Definitions

  • the invention belongs to the field of flexible display technologies, and in particular relates to a flexible display panel and a flexible display.
  • LCD Liquid Crystal Display
  • the liquid crystal panel is a key component in the liquid crystal display.
  • the liquid crystal panel is mainly formed by a color film substrate and an array substrate.
  • the color film substrate and the array substrate are filled with liquid crystal to form a liquid crystal cell.
  • the liquid crystal is required to have a function of changing the polarization state of the light, that is, the optical retardation generated by the liquid crystal is changed, and the polarization state of the light is changed, thereby realizing light and dark display.
  • the change in the polarization state of the light of the liquid crystal is in turn dependent on the optical retardation amount ⁇ nd of the liquid crystal (where ⁇ n is the difference in refractive index between the slow axis and the fast axis of the liquid crystal, and d is the thickness of the liquid crystal cell).
  • ⁇ n is the difference in refractive index between the slow axis and the fast axis of the liquid crystal
  • d is the thickness of the liquid crystal cell.
  • the thickness d of the entire liquid crystal cell should be the same, so as to ensure the controllability and uniformity of the display effect. Therefore, the control of the thickness of the liquid crystal cell is critical to the liquid crystal display.
  • the technical problem to be solved by the present invention is to provide a flexible display panel and a flexible display capable of avoiding display defects due to uneven thickness of the liquid crystal cell, in view of the problem of uneven thickness of the liquid crystal cell of the conventional flexible display panel.
  • the technical solution adopted to solve the technical problem to be solved by the present invention is a soft
  • the display panel includes a first flexible substrate and a second flexible substrate that are opposed to each other.
  • the flexible display panel further includes: a blue phase liquid crystal layer disposed between the first flexible substrate and the second flexible substrate; disposed on a side of the second flexible substrate facing away from the blue phase liquid crystal layer a reflective layer and a strip electrode disposed on a side of the second flexible substrate adjacent to the blue phase liquid crystal layer; and sequentially disposed on the first flexible substrate facing away from the blue phase liquid crystal layer a quarter-wave plate and a polarizer on one side, and an angle between a transmission axis of the polarizer and an optical axis of the quarter-wave plate is 45 degrees, the strip electrode and the The angle of the optical axis of the quarter wave plate is 90 degrees.
  • the reflective layer is disposed on a side of the second flexible substrate facing away from the blue phase liquid crystal layer, when ambient light passes through the first flexible substrate, the blue phase liquid crystal layer, and the second flexible substrate, After the reflective layer, the reflective layer can reflect the ambient light to the direction of the first flexible substrate, that is, the ambient light is equivalent to the backlight. At this time, the liquid crystal display panel is applied to the liquid crystal display without a backlight. The production cost of the liquid crystal display is lowered.
  • the liquid crystal filled between the first flexible substrate and the second flexible substrate is a blue phase liquid crystal layer, wherein the blue phase is a liquid crystal phase between the isotropic state and the cholesteric phase, due to the blue phase liquid crystal
  • the molecular stability is high, and the blue phase liquid crystal is in an isotropic state without being affected by an electric field. Therefore, applying the blue phase liquid crystal to the display panel can make the liquid crystal display panel have a large viewing angle and a dark state.
  • the characteristic is that, at the same time, since the blue phase liquid crystal can generate birefringence after power-on, the liquid crystal display panel does not need an orientation layer (ie, an alignment film) which is necessary for other types of liquid crystal display panels, thereby reducing manufacturing cost. Simplifies the manufacturing process.
  • the theoretical response time of the liquid crystal display panel using the blue phase liquid crystal can reach below the millisecond level, thereby greatly improving the response time, so that it is possible to control different colors by timing control without preparing a color filter layer on the first flexible substrate. Display. Therefore, the liquid crystal display panel using the blue phase liquid crystal has higher contrast ratio, faster response time, and wider viewing angle than the ordinary liquid crystal display panel, and greatly improves the display quality of the liquid crystal display panel.
  • this type of liquid crystal display panel has the disadvantage of requiring a relatively high driving voltage and low light efficiency.
  • the photoelectric properties of the blue phase liquid crystal are thicker for the liquid crystal cell. The degree is not sensitive.

