Abstract

本发明涉及一种显示设备及其安装。

Description

显示设备及其安装
技术领域
本发明涉及一种显示设备及其安装。
背景技术
从现有技术中已知如何通过螺钉（screw boss）/定位销组合的形式的定位元件将TFT(薄膜晶体管)显示器关于承载部件定位以及通过螺钉紧固将其固定至承载部件。随后安装到承载部件的前盖然后必须定位至距离TFT显示器一定距离，以便补偿TFT显示器的厚度公差(大约0.3mm)并且防止压力施加到TFT显示器的前部。该关键的间距最终导致在视差方面的困难，因为尽管在显示器上没有像素将被遮住，但在同一时间不能从所有观测角度看到显示器的帧。
发明内容
本发明解决的问题在于提出一种显示设备及其安装，其中显示单元无需被加载前向压力，并能克服现有技术的前述缺点。
该问题通过具有显示器和前面部分的显示设备解决，其中在前面部分和显示器之间设置中间部分，并且该中间部分以摩擦接合的方式连接至显示器。
本发明涉及一种显示器。该显示器可以是本领域的技术人员熟知的任何显示器，例如TFT、LCD和/或OLED显示器。
此外，根据本发明的显示器具有前面部分，其中在前面部分和显示器之间设置中间部分，该中间部分可以首先用于将显示器预固定至前面部分，和/或将前面部分连接到显示器。
根据本发明可以预知所述中间部分以摩擦接合的方式连接到显示器。优选地通过将至少部分的所述中间部分压在显示器上来产生所述摩擦接合。
所述中间部分因此优选为框状的中间件，特别地，其优选为由弹性材料制造，如橡胶材料和/或泡沫材料。在显示设备的装配过程中，该中间部分优选地弹性变形，从而至少部分地朝向显示器按压，其产生摩擦接合。此外，弹性中间部分具有容许精度相对粗糙的制造公差的优点。在优选的实施方式中，中间部分也用作密封件，以防止污物和/或湿气渗入根据本发明的显示设备。
所述中间部分优选地具有至少一个凹进部，设置于所述承载部件的扩宽装置（splaying means）以扩宽的方式与所述凹进部接合。所述扩宽装置，特别是其截面，优选地在尺寸上比至少部分的凹进部的截面更大。所述扩宽装置因此使凹进部扩宽或变宽。所述扩宽装置从承载部件到扩宽装置的梢端逐渐变细。所述扩宽装置特别优选设置成楔形。该扩宽装置使中间部分产生弹性变形。所述中间部分优选地被夹在承载部件和前面部分之间。所述中间部分优选地具有多个凹进部，为与之配合扩宽装置布置于承载部件上。所述各凹进部优选地关于中心轴线对称设置。
在优选的实施方式中，所述显示设备具有前部玻璃。
所述前部玻璃优选地连接到显示器，特别是以物质结合的方式。光学粘接剂尤其适合于该粘接结合。
所述显示设备的前面部分优选地设置有盖。前部玻璃优选地布置在该盖上。
本发明的又一个目的在于提供一种安装根据本发明的显示设备的方法，其中显示器置于所述前面部分并且以摩擦接合的方式连接至所述中间部分。
对有关根据本发明的显示设备的评述同样适用于根据本发明的所述方法，反之亦然。
所述中间部分优选地由承载部件至少部分地变形。此外，所述承载部件优选地连接至所述前面部分。特别地，该相互连接通过螺纹闭合件或卡扣配合，特别优选以无工具的方式实现。所述扩宽元件在这种情况下可以用作限制装置，以便使所述中间部分不会过于变形。
因此，本发明的一个方面特别涉及布置于在两个第一组件之间形成的中间空间内的中间部分，所述中间部分保证了例如在两个第一组件之间相对于彼此的预定位。所述中间部分的至少一个区域是由弹性变形材料形成，而另一第二组件设置有至少一个相对尺寸稳定的压配合工具。当各个组件装配成作为显示设备的单元时，弹性变形区域通过压配合工具变形，从而压在所述第一组件中的一个的表面上。
