Description

液晶显示屏及其制备方法、 显示装置 技术领域  Liquid crystal display, preparation method thereof, and display device
本发明的实施例涉及一种液晶显示屏及其制备方法、 显示装置。 背景技术  Embodiments of the present invention relate to a liquid crystal display, a method of fabricating the same, and a display device. Background technique
薄膜场效应晶体管液晶显示器 （Thin Film Transistor-Liquid Crystal Display, TFT-LCD ) 以其所具有的体积小、 功耗低、 无辐射、 制造成本相对 较低等特点， 在当前的平板显示器市场占据了主导地位。  Thin Film Transistor-Liquid Crystal Display (TFT-LCD) occupies the current flat panel display market due to its small size, low power consumption, no radiation, and relatively low manufacturing cost. leading position.
LCD属于被动发光型显示器。 由于液晶分子本身不发光，为了能使 LCD 能正常显示影像，需要利用背光模组提供亮度充足且分布均匀的光源。 目前， TFT-LCD结构可以如图 1所示，主要包括上下两块偏光片 11、彩膜基板 12、 阵列基板 13、 位于彩膜基板和阵列基板之间的液晶层 14以及背光模组 15。 背光模组 15又包括导光板 151、 反射膜 152以及背光源 153。 可以看到， 在 传统的 TFT-LCD 中， 由于受到传统背光源的限制， 显示面板周边需要具有 足够的空间设置背光源， 从而使得显示器的边框较宽， 导致周边设计复杂； 另一方面， 采用这样一种背光源的 TFT-LCD结构显示面板通常厚度较大， 难以满足人们对于显示器轻薄化的要求。 发明内容  The LCD is a passive illumination type display. Since the liquid crystal molecules do not emit light themselves, in order to enable the LCD to display images properly, it is necessary to provide a light source with sufficient brightness and uniform distribution by using the backlight module. At present, the structure of the TFT-LCD can be as shown in FIG. 1 , and mainly includes two polarizing plates 11 , a color filter substrate 12 , an array substrate 13 , a liquid crystal layer 14 between the color filter substrate and the array substrate, and a backlight module 15 . The backlight module 15 further includes a light guide plate 151, a reflective film 152, and a backlight 153. It can be seen that in the conventional TFT-LCD, due to the limitation of the conventional backlight, the periphery of the display panel needs to have enough space to set the backlight, so that the frame of the display is wider, which leads to complicated peripheral design; Such a TFT-LCD structure display panel of a backlight generally has a large thickness, and it is difficult to meet the requirements for lightening and thinning of the display.

本发明实施例提供的液晶显示屏， 如图 2所示， 包括第一基板 21、 第二 基板 22以及位于第一基板 21和第二基板 22之间的液晶层 23。  The liquid crystal display panel provided by the embodiment of the present invention, as shown in FIG. 2, includes a first substrate 21, a second substrate 22, and a liquid crystal layer 23 between the first substrate 21 and the second substrate 22.
第一基板 21外侧设置有可向第一基板 21一侧发出偏振光的偏振光光源 组件 24。 需要说明的是， 在本发明的实施例中， 基板的外侧具体是指远离液 晶层 23的一侧； 相应的， 基板的内侧具体是指靠近液晶层 23的一侧。  A polarized light source unit 24 that emits polarized light toward the first substrate 21 side is disposed outside the first substrate 21. It should be noted that, in the embodiment of the present invention, the outer side of the substrate specifically refers to the side away from the liquid crystal layer 23; correspondingly, the inner side of the substrate specifically refers to the side close to the liquid crystal layer 23.
第二基板 22上设置有偏光片 25。 例如， 如图 2所示， 偏光片 25可以设 置在第二基板 22的外侧， 即远离液晶层 23的一侧。  A polarizer 25 is disposed on the second substrate 22. For example, as shown in Fig. 2, the polarizer 25 may be disposed outside the second substrate 22, that is, away from the side of the liquid crystal layer 23.
