具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公 开实施例的附图,对本公开实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不是全部的实施例。基于所描述的本公开的实施例,本领域普通技术人员在无需创造性劳动的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。
除非另外定义,本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性,而只是用来区分不同的组成部分。同样,“一个”、“一”或者“该”等类似词语也不表示数量限制,而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同,而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接,而是可以包括电性的连接,不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系,当被描述对象的绝对位置改变后,则该相对位置关系也可能相应地改变。
如图1所示,当一显示面板4在显示时,信号源1输入的像素数据信号通过现场可编程门阵列2(FPGA,Field Programmable Gate Array)转换为晶体管-晶体管逻辑电平信号(TTL),然后挂载在现场可编程门阵列2外的解析芯片3将TTL信号转换为低压差分信号(LVDS,Low Voltage Differential Signaling),该低压差分信号再被传送至显示面板4以实现显示。
由于上述显示方法需要在现场可编程门阵列外挂载一颗解析芯片,成本可能较高。
为了避免在FPGA外挂载解析芯片,可以利用FPGA直接调用其内部的LVDS IP核资源,将输入FPGA的像素数据通过此LVDS IP核直接转换为LVDS信号后再发送至显示面板进行显示。但是显示面板在显示时会出现画面异常的问题。例如,如图2A所示,肉眼观察红色和蓝色之间会出现一条黑色的条纹,而用显微镜观察该黑色条纹时发现它其实有颜色,且为红色,但是其亮度很低。另外如图2B所示,黑白颜色转变时在黑色像素和白色像素之间有一列像素仅显示红色,但此红色比右侧白色像素中的红色子像素的亮度要暗一些;而白黑颜色转变时在白色像素和黑色像素之间的一列像素虽然为红绿蓝(R/G/B)三色,但其中红色子像素的亮度很低。由此可知,若直接调用FPGA内部的LVDS IP核资源,将像素数据转换为LVDS信号进行 显示时,画面中颜色不同的两个区域的临近切换点的像素会出现显示异常的现象。
本申请人对上述异常现象进行了进一步的研究,在试验中向FPGA输入特定的画面对应的像素数据,例如,该特定的画面为白黑黑白黑黑(例如,只点亮RGB子像素的最高位数据:R7、B7、G7),但是在显示面板显示时用显微镜观察该显示面板时出现了画面异常现象。即如果是正常显示,在显微镜下观察到的显示面板中的各个子像素的排列应该如表1所示:
表1
B G R B G R B G R B G R
1 1 1 0 0 0 0 0 0 1 1 1
但是实际用显微镜进行观察时,出现了表2的排列顺序:
表2
B G R B G R B G R B G R
1 1 0 0 0 1 0 0 0 1 1 0
通过表1和表2的对比,发现红色子像素(R)的R7数据发生了位移,并通过多次试验进行验证,显示异常的现象是由像素数据发生位移导致的。继而研究发现像素数据发生位移是由于从LVDS IP核输出的LVDS信号标准与显示面板上的视频电子标准协会(Video Electronics Standards Association,VESA)标准中的数据映射(data mapping)不一致。
本公开的实施例提供了一种数据转换方法、显示方法、数据转换装置及显示装置。通过使从FPGA中的LVDS IP核输出的LVDS信号标准与后端显示面板上的VESA信号标准中的data mapping一致,从而不需要在现场可编程门阵列外挂载解析芯片也能正常显示,进而可以降低成本。