Description

柔性显示面板和柔性显示器 技术领域
本发明属于柔性显示技术领域，具体涉及柔性显示面板和柔性显示器。
背景技术
目前，液晶显示器(Liquid Crystal Display，简称LCD)以其优异的性能与成熟的技术成为市场上的主流显示器产品。
液晶面板是液晶显示器中的关键部件，液晶面板主要由彩膜基板和阵列基板对盒而成，所述彩膜基板和所述阵列基板之间填充液晶而构成液晶盒。液晶面板要实现正常的显示，就要求液晶具有对光的偏振态的改变功能，即使得经过液晶产生的光学延迟，光的偏振态发生改变，从而实现明暗显示。而液晶的这种对光的偏振态的改变作用又取决于液晶的光学延迟量Δnd(其中，Δn为液晶慢轴和快轴方向折射率的差值，d为液晶盒的厚度)。理想状况下，整个液晶盒的厚度d应该是相同的，这样才能保证显示效果的可控性和均匀性。因此，液晶盒的厚度的控制对液晶显示器来说至关重要。
此外，为了满足市场的需求，关于柔性显示的研究和柔性显示产品越来越多，柔性液晶显示器也被广泛研究和尝试。对柔性液晶显示器而言，其中的一个关键问题就是挠曲时液晶盒的厚度d很难维持，从而很难保证显示效果的可控性和均匀性。
发明内容
本发明所要解决的技术问题是针对现有的柔性显示面板的液晶盒的厚度不均的问题，提供一种能够避免由于液晶盒的厚度不均而产生显示不良的柔性显示面板和柔性显示器。
解决本发明所要解决的技术问题所采用的技术方案是一种柔 性显示面板，其包括相互对盒的第一柔性基板和第二柔性基板。该柔性显示面板还包括：设置在所述第一柔性基板和所述第二柔性基板之间的蓝相液晶层；设置在所述第二柔性基板的背离所述蓝相液晶层的一侧上的反射层和间隔设置在所述第二柔性基板的靠近所述蓝相液晶层的一侧上的条状电极；以及，依次设置在所述第一柔性基板的背离所述蓝相液晶层的一侧上的四分之一波片和偏光片，且所述偏光片的透光轴与所述四分之一波片的光轴的夹角为45度，所述条状电极与所述四分之一波片的光轴的夹角为90度。
在本发明中，由于在第二柔性基板的背离蓝相液晶层的一侧上设置有反射层，因此，当外界环境光通过第一柔性基板、蓝相液晶层、第二柔性基板而照射到反射层后，反射层可以将环境光反射到第一柔性基板所在方向，也就说，外界环境光就相当于背光源，此时将该液晶显示面板应用于液晶显示器中，无需背光源，从而降低了液晶显示器的生产成本。同时，在第一柔性基板和第二柔性基板之间填充的液晶为蓝相液晶层，其中，蓝相是介于各向同性态与胆甾相之间的一种液晶相，由于蓝相液晶的分子稳定性高，并且在不受电场作用的情况下，蓝相液晶为各向同性态，因此将蓝相液晶应用于显示面板中，可使得该液晶显示面板具有视角大、暗态好的特点，同时，由于在加电后蓝相液晶可产生双折射的特点，使得该液晶显示面板不需要其他类型的液晶显示面板所必需采用的取向层(即配向膜)，从而降低了制造成本，简化了制造工艺。而且，采用蓝相液晶的液晶显示面板的理论响应时间可达到毫秒级以下，从而大大的提高了响应时间，所以可以无需在第一柔性基板上制备彩色滤光层而通过时序控制来控制不同颜色的显示。因此，采用蓝相液晶的液晶显示面板比普通的液晶显示面板具有更高的对比度、更快的响应时间以及更宽的观看视角，极大的提升了液晶显示面板的显示质量。但是，这种类型的液晶显示面板存在所需的驱动电压相对较高、光效率较低的缺点。然而，最主要的是，由于蓝相液晶的光电特性对液晶盒的厚 度不敏感，因此，当柔性显示面板发生弯曲时，即使液晶盒的厚度发生变化也不会对显示效果影响很大，从而可以解决柔性显示面板由于液晶盒的厚度不均引起显示效果变差的问题。
优选的是，所述条状电极包括像素电极和公共电极，其中，所述像素电极和所述公共电极等间距间隔设置。
优选地，在所述第二柔性基板的靠近所述蓝相液晶层的一侧还设置有板状电极，所述条状电极设置在所述板状电极上方、并通过绝缘层与所述板状电极隔开，其中，所述板状电极为像素电极，所述条状电极为公共电极；或者，所述板状电极公共电极，所述条状电极为像素电极。
优选的是，所述条状电极的宽度为2μm至5μm之间，所述条状电极之间的间距为4μm至10μm之间。
优选的是，所述第一柔性基板与所述第二柔性基板形成的液晶盒的厚度为2μm至5μm之间。

进一步优选的是，所述第一柔性基板还包括设于所述第一柔性基底与所述四分之一波片之间的彩色滤光层。
优选的是，所述反射层的材料为铝或银。
解决本发明所要解决的技术问题所采用的技术方案是一种柔性显示器，其包括上述柔性显示面板。
由于本发明的柔性显示器包括上述柔性显示面板，故其可以避免液晶盒的厚度不均对显示品质造成的影响且生产成本低。