在通电状态下， 该偏振光光源组件可以发出偏振光。 上述结构可以直接 产生线性偏振光以取代传统的背光源， 在背光源与显示结构之间也无需设置 偏光片， 从而在筒化了显示屏周边结构的同时减少了层级结构， 显著降低了 显示屏的厚度。  The polarized light source assembly can emit polarized light in an energized state. The above structure can directly generate linearly polarized light to replace the conventional backlight, and there is no need to provide a polarizer between the backlight and the display structure, thereby reducing the hierarchical structure while reducing the peripheral structure of the display screen, and significantly reducing the display screen. thickness of.
进一步地， 如图 2所示， 偏振光光源组件 24可以包括第一电极 241、 第 二电极 242和位于第一电极 241和第二电极 242之间的偏振光电致发光层 243。 在通电状态下， 该偏振光电致发光层 243 可以发出偏振光； 第一电极 241和第二电极 242中的至少一个为透明电极，该透明电极靠近液晶层 23的 一侧。  Further, as shown in FIG. 2, the polarized light source assembly 24 may include a first electrode 241, a second electrode 242, and a polarized photoluminescent layer 243 between the first electrode 241 and the second electrode 242. In the energized state, the polarized photoluminescent layer 243 can emit polarized light; at least one of the first electrode 241 and the second electrode 242 is a transparent electrode, and the transparent electrode is adjacent to one side of the liquid crystal layer 23.
第一电极 241和第二电极 242均可以采用包括氧化铟锡（ITO )或氧化 铟辞（IZO )在内的透明导电材料制成； 第一电极 241可以为阳极， 第二电 极 242可以为阴极。 这样一来， 当偏振光光源组件 24在通电状态下时， 偏振 光电致发光层 243发出的偏振光可以透过一侧的透明电极向液晶显示结构提 供背光。 当然，位于偏振光电致发光层 243两侧的电极也可以均为透明电极， 从而可以实现偏振光光源组件 24的双侧出光，一个背光源的正反两面均可以 提供背光， 从而在增加了背光源出光率的同时满足了显示面板双面显示的要 求。 The first electrode 241 and the second electrode 242 may each be made of a transparent conductive material including indium tin oxide (ITO) or indium oxide (IZO); the first electrode 241 may be an anode, and the second electrode 242 may be a cathode. . In this way, when the polarized light source assembly 24 is in the energized state, the polarized light emitted from the polarized photoluminescent layer 243 can provide backlight to the liquid crystal display structure through the transparent electrode on one side. Certainly, the electrodes on both sides of the polarizing photoluminescent layer 243 can also be transparent electrodes, so that the two sides of the polarized light source assembly 24 can be lighted out, and the backlight can be provided on both sides of the backlight, thereby increasing the backlight. The light source rate meets the requirements of the double-sided display of the display panel. begging.
进一步地， 如图 3所示， 偏振光电致发光层 243可以包括定向层 2431 和形成在定向层 2431表面的发光层 2432。  Further, as shown in FIG. 3, the polarized photoluminescence layer 243 may include an alignment layer 2431 and a light-emitting layer 2432 formed on the surface of the alignment layer 2431.
