本公开的一些实施例提供一种显示组件10,如图1所示,包括:K个时序控制器11、K个数据驱动电路和显示面板。
K个时序控制器11中的每个时序控制器11被配置为接收由一帧图像数据中第i行像素数据分成的K组像素数据(Data)中的一组像素数据,且不同时序控制器接收不同组像素数据。K为大于等于2的正整数,i∈{1,2,3,···,n},n为大于等于1的正整数。
示例的,一帧图像数据中第i行像素数据分成了K组像素数据,第1个时序控制器11接收第一组像素数据,第2个时序控制器11接收第二组像素数据,依次类推,第K个时序控制器11接收第K组像素数据。这里,第i行像素数据为一帧图像数据中的任意一行像素数据。
示例的,K组像素数据中的每组像素数据均包括相同个数的像素数据。相应的,每个时序控制器11接收对应的一组像素数据的时长相同。
若K组像素数据中的每组像素数据包括的像素数据的个数不同,则包括较多像素数据的组别对应的时序控制器11接收一组像素数据的时长较长,而包括较少像素数据的组别对应的时序控制器11接收一组像素数据的时长较短。这样,在接收下一行像素数据之前,即在接收第i+1行像素数据之前,会 出现等待间隙,导致出现像素数据丢失的问题。因此,每组像素数据中像素数据的个数相同,可避免由于接收时长不同而导致的像素数据丢失问题。
如图1所示,K个数据驱动电路12中的一个数据驱动电路12与K个时序控制器11中对应的一个时序控制器11连接,每个数据驱动电路12被配置为接收来自对应的时序控制器11的一组像素数据,并根据该组像素数据,输出一组数据电压。
示例的,第1个数据驱动电路12与第1个时序控制器11连接,第1个数据驱动电路12接收来自第1个时序控制器11的第1组像素数据,并根据该组像素数据,输出第1组数据电压。第2个数据驱动电路12与第2个时序控制器11连接,第2个数据驱动电路12接收来自第2个时序控制器11的第2组像素数据,并根据该组像素数据,输出第2组数据电压。依次类推,第K个数据驱动电路12与第K个时序控制器11连接,第K个数据驱动电路12接收来自第K个时序控制器11的第K组像素数据,并根据该组像素数据,输出第K组数据电压。
示例的,除了接收对应的一组像素数据,每个时序控制器11还接收垂直同步信号VS、水平同步信号HS和数据使能信号DE。时序控制器11根据垂直同步信号VS、水平同步信号HS和数据使能信号DE控制对应的数据驱动电路12,以使数据驱动电路12根据来自对应的时序控制器11的一组像素数据,输出一组数据电压。
如图1所示,显示面板14与K个数据驱动电路电连接。该显示面板14被配置为接收K个数据驱动电路12输出的K组数据电压并进行显示。这里,显示面板14包括多行像素,在显示面板14显示一帧图像数据的情况下,显示面板14的第i行像素显示上述的一帧图像数据中的第i行像素数据。
本公开实施例提供的显示组件10包括K个时序控制器11,K个数据驱动电路12和显示面板14。通过多个时序控制器11分别接收由一帧图像数据中第i行像素数据分成的K组像素数据中的一组像素数据,从而可以在传输技术中带宽受限的情况下,传输高带宽的像素数据。
在一些实施例中,如图2A-图2C所示,显示组件10还包括栅极驱动电路13。栅极驱动电路13与K个时序控制器中的一个时序控制器11和显示面板14电连接。时序控制器11还被配置为向该栅极驱动电路13传输控制信号,该栅极驱动电路13被配置为根据接收的来自与该栅极驱动电路13连接的时序控制器11的控制信号,向显示面板14输出栅极扫描信号,以使在显示面 板14中的与第i行像素连接的栅线接收到该栅极扫描信号时,显示面板14的第i行像素接收来自K个数据驱动电路的K组数据电压并进行显示。
这里,来自与该栅极驱动电路13连接的时序控制器11的控制信号为:与该栅极驱动电路13连接的时序控制器11根据K个时序控制器11中的除该时序控制器11以外的其他K-1个时序控制器11的状态所输出。
