Description

一种液晶显示装置 技术领域
本发明涉及显示技术领域,特别涉及一种液晶显示装置。
背景技术
随着手机等电子设备的普及、电子设备中显示模组工艺技术的提升、以及电子设备中显示屏幕尺寸的增大,通过电子设备的窄边框设计来追求屏占比以及提升整机的紧凑度已成为提升产品竞争力的一个新的创新方向。
现有技术中,用于实现电子设备窄边框设计的手段有多种,如:
如图1a和图1b所示,在实现方式一中,将保护玻璃111与液晶显示面板112贴合后,在液晶显示面板112和背光模组113的侧壁涂密封剂115,形成如图1a所示的结构,然后采用激光切割工艺切除部分保护玻璃111和部分密封剂115,形成如图1b中所示的窄边框结构,再将液晶显示装置的壳体与液晶显示面板112和背光模组113粘合,形成液晶显示装置。
上述实现方式中,由于需在液晶显示面板112和背光源113的侧壁进行点胶,用于填充密封剂115的区域较深,导致点胶量较大且不容易控制、并需多次补胶擦拭,点胶工作的效率较低;为避免密封剂115渗入背光源113而导致降低显示效果,背光源113的周边需设置保护框114以避免密封剂115渗入,与常规背光源产品相比其结构较为复杂,增加了显示装置的制造成本。另外,因该实现方式中需对保护玻璃111和密封剂115进行激光切割工艺,增加了产品的制造成本,且使产品的生产效率进一步降低。
如图2所示,在实现方式二中,保护玻璃121的边角为弧面,通过弧面的折射以产生窄边框的视觉效果。该实现方式中,需在保护玻璃121和显示模组122的侧面涂密封剂123,以将壳体124与保护玻璃121和显示模组122粘合,形成液晶显示装置。
上述实现方式中,由于需在背光模组122的侧壁进行点胶,用于填充密封剂123的区域较深,导致点胶量较大且不容易控制、并需多次补胶擦拭,点胶工作的效率较低;同时由于显示模组122的侧面直接与密封剂123接触,密封剂123易渗入显示模组122的背光源中,降低显示效果,影响良率。另外,该实现方式为实现窄边框效果,需增加保护玻璃121的厚度,增大了液晶显示装置的厚度和整体重量。
综上所述,以上两种常见的窄边框设计实现方式中,均因点胶深度较深和点胶量较大而降低了液晶显示装置的生产效率和良品率。
因此,如何避免因点胶深度较深和点胶量较大而降低液晶显示装置的生产效率和良品率是本领域技术人员亟需解决的技术问题之一。
发明内容
本发明提供了一种液晶显示装置,可减少点胶深度和点胶量,提高点胶效率;并降低了密封剂渗入背光源的概率,提高了产品的良品率。
第一方面,提供一种液晶显示装置,包括形成显示模组容置腔的壳体和设置于所述显示模组容置腔的显示模组,所述显示模组包括由所述显示模组容置腔的底面朝向开口方向依次排列的背光源组件、显示组件和防护玻璃,所述显示组件具有层级结构;其中,所述显示模组容置腔的侧壁上形成朝向所述显示模组容置腔开口的环形搭接面,所述显示组件的各层级结构中的至少一层形成凸向所述显示模组容置腔侧壁的搭接层或者所述保护玻璃形成凸向所述显示模组容置腔侧壁的搭接层,所述搭接层背离所述显示模组容置腔开口的侧面与所述搭接面搭接,且将所述显示模组容置腔的侧壁与显示模组之间的间隙分隔为两部分,且所述间隙位于所述搭接层朝向所述显示模组容置腔的开口一侧的部分填充有用于将所述显示模组与所述壳体粘结的密封剂。
结合上述第一方面,在第一种可能的实现方式中,所述显示模组容置腔具有阶梯槽结构,且所述阶梯槽结构的阶梯面形成所述搭接面。
结合上述第一方面,在第二种可能的实现方式中,所述显示模组容置腔的侧壁具有一凸向所述显示模组容置腔的环形凸台,所述环形凸台朝向所述显示模组容置腔开口一侧的台面形成所述搭接面。
结合上述第一方面,在第三种可能的实现方式中,所述搭接层与所述搭接面之间通过密封剂粘结。
结合上述第一方面、第一种可能的实现方式、第二种可能的实现方式、第三种可能的实现方式,在第四种可能的实现方式中,所述搭接层由所述显示组件中的非玻璃材质制成的层级结构形成。
结合上述第一方面、第一种可能的实现方式、第二种可能的实现方式、第三种可能的实现方式、第四种可能的实现方式,在第五种可能的实现方式中,所述搭接层由所述显示组件中显示面板出光侧设置的上偏光片形成。
结合上述第一方面、第一种可能的实现方式、第二种可能的实现方式、第三种可能的实现方式、第四种可能的实现方式、第五种可能的实现方式,在第六种可能的实现方式中,所述上偏光片与所述保护玻璃之间通过透明胶粘接。
结合上述第一方面、第一种可能的实现方式、第一方面的第二种可能的实现方式、第一方面的第三种可能的实现方式,在第七种可能的实现方式中,所述保护玻璃上形成有所 述搭接层。
结合上述第一方面、第一种可能的实现方式、第二种可能的实现方式、第三种可能的实现方式、第四种可能的实现方式、第五种可能的实现方式、第六种可能的实现方式、第七种可能的实现方式,在第八种可能的实现方式中,所述保护玻璃的侧面上形成有绕所述保护玻璃一周、且凸向所述显示模组容置腔侧壁的环形凸起,所述环形凸起形成所述搭接层。
结合上述第一方面、第一种可能的实现方式、第二种可能的实现方式、第三种可能的实现方式、第四种可能的实现方式、第五种可能的实现方式、第六种可能的实现方式、第七种可能的实现方式、第八种可能的实现方式,在第九种可能的实现方式中,所述环形凸起朝向所述搭接面的侧面与所述保护玻璃朝向所述显示模组容置腔底面的侧面平齐。