定向层 2431可以采用导电塑性材料制成。该导电塑性材料可以包括透明 的导电塑性材料， 例如包括聚苯胺、 聚 3,4-乙撑二氧噻喻或聚苯乙婦磺酸等 材料中的至少一种。例如，在实际生产的过程中，可以采用空穴聚苯胺（ PANI ) 材料形成薄膜， 再在该 PANI薄膜的表面通过摩擦取向工艺处理， 得到具有 取向方向的定向层 2431。 发光层 2432可以采用偏振电致发光材料制成。 该 偏振电致发光材料可以包括芴基聚合物， 例如芴基聚合物包括 9,9-二辛基聚 芴-苯并噻二唑交替共聚物 （PFBT ) 、 9,9-二辛基芴 -4,7-二噻喻 -2,1,3-苯并噻 二唑 -2,l,3-苯并噻二唑(PFO-BT-DBT) 等材料中的至少一种。 例如， 发光层 2432可以采用具有偏振电致发光特性的芴基聚合物材料制成， 由于芴基聚合 物及其衍生共聚物在分子结构上具有热致液晶性质， 因此由芴基聚合物材料 形成的发光层 2432可以通过具有一定取向方向的定向层 2431实现分子的有 序排列。在通电状态下，有序排列的芴基聚合物材料分子可以实现偏振发光。  The alignment layer 2431 can be made of a conductive plastic material. The electrically conductive plastic material may comprise a transparent electrically conductive plastic material, for example, at least one of polyaniline, poly 3,4-ethylenedioxythiazide or polystyrenesulfonic acid. For example, in the actual production process, a hole polyaniline (PANI) material may be used to form a film, and then the surface of the PANI film is treated by a rubbing alignment process to obtain an orientation layer 2431 having an orientation direction. The light-emitting layer 2432 can be made of a polarized electroluminescent material. The polarized electroluminescent material may comprise a fluorenyl polymer, for example a fluorenyl polymer comprising 9,9-dioctyl polyfluorene-benzothiadiazole alternating copolymer (PFBT), 9,9-dioctyl hydrazine- At least one of 4,7-dithiaxo-2,1,3-benzothiadiazole-2,l,3-benzothiadiazole (PFO-BT-DBT). For example, the light-emitting layer 2432 may be made of a ruthenium-based polymer material having polarized electroluminescence properties, and the ruthenium-based polymer and the derivative copolymer thereof have thermotropic liquid crystal properties in a molecular structure, and thus are formed of a ruthenium-based polymer material. The luminescent layer 2432 can achieve an ordered arrangement of molecules through the alignment layer 2431 having a certain orientation direction. In the energized state, the ordered array of fluorenyl polymer material molecules can achieve polarization luminescence.
进一步地， 如图 3所示， 例如偏振光光源组件 24还可以进一步包括： 位 于第一电极 241外侧的第一绝缘层 244以及位于第二电极 242外侧的第二绝 缘层 245。 进一步地， 第一绝缘层 244和第二绝缘层 245中的至少一个为透 明绝缘层， 该透明绝缘层靠近所述液晶层一侧。 这样一种透明绝缘层可以在 提高光源寿命的同时有效地提高偏振光光源组件 24的出光效率。第一绝缘层 244和第二绝缘层 245如果均采用透明绝缘层还可以使得光源的两面均可出 光， 使得显示屏的双面显示成为可能。  Further, as shown in FIG. 3, for example, the polarized light source assembly 24 may further include: a first insulating layer 244 located outside the first electrode 241 and a second insulating layer 245 located outside the second electrode 242. Further, at least one of the first insulating layer 244 and the second insulating layer 245 is a transparent insulating layer, and the transparent insulating layer is adjacent to one side of the liquid crystal layer. Such a transparent insulating layer can effectively improve the light extraction efficiency of the polarized light source unit 24 while improving the life of the light source. The use of a transparent insulating layer on both the first insulating layer 244 and the second insulating layer 245 allows both sides of the light source to be emitted, making double-sided display of the display screen possible.
绝缘层可以采用任意已知的绝缘材料制成； 透明绝缘层可以采用任意已 知的透明绝缘材料制成。 例如， 透明绝缘层可以采用玻璃或透明树脂材料制 成。通过在偏振光光源组件 24的外侧设置透明绝缘层，可以取代液晶显示结 构靠近背光源一侧的透明基板， 从而在保证液晶显示屏质量的基础上进一步 降低了液晶显示屏整体的厚度。  The insulating layer may be made of any known insulating material; the transparent insulating layer may be made of any known transparent insulating material. For example, the transparent insulating layer may be made of glass or a transparent resin material. By providing a transparent insulating layer on the outer side of the polarized light source unit 24, the transparent substrate adjacent to the backlight side of the liquid crystal display structure can be replaced, thereby further reducing the thickness of the liquid crystal display panel on the basis of ensuring the quality of the liquid crystal display.
