Abstract

一种LED显示屏的配置方法、驱动方法及装置，LED显示屏的配置方法通过对驱动芯片进行第一地址信息和第一启动信息的配置，在对驱动芯片驱动时，通过第一地址信息可以确定待开启的目标驱动芯片，由于每个驱动芯片配置第一启动信息，每个第一启动信息对应一个第一开启时刻，不同驱动芯片对应的第一启动信息不同，不同第一启动信息对应的第一开启时刻不同。由此在同一时刻只有一个驱动芯片开启，又因为每个驱动芯片包括的驱动端口的个数相同，因此在同一时刻，开启的驱动端口的个数相同，处于关闭状态的驱动端口的个数相同，放电的LED灯串的数量相同，驱动端口开启响应速度一致。

LED（Light Emitting Diode，发光二极管）显示屏包括控制器、LED阵列和多个驱动芯片，每个驱动芯片包括多个驱动端口，每个驱动端口用于驱动一列LED灯串。
控制器用于将视讯源输出的显示画面数据转换成灰度数据信号和控制信号，并将灰度数据信号和控制信号传送至驱动芯片中。驱动芯片根据控制信号确定驱动端口的开启时刻或关闭时刻，驱动芯片根据灰度数据信号确定驱动端口的开启时长。

如图1和图2所示，LED显示屏包括控制器、LED阵列和多个驱动芯片，每个驱动芯片包括多个驱动端口，每个驱动端口用于驱动一列LED灯串。
控制器用于将视讯源输出的显示画面数据转换成灰度数据信号和控制信号，并将灰度数据信号和控制信号传送至驱动芯片中。驱动芯片根据控制信号确定驱动端口的开启时刻或关闭时刻，驱动芯片根据灰度数据信号确定驱动端口的开启时长。如图2所示，驱动端口开启方式1：驱动端口根据控制信号在第y+1时刻开启，灰度数据信号控制驱动端口开启m个灰度时钟周期。驱动端口开启方式2：驱动端口根据控制信号在第y+m时刻关闭，灰度数据信号控制驱动端口开启m个灰度时钟周期。
当驱动端口开启时，处于关闭状态的驱动端口对应的列LED灯串会通过开启的驱动端口放电，放电的LED灯串影响驱动端口的开启响应速度。如图1所示，第一个驱动端口开启（ON），另外三个驱动端口处于关闭状态（OFF），处于关闭状态的驱动端口对应的LED灯串向开启的驱动端口放电。同一时刻，驱动端口开启的数量发生变化，处于关闭状态的驱动端口的数量随之变化，放电的LED灯串的数量随之变化。放电LED灯串数量的变化会引起驱动端口开启响应速度发生变化，造成驱动端口开启响应速度不一致，影响显示效果。
基于上述问题，本申请实施例提供了一种LED显示屏的配置方法，如图3所示，LED显示屏包括多个驱动芯片，每个驱动芯片包括的驱动端口的个数相同，LED显示屏的配置方法包括步骤S301和步骤S302。
步骤S301，为每个驱动芯片配置第一地址信息，不同驱动芯片对应的第一地址信息不同。
步骤S302，为每个驱动芯片配置第一启动信息，每个第一启动信息对应一个第一开启时刻，不同驱动芯片对应的第一启动信息不同，不同第一启动信息对应的第一开启时刻不同。
具体地，通过对驱动芯片进行第一地址信息和第一启动信息的配置，在对驱动芯片驱动时，通过第一地址信息可以确定待开启的目标驱动芯片，由于每个驱动芯片配置第一启动信息，每个第一启动信息对应一个第一开启时刻，不同驱动芯片对应的第一启动信息不同，不同第一启动信息对应的第一开启时刻不同。由此在同一时刻只有一个驱动芯片开启，又因为每个驱动芯片包括的驱动端口的个数相同，因此在同一时刻，开启的驱动端口的个数相同，处于关闭状态的驱动端口的个数相同，放电的LED灯串的数量相同，驱动端口开启响应速度一致。
