Description

显示面板的画面压缩方法及画面压缩装置 技术领域
本发明属于显示技术领域，具体地讲，涉及一种显示面板的画面压缩方法及画面压缩装置。
背景技术
随着光电与半导体技术的演进，也带动了平板显示器(Flat Panel Display)的蓬勃发展，而在诸多平板显示器中，液晶显示器(Liquid Crystal Display，LCD)因具有高空间利用效率、低消耗功率、无辐射以及低电磁干扰等诸多优越特性，已被应用于生产生活的各个方面。
在液晶显示器的组装过程中，因各面板生产商生产的显示面板(即液晶面板)的显示区(Active Area，AA区)的区域面积各不相同，因此导致用于将液晶面板和背光模块压合组装在一起的机构外框的兼容性较低。例如，某A生产商生产的显示面板的显示区的区域面积大于某B生产商生产的显示面板的显示区的区域面积，这样当利用压合组装某B生产商生产的显示面板的机构外框来压合组装某A生产商生产的显示面板时，某A生产商生产的显示面板的显示区的边缘将被机构外框遮挡，从而导致利用某A生产商生产的显示面板组装形成的液晶显示器显示的画面不完全。

附图说明
通过结合附图进行的以下描述，本发明的实施例的上述和其它方面、特点 和优点将变得更加清楚，附图中：
图1是根据本发明的是实施例的液晶面板被机构外框压合的示意图；
图2是根据本发明的实施例的显示面板的画面压缩方法的流程图；
图3是根据本发明的实施例的显示面板的画面压缩装置的模块单元图。
具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
在本实施例中，以分辨率为1920×1080的液晶面板作为显示面板的一示例对本发明的显示面板的画面压缩方法及画面压缩装置进行描述说明。当然，应当理解的是，液晶面板的分辨率并不以1920×1080为限。此外，作为本发明的另一实施方式，也可以采用有机发光显示面板(即OLED面板)作为示例。
图1是根据本发明的是实施例的液晶面板被机构外框压合的示意图。
参照图1，根据本发明的实施例的液晶面板10包括显示区(Active Area，即AA区)AA以及环绕显示区AA的非显示区(未示出)。在显示区AA中，阵列排布设置有若干子像素(Sub-pixel)PX。在本实施例中，子像素PX可例如是红色子像素、蓝色子像素或者绿色子像素。此外，本实施例中，由红色子像素、绿色子像素和蓝色子像素构成一像素。
当机构外框20压合液晶面板10时，由于机构外框20遮挡非显示区以及显示区AA的边缘，因此会将位于显示区AA边缘的子像素PX显示的画面遮挡。
在本实施例中，由于液晶面板10的分辨率为1920×1080，因此在显示区AA中阵列排布1080行×5760(1920×3)列子像素PX。而作为一个示例，机构外框20遮挡了显示区AA中的第1列、第2列、第5759列、第5760列、 第1行以及第1080行的子像素PX。这样，为了使显示区AA未被机构外框20遮挡的区域显示的画面的长宽比与显示区AA显示的画面的长宽比一致，需要对显示区AA显示的画面进行压缩，以下将详细描述压缩过程。
图2是根据本发明的实施例的显示面板的画面压缩方法的流程图。
参照图1和图2，在步骤S110中，获取液晶面板10的显示区(Active Area，AA区)AA中被遮挡的子像素PX的数量。
具体地，实现步骤S110的具体方法包括：
获取液晶面板10的显示区AA被遮挡的像素行区域和像素列区域(图1中以斜线阴影示出)的宽度，且获取液晶面板10显示区AA中的子像素PX的长度和宽度。也就是说，获取被遮挡的第一像素列区域(其包括第1列子像素PX和第2列子像素PX所占的区域)的宽度W1、被遮挡的第二像素列区域(其包括第5759列子像素PX和第5760列子像素PX所占的区域)的宽度W2、被遮挡的第一像素行区域(其包括第1行子像素PX所占的区域)的宽度L1、被遮挡的第二像素行区域(其包括第1080行子像素PX所占的区域)的宽度L2，并且获取子像素PX的长度L和宽度W。