本发明实施例还提供一种液晶显示屏， 如图 4所示， 包括第一液晶显示 面板和第二液晶显示面板， 该第一液晶显示面板与第二液晶显示面板之间设 置有可向两液晶显示面板发出偏振光的偏振光光源组件 24。 可向两液晶显示面板发出偏振光的偏振光光源组件 24 中第一电极 241 和第二电极 242均为透明电极； 第一绝缘层 244和第二绝缘层 245均为透明 绝缘层。 The embodiment of the present invention further provides a liquid crystal display panel, as shown in FIG. 4, comprising a first liquid crystal display panel and a second liquid crystal display panel, wherein the first liquid crystal display panel and the second liquid crystal display panel are disposed to The liquid crystal display panel emits a polarized light source assembly 24 that is polarized. The first electrode 241 and the second electrode 242 of the polarized light source assembly 24 that can emit polarized light to both liquid crystal display panels are transparent electrodes; the first insulating layer 244 and the second insulating layer 245 are both transparent insulating layers.
第一液晶显示面板的结构可以如图 2所示， 包括第一基板 21、 第二基板 22以及位于第一基板 21和第二基板 22之间的液晶层 23。第二液晶显示面板 的结构可以参照第一液晶显示面板的结构， 而且还可以包括： 位于偏振光光 源组件 24另一侧的第三基板 26。  The structure of the first liquid crystal display panel may be as shown in FIG. 2, and includes a first substrate 21, a second substrate 22, and a liquid crystal layer 23 between the first substrate 21 and the second substrate 22. The structure of the second liquid crystal display panel may refer to the structure of the first liquid crystal display panel, and may further include: a third substrate 26 located on the other side of the polarized light source unit 24.
第四基板 27和第三基板 26彼此相对设置形成液晶盒（ cell ) , 该第四基 板 27和第三基板 25之间具有液晶层 23。  The fourth substrate 27 and the third substrate 26 are disposed opposite to each other to form a liquid crystal cell, and the liquid crystal layer 23 is provided between the fourth substrate 27 and the third substrate 25.
该第四基板 27的外侧设置有偏光片 28。 在这种结构的液晶显示屏中， 偏振光光源组件的两侧均形成有液晶显示结构， 且位于偏振光光源组件两侧 的两个液晶显示结构可以相同。 这样保证了偏振光光源组件发出的线性偏振 光能够分别从两侧出射， 实现了液晶显示屏的双面显示。  A polarizer 28 is disposed outside the fourth substrate 27. In the liquid crystal display panel of this structure, a liquid crystal display structure is formed on both sides of the polarized light source unit, and the two liquid crystal display structures on both sides of the polarized light source unit can be the same. This ensures that the linearly polarized light emitted by the polarized light source component can be emitted from both sides, thereby realizing double-sided display of the liquid crystal display.
本发明实施例提供的液晶显示屏， 该液晶显示屏包括第一液晶显示面板 和第二液晶显示面板， 该第一液晶显示面板与第二液晶显示面板之间设置有 可向两液晶显示面板发出偏振光的偏振光光源组件。 在通电状态下， 偏振光 光源组件可以发出偏振光。 这种结构可以直接产生线性偏振光以取代传统的 背光源， 在背光源与显示结构之间也无需设置偏光片， 从而在筒化了显示屏 周边结构的同时减少了层级结构， 显著降低了显示屏的厚度。 此外， 这样一 种结构的液晶显示屏还能够实现双侧显示效果， 与现有的双侧显示屏相比， 具有更少的层级结构， 进一步降低了双侧显示屏的整体厚度。  The liquid crystal display panel of the embodiment of the invention includes a first liquid crystal display panel and a second liquid crystal display panel, and the first liquid crystal display panel and the second liquid crystal display panel are disposed to be sent to the two liquid crystal display panels A polarized light source assembly. The polarized light source assembly can emit polarized light when the power is on. This structure can directly produce linearly polarized light to replace the traditional backlight, and there is no need to provide a polarizer between the backlight and the display structure, thereby reducing the hierarchical structure while reducing the surrounding structure of the display screen, and significantly reducing the display. The thickness of the screen. In addition, the liquid crystal display of such a structure can achieve a double-sided display effect, and has a smaller hierarchical structure than the existing two-sided display screen, further reducing the overall thickness of the double-sided display screen.
