Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and particularly to an anti-glare curved OLED display screen for VR devices. Background Art

[0002] The booming development of virtual reality technology has enabled VR glasses to be widely used in many fields such as gaming, film and television, education, and medical care. Among them, OLED display screens have become one of the mainstream choices for VR glasses display screens due to their excellent high brightness, wide viewing angle, and fast response time and other characteristics.

[0003] During the long-term use of VR glasses, due to their complex and diverse usage environments, dust and various fine particles inevitably tend to accumulate on the screen surface. These dust and particles will adhere to the screen surface, having a serious negative impact on the display effect. On the one hand, they will block part of the light, causing the contrast of the image displayed on the screen to decrease and the color vividness to reduce; on the other hand, the irregular shapes and distributions of the dust and fine particles will cause the light to scatter, making the picture become blurred, greatly reducing the user's immersive experience. During the use process, users may be frequently distracted due to poor picture quality and unable to fully immerse themselves in the virtual world, seriously affecting the use value of VR glasses and user satisfaction.

[0004] However, the internal space of VR glasses is relatively narrow and the screen structure is complex, which poses a great challenge to screen cleaning. Traditional physical wiping and cleaning methods, such as using ordinary cleaning cloths or tissues for wiping, are difficult to be effectively implemented in this special environment. First of all, the narrow space makes it difficult for cleaning tools to smoothly reach all parts of the screen, and it is easy to leave cleaning dead corners; secondly, due to the complex screen structure, there are various protrusions, depressions, and areas closely adjacent to other components. During the wiping process, the cleaning cloth or tissue is easily stuck or wound by these structures. Not only can the screen not be thoroughly cleaned, but it may also cause scratches or damage to the screen surface due to forced pulling. Once scratches appear on the screen surface, the optical performance of the screen will be permanently damaged, further exacerbating the deterioration of the display effect, shortening the service life of VR glasses, and increasing the user's usage cost.

[0032] The present invention will be further described in conjunction with the following embodiments.

[0033] It can be seen from Figures 1 to 8 that an anti-glare curved OLED display screen for a VR device described in this embodiment includes an outer shell 1 and a frame 11 provided on the outer shell 1; the frame 11 is provided with a lens 12;

[0034] A housing 2 is provided inside the outer shell 1; a display screen 3 is provided on the housing 2; the display screen 3 is disposed opposite to the lens 12; a first cleaning component is hingedly provided on one side of the display screen 3 of the housing 2; a second cleaning component is hingedly provided on the other side of the display screen 3 of the housing 2;

[0035] Both the first cleaning component and the second cleaning component include a rubber frame 4, a first static belt 61 movably provided in the rubber frame 4, and a second static belt 62 movably provided in the rubber frame 4; a first insulating belt 63 is provided between one end of the first static belt 61 and one end of the second static belt 62; a second insulating belt 64 is provided between the other end of the first static belt 61 and the other end of the second static belt 62;

[0036] A grounding terminal 41 is provided on the side surface of the rubber frame 4 away from the display screen 3.

[0037] Specifically, for the anti-glare curved OLED display screen for a VR device described in this embodiment, the first static belt 61 and the second static belt 62 are respectively isolated by the first insulating belt 63 and the second insulating belt 64, so that the static electricity between the first static belt 61 and the second static belt 62 is interconnected;

[0038] When the first static belt 61 and the second static belt 62 move in the rubber frame 4, the friction between the first static belt 61 and the rubber frame 4 and the friction between the second static belt 62 and the rubber frame 4 generate static electricity, so that both the first static belt 61 and the second static belt 62 carry static electricity. When the rubber frame 4 and the housing 2 are in a closed state, the static belt on the side close to the display screen 3 can adsorb the dust on the surface of the display screen 3 through static electricity, and this static belt can drive the dust to the side away from the display screen 3.

[0039] In this embodiment, by providing the first static electricity belt 61 and the second static electricity belt 62, static electricity is generated through friction with the rubber frame 4, so that the static electricity belt on the side close to the display screen 3 can adsorb the dust on the surface of the display screen 3 through static electricity, and then the static electricity belt can drive the dust to the side away from the display screen 3 for cleaning, thereby effectively cleaning the display screen 3 and preventing damage to the display screen 3 at the same time.

[0040] For an anti-glare curved OLED display screen for a VR device in this embodiment, a main rotating roller 51 and a driven rotating roller 52 are respectively rotatably provided at both ends of the rubber frame 4; the first static electricity belt 61, the first insulating belt 63, the second static electricity belt 62 and the second insulating belt 64 are sleeved between the main rotating roller 51 and the driven rotating roller 52.

[0041] Specifically, through the above arrangement, when the main rotating roller 51 rotates, since the first static electricity belt 61, the first insulating belt 63, the second static electricity belt 62 and the second insulating belt 64 are connected as a whole, the first static electricity belt 61, the first insulating belt 63, the second static electricity belt 62 and the second insulating belt 64 can be driven to move along the surface of the rubber frame 4 at the same time.

[0042] For an anti-glare curved OLED display screen for a VR device in this embodiment, a cleaning rod 42 is provided on the side of the rubber frame 4 away from the display screen 3; the cleaning rod 42 is used to contact the first static electricity belt 61 or the second static electricity belt 62; the grounding terminal 41 is used to contact the first static electricity belt 61 or the second static electricity belt 62.

