请参考图2,图2为本发明实施例提供的电子终端的示意图。图2示出了电子终端为手机的示例,其中,电子终端400包括显示面板200和摄像组件300,摄像组件300设置于第二显示区A2,第二显示区A2包括多个显示子区A21,显示子区A21包围摄像组件300的至少一部分。摄像组件300用于获取透过第二显示区A2的外界光信号。也可以理解为,摄像组件300设置在显示面板200第二显示区A2下方,摄像组件300用于获取透过显示面板200的第二显示区A2的外界光信号,并根据获取的外界光信号成像。本发明实施例提供的电子终端400的显示面板200的显示区域完整,提高了电子终端的屏占比。其中,摄像组件300可以作为电子终端的前置摄像组件,摄像组件300可以用于透过显示面板200的第二显示区A2获取用户的自拍照等图像。
当摄像组件300开启时,与第二显示区A2对应的透光部处于完全透明状态,摄像组件300获取透过透光部的外界光信号进行成像。当显示面板200用于显示时,第一显示区A1以及与第二显示区A2对应的显示部显示图像,与第二显示区A2对应的透光部处于不透明状态,呈现灰阶或黑态,提高电子终端的屏占比,实现全面屏显示效果。
本发明实施例还提供一种显示面板。请结合图3和图4,其中,图3为本发明实施例中显示面板的俯视图,图4为显示面板沿B-B'部分截取的剖面图。显示面板200包括第一显示区A1和第二显示区A2,第一显示区A1围绕第二显示区A2的至少一部分。其中,第二显示区A2包括多个显示子区A21,显示子区A21包括显示部A21a和透光部A21b。
具体的,显示子区A21设置有开关控制单元、透明电极组合20、液晶层30和彩膜层40。透明电极组合20与开关控制单元电性连接,其中,开关控制单元包括第一开关控制单元10a和第二开关控制单元10b。透明电极组合20对应显示部A21a和透光部A21b设置,透明电极组合20用于控制液晶层30中液晶分子的偏转方向,使得透光部A21b处于透光状态或不透光状态。液晶层30设置于显示部A21a和透光部A21b。彩膜层40设置于显示部A21a。
第一开关控制单元10a用于独立控制透光部A21b中透明电极组合20的电压,使得透光部A21b独立进行灰阶显示,与已知技术中透光部只显示黑态的设置方式相比,提高了显示面板的屏占比。在一实施例中,第一开关控制单元10a仅为一个薄膜晶体管,用于单独控制透光部A21b处于透光状态或不透光状态。
透明电极组合20包括第一像素电极201a、第二像素电极201b和公共电极202,其中,第一像素电极201a、第二像素电极201b和公共电极202设置在液晶层30的一侧。或者,第一像素电极201a、第二像素电极201b和公共电极202分别设置在液晶层30的两侧。需要说明的是,本实施例以第一像素电极201a、第二像素电极201b和公共电极202设置在液晶层30的一侧为例,即该显示面板200为平面转换(In-PlaneSwitching,IPS)模式显示面板。应该理解的是,本发明实施例还包括其他模式的显示面板,例如,包括扭曲向列(TwistedNematic,TN)、垂直配向(Vertical Alignment,VA)型以及边缘场开关(Fringe Field Switching,FFS)型。像素电极201和公共电极202包括透明ITO(氧化铟锡)电极。
进一步的,请参考图5,图5为显示面板200在显示子区A21的俯视图。显示子区还设置有扫描线101和数据线102。其中,扫描线101沿第一方向D1延伸,扫描线101包括相互连接的第一段101a和第二段101b。其中,扫描线101的第一段101a设置在显示部A21a,扫描线101的第二段101b设置在透光部A21b,扫描线101的第二段101b为透明扫描线。数据线102沿第二方向D2延伸,数据线102包括第一段102a和第二段102b,数据线102的第一段102a设置在显示部A21a,数据线102的第二段102b设置在透光部A21b,数据线102的第二段102b为透明数据线。并且,两条相邻的扫描线101的第一段101a和数据线102的第一段102a交叉界定为像素单元,像素单元用于显示彩色。其中,像素单元包括红色子像素单元R、绿色子像素单元G和蓝色子像素单元B。