需要说明的是， 在上述发明实施例中， 第一液晶显示面板中的第一基板 和第二基板可以分别是阵列基板或彩膜基板； 同样， 第二液晶显示面板中的 第三基板和第四基板也可以分别是阵列基板或彩膜基板。  It should be noted that, in the foregoing embodiments of the present invention, the first substrate and the second substrate in the first liquid crystal display panel may be an array substrate or a color film substrate, respectively; likewise, the third substrate and the second in the second liquid crystal display panel The four substrates may also be array substrates or color film substrates, respectively.
阵列基板可以采用现有的任意一种结构，本发明对此并不作限制。例如， 阵列基板可以采用 FFS ( Fringe Field Switching, 边缘场开关）型的阵列基板， 或者可以采用 ADS ( Advanced-Super Dimensional Switching, 高级超维场开 关）型的阵列基板， 在本发明实施例中， 可以以 ADS 型的阵列基板为例进 行的说明。  The array substrate can be any one of the existing structures, and the present invention is not limited thereto. For example, the array substrate may be an array substrate of an FFS (Fringe Field Switching) type, or an array substrate of an ADS (Advanced-Super Dimensional Switching) type may be used. In the embodiment of the present invention, The description can be made by taking an ADS type array substrate as an example.
ADS技术是通过同一平面内像素电极边缘所产生的平行电场以及像素 电极层与异层设置的公共电极层间产生的纵向电场形成多维电场， 使液晶盒 内像素电极间、 电极正上方所有取向液晶分子都能够产生旋转转换， 从而提 高了平面取向系液晶工作效率并增大了透光效率。 异层设置是针对至少两种 图案而言的， 至少两种图案异层设置是指， 分别将至少两层薄膜通过构图工 艺形成至少两种图案。 对于两种图案异层设置是指， 通过构图工艺， 由两层 薄膜各形成一种图案。 例如， 公共电极和像素电极异层设置是指： 由第一层 透明导电薄膜通过构图工艺形成下层电极， 由第二层透明导电薄膜通过构图 工艺形成上层电极。 下层电极为公共电极（或像素电极） ， 上层电极为像素 电极（或公共电极） 。 ADS technology is a parallel electric field generated by the edge of a pixel electrode in the same plane and a pixel The longitudinal electric field generated between the electrode layer and the common electrode layer disposed in the different layer forms a multi-dimensional electric field, so that all the aligned liquid crystal molecules between the pixel electrodes in the liquid crystal cell and directly above the electrode can be rotated, thereby improving the working efficiency of the planar orientation liquid crystal. Increased light transmission efficiency. The different layer arrangement is for at least two patterns, and the at least two pattern different layer arrangement means that at least two layers of the film are respectively formed into at least two patterns by a patterning process. For the two-pattern different layer arrangement, it is meant that a pattern is formed by each of the two films by a patterning process. For example, the common electrode and the pixel electrode different layer arrangement means that the lower layer electrode is formed by the patterning process from the first layer of the transparent conductive film, and the upper layer electrode is formed by the patterning process by the second layer of the transparent conductive film. The lower electrode is a common electrode (or a pixel electrode), and the upper electrode is a pixel electrode (or a common electrode).