在一些示例中,如图2A所示,显示组件10包括两个时序控制器11(分别记为TCON1和TCON2)、两个数据驱动电路12(分别记为DDRV1和DDRV2)。TCON1与DDRV1相连接,TCON2与DDRV2相连接;栅极驱动电路13与TCON1相连接。TCON1根据TCON2的状态输出控制信号,控制栅极驱动电路13,即栅极驱动电路13根据该控制信号,向显示面板14输出栅极扫描信号。
当然,栅极驱动电路13也可以与TCON2相连接。基于此,与上述栅极驱动电路13与TCON1相连接类似,TCON2根据TCON1的状态输出控制信号,控制栅极驱动电路13。

S11、TCON2将接收的第2组像素数据全部输出至DDRV2后,TCON2通过L
21向TCON1发送高电平信号;
S12、TCON1响应于接收到的来自TCON2的高电平信号,以及确定已经将第1组像素数据全部输出至DDRV1,输出控制信号至SDRV,以使SDRV响应于接收到该控制信号,向显示面板14输出栅极扫描信号;以使在显示面板14中的与第i行像素连接的栅线接收到该栅极扫描信号时,第i行像素接收来自DDRV1的第1组数据电压和来自DDRV2的第2组数据电压;也就是说,第i行像素数据已经被传输至显示面板14。
S13、在输出控制信号至SDRV的同时,TCON1通过L
12向TCON2发送持续一段时长的高电平信号,再发送低电平信号,以告知TCON2第i行像素数据已经送出。
S14、TCON2响应于接收到的来自TCON1的高电平信号时,通过L
21向TCON1发送低电平信号。在TCON2向DDRV2输出由第i+1行像素数据分成的第2组像素数据后,再通过L
21向TCON1发送高电平信号,依次类推。
示例的,S13中,TCON1通过L
12向TCON2发送持续一段时长的高电平信号,这里,高电平信号持续的时长为TCON1向DDRV1传输由第i行像素数据分成的第1组像素数据的时长的一半。这样,可以防止高电平信号持续时长太短,TCON2侦测不到。需要说明的是,在栅极驱动电路13与TCON2连接的情况下,TCON2根据TCON1的状态输出控制信号控制栅极驱动电路13的过程与上述S11-S14类似,在此不再赘述。
在另一些示例中,如图2B所示,显示组件10包括三个时序控制器11(分别记为TCON1、TCON2和TCON3)、三个数据驱动电路(分别记为DDRV1、DDRV2和DDRV3)。TCON1与DDRV1相连接,TCON2与DDRV2相连接,TCON3与DDRV3相连接;栅极驱动电路13与TCON1相连接。TCON1根据TCON2和TCON3的状态输出控制信号,控制栅极驱动电路13,即栅极驱动电路13根据该控制信号,向显示面板14输出栅极扫描信号。
当然,栅极驱动电路13也可以与TCON2或TCON3相连接,本公开实施例对此不进行限制。例如,栅极驱动电路13与TCON3相连接,基于此,与上述栅极驱动电路13与TCON1相连接类似,TCON3根据TCON1和TCON2的状态输出控制信号,控制栅极驱动电路13。又例如,栅极驱动电路13与TCON2相连接,基于此,与上述栅极驱动电路13与TCON1相连接类似,TCON2根据TCON1和TCON3的状态输出控制信号,控制栅极驱动电路13。
示例的,TCON1包括两个端口,TCON2包括4个端口,TCON3包括两个端口。TCON1和TCON2的端口两两相连接,形成两条连接线路L
12和L
21,L
12被配置为向TCON2传输表明TCON1状态的信号,L
21被配置为向TCON1传输表明TCON2状态的信号。TCON2和TCON3的端口两两相连接,形成两条连接线路L
23和L
32,L
23被配置为向TCON3传输表明TCON2状态的信号,L
