Description

曲面液晶显示面板及曲面液晶显示装置 技术领域
本发明涉及显示器领域，特别是涉及一种曲面液晶显示面板及曲面液晶显示装置。
 背景技术
曲面液晶显示装置（Curved TFT-LCD，Thin Film Transistor Liquid Crystal Display)是一种曲面结构的液晶显示装置，其包括曲面结构的彩膜基板11和曲面结构的阵列基板12。该彩膜基板11可包括黑色矩阵111、红色彩膜112、绿色彩膜113以及蓝色彩膜114。请参照图1，图1为现有的曲面液晶显示装置的结构示意图以及局部结构图。
该彩膜基板11上通常会制作一层黑色矩阵111（BM，Black matrix)避免混色和漏光。而对于目前的曲面液晶显示装置，通常采取先做成平面结构，再对该平面结构进行弯曲处理。该平面结构进行弯曲的过程中，可能会导致彩膜基板和阵列基板的相对错位，如图1所示，彩膜基板的左侧相对阵列基板向左侧偏移，彩膜基板的右侧相对阵列基板向右侧偏移。
当曲面结构的弯曲程度较大时，彩膜基板相对阵列基板的偏移量较大，这样液晶显示装置会出现色偏现象。即当左侧的液晶显示面板显示绿色画面时，在绿色画面的右侧会出现蓝色区域（图1的A区域），即阵列基板12的绿色像素同时覆盖到彩膜基板11的绿色彩膜113和蓝色彩膜114）；当右侧的液晶显示面板显示绿色画面时，在绿色画面的左侧会出现红色区域（图1的B区域），即阵列基板12的绿色像素同时覆盖到彩膜基板11的绿色彩膜113和红色彩膜112；严重影响曲面液晶显示装置的画面显示质量。

 附图说明
图1为现有的曲面液晶显示装置的结构示意图以及局部结构图；
图2为本发明的曲面液晶显示面板的第一优选实施例的结构示意图以及局部结构图；
图3为本发明的曲面液晶显示面板的第二优选实施例的结构示意图以及局部结构图；
图4为本发明的曲面液晶显示面板的第三优选实施例的结构示意图以及局部结构图。
 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
在图中，结构相似的单元是以相同标号表示。
请参照图2，图2为本发明的曲面液晶显示面板的第一优选实施例的结构示意图以及局部结构图。本优选实施例的曲面液晶显示面20板包括曲面结构的彩膜基板21以及曲面结构的阵列基板22，彩膜基板21和阵列基板22的具体结构如图2的上部分所示。
如图2的下部分所示，彩膜基板21包括黑色矩阵211以及彩膜色阻，彩膜色阻可包括红色彩膜212、绿色彩膜213以及蓝色彩膜214。阵列基板22与彩膜基板21相对设置，其包括像素电极221、数据线（图中未示出）以及扫描线（图中未示出）。阵列基板22的像素电极221与彩膜基板21的彩膜色阻一一对应，从而每个像素可通过彩膜基板21发出红、绿、蓝三色光。
由于曲面结构的阵列基板22和曲面结构的彩膜基板21相对设置，因此如图2所示，彩膜基板21的两侧的彩膜色阻与阵列基板22上对应的像素电极221发生了偏移现象。位于曲面液晶显示面板20左侧的彩膜基板21的彩膜色阻相对相应的像素电极221向左偏移，位于曲面液晶显示面板20右侧的彩膜基板21的彩膜色阻相对相应的像素电极221向右偏移。
为了避免色偏现象的发生，本优选实施例的曲面液晶显示面板20的彩膜基板21沿彩膜基板21的长度方向设置有两个区域，这两区域沿彩膜基板21的中心轴对称。由于彩膜基板21的最左侧的彩膜色阻与相应的像素电极221的偏移量、和彩膜基板21的最右侧的彩膜色阻与相应的像素电极221的偏移量最大，因此彩膜基板21的左侧的区域，根据彩膜基板21最左侧的彩膜色阻与阵列基板22最左侧的像素电极221之间的偏移量（该区域内的最大偏移量），设置该区域内的黑色矩阵211的宽度，以使得该区域的曲面液晶显示面板20不会产生色偏现象。彩膜基板21的右侧的区域根据彩膜基板21最右侧的彩膜色阻与阵列基板22最右侧的像素电极221之间的偏移量（该区域内的最大偏移量），设置该区域内的黑色矩阵211的宽度，以使得该区域的曲面液晶显示面板20不会产生色偏现象。
本优选实施例的曲面液晶显示面板20使用时，彩膜基板21的左侧的区域以及彩膜基板21的右侧的区域均设置有相应宽度的黑色矩阵211，使得阵列基板22的任何一个像素电极221对应的像素的出射光不会从两个相邻的彩膜色阻射出，从而避免了色偏现象的产生。同时由于彩膜基板21和阵列基板22是对称设置的，彩膜基板21的左侧区域和右侧区域的黑色矩阵211的宽度也为对称设置，即左侧区域和右侧区域的黑色矩阵211的位置设置有所不同，但是黑色矩阵211的总面积是相同的，因此曲面液晶显示面板20的左右侧的亮度一致，不会出现某个区域亮度的突变。
