Head-mounted display

Abstract

The invention relates to a head-mounted display. The display comprises a main body framework. The main body framework is provided with left and right display screens and left and right eye lenses which are correspondingly arranged with the left and right display screens. The main body framework is provided with a diopter and pupillary distance adjusting mechanism used for simultaneously adjusting a distance between a single side display screen and the eye lenses and adjusting a distance between the two eye lenses. The diopter and pupillary distance adjusting mechanism comprises a driving component and a rotary knob component. The diopter and pupillary distance adjusting mechanism adopts rotation and slide operation of the same rotary knob component to realize diopter and pupillary distance adjusting of the head-mounted display respectively. Through rotating the rotary knob component, the diopter of the head-mounted display can be adjusted, and through sliding the rotary knob component, a pupillary distance of the head-mounted display can be adjusted. Operation is easy, a product structure is simplified, a product size of the head-mounted display is compact, weight is light and usage is comfortable and convenient.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, and more specifically, to a head-mounted display. Background technique [0002] With the continuous development of electronic devices towards ultra-miniaturization, as well as the development of new computer, microelectronics, optoelectronic devices and communication theories and technologies, wearable computing, a new model based on "people-oriented" and "integration of man and machine" has become possible. . Applications are emerging in military, industrial, medical, education, consumer and other fields. In a typical wearable computing system architecture, the head-mounted display device is a key component. The head-mounted display device guides the video image light emitted by the micro-image display (such as transmissive or reflective liquid crystal display, organic electroluminescent device, DMD device) to the user's pupil through optical technology, and the user's ne...

Problems solved by technology

[0007] Both the above-mentioned second and third schemes can realize the adjustment of the diopter (diopter) and the interpupillary distance at the same time, but it is necessary to drive the bilateral lenses or lens barrels to move at the same time to realize the adjustment of the interpupillary distance, which is not only complicated in structure and large in size, but also Since there is only one display screen, when the interpupillary distance is adjusted, the effective display image of the display screen and the double-sided lenses or lens barrels will move relative to each other, resulting in a misalignment between the optical center and the display center, which directly affects the display effect of the edge screen; at the same time, the diopter During the adjustment process, moving the lens or lens barrel will change the distance between the lens or lens barrel and the display screen at the same time, as well as the distance between the human eye and the lens or lens barrel, that is, changing the eye-to-eye distance, and the change of the eye-to-eye distance It will reduce the accuracy of diopter adjustment, resulting in poor viewing effect

[0008] In addition, since head-mounted displays are currently developing in the direction of compact size, light weight, ease of wearing, and lightening loads, complex structures will inevitably lead to increased volume and weight of head-mounted displays, which will affect the use of head-mounted displays.
