本公开的实施例涉及一种显示面板和显示装置。
随着显示技术的不断发展,液晶显示器(Liquid Crystal Display,LCD)因其响应速度快、集成度高、功耗小等优点,已成为主流的显示装置。通常,液晶显示面板包括由阵列基板和与之对盒设置的对置基板形成的液晶盒以及填充在液晶盒中的液晶分子层。液晶显示面板通过电场使液晶分子层中液晶分子的分子排列改变,配合设置在液晶显示面板两侧的偏光片,可形成液晶光阀,从而实现显示功能。另外,配合形成在阵列基板或对置基板上的彩色滤光图案,液晶显示器可进一步实现彩色显示。
在液晶显示面板的液晶盒内,为保持保证液晶盒的盒厚(Cell Gap)在各个位置的均一性,通常在阵列基板和对置基板之间设置有具有弹性回复力的柱状隔垫物(Post Spacer,PS)。柱状隔垫物处于压缩状态并起到支撑液晶盒的作用,从而保持液晶显示面板的盒厚稳定与均一。

为了更清楚地说明本公开实施例的技术方案,下面将对实施例的附图作简单地介绍,显而易见地,下面描述中的附图仅仅涉及本公开的一些实施例,而非对本公开的限制。

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。“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。
隔垫物在液晶显示面板中起着保持保证液晶盒的盒厚(Cell Gap)在各个位置的均一性的作用,从而保持液晶显示面板的盒厚稳定与均一。然而,隔垫物也在某种程度上也制约着液晶显示面板的开口率。当液晶显示面板因外力而发生位移现象时,隔垫物会划伤设置在阵列基板或对置基板上的取向膜,导致该位置处的液晶分子无法正确配向,从而导致该液晶显示面板出现亮点或暗点等不良。为了防止上述现象的发生,通常会将黑矩阵设置地较宽,以覆盖隔垫物;然而,将黑矩阵设置地较宽会降低显示面板的开口率。
图1为一种液晶显示面板的剖面示意图。如图1所示,该液晶显示面板包括第一基板110、与第一基板110对盒设置的对置基板120以及设置在第一基板110和第二基板120之间的液晶分子层200。该液晶显示面板至少还包括设置在第二基板120面向第一基板110的一侧的取向膜129以及设置在第一基板110或第二基板120上的隔垫物130;例如,如图1所示,隔垫物130可设置在第一基板110上,隔垫物130可设置在第一基板110靠近第二基板120的一侧。取向膜129可诱导液晶分子层200中的液晶分子进行定向排列;例如,可通过摩擦工艺在取向膜129的表面形成定向沟道,从而诱导液晶分子层200中 的液晶分子进行定向排列。当该液晶显示面板显示暗态时,液晶分子层200中的液晶分子不发生偏转,光无法透过液晶显示面板。当液晶显示面板显示亮态时,液晶分子层200中的液晶分子在电场的作用下发生偏转,光可以透过液晶显示面板。并且,该液晶显示面板还可通过设置在第一基板和第二基板上的彩色滤光图案的作用,使得该液晶显示面板显示具有与该彩色滤光图案对应颜色的光。
图2为图1所示的液晶显示面板因外力而发生第一基板和第二基板相对位移的示意图。如图2所示,当该液晶显示面板因外力而发生第一基板110和第二基板120相对位移(偏移)的现象时,隔垫物130从初始位置发生位移,从而划伤取向膜129。被划伤的取向膜无法诱导液晶分子层200中的液晶分子进行定向排列,从而导致无论该显示面板显示亮态或暗态时,光可以从取向膜被划伤的位置透过液晶显示面板,从而呈现漏光等不良。为了改善上述不良,可通过增加黑矩阵的宽度来来遮盖发生隔垫物划伤的区域。然而,增加黑矩阵的宽度会带来开口率和透过率降低等不足。
本发明实施例提供一种显示面板和显示装置。该显示面板包括第一基板和与第一基板相对设置的第二基板;第一基板上设置有多个主隔垫物和多个副隔垫物,第二基板还包括多个第一凸台和多个第二凸台,主隔垫物在第二基板上的正投影与对应设置的第一凸台在第二基板上的正投影至少部分重叠,副隔垫物在第二基板上的正投影沿偏移方向与第二凸台在第二基板上的正投影距离预设距离设置。由此,该显示面板可在第一基板和第二基板发生相对位移时,副隔垫物可移动到第二凸台上,对第一基板和第二基板起到支撑作用,防止主隔垫物划伤取向膜,从而避免出现因取向膜被隔垫物划伤而导致的漏光等不良。另外,由于该显示面板可避免出现因取向膜被隔垫物划伤而导致的漏光等不良,因此该显示面板可不用额外增宽黑矩阵,从而可提高该显示面板的开口率。