优选的是，该柔性显示器还包括前置光源，所述前置光源设于所述柔性显示器的前框上。

具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面参照附图和具体实施方式对本发明作进一步详细描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，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发明保护的范围。
实施例1：
参照图1和图2，本实施例提供一种柔性显示面板，其包括相互对盒的第一柔性基板100和第二柔性基板200、以及设置在第一柔性基板100和第二柔性基板200之间的蓝相液晶层300。该柔性显示面板还包括：设置在所述第二柔性基板200的背离所述蓝相液晶层300的一侧上的反射层201和间隔设置在所述第二柔性基板200的靠近所述蓝相液晶层300的一侧上的条状电极；以及，依次设置在第一柔性基板100的背离所述蓝相液晶层300的一侧上的四分之一波片101和偏光片102，且偏光片102的透光轴与四分之一波片101的光轴的夹角为45度，所述条状电极与四分之一波片101的光轴的夹角为90度。
在本实施例中，由于在第二柔性基板200的背离蓝相液晶层300的一侧上设置有反射层201，因此，当外界环境光通过第一柔性基板100、蓝相液晶层300、第二柔性基板200而照射到反射层201后，反射层201可以将环境光反射到第一柔性基板100所在方向，也就说，外界环境光就相当于背光源，此时将该液晶显示面板应用于液晶显示器中，无需背光源，从而降低了液晶显示器的生产成本。同时，在第一柔性基板100和第二柔性基板200之间填充的液晶为蓝相液晶，其中，蓝相是介于各向同性态与胆甾相 之间的一种液晶相，由于蓝相液晶的分子稳定性高，并且在不受电场作用的情况下，蓝相液晶为各向同性态，因此将蓝相液晶应用于显示面板中，可使得该液晶显示面板具有视角大、暗态好的特点，同时，由于在加电后蓝相液晶可以产生双折射的特点，使得该液晶显示面板不需要其他类型的液晶显示面板所必须采用的取向层(即配向膜)，从而降低了制造成本，简化了制造工艺。而且，采用蓝相液晶的液晶显示面板的理论响应时间可达到毫秒级以下，从而大大的提高了响应时间，所以可以无需在第一柔性基板100上制备彩色滤光层而通过时序控制来控制不同颜色的显示。因此，采用蓝相液晶的液晶显示面板比普通的液晶显示面板具有更高的对比度、更快的响应时间以及更宽的观看视角，极大的提升了液晶显示面板的显示质量。但是，这种类型的液晶显示面板存在所需的驱动电压相对较高、光效率较低的缺点。然而，最主要的是，由于蓝相液晶的光电特性对液晶盒的厚度不敏感，因此，当柔性显示面板发生弯曲时，即使液晶盒的厚度发生变化也不会对显示效果影响很大，从而可以解决柔性显示面板由于液晶盒的厚度不均引起显示效果变差的问题。
本实施例中，由于采用蓝相液晶层300，所以该柔性显示面板需要在第二柔性基板200上形成类似横向电场模式的电极结构。所述横向电场模式例如但不限于是IPS(In-Plane Switching，平面内切换)模式或ADS(Advanced Super Dimension Switch，高级超维场转换)模式。
具体的，在本实施例中，优选地，在所述第二柔性基板200的靠近所述蓝相液晶层300的一侧上间隔设置的条状电极包括：像素电极202和公共电极203，其中，所述像素电极202和所述公共电极203等间距间隔设置，且所述像素电极202和所述公共电极203的形状和尺寸均完全相同，即，各条状电极的长度相等、宽度相等、厚度相等。该电极结构形成的电场模式是IPS模式。进一步优选地，所述条状电极的宽度在2μm至5μm之间，所述像素电极202和所述公共电极203之间的间距在4μm至10μm之间。
由于像素电极202和公共电极203的形状和尺寸均完全相同，且同层等间距设置，故在像素电极202和公共电极203之间形成的电场是均匀分布的，若忽略电场的边沿效应，可认为电场沿条状电极的排列方向是周期分布的。
当然，在本实施例中，优选地，还可以在所述第二柔性基板200的靠近所述蓝相液晶层300的一侧上设置板状电极，所述条状电极设置在所述板状电极上方并通过绝缘层与所述板状电极隔开，其中，所述板状电极为像素电极202，此时所述条状电极为公共电极203；或者所述条状电极为像素电极202，所述板状电极为公共电极203。该电极结构形成的电场模式是ADS模式。ADS模式的电场与IPS模式的电场相类似，在此不再详细描述。