例如， 当第一基板 21和第三基板 26为 ADS模式的阵列基板时， 如图 5 所示， 第一基板 21和第三基板 26可以包括异层设置的梳状的像素电极 51 和梳状的公共电极 52。例如，像素电极 51和公共电极 52之间具有绝缘层 53。  For example, when the first substrate 21 and the third substrate 26 are array substrates of the ADS mode, as shown in FIG. 5, the first substrate 21 and the third substrate 26 may include comb-shaped pixel electrodes 51 and combs disposed in different layers. Common electrode 52. For example, an insulating layer 53 is provided between the pixel electrode 51 and the common electrode 52.
需要说明的是， 在本发明实施例中， 对像素电极 51和公共电极 52的上 下层关系并不作限制。 可以理解， 在如图 5所示的阵列基板中， 是以像素电 极 51位于公共电极 52的外层为例进行的说明的。  It should be noted that, in the embodiment of the present invention, the relationship between the upper and lower layers of the pixel electrode 51 and the common electrode 52 is not limited. It can be understood that, in the array substrate shown in Fig. 5, the pixel electrode 51 is located on the outer layer of the common electrode 52 as an example.
进一步地， 例如， 第一基板 21和第三基板 26靠近液晶一侧表面均具有 第一钝化层 54。 这样可以有效隔离阵列基板和液晶， 从而防止液晶分子对阵 列基板的影响， 保证了显示装置的质量。  Further, for example, the first substrate 21 and the third substrate 26 have a first passivation layer 54 near the liquid crystal side surface. This can effectively isolate the array substrate and the liquid crystal, thereby preventing the influence of the liquid crystal molecules on the array substrate, and ensuring the quality of the display device.
进一步地， 同样参照图 5所示，第二基板 22和第四基板 27为彩膜基板， 第二基板 22和第四基板 27例如可以包括： 透明基板 55, 该透明基板 55的 一侧可以设置有偏光片， 另一侧设置有彩色滤光层 56。  Further, referring to FIG. 5, the second substrate 22 and the fourth substrate 27 are color film substrates, and the second substrate 22 and the fourth substrate 27 may include, for example, a transparent substrate 55, one side of which may be disposed. There is a polarizer, and the other side is provided with a color filter layer 56.
在本发明实施例中，如图 5所示，第二基板 22可以位于偏振光光源组件 24的上方， 第四基板 27可以位于偏振光光源组件 24的下方， 第二基板 22 和第四基板 27均具有透明基板 55。 在第二基板 22中的透明基板 55的上表 面设置偏光片 25 , 其下表面设置有彩色滤光层 56, 第四基板 27可以与第二 基板 22对称设置， 即第四基板 27的透明基板 55的下表面设置偏光片 28, 其上表面设置彩色滤光层 56。 需要说明的是， 透明基板 55可以采用玻璃或 树脂等已知的透明材料制成， 彩色滤光层 56 内可以分别形成有例如红绿蓝 ( RGB )三色的彩色滤光结构以及黑矩阵区域。  In the embodiment of the present invention, as shown in FIG. 5, the second substrate 22 may be located above the polarized light source assembly 24, and the fourth substrate 27 may be located below the polarized light source assembly 24, the second substrate 22 and the fourth substrate 27 Each has a transparent substrate 55. A polarizing plate 25 is disposed on the upper surface of the transparent substrate 55 in the second substrate 22, and a color filter layer 56 is disposed on the lower surface thereof, and the fourth substrate 27 can be symmetrically disposed with the second substrate 22, that is, the transparent substrate of the fourth substrate 27. A polarizing plate 28 is disposed on the lower surface of the 55, and a color filter layer 56 is disposed on the upper surface thereof. It should be noted that the transparent substrate 55 may be made of a known transparent material such as glass or resin, and the color filter layer 56 may be respectively formed with a color filter structure of three colors of red, green and blue (RGB) and a black matrix region. .
