Description

多面显示器 技术领域

背景技术
随着显示器技术的迅速发展，作为显示设备的一种，液晶显示器已经成为平板显示领域的主流。LCD是通过两片导电玻璃形成的电场驱动其间的液晶来实现显示的，由于液晶本身并不发光，因此，LCD需要通过外部背光光源实现投射及反射显示。
目前，在很多场所（如篮球场馆、音乐厅、卖场等）都需要采用多台显示器来实现多面显示的功能，在这样的使用中，多个显示器同时工作需要消耗大量的能量，造成了能源的浪费。
因此，现在需要提供一种多面显示器，该多面显示器可以通过共用的能源进行工作，从而实现节约能源。然而，在现有的多面显示器中共用的背光光源只有一个发光体，从而使得液晶显示器因透射或反射的背光光源有限而导致其显示效果差。

具体实施方式
多面显示器可以用于篮球场馆、音乐厅等需要多个液晶显示器同时工作的场所，采用本发明提供的多面显示器可以有效地节约能源并且还能提供良好的显示效果。这种多面显示器还具有较高的结构强度和良好的稳定性，多面显示器中的多个液晶显示面板可靠地连接。
参考图1至图4，本发明实施例的多面显示器，包括分别面向多个方向的多个液晶显示面板100，多个液晶显示面板100围成容纳空间201，容纳空间201内设置有用于向多个液晶显示面板100提供背光的背光光源300。 背光光源300包括多个与所述多个液晶显示面板100分别对应的光源组件 （未标号） ，每个所述光源组件为对应的所述液晶显示面板100提供背光。
具体地，背光光源300包括上安装板301、下安装板303和多个发光体302。发光体302为可向四周发射光线的条状背光光源。上安装板301与下安装板303平行设置，多个发光体302垂直连接在上安装板301与下安装板303之间。这样的背光光源结构可以增强背光光源的结构强度。当然在其他的实施例中，也可以不设置上安装板301，仅设置下安装板303以承载多个发光体302。
为了使面向不同方向的每个液晶显示面板100获得均匀的光线，多个发光体302在下安装板303上排列成多个光源组件，每组光源组件与一个液晶显示面板100对应，且与该液晶显示面板100平行设置。每组光源组件与其对应的液晶显示面板100之间的距离相等，且每组光源组件含有相同个数的发光体302，这样当背光光源300开启时，每个液晶显示面板100均获得相同量的光量，这样保证每个液晶显示面板的显示效果均一。
在本实施例中，多面显示器还包括多个安装件200。每个液晶显示面板100容纳在一个安装件200中，多个液晶显示面板100通过多个安装件200依次首尾相连形成该容纳空间201。这样的连接方式可以增强多个液晶显示面板100之间的连接强度，提高多面显示器的整体结构强度。
具体地，在本实施例中，每个安装件200的横截面大致呈矩形，安装件202包括底壁202和沿底壁202的各个边缘向远离该底壁202的方向垂直延伸形成的多个侧壁（未标号）。该底壁202和多个侧壁围合成一安装槽（未标号）以安装液晶显示面板100。这样就可以形成简单的安装结构使该液晶显示面板100嵌合在该安装槽中并可拆卸地安装在该安装槽中。安装槽呈矩形，多个侧壁分为一对横侧壁204和一对竖侧壁205。
现有的液晶显示面板100一般包括液晶玻璃101、主电路板102以及连接在液晶玻璃101以及主电路板102之间的多个副电路板103，并且多个副电路板103是间隔设置的。现有的液晶显示面板100的外部轮廓复杂，为了使液晶显示面板100在安装槽中更稳定，所以安装槽需设计成与该液晶显示面板100的外部轮廓相适配的形状。因此，该安装件200还设置了多个条形平板状的隔断臂206。多个隔断臂206呈直线排列且间隔设置，每两个隔断臂206之间的间隔距离略大于每个副电路板 103的宽度。多个隔断臂206沿横向方向设置在安装槽中，即多个隔断臂206与一对横侧壁204相平行且连接在一对竖侧壁205之间。每个隔断臂206的内表面以胶粘的方式与底壁202相贴合。这样的多个隔断臂206就将安装槽分割成用于安装液晶玻璃101的第一安装槽210、用于安装主电路板102的第二安装槽220和用于安装多个副电路板103的多个第三安装槽230。第一安装槽210是由位于顶部的横侧壁204、一对竖侧壁205以及多个隔断臂206的上端围合而成。相应地，第二安装槽220是由位于底部的横侧壁204、一对竖侧壁205以及多个隔断臂206的下端围合而成。多个第三安装槽230间隔设置，间隔的距离与每个隔断臂206的长度相等。
为了防止每个液晶显示面板100的主电路板102受到污染或被水汽浸湿，则安装件200上还设置盖板209，该盖板209盖设在第二安装槽220上以防止安装在该第二安装槽220中的主电路板102外露。
为了使安装件200在结构简单并减少组装时间，所以将底壁202与多个侧壁采用挤压等方式一体成型。优选地是，底壁202、多个侧壁以及隔断臂206均采用挤压等方式一体成型。
为了使液晶显示面板100获取均匀分布的面背光光源，需要在液晶显示面板100靠近背光光源300的一侧上设置光学膜片以使背光光源300发出的光线分散以形成面背光光源。光学膜片包括扩散膜、导光板等。在本实施例中，将底壁202、多个侧壁均采用亚克力材料或PC材料制成，这样就可以将底壁202用作光学膜片。这样就可以减少光学膜片的组装，使多面显示器的整体结构简单。
