Description

液晶显示面板、液晶显示面板制备方法及显示装置
本发明要求2018年2月5日递交的发明名称为“液晶显示面板、液晶显示面板制备方法及显示装置”的申请号201810112261.0的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及显示技术领域，尤其涉及一种液晶显示面板、液晶显示面板制备方法及显示装置。
背景技术
液晶显示面板(Liquid Crystal Display，LCD)具有机身薄、功耗低、辐射小以及画面显示柔和等等优点，具有广泛的应用。穿透率(transmittance ratio)是液晶显示面板显示品质的一个重要指标，提高液晶显示器的穿透率，可以降低背光能耗，降低成本。在相同背光的情况下，可以实现更大的亮度，灰阶层次可以调整的更分明。通常影响液晶显示面板穿透率的几大块要素包括：偏光片，液晶效率，阵列基板和彩膜基板的膜层吸收以及液晶显示面板的开口率。液晶效率是指液晶显示面板相同开口率下的穿透率。而液晶效率的好坏与像素电极的设计息息相关，不同的像素电极设计，直接影响着液晶显示面板的穿透率。
发明内容
本发明提供一种液晶显示面板，所述液晶显示面板包括阵列基板，所述阵列基板包括：
第一基板；
缓冲层，设置在所述第一基板的一侧，所述缓冲层远离所述第一基板的表面设置有第一凹槽；
第一像素电极；
第二像素电极；
第三像素电极，所述第一像素电极、所述第二像素电极和所述第三像素电极依次连续排列且相互绝缘设置，所述第一像素电极、所述第二像素电极和所述第三像素电极均设置在所述缓冲层远离所述第一基板的表面，且所述第二像素电极设置在所述第一凹槽内。
相较于现有技术，本发明提供的液晶显示面板包括阵列基板，所述阵列基板包括：第一基板；缓冲层，设置在所述第一基板的一侧，所述缓冲层远离所述第一基板的表面设置有第一凹槽；第一像素电极；第二像素电极；第三像素电极，所述第一像素电极、所述第二像素电极和所述第三像素电极依次连续排列且相互绝缘设置，所述第一像素电极、所述第二像素电极和所述第三像素电极均设置在所述缓冲层远离所述第一基板的表面，且所述第二像素电极设置在所述第一凹槽内。由于第一像素电极、第二像素电极和第三像素电极依次连续排列且相互绝缘设置，且第二像素电极设置在第一凹槽内，因此，第一像素电极、第二像素电极和第三像素电极之间会形成一种凹凸起伏变化的曲面，从而可以改善相邻的像素电极交接处的电场，有助于增加横向电场，推动液晶方位角倒向，从而可以提高液晶显示面板相同开口率下的穿透率，改善液晶显示面板的显示效果。更进一步的，第一像素电极、第二像素电极和第三像素电极之间的这种凹凸起伏变化程度越大，横向电场越强，液晶倒向越好，从而可以更加显著的提高液晶显示面板相同开口率下的穿透率。
本发明还提供一种液晶显示面板制备方法，所述液晶显示面板制备方法包括：
提供第一基板；
形成覆盖在所述第一基板一侧的缓冲层；
在所述缓冲层远离所述第一基板的表面形成第一凹槽；
形成第一像素电极、第二像素电极、第三像素电极，所述第一像素电极、所述第二像素电极和所述第三像素电极依次连续排列且相互绝缘设置，所述第一像素电极、所述第二像素电极和所述第三像素电极均设置在所述缓冲层远离所述第一基板的表面，且所述第二像素电极设置在所述第一凹槽内。

为了使本发明实施例提供的技术方案更加清楚，下面结合附图对上述方案进行详细描述。
参见图1，图1是本发明实施例一提供的液晶显示面板的结构示意图。所述液晶显示面板1包括阵列基板10，所述阵列基板10包括：
第一基板100；
缓冲层200，设置在所述第一基板100的一侧，所述缓冲层200远离所述第一基板100的表面200a设置有第一凹槽310；
第一像素电极410；
第二像素电极420；
第三像素电极430，所述第一像素电极410、所述第二像素电极420和所述第三像素电极430依次连续排列且相互绝缘设置，所述第一像素电极410、所述第二像素电极420和所述第三像素电极430均设置在所述缓冲层200远离所述第一基板100的表面，且所述第二像素电极420设置在所述第一凹槽310内。
可选的，第一基板100可以为柔性基板，柔性基板可以为但不仅限于由聚酰亚胺薄膜(PI)或聚酯薄膜与铜箔复合而成。由于聚酰亚胺耐高温锡焊、高强度、高模量、阻燃等优良性能，聚酰亚胺作为高分子材料具有突出的热稳定性，良好的耐辐射和化学稳定性和优良的力学性能。
可选的，第一像素电极410、第二像素电极420和第三像素电极430可以由透明导电材料制成，所述透明导电材料可以为但不仅限于为氧化铟锡(Indium Tin Oxide，ITO)，氧化铟锡具有优良的电学传导性和光学透明性，广泛应用于制作液晶显示器、平板显示器、等离子显示器、触摸屏、电子纸、有机发光二极管、以及太阳能电池、和抗静电镀膜还有电磁干扰(Electromagnetic Interference，EMI)屏蔽的透明传导镀膜。
