Description

Technical Field

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

[0002] The booming development of virtual reality technology has led to the widespread application of VR glasses in many fields such as games, film and television, education, and medical treatment. Among them, OLED displays have become one of the mainstream choices for VR glasses displays due to their excellent high brightness, wide viewing angle, and fast response time.

[0003] During the long-term use of VR glasses, due to the complex and diverse use environment, dust and various fine particles are inevitably easy to accumulate on the screen surface. These dust and particles will adhere to the screen surface, which will have a serious negative impact on the display effect. On the one hand, they will block part of the light, causing the image contrast and color vividness to decrease; on the other hand, the irregular shape and distribution of dust and fine particles will cause light to scatter, making the picture blurry and greatly reducing the user's immersive experience. During use, users may frequently be distracted by poor picture quality and unable to fully immerse themselves in the virtual world, which seriously affects the use value and user satisfaction of VR glasses.

[0004] However, the internal space of VR glasses is relatively small and the screen structure is complex, which brings great challenges to screen cleaning. Traditional physical wiping cleaning methods, such as wiping with ordinary cleaning cloths or paper towels, are difficult to implement effectively in this special environment. First, the small space makes it difficult for cleaning tools to smoothly contact various parts of the screen, which easily leaves cleaning dead corners; secondly, due to the complex structure of the screen, there are various protrusions, depressions, and areas closely adjacent to other components. During the wiping process, the cleaning cloth or paper towel is easily stuck or entangled 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, it will permanently damage the optical performance of the screen, further aggravate the deterioration of the display effect, shorten the service life of VR glasses, and increase the user's usage cost.

DETAILED DESCRIPTION

[0032] The present invention is further described in conjunction with the following examples.

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

[0034] The housing 1 is provided with a housing 2; the housing 2 is provided with a display screen 3; the display screen 3 is arranged opposite to the lens 12; the housing 2 is hingedly provided with a first cleaning component on one side of the display screen 3; the housing 2 is hingedly provided with a second cleaning component on the other side of the display screen 3;

[0035] The first cleaning assembly and the second cleaning assembly both include a rubber frame 4, a first electrostatic belt 61 movably arranged on the rubber frame 4, and a second electrostatic belt 62 movably arranged on the rubber frame 4; a first insulating belt 63 is arranged between one end of the first electrostatic belt 61 and one end of the second electrostatic belt 62; a second insulating belt 64 is arranged between the other end of the first electrostatic belt 61 and the other end of the second electrostatic belt 62;

[0036] A ground terminal 41 is disposed on a side of the rubber frame 4 away from the display screen 3 .

[0037] Specifically, the VR device described in this embodiment uses an anti-glare curved OLED display screen, and the first electrostatic belt 61 and the second electrostatic belt 62 are isolated by the first insulating belt 63 and the second insulating belt 64 respectively, so that the first electrostatic belt 61 and the second electrostatic belt 62 are electrostatically connected to each other;

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

[0039] In this embodiment, a first electrostatic belt 61 and a second electrostatic belt 62 are provided to generate static electricity through friction with the rubber frame 4, so that the electrostatic belt close to the display screen 3 can absorb dust on the surface of the display screen 3 through static electricity, and then the electrostatic belt can move 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.

[0040] In the anti-glare curved OLED display for VR equipment described in this embodiment, a main rotating roller 51 and a slave rotating roller 52 are rotatably provided at both ends of the rubber frame 4; the first electrostatic belt 61, the first insulating belt 63, the second electrostatic belt 62 and the second insulating belt 64 are sleeved between the main rotating roller 51 and the slave rotating roller 52.

[0041] Specifically, through the above-mentioned arrangement, when the main rotating roller 51 rotates, since the first electrostatic belt 61, the first insulating belt 63, the second electrostatic belt 62 and the second insulating belt 64 are connected as a whole, the first electrostatic belt 61, the first insulating belt 63, the second electrostatic 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] In the anti-glare curved OLED display for VR equipment described 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 electrostatic belt 61 or the second electrostatic belt 62; the grounding terminal 41 is used to contact the first electrostatic belt 61 or the second electrostatic belt 62.

[0043] Specifically, when the rubber frame 4 and the shell 2 are closed, the electrostatic belt close to the display screen 3 can absorb the dust on the surface of the display screen 3 through static electricity, and the electrostatic belt can drive the dust to the side away from the display screen 3, and then the grounding terminal 41 makes the electrostatic belt lose static electricity, and at the same time the cleaning rod 42 can clean and scrape off the dust on the surface of the electrostatic belt.