上述第一方面提供的液晶显示装置中,壳体上形成的搭接面与显示组件或保护玻璃上形成的搭接层相搭接,并将显示模组容置腔的侧壁与显示模组之间的间隙分隔为两部分,位于搭接层朝向显示模组容置腔的开口一侧的间隙形成用于填充密封剂的点胶区域,显示模组的侧面只有在点胶区域内与密封剂相接触,因此该液晶显示装置的点胶深度较浅,从而减少了点胶量,使点胶过程易于控制,进而提高了点胶过程的工作效率;同时因搭接面与搭接层将显示模组中的背光源组件隔开,点胶区域的密封剂不与背光源组件接触,降低了密封剂渗入背光源组件中的概率,因此,提高了显示装置的良品率。
附图说明
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。

图6为本发明一种实施例提供的液晶显示装置的部分结构示意图。
具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动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。
请参考图3、图4、图5和图6,图3为本发明一种实施例提供的液晶显示装置的结构示意图;图4为本发明一种实施例提供的液晶显示装置的部分结构示意图;图5为本发明一种实施例提供的液晶显示装置的部分结构示意图;图6为本发明一种实施例提供的液晶显示装置的部分结构示意图。
如图3、图4、图5和图6所示,本发明实施例提供了一种液晶显示装置,包括形成显示模组容置腔241的壳体240和设置于显示模组容置腔241的显示模组220,显示模组220包括由显示模组容置腔241的底面朝向开口方向依次排列的背光源组件223、显示组件222和防护玻璃221,显示组件222具有层级结构;其中,显示模组容置腔241的侧壁上形成朝向显示模组容置腔241开口的环形搭接面242,显示组件222的各层级结构以及保护玻璃中221的至少一层形成凸向显示模组容置腔241侧壁的搭接层224,搭接层224背离显示模组容置腔241开口的侧面与搭接面242搭接,且将显示模组容置腔241的侧壁与显示模组220之间的间隙分隔为两部分,且间隙位于搭接层朝向显示模组容置腔241的开口一侧的部分填充有密封剂230,以将显示模组220与壳体240粘结。
上述液晶显示装置中,壳体240上形成的搭接面242与显示组件222或保护玻璃221上形成的搭接层224相搭接,并将显示模组容置腔241的侧壁与显示模组220之间的间隙分隔为两部分,位于搭接层224朝向显示模组容置腔241的开口一侧的间隙形成用于填充密封剂230的点胶区域,显示模组220的侧面只有在点胶区域内与密封剂230相接触,因此该液晶显示装置的点胶深度较浅,从而减少了点胶量,使点胶过程易于控制,进而提高了点胶过程的工作效率;同时因搭接面242与搭接层224将显示模组220中的背光源组件223与点胶区域隔开,点胶区域的密封剂230不与背光源组件223接触,降低了密封剂230渗入背光源组件223中的概率,从而提高了显示装置的良品率。
一种优选实施方式中,如图3所示,显示模组容置腔具有阶梯槽结构,且阶梯槽结构的阶梯面形成搭接面242。
此外,为进一步降低密封剂230渗入背光源组件223所在区域的概率,如图4和图5所示,显示模组容置腔还具有凹槽结构243,凹槽结构243的开口朝向显示模组容置腔,可用于容纳密封剂230,减少密封剂230从此处渗出的概率,且增大了密封剂230与壳体240之间的接触面积,因此提高了密封剂230的粘着牢固度。
参见图6所示,一种优选实施方式中,显示模组容置腔的侧壁具有一环形凸台244,环形凸台244凸向显示模组容置腔,且其朝向显示模组容置腔开口一侧的台面形成搭接面 242。
一种优选实施方式中,为增加搭接层与搭接面之间的密封性和连接牢固性,搭接层与搭接面之间通过密封剂粘结。
具体地,上述搭接层可由如下所述方式实现:
方式一:上述搭接层可由显示组件中的层级结构形成。
具体地,上述搭接层可由显示组件中的的非玻璃材质制成的层级结构、或玻璃材质制成的层级结构形成,优选地,为保证搭接层的使用强度,可优先选用显示组件中的非玻璃材质制成的层级结构形成搭接层,可减少搭接层因受外力冲击或振动而造成损坏的概率。
优选地,如图3所示,搭接层224由显示组件222中显示面板出光侧设置的上偏光片2221形成。
优选地,为提高上偏光片2221与保护玻璃221之间的结合强度,如图3所示,上偏光片2221与保护玻璃221之间通过透明胶225粘接。
方式二:如图4所示,保护玻璃221的侧面上形成有绕保护玻璃221一周、且凸向显示模组容置腔241侧壁的环形凸起2211,环形凸起2211形成搭接层224。
优选地,环形凸起朝向搭接面的侧面与保护玻璃朝向显示模组容置腔底面的侧面平齐。
方式三:如图5所示,上述搭接层还可由保护玻璃221的周边形成,即保护玻璃221的周边搭接于搭接面242上。
显然,本领域的技术人员可以对本发明实施例进行各种改动和变型而不脱离本发明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