附图中各部件的形状和大小不反映真实比例,目的只是示意说明本公开的内容。
本公开的实施例提供一种数据转换方法,例如,该数据转换方法可以应用于显示面板进行显示,该数据转换方法包括:对显示面板中的至少一行像素对应的原始像素数据进行数据重组以获得重组像素数据。需要说明的是,在本公开的实施例中,将进行数据重组前的数据称为原始像素数据,将原始 像素数据进行数据重组后获得的数据称为重组像素数据,以下各实施例与此相同,不再赘述。
原始像素数据通过至少一个数据通道按照第一时钟周期进行传输,任一一个数据通道传输的原始像素数据按照第一时钟周期划分为N个原始像素数据组,每个原始像素数据组包括顺序排列的第一原始部分和第二原始部分。
重组像素数据通过至少一个数据通道按照不同于第一时钟周期的第二时钟周期进行传输,任一一个数据通道传输的重组像素数据按照第一时钟周期划分为多个重组像素数据组,每个重组像素数据组包括顺序排列的第一重组部分和第二重组部分。

例如,如图3所示,在一个示例中,原始像素数据可以通过四个数据通道(OLV0、OLV1、OLV2和OLV3)按照第一时钟周期进行传输,例如第一时钟周期为对应于LVDS信号标准的循环周期。也就是说,在任一一个数据通道中,LVDS信号标准将位于同一个第一时钟周期内的数据认为是对应于同一个像素的数据。
相应地,重组像素数据也可以通过上述四个数据通道进行传输,但重组像素数据是按照第二时钟周期进行传输,例如,在一个示例中,第二时钟周期对应于显示面板VESA标准的循环周期,例如,当显示面板采用HX8861芯片时,则第二时钟周期对应于HX8861信号标准的循环周期。也就是说,在任一一个数据通道中,HX8861信号标准将位于同一个第二时钟周期内的数据认为是对应于同一个像素的数据。
如图3所示,如果不对原始像素数据进行处理,则原始像素数据按照第一时钟周期(例如LVDS信号标准)被传输至显示面板,显示面板在显示时是按照第二时钟周期(例如VESA信号标准)对原始像素数据进行显示的,此时,由于前后两个信号标准的不同会导致该显示面板在显示原始像素数据 时发生显示异常。
例如,在任一一个数据通道中,第一原始部分的位数为第二时钟周期相对于第一时钟周期错开的数据位数。如图3所示,在该示例中,第一时钟周期和第二时钟周期错开两个数据位,也就是说,第一原始部分的位数为2。同时,在本公开的实施例中,将第二时钟周期相对于第一时钟周期错开的数据位数定义为“位移位数x”,也就是说,对于图3所示的示例,位移位数x=2。本公开的实施例包括但不限于此,位移位数可以根据实际采用的信号标准进行确定,例如,位移位数x可以预先获取。
在本公开的一些实施例中,例如,每个像素包括三个子像素(红色子像素R、绿色子像素G和蓝色子像素B),每个子像素对应的原始像素数据包括8位数据,每个像素对应的原始像素数据除了包括上述三个子像素对应的24位数据外,还包括三位控制位(DE、VS和HS)以及一个空位(如图中通道OLV3中的“-”所示)。每个像素对应的28位原始像素数据通过四个数据通道进行传输,每一个数据通道传输7位原始像素数据,即每一个原始像素数据组包括7位数据。
相应地,经过数据重组获得的重组像素数据也通过该四个数据通道进行传输,每一个数据通道传输7位重组像素数据,即每一个重组像素数据组包括7位数据。另外,在图3所示的示例中,每一个原始像素数据组中的第一原始部分包括两位数据,第二原始部分包括五位数据;相应地,每一个重组像素数据组中的第一重组部分包括两位数据,第二重组部分包括五位数据。本公开的实施例包括但不限于此,根据不同的信号标准和不同的位移位数x,原始像素数据组(重组像素数据组)包括的数据位数、第一原始部分(第一重组部分)的位数以及第二原始部分(第二重组部分)的位数可以不同。
需要说明的是,在本公开的实施例中,第一重组部分包括的数据位数和第一原始部分包括的数据位数相等,第二重组部分包括的数据位数和第二原始部分包括的数据位数相等;以下各实施例与此相同,不再赘述。
