The existing augmented reality display system usually consists of an optical engine and an optical combiner. The optical combiner reflects the image of the optical engine into the human eye and maintains a certain transmittance of ambient light. The existing augmented reality display system cannot be In the case of cost, high performance realizes the reflection of the image and the transmission of the ambient light, which leads to the fact that the existing low-cost AR display system cannot achieve high imaging brightness.

The terms used in the embodiments of the application herein are only for the purpose of describing specific implementation manners, and are not intended to limit the application.
在增强现实显示技术领域中，从光源的方面看，主要包括基于传统显示面板的TFT-LCD/AM-OLED(TFT-LCD：薄膜晶体管液晶显示器；AM-OLED：有源矩阵有机发光二极体或主动矩阵有机发光二极体)显示屏幕、基于DLP(DLP：数字光处理)以及3LCD(3LCD：将光源发出的光分解成R(红)、G(绿)、B(蓝)三种颜色(光的三原色)的光)的LED(LED：发光二极管)/激光光源投影技术、基于LCOS(LCOS：液晶附硅)的光源技术以及基于MEMS(MEMS：微机电***)***的激光扫描方案。从光学组合器方面来看，主要包括Birdbath(Birdbath：曲面反射镜)、自由曲面、几何光波导(又称阵列光波导)以及衍射光波导技术(包括表面浮雕光栅和全息体光栅)。其中，Birdbath、自由曲面、阵列光波导都是基于几何光学的技术。Birdbath以及自由曲面技术通过对光线的定向反射以及表面的半透半反镀膜实现光学组合的功能，相关技术生产成本较低，并且可以实现很大的视场角。但是由于此类技术难以在薄片式镜片上实现，基于此技术的产品通常难以具有普通眼镜的轻便形态。并且由于半透半反膜层的存在，在一定程度上会影响周围环境的光线，无法保证不影响用户对周围环境的观察。阵列光波导技术是将自由曲面的反射面做成多层反射阵列膜层，以减小产品体积，但是由于工艺难度极高，成本一直居高不小。In the field of augmented reality display technology, from the perspective of light sources, it mainly includes TFT-LCD/AM-OLED based on traditional display panels (TFT-LCD: thin film transistor liquid crystal display; AM-OLED: active matrix organic light-emitting diode Or active matrix organic light emitting diode) display screen, based on DLP (DLP: digital light processing) and 3LCD (3LCD: decompose the light emitted by the light source into R (red), G (green), B (blue) three colors (Light of the three primary colors of light) LED (LED: Light Emitting Diode)/laser light source projection technology, LCOS (LCOS: Liquid Crystal with Silicon)-based light source technology, and MEMS (MEMS: Micro Electro Mechanical System) system-based laser scanning solution. From the perspective of optical combiners, it mainly includes Birdbath (Birdbath: curved mirror), free-form surface, geometric optical waveguide (also known as array optical waveguide) and diffractive optical waveguide technology (including surface relief grating and holographic volume grating). Among them, Birdbath, free-form surfaces, and arrayed optical waveguides are all technologies based on geometric optics. Birdbath and free-form surface technology realize the function of optical combination through the directional reflection of light and the transflective coating on the surface. The related technology has low production cost and can achieve a large field of view. However, since this type of technology is difficult to implement on thin-film lenses, it is usually difficult for products based on this technology to have the lightweight form of ordinary glasses. Moreover, due to the existence of the semi-transparent and semi-reflective film layer, it will affect the light of the surrounding environment to a certain extent, and there is no guarantee that it will not affect the user's observation of the surrounding environment. Array optical waveguide technology is to make the reflective surface of the free-form surface into a multilayer reflective array film to reduce the volume of the product, but due to the extremely difficult process, the cost has always been high.