下面举例说明本发明提供的第一实施例的多面显示器。
本发明实施例的多面显示器的第一实施例中，所述多面显示器为四面显示器，包括四个液晶显示面板100，每个液晶显示面板100安装在一个安装件200的安装槽中。四个液晶显示面板100通过4个安装件200依次首尾相连形成容纳空间201。容纳空间201的横截面呈方形。背光光源300安装在该容纳空间201内，背光光源300的上、下安装板301、303也呈方形。多个发光体302也排列成4组光源组件，每组光源组件与一个液晶显示面板100相平行。4组光源组件形成方形结构，与四个液晶显示面板100所组成的形状一致。每两个相邻的安装件200的两个相邻的竖侧壁205以胶粘、铆接、焊接等方式连接在一起。或者，也可以将4个安装件200一体成型呈方形的框架结构。在其他的实施例中，也可以是3个、5个或更多个液晶显示面板100的相互连接。
参考图5至图7，本发明提供的第二实施例的多面显示器。该多面显示器与第一实施例中多面显示器的区别在于：多个液晶显示面板之间的连接结构不同。在第二实施例中，每两个相邻的液晶显示面板100通过第一固定件400连接在一起，多个液晶显示面板100通过多个第一固定件400相互连接形成容纳空间201。通过这种连接方式连接而成的多面显示器具有拆装方便的优势。
第一固定件400呈条形，每个第一固定件400垂直连接在背光光源300的上、下安装板301、303的一对边缘之间。第一固定件400包括第一侧板401和与该第一侧板401垂直连接的第二侧板402。两者以焊接的方式固定连接，也可以理解为一平板折弯形成的两部分。
第一侧板401为条形平板。第一侧板401的中部位置沿其长度方向上开设有第一容纳槽403，该第一容纳槽403沿长度方向贯穿该第一侧板401的两端。在第一侧板401的外表面（靠近所述背光光源300的一侧为内表面）上沿其长度方向开设有第二容纳槽404，该第二容纳槽404与第一容纳槽403相平行。
第二侧板402也为条形平板。第二侧板402的中部位置沿其长度方向上也开设有该第一容纳槽403，该第一容纳槽403沿长度方向贯穿该第二侧板402的两端。在第二侧板402的外表面上沿其长度方向也开设有该第二容纳槽404。
该第一容纳槽403的横截面呈U型，能更好地放置待容纳的物体。第二容纳槽404的横截面呈L型，用于容纳待容纳的物体。该第二容纳槽404用于容纳液晶显示面板100。一个液晶显示面板100的一侧与第一固定件400的第一侧板401中的第二容纳槽404相抵持，该液晶显示面板100的另一侧抵持在与该第一固定件400相邻的另一个第一固定件400的第二容纳槽404上。同时，另一个液晶显示面板100的一侧与该第一固定件400的第二侧板402的第二容纳槽404相抵持。
为了使多个液晶显示面板100的连接更加稳固，本实施例中还提供了第二固定件500。在本实施例中，每个液晶显示面板100通过至少一个第二固定件500与背光光源300固定连接。具体地，该第二固定件500是由条形平板折弯成型，包括平板状的第一折弯部501和平板状的第二折弯部502。第一折弯部501与第二折弯部502相垂直以便与液晶显示面板100以及上安装板301或下安装板303相互之间更好地贴合。在其余的实施例中，两者也可以是呈一定夹角，夹角的角度小于90°。将第一折弯部501与液晶显示面板100以粘接的方式固定连接，第二折弯部502以粘接的方式固定连接到背光光源300的上安装板301或下安装板303上，或者提供2个第二固定件500将一个液晶显示器100的上下两端分别固定连接在上、下安装板301、303。这就实现了液晶显示面板100与背光光源300之间的固定连接。
为了使液晶显示面板100获取均匀分布的面背光光源，需要在每个液晶显示面板100靠近背光光源300的一侧上设置一个光学膜片600以使背光光源300发出的光线分散以形成面背光光源。光学膜片包括扩散膜、导光板等。在本实施例中，提供了与每个液晶显示面板100一一对应的光学膜片600。在组装该多面显示器时，将该光学膜片600的一侧插入一个第一固定件400的第一容纳槽403中，该光学膜片600的另一侧插入与该第一固定件400相邻的另一个第一固定件400的第一容纳槽403中。
为了使组装后的多面显示器更加美观，在每个液晶显示面板100与第二固定件500的连接处粘贴装饰条700以遮盖该连接处。
下面举例说明本发明提供的第二实施例的多面显示器。
本发明实施例的多面显示器的第一实施例中，所述多面显示器为四面显示器，包括四个液晶显示面板100和连接在每两个相邻的液晶显示面板100之间的4个第一固定件400。每个第一固定件400垂直连接在上安装板301与下安装板303的一对边缘之间。光学膜片600的两侧分别插置在相邻的两个第一固定件400的第一容纳槽403中，与光学膜片600一一对应的液晶显示面板100的两侧也分别与该相邻的两个第一固定件400的第二容纳槽404相抵持。提供8个第二固定件500，通过每2个第二固定件500分别将每个液晶显示面板100的上、下两端固定在背光光源300的上、下安装板301、303上。依次类推，该多面显示器也可以是3面、5面或更多面的显示器。
应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本发明所附权利要求的保护范围。
