示。
进一步的,第一驱动芯片及第二驱动芯片还可以通过开关电路与第三显示区域的Source线连接,以便于实现第一驱动芯片与第二驱动芯片对第三显示区域的交替驱动。即在本申请实施例一种可能的实现形式中,上述第一驱动芯片通过第一开关电路与第三数据线组连接,第二驱动芯片通过第二开关电路与第三数据线组连接;相应的,上述步骤203,可以包括:
控制第一开关电路导通,以使第一驱动芯片与第一数据线组及第三数据线组导通,以及控制第二开关电路断开,以使第二驱动芯片仅与第二数据线组导通,以驱动显示屏对当前的显示帧进行显示。
作为一种可能的实现方式,通过开关电路实现第一驱动芯片及第二驱动芯片与第三显示区域的数据线的连接时,可以在通过第一驱动芯片驱动第三显示区域时,控制第一驱动芯片与第三数据线组之间的第一开关电路导通,以及控制第二驱动芯片与第三数据线组之间的第二开关电路断开,从而使得第一驱动芯片可以对第一显示区域与第三显示区域进行驱动,而第二驱动芯片仅可以对第二显示区域进行驱动,以驱动显示屏对当前的显示帧进行完整显示。
步骤204,若当前的显示帧为偶数帧,则控制第一驱动芯片与第一数据线组导通,以及控制第二驱动芯片与第二数据线组及第三数据线组导通,以驱动显示屏对当前的显示帧进行显示。
在本申请实施例中,确定当前的显示帧为偶数帧时,可以利用第一驱动芯片驱动第一显示区域进 行显示,以及利用第二驱动芯片驱动第二显示区域与第三显示区域进行显示,从而可以控制第一驱动芯片与第一数据线组导通,以及控制第二驱动芯片与第二数据线组及第三数据线组导通,以使第一驱动芯片通过第一数据线组,向显示屏发送显示数据,以及使得第二驱动芯片通过第二数据线组及第三数据线组,向显示屏发送显示数据,从而使得第一显示区域对当前的显示帧的一部分区域进行显示,以及使得第二显示区域与第三显示区域对当前的显示帧的其余部分进行显示,进而实现对当前显示帧的完整显示。
进一步的,第一驱动芯片及第二驱动芯片还可以通过开关电路与第三数据线组连接,以便于实现第一驱动芯片与第二驱动芯片对第三显示区域的交替驱动。即在本申请实施例一种可能的实现形式中,上述第一驱动芯片通过第一开关电路与第三数据线组连接,第二驱动芯片通过第二开关电路与第三数据线组连接;相应的,上述步骤204,可以包括:
控制第一开关电路断开,以使第一驱动芯片仅与第一数据线组导通,以及控制第二开关电路导通,以使第二驱动芯片与第二数据线组及第三数据线组导通,以驱动显示屏对当前的显示帧进行显示。
作为一种可能的实现方式,通过开关电路实现第一驱动芯片及第二驱动芯片与第三数据线组的连接时,可以在通过第二驱动芯片驱动第三显示区域时,控制第二驱动芯片与第三数据线组之间的第二开关电路导通,以及控制第一驱动芯片与第三数据线组之间的第一开关电路断开,从而使得第二驱动芯片可以对第二显示区域与第三显示区域进行驱动,而第一驱动芯片仅可以对第一显示区域进行驱动,以驱动显示屏对当前的显示帧进行完整显示。
本申请实施例提供的显示屏驱动方法,通过在显示屏处于展开状态时,通过两个驱动芯片对整个显示屏进行驱动,且两个驱动芯片驱动的显示区域存在一部分的交叠区域(即第三显示区域),进而使得两个驱动芯片交替驱动第三显示区域进行显示,以使两个驱动芯片所驱动的显示区域的交界处不断交替变换,从而不仅通过两个驱动芯片提升了对显示屏的驱动能力,而且使得两个驱动芯片所驱动的显示区域不存在固定的交界处,使得人眼不易感知交界处的光学差异,提升了显示屏的视觉舒适度。
在本申请一种可能的实现形式中,显示屏未处于展开状态时,可以根据用户当前使用的显示区域,选择其中一个驱动芯片对显示屏进行驱动,以进一步提升显示屏的显示效果,并降低电子设备的功耗。
下面结合图5,对本申请实施例提供的显示屏驱动方法进行进一步说明。
图5为本申请实施例所提供的再一种显示屏驱动方法的流程示意图。
如图5所示,该显示屏驱动方法,包括以下步骤:
步骤301,判断显示屏是否处于展开状态,其中,显示屏为可折叠显示屏,显示屏包括第一显示区域、第二显示区域及第三显示区域,第三显示区域位于第一显示区域与第二显示区域之间,显示屏的折叠线位于第三显示区域内,若是,则执行步骤302;否则,执行步骤305。