根据被遮挡的像素行区域的宽度与子像素PX的宽度计算出被遮挡的像素行的数量，并且根据被遮挡的像素列区域的宽度与子像素PX的长度计算出被遮挡的像素列的数量。也就是说，利用被遮挡的第一像素列区域的宽度W1除以子像素PX的宽度W，以计算出被遮挡的像素列的数量，即第1列和第2列共两列；利用被遮挡的第二像素列区域的宽度W2除以子像素PX的宽度W，以计算出被遮挡的像素列的数量，即第5759列和第5760列共两列；利用被遮挡的第一像素行区域的宽度L1除以子像素PX的长度L，以计算出被遮挡的像素行的数量，即第1行共一行；利用被遮挡的第二像素行区域的宽度L2除以子像素PX的长度L，以计算出被遮挡的像素行的数量，即第1080行共一行。
根据计算出的被遮挡的像素列和像素行的数量以及液晶面板10的分辨率计算出被遮挡的子像素PX的数量。也就是说，液晶面板10的分辨率为1920×1080，即在显示区AA中，每列子像素PX的数量为1080个，每行子像素PX的数量为5760个。由于一行子像素PX与一列子像素PX的交汇处重合 一个子像素PX，因此需要减去重合的这个子像素PX。那么，两行四列子像素PX重合8个子像素PX，这样被遮挡的子像素PX的数量为15832(1080×4+5760×2-8)个。
在步骤S120中，将与显示区AA中被遮挡的子像素PX的数量相同的像素数据删除。
一般而言，显示区AA需显示画面时，需要提供与显示区AA中具有的子像素PX数量相同的像素数据，每个像素数据给到对应的一个子像素PX，从而子像素PX根据对应的像素数据进行显示。这样，在本实施例中，提供给显示区AA中的子像素PX的像素数据的数量为1920×1080个。由于被遮挡的子像素PX的数量为15832个，因此需要从1920×1080个像素数据中删除15832个。
具体地，实现步骤S120的方法包括：
显示面板的时序控制器或者显示面板的SoC(System-on-a-Chip)对每一像素行上相邻的两个子像素PX对应的像素数据进行比较。这里，优选地，每个子像素PX仅被比较一次，但本发明并不限制于此。也就是说，在同一像素行上，按照两两子像素PX的顺序对它们对应的像素数据进行比较。
当每一像素行上相邻的两个子像素PX对应的像素数据相同时，显示面板的时序控制器或者显示面板的SoC(System-on-a-Chip)抽取并删除其中一个像素数据，直至抽取并删除的像素数据的数量为11520(5760×2)或者11512(5760×2-8)时，即抽取并删除的像素数据的数量等于位于被遮挡的像素行上的子像素PX的数量时，停止上述比较、删除过程。若抽取并删除的像素数据的数量小于11520或者11512，则继续进行上述比较、删除过程。这样，显示面板的时序控制器或者显示面板的SoC(System-on-a-Chip)将数量与位于被遮挡的像素行上的子像素PX的数量相等的像素数据抽取并删除。
显示面板的时序控制器或者显示面板的SoC(System-on-a-Chip)对每一像素列上相邻的两个子像素PX对应的像素数据进行比较。这里，优选地，每个子像素PX仅被比较一次，但本发明并不限制于此。也就是说，在同一像素列上，按照两两子像素PX的顺序对它们对应的像素数据进行比较。
当每一像素列上相邻的两个子像素PX对应的像素数据相同时，显示面板的时序控制器或者显示面板的SoC(System-on-a-Chip)抽取并删除其中一个像素数据，直至抽取并删除的像素数据的数量为4312(1080×4-8)或者4320(1080×4)时，即抽取并删除的像素数据的数量等于位于被遮挡的像素列上的子像素PX的数量时，停止上述比较、删除过程。若抽取并删除的像素数据的数量小于4312或者4320，则继续进行上述比较、删除过程。这样，显示面板的时序控制器或者显示面板的SoC(System-on-a-Chip)将数量与位于被遮挡的像素列上的子像素PX的数量相等的像素数据抽取并删除。
在步骤S130中，对未被删除的像素数据进行整合处理，使未被删除的像素数据与显示区AA中未被遮挡的子像素PX一一对应。
具体地，实现步骤S130的方法包括：
将与显示区AA中被遮挡的子像素PX的数量相同的虚拟数据(dummy)或者黑画面数据插入未被删除的像素数据中。也就是说，在未被删除的像素数据中插入15832个虚拟数据(dummy)或者黑画面数据。
