Problems solved by technology

[0003] In order to meet the various needs of users, the existing head-mounted display device can adjust the distance between the lens and the display screen, so that users with ametropia can use the head-mounted display device, but the head-mounted display device in the prior art The traditional display device cannot be adjusted accurately to adapt to the normal use of users with refractive errors. When users with refractive errors use it, if they want to obtain clear images from the display screen, they can only adjust the distance between the display screen and the lens through subjective judgment. distance, so the adjustment result is inaccurate

Abstract

The invention discloses a head-mounted display device and a lens adjustment method. The device comprises an optometry module, a lens adjustment module, a control module and a display module, wherein the lens adjustment module comprises at least two lenses; the output end of the optometry module is connected to the input end of the control module, and the output end of the control module is connected to the control end of the lens adjustment module; and the optometry module detects the diopter of the user's eyes and sends the diopter to the control module, the control module generates a movement instruction according to the diopter and sends the movement instruction to the lens adjustment module, and the lens adjustment module controls the corresponding lens to move according to the movement instruction so as to enable the lens to drop into the display module. The embodiment of the invention improves the adjustment precision of the head-mounted display device.

Description

technical field [0001] Embodiments of the present invention relate to wearable device technology, in particular to a head-mounted display device and a lens adjustment method. Background technique [0002] The head-mounted display device is a new technology in modern display technology. The development of high-resolution image reconstruction technology, the perfection of binary optics theory and design, and the maturity of holographic technology have opened up new possibilities for the design of head-mounted display devices. The new approach has also brought more and more head-mounted display devices into the public eye. [0003] In order to meet the various needs of users, the existing head-mounted display device can adjust the distance between the lens and the display screen, so that users with ametropia can use the head-mounted display device, but the head-mounted display device in the prior art The traditional display device cannot be adjusted accurately to adapt to the ...