缓冲层200远离第一基板100的表面200a设置有第一凹槽310，第一像素电极410、第二像素电极420和第三像素电极430依次连续排列且相互绝缘设置，第一像素电极410、第二像素电极420和第三像素电极430均设置在缓冲层200远离第一基板100的表面，且第二像素电极420设置在第一凹槽310内。由于第二像素电极420设置在第一凹槽310内，第一像素电极410、第二像素电极420和第三像素电极430依次连续排列且相互绝缘设置，因此，第一像素电极410、第二像素电极420和第三像素电极430之间会形成一种凹凸起伏变化的曲面，从而可以改善相邻的像素电极交接处的电场，有助于增加横向电场，推动液晶方位角倒向，从而可以提高液晶显示面板相同开口率下的穿透率，改善液晶显示面板的显示效果。更进一步的，第一像素电极、第二像素电极和第三像素电极之间的这种凹凸起伏变化程度越大，横向电场越强，液晶倒向越好，从而可以更加显著的提高液晶显示面板1相同开口率下的穿透率。
本技术方案提供的液晶显示面板包括阵列基板，所述阵列基板包括：第一基板；缓冲层，设置在所述第一基板的一侧，所述缓冲层远离所述第一基板的 表面设置有第一凹槽；第一像素电极；第二像素电极；第三像素电极，所述第一像素电极、所述第二像素电极和所述第三像素电极依次连续排列且相互绝缘设置，所述第一像素电极、所述第二像素电极和所述第三像素电极均设置在所述缓冲层远离所述第一基板的表面，且所述第二像素电极设置在所述第一凹槽内。由于第一像素电极、第二像素电极和第三像素电极依次连续排列且相互绝缘设置，且第二像素电极设置在第一凹槽内，因此，第一像素电极、第二像素电极和第三像素电极之间会形成一种凹凸起伏变化的曲面，从而可以改善相邻的像素电极交接处的电场，有助于增加横向电场，推动液晶方位角倒向，从而可以提高液晶显示面板相同开口率下的穿透率，改善液晶显示面板的显示效果。更进一步的，第一像素电极、第二像素电极和第三像素电极之间的这种凹凸起伏变化程度越大，横向电场越强，液晶倒向越好，从而可以更加显著的提高液晶显示面板1相同开口率下的穿透率。
参见图2，图2是本发明实施例二提供的液晶显示面板的结构示意图。实施例二与实施例一的结构基本相同，不同之处在于，在实施例二中，所述阵列基板10还包括：第四像素电极440、第五像素电极450和第六像素电极460，设置在所述缓冲层200远离所述第一基板100的表面200a的第二凹槽320，所述第四像素电极440、所述第五像素电极450和所述第六像素电极460依次连续排列且相互绝缘设置，所述第四像素电极440、所述第五像素电极450和所述第六像素电极460均设置在所述缓冲层200远离所述第一基板100的表面，且所述第四像素电极440邻近所述第三像素电极430设置，所述第五像素电极450设置在所述第二凹槽320内。
可选的，在一种实施方式中，所述第三像素电极430和所述第四像素电极440之间的距离d小于预设距离值D。
具体的，将第三像素电极430和第四像素电极440之间的最大距离记为d，当第三像素电极430和第四像素电极440之间的最大距离d小于预设距离值D时，说明第三像素电极430和第四像素电极440之间的间距较小，此时，衍射作用较为显著，光线更容易穿透第一像素电极410、第二像素电极420、第三像素电极430、第四像素电极440、第五像素电极450和第六像素电极460，因此，本技术方案有助于提高液晶显示面板1的穿透率，提高液晶效率，更进 一步的，第三像素电极430和第四像素电极440之间的间距越小，横向电场越强，第三像素电极430和第四像素电极440之间的区域越不容易产生暗纹。
可选的，所述第一凹槽310的宽度d1和所述第二凹槽320的宽度d2均小于第一预设宽度值K1，且所述第一凹槽的宽度d1及所述第二凹槽d2的宽度均小于所述第三像素电极430和所述第四像素电极440之间的距离D。
其中，第一凹槽310的宽度d1与第二凹槽320的宽度d2可以相等，也可以不等。
具体的，将第一凹槽310的最大宽度记为d1，将第二凹槽320的最大宽度记为d2，当第一凹槽310的宽度d1和第二凹槽320的宽度d2均小于第一预设宽度值K1时，说明第一凹槽310的宽度d1和第二凹槽320的宽度d2都较小，说明第一凹槽310和第二凹槽320均较窄，与此同时，第一凹槽的宽度d1及第二凹槽d2的宽度均小于第三像素电极430和第四像素电极440之间的距离D，此时，衍射作用较为显著，光线更容易穿透第一像素电极410、第二像素电极420、第三像素电极430、第四像素电极440、第五像素电极450和第六像素电极460，具体的，将第一凹槽310和第二凹槽320制作的较窄的方式为：在进行光掩膜或称光罩(mask)制造时，在第一像素电极410、第三像素电极430以及第四像素电极440和第六像素电极460上增加间隙，使得第一凹槽310和第二凹槽320变得更窄的方式，利用的是光栅衍射的原理，将第三像素电极430和第四像素电极440之间的小的间距光阻曝光开，从而降低第三像素电极430和第四像素电极440的体积，提高液晶显示面板1的穿透率。因此，本技术方案有助于提高液晶显示面板1的穿透率，提高液晶效率，更进一步的，第三像素电极430和第四像素电极440之间的间距越小，横向电场越强，第三像素电极430和第四像素电极440之间的区域越不容易产生暗纹。
