Description

显示面板及液晶显示设备
本申请要求于2017年1月20日提交中国专利局、申请号为2017100426686、发明名称为“显示面板及液晶显示设备”的中国专利申请的优先权，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
本申请涉及液晶制造技术领域，尤其涉及一种显示面板及液晶显示设备。
背景技术
随着科技的发展和社会的进步，人们对于信息交流和传递等方面的依赖程度日益增加。薄膜晶体管液晶显示器(thin film transistor-liquid crystal display，TFT-LCD)作为信息交换和传递的主要载体和物质基础，现已成为众多从事信息光电研究科学家争相抢占的热点和高地。TFT-LCD的偏光部件很大程度上决定着TFT-LCD的关键特性指标，如穿透率，亮度，厚度等等。常见的偏光片使用碘系材料制成，偏光片包括起偏光作用的碘系偏光膜和贴合于偏光膜两侧表面的支撑保护膜，支撑保护膜起到保护偏光膜和固定偏光片平整的作用。
现有技术中，偏光片贴附在液晶盒的彩膜基板或阵列基板背离液晶层的表面，即液晶盒的外表面。当显示设备处于湿热等恶劣的工作环境时，支撑保护膜会发生翘曲，引起偏光片翘曲，甚至导致整个液晶盒弯曲，显示设备出现显示异常，或者偏光片翘曲后脱离液晶盒，导致显示设备显示异常。

请一并参阅图1和图2，本申请实施例一提供的显示面板包括第一基板10、第二基板20及位于第一基板10和第二基板20之间的液晶层40，具体的，第一基板10、第二基板20分别为彩膜基板和阵列基板中的一种。阵列基板阵列排布多个像素单元，每个像素单元包括一个像素电极和一个薄膜晶体管，阵列基板上还设有数据线和扫描线，并且数据线和扫描线相互垂直。进一步的，扫描线连接每一行的薄膜晶体管的栅极，用于控制薄膜晶体管的通断状态，即漏极与源极的连通状态，数据线连接每一列的薄膜晶体管的漏极，每一个像素电极连接薄膜晶体管的源极，数据线控制像素电极的电压，从而控制第一基板10与第二基板20之间的驱动电压，改变液晶层40内的液晶分子的偏转状态控制透过的背光的亮度。彩膜基板用于使背光源光线显示红、绿、蓝三基色，从而改变显示的图像的内容。第一基板10、第二基板20及液晶层40利用背光模组提供的背光 源各种彩色的图像。
本实施例中，显示面板还包括第一偏光膜50和第一框胶30，第一偏光膜50贴合于第一基板10之面对第二基板20的表面，第一框胶30连接于第一基板10和第二基板20之间，且与第一基板10和第二基板20共同形成封闭盒体，第一偏光膜50和液晶层40收容于封闭盒体内。进一步的，第一基板10包括一对第一端面102及连接一对第一端面102的边缘的第一侧壁面104，一种较佳的实施方式中，第一基板10为长方体形状，即一对第一端面102为尺寸相同的矩形，四个第一侧壁面104分别连接一对第一端面102的四对边；第二基板20包括一对第二端面202及连接一对第二端面202的边缘的第二侧壁面204，一种较佳的实施方式中，第二基板20为长方体形状，即一对第二端面202为尺寸相同的矩形，四个第二侧壁面204分别连接一对第二端面202的四对边。第一偏光膜50贴合于第一基板10之面对第二基板20一侧的第一端面102，具体的，粘贴第一基板10与第一偏光膜50的胶水为透明材料的胶水，以避免影响显示面板的透光率。第一框胶30连接于第一基板10和第二基板20之间，一种实施方式中，第一框胶30粘贴于第一侧壁面104和第二侧壁面204，其他实施方式中，第一框胶30也可以位于第一基板10和第二基板20之间，第一框胶30粘贴第一基板10面对第二基板20的第一端面102与第二基板20面对第一基板10的第二端面202。第一框胶30、第一基板10及第二基板20形成封闭的盒体，以使第一偏光膜50与显示面板之外界环境隔绝。一种实施方式中，第一框胶30为边缘胶，可以降低成本，其他实施方式中，第一框胶30也可以部分为边缘胶，以减少制程，节省产能。
第一偏光膜50粘贴于第一基板10上并位于第一基板10、第二基板20及第一框胶30相互粘连形成的封闭盒体内，将第一偏光膜50与外界环境隔离，避免了外界恶劣环境对偏光膜片的影响，提高了第一偏光膜50的结构稳定性，保持显示设备正常工作。再者，第一偏光膜50直接贴合在第一基板10使用，未使用两层支撑保护膜保护第一偏光膜50，减小了偏光片的厚度，有利于液晶显示设备的超薄化设计。
进一步的，第二基板20的背离第一基板10一侧的第二表面还贴合有第二偏光片55，第二偏光片55与第一偏光膜50的偏振方向垂直，背光模组发出的背光源光线穿过第一偏光膜50后，经过处于偏转状态的液晶分子改变偏振方向后穿 过第二偏光片55形成图像。具体的，第二偏光片55包括两片支撑保护膜及夹在两层支撑保护膜之间的偏光膜。

