Description

显示面板及显示装置
技术领域
本发明涉及显示技术领域,尤其涉及一种显示面板及具有该显示面板的显示装置。
背景技术
随着显示面板技术越来越成熟,液晶显示面板由于其具有重量轻、体积小和厚度薄等特点,已广泛地被用在各种大中小尺寸的显示设备中。目前,市场上对应液晶显示产品的性能要求朝着高对比度和宽视野角度等特性发展。目前能够实现宽视野角度要求的技术主要有三种方式:扭转向列型液晶显示设备、共平面切换型液晶显示设备和多畴垂直配向模式液晶显示设备。其中,多畴垂直配向模式液晶显示设备由于在量产性和显示特性等方面的优越性,成为市场上主流的液晶显示设备之一。
传统的垂直配向模式液晶显示面板由于液晶分子双折射率差异较大,进而导致大视角色偏严重。而现有技术中,通过将传统的4畴子像素分为main/sub(主/次)区,以形成8畴子像素,使得同一个子像素内主区的4个畴与次区的4个畴的液晶分子转动角度不同,可以有效改善色偏。
目前,实现8畴子像素的主流方法有3T技术(即包括main TFT、sub TFT以及shareTFT,其中,main TFT和sub TFT的尺寸相同,分别给main/sub区充电,同时,share TFT给sub区漏电,使main/sub区电压具有一定差异,以使得main/sub区对应的液晶分子具有不同的液晶偏转角度),请参照图1,为现有的显示面板中LCS-灰阶曲线示意图,其中,LCS为sub区的像素电压与main区的像素电压的比值,测得在低灰阶(0灰阶)时,LCS值为接近0.8;在高灰阶(255灰阶)时,LCS值接近0.75,进而使得子像素在低灰阶时LCS高,使得main/sub区对应的液晶分子的偏转角度差异小,使得低灰阶时显示面板的视角范围受限,而视角范围受限将不利于显示,而子像素在高灰阶时LCS低,使得main/sub区对应的液晶分子的偏转角度差异大,但是将会使得穿透率降低,同样不利于显示,因此,现有技术难以使得显示面板分别在低灰阶和高灰阶时的穿透率和视角达到均衡。
发明内容
本发明实施例提供一种显示面板及显示装置,能够解决现有技术中无法均衡穿透率和视角的技术问题。
为解决上述技术问题,本发明实施例提供一种显示面板,其包括:
多个数据信号线,多个所述数据信号线用于提供像素电压;
多个共享信号线,多个所述共享信号线用于提供共享电压信号;以及
多个子像素,每个所述子像素包括第一像素电极以及第二像素电极;
其中,所述第一像素电极与所述数据信号线电连接以具有第一像素电压,所述第二像素电极与所述数据信号线以及所述共享信号线电连接以具有第二像素电压,当所述子像素处于低灰阶状态时,所述第二像素电压与所述第一像素电压具有第一比值;当所述子像素处于高灰阶状态时,所述第二像素电压与所述第一像素电压具有第二比值,所述第二比值大于所述第一比值。
在本发明的一种实施例中,当所述像素电压为正极性时,所述共享电压信号为第一电压,当所述像素电压为负极性时,所述共享电压信号为第二电压,所述第一电压与所述第二电压不同。
在本发明的一种实施例中,所述第一电压小于所述第二电压。
在本发明的一种实施例中,所述第一电压为4V,所述第二电压为12V。
在本发明的一种实施例中,当所述子像素的灰阶大于70灰阶时,所述第二像素电压与所述第一像素电压的比值随所述子像素的灰阶的提高而增大。
在本发明的一种实施例中,所述显示面板还包括公共电极层,所述公共电极层具有第一公共电压,当所述像素电压为正极性时,所述第二像素电压与所述第一公共电压的差值的绝对值为第三值,当所述像素电压为负极性时,所述第二像素电压与所述第一公共电压的差值的绝对值为第四值,且所述第三值等于所述第四值。
在本发明的一种实施例中,所述第一公共电压包括直流电信号。
