Problems solved by technology

[0003] However, there are potential side effects of the virtual reality system. In the virtual reality, the uncoordinated body and brain will produce discomfort.
Prolonged periods of incoordination can negatively affect the body's hand-eye coordination, balance, and multitasking abilities
At the same time, the human eye will feel uncomfortable when watching 3D effects for a long time, such as eye fatigue and eye swelling, so that users cannot use VR equipment for a long time, which has become a limitation of VR equipment.
[0004] At the same time, users with different eyesight will see different images when wearing VR devices.
The same picture is very clear for users with normal eyesight, but it will be blurred for users with nearsightedness or farsightedness, and the effect of the picture seen by users with different degrees of myopia or hyperopia will also be different. During the viewing process, it is impossible to find a suitable viewing point or feel dizzy, which affects the overall experience. This is another difficulty in the popularization of VR devices.
[0005] In addition, the virtual scene displayed on the VR device needs to be close to the real 3D interface. When the user experience changes in the visual scene, the display size ratio may be diversified, and the final object viewed is larger or larger than the actual one. Too small, affecting the user's sense of intrusion and experience

Embodiment 1

[0032] figure 1 It is a schematic diagram of the composition and structure of the display part of the virtual reality device according to an embodiment of the present invention; the virtual reality device based on the controllable liquid crystal lens described in this embodiment may generally include a display screen 1 and a screen set in front of the display screen 1 The controllable liquid crystal lens 2, the so-called front refers to the front side of the display screen 1 facing the user, that is to say, the controllable liquid crystal lens 2 is arranged between the display screen 1 and human eyes. The controllable liquid crystal lens 2 includes a plurality of electrodes, wherein the plurality of electrodes include at least two ring-shaped electrodes arranged in the controllable liquid crystal lens.

[0033] The virtual reality device based on the controllable liquid crystal lens 2 adopts the annular electrode as the control electrode in the controllable liquid crystal lens...

Embodiment 2

[0042] This embodiment provides an adjustment method for the controllable liquid crystal lens-based virtual reality device described in Embodiment 1, Figure 7 It is a block diagram of the working principle of the virtual reality device in this embodiment. After the picture is input, first refer to the existing scene ratio or through the external control input to control the scaling and adjustment of the image scene through the system as a whole, and then drive the work of the display screen through the display screen; and 3D display is required At this time, the refraction of the controllable liquid crystal lens is controlled by controlling the driving voltage of the liquid crystal lens (that is, the input voltage sent to each input electrode). That is to say, the preliminarily processed picture is converted into a signal matching the display screen through the display drive unit, and input to the display screen for display; at the same time, the driving voltage part of the li...

Abstract

The invention provides a virtual reality device based on a controllable liquid crystal lens, and relates to the technical field of three-dimensional display. The virtual reality device comprises a display screen and a controllable liquid crystal lens, wherein the controllable liquid crystal lens is arranged on the display screen; the controllable liquid crystal lens comprises a plurality of electrodes; the electrodes are annularly arranged in the controllable liquid crystal lens. As the concentric and annular electrodes are taken as control electrodes, and the electrodes are respectively powered, the focus can be adjusted at any time, the adjustment range is relatively large, and relatively clear display images can be provided. The invention further provides an adjusting method of the virtual reality device. By adopting the adjusting method, the virtual reality device can be applicable to people with different eye sights, and the demands of users of different eye sights can be met.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a virtual reality device based on a controllable liquid crystal lens and an adjustment method thereof. Background technique [0002] At present, virtual reality technology allows users to wear VR (Virtual Reality, virtual reality) equipment, people's left eye can see the left viewpoint image, and the right eye can see the right viewpoint image, and through the fusion of the brain, they can see the 3D display effect. With the helmet-mounted device, people's eyes only see the picture on the display screen inside the helmet, so there is a sense of intrusion and immersive feeling. [0003] However, there are certain potential side effects of the virtual reality system. In virtual reality, the uncoordinated body and brain will produce discomfort. Being in a state of incoordination for long periods of time can negatively affect the body's hand-eye coordination, balance an...
