Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and specifically to an intelligent eye protection display device and method. Background Art

[0002] With the rapid development of technology, intelligent display screens have been widely used in electronic products such as televisions, computer monitors, tablet computers, and smartphones, becoming an indispensable information display tool in modern society. As a technology aiming to reduce visual fatigue and protect eyesight, intelligent eye protection display screens have emerged. They adjust parameters such as screen brightness and color temperature to simulate the natural light environment, thereby reducing the irritation to the eyes.

[0003] Although the existing intelligent eye protection display screens have achieved certain results in reducing blue light damage and optimizing the visual experience, they still face challenges in specific usage scenarios, such as when watching the display screen at night or in a dimly lit environment. Many users are accustomed to watching the display screen directly without turning on the light, such as watching dramas or playing games late at night. At this time, the high brightness of the display screen forms a strong contrast with the low brightness of the surrounding environment, forcing the eyes to frequently adjust the focal length and pupil size between the high-brightness screen and the almost completely black background, which not only exacerbates visual fatigue but may also cause eye problems such as dry eye and increased myopia. Moreover, relying solely on the brightness of the TV screen itself will cause the eyes to be in a highly tense state for a long time because the eyes need to continuously adapt to this extreme brightness contrast.

[0004] In addition, when the external environmental light is too strong, such as when sunlight shines directly into the room, the existing intelligent eye protection display screens also have deficiencies in reducing screen reflection. Reflection not only affects the viewing effect but may further increase the burden on the eyes. Summary of the Invention

The mounting frame 309 is used to mount the light shielding plate 4 and drive the light shielding plate 4 to rotate.

[0033] A usage method of an intelligent eye protection display device specifically includes the following steps:

[0034] Step 1: When viewing the intelligent eye protection display screen 1, use the light sensor 5 to continuously monitor the intensity of the external ambient light. The light sensor 5 transmits the monitored signal to the intelligent eye protection display screen 1, and the intelligent eye protection display screen 1 automatically adjusts the brightness of the screen of the intelligent eye protection display screen 1 according to the intensity of the light monitored by the light sensor 5, thereby reducing the harm caused to the eyes by the intelligent eye protection display screen 1;

[0035] Step 2: When viewing the intelligent eye protection display screen 1 in a dark environment, start the LED light source 209. The LED light source 209 emits light and irradiates the front side of the light shielding plate 4, thereby increasing the brightness behind the intelligent eye protection display screen 1 and reducing the contrast between the intelligent eye protection display screen 1 and the surrounding environment. At the same time, adjust the brightness of the LED light source 209 according to the intensity of the external ambient light monitored by the light sensor 5, so as to make the brightness of the LED light source 209 match the brightness emitted by the intelligent eye protection display screen 1. When the intelligent eye protection display screen 1 is in a background with a matching brightness, the eyes do not need to frequently perform large-scale visual adjustments between the bright intelligent eye protection display screen 1 and the dark background, thereby reducing the pressure on the eyes to adjust the pupil size and reducing the risk of harming the eyes such as visual fatigue to a certain extent. And adjust the irradiation range of the LED light source 209 according to the viewing distance. Start the first motor 210, and the output end of the first motor 210 drives the gear 212 to rotate through the first connecting rod 211. The rotation of the gear 212 and the engagement of the teeth 205 cause the driving ring 204 to rotate. The rotation of the driving ring 204 drives the driving rod 206 to move circumferentially. Thus, the circumferentially moving driving rod 206 and the spiral driving groove 208 are used in cooperation to cause the rotating ring 207 to drive the LED light source 209 to rotate, thereby adjusting the irradiation range of the LED light source 209 until the LED light source 209 rotates to the most comfortable angle for the eyes to view, and that's it;

[0036] Step 3: When the intelligent eye protection display screen 1 is in an environment with strong light, the intelligent eye protection display screen 1 will produce reflection during viewing. According to the irradiation angle of the light, the second motor 301 and the third motor 304 are started. The output end of the second motor 301 rotates to drive the worm 302 to rotate. The rotation of the worm 302 causes the worm wheel 308 to drive the rotating rod 307 to rotate. The rotation of the rotating rod 307 drives the light shielding plate 4 to rotate around the rotating rod 307 through the mounting bracket 309, so as to adjust the light shielding angle of the light shielding plate 4. The output end of the third motor 304 rotates to drive the rotating bracket 306 to rotate around the second connecting rod 305 through the second connecting rod 305. The rotation of the rotating bracket 306 causes the worm wheel 308 to move circumferentially along the outer wall of the worm 302, and causes the rotating rod 307 to drive the mounting bracket 309 to rotate around the second connecting rod 305, and further drives the light shielding plate 4 to rotate around the second connecting rod 305 through the mounting bracket 309, so as to adjust the light shielding angle of the light shielding plate 4, thereby reducing the irradiation of strong light on the intelligent eye protection display screen 1, reducing the reflection of the intelligent eye protection display screen 1, and reducing the harm to the eyes.

[0037] By installing an adjustable-angle LED light source 209 at the rear side, this device effectively solves the problem of too high contrast between the screen and the surrounding environment when viewing the display screen at night or in a dark environment, reduces the eye adjustment pressure. At the same time, the provided light shielding plate 4 can block excess reflection when the light is too strong, significantly improving the viewing comfort, comprehensively reducing visual fatigue and the risk of eye health, and providing a more healthy and comfortable visual experience for users.

When the intelligent eye protection display screen (1) is in a background with a brightness matching it, the eyes do not need to frequently make large-scale visual adjustments between the bright intelligent eye protection display screen (1) and the dark background, thereby reducing the pressure on the eyes to adjust the pupil size, reducing the risk of harming the eyes such as visual fatigue to a certain extent, and adjusting the irradiation range of the LED light source (209) according to the viewing distance. Start the first motor (210). The output end of the first motor (210) drives the gear (212) to rotate through the first connecting rod (211). The rotation of the gear (212) and the engagement of the teeth (205) cause the driving ring (204) to rotate. The rotation of the driving ring (204) drives the driving rod (206) to move circumferentially, so as to use the circumferentially moving driving rod (206) and the spiral driving groove (208) to cooperate to cause the rotating ring (207) to drive the LED light source (209) to rotate, thereby adjusting the irradiation range of the LED light source (209) until the LED light source (209) rotates to the most comfortable angle for the eyes to view, and that's it; Step 3: When the intelligent eye protection display screen (1) is in an environment with strong light, the intelligent eye protection display screen (1) will produce reflection during viewing. Start the second motor (301) and the third motor (304) according to the irradiation angle of the light. The output end of the second motor (301) rotates to drive the worm (302) to rotate. The rotation of the worm (302) causes the worm wheel (308) to drive the rotating rod (307) to rotate. The rotation of the rotating rod (307) drives the light shielding plate (4) to rotate around the rotating rod (307) as the center through the mounting bracket (309), thereby adjusting the light shielding angle of the light shielding plate (4). The output end of the third motor (304) rotates to drive the rotating frame (306) to rotate around the second connecting rod (305) as the center through the second connecting rod (305). The rotation of the rotating frame (306) causes the worm wheel (308) to move circumferentially along the outer wall of the worm (302), and causes the rotating rod (307) to drive the mounting bracket (309) to rotate around the second connecting rod (305) as the center, and further uses the mounting bracket (309) to drive the light shielding plate (4) to rotate around the second connecting rod (305) as the center, thereby adjusting the light shielding angle of the light shielding plate (4), and further reducing the irradiation of the strong light on the intelligent eye protection display screen (1), reducing the reflection of the intelligent eye protection display screen (1), and reducing the harm to the eyes.