本公开的实施例提供的数据转换方法,对显示面板中的至少一行像素对应的原始像素数据进行数据重组以获得重组像素数据,从而使得在任一一个数据通道中,第n个重组像素数据组中的第一重组部分由第n-1个原始像素数据组中的第一原始部分组成,第n个重组像素数据组中的第二重组部分由第n个原始像素数据组中的第二原始部分组成。从而使得获得的重组像素数 据转换为LVDS信号后可以与显示面板中的VESA信号标准中的data mapping保持一致,从而不需要在现场可编程门阵列外挂载解析芯片也能正常显示,进而可以降低成本。
需要说明的是,本公开的实施例提供的数据转换方法对实施对象不作限定,例如可以用于显示面板中的一行像素对应的原始像素数据,也可以用于显示面板中的多行像素对应的原始像素数据。
如图3所示,在本公开的实施例中是以四个数据通道为例进行说明的,本公开的实施例包括但不限于此,在对原始像素数据进行传输时可以根据需要以及应用场景对数据通道的个数进行设置,例如,原始像素数据还可以通过一个、两个、三个、五个或更多个数据通道进行传输。
例如,在本公开的实施例提供的数据转换方法中,在对显示面板中的至少一行像素对应的原始像素数据进行数据重组以获得重组像素数据之后,数据转换方法还包括:将重组像素数据转换为低压差分信号(LVDS信号)以用于显示面板进行显示。
例如,在本公开的实施例提供的数据转换方法中,在任一一个数据通道中,N个原始像素数据组重组完后获得N+1个重组像素数据组;对显示面板中的至少一行像素对应的原始像素数据进行数据重组以获得重组像素数据还包括:第一个重组像素数据组的第一重组部分由任意数据组成,第一个重组像素数据组的第二重组部分由第一个原始像素数据组的第二原始部分组成;第N+1个重组像素数据组的第一重组部分由第N个原始像素数据组中的第一原始部分组成,第N+1个重组像素数据组中的第二重组部分由任意数据组成。
例如,在采用二进制数据的情形下,原始像素数据(或重组像素数据)中每一位数据可以是0或1,因此在本公开的实施例中,任意数据可以是0,也可以是1,本公开的实施例对任意数据的具体取值不作限定。
例如,在本公开的一个实施例提供的数据转换方法中,以位移位数x=2为例,重组前的原始像素数据和重组后获得的重组像素数据如表3所示:
表3
Figure PCTCN2018121104-appb-000001
Figure PCTCN2018121104-appb-000002
表3中用7位数据来示例一个原始像素数据组(或重组像素数据组),例如,此处的7位数据为对应一个数据通道在一个时钟周期中的数据。表3中的“X”表示任意数据。如表3所示,4个原始像素数据组经过数据重组后获得5个重组像素数据组。
例如,如表3所示,第1个原始像素数据组为“A 7A 6A 5A 4A 3A 2A 1”,其中第一原始部分为“A 7A 6”,第二原始部分为“A 5A 4A 3A 2A 1”;第2个原始像素数据组为“B 7B 6B 5B 4B 3B 2B 1”,其中第一原始部分为“B 7B 6”,第二原始部分为“B 5B 4B 3B 2B 1”;第3个原始像素数据组为“C 7C 6C 5C 4C 3C 2C 1”,其中第一原始部分为“C 7C 6”,第二原始部分为“C 5C 4C 3C 2C 1”;第4个原始像素数据组为“D 7D 6D 5D 4D 3D 2D 1”,其中第一原始部分为“D 7D 6”,第二原始部分为“D 5D 4D 3D 2D 1”。
对上述四个原始像素数据组按照本公开的实施例提供的数据转换方法进行数据重组后获得五个重组像素数据组,如表3所示,第1个重组像素数据组由两位任意数据“XX”和第1个原始像素数据组中的第二原始部分“A 5A 4A 3A 2A 1”组成;第2个重组像素数据组由第1个原始像素数据组中的第一原始部分“A 7A 6”和第2个原始像素数据组中的第二原始部分“B 5B 4B 3B 2B 1”组成;第3个重组像素数据组由第2个原始像素数据组中的第一原始部分“B 7B 6”和第3个原始像素数据组中的第二原始部分“C 5C 4C 3C 2C 1”组成;第4个重组像素数据组由第3个原始像素数据组中的第一原始部分“C 7C 6”和第4个原始像素数据组中的第二原始部分“D 5D 4D 3D 2D 1”组成;第5个重组像素数据组由第4个原始像素数据组中的第一原始部分“D 7D 6”和五位任意数据“XXXXX”组成。
