Description

Technical Field

[0001] The invention relates to the technical field of optical anti-peeping display screens, in particular to an optical anti-peeping display screen. Background Art

[0002] An optical privacy screen is a screen designed to protect the screen contents from being viewed by bystanders. The optical privacy screen uses polarizing filter technology to polarize light so that the screen contents can only be clearly seen when viewed from a specific angle in the direction facing the screen. When viewed from other angles, the screen contents will become blurred or invisible.

[0003] However, since the display screen will attract dust in the environment due to static electricity when in use, the surrounding dust and particles will be charged, making it easier to be adsorbed to the surface of the display screen. The electrostatic effect is more obvious in the depressions at the corners of the display screen, causing dust to accumulate more easily in the depressions. Dust can scatter light, and accumulated dust will also cause the screen to become blurred and dim, thereby reducing visual quality and affecting picture clarity and color reproduction. The presence of dust will also reduce the contrast of the screen, making the black and white levels of the image not obvious enough, which makes it difficult to recognize details, especially in low-light environments. Dust will also affect the heat dissipation effect of the screen. Too much dust may make the screen hot and increase the risk of failure.

[0004] In actual use, the cleanliness of the surrounding environment and the air quality will have an impact on the display screen. If the working environment is dusty or the air is seriously polluted, the surface of the display screen may attract dust due to static electricity. Especially in a dry environment, static electricity can easily generate and attract tiny particles in the air, making the display screen prone to dust accumulation. Secondly, if the computer is used in an air-conditioned or heater environment, dust and particles in the air will be more easily blown onto the surface of the display screen.

[0005] Since the accumulation of dust on the display surface is a slow process, the existing method of cleaning the periphery and surface of the display screen is usually manual cleaning. The operator needs to manually use a scraper to slide along the recessed areas around the display screen to scrape off the accumulated dust. During the operation, it is impossible to effectively apply uniform force to the scraper. Excessive force may cause the edge of the film to be damaged, broken or stretched, causing the edge of the film to lose its original stickiness and reduce the adhesion of the film.

[0006] Secondly, when using the computer for a long time, especially under high brightness or high temperature conditions, the edge of the display may be subjected to greater pressure and thermal stress, causing the display material to change, causing the privacy film on the edge of the display to warp or curl, resulting in edge warping or curling. Long-term edge warping or curling problems make the exposed part of the display lack protection and vulnerable to external interference, which will aggravate the damage to the screen, such as causing the display material to break or delaminate. This will cause permanent damage to the display, requiring the entire display to be replaced, increasing repair costs.

[0007] The existing method is usually to manually press the raised part of the edge of the display screen to make the anti-peep film and the display fit again, and then apply silicone oil for secondary protection. When adding silicone oil, it is impossible to apply it evenly. The excess silicone oil will form a thick coating on the screen surface, affecting the sensitivity and accuracy of the touch, resulting in inaccurate touch or slow response. Long-term use will also cause yellowing at the edge of the film.

[0008] To this end, an optical anti-peeping display screen is proposed. Summary of the invention

[0043] The edge scraping assembly includes a protective plate 21, which is symmetrically fixedly connected to the outer wall of the display body 1. A central rod group 22 is arranged in a rectangular array on the side where the two protective plates 21 are close to each other.

The outer walls of the central rods of the central rod group 22 arranged in the rectangular array are fixedly sleeved with pulleys 23, and the outer wall of each pulley 23 is connected to a synchronous belt 24 for transmission. The outer wall of the synchronous belt 24 is fixedly connected with a fixing block 25, and the end face of the fixing block 25 close to the display screen body 1 is fixedly connected with a rectangular hollow tube 26, and a filter is installed inside the end of the rectangular hollow tube 26 away from the display screen body 1, and the side of the rectangular hollow tube 26 close to the display screen body 1 is in contact with the display screen body 1, and the shape of the rectangular hollow tube 26 is set to be a trapezoid, and a triangular scraper 27 is fixedly connected to the outer wall of the rectangular hollow tube 26, and a communicating cleaning side block 28 is fixedly connected to the outer wall of the rectangular hollow tube 26, and the cleaning side block 28 is connected to the inside of the rectangular hollow tube 26, and an air outlet is opened at the end of the cleaning side block 28 away from the rectangular hollow tube 26;

