7results about How to "Relieve visual fatigue" patented technology

The application belongs to the technical field of lighting lamps, and particularly relates to a three-dimensional full-space wireless sliding table lamp with anti-dazzle and eye protection, which comprises a supporting frame, a lifting mechanism, a horizontal adjusting mechanism, a wireless sliding connecting assembly, a balance structure and a bidirectional light-emitting anti-dazzle assembly. A placing seat is fixedly connected to the bottom of the supporting frame, and a first sliding groove is formed in the vertical direction in the middle of the supporting frame. The lifting mechanism comprises an adjusting plate arranged at the end of a fixed cylinder, and a positioning rail is fixedly connected to the outer wall of the adjusting plate. The adjusting plate is clamped on the inner wall of the first sliding groove through the positioning rail. The LED upper lamp plate with a front inclination angle is arranged to effectively supplement the background light of the working environment. The bidirectional light-emitting mode significantly reduces the brightness ratio between the center of the working area and the surrounding environment, reduces the light-dark contrast, relieves the visual fatigue caused by frequent pupil adjustment of the human eye, and prevents myopia from the optical and physical aspects.

The invention provides a high-image-quality light field near-eye display system and an aberration pre-correction method, which cooperatively solve the problem of poor display imaging quality caused by boundary and system aberration of element views in light field near-eye display through the controllable diffusion effect of a holographic function screen and the correction effect of an aberration pre-correction model. Boundaries between element views are eliminated through the holographic function screen, continuous motion parallax and natural visual experience are provided, an eye box and a field angle are enlarged to a certain extent, and immersion is enhanced; the real three-dimensional characteristic of light field display is kept while high image quality is guaranteed, accurate focus prompt can be provided, visual fatigue is effectively relieved, and the VAC problem is solved.

The utility model discloses a mobile phone light supplementing mechanism, and relates to the technical field of stacking devices and the technical field of mobile phone light supplementing, the mobile phone light supplementing mechanism comprises a light supplementing assembly, and the light supplementing assembly is detachably connected with a mobile phone and / or a mobile phone shell; the light supplementing assembly is provided with an annular shell, and an LED lamp panel is arranged in the annular shell. A transparent cover is arranged above the LED lamp panel, and the transparent cover is connected to the annular shell in a buckled mode. According to the mobile phone shell, when the mobile phone shell is used, the light supplementing assembly is fixed to a mobile phone and / or the mobile phone shell, then the LED lamp panel is turned on, light penetrates through the transparent cover and then illuminates the outer side space, and therefore the brightness of light outside the mobile phone is improved, the light supplementing effect is good, and the service life of the mobile phone shell is prolonged. Therefore, visual fatigue of a user is relieved, and damage of mobile phone brightness to eyes of the user is reduced.

The present disclosure provides a screen adjusting method and device, a storage medium and an electronic device, wherein the method comprises: acquiring a continuous use time of a screen; determining a fatigue degree of a user's eyes according to the continuous use time and a preset fatigue degree corresponding relationship, wherein the fatigue degree corresponding relationship is a mapping relationship between the continuous use time and the fatigue degree; determining a color gamut compression coefficient based on the fatigue degree, and compressing an original color gamut of the screen according to the color gamut compression coefficient to obtain a compressed target color gamut; and adjusting the color gamut of the screen according to the target color gamut. By compressing the color gamut of the screen, the screen color becomes relatively dull, reducing the visual impact of the light of the screen of the electronic device on the user's eyes, thereby relieving the visual fatigue degree of the user when using the electronic device for a long time.

The application discloses a kind of methods and terminals for automatically adjusting display mode of virtual reality equipment, when the ambient light data outside virtual reality equipment is low, switch to the first display mode of anti-blue light, and the first display mode and the second display mode are linked, not only can reduce the harm of blue light, but also reduce the visual impact of high-light area on eyes, relieve visual fatigue. Furthermore, the second display mode and the third display mode are linked, which saves device energy consumption, improves device endurance time, and the third display mode can also be turned on according to user operation behavior. Therefore, different display modes are automatically switched according to the current user behavior and ambient light, providing personalized visual experience and device management.

The utility model discloses a plug -in type glasses. Including glasses frame, glasses leg, first plug -in piece and second plug -in piece, glasses frame is connected with first plug -in piece through hinge, and the end surface of first plug -in piece is embedded with at least one spring top bead, and the ball of spring top bead is in the surface of first plug -in piece, and one mounting port is arranged to the one end of glasses leg, and second plug -in piece is fixedly installed in mounting port, and the outside end of second plug -in piece is provided with the plug -in interface that can satisfy the insertion of first plug -in piece, and the inner wall of plug -in interface is provided with the lock groove that can satisfy the embedding of the ball of spring top bead. The utility model forms plug -in type connection, makes glasses leg can separate with glasses frame to the binding between each other, can replace glasses leg of different appearance style according to the personal preference, realizes user's own DIY design, slows down visual fatigue, can replace pertinence when glasses leg or glasses frame is damaged, cannot integral protection, effectively saves resources.