可选的，所述第一像素电极410、所述第三像素电极430、所述第四像素电极440和所述第六像素电极460均为条状电极，且所述第一像素电极410和所述第三像素电极430的宽度均小于第二预设宽度值K2，所述第四像素电极440和所述第六像素电极460的宽度均小于第三预设宽度值K3。
具体的，将第一像素电极410的最大宽度记为L1，将第三像素电极430的最大宽度最大记为L3，将当第四像素电极410的最大宽度记为L4，将第六 像素电极460的最大宽度记为L6，当第一像素电极410的最大宽度L1和第三像素电极430的最大宽度L3均小于第二预设宽度值K2，且第四像素电极440的最大宽度L4和第六像素电极460的最大宽度L6均小于第三预设宽度值K3时，此时，衍射作用较为显著，光线更容易穿透第一像素电极410、第二像素电极420、第三像素电极430、第四像素电极440、第五像素电极450和第六像素电极460，因此，本技术方案有助于提高液晶显示面板1的穿透率，提高相同开口率下的穿透率，更进一步的，第三像素电极430和第四像素电极440之间的间距越小，横向电场越强，第三像素电极430和第四像素电极440之间的区域越不容易产生暗纹。
换言之，理论上所述第一像素电极410和所述第三像素电极430的宽度越小，所述第四像素电极440和所述第六像素电极460的宽度越小，即表明第一像素电极410、第三像素电极430以及第四像素电极440和第六像素电极460越窄，此时，衍射作用越明显，更容易将第三像素电极430和第四像素电极440之间的间距做到目标值。可选的，第三像素电极430和第四像素电极440之间的间距主要是参照光掩膜或称光罩(mask)制造厂商的最小间距精度来设计，理论上是第三像素电极430和第四像素电极440之间的间距越小越好，具体的实现原理是：在第一像素电极410、第三像素电极430以及第四像素电极440和第六像素电极460上增加间隙，使得第一像素电极410、第三像素电极430以及第四像素电极440和第六像素电极460变得更窄的方式，利用的是光栅衍射的原理，将第三像素电极430和第四像素电极440之间的小的间距光阻曝光开，从而降低第三像素电极430和第四像素电极440的体积，提高液晶面板穿透率。
参见图3，图3是本发明实施例三提供的液晶显示面板的结构示意图。实施例三与实施例二的结构基本相同，不同之处在于，在实施例三中，所述液晶显示面板1还包括彩膜基板500和液晶层600，所述彩膜基板500设置在所述第一基板100邻近所述缓冲层200的一侧，且与所述第一基板100间隔设置；
所述彩膜基板500包括第二基板510及公共电极520，所述公共电极520设置在所述第二基板510邻近所述缓冲层200的表面200a；
所述液晶层600设置在所述阵列基板10和所述彩膜基板500之间。
其中，第一像素电极410、第二像素电极420、第三像素电极430、第四像素电极440、第五像素电极450、第六像素电极460和公共电极520共同配合，以实现控制液晶层600的偏转，从而控制液晶显示面板1发光，进而实现液晶显示面板1的显示效果。
本技术方案提供的液晶显示面板包括阵列基板，所述阵列基板包括：第一基板；缓冲层，设置在所述第一基板的一侧，所述缓冲层远离所述第一基板的表面设置有第一凹槽；第一像素电极；第二像素电极；第三像素电极，所述第一像素电极、所述第二像素电极和所述第三像素电极依次连续排列且相互绝缘设置，所述第一像素电极、所述第二像素电极和所述第三像素电极均设置在所述缓冲层远离所述第一基板的表面，且所述第二像素电极设置在所述第一凹槽内。由于第一像素电极、第二像素电极和第三像素电极依次连续排列且相互绝缘设置，且第二像素电极设置在第一凹槽内，因此，第一像素电极、第二像素电极和第三像素电极之间会形成一种凹凸起伏变化的曲面，从而可以改善相邻的像素电极交接处的电场，有助于增加横向电场，推动液晶方位角倒向，从而可以提高液晶显示面板相同开口率下的穿透率，改善液晶显示面板的显示效果。更进一步的，第一像素电极、第二像素电极和第三像素电极之间的这种凹凸起伏变化程度越大，横向电场越强，液晶倒向越好，从而可以更加显著的提高液晶显示面板相同开口率下的穿透率。