[0044] Among them: the setting of a pair of protection plates 21 plays a role in providing stability to the synchronous belt 24 during the process of the pulley 23 driving the synchronous belt 24 to convey, avoiding the phenomenon of deviation that causes the rectangular hollow tube 26 to separate from the surface of the display screen body 1; the setting of the filter net inside the rectangular hollow tube 26 plays a role in filtering impurities and large particles of dust in the airflow collected by the rectangular hollow tube 26 around the display screen body 1; the rectangular hollow tube 26 is set to a hollow shape close to the inner wall slope of one side of the display screen body 1, which plays a role in compressing the air inside the right-angled rectangular hollow tube 26 and accelerating the air flow to form a high-speed air flow; the setting of the oblique triangular scraper 27 at the air outlet of the cleaning side block 28 plays a role in creating an airflow barrier to clean up impurities and dust attached to the surface of the triangular scraper 27.

[0045] Better: the triangular scraper 27 is arranged on one side of the forward direction of the rectangular hollow tube 26, and is arranged to be wide at the end away from the display screen body 1 and narrow at the end close to the display screen body 1. When the triangular scraper 27 is hanging on the wall around the display screen body 1, it guides the scraped impurities and dust to avoid the accumulation of excessive impurities and dust, thereby better improving the cleaning effect of impurities and dust.

[0046] The protection plate 21 is provided with a variable speed flow guide assembly for introducing airflow into the rectangular hollow tube 26, wherein;

[0047] The speed change guide assembly includes a vertical middle bearing shaft 31 and a driving gear 32. The vertical middle bearing shaft 31 is fixedly connected to the top of the driving gear 32, and the bottom end of the vertical middle bearing shaft 31 extends to the outside of the bottom end of the rectangular hollow tube 26. The outer wall of the protection plate 21 is fixedly connected to a toothed plate 33, and the driving gear 32 is meshed with the toothed plate 33. A middle load-bearing rod 34 is provided on the side of the vertical middle bearing shaft 31 close to the display screen body 1. One end of the middle load-bearing rod 34 close to the driving gear 32 is fixedly connected to the inside of the rectangular hollow tube 26, and one end of the middle load-bearing rod 34 away from the driving gear 32 is rotatably connected to a transverse middle bearing shaft 35. The ends of the transverse middle bearing shaft 35 close to the vertical middle bearing shaft 31 are both slidably connected to an L-shaped linkage rod 36 in a circular uniform array. The transverse middle bearing shaft 35 is away from the vertical middle bearing shaft 31. One end of the bearing shaft 31 is fixedly connected to a linkage gear 37, and two auxiliary bearing rods 39 are arranged on the side of the middle bearing rod 34 close to the display screen body 1, and one end of each auxiliary bearing rod 39 close to the tooth plate 33 is fixedly connected to the inside of the rectangular hollow tube 26, and one end of each auxiliary bearing rod 39 away from the tooth plate 33 is rotatably connected to a driven shaft 310, and one end of each driven shaft 310 close to the vertical middle bearing shaft 31 is fixedly connected to a driven gear 38, and each driven gear 38 is meshed with the linkage gear 37, and the gear ratio of the two driven gears 38 to the linkage gear 37 is 1:3, and the surfaces of the driven gears 38 and the linkage gear 37 are provided with penetrating ventilation holes, and one end of each driven shaft 310 away from the vertical middle bearing shaft 31 is fixedly connected to a fan 311;

[0048] Among them: the meshing setting of the linkage gear 37 and the driven gear 38 plays a role in accelerating the angular velocity of the auxiliary bearing rod 39, and the setting of the ventilation holes opened on the surfaces of the linkage gear 37 and the driven gear 38 plays a role in helping air move into the rectangular hollow tube 26.

[0049] Better: the vertical center bearing shaft 31, the horizontal center bearing shaft 35 and the linkage gear 37 are arranged at the center line position inside the rectangular hollow tube 26, so that the fan 311 can disturb the air while making the internal airflow more stable, making the air flow at the air outlet position more uniform and stable.

[0050] A silicone oil coating component is provided on one side of the rectangular hollow tube 26 away from the triangular scraper 27 for coating the display screen with silicone oil for protection after the edge of the display screen is scraped off.