步骤302,判断当前的显示帧是否为奇数帧,若是,则执行步骤303;否则,执行步骤304。
步骤303,控制第一驱动芯片与第一显示区域对应的第一数据线组及第三显示区域对应的第三数据线组导通,以及控制第二驱动芯片与第二显示区域的对应的第二数据线组导通,以驱动显示屏对当前的显示帧进行显示。
步骤304,控制第一驱动芯片与第一数据线组导通,以及控制第二驱动芯片与第二数据线组及第三数据线组导通,以驱动显示屏对当前的显示帧进行显示。
上述步骤301-304的具体实现过程及原理,可以参照上述实施例的详细描述,此处不再赘述。
步骤305,控制第一驱动芯片向第一扫描线组发送第一时序信号,以通过第一扫描线组导通显示屏中每个像素点对应的开关的栅极,以及控制第一驱动芯片与第一数据线组及第三数据线组导通,并关闭第二驱动芯片,以驱动显示屏对当前的显示帧进行显示;或者,控制第二驱动芯片向第二扫描线组发送第二时序信号,以通过第二扫描线组导通显示屏中每个像素点对应的开关的栅极,以及控制第二驱动芯片与第二数据线组及第三数据线组导通,并关闭第一驱动芯片,以驱动显示屏对当前的显示帧进行显示。
在本申请实施例中,若确定显示屏未处于展开状态,如处于折叠状态、支撑状态等,则可以根据 用户当前使用的显示区域,确定对显示屏的驱动策略。具体的,若确定用户当前使用的显示区域为第一显示区域所在的显示区域,则可以控制第一驱动芯片向第一扫描线组发送第一时序信号,以使第一驱动芯片驱动显示屏中每个像素点对应的开关的栅极打开;之后,控制第一驱动芯片与第一数据线组及第三数据线组导通,以使第一驱动芯片通过第一数据线组与第三数据线组,向显示屏发送显示数据,即利用第一驱动芯片驱动第一显示区域与第三显示区域,对当前的显示帧进行显示;并且,可以关闭第二驱动芯片(比如断开第二驱动芯片的供电通路),以使第二显示区域处于休眠状态,以节约电子设备的功耗。
相应的,若确定用户当前使用的显示区域为第二显示区域所在的显示区域,则可以控制第二驱动芯片向第二扫描线组发送第二时序信号,以使第二驱动芯片驱动显示屏中每个像素点对应的开关的栅极打开;之后,可以控制第二驱动芯片与第二数据线组及第三数据线组导通,以使第二驱动芯片通过第二数据线组与第三数据线组,向显示屏发送显示数据,即利用第二驱动芯片驱动第二显示区域与第三显示区域,对当前的显示帧进行显示;并且,可以关闭第一驱动芯片(比如断开第一驱动芯片的供电通路),以使第一显示区域处于休眠状态。
需要说明的是,为保证显示屏处于折叠状态、支撑状态等情况时,用户所使用的显示区域可以对显示帧进行完全显示,以不影响用户的正常使用,可以根据电子设备的厚度确定第三显示区域的宽度。比如,第三显示区域的宽度可以为电子设备厚度的两倍,从而在显示屏处于折叠或支撑状态时,当前显示帧的绝大部分区域均由第一显示区域或第二显示区域进行显示,第三显示区域仅用于对显示帧的极小部分进行显示,从而不仅可以保证显示屏对显示帧的正常显示,而且可以实现良好的瀑布屏效果,以进一步提升显示屏的显示效果和视觉舒适度。
作为一种可能的实现方式,在显示屏所在的电子设备中包括摄像头时,可以在显示屏未处于展开状态时,根据电子设备中摄像头采集的图像,确定用户当前使用的显示区域。即在本申请实施例一种可能的实现方式中,上述显示屏所在的电子设备中可以包括摄像头;相应的,上述步骤305,可以包括:

在申请实施例中,若显示屏所在的电子设备中包括摄像头,在确定显示屏未处于展开状态时,可以控制电子设备中的摄像头采集参考图像,以根据参考图像的图像内容及摄像头所在的位置,确定用户当前使用的显示区域,进而根据用户当前使用的显示区域,确定对显示屏的驱动策略。
可选地,若第一显示区域包括摄像头,则可以在摄像头采集的参考图像中包括用户人脸时,确定用户当前注视第一显示区域;相应的,若摄像头采集的参考图像中未包含用户人脸,则可以确定用户当前注视第二显示区域。