图4示出了本申请一实施例提供的LED显示屏的控制时序图。参见图4所示，LED显示屏包括n×n个驱动芯片，其中每n个芯片为一组，所有的驱动芯片包括的驱动端口的个数相同。
首先，为每个驱动芯片配置第一地址信息，第一组驱动芯片的地址分别为Add_1-1、Add_1-2……Add_1-n，第二组驱动芯片的地址分别为Add_2-1、Add_2-2……Add_2-n，第n组驱动芯片的地址分别为Add_n-1、Add_n-2……Add_n-n。
然后，为每个驱动芯片配置第一启动信息，例如，如图4所示，将地址为Add_1-1的驱动芯片的开启时刻设为第x个灰度时钟信号，将地址为Add_1-2的驱动芯片的开启时刻设为第x+1个灰度时钟信号，将地址为Add_1-n的驱动芯片的开启时刻设为第x+n-1个灰度时钟信号，将地址为Add_n-n的驱动芯片的开启时刻设为第z+n-1个灰度时钟信号。
通过以上配置，在同一时刻，最多只能有一个驱动芯片执行开启动作。又因为每个驱动芯片包括的驱动端口的个数相同，因此在同一时刻，开启的驱动端口的个数相同，处于关闭状态的驱动端口的个数相同，放电的LED灯串的数量相同，驱动端口开启响应速度一致。
本申请的一个实施例中，LED显示屏的配置方法还包括步骤S303和步骤S304。
步骤S303，获取多组对应的第一地址信息、第一启动信息。
步骤S304，将多组对应的第一地址信息和第一启动信息进行存储。
具体的，通过将第一地址信息和第一启动信息进行关联，然后将关联后的第一地址信息和第一启动信息进行存储。在对驱动芯片驱动时，通过在控制信号中获取第一地址信息后，即可以确定待开启的目标驱动芯片。然后通过第一地址信息确定对应的第一启动信息，确定目标驱动芯片的开启时刻。在目标驱动芯片开启时，其它的驱动芯片不能开启，保证在同一时刻，只有一个驱动芯片开启。从而保证在同一时刻开启的驱动端口的数量一致，处于关闭状态的驱动端口的个数相同，放电的LED灯串的数量相同，驱动端口开启响应速度一致。
图5出了本申请另一实施例提供的LED显示屏的配置方法的流程示意图。参见图5示，LED显示屏包含多个驱动芯片，每个驱动芯片包括多个驱动端口，LED显示屏的配置方法包括步骤S501和步骤S502。
步骤S501，为每个驱动端口配置第二地址信息，不同驱动端口对应的第二地址信息不同。
步骤S502，为每个驱动端口配置第二启动信息，每个第二启动信息对应一个第二开启时刻，不同驱动端口对应的第二启动信息不同，不同第二启动信息对应的第二开启时刻不同。
具体的，通过对驱动端口进行第二地址信息和第二启动信息的配置，在对驱动端口驱动时，通过第二地址信息可以确定待开启的目标驱动端口，由于每个驱动端口配置第二启动信息，每个第二启动信息对应一个第二开启时刻，不同驱动端口对应的第二启动信息不同，不同第二启动信息对应的第二开启时刻不同。由此在同一时刻只有一个驱动端口开启，处于关闭状态的驱动端口的个数相同，放电的LED灯串的数量相同，驱动端口开启响应速度一致。
本申请的一个实施例中，LED显示屏的配置方法还包括步骤S503和步骤S504。
步骤S503，获取多组对应的第二地址信息、第二启动信息。
步骤S504，将多组对应的第二地址信息和第二启动信息进行存储。
