Embodiment Construction

[0060] To enable those skilled in the art to better understand the technical solutions of the present invention, the protection device, protection method, wearable device and display device provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0061] figure 1 This is a schematic diagram of the structure of a protection device provided by Embodiment 1 of the present invention, such as figure 1 As shown, the protection device includes: a radiation detection module 11, a data processing module 12, and an electrochromic module 13.

[0062] The radiation detection module 11 is used to detect the radiation current of blue light. The data processing module 12 is used to convert the radiation current into a radiation voltage, perform a cumulative process on the radiation voltage to obtain a cumulative result, and determine whether the cumulative result is greater than a radiation threshold. The electrochromic module 13 is used fo...

Abstract

The invention discloses a protection device, a protection method, a wearable device and a display device. The protection device includes: a radiation detection module, a data processing module, and an electrochromic module; the radiation detection module is used to detect the radiation current of blue light; the data processing module is used to convert the radiation current into a radiation voltage for The radiation voltage is accumulated and processed to obtain an accumulated result, and it is judged whether the accumulated result is greater than the radiation threshold; the electrochromic module is used to open the protective layer to block blue light radiation if the data processing module determines that the accumulated result is greater than the radiation threshold. The invention avoids damage to eyes caused by blue light.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a protection device, a protection method, a wearable device and a display device. Background technique [0002] Among visible light, blue light is a kind of high-energy shortwave light with great energy. Blue light is ubiquitous in daily life, such as in all kinds of energy-saving lamps, LED lamps, incandescent lamps and sunlight that are exposed to everyday. As the display device is more and more widely used, blue light is also commonly present in the light emitted by the display device. [0003] Blue light has a strong concealment, so it is not easy to detect. Blue light can easily penetrate the lens of the eye to reach the retina, and can quickly accelerate the oxidation process of the macular area of ​​the eye, thereby causing great damage to the eye. Summary of the invention [0004] The invention provides a protection device, a protection method, a wearable device and a...