[0051] The silicone oil application assembly includes an oil delivery cylinder 41 and an oil storage cylinder 42. The oil delivery cylinder 41 is sleeved on the outside of the oil storage cylinder 42. The outer wall of the oil delivery cylinder 41 is fixedly connected to a support rod, one end of the support rod is fixedly connected to the outer wall of the rectangular hollow tube 26, an oil outlet 43 is opened on the outer wall of the oil storage cylinder 42, an oil guide pipe 44 is fixedly connected to the side of the outer wall of the oil delivery cylinder 41 away from the oil outlet 43, the oil guide pipe 44 is communicated with the oil delivery cylinder 41, and the end of the oil guide pipe 44 away from the oil delivery cylinder 41 is fixedly connected to a sponge pad 45, and the end of the oil storage cylinder 42 away from the display screen body 1 is fixedly connected to an oil inlet pipe 46, the oil inlet pipe 46 is communicated with the oil storage cylinder 42, and the other end of the oil inlet pipe 46 is threadedly connected to an oil cap 47.

[0052] Among them: a gap is set between the outer wall of the oil delivery cylinder 41 and the inner wall of the oil storage cylinder 42, which plays a role in quickly collecting the silicone oil flowing out of the oil outlet 43 and quickly merging it into the oil guide pipe 44 during the movement of the oil delivery cylinder 41. The staggered setting of the oil outlet 43 and the oil guide pipe 44 plays a role in controlling the speed at which the silicone oil flows into the oil guide pipe 44.

[0053] The above implementation works as follows:

[0054] The initialization steps are as follows:

[0055] The display screen body 1 is placed horizontally on the table, and the rectangular hollow tube 26 is located at the upper end surface of the display screen body 1. The oil cap 47 is manually unscrewed from the end of the oil inlet pipe 46. The oil inlet pipe 46 and the oil cap 47 are in a separated state. Then, silicone oil is dripped into the oil inlet pipe 46. When the silicone oil fills the inside of the oil delivery cylinder 41, the silicone oil is stopped. The oil cap 47 is manually matched with one end of the oil inlet pipe 46. At this time, the outer thread of the oil cap 47 is matched with the inner thread of the oil inlet pipe 46. The oil cap 47 is rotated in the opposite direction again to be fastened to the oil inlet pipe 46.

[0056] The physical principles involved:

[0057] Bernoulli's law: Bernoulli's law is based on the continuity equation and the principle of conservation of energy. It is applicable to situations where the flow is incompressible, has low viscosity and is stable. According to Bernoulli's law, for an ideal fluid along a streamline, when its velocity increases, the pressure decreases, while the height remains unchanged. The specific statement is as follows;

[0058] Velocity of a fluid: When a fluid passes through a pipe or flow device, if the cross-sectional area becomes narrower (for example, a pipe constriction), the mass flow rate remains constant according to the continuity equation. Since mass flow rate is proportional to velocity, as velocity increases, the flow rate of the fluid through the narrow section also increases.

[0059] Changes in pressure: According to the principle of conservation of energy, as the velocity increases, the kinetic energy of the fluid will also increase. According to Bernoulli's principle, when the velocity increases, the kinetic energy of the fluid increases, so the pressure will decrease. In other words, the increase in the kinetic energy of the fluid is achieved by reducing its static pressure.

[0060] The working steps are as follows:

[0061] like Figure 2 - Figure 4 As shown, the operator electrically controls the external starter motor to be energized through the external control panel, and the output end of the external starter motor drives a plurality of center rod groups 22 to rotate, and the center rod group 22 drives the synchronous belt 24 through the pulley 23 for transmission, and the synchronous belt 24 drives the rectangular hollow tube 26 to move along the trajectory around the display screen body 1 through the fixed block 25, and the inclined end of the inner wall of the rectangular hollow tube 26 is always facing the center of the display screen body 1. During the movement of the rectangular hollow tube 26, the rectangular hollow tube 26 drives the triangular scraper 27 on the side of the forward direction to move on the surface of the display screen body 1 in the same trajectory, and the end surface of the triangular scraper 27 that is in contact with the surface of the display screen body 1 scrapes off the dust on the motion trajectory, thereby performing a dust scraping and dust cleaning operation around the display screen body 1, and the scraped impurities and dust will be dispersed along the inclined surface of the triangular scraper 27 toward the direction close to the display screen body 1, and the end surface of the rectangular hollow tube 26 that is in contact with the display screen body 1 will simultaneously perform a pressing edge treatment on the surrounding of the display screen body 1.