具体的，通过将第二地址信息和第二启动信息进行关联，然后将关联后的第二地址信息和第二启动信息进行存储。在对驱动端口驱动时，通过在控制信号中获取第二地址信息后，即可以确定待开启的目标驱动端口。然后通过第二地址信息确定对应的第二启动信息，确定目标驱动端口的开启时刻。在目标驱动端口开启时，其它的驱动端口不能开启，保证在同一时刻，只有一个驱动端口开启，处于关闭状态的驱动端口的数量不变，放电的LED灯串的数量不变，驱动端口开启响应速度一致。
图6示出了本申请一实施例提供的LED显示屏的驱动方法的流程示意图。参见图6所示，LED显示屏的驱动方法包括步骤S601至步骤S604。
步骤S601，获取第一控制信号信息和第一灰度数据信息。
具体地，LED显示屏中的控制器将视讯源输出的显示画面数据转换成第一灰度数据信号和第一控制信号信息，并将第一灰度数据信号和第一控制信号信息传送至驱动芯片中。以此实现驱动芯片对第一灰度数据信号和第一控制信号信息的获取。
步骤S602，对第一控制信号信息进行解析，得到第一目标地址信息。
具体地，第一控制信号信息中包含第一目标地址信息，通过对第一控制信号信息的解析，可以得到第一目标地址信息。
步骤S603，根据第一目标地址信息确定驱动芯片的第一目标开启时刻。
具体地，每个驱动芯片均配置一个第一地址信息和第一目标开启信息，根据第一目标地址信息后可以确定第一目标开启信息，然后根据第一目标开启信息确定第一目标开启时刻。在目标驱动芯片在第一目标开启时刻开启时，其它的驱动芯片均处于关闭状态。
步骤S604，根据第一灰度数据信息确定驱动芯片的第一开启时长。
具体地，当驱动芯片的开启时刻确定后，再根据第一灰度数据信息确定驱动芯片的第一开启时长，以此完成驱动芯片的驱动。
示例性的，LED显示屏包括n个驱动芯片，每个驱动芯片包括m个驱动端口。在控制信号的驱动下，同一时刻只有一个驱动芯片开启，有m个驱动端口同时开启。驱动端口的开启数量始终保持一致，处于关闭状态的驱动端口的数量保持一致，放电的LED灯串的数量也保持一致，从而使驱动端口开启响应速度保持一致，有利于提高显示效果。
图7示出了本申请另一实施例提供的LED显示屏的驱动方法的流程示意图。参见图7所示，LED显示屏的驱动方法包括步骤S701至步骤S704。
步骤S701，获取第二控制信号信息和第二灰度数据信息。
具体地，LED显示屏中的控制器将视讯源输出的显示画面数据转换成第二灰度数据信号和第二控制信号信息，并将第二灰度数据信号和第二控制信号信息传送至驱动芯片中。以此实现驱动芯片对第二灰度数据信号和第二控制信号信息的获取。
步骤S702，对第二控制信号信息进行解析，得到第二目标地址信息。
具体地，第二控制信号信息中包含第二目标地址信息，通过对第二控制信号信息的解析，可以得到第二目标地址信息。
步骤S703，根据第二目标地址信息确定驱动端口的第二目标开启时刻。
具体地，每个驱动端口均配置一个第二地址信息和第二目标开启信息，根据第二目标地址信息后可以确定第二目标开启信息，然后根据第二目标开启信息确定第二目标开启时刻。在目标驱动端口在第二目标开启时刻开启时，其它的驱动端口均处于关闭状态。
步骤S704，根据第二灰度数据信息确定驱动端口的第二开启时长。
具体地，当驱动端口的开启时刻确定后，再根据第二灰度数据信息确定驱动芯端口的第二开启时长，以此完成驱动端口的驱动。
示例性的，LED显示屏包括n个驱动芯片，每个驱动芯片包括m个驱动端口。在控制信号的驱动下，同一时刻只有一个驱动端口开启。驱动端口的开启数量始终保持一致，处于关闭状态的驱动端口的数量保持一致，放电的LED灯串的数量也保持一致，从而使驱动端口开启响应速度保持一致，有利于提高显示效果。
