相关申请的交叉引用
本公开要求于2022年10月13日提交的申请号为202211255746.8，名称为“裸眼3D显示装置、车辆”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及汽车技术领域，具体涉及一种裸眼3D显示装置、车辆。
背景技术
相关技术中，车载裸眼3D技术主要为光栅式，其中，固定光栅式，是通过BM(BlackMatrix,黑矩阵)光栅形成光学屏障，来控制光线行进方向，让观看者的其中一眼只能看到液晶面板奇数画面，观看者另一眼则只能看到液晶面板偶数画面，大脑融合后可产生3D效果；活动光栅式，形成光学屏障的材料变为透明ITO(Indium Tin Oxide，氧化铟锡)，通过交错位置加电使得该位置实现黑色，从而实现光栅效果，来控制光线行进方向，让左右两眼接受不同影响，大脑融合后可产生3D效果，并且通过增加摄像头，追踪眼球位置，通过算法控制不同位置ITO光栅的开启，实现广视角裸眼3D。
虽然光栅式的工艺较为成熟，但存在以下问题：
1)视角窄，光栅式最佳视角一般±20°内；
2)存在眩晕感，由于光栅式为视差屏障式，通过将图像区分为左右眼，达到3D效果，这样会使得大脑产生错觉，并且频繁对焦引起视觉疲劳，很容易使得观看者产生眩晕感。

下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述本公开实施例的裸眼3D显示装置、车辆。
图1是本公开一个实施例的裸眼3D显示装置的结构示意图。
如图1所示，裸眼3D显示装置100包括：半透半反膜10、仪表屏20和投影光机30。
具体地，半透半反膜10位于车辆的仪表屏20上，且与仪表屏20之间间隔第一预设距离，投影光机30用于将预设车辆信息投影在半透半反膜10上。仪表屏20显示除预设车辆信息之外的其他仪表信息，为正常2D显示。由此，可以通过半透半反膜10与仪表屏20之间间隔第一预设距离，形成空间上的纵深结构，实现了真实的3D显示，且由于不是双眼视差原理，不区分左右眼图像，因此不存在视角限制，可实现全视角，不存在眩晕感。
在本公开的一些实施例中，预设车辆信息包括导航箭头图标、车速、限速中的至少一者。
在本公开的一些实施例中，半透半反膜10通过光学胶粘贴在仪表屏20上，半透半反膜10与仪表屏20之间的光学胶厚度为上述的第一预设距离，并且第一预设距离为3～10mm。
作为一个示例，参照图2，在半透半反膜10和仪表屏20之间隔有光学胶40，该光学胶40为OCA(Optically Clear Adhesive，光学透明粘合剂)，厚度为第一预设距离，由此，该光学胶40使得半透半反膜10和仪表屏20不在一个层面上，并且设置该光学胶40厚度为第一预设距离，使其形成空间上的纵深结构，从而实现了真实的裸眼3D显示效果，不存在眩晕感，并且光学胶40具有无色透明、光透过率在90％以上、胶结强度良好的特点。
在本公开的一些实施例中，投影光机30位于车辆的主驾座椅靠背的斜上侧，可参照图3。
在本公开的一些实施例中，投影光机30采用发光二极管作为光源进行投影，投影光机30采用驱动薄膜晶体管液晶显示器，投影光机30也可采用数字光处理投影机或硅基液晶投影机，具体如下：

需要说明的是，上述车速31、限速32和导航箭头图标33的投影位置不局限于图4所示的垂直位置，参照图5，也可将车速31、限速32和导航箭头图标33投影为水平位置，最终的仪表屏显示效果图可参照图6。
另外，针对仪表屏20的选择，本公开还提出另外两种实施例，具体如下：
实施例一、仪表屏20使用异型柔性弯折屏，该弯折为凹型弯折，参照图7，仪表屏20的左右长度比例可根据实际情况进行具体设置，举例而言，该比例可以为1:1、1:2、1:3等。其中，左侧部分使用投影光机30投影车速31、限速32和导航箭头图标33至半透半反膜10上，实现裸眼3D效果，右侧部分则为仪表屏正常显示区，用来显示仪表屏的其他信息，实现正常的2D效果。
实施例二、采用中控屏，该中控屏为凸型弯折屏，参照图8，左右长度比例可根据实际情况进行具体设置，举例而言，该比例可以为1:1、1:2、1:3、2:3。其中，左侧部分作为仪表正常显示区，投影光机可将车速31、限速32、导航箭头33投影在左侧部分，实现裸眼3D效果，右侧部分作为中控屏显示区，实现正常的2D效果。
综上，本公开实施例的裸眼3D显示装置，包括：半透半反膜，半透半反膜位于车辆的仪表屏上，且与仪表屏之间间隔第一预设距离；投影光机，用于将预设车辆信息投影在半透半反膜上。由此，该裸眼3D显示装置，通过在半透半反膜与仪表屏之间设置第一预设距离，由投影光机将预设车辆信息投影在半透半反膜上，从而实现了真实的裸眼3D显示效果且无需区分左右眼视差，解决了眩晕感与视角窄的问题。

在本公开中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
尽管上面已经示出和描述了本公开的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本公开的限制，本领域的普通技术人员在本公开的范围内可以对上述实施例进行变化、修改、替换和变型。