本优选实施例的曲面液晶显示面板通过不同区域设置不同宽度的黑色矩阵，避免了色偏现象的产生。
请参照图3，图3为本发明的曲面液晶显示面板的第二优选实施例的结构示意图以及局部结构图。本优选实施例的曲面液晶显示面板30包括曲面结构的彩膜基板31以及曲面结构的阵列基板32，彩膜基板31和阵列基板32的具体结构如图3的上部分所示。
如图3的下部分所示，彩膜基板31包括黑色矩阵311以及彩膜色阻，彩膜色阻可包括红色彩膜312、绿色彩膜313以及蓝色彩膜314。阵列基板32与彩膜基板31相对设置，其包括像素电极321、数据线（图中未示出）以及扫描线（图中未示出）。阵列基板32的像素电极321与彩膜基板31的彩膜色阻一一对应，从而每个像素可通过彩膜基板31发出红、绿、蓝三色光。
由于曲面结构的阵列基板32和曲面结构的彩膜基板31相对设置，因此如图3所示，彩膜基板31的两侧的彩膜色阻与阵列基板32上对应的像素电极321发生了偏移现象。位于曲面液晶显示面板30左侧的彩膜基板31的彩膜色阻相对相应的像素电极321向左偏移，位于曲面液晶显示面板30右侧的彩膜基板31的彩膜色阻相对相应的像素电极321向右偏移。
为了避免色偏现象的产生，本优选实施例的曲面液晶显示面板30的彩膜基板31沿彩膜基板31的长度方向设置有三个区域，左侧区域、中间区域以及右侧区域，左侧区域和右侧区域对称设置在中间区域的左侧和右侧。由于彩膜基板31的最左侧的彩膜色阻与相应的像素电极321的偏移量、和彩膜基板31的最右侧的彩膜色阻与相应的像素电极321的偏移量最大，因此彩膜基板31的左侧区域，根据彩膜基板31最左侧的彩膜色阻与阵列基板32最左侧的像素电极321之间的偏移量（该区域内的最大偏移量），设置左侧区域内的黑色矩阵311的宽度，以使得左侧区域的曲面液晶显示面板30不会产生色偏现象。彩膜基板31的右侧区域，根据彩膜基板31最右侧的彩膜色阻与阵列基板32最右侧的像素电极321之间的偏移量（该区域内的最大偏移量），设置右侧区域内的黑色矩阵311的宽度，以使得右侧区域的曲面液晶显示面板30不会产生色偏现象。
由于彩膜基板31的中间区域中的彩膜色阻与阵列基板32的对应像素电极321之间的偏移量较小，中间区域的曲面液晶显示面板30不会产生色偏现象，因此中间区域的黑色矩阵311的宽度不需要根据彩膜色阻和对应的像素电极321的偏移量进行调整。
因此本优选实施例的曲面液晶显示面板30的彩膜基板31的左侧区域的黑色矩阵311的宽度大于彩膜基板31的中间区域的黑色矩阵311的宽度，彩膜基板31的右侧区域的黑色矩阵311的宽度也大于彩膜基板31的中间区域的黑色矩阵311的宽度。
本优选实施例的曲面液晶显示面板30使用时，彩膜基板31的左侧区域以及彩膜基板31的右侧区域均设置有相应宽度的黑色矩阵311，使得阵列基板32的任何一个像素电极321对应的像素的出射光不会从两个相邻的彩膜色阻射出，从而避免了色偏现象的产生。同时彩膜基板31的中间区域的黑色矩阵311的宽度较小，可以进一步提高曲面液晶显示面板30的开口率，提高曲面液晶显示面板30的显示效率。
本优选实施例的曲面液晶显示面板在第一优选实施例的基础上通过设置较宽黑色矩阵的中间区域，进一步提高了曲面液晶显示面板的开口率以及显示效率。
请参照图4，图4为本发明的曲面液晶显示面板的第三优选实施例的结构示意图以及局部结构图。本优选实施例的曲面液晶显示面板40包括曲面结构的彩膜基板41以及曲面结构的阵列基板42，彩膜基板41和阵列基板42的具体结构如图4的上部分所示。
如图4的下部分所示，彩膜基板41包括黑色矩阵411以及彩膜色阻，彩膜色阻可包括红色彩膜412、绿色彩膜413以及蓝色彩膜414。阵列基板42与彩膜基板41相对设置，其包括像素电极421、数据线（图中未示出）以及扫描线（图中未示出）。阵列基板42的像素电极421与彩膜基板41的彩膜色阻一一对应，从而每个像素可通过彩膜基板41发出红、绿、蓝三色光。
由于曲面结构的阵列基板42和曲面结构的彩膜基板41相对设置，因此如图4所示，彩膜基板41的两侧的彩膜色阻与阵列基板42上对应的像素电极421发生了偏移现象。位于曲面液晶显示面板40左侧的彩膜基板41的彩膜色阻相对相应的像素电极421向左偏移，位于曲面液晶显示面板40右侧的彩膜基板41的彩膜色阻相对相应的像素电极421向右偏移。