对未被删除的像素数据以及插入的虚拟数据信号或者黑画面数据进行整合处理，使插入的虚拟数据信号或者黑画面数据与显示区AA中被遮挡的子像素PX一一对应，且使未被删除的像素数据与显示区AA中未被遮挡的子像素PX一一对应。也就是说，插入的15832个虚拟数据(dummy)或者黑画面数据与15832个被遮挡的子像素PX一一对应。
在步骤S140中，将整合处理后的未被删除的像素数据提供给显示区AA中未被遮挡的子像素PX，从而显示区AA中未被遮挡的子像素PX显示的画面的长宽比与显示区AA中的所有子像素PX显示的画面的长宽比一致。
具体地，将插入的每个个虚拟数据(dummy)或者黑画面数据提供给对应的被遮挡的子像素PX，以使被遮挡的子像素PX显示虚拟画面或者黑画面；而未被删除的像素数据提供给显示区AA中未被遮挡的子像素PX，由于删除的像素数据为重复相同的像素数据，因此未被删除的像素数据与原有的像素数据(即删除的像素数据+未被删除的像素数据)所表达的画面一致，从而能够使显示区AA中未被遮挡的子像素PX显示的画面的长宽比与显示区AA中的所 有子像素PX显示的画面的长宽比一致。
图3是根据本发明的实施例的显示面板的画面压缩装置的模块单元图。
参照图1和图3，根据本发明的实施例的显示面板的画面压缩装置包括：子像素数量获取模块310、像素数据删除模块320、数据整合处理模块330、输出模块340。应当说明的是，根据本发明的实施例的显示面板的画面压缩装置可被集成于显示面板的时序控制器或者显示面板的SoC(System-on-a-Chip)中，但本发明并不限制于此。
子像素数量获取模块310被配置为获取液晶面板10的显示区(Active Area，AA区)AA中被遮挡的子像素PX的数量。
在本实施例中，子像素数量获取模块310包括：尺寸获取单元311、行列数量计算单元312、子像素数量计算单元313。
具体地，尺寸获取单元311被配置为获取液晶面板10的显示区AA被遮挡的像素行区域和像素列区域的宽度，且被配置为获取液晶面板10显示区AA中的子像素PX的长度和宽度。
也就是说，尺寸获取单元311获取被遮挡的第一像素列区域(其包括第1列子像素PX和第2列子像素PX所占的区域)的宽度W1、被遮挡的第二像素列区域(其包括第5759列子像素PX和第5760列子像素PX所占的区域)的宽度W2、被遮挡的第一像素行区域(其包括第1行子像素PX所占的区域)的宽度L1、被遮挡的第二像素行区域(其包括第1080行子像素PX所占的区域)的宽度L2，并且尺寸获取单元311获取子像素PX的长度L和宽度W。
行列数量计算单元312被配置为根据被遮挡的像素行区域的宽度与子像素PX的宽度计算出被遮挡的像素行的数量，并且被配置为根据被遮挡的像素列区域的宽度与子像素PX的长度计算出被遮挡的像素列的数量。
也就是说，行列数量计算单元312利用被遮挡的第一像素列区域的宽度W1除以子像素PX的宽度W，以计算出被遮挡的像素列的数量，即第1列和第2列共两列。行列数量计算单元312利用被遮挡的第二像素列区域的宽度W2除以子像素PX的宽度W，以计算出被遮挡的像素列的数量，即第5759列 和第5760列共两列。行列数量计算单元312利用被遮挡的第一像素行区域的宽度L1除以子像素PX的长度L，以计算出被遮挡的像素行的数量，即第1行共一行。行列数量计算单元312利用被遮挡的第二像素行区域的宽度L2除以子像素PX的长度L，以计算出被遮挡的像素行的数量，即第1080行共一行。
子像素数量计算单元313被配置为根据计算出的被遮挡的像素列和像素行的数量以及液晶面板10的分辨率计算出被遮挡的子像素PX的数量。
也就是说，液晶面板10的分辨率为1920×1080，即在显示区AA中，每列子像素PX的数量为1080个，每行子像素PX的数量为5760个。由于一行子像素PX与一列子像素PX的交汇处重合一个子像素PX，因此需要减去重合的这个子像素PX。那么，两行四列子像素PX重合8个子像素PX，这样被遮挡的子像素PX的数量为15832(1080×4+5760×2-8)个。