32被配置为向TCON2传输表明TCON3状态的信号。这里,各端口例如为各时序控制器11的引脚。
以下以将第i行像素数据分成3组像素数据,TCON1接收第1组像素数据,TCON2接收第2组像素数据,TCON3接收第3组像素数据;且栅极驱动电路13与TCON1连接为例,提供S21-S26,以清楚说明TCON1根据TCON2和TCON3的状态控制SDRV的过程。
S21、TCON3将接收的第3组像素数据全部输出至DDRV3后,TCON3通过L
32向TCON2发送高电平信号。
S22、TCON2将接收的第2组像素数据全部输出至DDRV2后,并响应于接收到的来自TCON3的高电平信号,通过L
21向TCON1发送高电平信号。
S23、TCON1响应于接收到的来自TCON2的高电平信号,以及确定已经将第1组像素数据全部输出至DDRV1,输出控制信号至SDRV,以使SDRV响应于接收到该控制信号,向显示面板14输出栅极扫描信号;以使在显示面板14中的与第i行像素连接的栅线接收到该栅极扫描信号时,第i行像素接收来自DDRV1的第1组数据电压、来自DDRV2的第2组数据电压和来自DDRV3的第3组数据电压;也就是说,第i行像素数据已经被传输至显示面板14。
S24、在输出控制信号至SDRV的同时,TCON1通过L
12向TCON2发送持续一段时长的高电平信号,再发送低电平信号,以告知TCON2第i行像素数据已经送出。
S25、TCON2响应于接收的来自TCON1的高电平信号,通过L
23向TCON3发送持续一段时长的高电平信号,再发送低电平信号,以告知TCON3第i行像素数据已经送出;同时,通过L

S26、TCON3响应于接收到的来自TCON2的高电平信号,通过L
32向TCON2发送低电平信号。TCON3向DDRV3输出由第i+1行像素数据分成的第3组像素数据后,再通过L
32向TCON2发送高电平信号,依次类推。
示例的,S23中的TCON1通过L
12向TCON2发送持续一段时长的高电平信号,这里,高电平信号持续的时长为TCON1向DDRV1传输由第i行像素数据分成的第1组像素数据的时长的一半。S25中的TCON2通过L
23向TCON3发送持续一段时长的高电平信号,这里,高电平信号持续的时长为TCON2向DDRV2传输由第i行像素数据分成的第2组像素数据的时长的一半;这样,可以防止高电平信号持续时长太短,TCON2和TCON3侦测不到。
需要说明的是,在栅极驱动电路13与TCON3连接的情况下,TCON3根据TCON1和TCON2的状态输出控制信号控制栅极驱动电路13的过程与上述S21-S26类似,在此不再赘述。
在又一些示例中,如图2C所示,显示组件10包括K个时序控制器11(分别记为TCON1、TCON2、…、TCONK)和K个数据驱动电路(分别记为DDRV1、DDRV2、…、DDRVK)。TCON1与DDRV1相连接,TCON2与DDRV2相连接,TCONK与DDRVK相连接;栅极驱动电路13与TCON1相连接。TCON1根据TCON2至TCONK的状态输出控制信号,控制栅极驱动电路13,即栅极驱动电路13根据该控制信号,向显示面板14输出栅极扫描信号。
在一些实施例中,如图3所示,每个时序控制器11包括第一eDp(Embedded Display Port)接口102。每个第一eDp接口102被配置为接收由一帧图像数据中第i行像素数据分成的K组像素数据中的一组像素数据。示例的,第1个时序控制器11的第一eDp接口102接收由一帧图像数据中第i行像素数据分成的K组像素数据中的第1组像素数据,第2个时序控制器11的第一eDp接口102接收由一帧图像数据中第i行像素数据分成的K组像素数据中的第2组像素数据。