下面,结合附图对本公开实施例提供的显示面板和显示装置进行详细的说明。
图3为根据本公开一实施例提供的一种显示面板的剖面示意图。如图3所示,该显示面板包括第一基板110以及与第一基板110相对设置的第二基板120;第一基板110上设置有隔垫物130,即第一基板110靠近第二基板120的一侧设置有隔垫物130,隔垫物130设置在第一基板110和第二基板120之间 以维持第一基板110和第二基板120之间的距离,即由第一基板110和第二基板120构成的液晶盒的盒厚。隔垫物130包括多个主隔垫物131和多个副隔垫物132,第二基板120还包括多个第一凸台141和多个第二凸台142。多个主隔垫物131和多个第一凸台141对应设置,主隔垫物131在第二基板120上的正投影与对应设置的第一凸台141在第二基板120上的正投影至少部分重叠,也就是说,主隔垫物131设置在对应设置的第一凸台141上。多个副隔垫物132与多个第二凸台142对应设置,副隔垫物132在第二基板120上的正投影沿偏移方向与对应设置的第二凸台142在第二基板120上的正投影距离预设距离设置。需要说明的是,上述的对应设置的第二凸台可为与副隔垫物距离最近的第二凸台;上述的偏移方向是指从第二凸台在第二基板上的正投影所在的位置到副隔垫物在第二基板上的正投影所在的位置的方向。上述的偏移方向可根据第一基板和第二基板发生相对位移的方向而确定;上述的预设距离可根据第一基板和第二基板发生相对位移的距离而确定;另外,上述的预设距离不为零。
在本实施例提供的显示面板中,多个主隔垫物131可与多个第一凸台141对应设置,并且主隔垫物131在第二基板120上的正投影与对应设置的第一凸台141在第二基板120上的正投影至少部分重叠,此时主隔垫物131可以起到维持第一基板110和第二基板120之间的距离的作用。图4为图3所示的显示面板中第一基板和第二基板发生相对位移时的剖面示意图。如图4所示,由于副隔垫物132在第二基板120上的正投影沿偏移方向与对应设置的第二凸台142在第二基板120上的正投影距离预设距离设置,当该显示面板的第一基板110和第二基板120沿与上述的偏移方向相反的反方向发生相对位移时,例如因外力导致的第一基板110和第二基板120沿与上述的偏移方向相反的方向发生相对位移时,副隔垫物132在第二基板120上的正投影与对应设置的第二凸台142在第二基板120上的正投影重叠,即副隔垫物132移动到对应设置的第二凸台142上;此时,即使主隔垫物131因第一基板110和第二基板120的相对位移而从第一凸台141滑落,副隔垫物132可移动第二凸台142并对第一基板110和第二基板120起到支撑作用,从而可避免主隔垫物划伤取向膜。
例如,在一些示例中,如图3和4所示,预设距离大于0且小于相邻两个第二凸台142之间的距离。
例如,在一些示例中,如图3和4所示,该显示面板还包括设置在第一基板110和第二基板120之间的液晶分子层200;以及取向膜129,设置在第二 基板120靠近第一基板110的一侧。取向膜129可诱导液晶分子层200中的液晶分子进行定向排列。
例如,在一些示例中,如图3所示,主隔垫物131在垂直于第二基板120的方向上的高度h1大于副隔垫物132在垂直于第二基板120的方向上的高度h2,副隔垫物132在垂直于第二基板120的方向上与第二凸台142的距离d1小于第一凸台141在垂直于第二基板120的方向上的高度d2。当发生相对位移时,至少一部分副隔垫物132落在第二凸台142上时,由于d1小于d2,当副隔垫物132落到第二凸台142上时,主隔垫物131与第一基板110的距离大于零。从而该显示面板可保证当主隔垫物131因第一基板110和第二基板120的相对位移而从第一凸台141滑落时,副隔垫物132可移动第二凸台142并避免主隔垫物131划伤取向膜129。例如,在一些示例中,在该显示面板中,除了上述副隔垫物之外,还可设置通常的副隔垫物和对应设置的第二凸台,上述的通常的副隔垫物与对应设置的第二凸台在在第二基板上的正投影至少部分重叠,用于在显示面板的第一基板和第二基板未发生位移时,辅助维持第一基板和第二基板的距离。
