Translated fromChinese技术领域technical field
本发明涉及VR技术领域，特别涉及一种分段式显示屏及VR设备。The invention relates to the technical field of VR, in particular to a segmented display screen and VR equipment.
背景技术Background technique
VR产品近年来发展迅速，各类光学方案百花齐放。但各方案所涉及到发光源即屏幕时，要么是直板屏幕要么是固定曲率或显示方向的曲面屏、拼接屏，其设计构思是通过增大显示区域(AA区域)进行的视场角、沉浸感等的增强，但都未从根本上解决边缘视场成像质量差等问题。VR products have developed rapidly in recent years, and various optical solutions are flourishing. However, when the light source, that is, the screen, is involved in each scheme, it is either a straight screen or a curved screen with a fixed curvature or display direction, or a splicing screen. However, they have not fundamentally solved the problem of poor imaging quality in the peripheral field of view.
目前上市的各产品光学方案都从提高屏幕分辨率，增大AA区域提高PPI来提升用户沉浸感。屏幕发出的携带图像信息的光线经过透镜后进入人眼，因为透镜对光线的偏折作用，导致图像中心最为清晰，从中心向边缘过渡时，图像的畸变与失真会显著上升，因畸变场曲等影响，屏幕边缘的密集像素点和屏幕中间区域像素点对整体图像的贡献并不相同。增大AA区域后，仍然会存在畸变增大、视线边缘色差明显等影响成像质量加大畸变预校正难度等难题。The optical solutions of each product currently on the market improve the user's sense of immersion by increasing the screen resolution, increasing the AA area and increasing the PPI. The light carrying image information emitted by the screen enters the human eye after passing through the lens. Because of the deflection effect of the lens on the light, the center of the image is the clearest. When transitioning from the center to the edge, the distortion and distortion of the image will increase significantly. and other effects, the dense pixels on the edge of the screen and the pixels in the middle of the screen do not contribute the same to the overall image. After increasing the AA area, there will still be problems such as increased distortion and obvious chromatic aberration at the edge of the line of sight, which will affect the image quality and increase the difficulty of distortion pre-correction.
现有技术中，主要通过后期算法的复杂校正将已失真的图像进行一定程度的还原。但校正效果是有限的，存在一个校正极限值无法被打破。例如一个视场角为105°的虚拟现实头戴类产品，其发光屏幕边缘位置显示的带有图像信息的光线经过透镜后其畸变值会达到30％～40％，经过算法的反向预校正，其图像再经过透镜后，边缘畸变值会降到2％～5％，并不能再进一步降低其畸变值。其瓶颈在于平面屏幕发出的光线其传播过程中各视场光线的光程存在差异，因光程差和透镜自身材料的特性，决定了算法校正方法其存在极限值。若强行校正图像畸变，会使图像产生色差增大、亮度下降等牵连问题。当用户自主观察屏幕显示边缘时会看见一定程度上扭曲且不清晰的图像，影响沉浸感。In the prior art, the distorted image is restored to a certain extent mainly through the complex correction of the post-algorithm. But the correction effect is limited, and there is a correction limit that cannot be broken. For example, for a virtual reality head-mounted product with a field of view of 105°, the light with image information displayed at the edge of the luminous screen will have a distortion value of 30% to 40% after passing through the lens, and the reverse pre-correction of the algorithm , after the image passes through the lens, the edge distortion value will drop to 2% to 5%, and the distortion value cannot be further reduced. The bottleneck lies in the difference in the optical path of the light rays in each field of view during the propagation of the light emitted by the flat screen. Due to the optical path difference and the characteristics of the lens itself, the algorithm correction method has its limit value. If the image distortion is forcibly corrected, the image will have problems such as increased chromatic aberration and decreased brightness. When users independently observe the edge of the screen display, they will see a certain degree of distorted and unclear images, which will affect the sense of immersion.

需要说明的是，所述显示区域等分的方向，可以根据所述显示屏组10的装配方向进行调整，例如当两个所述第二显示部12分别设置在所述第一显示部11的左右两侧时，则可以根据水平方向由左至右或者由右至左划分为n个所述子视场。It should be noted that, the direction in which the display area is equally divided can be adjusted according to the assembly direction of the
具体的，本实施例中，总共将所述显示区域等分为20个所述子视场，即n＝20，而所述第二显示部12上具有七个连续的所述子屏121，对应的，进行显示时，每个所述子屏121依序显示一个所述子视场，所述第一显示部11上则显示六个所述子视场，从而最终在所述显示屏组10上形成全视场图像。Specifically, in this embodiment, the display area is divided into 20 sub-fields of view in total, that is, n=20, and the
在上述过程中，每个所述子屏121可以是平面透镜，当为平面透镜时，相邻两个所述子屏121之间可以具有夹角，夹角的大小可以根据产品型号进行调整，以适应不同型号的产品显示屏组10与用户人眼之间间距大小不同的情况。所述子屏121也可以采用曲面屏的方式，当为曲面屏时，每个所述子屏121的曲率各不相同，且所述子屏121的曲率可以为正值也可以为负值，也即所述子屏121可以向显示面一侧凹陷也可以向显示面一侧凸出，如本实施例图1中则采用凹陷的方式设置，更贴合虚拟现实类产品的成像特点和使用需求。In the above process, each of the
本发明技术方案通过将所述第一显示部11两侧的所述第二显示部12划分为多个连续的所述子屏121。将显示区域拆分为多个所述子视场，并通过每个所述子屏121单独负责显示一份个子视场，最后在整个所述显示屏组10上形成全视场成像效果。有效利用边缘视场的像素点提升用户可观察的图像区域和可见清晰度。The technical solution of the present invention divides the
同时，在提高显示效果的前提下，降低了对图像预校正算法的难度及需求，节省算力。可把节省下的算力用在面部实时追踪、眼球注视点追踪等功能上，为未来VR产品的多功能性提供了方向。进一步提高头戴虚拟现实类产品输出图像质量，使头戴虚拟现实类产品的光学效果更接近现实。At the same time, on the premise of improving the display effect, it reduces the difficulty and demand for the image pre-correction algorithm and saves computing power. The saved computing power can be used for real-time facial tracking, eye gaze tracking and other functions, providing a direction for the versatility of future VR products. Further improve the output image quality of head-mounted virtual reality products, and make the optical effects of head-mounted virtual reality products closer to reality.