在本发明的一种实施例中,所述显示面板包括相对设置的阵列基板、彩膜基板以及设置于所述阵列基板与所述彩膜基板之间的液晶层;其中,所述阵列基板包括像素电极层,所述像素电极层包括位于同层的所述第一像素电极和所述第二像素电极,所述彩膜基板包括所述公共电极层,且所述像素电极层与所述公共电极层相对设置。
在本发明的一种实施例中,所述第一像素电极以及所述第二像素电极各自沿所述共享信号线呈轴对称分布。
根据本发明的上述目的,提供一种显示装置,所述显示装置包括背光源以及所述显示面板,所述背光源连接于所述显示面板,并用于为所述显示面板提供背光。
本发明的有益效果:在本发明中,当子像素处于低灰阶状态时,第二像素电压与第一像素电压具有第一比值;当子像素处于高灰阶状态时,第二像素电压与第一像素电压具有第二比值,第二比值大于第一比值,进而使得显示面板在低灰阶时LCS低,即在低灰阶显示时,使得第一像素电极以及第二像素电极所对应的液晶分子的偏转角度差异大,使得显示面板获得较大范围的视角,而在高灰阶时LCS高,即在高灰阶显示时,使得第一像素电极以及第二像素电极所对应的液晶分子的偏转角度差异较小,使得子像素的穿透率趋于均一,进而获得更大的穿透率,提高了显示面板的显示效果。

本发明实施例提供一种显示面板及显示装置,针对现有的垂直配向模式液晶显示面板,请参照图1,为现有的显示面板中LCS-灰阶曲线示意图,其中,LCS为sub区的像素电压与main区的像素电压的比值),测得在低灰阶(0灰阶)时,LCS值为接近0.8;在高灰阶(255灰阶)时,LCS值接近0.75,进而使得子像素在低灰阶时LCS高,使得main/sub区对应的液晶分子的偏转角度差异小,使得低灰阶时所述显示面板的视角范围受限,而子像素在高灰阶时LCS低,使得main/sub区对应的液晶分子的偏转角度差异大,但是将会使得穿透率降低,同样不利于显示,因此,现有技术难以满足显示面板在低灰阶时具有较好的视角以及在高灰阶时具有较高的穿透率的要求。
为解决上述技术问题,本发明实施例提供一种显示面板,请参照图2,所述显示面板包括多个数据信号线30、多个共享信号线40以及多个子像素,且图2中仅示出其中一个子像素的结构示意图为例以作说明,其中,多个所述数据信号线30用于提供像素电压Vs,多个所述共享信号线40用于提供共享电压信号Vg,每个所述子像素包括第一像素电极12以及第二像素电极23。

进一步地,所述显示面板还包括驱动模组,所述共享信号线40与所述驱动模组电性连接,以向所述共享薄膜晶体管22传输所述共享电压信号Vg。
其中,所述第一像素电极12等分成四个区域,且沿所述共享信号线40呈轴对称分布,所述第一像素电极12包括位于所述共享信号线40两侧的各两个区域,所述第二像素电极23等分成四个区域,且沿所述共享信号线40呈轴对称分布,所述第二像素电极23包括位于所述共享信号线40两侧的各两个区域,以形成本发明实施例提供的八畴像素结构。
需要说明的是,所述第一薄膜晶体管11与所述第二薄膜晶体管21的尺寸相同,以分别向所述第一子像素10以及所述第二子像素20传输所述像素电压Vs,以使所述第一像素电极12具有第一像素电压,同时,为了实现视角范围的扩大,改善色偏现象,所述共享薄膜晶体管22根据所述共享电压信号Vg对所述第二薄膜晶体管21进行放电,进而对所述第二子像素20进行漏电,以使得所述第二子像素电极23具有第二像素电压,进而使得所述第一像素电压与所述第二像素电压具有差异,使得所述第一子像素10所对应的液晶分子的偏转角度与所述第二子像素20所对应的液晶分子的偏转角度具有差异,进而可以扩大视角范围。