例如,在本公开的实施例提供的数据转换方法中,在每一个重组像素数据组中,除了任意数据外其它各个数据的占位与该数据在重组前的原始像素数据组中的占位相同。需要说明的是,在本公开的实施例中,“占位”表示某一位(bit)数据在重组像素数据组(或原始像素数据组)中所处的位置,例如,如表3中所示,重组前A7位于原始像素数据组“A 7A 6A 5A 4A 3A 2A 1”中的第七位,重组后A7位于重组像素数据组“A 7A 6B 5B 4B 3B 2B 1”中的第七 位,也就是说,在重组前后,A7在一个像素数据组(原始像素数据组或重组像素数据组)中的位置是保持不变的。
例如,位移位数x可以根据显示面板中的芯片所采用的信号标准来确定。下面以显示面板采用HX8861芯片为例,来说明本公开的实施例提供的上述数据转换方法。
例如,在一个示例中,一个像素一般包括RGB三个子像素,每一子像素对应8位数据,一个像素对应的原始像素数据包括28位数据,其中24位数据为三个子像素对应的数据,剩下的4位数据为控制信号对应的数据(例如,三位控制位DE、VS和HS,以及一个空位)。例如,一个像素对应的原始像素数据通过4个数据通道OLV0~OLV3进行传输,则每个数据通道传输7位数据。
例如,4个数据通道OLV0~OLV3中对应LVDS信号标准的第一时钟周期和对应HX8861芯片信号标准的第二时钟周期的映射关系如图3所示,下面以数据通道OLV3为例进行说明。例如,一个原始像素数据组按照第一时钟周期的排列为:R7、R6、空、B7、B6、G7、G6,但是将该原始像素数据组传输至HX8861芯片时,此时HX8861并不认为这是一个周期的数据,HX8861的信号标准认为循环周期(即第二时钟周期)对应的数据排列(即重组像素数据组)为空、B7、B6、G7、G6、R7、R6。并且此时的R7、R6为LVDS IP核中下一个像素的像素数据,因此在该通道上表现为第n+1个像素的原始像素数据中的R7和R6位移到第n个像素的原始像素数据中去了。其余三个信号通道OLV2、OLV1、OLV0也会出现类似的数据位移现象,且位移位数x=2。
同样以数据通道OLV3为例进行说明,如果不进行数据转换,那么从LVDS IP核输出的数据在第一时钟周期的排列为:R7、R6、空、B7、B6、G7、G6,而显示面板中的HX8861芯片收到的却是空、B7、B6、G7、G6、R7、R6,并且R7和R6是下一个周期中的数据。
采用本公开的实施例提供的数据转换方法对原始像素数据进行数据重组后,虽然HX8861芯片收到的重组像素数据仍然是空、B7、B6、G7、G6、R7、R6,但是由于第n个重组像素数据组中的第一重组部分由第n-1个原始像素数据组中的第一原始部分组成,第n个重组像素数据组中的第二重组部分由第n个原始像素数据组中的第二原始部分组成,因此此时的R7和R6 还是属于第n个原始像素数据组的,从而可以避免发生显示异常现象。
因此,采用本公开的实施例提供的数据转换方法,可以根据预先确定的位移位数x,在LVDS IP核输出LVDS信号之前,对显示面板中的至少一行像素对应的原始像素数据进行数据重组,这样根据重组后获得的重组像素数据进行LVDS转换后再进行显示,从而可以解决画面异常的问题。
例如,在本公开的实施例提供的数据转换方法中,在任一一个数据通道中,数据转换方法还包括:依次接收N个原始像素数据组,且在接收第n个原始像素数据组时缓存第n-1个原始像素数据组中的至少x位数据,x为第一原始部分包括的数据位数。在任一一个数据通道中,对显示面板中的至少一行像素对应的原始像素数据进行数据重组以获得重组像素数据包括:将当前缓存的第n-1个原始像素数据组中的第一原始部分和当前接收的第n个原始像素数据组中的第二原始部分进行重组,以形成第n个重组像素数据组。
需要说明的是,由于第n个重组像素数据组是由第n-1个原始像素数据组中的第一原始部分(x位数据)组成,所以在缓存第n-1个原始像素数据组时,可以不需要缓存第n-1个原始像素数据组的全部数据,例如只缓存第n-1个原始像素数据中的第一原始部分(即x位数据),采用这种缓存方式可以节省缓存空间,从而进一步降低成本。