例如,在一些示例中,在第一凸台或第二凸台所在的区域内,第二基板包括薄膜晶体管。也就是说,当第二基板为阵列基板时,第一凸台或第二凸台可利用第二基板上的薄膜晶体管自然形成的段差形成。当然,本公开实施例包括但不限于此,第一凸台或第二凸台也可通过图案化其他层结构而形成。
例如,在一些示例中,第一凸台和第二凸台沿垂直于第二基板的方向上的高度相等。
例如,在一些示例中,预设距离为第一基板和第二基板受外力的偏移距离。
图5为根据本公开一实施例提供的另一种显示面板的平面示意图。如图5所示,副隔垫物132包括第一副隔垫物1321和第二副隔垫物1322,第一副隔垫物1321在第二基板120上的正投影沿偏移方向与对应设置的第二凸台142在第二基板120上的正投影距离第一距离S1设置,第二副隔垫物1322在第二基板120上的正投影沿偏移方向与对应设置的第二凸台142在第二基板120上的正投影距离第二距离S2设置,第二距离S2小于第一距离S1。由此,当该显示面板的第一基板110和第二基板120沿与上述的偏移方向相反的反方向发生相对位移时,例如,相对位移为第一距离S1时,第一副隔垫物1321在第二基板120上的正投影与对应设置的第二凸台142在第二基板120上的正投影重 叠,即第一副隔垫物1321移动到对应设置的第二凸台142上;此时,即使主隔垫物131因第一基板110和第二基板120的相对位移而从第一凸台141滑落,第一副隔垫物1321可移动第二凸台142并对第一基板110和第二基板120起到支撑作用,从而可避免主隔垫物131划伤取向膜129。当该显示面板的第一基板110和第二基板120沿与上述的偏移方向相反的反方向发生相对位移时,例如,相对位移为第二距离S2时,第二副隔垫物1322在第二基板120上的正投影与对应设置的第二凸台142在第二基板120上的正投影重叠,即第二副隔垫物1322移动到对应设置的第二凸台142上;此时,即使主隔垫物131因第一基板110和第二基板120的相对位移而从第一凸台141滑落,第二副隔垫物1322可移动第二凸台142并对第一基板110和第二基板120起到支撑作用,从而可避免主隔垫物131划伤取向膜129。需要说明的是,本公开包括但不限于此,副隔垫物还可包括除了第一副隔垫物和第二副隔垫物之外的,沿偏移方向偏移其他距离的副隔垫物,从而保证当该显示面板的第一基板110和第二基板120沿与上述的偏移方向相反的反方向发生相对位移时,副隔垫物中的至少一个可以移动到对应设置的第二凸台上,从而避免主隔垫物131划伤取向膜129。
例如,在一些示例中,第二距离S2可设置为第一距离S1的四分之一到四分之三,从而合理地排列第一副隔垫物和第二副隔垫物,提高对副隔垫物的利用效率。
例如,第二距离S2可设置为第一距离S1的二分之一,从而合理地排列第一副隔垫物和第二副隔垫物,提高对副隔垫物的利用效率。
需要说明的是,上述的“第一距离”可为第一副隔垫物在第二基板上的正投影与对应设置的第二凸台在第二基板上的正投影的相邻的两边缘的距离;同样地,上述的“第二距离”可为第二副隔垫物在第二基板上的正投影与对应设置的第二凸台在第二基板上的正投影的相邻的两边缘的距离。例如,在一些示例中,如图5所示,多个副隔垫物132在第二基板120上的正投影沿不同的偏移方向与第二凸台142在第二基板120上的正投影距离预设距离设置。也就是说,多个副隔垫物132沿不同的方向偏离对应设置的第二凸台142。由此,当该显示面板的第一基板110和第二基板120沿不同的方向发生相对位移时,总有副隔垫物在第二基板上的正投影与对应设置的第二凸台在第二基板上的正投影重叠,即总有副隔垫物移动到对应设置的第二凸台上;此时,即使主隔垫物因第一基板和第二基板的相对位移而从第一凸台滑落,部分副隔垫物可移动 第二凸台并对第一基板和第二基板起到支撑作用,从而可避免主隔垫物划伤取向膜。
