  • Patent number: 10961402
    Abstract: A photochromic mixture including a photochromic material and a thermosetting transparent polymer material, which are uniformly mixed and dissolved in a solvent, is provided. A formation method of a photochromic device based on the photochromic mixture and a light-transmissive head-mounted display device with the photochromic device are further provided. In the photochromic mixture, the change in the structure of the photochromic material under UV light and room light causes a significant change in its absorption spectrum so the color changes. This property is utilized for the benefits: First, the contrast of the head-mounted display device under strong light irradiation is improved. The display effect is enhanced. Second, the damage to human eye by UV light at the natural environment is reduced. Third, under the same optical requirement, the required energy consumption of self-light-emitting elements in the light-transmissive head-mounted display device is correspondingly reduced.