进一步的,请继续参考图5,数据线102包括第一类数据线1021和第二类数据线1022,第一类数据线1021和第二类数据线1022沿第一方向D1排列,其中,第二类数据线1022的第一段1022a包括透明数据线,第一类数据线1021的第二段1021b为透明数据线。第二类数据线1022设置在显示部A21a靠近透光部A21b的一侧。并且,靠近透光部A21b的第二类数据线1022的第一段1022a与第一开关控制单元10a电性连接。
请结合图4和图6,透明电极组合20包括第一像素电极201a、第二像素电极201b,第一像素电极201a设置于与所述透光部对应的部分。开关控制单元包括第一开关控制单元10a和第二开关控制单元10b,第一开关控制单元10a设置于与透光部A21b对应的部分,第二开关控制单元10b设置于与显示部A21a对应的部分。第一开关控制单元10a与第一像素电极201a电性连接,并且,第一开关控制单元10a与第二类数据线1022连接,第一开关控制单元10a用于控制第一像素电极201a的施加电压,从而独立控制透光部A21b,使得透光部A21b处于透光状态或不透光状态。
第二开关控制单元10b与第二像素电极201a电性连接,且第二开关控制单元10b与第一类数据线1021电性连接,第二控制单元10b用于控制第二像素电极201b的施加电压,使得显示部A21a处于显示状态或非显示状态。
当所述透光部A21b处于透光状态时,所述显示部A21a处于非显示状态;当所述透光部A21b处于非透光状态时,所述显示部A21a处于显示状态或非显示状态。
需要说明的是,透光部A21b设置有第一像素电极201a和公共电极202,其中,第一像素电极201a和公共电极202设置在液晶层30的一侧。或者,第一像素电极201a和公共电极202分别设置在液晶层30的两侧。当向第一像素电极201a施加高电压时,第一像素电极201a和公共电极202为高夹压,控制透光部A21b中液晶层30中液晶分子的偏转,此时,液晶层30为透明状态。当向第一像素电极201a施加低电压时,第一像素电极201a和公共电极202为低夹压,控制透光部A21b中液晶层30中液晶分子的偏转,此时,液晶层30为不透明状态,呈现灰阶或黑态。在本发明实施例中,与第二显示区A2对应设置的显示部A21a具有显示功能,而透光部A21b具有透光功能,可以对第二显示区A2进行补光,降低了对背光模组的光的依赖。
请结合图5和图7,图7为显示子区A21设置彩膜层40的俯视图。彩膜层40包括遮光条402和色阻块401,遮光条402与第一类数据线1021的第一段1021a对应设置,靠近透光部A21b一侧的色阻块401与透光部A21b连接。色阻块401包括第一色阻块401a、第二色阻块401b和第三色阻块401c。
请结合图4、图5和图8,图8为本发明实施例中第一基板的结构示意图。扫描线101的第二段101b与数据线102的第二段102b同层设置。具体的,显示面板200还包括相对设置的第一基板B1和第二基板B2。液晶层30设置在第一基板B1和第二基板B2之间。具体的,第一基板B1包括衬底103、遮光层104、有源层105、栅极绝缘层106、栅极107、层间介质层108、源极109和漏极110以及平坦化层111。遮光层104设置在衬底103上,其中,衬底103包括玻璃基板、缓冲层和阻挡层等结构。有源层105设置在衬底103上,且有源层105与遮光层104对应设置,并且,遮光层104在衬底103上的正投影完全覆盖有源层105在衬底103上的正投影。栅极绝缘层106覆盖有源层105和衬底103。栅极107设置在栅极绝缘层106上,并且,有源层105在衬底103上的正投影完全覆盖栅极107在衬底103上的正投影。层间介质层108覆盖栅极107和栅极绝缘层106。源极109和漏极110分别与有源层105电性连接。平坦化层111覆盖层间绝缘层106。其中,扫描线101的第二段101b通过第一基板B1的层间介质层108的过孔与第一基板B1的栅极107搭接形成。并且,数据线102的第二段102b通过层间介质层108的过孔与第一基板B1的源极109搭接形成。