附图说明
以下将借助图1~3描述本发明。这些描述仅为示例的方式，并不限制本发明的基本思想。该描述同样适用于本发明的两个目的。
附图中：
图1示出了根据本发明的显示设备的分解视图；
图2示出了图1的显示设备在显示设备的装配中的较早阶段的细节截面图；
图3示出了图2在显示设备的装配中的较晚阶段的图示。
以下附图中，相同的组件和元件设有相同的附图标记。
具体实施方式
图1的分解视图所示的根据本发明的显示设备1布置在例如车辆驾驶舱中。显示设备1被前面部分2界定在前部，所述前面部分2包括具有一体的前部玻璃4的前盖3。由弹性变形材料（例如橡胶、硅树脂、热塑性弹性体和/或泡沫）制成的中间部分5具有框状的几何构造。显示设备1还包括显示器，在该示例中为TFT显示器6。
在中间部分5的前表面50（在安装状态下面朝前）上，开口7（只有其中一些分配有附图标记）向空间内张开。所述开口7在所述前表面50的整个周边上彼此以一定的间隔布置，其中也可采用另一布置。
承载部件8设置在显示器6后面，所述承载部件8具有扁平板状的基座主体80，其在后面约束住显示设备1。所述基座主体80在边缘上设置有与开口7对准的压配合楔9(只有其中一些分配有附图标记)。所述压配合楔9围绕基座主体80的整个周缘分布。
当各个组件被组装成最终的显示设备1时，所述显示器6首先从后侧被放入或布置于所述前面部分2内，以便使它抵靠前面部分2紧密配合（即至少事实上无间隙）。为预定位之目的，将中间部分5***或布置在显示器6和前盖2之间形成的所述中间空间，特别是显示器6的外周和前面部分的内周之间的中间空间中。在显示设备组装的进一步过程中，承载部件8随后与前面部分2或中间部分5会合。这一会合在示出了图1的显示设备1的细节的图2中由第一箭头P1所指示。
所述压配合楔9与开口7对准，从而在承载部件8与前面部分2会合期间，压配合楔9每个都与中间部分5的至少一个开口7接合。
由于压配合楔9的扩宽的楔形形状，随着承载部件8与前面部分2会合的进程，中间部分5在围绕开口7的有关区域内弹性形变逐渐增大从而移位，并且中间部分5的内周至少部分地抵靠挤压显示器6的表面（特别是抵靠其外周）。
图3示出了在显示设备的装配中相比图2处于较晚阶段的图2的图示。所述压配合楔9已经深入穿入了所述开口7。
材料变形的方向由第二箭头P2指示，该材料变形的方向同时表示将材料移位至显示器6的接触力的方向。
当压配合楔9已经达到其被限定的最终位置时，它们最终使显示器6填塞于前盖2内，并因此使显示器6通过摩擦力固定。前盖3然后通过螺钉10固定于或夹在承载部件8上。
各个开口/压配合楔组合彼此配合，特别地，在不同点的变形同时产生，这意味着实现了显示器6的对称定位。
也可以将前部玻璃安装至显示器（例如通过用光学粘合剂粘接等），然后布置所得到的包括显示器和前部玻璃的复合组件，以便使前部玻璃布置成与前盖的前侧齐平。同样在这种情况下，根据前述的原理通过位于前盖和显示器之间的中间部分的弹性变形来完成固定。
其结果是，示出了定位及固定显示器的新的方式，该方式中使显示器相对于前盖齐平。
对于根据本发明的显示器的定位和固定，可以省却位于TFT后侧的螺钉和销。
中间部分5可以设计成使它还具有密封件的功能，以防止外界的污垢渗入显示设备1的内部区域。
尽管以TFT显示器的示例对本发明进行了描述，这不应被视为限制性的。相反，本发明不仅仅用于TFT显示器，还可用于另一类型的显示器，例如发光或等离子显示器、LCD（液晶显示器）、OLED（有机发光二级管）等。