本实施例中，第二框胶60在第一基板10的投影位于第一偏光膜50的范围之内，并且液晶层40位于第一偏光膜50、第二框胶60及第二基板20形成的封闭空间内。进一步的，液晶层40内的液晶分子仅接触第一偏光膜50的表面、第二框胶60及第二基板20，第二框胶60限制了液晶分子分布的位置，是液晶分子无法与第一偏光膜50边缘的端面接触，有效的防止了液晶分子从偏光膜的端面接触偏光膜，避免了液晶分子与偏光膜相互污染甚至发生反应的情况发生，同时保证了液晶分子的寿命和第一偏光膜50的寿命。
请参阅图3，本申请实施例二提供的显示面板与实施例一的区别在于，显示面板还包括第二偏光膜52，第二偏光膜52贴合于第二基板20之面对第二基板20一侧的第二端面202，并且显示面板不包括第二偏光片55。第二偏光膜52与第二偏光片55相比去除了两片支撑保护膜，一般偏光片的厚度约200μm，两片支撑保护膜的厚度和约为50μm，即第二偏光膜52相比第二偏光片55的厚度减少了约25％，有利于液晶显示设备的超薄设计。再者，第一偏光膜50粘贴于第一基板10上，第二偏光膜52粘贴于第二基板20上，并且第一偏光膜50和第二偏光膜52均位于第一基板10、第二基板20及第一框胶30相互粘连形成的封闭盒体内，将第一偏光膜50和第二偏光膜52与外界环境隔离，避免了外界恶劣环境 对偏光膜片的影响，提高了第一偏光膜50和第二偏光膜52的结构稳定性，保持显示设备正常工作。

本实施例中，第二框胶60在第一基板10的投影位于第一偏光膜50的范围之内，并且液晶层40位于第一偏光膜50、第二框胶60及第二偏光膜52形成的封闭空间内。进一步的，液晶层40内的液晶分子仅接触第一偏光膜50的表面、第二框胶60及第二偏光膜52的表面，第二框胶60限制了液晶分子分布的位置，是液晶分子无法与第一偏光膜50边缘的端面及第二偏光膜52边缘的端面接触，有效的防止了液晶分子从偏光膜的端面接触偏光膜，避免了液晶分子与偏光膜相互污染甚至发生反应的情况发生，同时保证了液晶分子的寿命、第一偏光膜50及第二偏光膜52的寿命。
本申请实施例提供的第二框胶60内混有纤维，以增加第二框胶60的厚度，满足与第一偏光膜50和第二偏光膜52形成封闭结构的要求，隔离液晶层40与第一偏光膜50的端面及第二偏光膜52的端面，并增强第二框胶60的强度，以起到支撑第一基板10与第二基板20的作用。
进一步，本申请实施例提供的第一偏光膜50和第二偏光膜52均为染料系偏光膜。染料系偏光片具有优异的耐湿性和耐热性，可以很好适应恶劣的工作环 境。
请参阅图4，本申请实施例三提供的显示面板与实施例一的区别在于，第一框胶30包括主体部分302及设于主体部分302上的凸起部分304，凸起部分304粘贴于第一基板10与第二基板20之间，即凸起部分304粘贴第一基板10面对第二基板20的第一端面102与第二基板20面对第一基板10的第二端面202；主体部分粘贴第一侧壁面104和第二侧壁面204。凸起部分304粘贴第一端面102和第二端面202，主体部分302粘贴第一侧壁面104和第二侧壁面204，从而增强了第一框胶30、第一基板10及第二基板20形成的封闭盒体密封性能，提升了第一偏光膜50与显示面板之外界环境隔绝效果，避免了外界恶劣环境对第一偏光膜50的影响，提高了第一偏光膜50的结构稳定性，保持显示设备正常工作。

请参阅图6，本申请实施例二提供的液晶显示设备，本实施例与实施例一的区别在于，使用第一基板10作为背光模组的导光板702将从第一侧壁面104射入的背光源光线导向第二基板20方向。实施例二提供的显示设备节约了一个导光板702的厚度，更有利于液晶显示设备向超薄方向发展。
第一偏光膜50粘贴于第一基板10上并位于第一基板10、第二基板20及第一框胶30相互粘连形成的封闭盒体内，将第一偏光膜50与外界环境隔离，避免了外界恶劣环境对偏光膜片的影响，提高了第一偏光膜50的结构稳定性，保持显示设备正常工作。再者，第一偏光膜50直接贴合在第一基板10使用，未使用两 层支撑保护膜保护第一偏光膜50，减小了偏光片的厚度，有利于液晶显示设备的超薄化设计。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易的想到各种等效的修改或替换，这些修改或替换都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