在本发明实施例中,当所述像素电压Vs为正极性时,即电性为正,所述共享电压信号Vg为第一电压,当所述像素电压Vs为负极性时,即电性为负,所述共享电压信号Vg为第二电压,且所述第一电压与所述第二电压不同,以使得所述第二比值大于所述第一比值,可向所述共享信号线40内通入交流方波信号。
请参照图5,其中曲线B为对所述共享信号线40采用现有的供电方式得出了LCS与灰阶的关系曲线,具体地,对所述共享信号线40通入直流电信号,取所述共享电压信号Vg恒为9V,经模拟得到曲线B,其中,所述子像素在低灰阶时LCS高,且LCS为80%左右,所述子像素在高灰阶时LCS低,且LCS值为76%左右,进而无法满足LCS在低灰阶时低(具有较好的视角)以及在高灰阶时高(具有较高的穿透率)的要求。
在本发明实施例中,所述第一电压与所述第二电压不同,具体地,所述第一电压小于所述第二电压,请参照图5以及图6,取所述第一电压为4V,所述第二电压为12V,经模拟得到曲线A,其中,所述子像素在低灰阶时LCS低,且LCS值为70%左右,所述子像素在高灰阶时LCS高,且LCS值为77%左右,进而可以满足LCS在低灰阶时低(具有较好的视角)以及在高灰阶时高(具有较高的穿透率)的要求,进一步地,当所述子像素的灰阶大于70灰阶时,所述第二像素电压与所述第一像素电压的比值(即LCS)随所述子像素的灰阶的提高而增大。
另外,所述公共电极层53具有所述第一公共电压,且所述第一公共电压为直流电信号,为恒定值,而现有技术中对所述共享信号线40采用直流电的供电方式,则当所述像素电压Vs分别为正极性和负极性时,皆通过一恒定的共享电压信号Vg对所述第二薄膜晶体管21进行放电,形式单一,将使得所述第二像素电压与所述第一公共电压的差值的绝对值分别在所述像素电压Vs为正极性和负极性时相差较大,进而将影响所述第二像素电压在所述像素电压Vs分别为正负极性时的对称性,降低了显示效果。
而本发明实施例中,所述第一电压与所述第二电压不同,通过选择合适的所述第一电压以及所述第二电压,可使得当所述像素电压Vs为正极性时,所述第二像素电压与所述第一公共电压的差值的绝对值为第三值,当所述像素电压Vs为负极性时,所述第二像素电压与所述第一公共电压的差值的绝对值为第四值,且所述第三值等于所述第四值,即使得所述第二像素电压在所述像素电压Vs分别为正极性和负极性时具有对称性,以提高所述显示面板的显示均一性,进而提高了显示效果,进一步地,所述第一电压以及所述第二电压的数值,即所述共享电压信号Vg可根据所述像素电压Vs与第二薄膜晶体管21的I-V曲线,进行模拟得到,在此不作限定。
因此,本发明实施例可以实现所述显示面板在低灰阶显示时,使得所述第一子像素10以及所述第二子像素20所对应的液晶分子的偏转角度差异较大,使得所述显示面板具有较大的视角范围,而在高灰阶显示时,使得所述第一子像素10以及所述第二子像素20所对应的液晶分子的偏转角度差异较小,使得所述第二子像素20的穿透率与所述第一子像素10的穿透率大致相同,进而获得更大的穿透率,提高了所述显示面板的显示效果,且本发明实施例中可通过选择合适的共享电压信号Vg,以保证所述第二像素电压在所述像素电压Vs分别为正极性和负极性时的对称性。
另外,本发明实施例还提供一种显示装置,且所述显示装置包括上述实施例中所述的显示面板以及连接于所述显示面板至少一侧的背光源,以用于为所述显示面板提供背光。
综上所述,本发明实施例提供一种显示面板及具有该显示面板的显示装置,通过在所述像素电压Vs分别在正极性和负极性时,向所述共享信号线40通入不同的电压信号,进而使得在所述显示面板显示低灰阶时具有低的LCS,以扩大显示面板的视角范围,在所述显示面板显示高灰阶时具有高的LCS,以提高所述显示面板的穿透率,并可以保持所述第二像素电压在所述像素电压Vs为正负极性时的对称性。