为了避免色偏现象的产生，本优选实施例的曲面液晶显示面板40的彩膜基板41沿彩膜基板41的长度方向设置有五个区域，两个左侧区域、中间区域以及两个右侧区域，两个左侧区域和两个右侧区域对称设置在中间区域的左侧和右侧。由于彩膜基板41的左侧区域的区域内最左侧的彩膜色阻与相应的像素电极421的偏移量、和彩膜基板41的右侧区域的区域内最右侧的彩膜色阻与相应的像素电极421的偏移量最大，因此彩膜基板41的左侧区域，根据彩膜基板41的左侧区域的区域内最左侧的彩膜色阻与相应的像素电极421之间的偏移量（该区域内的最大偏移量），设置左侧区域内的黑色矩阵411的宽度，以使得左侧区域的曲面液晶显示面板40不会产生色偏现象。彩膜基板41的右侧区域，根据彩膜基板41的右侧区域的区域内最右侧的彩膜色阻与相应的像素电极421之间的偏移量（该区域内的最大偏移量），设置右侧区域内的黑色矩阵411的宽度，以使得右侧区域的曲面液晶显示面板40不会产生色偏现象。
由于彩膜基板41的中间区域中的彩膜色阻与阵列基板42的对应像素电极421之间的偏移量较小，中间区域的曲面液晶显示面板40不会产生色偏现象，因此中间区域的黑色矩阵411的宽度不需要根据彩膜色阻和对应的像素电极421的偏移量进行调整。
因此本优选实施例的曲面液晶显示面板40的彩膜基板41的左侧区域的黑色矩阵411的宽度大于彩膜基板41的中间区域的黑色矩阵411的宽度，彩膜基板41的右侧区域的黑色矩阵411的宽度也大于彩膜基板41的中间区域的黑色矩阵411的宽度。
距离中间区域较远的左侧区域的黑色矩阵411的宽度大于距离中间区域较近的左侧区域的黑色矩阵411的宽度；距离中间区域较远的右侧区域的黑色矩阵411的宽度大于距离中间区域较近的右侧区域的黑色矩阵411的宽度。
本优选实施例的曲面液晶显示面板40使用时，彩膜基板41的左侧区域以及彩膜基板41的右侧区域均设置有相应宽度的黑色矩阵411，使得阵列基板42的任何一个像素电极421对应的像素的出射光不会从两个相邻的彩膜色阻射出，从而避免了色偏现象的产生。同时距离中间区域较近的左侧区域以及右侧区域的黑色矩阵411的宽度较小（与第一优选实施例中的左侧区域和右侧区域的黑色矩阵的宽度比较），可以进一步提高曲面液晶显示面板40的开口率，提高曲面液晶显示面板40的显示效率。
本优选实施例的曲面液晶显示面板在第二优选实施例的基础上通过设置多个左侧区域和右侧区域，进一步提高了曲面液晶显示面板的开口率以及显示效率。
本发明还提供一种曲面液晶显示装置，该曲面液晶显示装置包括背光模块以及曲面液晶显示面板，该背光模块包括光源以及导光板，光源用于提供出射光线，导光板用于将出射光线传导至曲面液晶显示面板上。曲面液晶显示面板包括曲面结构的彩膜基板以及曲面结构的阵列基板。
彩膜基板包括黑色矩阵以及彩膜色阻，彩膜色阻可包括红色彩膜、绿色彩膜以及蓝色彩膜。阵列基板与彩膜基板相对设置，其包括像素电极、数据线以及扫描线。阵列基板的像素电极与彩膜基板的彩膜色阻一一对应，从而每个像素可通过彩膜基板发出红、绿、蓝三色光。
由于曲面结构的阵列基板和曲面结构的彩膜基板相对设置，彩膜基板的两侧的彩膜色阻与阵列基板上对应的像素电极发生了偏移现象。位于曲面液晶显示面板左侧的彩膜基板的彩膜色阻相对相应的像素电极向左偏移，位于曲面液晶显示面板右侧的彩膜基板的彩膜色阻相对相应的像素电极向右偏移。
为了避免色偏现象的产生，本优选实施例的曲面液晶显示面板的彩膜基板沿彩膜基板的长度方向设置有多个区域，根据每个区域内彩膜基板相对阵列基板的最大偏移量，设置相应的区域内的黑色矩阵的宽度，以使得相应的区域的曲面液晶显示面板不产生色偏现象。
同时由于不同区域的黑色矩阵的宽度不同，因此不同区域的亮度会有所差异，本优选实施例的曲面液晶显示装置的背光模块的导光板根据各区域内的黑色矩阵的宽度，对各区域对应的出射光线进行亮度补偿，从而使得区域的显示亮度最终趋于一致。
本发明的曲面液晶显示面板及曲面液晶显示装置通过不同区域设置不同宽度的黑色矩阵，避免了色偏现象的产生；解决了现有的曲面液晶显示面板及曲面液晶显示装置由于彩膜基板和阵列基板之间的相对偏移，导致易产生色偏现象，从而影响液晶显示装置的显示品质的技术问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
