Problems solved by technology
Then for users with different eyesight, because the focal length is shorter, it is not easy to adjust the distance between the microlens array and the display screen, and the effect after adjustment is limited. The current solution to the above technical problems is mainly to adjust the size of the displayed image on the display screen, thereby Adapt to users with different eyesight, but display image processing is more complex and difficult to implement

The present invention provides a near-eye display based on a microlens array, comprising: a display screen for displaying images facing human eyes, a microlens array located between the display screen and human eyes, an eye tracking camera, and an image processing unit, wherein, The microlens array is used to magnify the image displayed on the display screen and project it onto the retina of the human eye. The microlens array includes a plurality of microlens units with the same shape and structure arranged in an array; the display screen displays The image of the image is divided into a plurality of sub-images arranged at intervals with the same shape and size, and each sub-image corresponds to one of the microlens units in the microlens array; the image processing unit is used to divide the original image into The multiple sub-images matched by the microlens array are presented, and the images are adjusted through the position information of the human eye acquired by the eye tracking camera; the eye tracking camera is used to track and acquire the position information of the pupil of the human eye.
Description
technical field [0001] The invention relates to a near-eye display, in particular to a near-eye display capable of displaying images by adapting to the vision state of human eyes. Background technique [0002] A near-eye display (NED) is a display that can project images directly into the eyes of the viewer. It is usually made into a head-mounted display (HMD) for people to wear, so as to achieve an immersive display experience. The display screen of this kind of near-eye display is within ten centimeters from the eyeball, and such close images are conventionally invisible to the human eye. However, near-eye displays focus and project images on the retina of the human eye through a specially designed lens array, and after processing by the visual nervous system, a magnified virtual image is presented in front of the user's eyes, which can be used for virtual or augmented reality applications. [0003] In existing near-eye display devices, the lens array used is a microlens ...