目前，市场上也存在基于衍射光波导技术的AR眼镜，衍射光波导技术是基于微纳光学的技术，衍射光波导多采用具有表面浮雕结构的光栅或者全息体光栅。对于表面浮雕光栅来说，传统的矩形光栅虽然加工工艺成熟，可量产型好，但是会带来光效利用率的问题。对于全息体光栅来说，由于材料和结构的限制，能实现的折射率调制比较有限，使其在可视角、光效率和清晰度上依然落后于表面浮雕光栅，并且制备工艺也存在成本高、难量产的问题。另外，基于衍射光学技术 的光学组合器，由于其对波长衍射角度的高度选择性，极易造成色散现象，对工艺精度要求极高，也进一步造成了该技术成本的提高。因此，基于衍射光波导技术的AR眼镜价格较高。低成本、低功耗、小型化、高成像亮度、高透光率的AR产品是未来技术主要追求的方向。At present, AR glasses based on diffractive optical waveguide technology also exist on the market. Diffractive optical waveguide technology is based on micro-nano optics technology. Diffractive optical waveguides mostly use gratings with surface relief structures or holographic volume gratings. For the surface relief grating, although the traditional rectangular grating has mature processing technology and can be mass-produced, it will bring about the problem of light efficiency utilization. For holographic volume gratings, due to the limitations of materials and structures, the refractive index modulation that can be achieved is relatively limited, making it still lagging behind surface relief gratings in terms of viewing angle, light efficiency, and clarity, and the manufacturing process also has high costs, The problem of difficult mass production. In addition, the optical combiner based on diffractive optics technology, due to its high selectivity of the wavelength diffraction angle, is very easy to cause dispersion, and requires extremely high process accuracy, which further increases the cost of the technology. Therefore, AR glasses based on diffractive optical waveguide technology are relatively expensive. AR products with low cost, low power consumption, miniaturization, high imaging brightness, and high light transmittance are the main pursuits of future technology.
因此，经过长期研究，发明人提供了一种增强现实显示光学器件、光学***、眼镜及HUD显示***，以实现低成本、高光效的增强现实显示。Therefore, after long-term research, the inventor provides an augmented reality display optics, optical system, glasses, and HUD display system to realize a low-cost, high-efficiency augmented reality display.
第一实施例The first embodiment
请参阅图1，本申请实施例提供了一种增强现实显示光学器件10，该增强现实显示光学器件10包括基底层200、多个光致发光体100以及多个微透镜110。基底层200能透射环境光，且基底层200包括第一表面210以及与第一表面210相背的第二表面220，光致发光体100按照预定像素间距分散设置于基底层200内，并且彼此之间间隔设置。多个微透镜110对应的设置于光致发光体100的远离第二表面220的一侧，以汇聚多个光致发光体100发射的光线。Referring to FIG. 1, an embodiment of the present application provides an augmented reality display optical device 10. The augmented reality display optical device 10 includes a base layer 200, a plurality of photoluminescent bodies 100 and a plurality of microlenses 110. The base layer 200 can transmit ambient light, and the base layer 200 includes a first surface 210 and a second surface 220 opposite to the first surface 210. The photoluminescent bodies 100 are dispersedly arranged in the base layer 200 according to a predetermined pixel pitch and are mutually connected. Set the interval between. The plurality of microlenses 110 are correspondingly arranged on the side of the photoluminescent body 100 away from the second surface 220 to converge the light emitted by the plurality of photoluminescent bodies 100.
基底层200可以透过环境光，可以作为贴附层贴附于其他显示设备，使用时，第一表面210可以靠近人眼，环境光例如可以由第二表面220入射至基底层200，并透过基底层200从第一表面210透出并在人眼成像。在一些实施方式中，基底层200可以是平面构型、也可以是自由曲面。本实施例中，第一表面210为自由曲面，第二表面220可以安装贴附于各类显示***，例如AR眼镜的镜片、HUD装置的挡风玻璃以及独立HUD屏幕等，基底层200也可以直接作为AR眼镜的镜片、HUD装置的挡风玻璃以及独立HUD屏幕的全部或者一部分。The base layer 200 can transmit ambient light, and can be used as an attachment layer to be attached to other display devices. When in use, the first surface 210 can be close to human eyes. The base layer 200 penetrates from the first surface 210 and is imaged by the human eye. In some embodiments, the base layer 200 may be a planar configuration or a free-form surface. In this embodiment, the first surface 210 is a free-form surface, and the second surface 220 can be attached to various display systems, such as lenses of AR glasses, windshields of HUD devices, and independent HUD screens. The base layer 200 can also be It is directly used as all or part of the lens of the AR glasses, the windshield of the HUD device and the independent HUD screen.