扫描线101的第一段101a的材质与栅极的材质相同,包括金属铜、铝、镍、钼等金属中的一种或其组合形成的合金材料。扫描线101的第二段101b的材质包括透明的ITO材料。
第一类数据线1021的第一段1021a的材料与源极109和漏极110的材质相同,包括金属铜、铝、镍、钼等金属中的一种或其组合形成的合金材料。第一类数据线1021的第二段1021b和第二类数据线1022的材质包括透明的ITO材质。
本发明实施例将扫描线101的第二段101b、第一类数据线1021的第二段1021b和第二类数据线1022设计为透明材料,并且,通过过孔将扫描线101的第二段101b与数据线102同层设置,使得位于透光部A21b的数据线102的第二段102b和扫描线101的第二段均为透明的,增大了透光部A21b的光的透光率。
第二基板B2包括玻璃基板。需要说明的是,本发明实施例中的彩膜层40可以设置在第二基板B2上,即显示面板为Non-COA架构的显示面板。或者,彩膜层40也可以设置在第一基板B1上,即显示面板为阵列基板上彩色滤光片(Color Filter On Array,COA)架构的显示面板。
请结合图4和图8,与第一显示区A1对应设置的数据线102和扫描线101分别与源极109和栅极107同层设置,并且,与第一显示区A1对应设置的数据线102和扫描线101的材料包括铝、铜、镍、钼等金属材料中的一种或由不同金属组成的合金材料。也就是说,与第一显示区A1对应设置的数据线102和扫描线101并不是同层设置的。而与第二显示区A2对应的扫描线101的第二段101b和数据线102是同层设置的,并且,扫描线101的第二段101b和数据线102的第二段102b的材质均为透明材质,增大了透光部A21b的光的透过率。进一步的,如图4所示,与第二显示区A2对应的透光部A21b的第一像素电极201a与第一开关控制单元10a电性连接,第一开关控制单元10a可独立控制透光部A21b的液晶层30中液晶分子的偏转,使其具备灰阶显示功能。并且,透光部A21b不设置彩膜层40,使其具备透光的功能。而与第二显示区A2对应的显示部A21a设置有彩膜层40,彩膜层40与设置于显示部A21a的像素单元用于共同显示图像。使得第二显示区A2对应设置的显示部A21a可以显示图像,与已知技术中的第二显示区只能显示黑态相比,增大了显示面板的屏占比。并且,靠近透光部A21b的色阻块401与透光部A21b相连,减小了遮光条402对透光部A21b的透光效果的影响。
进一步的,第一显示区A1的像素单元的分布密度大于第二显示区A2的像素单元的分布密度。可选的,第一显示区A1的像素单元的分布密度为第二显示区A2的像素单元的分布密度的4倍。
如图2所示,本发明实施例针对第二显示区A2设计一种像素结构,使得第二显示区A2既能进行显示,又能满足摄像组件300成像的需求。
如图1所示,在已知技术中,开孔区N用于放置摄像组件,该区域只能进行摄像拍照,而无法用于显示。即,当显示区进行显示时,开孔区N是一个黑色的圆,给人肉眼比较突兀的感觉。如图2所示,本发明实施例提供的电子终端的摄像组件300开启时,与第二显示区A2对应的透光部处于完全透明状态,摄像组件300获取透过透光部的外界光信号进行成像。当显示面板200用于显示时,第一显示区A1以及与第二显示区A2对应的显示部显示图像,与第二显示区A2对应的透光部处于不透明状态,呈现灰阶或黑态,提高电子终端的屏占比,实现全面屏显示效果。本发明实施例提供的电子终端保证显示效果的同时,提高与第二显示区对应的透光部的透光率,使两者能够平衡,满足客户的需求。