[0062] like Figure 5 - Figure 7 As shown, when the rectangular hollow tube 26 moves around the display screen body 1, the rectangular hollow tube 26 drives the driving gear 32 to rotate through the vertical center bearing shaft 31 and the tooth plate 33, and the driving gear 32 drives the vertical center bearing shaft 31 to rotate. The vertical center bearing shaft 31 drives the horizontal center bearing shaft 35 to rotate synchronously through a number of evenly distributed L-shaped linkage rods 36, so that the horizontal center bearing shaft 35 drives the linkage gear 37 at the other end to rotate, and the linkage gear 37 drives the driven gears 38 meshing on both sides to simultaneously drive a pair of fans 311 to rotate. At this time, because the gear ratio of the driven gear 38 to the linkage gear 37 is 1: 3. The linkage gear 37 drives the driven gear 38 to rotate at three times its own angular velocity. The pair of fans 311 both disturb the air toward the center of the display screen body 1 while rotating. The fan blades of the fan 311 rotate and push the surrounding air, causing it to flow at high speed. The high-speed flowing air will closely adhere to the curved surface of the fan blades of the fan 311, and then flow along the curved shape of the blades. Because the air flowing on the blades must pass through the curved part of the blades in a short time, it is accelerated, which leads to an increase in the air flow rate, and then the air is accelerated to move toward the rectangular hollow tube 26;

[0063] The accelerated air is filtered by the filter when it enters the end of the rectangular hollow tube 26 away from the display screen body 1. The filtered air enters the cleaning side block 28 and the narrower end of the rectangular hollow tube 26 under the push of the fan 311. It can be seen from the above Bernoulli's law that when a fluid passes through a pipe or a flow device, if the cross-sectional area becomes narrower, for example, the pipe contracts, according to the continuity equation, the mass flow rate remains constant. Since the mass flow rate is proportional to the speed, when the speed increases, the flow rate of the fluid through the narrow part will also increase, and according to the principle of conservation of energy, as the speed increases, the kinetic energy of the fluid will also increase. According to Bernoulli's principle, when the speed increases, the kinetic energy of the fluid increases accordingly, and then the airflow is accelerated in the rectangular hollow tube 26 and diverted toward the air outlet of the rectangular hollow tube 26 and the cleaning side block 28, and then the high-speed airflow is released to the outside from the air outlet of the rectangular hollow tube 26 and the cleaning side block 28. The high-speed airflow released at the end of the rectangular hollow tube 26 flows over the surface of the display screen body 1 and takes away impurities and dust attached to its surface. The high-speed airflow released at the air outlet of the cleaning side block 28 flows over the surface of the triangular scraper 27 and takes away impurities and dust attached to its surface, thereby cleaning the impurities and dust on the surface of the display screen body 1 and its surroundings.

[0064] like Figure 5 - Fig. 9 As shown, when the rectangular hollow tube 26 drives the oil delivery cylinder 41 to move along the track around the display screen body 1, the oil storage cylinder 42 supplies oil to the inside of the oil delivery cylinder 41 through the oil outlet 43, and then guides the silicone oil to the inside of the oil guide pipe 44 through the inner wall of the oil delivery cylinder 41. The silicone oil in the oil guide pipe 44 will soak the sponge pad 45, and the silicone oil will be evenly applied on the running track through the sponge pad 45. When the oil delivery cylinder 41 moves to the level of the display screen body 1, the oil storage cylinder 42 can supply oil normally through the oil outlet 43. When the oil delivery cylinder moves to the level of the display screen body 1, the oil outlet 43 is located below the oil guide pipe 44. The tube 44 has a certain depth and can store some silicone oil, so that the sponge pad 45 can continue to apply the coating operation. When the oil cylinder 41 moves to a point where it is perpendicular to the display screen body 1, the oil outlet 43 is located above the oil guide tube 44. Since the silicone oil is consumed during the coating operation, the oil level is lower than the oil outlet 43, so that the silicone oil inside the oil storage cylinder 42 cannot flow out. The oil cylinder 41 continues to move forward and continues to consume the remaining silicone oil inside the oil guide tube 44. When the position of the oil cylinder 41 is restored, the silicone oil inside the oil guide tube 44 is completely consumed. At this time, the operator can electrically control the external starting motor to cut off the power through the external control panel.