在本实施例中，为了使得柔性显示面板更加轻薄，优选地，所述第一柔性基板100与所述第二柔性基板200形成的液晶盒的厚度在2μm至5μm之间。
在本实施例中，所述第一柔性基板100包括第一柔性基底，所述第二柔性基板200包括第二柔性基底，其中，所述第一柔性基底和所述第二柔性基底的材料均为聚对苯二甲酸乙二醇酯、邻苯二甲酸酯、聚酰亚胺中的任意一种。当然，也可以采用其他柔性耐高温(400摄氏度)的树脂材料来形成所述第一柔性基底和所述第二柔性基底。
为了使显示效果更好，本实施中，优选地，所述第一柔性基板100还包括设于第一柔性基底与四分之一波片101之间的彩色滤光层。
本实施例中，第二柔性基板200的远离蓝相液晶层300的一侧上的反射层201的材料可以为铝或银，或者也可以是由其他的反射性材料制成。
以下对本实施例的柔性显示面板的工作过程进行描述。
图1为本实施例中的反射式柔性显示面板不加电压时的示意图。在不加电压时，蓝相液晶呈光学各向同性态,即各个方向的折射率都是一样的，如图1所示，此时蓝相液晶的折射率分布可等 效为圆形。在本实施例中，偏光片102的透光轴与所述四分之一波片101的光轴的夹角为45度。在此，假设偏光片102的透光轴为45°，四分之一波片101的光轴为0°。此时，当外界环境光入射后，经过偏光片102成为45°的线性偏振光，该45°的线性偏振光经过0°放置的四分之一波片101，偏振态改变90°而成为左旋圆偏振光，该左旋圆偏振光经过各向同性的蓝相液晶后不发生任何偏振态的改变，继续传播到反射层201，被反射层201反射后，左旋圆偏光成为右旋圆偏光，该右旋圆偏光再次经过各向同性的蓝相液晶后不发生任何偏振态的改变，继续传播，经过0°放置的四分之一波片101，右旋圆偏光的偏振态改变90°而成为-45°的线性偏振光，该线性偏振光与偏光片102的透过轴正交而无法透过偏光片102，此时柔性显示面板呈暗态。
图2为本实施例中的柔性显示面板在被施加电压时的示意图。加电时，蓝相液晶可等效被看成拉伸粒状，且蓝相液晶的长轴与电场方向一致。由于条状电极与四分之一波片101的光轴成90度夹角，电场方向与条状电极方向垂直,因此蓝向液晶的长轴与四方之一波片101的光轴平行。此时，蓝相液晶各向异性，根据双折射原理(克尔效应)，其会对通过的光产生光学延迟。根据克尔效应，Δn＝λKE2，其中λ为入射光波长，K为克尔常数(K＝12.68nm/V2)，E为电场强度，其数值等于电极间电压U除以液晶盒的厚度d。此外，在给柔性显示面板施加一定电压的情况下，当光经过蓝相液晶而产生Δnd＝λ/4的延迟量时，光的相位改变π/2，则左旋偏振光会成为线性偏振光。因此，在给柔性显示面板施加一定电压的情况下，环境光入射后，经过偏光片102成为45°的线性偏振光，该线性偏振光经过0°放置的四分之一波片101，偏振态改变90°，成为左旋圆偏振光，该左旋圆偏振光经过其长轴为0°且其产生的光学延迟量为λ/4的蓝相液晶层300后转变成-45°的线性偏振光，继续传播到反射层201，被反射层201反射后，线性偏振光无变化，-45°的线性偏振光再次经过其光学延迟量为λ/4的蓝相液晶层300和四分之一波片101后，偏振态改 变90°而成为45°的线性偏振光，该45°的线性偏振光可以从偏光片102射出。此时，柔性显示面板为亮态。由此，不难看出，可以通过控制施加电压大小来控制Δnd的大小，进而得到不同的灰阶。
需要说明的是，在本实施例中，仅仅是以偏光片102的透光轴为45°、四分之一波片101的光轴为0°、蓝相液晶的光学延迟量为四分之一个波长为例对柔性显示面板的工作状态进行说明，当然，实际上，只要是偏光片102的透光轴与所述四分之一波片101的光轴的夹角为45度即可，在此不一一说明。
实施例2：
本实施例提供一种柔性显示器，其包括上述柔性显示面板，该柔性显示器可以为手机、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。
优选地，本实施例的柔性显示器还包括前置光源，所述前置光源设于所述柔性显示器的前框上，该前置光源可以将光照射到柔性显示面板上，这样，即使在黑暗环境中也可以进行显示。
本实施例的柔性显示器中具有实施例1中的柔性显示面板，故其成本较低。
当然，本实施例的柔性显示器中还可以包括其他常规结构，如电源单元、显示驱动单元等。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
