Description

一种近眼显示眼镜
技术领域
本发明涉及近眼显示终端技术领域。
背景技术
近眼显示技术已经广泛应用于教育、工业、医疗、游戏、娱乐、驾驶、军事等领域,包括虚拟现实(VR)、增强现实(AR)、混合现实(MR)等。由于AR和MR都要与现实环境互动,用户既要看到真实的外部世界,也要看到虚拟信息,成像系统不能挡在视线前方,所以AR和MR眼镜需要一定的透光性,一般使用投影显示技术。
但是透光性决定了使用过程中会有一部分现实世界光线透过屏幕,同时一部分虚拟图像的光透出屏幕,所以会导致显示对比度低,亮度低,色域低,显示不够真实自然,低亮度无法满足室外或强光环境下的应用,限制了近眼显示系统的应用场景。
为了缓解这个问题,一些AR/MR采用曲面镜片(birdbath)等光学设计来阻挡环境光射入,或采用染色镜片来提高光学模组的相对亮度,但这样会降低光学模组的透光率,导致看不清现实世界。所以开发高对比度投影显示技术对于AR/MR很有意义。
发明内容
本发明所要解决的技术问题是实现一种多显示技术协同工作的近眼显示系统,并具有显示性能良好,适应能力强的性能。
为了实现上述目的,本发明采用的技术方案为:一种近眼显示眼镜,眼镜框上固定有镜片,所述眼镜框的两侧连接眼镜腿的前端,每个所述眼镜腿的前端均设有光波导入射光栅,每个所述镜片表面或镜片内设有光波导出射光栅,所述眼镜腿内安装有朝向光波导入射光栅投影的显示器,所述光波导入射光栅将显示器投影的图像衍射至所在侧镜片内的光波导出射光栅上显示,每个所述镜片的外表面固定有透明显示屏。
所述显示器和透明显示屏显示相同的内容,所述显示器为主显示设备用于显示图像,所述透明显示屏为副显示设备用于对比度、亮度和色域调节。
所述眼镜框或眼镜腿上固定有播放系统和电源,所述电源连接播放系统、显示器和透明显示屏的电源端,所述播放系统的输出端连接显示器和透明显示屏的信号输入端。
所述透明显示屏为无背光液晶透明显示屏,或者为透明有机发光二极管屏幕。
所述无背光液晶透明显示屏设有两片玻璃,其中一片玻璃上制备有薄膜晶体管驱动电路层,另一片玻璃上制备有液晶层,所述液晶层贴合在薄膜晶体管驱动电路层上,两片所述玻璃外均设有偏光片,所述液晶层由上电极和下电极夹持液晶构成。
所述透明有机发光二极管屏幕设有制备在玻璃上的薄膜晶体管驱动电路层,所述薄膜晶体管驱动电路层上制备有阳极,所述阳极上制备有有机发光层,所述有机发光层上只有阴极,所述阴极与阳极、有机发光层之间填充用像素定义层,所述阴极外设有封装层。
本发明显示系统通过多显示器的叠加效应,实现分区域独立调节透光率,改善近眼显示系统的对比度、亮度和色域,提升显示性能,解决低对比度,低亮度,低色域导致的显示问题,满足室外或强光环境下的应用,提升用户体验,拓宽了近眼显示系统的应用场景。
附图说明
下面对本发明说明书中每幅附图表达的内容及图中的标记作简要说明:
图1为近眼显示眼镜结构示意图;
图2为透明显示屏为无背光液晶透明显示屏层结构示意图;
图3为透明有机发光二极管屏幕层结构示意图。
具体实施方式
下面对照附图,通过对实施例的描述,本发明的具体实施方式如所涉及的各构件的形状、构造、各部分之间的相互位置及连接关系、各部分的作用及工作原理、制造工艺及操作使用方法等,作进一步详细的说明,以帮助本领域技术人员对本发明的发明构思、技术方案有更完整、准确和深入的理解。
近眼显示眼镜如图1所示,包括眼镜框、固定在眼镜框两侧的眼镜腿、以及固定在眼镜框上的镜片,镜片为可以为两个独立的镜片,分部位于眼镜框的两侧,也可以采用一体式镜片,但也分为左半部分和右半部分,分别用于遮挡住左眼和右眼。两根眼镜腿的前端固接在眼镜框的两侧,眼镜腿的前部为固定且不可以弯折的,其也可以定义为眼镜框的一部分。
每个眼镜腿的前端均设有光波导入射光栅,光波导入射光栅的折射面朝向眼镜腿后端,折射方向朝向镜片一侧,在每个镜片表面或镜片内设有光波导出射光栅,眼镜腿内安装有朝向光波导入射光栅投影的显示器,显示器的显示方向朝向光波导入射光栅,用于将图像投射到光波导入射光栅上,光波导入射光栅将显示器投影的图像衍射至所在侧镜片内的光波导出射光栅上显示,光波导入射光栅和显示器之间无遮挡,之间具有间隙,间隙可以是空气,也可以是玻璃,光波导入射光栅和光波导出射光栅之间也无遮挡,两者之间的光路经过玻璃镜片。其中,显示器可选硅基液晶(LCOS),数字光处理(DLP),硅基有机发光二极管(Micro OLED),微米发光二极管(Micro LED),激光扫描显示(LBS)等
每个镜片的外表面固定有透明显示屏,可选无背光液晶透明显示屏,透明有机发光二极管等。眼镜框或眼镜腿上固定有播放系统和电源,电源连接播放系统、显示器和透明显示屏的电源端,播放系统的输出端连接显示器和透明显示屏的信号输入端,构成一个可以进行播放的成像眼镜。
主显示器负责显示图像,图像经过光波导传导,并输出到人眼。副显示器负责提升对比度、亮度和色域,副显示器和主显示器显示内容一样。副显示器如果采用无背光液晶透明显示屏,只显示黑白画面,副显示器如果采用透明发光二极管显示屏,可显示黑白画面和彩色画面。工作时,副屏图像上不透光部分可以减少自然光通过率,同时副屏图像上的透光部分自然光可以透过,能够实现分区域独立控制自然光的透过率,在减少图像区域透光的前提下,保证其它区域的透光性。通过多显示器的叠加效应,实现分区域独立调节透光率,改善近眼显示系统的对比度、亮度和色域,提升显示性能,解决低对比度,低亮度,低色域导致的显示问题,满足室外或强光环境下的应用,提升用户体验,拓宽近眼显示系统的应用场景。