如图8所示,本发明实施例在第一基板B1制作有源层105的制程后增加一道黄光制程,形成与源极109电性连接的氧化铟锡,其中,氧化铟锡可以设置在源漏极的上方或者下方。其主要作用是与源漏极或栅极相连,在需要透光的区域将源漏极或栅极金属换层透明的ITO。
本发明实施例的第二显示区A2的像素设计为将此区域显示的像素密度降低,以第一显示区A1的像素密度为395PPI(Pixels Per Inch,像素密度)为例,第二显示区A2的像素密度降低3倍至131PPI或降低2倍至197PPI。
具体的,请参考图5,图5为第二显示区中一显示子区A21,其中,右上角为显示部A21a,其他区域为透光部A21b。其中,透光部A21b为完全透光,其具体实施方式为将透光部金属换层设置,水平方向栅极显示部为栅极,在进入透光部处通过层间介质层换层源漏极,源漏极再直接换层扫描线的第二段,实现栅极在透光部换层透明的氧化铟锡。竖直方向数据线在透光部直接换层为透明氧化铟锡。
请结合图5和图7,第二色阻块401b和第一色阻块401a或者第二色阻块401b和第三色阻块401c之间仍采用遮光条402遮挡,防止大视角色偏,第一色阻块401a或第三色阻块401c与透光部A21b未设置遮光条。
具体的,第二类数据线1022设置为氧化铟锡透明层,与第二类数据线1022对应的遮光条取消。而绿色子像素单元左右两边数据线仍维持源漏极的金属设置,与绿色子像素单元左右两边数据线对应的彩膜层仍采用遮光条遮挡。蓝色子像素单元左边用于控制透光部A21b的数据线设置为氧化铟锡透明层。
请继续参考图5,每个显示子区A21里设置1条透明数据线,增加开关控制单元控制透光部的透明电极组合,使每个显示子区的透光部能独立显示灰阶。该设置方式使得透光部没有不透光的金属存在,使得对应131PPI透光部占比86.5%,对应197PPI透光部占比70%。需要说明的是,本发明实施例只是将第二显示区的像素密度为131PPI和197PPI两个实例举例,其他实施例也在本专利的保护范围。
请结合图2和图6,在本发明实施例中,当摄像组件300工作时,透光部A21b要完全透明,让摄像组件300采集外来的影像;当摄像组件300不工作时,与第二显示子区A21对应的显示部要求显示,此时,透光部A21b要变成灰阶或黑色,不能影响正常显示。
请参考图4,透光部A21b设置有像素电极201和公共电极202。当像素电极201给高电压时,像素电极201和公共电极202为高夹压,控制液晶偏转,液晶层为透明态。
当像素电极201给低电压时,像素电极201和公共电极202为低夹压,控制液晶偏转,液晶层为不透光状态,呈现灰阶或黑态。
本发明实施例在第二显示区A2的显示子区A21加入独立的开关控制单元。相当于每个显示子区里的透光部独立控制,进行独立的灰阶显示,而不是只显示黑态。其主要目的是第二显示区相比正常区域,以第二显示区的像素密度为200PPI为例,像素单环显示密度只有1/4。若使肉眼观察没有明显的突兀显示效果,第二显示区的亮度需要提高至好几倍,因此,背光模组的亮度需要独立特殊设计。而本发明实施例在显示时段,独立的透光部从标准的黑态调整为灰阶显示,进行补光设计,降低对背光模组的依赖。
另外,由于第二显示区A2的像素单元的显示密度较低,色点漂移严重,本发明实施例独立的透光部灰阶显示对改善色点漂移有较大帮助。
本发明实施例提供一种显示面板和电子终端,本发明实施例提供的显示面板包括第一显示区和第二显示区。本发明实施例的显示面板在第二显示区设置显示部和透光部,其中,显示部具备显示功能,而透光部具有独立控制的开关控制单元,可以独立控制透光部的对应的液晶层中液晶分子的偏转,实现透光功能,使得第二显示区同时具备显示功能和透光功能,提高显示面板的屏占比,实现真正意义上的全面屏显示。
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。
