【具体实施方式】
下面将结合本发明实施例中的附图，对本发明所提供的示例性的实施例的技术方案进行清楚、完整地描述。
图1是本发明的液晶显示器一实施例的结构示意图。如图1所示，所述液晶显示器10包括背光源11、调光片材12以及显示面板13，调光片材12位于显示面板13的如箭头所示的入光方向上，背光源11可以由均匀设置于一板材上的多个光源构成，从而形成面光源以确保发出的光线通过调光片材12均匀进入显示面板13，所述板材、调光片材12及显示面板13三者之间平行设置。其中：
显示面板13为传统意义上的液晶显示面板，如图2所示，显示面板13包括平行间隔设置的阵列基板（Thin Film Transistor，TFT基板或薄膜晶体管基板）131和彩膜基板（Color Filter，CF基板或彩色滤光片基板）132以及夹持于两者之间的液晶分子133。
调光片材12为一种PDLC（Polymer Dispersed Liquid Crystal，聚合物分散型液晶）片材，如图3所示，其包括平行间隔设置的第一基板121和第二基板122以及夹持于两者之间的液晶分子123和预聚物124。调光片材12实际可以表现为电控型调光玻璃板或液晶调光膜，在其为电控型调光玻璃板时，调光片材12可与显示面板13平行间隔设置，在其为液晶调光膜时，调光片材12可以贴附于显示面板13上。在本发明实施例中，至于调光片材12临近显示面板13的阵列基板131还是彩膜基板132，取决于光线经哪一个基板进入，具体地，若光线经阵列基板131进入显示面板13且由彩膜基板132出射，则调光片材12临近阵列基板131设置；若光线经彩膜基板132进入显示面板13且由阵列基板131出射，则调光片材12临近彩膜基板132设置。
调光片材12的制备方式包括但不限于：首先将液晶分子123与预聚物124混合，并填充到对盒的第一基板121和第二基板122之间形成液晶盒，然后使用光线照射填充有所述混合物的液晶盒，液晶盒中的混合物在光线的作用下发生聚合反应形成高分子聚合物，其中高分子聚合物在光线照射下形成空间骨架结构，并在骨架与骨架之间形成凹槽结构，当液晶分子123向凹槽结构运动时便形成了高分子分散体系，即微米级的液晶分子123均匀地分散在高分子网络中。在此基础上，利用液晶分子123的介电向异性即可控制液晶分子123在调光片材12中的排列方式，从而控制光线经调光片材12出射的角度。
背光源11可以为准直背光源，即只能发出垂直于调光片材12和显示面板13的光，结合图1所示，所述液晶显示器10在窄视角显示模式和宽视角显示模式之间进行切换的原理及过程如下：
在对调光片材12施加电压时，结合图4所示，
液晶分子123发生偏转并垂直于显示面板13的第一基板121和第二基板122以允许所述光通过，此时调光片材12呈现透明的外观，即为透明态，所述光经调光片材12出射后不会发生偏转仍旧垂直于调光片材12并入射至显示面板13。在显示面板13施加灰阶电压时，液晶分子133发生偏转以允许光线通过，出射的光仍旧垂直于显示面板13。可见，背光源11发出的光依次经调光片材12和显示面板13出射后并未发生偏转，此时只有沿垂直于显示面板13的方向观看才有良好的视角效果，即液晶显示器10为窄视角显示模式。
在未对调光片材12施加电压时，结合图5所示，
液晶分子123未发生偏转，液晶分子123呈现不规则的分布状态，即散射态，所述光经调光片材12会发生散射，经调光片材12出射的光与调光片材12具有夹角，并入射至显示面板13。在显示面板13施加灰阶电压时，液晶分子133发生偏转以允许光线通过，经显示面板13出射的光仍旧与显示面板13具有夹角，此时在多个方向观看显示面板13均可以有良好的视角效果，即液晶显示器10为宽视角显示模式。
在实现上述原理及过程时，显示面板13和调光片材12可以单独连接电源，也可以连接同一电源，即，用于控制夹持于阵列基板131和彩膜基板132之间的液晶分子133进行偏转的电源，还用于为夹持于第一基板121和第二基板122之间的液晶分子123施加电压。
本发明实施例还提供一种新型的液晶显示面板，即，将上述调光片材12与传统的显示面板13整合为一个组件，并用于液晶显示器中。
由上述可知，本发明只需在传统的显示面板的入光方向上增加一个调光片材，用以调节进入显示面板的光的角度，而后只要选择是否给调光片材施加电压，即可实现窄视角显示模式和宽视角显示模式的切换，以此满足用户在不同场合下的观看需求以保护用户隐私，进行两种显示模式切换的操作十分简单，且成本较低。
在此基础上，以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，例如各实施例之间技术特征的相互结合，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