示例的,第一eDP接口102包括4条信道(Lane),每条Lane中的传输速率为1.62Gbps、2.7Gbps和5.4Gbps中的一个,Lane中的传输速率是通过时钟信号来控制的,例如,当时钟信号的频率为A时,相应的一条Lane中的传输速率为1.62Gbps。
通常,在传输过程中,可以根据实际需求来选择1条信道、2条信道或者4条信道(采用多条信道进行传输时,每条信道中的传输速率相同)来进行数据传输,以支持相应的分辨率。例如,本公开实施例中的每个时序控制器11的第一eDP接口102均选择4条信道,并且,每条信道的传输速率为5.4Gbps,以满足传输一帧图像数据的带宽的需要。
在一些示例中,如图4所示,每个时序控制器11还包括第一缓存器(如图4中B1所示)。每个第一缓存器101被配置为存储对应的时序控制器11所接收的一组像素数据。即,每个第一缓存器101被配置为存储对应的时序控制器11的第一eDp接口102所接收的一组像素数据。
示例的,第1个时序控制器11的第一缓存器被配置存储为第1个时序控制器11的第一eDp接口102所接收的由一帧图像数据中第i行像素数据分成的K组像素数据中的第1组像素数据,第2个时序控制器11的第一缓存器被 配置存储为第2个时序控制器11的第一eDp接口102所接收的由一帧图像数据中第i行像素数据分成的K组像素数据中的第2组像素数据。
在一些示例中,如图1-图4所示,显示面板14包括显示区,显示区沿显示面板14中像素的行方向划分成K个子区104,每个子区104中的所有像素与K个数据驱动电路中的一个数据驱动电路12电连接。
示例的,K个数据驱动电路12连接K组数据线15,每组数据线15对应连接K个子区104中的一个子区104的多列像素;1个数据驱动电路12将一组数据电压通过其连接的一组数据线15传输至显示面板14的第i行像素中对应的多列像素中,以使该多列像素显示与该组数据电压对应的一组像素数据,这样,K组像素数据在第i行像素的不同位置处一一显示。
基于此,每个时序控制器11还包括存储器,存储器被配置为存储与该时序控制器11相对应的一个子区104中的第i行像素的数量。
示例的,K个子区104中每个子区104中的第i行像素的数量相等。
又示例的,K个子区104中每个子区104中的第i行像素的数量不完全相等。这里,不完全相等可以被理解为:部分子区104中的第i行像素的数量相等,部分子区104中的第i行像素的数量不相等。例如,第1个子区104至第K-1个子区104中的第i行像素的数量相等,第K个子区104中的第i行像素的数量与第1个子区104中的第i行像素的数量不相等。
在一些示例中,每个时序控制器中的存储器还被配置为存储该时序控制器的显示配置数据(Display Port Configuration Data,DPCD),显示配置数据包括第一eDp接口的信道的数量以及每个信道的传输速率。
本公开一些实施例提供一种显示装置2,如图5所示,该显示装置2包括:主控芯片20和如上述任一实施例的显示组件10。
主控芯片20包括处理器。处理器被配置为接收上述的一帧图像数据,将一帧图像数据中的第i行像素数据分成K组像素数据,并将K组像素数据同时传输至显示组件10中的K个时序控制器。
示例的,处理器接收一帧图像数据是先接收第1行像素数据,接着接收第2行像素数据,以此类推,直至接收完该帧图像数据中的最后一行像素数据。在接收一帧图像数据中的第i行像素数据时,处理器先接收该行像素数据中的第1个像素数据,接着接收该行像素数据中的第2个像素数,以此类推,直至接收完该行像素数据中的最后一个像素数据。因此,处理器是在接收第i行像素数据的同时,将第i行像素数据分成K组像素数据。例如,将接收到 的第1个像素数据至第S个像素数据划分为第1组像素数据,将接收到的第S+1个像素数据至第2S个像素数据划分为第2组像素数据。也就是说,处理器在接收完第i行像素数据的同时,即完成了将第i行像素数据分成K组像素数据的过程,然后,将K组像素数据同时输出至显示组件10中对应的时序控制器11。