例如,在任一一个数据通道中,对显示面板中的至少一行像素对应的原始像素数据进行数据重组以获得重组像素数据还包括:在接收第一个原始像素数据组时,将x位任意数据与第一个原始像素数据组中的第二原始部分进行重组,以形成第一个重组像素数据组。
例如,在任一一个数据通道中,对显示面板中的至少一行像素对应的原始像素数据进行数据重组以获得重组像素数据还包括:在接收最后一个原始像素数据组后,缓存最后一个原始像素数据组中的至少x位数据,并将缓存的最后一个原始像素数据组中的第一原始部分与y位任意数据进行重组,以形成最后一个重组像素数据组;y为第二原始部分包括的数据位数。例如,在原始像素数据组包括7位数据且位移位数x为2的情形中,y的取值为5。
例如,如图4所示,在任一一个数据通道中,本公开的实施例提供的数据转换方法包括如下操作。
S401:依次接收N个原始像素数据组;
S402:在接收第一个原始像素数据组时,将x位任意数据与第一个原始 像素数据组中的第二原始部分(y位数据)进行重组,以形成第一个重组像素数据组;
S403:在接收第n个原始像素数据组时缓存第n-1个原始像素数据组中的至少x位数据;
S404:将当前缓存的第n-1个原始像素数据组中的第一原始部分和当前接收的第n个原始像素数据组中的第二原始部分进行重组,以形成第n个重组像素数据组;以及
S405:在接收最后一个原始像素数据组后,缓存最后一个原始像素数据组中的至少x位数据,并将缓存的最后一个原始像素数据组中的第一原始部分与y位任意数据进行重组,以形成最后一个重组像素数据组。
例如,在本公开的实施例提供的数据转换方法中,原始像素数据组的缓存可以在接收原始像素数据组后延迟一个第一时钟周期进行缓存。对应的时序图如图5所示,其中CLK为第一时钟周期信号,一个第一时钟周期用于接收一个原始像素数据组,DE为控制信号,DE为高时开始接收原始像素数据,datain表示接收的原始像素数据,datain_l表示缓存的原始像素数据,data表示重组后的重组像素数据。另外,datain、datain_l和data的关系如下表4所示。

例如,在任一一个数据通道中,对显示面板中的至少一行像素对应的原始像素数据进行数据重组以获得重组像素数据还包括:将x位任意数据与缓存的第一个原始像素数据组中的第二原始部分进行重组,以形成第一个重组像素数据组。
例如,在任一一个数据通道中,对显示面板中的至少一行像素对应的原始像素数据进行数据重组以获得重组像素数据还包括:将缓存的最后一个原始像素数据组中的第一原始部分与y位任意数据进行重组,以形成最后一个重组像素数据组;y为第二原始部分包括的数据位数。

例如,在本公开的实施例提供的数据转换方法中,按照显示面板的驱动扫描顺序,对显示面板中的每一行像素对应的原始像素数据分别都进行数据重组。
例如,一个显示面板包括多行像素,可以按照显示面板的驱动扫描顺序,依次对显示面板中的每一行像素对应的原始像素数据进行数据重组。需要说明的是,本公开的实施例包括但不限于此,例如还可以采用任意顺序对显示面板中的多行像素对应的原始像素数据进行数据重组,待显示面板包括的所有像素对应的原始像素数据都重组完成后,再进行显示操作。
本公开的至少一实施例还提供一种显示方法,如图11所示,该显示方法包括如下操作。

例如,原始像素数据通过至少一个数据通道按照第一时钟周期进行传输,重组像素数据通过至少一个数据通道按照不同于第一时钟周期的第二时钟周期进行传输。关于数据重组的描述可以参考上述关于数据转换方法的实施例中的相应描述,这里不再赘述。
基于同一构思,本公开的实施例还提供一种数据转换装置,例如,该数据转换装置可以用于显示面板显示。由于该数据转换装置解决问题的原理与前述数据转换方法相似,因此该数据转换装置的实施可以参见前述数据转换方法的实施,重复之处不再赘述。

例如,如图10所示,该数据转换装置集成在现场可编程门阵列上。这样现场可编程门阵列上的接收电路接收信号源发出的原始像素数据,并通过缓存电路进行缓存,重组电路根据缓存的原始像素数据进行重组后获得重组像素数据,然后再由信号转换电路(例如,LVDS IP核)将重组像素数据转换为低压差分信号后发送至显示面板,例如,显示面板中的时序控制器(Timing Controller,TCON)接收该低压差分信号,显示面板根据接收到的低压差分信号进行显示。