例如彩色滤光层 56的另一侧可以具有第二钝化层 57。 这样可以有效隔 离彩膜基板和液晶， 从而防止液晶分子对彩膜基板的影响， 保证了显示装置 的质量。 For example, the other side of the color filter layer 56 may have a second passivation layer 57. This can effectively separate The color film substrate and the liquid crystal are separated, thereby preventing the influence of the liquid crystal molecules on the color filter substrate, and the quality of the display device is ensured.
通过这种结构， 偏振光光源组件可以直接产生线性偏振光以取代传统的 背光源， 在偏振光光源组件与两个显示结构之间也无需设置偏光片， 从而在 筒化了显示面板周边结构的同时减少了双面显示液晶显示屏的层级结构， 显 著降低了双面显示液晶显示屏的厚度。  With this structure, the polarized light source assembly can directly generate linearly polarized light to replace the conventional backlight, and there is no need to provide a polarizer between the polarized light source assembly and the two display structures, thereby squeezing the peripheral structure of the display panel. At the same time, the hierarchical structure of the double-sided display liquid crystal display is reduced, and the thickness of the double-sided display liquid crystal display is significantly reduced.
本发明实施例提供一种显示装置， 其包括上述任意一种液晶显示屏。 所 述显示装置可以为： 手机、 平板电脑、 电视机、 显示器、 笔记本电脑、 照相 机、 摄像机、 数码相框、 导航仪等任何具有显示功能的产品或部件。  Embodiments of the present invention provide a display device including any one of the above liquid crystal displays.

In the energized state, the polarized light source assembly can emit polarized light. This structure can directly produce linearly polarized light to replace the traditional backlight, and there is no need to provide a polarizer between the backlight and the display structure, thereby reducing the hierarchical structure while reducing the surrounding structure of the display screen, and significantly reducing the display. The thickness of the screen.
第一电极和第二电极均可以采用包括氧化铟锡（ ITO )或氧化铟辞（ IZO ) 在内的透明导电材料制成， 第一电极可以为阳极， 第二电极可以为阴极。 这 样一来， 当偏振光光源组件在通电状态下时， 偏振光电致发光层发出的偏振 光可以透过一侧的透明电极向液晶显示结构提供背光。 当然， 位于偏振光电 致发光层两侧的电极也可以均为透明电极， 从而可以实现偏振光光源组件的 双侧送光， 一个背光源的正反两面均可以提供背光， 从而在增加了背光源出 光率的同时满足了显示面板双面显示的要求。 The first electrode and the second electrode may each be made of a transparent conductive material including indium tin oxide (ITO) or indium oxide (IZO), the first electrode may be an anode, and the second electrode may be a cathode. In this way, when the polarized light source assembly is in an energized state, the polarized light emitted by the polarized photoluminescent layer can provide backlight to the liquid crystal display structure through the transparent electrode on one side. Of course, the electrodes on both sides of the polarizing photoluminescent layer may also be transparent electrodes, so that the polarized light source assembly can be realized.

The conductive plastic material may comprise a transparent conductive plastic material, for example, at least one of polyaniline, poly 3,4-ethylenedioxythiophene or polystyrene sulfonic acid. For example, in the actual production process, a film of a polyaniline (PANI) material may be used to form a film, and the surface of the PANI film is treated by a rubbing alignment process to obtain an alignment layer 2431 having an orientation direction. The light-emitting layer 2432 can be made of a polarized electroluminescent material. The polarized electroluminescent material may comprise a fluorenyl polymer, for example a fluorenyl polymer comprising 9,9-dioctyl polyfluorene-benzothiadiazole alternating copolymer (PFBT), 9,9-dioctyl hydrazine- At least one of materials such as 4,7-dithiophene-2,1,3-benzothiadiazole-2,l,3-benzothiadiazole (PFO-BT-DBT). For example, the light-emitting layer 2432 may be made of a ruthenium-based polymer material having polarized electroluminescence properties, and the ruthenium-based polymer and the derivative copolymer thereof have thermotropic liquid crystal properties in a molecular structure, and thus are formed of a ruthenium-based polymer material. The luminescent layer 2432 can achieve an ordered arrangement of molecules through the alignment layer 2431 having a certain orientation direction. In the energized state, the ordered array of fluorenyl polymer material molecules can achieve polarization luminescence.