光致发光体100是指：在受到激发光激发时，可以产生发光现象的发光材料。其中激发光可以是可见光、激光等。作为一种实施方式，光致发光体100可以是 量子点或者纳米荧光粉。其中，量子点是一种纳米级别的半导体，通过对这种纳米半导体材料施加一定的电场或光压，它们便会发出特定频率的光，而发出的光的频率会随着这种半导体的尺寸的改变而变化，因而通过调节这种纳米半导体的尺寸就可以控制其发出的光的颜色。纳米荧光粉是一种纳米材料，能在受到激发时产生荧光。The photoluminescent body 100 refers to a luminescent material that can produce a luminescence phenomenon when excited by excitation light. The excitation light can be visible light, laser, etc. As an embodiment, the photoluminescent body 100 may be quantum dots or nano phosphors. Among them, quantum dots are nano-scale semiconductors. By applying a certain electric field or light pressure to this nano-semiconductor material, they will emit light of a specific frequency, and the frequency of the emitted light will vary with the size of the semiconductor. Therefore, by adjusting the size of this nano-semiconductor, the color of the light emitted can be controlled. Nano-phosphor is a kind of nano-material, which can produce fluorescence when excited.
多个光致发光体100以离散的形式分散设置于基底层200内，且多个光致发光体100是按照预设像素间距分散设置的，像素间距是指相邻的光致发光体100之间的间距。并且在一些实施方式中，多个光致发光体100均匀分布于基底层200内，即相邻的光致发光体100之间具有预定的间隙或者具有预定的像素周期，其中像素周期是指相邻像素之间的间距。A plurality of photoluminescent bodies 100 are dispersedly arranged in the base layer 200 in a discrete manner, and the plurality of photoluminescent bodies 100 are dispersedly arranged according to a preset pixel pitch. The pixel pitch refers to the distance between adjacent photoluminescent bodies 100. The spacing between. And in some embodiments, a plurality of photoluminescent bodies 100 are uniformly distributed in the base layer 200, that is, adjacent photoluminescent bodies 100 have a predetermined gap or a predetermined pixel period, where the pixel period refers to the phase The spacing between adjacent pixels.
在一些实施方式中，多个光致发光体100形成的平面的像素可以是720P、1080P、1920P、2560P等。例如在一些实施方式中，多个光致发光体100的像素周期为25μm-30μm，即相邻的两个光致发光体100的像素间距为25μm-30μm。合适的像素周期值，可以在保证被每一个光致发光体100反射的图像激发光能完整的拼接成图像，避免产生图像重叠，同时也能使环境光具有较好的透过性。In some embodiments, the pixels of the plane formed by the plurality of photoluminescent bodies 100 may be 720P, 1080P, 1920P, 2560P, etc. For example, in some embodiments, the pixel period of the plurality of photoluminescent bodies 100 is 25 μm-30 μm, that is, the pixel pitch of two adjacent photoluminescent bodies 100 is 25 μm-30 μm. A proper pixel period value can ensure that the image excitation light reflected by each photoluminescent body 100 can be completely spliced into an image, avoid image overlap, and at the same time can make the ambient light have better transmittance.
作为一种示例，以基底层200的面积为30mm 2为例，实现1080P的像素分辨率，此时多个光致发光体100的像素周期为30/1080*10 3(μm)27.8μm。当然，可以理解的是，在其他的一些实施方式中，根据像素分辨率大小以及基底层200的面积大小，即可以得到确定的像素周期值。 As an example, taking the area of the base layer 200 of 30 mm 2 as an example to achieve a pixel resolution of 1080P, the pixel period of the multiple photoluminescent bodies 100 at this time is 30/1080*10 3 (μm) 27.8 μm. Of course, it can be understood that, in some other embodiments, a certain pixel period value can be obtained according to the size of the pixel resolution and the size of the area of the base layer 200.
在一些实施方式中，每个光致发光体100的占空比为8％-10％。占空比是指每个像素中，光致发光体100所占的比例。当占空比为8％-10％，光致发光体100形成的遮光范围较小，使得环境光可以很好的依次透过第二表面220、基底层以 及第一表面210，提高环境光的成像效果。当然，可以理解的是，在其他的一些实施方式中，占空比也可以是其他数值。In some embodiments, the duty cycle of each photoluminescent body 100 is 8%-10%. The duty cycle refers to the proportion of the photoluminescent body 100 in each pixel. When the duty cycle is 8%-10%, the light-shielding range formed by the photoluminescent body 100 is small, so that the ambient light can pass through the second surface 220, the base layer and the first surface 210 in sequence, thereby improving the ambient light Imaging effect. Of course, it can be understood that in some other embodiments, the duty cycle may also be other values.