[0043] Specifically, when the rubber frame 4 and the housing 2 are in a closed state, the static electricity belt on the side close to the display screen 3 can adsorb the dust on the surface of the display screen 3 through static electricity, and the static electricity belt can drive the dust to the side away from the display screen 3. Then, the grounding terminal 41 causes the static electricity belt to lose static electricity, and at the same time, the cleaning rod 42 can clean and scrape the dust on the surface of the static electricity belt.

[0044] An anti-glare curved OLED display screen for a VR device according to this embodiment, one end of the rubber frame 4 is hinged to the housing 2; arc-shaped bumps 21 are provided on both sides of the display screen 3 of the housing 2; arc-shaped teeth 22 are provided on the arc-shaped bumps 21; a gear rod 43 meshing with the arc-shaped teeth 22 is rotatably provided at one end of the rubber frame 4. An anti-glare curved OLED display screen for a VR device according to this embodiment, a locking pin 44 is provided on the gear rod 43 in a lifting and moving manner; a first spring is provided between the locking pin 44 and the gear rod 43; a ratchet 53 is provided at the top of the main rotating roller 51; a plurality of locking teeth 54 cooperating with the locking pin 44 are provided extending upward from the ratchet 53; an inclined surface 55 is provided on the locking teeth 54. An anti-glare curved OLED display screen for a VR device according to this embodiment, a slider 71 is hinged at one end of the rubber frame 4; a driving member 72 is provided in the housing 2; a push block 73 is provided at the output end of the driving member 72; a sliding groove 74 is provided on the push block 73; one end of the slider 71 is slidably arranged in the sliding groove 74; the other end of the slider 71 is hinged to one end of the rubber frame 4. Wherein the driving member 72 can be a cylinder, an oil cylinder or an electric cylinder, etc.

[0045] Specifically, for the anti-glare curved OLED display screen for a VR device according to this embodiment, first, the rubber frame 4 and the housing 2 are in a closed state. When the VR device needs to be used, the driving member 72 drives the push block 73 to move outward, so that the rubber frame 4 gradually opens. During the opening process of the rubber frame 4, the arc-shaped teeth 22 and the gear rod 43 are engaged, so the gear rod 43 rotates synchronously. At this time, the locking teeth 54 and the locking pin 44 are locked, so when the gear rod 43 rotates, it drives the main rotating roller 51 to rotate synchronously, so that the first static belt 61, the first insulating belt 63, the second static belt 62 and the second insulating belt 64 move along the surface of the rubber frame 4 at the same time, so that static electricity is generated on the surface of the first static belt 61 and the surface of the second static belt 62. When the rubber frame 4 is completely opened, at this time, one of the static belts is located on one side surface of the rubber frame 4 close to the display screen 3, and the other static belt is located on the side surface of the rubber frame 4 far from the display screen 3. Since the grounding terminal 41 is located on the side surface far from the display screen 3, the static belt on the side surface far from the display screen 3 loses static electricity, and the static belt on the side surface close to the display screen 3 still has static electricity;

[0046] When it is necessary to clean the real screen, the driving member 72 drives the pushing block 73 to move inwards, so that the rubber frame 4 gradually closes. During the closing process of the rubber frame 4, under the action of the inclined surface 55, the gear rod 43 cannot drive the main rotating roller 51 to rotate, so that the first static belt 61, the first insulating belt 63, the second static belt 62 and the second insulating belt 64 remain stationary until the rubber frame 4 is completely closed. When the static belt on the side close to the display screen 3 adsorbs the dust on the display screen 3 through static electricity;

[0047] When the rubber frame 4 is opened next time, the first static belt 61, the first insulating belt 63, the second static belt 62 and the second insulating belt 64 become active again. When the static belt with dust passes through the side away from the display screen 3, under the action of the grounding terminal 41, the static electricity of the static belt is lost, and at the same time, the cleaning rod 42 can clean and scrape the dust on the surface of the static belt.

[0048] For an anti-glare curved oled display screen for a VR device described in this embodiment, the widths of the first static belt 61 and the second static belt 62 are the same as the distance between the main rotating roller 51 and the driven rotating roller 52; the widths of the first insulating belt 63, the second insulating belt 64, half of the circumference of the main rotating roller 51 and half of the circumference of the driven rotating roller 52 are the same. Through the above settings, when the rubber frame 4 is completely opened or completely closed, the first insulating belt 63 and the second insulating belt 64 can be respectively arranged on both sides of the rubber frame 4, so as to effectively improve the cleaning efficiency.

[0049] For an anti-glare curved oled display screen for a VR device described in this embodiment, the length of the grounding terminal 41 is greater than the lengths of the first static belt 61 and the second static belt 62. Through the above settings, the static electricity on the static belt on the side away from the display screen 3 can be effectively eliminated.

[0050] For an anti-glare curved oled display screen for a VR device described in this embodiment, the length of the cleaning rod 42 is greater than the lengths of the first static belt 61 and the second static belt 62. Through the above settings, the dust on the static belt on the side away from the display screen 3 can be effectively cleaned.

[0051] A glare-proof curved OLED display screen for a VR device according to this embodiment, a fixing frame 8 is movably arranged along the width direction of the housing 2; the display screen 3 is arranged on the fixing frame 8; a second spring 81 is arranged between the fixing frame 8 and the housing 2. Specifically, in order to prevent a gap from existing between the two rubber frames 4 when they are completely closed and dust in the gap cannot be effectively cleaned, the fixing frame 8 and the second spring 81 are arranged, so that during the opening process of the rubber frame 4, the display screen 3 can be pushed to move a small distance, thereby ensuring that the entire display screen 3 can be cleaned.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