例如， 偏振光光源组件还可以包括： 位于第一电极外侧的第一绝缘层以 及位于第二电极外侧的第二绝缘层。 第一绝缘层和第二绝缘层中的至少一个 为透明绝缘层， 该透明绝缘层靠近液晶层一侧。 当然， 所述第一绝缘层和第 二绝缘层也可以均为透明绝缘层，从而可以实现偏振光光源组件的双侧送光， 满足了显示面板双面显示的要求。 例如， 绝缘层可以采用任意已知的绝缘材 料制成； 透明绝缘层可以采用任意已知的透明绝缘材料制成。 例如， 第一绝 缘层和第二绝缘层均可以采用玻璃或透明树脂材料制成。 通过在偏振光光源 组件的外侧设置透明绝缘层， 可以取代液晶显示结构靠近背光源一侧的透明 基板， 从而在保证液晶显示屏质量的基础上进一步降低了液晶显示屏整体的 厚度。  For example, the polarized light source assembly may further include: a first insulating layer located outside the first electrode and a second insulating layer located outside the second electrode. At least one of the first insulating layer and the second insulating layer is a transparent insulating layer which is adjacent to one side of the liquid crystal layer. Of course, the first insulating layer and the second insulating layer may also be transparent insulating layers, so that the two-side light transmission of the polarized light source assembly can be realized, which satisfies the requirements of the double-sided display of the display panel. For example, the insulating layer may be made of any known insulating material; the transparent insulating layer may be made of any known transparent insulating material. For example, both the first insulating layer and the second insulating layer may be made of glass or a transparent resin material. By providing a transparent insulating layer on the outer side of the polarized light source component, the transparent substrate adjacent to the backlight side of the liquid crystal display structure can be replaced, thereby further reducing the thickness of the liquid crystal display panel on the basis of ensuring the quality of the liquid crystal display.
进一步地， 在制作偏振光光源组件之后， 液晶显示屏制备方法还包括如 下步骤：  Further, after the polarized light source assembly is fabricated, the liquid crystal display manufacturing method further includes the following steps:

该第四基板 27的外侧设置有偏光片 28, 在这样一种结构的液晶显示屏 中， 偏振光光源组件的两侧均形成有液晶显示结构。 例如， 位于偏振光光源 组件两侧的两个液晶显示结构可以相同， 这样一来， 保证了偏振光光源组件 发出的线性偏振光能够分别从两侧出射， 实现了液晶显示屏的双面显示。  A polarizing plate 28 is disposed on the outer side of the fourth substrate 27. In the liquid crystal display panel of such a structure, a liquid crystal display structure is formed on both sides of the polarized light source assembly. For example, the two liquid crystal display structures on both sides of the polarized light source component can be the same, so that the linearly polarized light emitted by the polarized light source component can be separately emitted from both sides, thereby realizing double-sided display of the liquid crystal display.
本发明实施例提供的液晶显示屏中， 这种结构可以直接产生线性偏振光 以取代传统的背光源， 在背光源与显示结构之间也无需设置偏光片， 从而在 筒化了显示屏周边结构的同时减少了层级结构， 显著降低了显示屏的厚度。 此外， 这样一种结构的液晶显示屏还能够实现双侧显示效果， 与现有的双侧 显示屏相比， 具有更少的层级结构， 进一步降低了双侧显示屏的整体厚度。  In the liquid crystal display provided by the embodiment of the invention, the structure can directly generate linearly polarized light to replace the traditional backlight, and there is no need to provide a polarizer between the backlight and the display structure, thereby squeezing the peripheral structure of the display screen.
