Description

数字驾驶舱显示器
技术领域
本发明涉及一种用于车辆的数字驾驶舱显示器，该数字驾驶舱显示器包括：具有多个电子显示元件的显示设备，这些电子显示元件以矩阵形式布置并且借助于这些电子显示元件可以使信息可视化；以及控制装置，借助于该控制装置可以控制用于使信息可视化的显示元件。
背景技术
在车辆内部空间的设计中，为驾驶员显示例如当前的车辆速度、机动车辆的驱动设备的转速和其他信息的常见的模拟圆形仪表直到几年前逐渐被数字驾驶舱显示器取代。这些数字驾驶舱显示器包括：具有多个以矩阵形式布置的电子显示元件的显示设备，借助于这些电子显示元件可以使对应的信息可视化；以及控制装置，借助于该控制装置可以控制用于使信息可视化的显示元件。这种数字驾驶舱显示器具有以下优点：这些数字驾驶舱显示器是可配置的并且因此可以使所展示的信息的范围以及信息再现的视觉外观适配于驾驶员的个人需求。在此，借助于数字驾驶舱显示器所显示的信息可以非常清晰地被展示。
尽管有色彩的显示效果，但这种驾驶舱显示器不具有任何三维深度效果，该三维深度效果例如是从模拟圆形仪表已知的。为了弥补这个问题，一些车辆制造商在特定的车型系列中已经提供了数字驾驶舱显示器，其中在显示设备上的可见区域中布置有固定的三维元件，这些三维元件提供对于观察者而言可见的三维深度效果。这种数字驾驶舱显示器同样可被配置成使得可以使例如所展示的信息的范围以及信息再现的视觉外观适配于驾驶员的个人需求。在此，借助于数字驾驶舱显示器所显示的信息同样可以非常清晰地被展示。然而，三维元件的位置固定的布置具有以下缺点：针对改变这种数字驾驶舱显示器的视觉外观的设计自由度受到相对严格的限制，原因在于这些三维元件在设计方面构成了用于信息展示的不可改变的区域。
DE 10 2017 209 268 A1公开了一种显示系统，该显示系统具有多个显示段以及一个面型的、弹性实施的显示载架。弹性的显示载架可以被施加力并且因此变形，使得至少两个显示段的相对位置可以改变。
发明内容
本发明的目的在于，提供一种开篇所述类型的数字驾驶舱显示器，该数字驾驶舱显示器可以以简单的方式实现产生三维效果的深度效果。
该目的的解决方案提供一种本发明所述特征的所属类型的数字驾驶舱显示器。其他说明涉及本发明的有利的改进方案。
根据本发明的数字驾驶舱显示器的特征之处在于：该显示设备具有多个微机电致动器，这些微机电致动器与这些显示元件连接并且这些微机电致动器可以由该控制装置以如下方式选择性地控制，使得这些微机电致动器实现这些显示元件在收缩位置和完全展开的位置之间的线性运动，在该收缩位置中这些微机电致动器的纵向伸展尺寸最小，在该完全展开的位置中这些微机电致动器的纵向伸展尺寸最大。除了借助于显示设备单纯地显示信息外，微机电致动器——通常也被称为微机电系统(缩写：MEMS)——可以实现选择性且可逆地产生三维深度效果，其方式为：对应的显示元件选择性地从收缩位置向完全或至少部分展开的位置运动并且因此朝向观察者运动。借助于上述技术，可以在数字驾驶舱显示器的显示设备上模拟例如常规圆形仪表的三维环形的边框。借助于显示设备可视化的信息例如可以包括当前的车辆速度、机动车辆的驱动设备的转速、当前的运行参数和/或环境参数、导航信息以及多媒体信息，其中原则上自然还可以显示其他的信息。优选地，显示设备以相对于所显示的信息和三维深度效果可配置的方式形成。因此，所展示的信息的范围和信息再现的视觉外观，尤其还鉴于三维深度效果，可以适配于驾驶员的个人需求。例如，微机电致动器也可以由控制装置以如下方式控制，使得显示元件中的至少一些显示元件的位置随时间变化，从而可以产生三维动画。
在一个有利的实施方式中提出：为多个显示元件相应地指配这些微机电致动器中的一个微机电致动器。换言之，在这个实施方式中，单个致动器可以实现多个显示元件同时的线性运动。
在一个替代的、特别优选的实施方式中存在以下可能性：为这些显示元件中的每个显示元件各自指配这些微机电致动器中的一个微机电致动器。因此在这个实施方式中，单独的致动器可以实现被指配给所涉及的致动器的单独的显示元件的线性运动。由此，可以产生具有非常高的局部分辨率的三维深度效果。
在一个有利的实施方式中提出：该显示设备具有保持面，这些微机电致动器是被安装在该保持面上的。在此，这个保持面尤其构成用于微机电致动器的线性运动的参考面，借助于这些微机电致动器可以使显示元件选择性地运动。
