[0041] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0042] The present application provides a VR device display system, as shown in the accompanying drawings, comprising: an optical module 1, a liquid crystal display screen 2 and an autonomous cleaning structure; the autonomous cleaning structure comprises a transparent photosensitive module 3 located between the optical module 1 and the liquid crystal display screen 2, an ultrasonic motor mechanism 4 located on the central axis of the liquid crystal display screen 2, and a processing unit connected with the transparent photosensitive module 3 and the ultrasonic motor mechanism 4; wherein, Figure 2

[0043] The transparent photosensitive module 3 is used for performing global light detection on the decontamination detection light in units of local areas after the liquid crystal display screen 2 emits the decontamination detection light.

[0044] The processing unit is used for judging whether there is dirt on the local area of the liquid crystal display screen 2 according to the detection data of the transparent photosensitive module 3.

[0045] The ultrasonic motor mechanism 4 is used for shaking the liquid crystal display screen 2 to clean the dirt when the processing unit judges that there is dirt on the local area of the liquid crystal display screen 2.

[0046] In the above VR device display system provided by the embodiments of the present application, the autonomous cleaning structure with the combination of the transparent photosensitive module 3, the ultrasonic motor mechanism 4 and the processing unit is designed, the decontamination detection light emitted by the liquid crystal display screen 2 is detected in units of local areas by the transparent photosensitive module 3, the processing unit is used to judge whether there is dirt on the local area of the liquid crystal display screen 2, and the ultrasonic motor mechanism 4 is used to shake the liquid crystal display screen 2 when there is dirt, so as to realize the autonomous cleaning function of the VR device display system, keep it in a clear display state for a long time, and solve the problem that the traditional VR device cannot clean the screen.

[0047] It should be noted that the ultrasonic motor structure 4 adopted by the present application has high rotation frequency and low power consumption, and is very suitable for use in electronic products. The processing unit can be a processor in a traditional VR device improved by a software algorithm; of course, it can also be an independent processing unit, and the specific setting mode of the processing unit can be determined according to the actual situation.

[0048] In addition, it should be noted that the decontamination detection light emitted by the liquid crystal display screen 2 can be white light with a specific light intensity, i.e. white light with a calibrated light intensity, with the help of the transparent photosensitive module 3.

[0049] ​Further, in the specific implementation, in the VR device display system provided by the embodiment of the present application, the transparent photosensitive module 3 can be specifically used to collect the light intensity of each local area of the liquid crystal display 2 and transmit to the processing unit when global light detection is performed.

[0050] As shown in Figure 3 After the liquid crystal display 2 emits white light with a specific light intensity, the transparent photosensitive module 3 can collect the light intensity of the local module of the liquid crystal display 2. In actual application, the transparent photosensitive module 3 includes a plurality of photosensitive units, each of which corresponds to each local module of the liquid crystal display; the area where the local module is located is the local area. When the surface of the transparent photosensitive module 3 is irradiated by the detection light emitted by the liquid crystal display 2, each photosensitive unit will reflect the charge on the module. The light intensity related data generated by each photosensitive unit will be transmitted to the processing unit.

[0051] In the specific implementation, in the VR device display system provided by the embodiment of the present application, the processing unit can be specifically used to compare the light intensity detected by the transparent photosensitive module 3 with the preset light intensity; when the light intensity is less than the preset light intensity, it is judged that the local area corresponding to the liquid crystal display 2 is dirty; when the light intensity is greater than or equal to the preset light intensity, it is judged that the local area corresponding to the liquid crystal display 2 is not dirty.

[0052] As shown in Figure 4 The processing unit compares the light intensity detected by the transparent photosensitive module 3 with the preset light intensity to determine whether the local area is dirty. If there is dirt on the liquid crystal display 2, such as Figure 4 The A area, B area and C area on the liquid crystal display 2, the processing unit will determine that the A area, B area and C area are dirty according to the comparison result between the light intensity detected by the transparent photosensitive module 3 and the preset light intensity.

[0053] In the specific implementation, in the VR device display system provided by the embodiment of the present application, the processing unit can also be used to calculate the shaking frequency and shaking time required by the ultrasonic motor mechanism 4 to process the dirt and transmit to the ultrasonic motor mechanism 4 when it is judged that the local area corresponding to the liquid crystal display 2 is dirty.

[0054] In the specific implementation, in the VR device display system provided by the embodiment of the present application, the ultrasonic motor mechanism 4 can be specifically used to control the liquid crystal display 2 to shake along the central axis according to the shaking frequency and shaking time calculated by the processing unit. That is, the ultrasonic motor mechanism 4 can clean the dirt according to the shaking frequency and shaking time given by the processing unit.

[0055] AsFigure 5 As shown, by means of the ultrasonic motor mechanism 4, the liquid crystal display screen 2 can be left and right shaken along the central axis according to a given flip angle a, and dust on the liquid crystal screen is shaken off through physical shaking, so as to realize the screen dust removal function. In actual application, the flip angle a can be set to 10° to 20°, and of course can also be other angles, which is specifically required to be determined according to the size and shape of the VR device, and is not limited here.

[0056] Based on the same inventive concept, the embodiment of the present application also provides an autonomous cleaning method of a VR device display system.