例如,在一些示例中,如图5所示,上述的不同的偏移方向可包括第一方向、第二方向、第三方向和第四方向,第一方向和第四方向相反,第二方向与第三方向相反,第一方向垂直于第二方向。
例如,在一些示例中,如图5所示,上述的不同的偏移方向还可包括第五方向、第六方向、第七方向和第八方向,第五方向和第八方向相反,第六方向与第七方向相反,第五方向与第一方向的夹角范围在30-60度,第六方向与第二方向的夹角范围在30-60度。由此,该显示面板可进一步保证当该显示面板的第一基板和第二基板沿不同的方向发生相对位移时,总有副隔垫物可移动到对应设置的第二凸台上。
例如,在一些示例中,如图5所示,上述第五方向和第一方向的夹角为45度,第六方向与第二方向的夹角为45度。由此,第一方向、第二方向、第三方向、第四方向、第五方向、第六方向、第七方向以及第八方向在平面内均匀分布。
例如,在一些示例中,如图5所示,第二基板120还包括栅线121;主隔垫物131呈阵列设置,用于维持第一基板110和第二基板120之间的距离,也就是说,主隔垫物131均匀地设置在第一基板110和第二基板120之间;同属同一行的主隔垫物131沿栅线121的延伸方向呈线状排列。
例如,在一些示例中,如图5所示,栅线121在第二基板120上的正投影与主隔垫物131在第二基板120上的正投影至少部分重叠。
例如,在一些示例中,如图5所示,上述的不同的偏移方向的第一方向可为垂直于栅线121的延伸方向的方向。
例如,在一些示例中,如图5所示,第二凸台142呈阵列设置在第二基板120上,同属同一行的第二凸台142沿栅线121的延伸方向呈线状排列。
例如,在一些示例中,如图5所示,同属一行的第二凸台142和主隔垫物131沿栅线121的延伸方向呈线状排列,也就是说,相对于常规设计,第二凸台不作偏移,只通过将副隔垫物132进行偏移来实现副隔垫物132在第二基板120上的正投影沿偏移方向与对应设置的第二凸台142在第二基板120上的正投影距离预设距离设置。
例如,在一些示例中,如图5所示,该显示面板还包括:黑矩阵150,设 置在第一基板110或第二基板120上,主隔垫物131在第二基板上的正投影落入黑矩阵150在第二基板120上的正投影。也就是说,主隔垫物131设置在黑矩阵150的覆盖范围之内。当然,第一凸台141和第二凸台142也可设置在黑矩阵150的覆盖范围之内。由此,可降低主隔垫物、第一凸台和第二凸台对该显示面板的开口率的影响。
例如,在一些示例中,如图5所示,黑矩阵的边缘与主隔垫物的边缘的最短距离L小于15微米。在本公开实施例提供的显示面板中,黑矩阵可设置地较窄,从而可提高该显示面板的开口率。
值得注意的是,由于副隔垫物在第二基板上的正投影沿偏移方向与对应设置的第二凸台在第二基板上的正投影距离预设距离设置,副隔垫物在第二基板上的正投影可不落入黑矩阵在第二基板上的正投影,从而可避免因增加黑矩阵宽度而导致的降低显示面板开口率的问题。当然,本公开实施例包括但不限于此,副隔垫物在第二基板上的正投影也可落入黑矩阵在第二基板上的正投影。
例如,在一些示例中,如图5所示,同属同一行的副隔垫物132具有所有的偏移方向。当然,本公开包括但不限于此,也可两行副隔垫物132具有所有的偏移方向。
图6为根据本公开一实施例提供的另一种显示面板的平面示意图。如图6所示,在该显示面板中,副隔垫物132和主隔垫物131呈阵列设置,同属同一行的副隔垫物132和主隔垫物131沿栅线的延伸方向呈线状排列。也就是说,相对于常规设计,副隔垫物132不作偏移,只通过将第二凸台142进行偏移来实现副隔垫物132在第二基板120上的正投影沿偏移方向与对应设置的第二凸台142在第二基板120上的正投影距离预设距离设置。
