Description

光学模组及头戴式显示设备
技术领域
[0001] 本发明涉及显示设备领域, 尤其涉及一种光学模组及头戴式显示设备。
背景技术
[0002] 随着科技的发展以及人们对多媒体视讯需求日渐增加, 常用的多媒体播放设备 需搭配外置的 LED或 LCD显示屏使用, 由于外置显示屏中显示影像的像素及大小 受限于显示器尺寸大小且视觉效果不能满足人们的需求, 头戴式显示器应运而 生。 头戴式显示器 (Head-Mounted Display , 简称 HMD) , 是一种立体视觉显示 的光学产品, 是将具有两眼视差的三维效果的信号, 依序透过设置于双眼前方 的显示元件以及光学镜头传送至双眼, 进而产生立体而大尺寸的影像。 头戴式 显示设备通常是应用在增强现实 (augmented reality ,AR)***或虚拟现实 (virtual reality ,VR)***, 并可跟着用户移动以及当作一种输入设备来接收用户的反应, 且透过戴在用户头部的头戴式显示设备, 将图像和文件加到用户所观看的影像 上, 进而达到增强现实或虚拟现实的效果。
[0003] 现有头戴式显示设备包括用于显示光学影像的头显模组和与所述头显模组相连 的用于佩戴在用户头部的佩戴头带模组, 头显模组内设有光学模组。 现有光学 模组包括显示屏、 设置在显示屏前方的左镜筒组件和右镜筒组件、 用于实现对 视距调节的视距调节组件和用于实现对瞳距调节的瞳距调节机构。 现有视距调 节组件通过同步移动左镜筒组件和右镜筒组件前后移动以实现视距调节; 瞳距 调节机构通过同步移动左镜筒组件和右镜筒组件左右移动以实现瞳距调节。 现 有的视距调节组件只能同步调节左镜筒组件和右镜筒组件的视距, 对左眼屈光 度与右眼屈光度不同的用户而言, 同步调节左镜筒组件和右镜筒组件的视距, 会导致用户通过光学模组观看影像吋, 左眼和右眼看到的影像的清晰度不同, 影响视觉体验。 而且现有瞳距调节机构在进行瞳距调节过程中, 使得左镜筒组 件和右镜筒组件相对于显示屏的有效显示画面发生相对移动, 导致左镜筒组件 和右镜筒组件的光学中心与显示屏的显示中心发生变化, 影响左镜筒组件和右 镜筒组件显示影像的显示效果。 而且现有瞳距调节机构也只能同步调节左镜筒 组件和右镜筒组件之间的距离, 无法根据佩戴者双眼瞳距状态单独调节左镜筒 组件和右镜筒组件位置。
技术问题
[0004] 本发明要解决的技术问题在于, 针对现有光学模组中视距调节机构和瞳距调节 机构只能同步调节左镜筒组件和右镜筒组件, 且瞳距调节机构调节瞳距里影响 影像效果的不足, 提供一种光学模组及头戴式显示设备。