像素数据删除模块320被配置为将与显示区AA中被遮挡的子像素PX的数量相同的像素数据删除。
一般而言，显示区AA需显示画面时，需要提供与显示区AA中具有的子像素PX数量相同的像素数据，每个像素数据给到对应的一个子像素PX，从而子像素PX根据对应的像素数据进行显示。这样，在本实施例中，提供给显示区AA中的子像素PX的像素数据的数量为1920×1080个。由于被遮挡的子像素PX的数量为15832个，因此像素数据删除模块320需要从1920×1080个像素数据中删除15832个。
在本实施例中，像素数据删除模块320包括：第一比较单元321、第一删除单元322、第二比较单元323、第二删除单元324。
具体地，第一比较单元321被配置为对每一像素行上相邻的两个子像素PX对应的像素数据进行比较。这里，优选地，第一比较单元321仅对每个子像素PX仅比较，但本发明并不限制于此。也就是说，在同一像素行上，第一比较单元321按照两两子像素PX的顺序对它们对应的像素数据进行比较。
第一删除单元322被配置为当每一像素行上相邻的两个子像素PX对应的像素数据相同时，删除其中一个像素数据。
直至第一删除单元322删除的像素数据的数量为11520(5760×2)或者11512(5760×2-8)时，即删除的像素数据的数量等于位于被遮挡的像素行上的子像素PX的数量时，停止上述比较、删除过程。若第一删除单元322删除的像素数据的数量小于11520或者11512，则继续进行上述比较、删除过程。
第二比较单元323被配置为对每一像素列上相邻的两个子像素PX对应的像素数据进行比较。这里，优选地，第二比较单元323对每个子像素PX比较一次，但本发明并不限制于此。也就是说，在同一像素列上，第二比较单元323按照两两子像素PX的顺序对它们对应的像素数据进行比较。
第二删除单元324被配置为当每一像素列上相邻的两个子像素PX对应的像素数据相同时，删除其中一个像素数据。
直至第二删除单元324删除的像素数据的数量为4312(1080×4-8)或者4320(1080×4)时，即第二删除单元324删除的像素数据的数量等于位于被遮挡的像素列上的子像素PX的数量时，停止上述比较、删除过程。若第二删除单元324删除的像素数据的数量小于4312或者4320，则继续进行上述比较、删除过程。
数据整合处理模块330被配置为对未被删除的像素数据进行整合处理，使未被删除的像素数据与显示区AA中未被遮挡的子像素PX一一对应。
在本实施例中，数据整合处理模块330包括：数据插入单元331、数据整合单元332。
具体地，数据插入单元331被配置为将与显示区AA中被遮挡的子像素PX的数量相同的虚拟数据(dummy)或者黑画面数据插入未被删除的像素数据中。也就是说，数据插入单元331在未被删除的像素数据中插入15832个虚拟数据(dummy)或者黑画面数据。
数据整合单元332被配置为对整合处理后的未被删除的像素数据以及插入的虚拟数据信号或者黑画面数据进行整合处理，使插入的虚拟数据信号或者黑画面数据与显示区AA中被遮挡的子像素PX一一对应，且使未被删除的像素数据与显示区AA中未被遮挡的子像素PX一一对应。
也就是说，数据整合单元332插入的15832个虚拟数据(dummy)或者黑画面数据与15832个被遮挡的子像素PX一一对应。
输出模块340被配置为将未被删除的像素数据提供给显示区AA中未被遮挡的子像素PX，从而显示区AA中未被遮挡的子像素PX显示的画面的长宽比与显示区AA中的所有子像素PX显示的画面的长宽比一致。
具体地，输出模块340被配置为将插入的每个虚拟数据(dummy)或者黑画面数据提供给对应的被遮挡的子像素PX，以使被遮挡的子像素PX显示虚拟画面或者黑画面；并且输出模块340还被配置为将未被删除的像素数据提供给显示区AA中未被遮挡的子像素PX。
由于删除的像素数据为重复相同的像素数据，因此未被删除的像素数据与原有的像素数据(即删除的像素数据+未被删除的像素数据)所表达的画面一致，从而能够使显示区AA中未被遮挡的子像素PX显示的画面的长宽比与显示区AA中的所有子像素PX显示的画面的长宽比一致。