多个光致发光体100可以呈阵列排布，例如呈矩形阵列排布，呈圆形阵列排布等。例如，多个光致发光体100可以在矩形阵列中按照彼此垂直的行和列来排列。这样各个光致发光体100形成的放大图像光刚好可以拼接成完整图像，同时不会发生重叠，此时每一行中的光致发光体100之间的间距可以相等，且每一列中的光致发光体100之间的间距也可以相等。The plurality of photoluminescent bodies 100 may be arranged in an array, for example, in a rectangular array, in a circular array, or the like. For example, a plurality of photoluminescent bodies 100 may be arranged in rows and columns perpendicular to each other in a rectangular array. In this way, the enlarged image light formed by each photoluminescent body 100 can just be stitched into a complete image without overlapping. At this time, the spacing between the photoluminescent bodies 100 in each row can be equal, and the photoluminescent body 100 in each column can be equal. The spacing between the luminous bodies 100 may also be equal.
多个微透镜110对应的设置于多个光致发光体100的远离第二表面220的一侧，以汇聚多个光致发光体100反射的光线，使得被多个光致发光体100反射的光线能够被汇聚到人眼处。其中每个微透镜110根据需要偏折光线的角度进行设置。在一些实施方式中，多个微透镜110对应的汇聚多个光致发光体100发射的光线至主光轴，主光轴是指基底层透射环境光的主光轴，即基底层的焦点所在的光轴上。例如：当基底层贴附于眼镜镜片或者作为眼镜镜片的一部分时，主光轴可以是指镜片的焦点轴线，以使得被多个微透镜110汇聚的光线可以汇聚到人眼成像。The plurality of microlenses 110 are correspondingly arranged on the side of the plurality of photoluminescent bodies 100 away from the second surface 220 to condense the light reflected by the plurality of photoluminescent bodies 100, so that the light reflected by the plurality of photoluminescent bodies 100 Light can be concentrated to the human eye. Each of the microlenses 110 is set according to the angle at which the light needs to be deflected. In some embodiments, the multiple microlenses 110 correspondingly converge the light emitted by the multiple photoluminescent bodies 100 to the main optical axis. The main optical axis refers to the main optical axis through which the base layer transmits ambient light, that is, the focal point of the base layer. On the optical axis. For example, when the base layer is attached to the spectacle lens or used as a part of the spectacle lens, the main optical axis may refer to the focal axis of the lens, so that the light converged by the plurality of microlenses 110 can be converged to the human eye for imaging.
在光致发光体100受激发产生光线时，大部分的光线朝向微透镜110反射，并从第一表面210透过。但仍有一部分的光线会朝向第二表面220一侧出射，这些从第二表面220出射的光线无法进入人眼，会导致光效降低。When the photoluminescent body 100 is excited to generate light, most of the light is reflected toward the microlens 110 and transmitted through the first surface 210. However, a part of the light rays will still exit toward the side of the second surface 220, and the light rays exiting from the second surface 220 cannot enter the human eye, which will reduce the light efficiency.
因此，参阅图2，在一些实施方式中，增强现实显示光学器件还可以包括多个反射元件120，反射元件120的数量、光致发光体100的数量以及微透镜110的数量均可以相等。多个反射元件120对应的设置于光致发光体100的远离第一表面210的一侧，即光致发光体100位于微透镜110和反射元件120之间，使得 环境光可以从相邻的反射元件120之间的间隙透过基底层200。Therefore, referring to FIG. 2, in some embodiments, the augmented reality display optical device may further include a plurality of reflective elements 120, and the number of reflective elements 120, the number of photoluminescent bodies 100, and the number of microlenses 110 may all be equal. A plurality of reflective elements 120 are correspondingly arranged on the side of the photoluminescent body 100 away from the first surface 210, that is, the photoluminescent body 100 is located between the microlens 110 and the reflective element 120, so that the ambient light can be reflected from adjacent ones.