本公开实施例提供的显示装置2将第i行像素数据分成K组像素数据,并向显示组件10同时发送该K组像素数据,从而可以在传输技术中带宽受限的情况下,传输较高带宽的像素数据。
在一些实施例中,如图6所示,主控芯片20包括K个第二缓存器201(如图6中B2所示)。假设所述第i行像素数据包括M个像素数据。
处理器还被配置为:将第i行像素数据中由第1个像素数据至第M个像素数据的每S个像素数据依次分别存入第1个第二缓存器201至第K-1个第二缓存器201中;(K-1)×S<M≤K×S;S和M均为正整数。也就是说,第1个第二缓存器至所述第K-1个第二缓存器中每个缓存器中的S个像素数据构成一组像素数据,即,第1个第二缓存器中的S个像素数据为上述的由第i行像素数据分成的第1组像素数据,第2个第二缓存器中的S个像素数据为上述的由第i行像素数据分成的第2组像素数据,依此类推,第K-1个第二缓存器中的S个像素数据为上述的由第i行像素数据分成的第K-1组像素数据。
处理器还被配置为:将第i行像素数据中的第M-(K-1)×S个像素数据至第M个像素数据存入第K个第二缓存器201中。
在一些示例中,处理器还被配置为:生成S-[M-(K-1)×S]个虚拟像素数据,并将S-[M-(K-1)×S]个虚拟像素数据存入第K个第二缓存器201中。也就是说,第K个第二缓存器中的第M-(K-1)×S个像素数据至第M个像素数据以及S-[M-(K-1)×S]个虚拟像素数据构成一组像素数据,即为上述的由第i行像素数据分成的第K组像素数据。
示例的,处理器根据将第i行像素数据分成K组像素数据的情况,生成上述S-[M-(K-1)×S]个虚拟像素数据。这里,存入第K个第二缓存器201中的S-[M-(K-1)×S]个虚拟像素数据并不用于显示。
例如,如图7所示,显示面板14的分辨率为3440×1440,显示面板14的显示区分为两个子区。基于此,显示组件10中包括两个时序控制器11,若两个时序控制器11所控制的显示面板的子区(如图7中所示的L区域和R区域)的宽度均为1720,即,每个子区中第i行像素的数量为1720。此时,处理 器将第i行像素数据平均分割后存储于对应的第二缓存器201即可,即,将第i行像素数据中的第1个像素数据至第1720个像素数据存入第1个第二缓存器201中,将第1721个像素数据至第3440个像素数据存入第2个第二缓存器201中。
又例如,显示面板14的显示区分为两个子区,两个时序控制器11所控制的显示面板的子区的宽度均为1728,但不等于显示面板14的带宽的一半。此时,处理器将第i行像素数据分割为两组像素数据,第1组像素数据包括1728个像素数据,第2组像素数据包括1712个像素数据。这种情况下,在处理器将两组像素数据传输至时序控制器11的过程中,两组像素数据的传输时长不相同,会出现像素数据丢失的问题。因此,处理器生成16个虚拟像素数据,并将该16个虚拟像素数据存入第2个第二缓存器201中第2组像素数据的末尾,使两组像素数据所包括的像素数据的个数相同,传输时长相等,避免了传输过程中像素数据丢失的问题。
在一些示例中,如图8所示,主控芯片20还包括K个第二eDp接口202。K个第二eDp接口202中的一个第二eDp接口202与K个时序控制器11中的一个时序控制器11的第一eDp接口102相连接。示例的,主控芯片20中的第1个第二eDp接口202与显示组件10中第1个时序控制器11的第一eDp接口102相连接。又示例的,主控芯片20中的第2个第二eDp接口202与显示组件10中第2个时序控制器11的第一eDp接口102相连接。