例如,在一些示例中,如图6所示,类似地,主隔垫物131和副隔垫物132在第二基板上的正投影落入黑矩阵150在第二基板120上的正投影。由此,可降低主隔垫物、副隔垫物对该显示面板的开口率的影响。此时,由于副隔垫物在第二基板上的正投影沿偏移方向与对应设置的第二凸台在第二基板上的正投影距离预设距离设置,第二凸台在第二基板上的正投影可不落入黑矩阵在第二基板上的正投影,从而可避免因增加黑矩阵宽度而导致的降低显示面板开口率的问题。当然,本公开实施例包括但不限于此,第二凸台在第二基板上的正投影也可落入黑矩阵在第二基板上的正投影。
值得注意的是,本公开中的不同的偏移方向不仅包括上述的四个方向和八 个方向的情况,具体的偏移方向可根据实际情况进行设置。例如,不同的偏移方向可只包括三个偏移方向。图7A为根据本公开一实施例提供的一种显示面板的平面示意图。如图7A所示,多个偏移方向包括第一方向、第九方向和第十方向。例如,如图7A所示,第一方向、第九方向和第十方向可均匀分布,即第一方向与第九方向之间的夹角为120度,第九方向和第十方向之间的夹角为120度。
例如,在一些示例中,如图7A所示,该显示面板包括多个子像素单元300。各子像素单元300对应设置一个主隔垫物131或一个副隔垫物132。然而,本公开包括但不限于此,也可在一个子像素单元中设置一个主隔垫物或多个副隔垫物。例如,图7B示出了根据本公开一实施例提供的一种显示面板中两个像素单元的示意图,如图7B所示,在各子像素单元300中,可设置三个副隔垫物1321或1322。当然,本公开实施例提供的显示面板还可在一个子像素单元中设置更多的副隔垫物,例如,四个副隔垫物或八个副隔垫物。
图8为根据本公开一实施例提供的一种显示面板的平面示意图。如图8所示,在该显示面板中,相对于常规设计,副隔垫物132和第二凸台142均作偏移,以实现副隔垫物132在第二基板120上的正投影沿偏移方向与对应设置的第二凸台142在第二基板120上的正投影距离预设距离设置。例如,如图8虚线框中的副隔垫物132和第二凸台142所示,该副隔垫物132沿第二方向移动20单位距离,第二凸台142沿与第二方向相反的第四方向移动20单位距离,由此,相对于第二凸台142,副隔垫物132在第二基板120上的正投影沿第二方向与对应设置的第二凸台142在第二基板120上的正投影距离40单位距离设置。此时,如图8所示,副隔垫物132和第二凸台142设置在黑矩阵150的边缘部分,并非位于黑矩阵150的中心区域。由此,该显示面板可通过同时将副隔垫物和第二凸台均作偏移,在达到相同的预设距离的前提下,副隔垫物和第二凸台分别相对于第二基板的移动距离较小,可尽可能地设置在黑矩阵的覆盖范围内,从而可进一步减小副隔垫物和第二凸台对该显示面板的开口率的影响。
本公开至少一个实施例还提供一种显示装置。图9为根据本公开一实施例提供的一种显示装置的结构示意图。如图9所示,该显示装置包括根据上述任一实施例所提供的显示面板100。由此,该显示装置也同样具有与其包括的显示面板的有益效果对应的技术效果,具体可参见上述描述。
例如,在一些示例中,该显示装置可以为智能手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
例如,在一些示例中,该显示装置还包括背光模组500,设置在显示面板100的一侧并可为显示面板100提供背光。需要说明的是,该显示装置还可包括用于实现其他功能的部件和设备,本公开实施例在此不作限制。
例如,在一些示例中,该显示装置可以为智能手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
有以下几点需要说明:
(1)本公开实施例附图中,只涉及到与本公开实施例涉及到的结构,其他结构可参考通常设计。
(2)在不冲突的情况下,本公开同一实施例及不同实施例中的特征可以相互组合。
以上,仅为本公开的具体实施方式,但本公开的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本公开揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本公开的保护范围之内。因此,本公开的保护范围应以权利要求的保护范围为准。