可选地,若第二显示区域包括摄像头,则可以在摄像头采集的参考图像中包括用户人脸时,确定用户当前注视第二显示区域;相应的,若摄像头采集的参考图像中未包含用户人脸,则可以确定用户当前注视第一显示区域。

作为另一种可能的实现方式,在显示屏未处于展开状态时,还可以根据用户对显示屏的触摸情况,确定用户当前使用的显示区域。即在本申请实施例一种可能的实现方式中,上述步骤305,可以包括:
获取用户手指与第一显示区域的第一接触面积,及与第二显示区域的第二接触面积;

在第一接触面积大于第二接触面积时,控制第二驱动芯片向第二扫描线组发送第二时序信号,以通过第二扫描线组导通显示屏中每个像素点对应的开关的栅极;
控制第二驱动芯片与第二数据线组及第三数据线组导通,并关闭第一驱动芯片,以驱动显示屏对当前的显示帧进行显示。
在申请实施例中,确定显示屏未处于展开状态时,还可以通过显示屏中的触控单元获取用户手指对显示屏的触摸情况,以根据用户手指对显示屏的触摸情况,确定用户当前使用的显示区域,进而根据用户当前使用的显示区域,确定对显示屏的驱动策略。
可选地,在显示屏未处于展开状态,如电子设备处于折叠状态时,若用户手持电子设备,则用户当前未使用的显示区域与用户手指的接触面积通常较大。因此,可以获取用户手指与第一显示区域的第一接触面积,以及与第二显示区域的第二接触面积。若第一接触面积小于第二接触面积,则可以确定用户当前使用的显示区域为第一显示区域,从而可以控制第一驱动芯片向第一扫描线组发送第一时序信号,以使第一驱动芯片驱动显示屏中每个像素点对应的开关的栅极打开;之后,控制第一驱动芯片与第一数据线组及第三数据线组导通,以使第一驱动芯片通过第一数据线组与第三数据线组,向显示屏发送显示数据,即利用第一驱动芯片驱动第一显示区域与第三显示区域,对当前的显示帧进行显示;并且,可以关闭第二驱动芯片,以使第二显示区域处于休眠状态。
相应的,若第一接触面积大于第二接触面积,则可以确定用户当前使用的显示区域为第二显示区域,从而可以控制第二驱动芯片向第二扫描线组发送第二时序信号,以使第二驱动芯片驱动显示屏中每个像素点对应的开关的栅极打开;之后,可以控制第二驱动芯片与第二数据线组及第三数据线组导通,以使第二驱动芯片通过第二数据线组与第三数据线组,向显示屏发送显示数据,即利用第二驱动芯片驱动第二显示区域与第三显示区域,对当前的显示帧进行显示;并且,可以关闭第一驱动芯片,以使第一显示区域处于休眠状态。
可选地,在显示屏未处于展开状态且用户手持电子设备,则用户当前未使用的显示区域与用户手指的接触点的数量通常较多,从而还可以根据用户手指与显示屏各区域的接触点的数量,确定用户当前使用的显示区域。因此,可以获取用户手指与第一显示区域的第一接触点数量,以及与第二显示区域的第二接触点数量。若第一接触点数量小于第二接触点数量,则可以确定用户当前使用的显示区域为第一显示区域;相应的,若第一接触点数量大于第二接触点数量,则可以确定用户当前使用的显示 区域为第二显示区域。

需要说明的是,确定出用户当前使用的显示区域之后,可以按照上述方式确定对显示屏的驱动策略,具体实现过程及原理,可以参照上述实施例的详细描述,此处不再赘述。
本申请实施例提供的显示屏驱动方法,通过在显示屏处于展开状态时,通过两个驱动芯片交替驱动第三显示区区域,以及在显示屏未处于展开状态时,根据显示屏所在的电子设备中的摄像头采集的参考图像,或用户手指对显示屏的触摸情况,确定用户当前使用的显示区域,进而根据用户当前使用的显示区域,选择一个驱动芯片对显示屏进行驱动。由此,通过使得两个驱动芯片交替驱动第三显示区域进行显示,以使两个驱动芯片所驱动的显示区域的交界处不断交替变换,并且在显示屏未处于展开状态时,选择一个驱动芯片对显示屏进行驱动,从而不仅通过两个驱动芯片提升了对显示屏的驱动能力,使得两个驱动芯片所驱动的显示区域不存在固定的交界处,使得人眼不易感知交界处的光学差异,而且可以实现显示屏处于折叠状态时的瀑布屏效果,进一步提升了显示屏的显示效果和视觉舒适度,并且降低了显示屏处于折叠状态时电子设备的功耗。