处理器还被配置为:将由第i行像素数据分成的K组像素数据中的一组像素数据通过K个第二eDp接口202中的一个第二eDp接口输出至对应的时序控制器11。
在一些实施例中,处理器还被配置为通过辅助通道(Auxiliary,AUX)读取每个时序控制器11中存储的与该时序控制器11相对应的一个子区104中的第i行像素的数量,以使处理器根据该第i行像素的数量,将与第i行像素对应的第i行像素数据分成K组像素数据。
此外,处理器还被配置为通过AUX读取显示面板14的扩展显示识别数据(Extended Display Identification Data,EDID),EDID包括各显示组件10的性能的基本参数,例如制造商识别码、产品识别码、制造时间、最大显示尺寸、色彩设置、频率限制和支持的分辨率等信息。通过获取扩展显示识别数据以获取显示面板14的显示能力,以使主控芯片20将与该扩展显示识别数据匹配的数据输出至显示组件10,以使其得以正常显示。
需要说明的是,若主控芯片20与显示组件10中的时序控制器11已经提前约定好每个时序控制器11对应的显示面板14的子区104中第i行像素的数量以及与每个子区104的对应关系,则处理器可以不读取每个时序控制器11中存储的与该时序控制器11相对应的一个子区104中的第i行像素的数量,主控芯片20可以直接按照约定信息,将第i行像素数据对应分割后传输至显示组件10中对应的时序控制器11。这样,可以加快显示面板显示第i行像素数据的显示速度。
在一些示例中,处理器还被配置为通过AUX读取每个时序控制器的DPCD,并根据所读取的DPCD获取该时序控制器11的第一eDp接口102的状态。
这里,获取时序控制器11的第一eDp接口102的状态指确认第一eDp接口102的传输参数,如信道的数目,每个信道的传输速率、电压摆幅、预加重、均衡,以及时钟恢复等。
基于此,处理器由读取到的信道数目乘以每个信道的传输速率,计算得到时序控制器11当前所支持的总带宽;通常的,每个信道的传输速率相等。
需要说明的是,处理器可以多次通过AUX读取DPCD,以起到防呆的作用。
在一些示例中,处理器还被配置为接收来自显示组件10中的K个时序控制器11中的每个时序控制器11的热插拔检测信号(Hot-Plug Detect,HPD),以确认每个时序控制器11与主控芯片20是否连接。
示例的,处理器接收来自每个时序控制器11的热插拔检测信号,为:处理器通过第二eDp接口202接收来自每个时序控制器11的第一eDp接口102的热插拔检测信号。
其中,对于来自一个时序控制器11的热插拔检测信号,若处理器响应于接收到的该热插拔检测信号一直为低电平信号,则确认对应的时序控制器11与主控芯片20未连接,此时,主控芯片20与该时序控制器11的握手过程将不进行。若处理器响应于接收到的该热插拔检测信号为高电平信号,并且在接收到该高电平信号之前,接收到的低电平信号持续了100ms及以上,则确认对应的时序控制器11与主控芯片20相连接,可以进行上述第i行像素数据的传输。
示例的,在处理器接收到的热插拔检测信号为高电平信号期间,出现了持续2ms以内的低电平信号的情况,将该情况作为处理器通过辅助通道读取 显示配置数据的触发条件。即,当处理器响应于接收到的来自时序控制器11的热插拔检测信号为高电平信号,接着接收到的来自时序控制器11的热插拔检测信号为持续2ms以内的低电平信号,然后接收到的来自时序控制器11的热插拔检测信号又为高电平信号,则重新读取一次显示配置数据。
基于此,处理器根据K个第二eDp接口202与每个时序控制器11相对应的第一eDp接口102的握手过程(Training)的结果,将第i行像素数据通过第二eDp接口202传输至对应的时序控制器11的第一eDp接口102。
这里,握手过程包括上述的处理器通过辅助通道读取扩展显示识别数据、通过辅助通道读取显示配置数据、以及接收热插拔检测信号。