优选地，该保持面可以是由该显示设备的背面构成的。在这个实施方式中，显示设备的背面构成用于显示元件的线性运动的参考面。
在一个有利的实施方式中可以提出：这些显示元件形成为像素元件。
在一个特别有利的实施方式中提出：这些显示元件形成为多色的TFT像素元件。例如，显示元件可以形成为三色的RGB-TFT像素元件。
在一个优选的实施方式中存在以下可能性：能够以如下方式控制这些微机电致动器，使得这些显示元件中的至少一些显示元件选择性地向该收缩位置与该完全展开的位置之间的中间位置运动，在该收缩位置中这些微机电致动器的纵向伸展尺寸最小，在该完全展开的位置中这些微机电致动器的纵向伸展尺寸最大。对于所涉及的显示元件，中间位置可以是相同或至少部分不同的。因此以有利的方式使显示元件不仅可以从完全收缩的位置运动到完全展开的位置，而且还可以运动到这些位置之间的各种中间位置。由此也可以以有利的方式产生渐次的三维深度效果。
附图说明
本发明的其他的特征和优点借助于参考图1对优选实施例进行的如下描述变得清晰。
图1以示意性极大简化的形式示出用于车辆的数字驾驶舱显示器1的一部分。
具体实施方式
数字驾驶舱显示器1包括具有多个电子显示元件3a-3n的显示设备2，借助于这些电子显示元件可以使信息对车辆的驾驶员而言可视化。电子显示元件3a-3n以二维矩阵形式的结构布置，其中在图1中出于简化原因仅展示了总共有n个显示元件3a-3n的单个行。优选地，这些显示元件3a-3n可以涉及多色的像素元件，尤其涉及三色的TFT-RGB像素元件。
数字驾驶舱显示器1还具有控制装置4，借助于该控制装置可以以如下方式控制显示元件3a-3n，使得这些显示元件可以为驾驶员显示各种信息。这些信息例如可以包括当前的车辆速度、机动车辆的驱动设备的转速、当前的运行参数和/或环境参数、导航信息以及多媒体信息。这个列举自然不是穷尽的并且可以扩充任意其他视觉可展示的信息。
显示设备2具有保持面6，显示元件3a-3n是借助于微机电致动器5a-5n被安装在该保持面上的。这个保持面6尤其可以是显示设备2的背面。微机电致动器5a-5n同样由控制装置4控制并且以如下方式设计，使得这些微机电致动器实现显示元件3a-3n在收缩位置与完全展开的位置之间的线性运动，在该收缩位置中微机电致动器5a-5n的纵向伸展尺寸最小，在该完全展开的位置中微机电致动器5a-5n的纵向伸展尺寸最大。在此优选地，为显示元件3a-3n中的每个显示元件分别指配微机电致动器5a-5n中的一个微机电致动器，该微机电致动器可以启动所涉及的显示元件3a-3n的线性运动。由此可以产生具有高的局部分辨率的三维深度效果。然而，原理上还可设想以下实施方式，其中为多个显示元件3a-3n指配单个微机电致动器5a-5n，从而可以同时借助于所涉及的微机电致动器5a-5n使这些显示元件运动。由此可以减少微机电致动器5a-5n的数量。
如在图1中可以看出，由控制装置4选择性可控制的微机电致动器5a-5n可以实现产生三维深度效果，其方式为：显示元件3a-3n中的一些显示元件远离显示设备2的在某种程度上构成参考面的保持面6并且因此朝向观察者运动，与之相反，其他的显示元件3a-3n保持在其初始位置，在该初始位置中，所属的微机电致动器5a-5n在收缩位置具有其最小的纵向伸展尺寸。在根据图1的图示中，以附图标记3a-3e、3j、3k和3n标识的显示元件位于初始位置，在该初始位置中，未激活所属的微机电致动器5a-5e、5j、5k和5n。以附图标记3h、3l和3m标识的显示元件位于相对于保持面6最大可能伸出的位置。其余设有附图标记3f、3g和3i的显示元件分别位于初始位置与最大可能展开的位置之间的中间位置。通过显示元件3a-3n的不同的伸出位置可以以有利的方式产生渐次的三维深度效果。原理上还可设想以下实施方式，其中显示元件3a-3n仅可以选择性地占据初始位置和最大伸出位置。于是，虽然对所属的微机电致动器5a-5n的控制更简单，然而并不能实现产生渐次的三维深度效果。
借助于上述技术，可以在数字驾驶舱显示器1的显示设备2上模拟例如常规圆形仪表的三维环形的边框。
例如，微机电致动器5a-5n还可以由控制装置4以如下方式控制，使得显示元件3a-3n的位置随时间变化，从而可以产生三维动画。