[0044] In the anti-glare curved OLED display for VR equipment described in this embodiment, one end of the rubber frame 4 is hinged to the shell 2; the shell 2 is provided with arc-shaped protrusions 21 on both sides of the display screen 3; the arc-shaped protrusions 21 are provided with arc-shaped teeth 22; one end of the rubber frame 4 is rotatably provided with a gear rod 43 meshing with the arc-shaped teeth 22. In the anti-glare curved OLED display for VR equipment described in this embodiment, the gear rod 43 is provided with a locking pin 44 for lifting and lowering; a first spring is provided between the locking pin 44 and the gear rod 43; a ratchet 53 is provided on the top of the main rotating roller 51; the ratchet 53 is extended upward and provided with a plurality of locking teeth 54 cooperating with the locking pin 44; the locking teeth 54 are provided with an inclined surface 55. In the anti-glare curved OLED display for VR equipment described in this embodiment, a slider 71 is hingedly provided 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; the push block 73 is provided with a sliding groove 74; one end of the slider 71 is slidably provided in the sliding groove 74; the other end of the slider 71 is hingedly provided with one end of the rubber frame 4. The driving member 72 may be a cylinder, an oil cylinder or an electric cylinder.

[0045] Specifically, the VR device described in this embodiment uses an anti-glare curved OLED display screen. First, the rubber frame 4 and the shell 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 is gradually opened. In the process of opening the rubber frame 4, the arc-shaped teeth 22 are meshed with the gear rod 43, so the gear rod 43 rotates synchronously, and at this time, the locking teeth 54 are locked with the locking pin 44, so when the gear rod 43 rotates, it drives the main rotating roller 51 to rotate synchronously, so that the first electrostatic belt 61, the first insulating belt 63, The second electrostatic belt 62 and the second insulating belt 64 move along the surface of the rubber frame 4 at the same time, so that the surface of the first electrostatic belt 61 and the surface of the second electrostatic belt 62 generate static electricity until the rubber frame 4 is fully opened. At this time, one of the electrostatic belts is located on a side of the rubber frame 4 close to the display screen 3, and the other electrostatic belt is located on a side of the rubber frame 4 away from the display screen 3. Since the ground terminal 41 is located on a side away from the display screen 3, the electrostatic belt on the side away from the display screen 3 loses static electricity, and the electrostatic belt on the side close to the display screen 3 still has static electricity;

[0046] When the display screen needs to be cleaned, the driving member 72 drives the push block 73 to move inward, so that the rubber frame 4 is gradually closed. 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 electrostatic belt 61, the first insulating belt 63, the second electrostatic belt 62 and the second insulating belt 64 are stationary, until the rubber frame 4 is completely closed, the electrostatic belt close to one side of the display screen 3 absorbs the dust on the display screen 3 by static electricity;

[0047] When the rubber frame 4 is opened next time, the first electrostatic belt 61, the first insulating belt 63, the second electrostatic belt 62 and the second insulating belt 64 will be activated again, and when the electrostatic belt with dust passes by the side away from the display screen 3, the electrostatic belt loses its static electricity under the action of the grounding terminal 41, and the cleaning rod 42 can clean and scrape off the dust on the surface of the electrostatic belt.

[0048] In the anti-glare curved OLED display screen for VR equipment described in this embodiment, the width of the first electrostatic belt 61 and the width of the second electrostatic belt 62 are the same as the spacing between the main rotating roller 51 and the secondary rotating roller 52; the width of the first insulating belt 63, the width of the second insulating belt 64, half the circumference of the main rotating roller 51 and half the circumference of the secondary rotating roller 52 are all the same. Through the above arrangement, when the rubber frame 4 is fully opened or fully closed, the first insulating belt 63 and the second insulating belt 64 can be respectively arranged on the two sides of the rubber frame 4, thereby effectively improving the cleaning efficiency.

[0049] In the anti-glare curved OLED display for VR equipment described in this embodiment, the length of the ground terminal 41 is greater than the length of the first electrostatic belt 61 and the length of the second electrostatic belt 62. The above arrangement can effectively eliminate static electricity on the electrostatic belt away from the side of the display screen 3.

[0050] In the anti-glare curved OLED display for VR equipment described in this embodiment, the length of the cleaning rod 42 is greater than the length of the first electrostatic belt 61 and the length of the second electrostatic belt 62. The above arrangement can effectively clean the dust on the electrostatic belt away from the side of the display screen 3.

[0051] In the anti-glare curved OLED display screen for VR equipment described in this embodiment, the housing 2 is provided with a fixing frame 8 movably along the width direction; the display screen 3 is provided on the fixing frame 8; and a second spring 81 is provided between the fixing frame 8 and the housing 2. Specifically, in order to prevent the gap between the two rubber frames 4 from being unable to effectively clean the dust in the gap when the two rubber frames 4 are completely closed, the fixing frame 8 and the second spring 81 are provided, so that the display screen 3 can be pushed to move in a small range during the opening of the rubber frame 4, 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 solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
