Virtual Reality (VR) is a computer simulation technique that creates and experiences a Virtual world. The virtual reality terminal equipment can simulate and generate a virtual world of a three-dimensional space through a computer technology, and provide simulation of senses such as vision and the like for a user, so that the user feels like the experience of the user. In some application scenarios, the terminal device of the virtual reality includes a display device and an imaging device. For example, the imaging device includes a lens (typically including one or two lenses, but not limited to). The display device includes a display screen disposed opposite the lens. In this way, the user can view the image displayed on the display device through the lens to perceive the corresponding virtual imagery. Here, the display device may be integrated into a virtual reality terminal device, or may be implemented as a detachable mobile device (e.g., a computing device such as a mobile phone or a palm computer.)
Fig. 1 illustrates a schematic structural diagram of a virtual reality terminal device according to some embodiments of the present application. Fig. 2 shows a schematic view of the lens and the display screen arranged opposite to each other on the terminal device of fig. 1. Fig. 3 shows a schematic cross-sectional view of the terminal device of fig. 1.
As shown in fig. 1, the terminal device for virtual reality includes a display device 1, an imaging device 2 disposed opposite to the display device 1, and a support 3. The support 3 is adapted to support the display apparatus 1 and the imaging apparatus 2. As shown in fig. 2, the display device 1 may for example comprise a display screen 11. The imaging device 2 may for example comprise a lens 21. Here, the lens 21 is, for example, an aspherical mirror or a fresnel lens or the like. The support 3 can also be considered as a housing of the terminal device. Here, the Virtual reality terminal device may be implemented as various specific head-mounted Virtual reality devices (Virtual reality heads, abbreviated as VRH) such as a head-mounted display (HMD), Virtual reality glasses (abbreviated as VRG), and the like, which is not limited in this application. From a functional perspective, the terminal device of the virtual reality can be viewed by the user with one or both eyes. In other words, the virtual reality terminal device may be implemented as a monocular device (e.g., monocular virtual reality glasses, etc.) or a binocular device (e.g., binocular virtual reality glasses, etc.). In some embodiments, the architecture shown in FIG. 1 may be implemented as a monocular device. In still other embodiments, the terminal device of the present application may be implemented as a binocular device. The configuration shown in fig. 1 is part of a binocular device. When implemented as a binocular device, the terminal device may generally include two lenses 21 and two display screens 11. Each lens 21 corresponds to a display screen 11. The two display screens 11 may display different images. On the basis of the three-dimensional image, the user can watch the three-dimensional image through the two display screens. In addition, the terminal device may also be configured to include two lenses 21 and one display screen 11. Through the two lenses, the user can see different images respectively (for example, the user sees an odd frame image displayed on the display screen through one lens and an even frame image displayed on the display screen through the other lens).
Fig. 3 shows a schematic cross-sectional view of the virtual reality terminal device in fig. 1. As shown in fig. 3, the terminal device of the virtual reality further includes a dust removing device 31 disposed on the support 3. When foreign matter (e.g., dust or water droplets, etc.) is attached to the display apparatus 1 and/or the imaging apparatus 2, the dust removing device 31 may move the foreign matter relative to the apparatus to which it is attached so that the foreign matter is detached from the attached apparatus. Here, the foreign matter is, for example, contaminants attached during the assembly of the terminal device, fine particles generated by damage inside the device during the use of the terminal device, or water drops condensed inside the device when the temperature changes, and the like.
The dust removing device 31 is further described below with reference to fig. 4. Fig. 4 shows an imaging schematic diagram of the terminal device of the virtual reality in fig. 1. As shown in fig. 4, when the display screen 11 is viewed through the lens 21 from the position P, the virtual image seen by the user is located in the plane area V. FIG. 4 shows an exemplary foreign matter (dust)Or water droplets) occupied area S1. Region S1May obstruct one or more pixel display elements (each of which may mix the display color of the display element with three display colors, red, green, and blue (RGB)) on the display screen 11. Region S1May be displayed enlarged on the virtual image seen by the user. Region S in plane region V2Is a region S1Is enlarged in the area occupied by the foreign matter. Obviously, a foreign object on the display device 1 may greatly affect the virtual imaging effect since the foreign object will be displayed in an enlarged manner. For example, the foreign substance may cause a phenomenon such as a black dot, a dark spot, or a local blur on the virtual image. Accordingly, the dust removing device 31 can avoid the image of the virtual imaging effect by the foreign matter by removing the foreign matter on the display device 1 or the imaging device 2, thereby greatly improving the user experience.
In one embodiment, the dust removing device 31 may be configured as a vibration device. The vibration device includes, for example, a micro motor (not shown) and an eccentric wheel (not shown) provided on a rotation shaft of the micro motor, but is not limited thereto. Here, the vibration device may vibrate the display apparatus 1 and the imaging apparatus 2. In this way, the foreign substance can move relative to the attached device (i.e., the display device 1 or the imaging device 2). Here, the movement process of the foreign matter causes the surface adsorption force of the foreign matter to be reduced, and the frictional force is also reduced, so that the foreign matter is detached from the attached equipment. In yet another embodiment, the dust removing device 31 may be configured as an ultrasonic device. The ultrasonic device can send out the ultrasonic wave (frequency is higher than 20000 hertz's sound wave promptly, and the directionality is good, and the penetration ability is strong, easily obtains more concentrated acoustic energy) for the air vibration between display device 1 and the imaging device 2, thereby drive the foreign matter vibration, and then make the foreign matter finally leave adnexed equipment. It should be noted that the dust removing device 31 may include one or more operation modes.

Here, the parameters of the predetermined operation mode include a predetermined vibration frequency, a predetermined vibration amplitude, and a predetermined vibration direction of the dust removing device 31. The controller may also generate a dust removal instruction corresponding to the predetermined operation mode, and drive the dust removal device to operate in accordance with the generated dust removal instruction. In yet another embodiment, the controller may generate a corresponding dust removal indication in response to a button operation for dust removal. Based on the dust removal instruction, the controller may drive the dust removal device 31 to operate in the operation mode corresponding to each of the plurality of time periods. Here, the plurality of time periods may be continuous or discrete, and the present application does not limit this. Wherein, the working mode corresponding to each time slot means that: and vibrating according to the vibration parameters corresponding to the time period.

In the above-described embodiment, by vibrating in accordance with the respective operation modes at each period (generally, the operation modes at different periods are different), the dust removing device can cause the foreign matter and the attached device to perform different relative movements at different periods, so that the possibility of the foreign matter being removed can be greatly increased. Note that the controller may be implemented by a logic gate, a switch, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, a microcontroller, or the like, or may be implemented as an application executed by a processor (CPU) of the terminal device, which is not limited in this application.
In some embodiments, the surface of the display screen 11 may be provided with a hydrophobic coating, and the surface of the lens 21 may also be provided with a hydrophobic coating. Here, the hydrophobic plating film may reduce the surface energy. Thus, the hydrophobic coating film can make the foreign matters (especially water drops) on the surfaces of the display screen 11 and the lens 21 easier to move, so that the foreign matters are easier to remove.
In some embodiments, the virtual reality terminal device may further include an adsorbing material at the respective edges of the display screen 11 and the lens 21.
